Patterns of inheritance are usually more complicated than what is predicted by Mendelian genetics. Explain four possible exceptions to Mendelian genetics involving the inheritance patterns of a single gene and provide an example of each.
Answer:
Please find the explanation of the four possible exceptions to Mendelian genetics below.
Explanation:
Genetics, generally, has to do with how genes are inherited or transferred from parents to offsprings. Gregor Mendel, however, explained this concept in his principles of inheritance called Mendelian genetics. There are, however, exceptions to this mendelian principle called Non-mendelian pattern of inheritance i.e patterns of inheritance that do not follow Mendel's principles. Four of them are explained below:
- Incomplete dominance- This non-mendelian inheritance pattern occurs when one allele of a gene does not completely mask its allelic pair, but instead forms an intermediate phenotype. This is in contrast with Mendelian genetics that proposes complete dominance. For example, a red and white flower produce a pink flower (intermediate).
- Codominance- This is another non-mendelian inheritance where two alleles of a gene are simultaneously expressed. For example, roan cattles is a combination of both red and white hairs.
- Multiple alleles: Some traits in a population are controlled by more than two alleles, as explained in mendelian inheritance. Examples of trait controlled by multiple alleles is height in humans.
- Sex-linked inheritance: Some traits are controlled by genes on sex chromosomes i.e. X and Y chromosomes. This genes exhibit inheritance pattern that are different from Mendel's. Example is haemophilia disease controlled by an affected gene on the X-chromosome.

what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part E
Answer:
What the scientist is doing incorrectly is working on a computer console with several monitors, having tubes and flasks of chemicals or biological substances on the same work table, many of which have fallen to the floor breaking and spilling their contents.
Explanation:
In the image it can see that a scientist works with a computer, placed in a long table where there are a lot of flasks and test tubes, many of which contain substances and have fallen to the ground, breaking and perhaps spilling their contents. This is a incorrect practice, as there should be a console for the computer, while the laboratory material should be on separate work tables.
what could he do to make their work in the lab safer? Separate the work spaces by having a computer work area separate from the lab area.Keep the work area clean, avoiding falling containers and spilling chemical or biological substances.why is it important to follow these procedures?Following these procedures is important to maintain biosafety standards and avoid accidents that affect the work in progress or the health of staff.

Using its long tail and long hind legs, the Ord's kangaroo rat can jump 2 m in the air as it hops away from predators, such as snakes and owls [A, 4 marks] a. How would Lamarck account for the origin of the long hind legs of the Ord's kangaroo rat? b. How would Darwin?
Answer and Explanation:
a. According to Lamarck, the origin of the long hind legs of the Ord's kangaroo rat is acquired due to extensive use of the muscle legs to jump. Such physical characteristics could be transmitted to future generations. This theory is called Neo-Lamarckism.
b. Darwin, on the other hand, theorized that in a population of Ord's kangaroo rat, there was an individual whose characteristics, long tail and hind legs, had more chances of escaping its predator and, consequently, could survive and reproduce. This theory is called Darwinism.
a farmer wants to know which will allow his plants to produce the most food. he gave no fertilizer to 10 plants fertilizer a to 10 plants and fertilizer b to 10 plants. all of his plants were the same were planted in the same soil and we given the same amount if water after six weeks the farmer weighted the total amount of food produced by each group
Answer:
It depends on the optimum dosage of NPK.
Explanation:
The farmer gain more productivity from that type of fertilizer which have optimum dosage of nitrogen, phosphorus and potassium fertilizers because these three fertilizer needed by the plant in large quantity and having great contribution in the yield of plant so if ''fertilizer a'' has optimum dosage of these three nutrients so we can say that ''fertilizer a'' produces more food as compared to no fertilizer and ''fertilizer b'' whereas if ''fertilizer b'' has optimum dosage of these nutrients so ''fertilizer b'' produces more food.

You overhear your mom and dad talking about having a well installed in your yard. What advice can you offer them about determining the placement and potential effectiveness of the well? Think about what you know about how wells factor into the groundwater systems running below the surface of the Earth.
Answer:
Built well where water table present nearer to surface.
Explanation:
My advice for them about determining the placement and potential effectiveness of the well is that the well should be installed where the groundwater present nearer to the surface, the reason behind this advice is that minimum work and energy will be used for digging well. If the water table is present very deep, more work and energy will be utilized on the digging of the well. Those areas where more rainfall occurs, the depth of water table is less as compared to arid zones because due to more rainfall more water goes inside the soil and the water table rises.

1. Negative feedback is bad for your body. True or false 2. Both negative and positive feedback works in a loop. True or false. 3. Feedback loops are open systems of information. 4. There are feedback systems found in the environment and mechanical systems.
Answer:
1. False
2. True
3. True
4. True
Explanation:
Negative feedback (or balancing feedback) happens when some capacity of the yield of a framework, cycle, or system is taken care of in a way that will in general decrease the variances in the yield, regardless of whether brought about by changes in the input or by different unsettling influences.
Though certain feedback will in general prompt unsteadiness through outstanding development, wavering or disorganized conduct, negative feedback for the most part advances steadiness. Negative feedback will in general elevate a settling to balance, and diminishes the impacts of bothers. Negative feedback loops in which the perfect measure of adjustment is applied with ideal planning can be entirely steady, exact, and responsive.

