Answer:
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome .
The process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.
Crossing over, also known as recombination, is the interchange of genetic material between non-sister chromatids of homologous chromosomes.This process (crossing over) occurs in Meiosis I, specifically during Prophase I.Crossing over during Prophase I and the independent assortment of homologous chromosomes during Metaphase I represent meiotic processes that help to increase genetic variation in gamete (sex) cells.In conclusion, the process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.

Elisa feels tired because she has a condition that affects whether the right molecules are getting to her cells. If her body were functioning correctly, this is what would happen with oxygen
Answer:
The oxygen is available in a right amount.
Explanation:
The oxygen is available in a right amount because her body were functioning correctly and we know that our body functioning correctly if it gets oxygen in a right amount otherwise body will not perform correctly its functions. The tiredness Elisa feels is due to her routine work which can be eliminated by doing rest for sometime so after resting sometime she feel better and active.
Elsie has the right amount of oxygen needed by the cells if her body were
functioning correctly.
Oxygen is an important in the body's metabolic processes and help in the
metabolism of glucose to energy which is needed by all the cells of the
body. When the oxygen is deficient , the blood won't be able to pump
oxygen through the blood to body cells.
This then results in decreased cell functions and metabolism thereby causing tiredness , cell damage and death if severe.

Will give brainliest to the first correct answer! Describe the factors influencing chemical bonds and the characteristics of an ionic and a covalent bond.
Answer:
FACTORS INFLUENCING CHEMICAL BONDS
Ionic bonding is a chemical bond between a positive ion and negative ion. Ionization energy, electronegativity, and lattice energy are the factors that influence the formation of ionic bonds of elements.
CHARACTERISTIC OF IONIC BONDS
Ionic compounds are hard and brittle. Ionic compounds dissociate into ions when dissolved in water. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not. An ionic compound can be identified by its chemical formula: metal + nonmetal or polyatomic ions.
CHARACTERISTIC OF COVALENT BOND
Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.
State one specific response of the body to the increase in blood glucose level that would account for the changes that begin about 30 minutes after eating the cookie.
Answer:
Secrete insulin.
Explanation:
If the body has increase in blood glucose level due to eating of cookies, our body secrete insulin in order to regulates blood glucose level. If there is too much glucose in the body, the body secretes more insulin in order to regulate the glucose level in the blood whereas if there is low glucose level in the blood, our body secrete glucagon through pancreas in order to raise blood glucose level.

Answer:
According to the diagram, step 3 indicates the S phase of cell cycle, which corresponds to the DNA replication phase.
Explanation:
In the S phase of the cell cycle the nucleus contains twice the amount of its genetic charge, due to increased DNA replication, resulting in each chromosome forming two chromatids.
This is a relatively long phase, and is part of the preparation process that occurs before an imminent division. In the diagram it is indicated by the number 3.
The S phase is named for the abbreviation of Synthesis.

2. How far apart are Y and L? Give your answer in map units.
Answer:20
Explanation:
its 20
Answer: The number of the two recombinant types is 200, divide by the total number of offspring is 1000, and multiply by 100, so the map unit is 20.
What are recombinant types?
The heterozygous dominant species, in this case, is YyLl, where Y stands for the dominant trait over y and T stands for the dominant trait over t.
Recombinant species will exhibit features that are heterozygously expressed in both the dominant and recessive forms), and these traits are Yyll: 100 and yyLl: 100.
Therefore, The number of the two recombinant types is 200, divide by the total number of offspring is 1000, and multiply by 100, so the map unit is 20.

[25 pts] Why could a spinal injury leave someone paralyzed? Please provide an explanation! Thanks :)
Answer:
a spinal injury could include pressure on the spine and swelling that puts pressure on the spinal cord and nerves which can produce paralyizing problems. also a broken disk can put pressure and block the nerve endings which may be severed to promote conduction between the nerves causing paralyizing effects.
Explanation:
Answer: A spinal cord injury (SCI) causes damage to the spinal cord in its function. Injuries can result anywhere from a simple pain to complete loss of sensation. A spinal injury can leave someone paralyzed because it is known as the brains relay system. So, if the brain can’t relay its messages to the rest of the body it May be paralyzed. One example would be T4 on the right and T6 on the left side of your body with little to no function.

• Two leak-proof bags were set up. • One bag was made from artificial partially permeable membrane (Visking tubing). • The other bag was made from a piece of small intestine containing living cells, with its inner surface inside the bag. • The bags were filled with equal volumes of a dilute glucose solution. • The bags were suspended in the same glucose solution for two hours. • After two hours, the volumes of the bags were measured and the contents were tested for the concentration of glucose. Inside the bag made from small intestine the volume and concentration of the glucose solution decreased. There were no changes to the volume and concentration in the Visking tubing bag. (c) State and explain the process responsible for the decrease in the glucose concentration in the bag made from small intestine.
Answer:
The process by which the concentration of the glucose in the bag made from small intestine decreased is aerobic respiration.
Aerobic respiration is the process by which cells breaks down glucose in the process of oxygen to release energy for their metabolic needs.
Explanation:
Living things respire, that is they break down nutrients to produce energy for metabolic activities.
The bag made from visking tubing is made of non-living materials which do not respire. Therefore, the glucose concentration in it remains constant. However, for the bag made of small intestine containing living cells, the living cells will carry out aerobic respiration using the glucose molecules found in the glucose solution. During this process, glucose is broken down in the presence of oxygen to release energy for the cells. Therefore, the glucose concentration in the bag will decrease.
How does grain used for meat production and biofuel contribute to food insecurity?
Answer:
The effects of growing biofuel demand are interwoven with tightening grain markets, which reflect demographic shifts and improved diets. In developing countries, as populations grow and incomes rise, diet preferences are shifting from staple crops to higher-value products like meat and dairy
Explanation:
The grain that should be used for production of meat and the biofuel contribute to food insecurity should be explained below.
Contribution to food insecurity:The impact of growing the demand related to the biofuel should be considered as the interwoven along with the tightening grain market that represent the demographic shifts also the diet should be improved.
