CAN I HAVE SOME HELP!!!!!!!!!!

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.

To perform these roles, the plasma membrane needs lipids, which make a semi-permeable barrier between the cell and its environment. It also needs proteins, which are involved in cross-membrane transport and cell communication, and carbohydrates (sugars and sugar chains), which decorate both the proteins and lipids and help cells recognize each other.

Answer:

__B is the correct option__

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.

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.

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.

Heterosporous plants are the ones that produces two different type of spores. Spores can be different in shape and size and that's the name heterosporous. It produces two different shaped spores to differentiate between male and female gametophytes

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.

Answer:

SO2 ==> inorganic compound

Cl2 ==> inorganic elemental molecule

C6H6 ==> organic compound

Explanation:

k=element

SO2=inorganic compound

cl2=inorganic elemental molecule

C6H6=organic compound is your answer.

happy new year (:

The ecological approach emerged as a reaction to the lab approach, which was considered sanitized and perhaps too controlled. What can happen in a lab cannot necessarily happen outside and vice versa.

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.

Following these procedures is important to maintain biosafety standards and avoid accidents that affect the work in progress or the health of staff.

C)increases in response to increasing light intensity but only to a certain

point

The intensity of photosyntheis increases until the intensity of light reaches 50000 luxes after 100000 luxes the rate of photosynthesis will decrease because the intense light damages the tissues.

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.

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.

Following these procedures is important to avoid chemical or biological contamination of both the environment and people.

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.

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.
