Answer:
Adenine (A) = 28%
Cytosine (C) = 22%
Explanation:
The DNA molecule, which is the genetic material that stores or holds information needed by the cell for growth, reproduction etc. Structurally, the DNA is composed of nucleotide subunits, which are of four types namely; Adenine, Guanine, Cytosine, and Thymine etc.
According to Chargaff in his complementary base pairing rule, he states that Adenine will always pair with Thymine (A-T) while Guanine will always pair with Cytosine (G-C). Based on this, Chargaff further stated that the amount of adenine must be equal with that of thymine while that of guanine must be equal to cytosine.
In total, their total amount must be equal to 1 or 100% i.e. (A + T) + (G + C) = 100%. In this question, 22% of Guanine are found in the DNA of a fox. This means that automatically, the percentage of cytosine is 22%. We then calculate the amount of Adenine and Thymine as follows:
(A + T) + (G + C) = 100%
A + T + 22 + 22 = 100
A + T + 44 = 100
A + T = 100 - 44
A + T = 56
Since A = T,
56/2 = 28
Hence, A = 28%, T = 28%
Which of the following statements is FALSE regarding the effects of exercise on metabolism and body composition? Group of answer choices It slightly raises the metabolic rate for several hours after exercise. The increase in muscle mass raises the metabolic rate. It increases caloric expenditure and thus helps regulate body weight. It can result in substantial weight gain due to increase in muscle mass.
Answer: The false statement regarding the effect of exercise on metabolism and body composition is that (It can result in substantial weight gain due to increase in muscle mass).
Explanation:
Metabolism of the body simply means all the chemical reactions in all the cells of the body and the metabolic rate is normally expressed in terms of the rate of heat liberation during chemical reactions or physical activities.
The body composition of healthy adults who maintain stable body weight, energy intake is balanced with energy output. Energy output includes energy used for:
--> performing essential metabolic functions of the body.
--> performing various physical activities (exercise)
--> digesting, absorbing and processing food.
--> maintaining body temperature.
When an individual performs exercise, the rate at which heat is liberated( metabolic rate) is increased. This is because ATP which is gotten from the food is used as energy during exercise and is converted to heat as the end product.
Also, increase in muscle mass raises the metabolic rate because the more muscle in the body, the more calories are used up during rest and therefore the higher your metabolic rate.
Therefore the statement is false about the effects of exercise on metabolism and body composition because exercise involves energy output cannot lead to SUBSTANTIAL weight gain even in increased muscle mass.

pictured below?
support and movement of the skeleton
movement of food through the digestive system
contraction and relaxation of the heart
generation and conduction of electrical signals
Answer:
These are striated skeletal muscles.
Explanation:
support and movement. There is an attachment to the skeleton to help move limbs, usually connected from bone to limbs..cross striations with dark A bands & light I bands. The Z line stands out in the center of I bands...hope this helps..
These muscles are striated which help in supporting and assisting the skeleton's movement. So, the correct option is A.
What are striated muscles?Highly organised tissues called striated muscles are responsible for converting chemical energy into muscular work. Striated muscles have two main purposes: to pump blood through the body (cardiac muscle) and to produce force and contract in support of breathing, movement, and posture (skeletal muscle).
They have striations, which are alternate bands of light or dark. The muscles of the face, the neck, limbs, etc. contain striated muscles. Additionally, the pharynx, tongue, diaphragm, the upper part of the esophagus all contain them. In the given example, these muscles are striated which help in supporting and assisting the skeleton's movement.
Therefore, the correct option is A.

describe what is happening at each phase of meiosis
The process of meiosis takes place in two phases. Meiosis I; Meiosis II; Phases of Meiosis 1 and Meiosis 2. During meiosis I, a cell is divided into two, and in meiosis II, further division takes place, resulting in a total of four haploid cells. Before the start of the process, the parent cell goes through a stage of preparation called the interphase.