What is the function of cholesterol?
to keep the cell membrane from falling apart
to line the arteries of organisms
to store energy
to give us quick energy
Answer:
to store energy
Explanation:
Its main function is to maintain the integrity and fluidity of cell membranes and to serve as a precursor for the synthesis of substances that are vital for the organism including steroid hormones, bile acids, and vitamin D. Cholesterol is essential for making a number of critical hormones, including the stress hormone cortisol. Cholesterol is also used to make the sex hormones testosterone, progesterone, and estrogen. 2 The liver also uses cholesterol to make bile, a fluid that plays a vital role in the processing and digestion of fats.
what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part d
Answer:
What the scientist is doing incorrectly is disposing of a chemical or biological waste in the common sewer.
Explanation:
One of the most important biosecurity measures is the proper disposal of chemical and biological waste. What the shown scientist is doing incorrectly is disposing of potentially harmful substances in a normal sewer.
What could he do to make their work in the lab safer?The main thing that must be done to maintain a safe laboratory is to perform proper disposal of chemical or biological waste, which must be placed in airtight containers and transported to a location for safe disposal.
Chemical waste is usually taken to a landfill where it can be neutralized. Biological waste is transported to incinerators for complete disposal. Why is it important to follow these procedures?Following these procedures is important to avoid chemical or biological contamination of both the environment and people.

A group of researchers wants to develop an experiment to determine whether a new drug effectively treats cancer. The researchers want to inject the drug in hamsters first to determine whether there are any potentially serious side effects.
Part A: What are some possible ethical issues with this type of testing?
Part B: While conducting the experiment, the researchers find cancer stops spreading, and they declare the new drug is responsible. Is this a good assumption? Explain.
Answer:
Part A: The animals are used for examining and determining the effect of a particular new drug for the treatment of the diseases and disorders before they are examined over humans. This practice is called as clinical trial.
The ethical issue associated with given type of testing is that animals have right to live and survive. They should not be subjected to the treatment where they experience harm or even death.
Part B: Those assigned to the control take a sugar pill. The only thing you want to vary across groups when you're conducting an experiment is the treatment. Since taking pills is a part of taking medication (the treatment), medical experiments often employ something called a placebo-controlled study where outcomes for those who are randomly assigned to take the medication are compared to outcomes for those who are randomly assigned to take a sugar pill. The sugar pill is expected to have no effect, so it serves as a useful baseline to compare the treatment to.
Answer:
The current code of ethics to be upheld in science experiments are as follows: the experiment must contain a clear scientific purpose, the animals must be housed and provided with care, the animals must be legally acquired, the least amount of suffering must be ensured, and the animals can only be used when it is entirely necessary.
In this paragraph, we can see the plan does not fit the code of ethics entirely- because this is a new drug, we can not be sure that this experiment will not be fatal for the animals, and that they will not suffer tremendously before passing on. The medicine should be tested first on a sample which is not living.
Explanation:
What term describes parts of the body that are made from different kinds of cell
Answer:
The term that describes the parts of the body with different kindsof cells is organs, which in turn are made up of different tissues.
Explanation:
The cell is the structural and functional unit of all living beings, with the capacity to multiply and unite to form tissues.
Each tissue is a differentiated or specialized structure, formed by groups of cells of the same type, such as muscle, nerve, connective, cartilage and bone tissue, among others.
The specialized tissues in turn form organs, with specific structures and functions, such as muscle, brain and nerves or bones and joints. For this reason, organs are different body parts, formed by different kinds of cells.
If an organelle is selectively
permeable what can we infer
about its function?
MULTIPLE CHOICE
Answer:
What can be inferred about the function of a selectively permeable organelle is that organelle allows some molecules to pass trough (option C).
Explanation:
Selective permeability is a characteristic, present in the membranes, which allows the passage of some substances and prevents the passage of others, according to their structure.
An example of selective permeability is found in cell membranes, whose hydrophobic nature allows the passage of apolar molecules easily, limiting or preventing the passage of polar molecules and ions.
The other options are not correct because:
A. Not all molecules can pass through a semi-permeable organelle.
B. The semipermeable organelle does not prevent the passage of any substance.
C. Semi-permeable organelle does not allow the passage of large molecules easily.
The spinal cord relays messages between the body and the brain. These messages control body functions like movement, bladder and bowel control and breathing. Each vertebra has a pair of spinal nerves that receive messages from the body (sensory impulses) and send messages to the body (motor impulses). The spinal nerves are numbered 1 to 55 from the neck down. The first eight as seen here are the vertebrate and send messages to the back of the head, neck, shoulders, arms, hands and diaphragm. A) cervical B) lumbar C) sacral D) thoracic

select the correct answer sickle cells  disease is a hereditary mutation that causes The red blood cells to the form decreasing their ability to carry oxygen based on the image what kind of mutation occurs to cause Sickel cell disease
Answer:
Sickle cell disease is due to a type of substitution mutation.
Explanation:
Sickle cell disease is a condition that is transmitted from parents to children in an autosomal recessive inheritance pattern. It is due to a mutation that is capable of altering the shape of the erythrocyte, as well as its ability to circulate and carry oxygen.
The mutation that occurs in sickle cell disease is due to an alteration in the β-chain of hemoglobin, caused by the substitution of thymine base by adenine in the DNA that determines it. As a result, valine replaces glutamic acid in the β-chain amino acid sequence, with the consequences described.
The other options are not correct because deletion, duplication and translocation correspond to chromosomal mutations, not responsible for sickle cell disease.how can you demonstrate that plant prepare their own food on its leaves ? write with experiment