document to help you with this project.
Using your research, you should be able to answer these questions:
1. What are genetically modified foods?
2. What crops are typically genetically modified?
3. Why are crops genetically modified?
4. How are crops genetically modified?
5. How do genetically modified foods affect society and the environment?
You will then share what you have learned by preparing a multimedia presentation. Your multimedia
presentation should include a title slide, a number of content slides that include specific information about
genetically modified foods, and a slide that lists the sources you used in your research.
Answer:
Genetically modified foods, also known as genetically engineered foods, or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.
The most common GMO crops include soybean, maize, cotton, canola, and alfalfa. The following GMO crops were also planted in different countries in 2018: papaya, eggplant, potato, apple, safflower, pineapple, and sugarcane.
For centuries, farmers have bred crops for certain desirable traits. Genetically Modified (GM) crops offer improved yields, enhanced nutritional value, longer shelf life, and resistance to drought, frost, or insect pests.
Genetic modification of plants involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics. ... The gene of interest is transferred into the bacterium and the bacterial cells then transfer the new DNA to the genome of the plant cells
GMOs have helped farmers reduce their environmental footprint by allowing them to use fewer inputs and enabling a shift to reduced tillage. These practices have led to less time spent on a tractor, less fuel used and fewer emissions.

Explanation:
Answer:
nucleus
Explanation:
The nucleus contains most of the DNA in a cell and this DNA is called the chromosomal DNA it is separated from the rest of the cell (cytoplasm) by a double layer of membrane.
What is the defining feature of lipids?
O They are can be either polar or nonpolar, depending on the nitrogen-containing functional group attached.
O They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.
O They are largely polar because they consist of mostly polar glycosidic bonds.
Answer:
O They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.
Explanation:
Lipids do not contain nitrogen groups and do not have polar glycosidic bonds. In addition, the function of cellular membranes depend greatly on the fact that lipids (phospholipid bilayers) are polar!
The defining feature of lipids is- option. They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.
Lipid is a micro biomolecule that is made up of fatty acids or their derivatives. These are molecules that are soluble in nonpolar solvents and insoluble in water.
Lipids are largely nonpolar in nature.The nonpolar nature is due to consisting mostly nonpolar carbon-carbon or carbon-hydrogen bonds.Non-polar molecules are hydrophobic therefore, lipids also insoluble in water. Lipids help in many cellular processes and parts of cell structure such as cell membrane.Thus, the correct answer would be the option. They are largely nonpolar because they consist of mostly non-polar C-C and C-H bonds.

Which of the following is NOT a reactant of photosynthesis?
a. Carbon dioxide b. Water c. Oxygen d. Light
Photosynthesis produces both glucose (sugar) and oxygen as products in the chemical reaction. Plants use photosynthesis to take in sunlight, water, and carbon dioxide as reactants and produce glucose for energy and oxygen. The reactants for photosynthesis are light energy, water, carbon dioxide and chlorophyll , while the products are glucose (sugar), oxygen and water.
I hope this helps =)
Considering the definition of photosynthesis, oxygen is not a reactant needed for photosynthesis.
But first it is neccesary to know that photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.
Taking as examples plants, first water and minerals are absorbed from the environment, generally through their roots, then the absorbed nutrients circulate through the plant to the leaves, which is where photosynthesis will almost always take place.
For the photosynthesis of plants to take place, the presence of chlorophyll is necessary, a pigment that is sensitive to sunlight and is the one that gives plants their characteristic green color.
Chlorophyll has the ability to absorb energy from sunlight and transfer it to the production (synthesis) of carbohydrates from two compounds available in the medium: water (H₂O) and carbon dioxide (CO₂) (captured from the environment).
This photochemical process also produces oxygen (O₂) that is released into the atmosphere.
Finally, synthesized organic molecules can be used as a source of chemical energy to support vital processes such as cellular respiration and metabolism.
Then, sunlight, carbon dioxide and water are needed for the photosyntesis, while oxygen is released to the environment.
This is sunlight, carbon dioxide and water are reactants needed for photosyntesis, and oxygen is not a reactant needed.
