Fatigue? (Hint: consider how the reactants of aerobic respiration get to your musde cells)
Answers
Answer: Heart strength and healthy circulatory system
Explanation:
Fatigue is considered to be the state in which a person cannot maintain the level of performance or training expected. Muscles are able to obtain energy by aerobic or anaerobic respiration and both use carbohydrates or sugars, but only aerobics needs oxygen. To perform physical activity, the heart pumps more oxygen to the muscles that are performing the exercise. When the muscles work harder, the body consumes more oxygen and produces more carbon dioxide. So, aerobic respiration is a type of metabolism in which the organism uses energy from organic molecules, especially as glucose, where the carbon is oxidized by the oxygen. 36 molecules of ATP per glucose are produced during aerobic respiration.
During an effort, the energy produced by aerobic breathing is not enough and muscles need to produce a complementary energy through anaerobic respiration which provides less energy than aerobic respiration. This type of cellular respiration produces waste products that the cells must eliminate, for example lactic acid, which remains in the muscles producing pain after exercise. Only 2 molecules of ATP are produced for each glucose during anaerobic respiration.
Therefore, the heart strength is important because that organ is responsible for carrying oxygen to the muscles, which is needed to perform cellular respiration and get more energy to perform the exercise. And there must be also a healthy circulatory system that delivers that oxygen to every part of the body.

3. Callie has brown eyes, but her husband Joseph has blue eyes. All three of their children have
brown eyes. Do you know what Callie's genotype is? If yes, what is it? If no, why not?
Help please!!
Answers
Answer:
Since Callie has brown eyes, and all her children have brown eyes, we can only assume that the phenotype of brown eyes is dominand and Callie will have a dominant genotype, leaving Joseph to have a reccesive genotype (if Joseph was heterozygous for this aspect, he would have brown eyes) and the children will be heterozygous, with brown eyes as this characteristic predominates over blue eyes.

how does tempature impact air movement?
Answers
Answer:
The heating of the earth, which in turn heats the atmosphere, is responsible for the motions and movements of the air in the atmosphere. The faster molecules move, the hotter the air. As the molecules heat and move faster, they are moving apart.
Explanation:
Answer:
As you move higher off the ground, it gets colder *and vice versa*.
Explanation:
When we move off the ground, density is pulled down to the ground due to gravity. Therefore, it gets colder. It's also because of our atmosphere. (Vice versa, of course)
P.S. Density and gravity are also key parts of climate change, keep that in mind.
Which scientists played a role in developing the cell theory?
A Charles Darwin
B Theodor Schwann
C Robert Remak
D Robert Hooke
E Matthias Schleiden
Answers
So the answer might be E and B
The scientists that played a significant role in developing the cell theory are Theodor Schwann and Matthias Schleiden. Thus, the correct options are B and E.
What is Cell theory?Cell theory was proposed by a German botanist M.J. Schleiden and a German zoologist T. Schwann. According to them, the cell theory states that:
All living organisms whether it is plant or animal is made up of cell.A cell is the smallest unit of all living organisms.The Cell is the structural and functional unit of organisms.Charles Darwin was popular in the field of evolution. Hence, he is referred to as the father of evolution. Robert Hook was known in order to discover a cell in 1665.
Later in 1855, the cell theory is further refined by German biologist R. Virchow. According to him, all cells are arising from pre-existing cells.
Therefore, the scientists that played a significant role in developing the cell theory are Theodor Schwann and Matthias Schleiden. Thus, the correct options are B and E.

Which is endocrine function?
A. Pyloric glands release mucus to the stomach
B. Adrenal glands release adrenaline into the blood.
C. Esophageal glands release mucus into the esophagus
D. Salivary glands release saliva into the mouth
Answers
Answer:B. Adrenal glands release adrenaline into the blood.
Explanation:
The adrenal glands are small glands located on top of each kidney. They produce hormones that you can't live without, including sex hormones and cortisol. Cortisol helps you respond to stress and has many other important functions. With adrenal gland disorders, your glands make too much or not enough hormones
Adrenal glands are a type of endocrine glands that release hormones that include adrenaline into the blood. Thus, the correct option is B
Endocrine glands secrete their products directly in the surrounding interstitial fluid or blood, and not through ducts.
Adrenal glands are a pair of endocrine glands that are present superior to each kidney. It comprises of two distinct regions - adrenal cortex and adrenal medulla.
Adrenal cortex is the outer region of the adrenal gland that produces and secretes hormones like mineralocorticoids, glucocorticoids and androgens.
Adrenal medulla is the inner region of the adrenal gland and produces and secretes the hormones adrenaline and noradrenaline.

D. As the deer population reached a maximum so did the carrying capacity. As the deer population decreased, so did the
carrying capacity until the environment stabilized and the deer population could increase again.

C seems to be the most reasonable answer.
Explanation:
The graph depicts that in an ecosystem the deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there was less food available, reducing the carrying capacity.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Review why carbon can form a variety of organic compounds in a variety of shapes.
Answers
Answer:
Carbon atoms readily bond with each other and can form long chains, branched molecules, and rings—an enormous variety of carbon backbones for organic molecules.
Explanation:
Carbon atoms easily connect with one another, allowing for the formation of lengthy chains, branching molecules, and rings—a vast array of carbon backbones for organic molecules.
What is carbon?Carbon is defined as the elements are distinguished by their capacity to form firmly bound chains that are sealed off by hydrogen atoms.
Carbon is also defined as an atomic number 6 chemical element with the symbol C.
Carbon is nonmetallic and tetravalent, with each atom releasing four electrons to form covalent chemical connections.
Carbon has the capacity to quickly form bonds with other atoms, which allows for greater flexibility in the shape and function of biomolecules such as DNA and RNA, which are required for the defining traits of life growth and replication.
An organic molecule is defined as a complex molecule composed mostly of carbon atoms that are bound with other elements and/or other carbon atoms.
Carbohydrate, lipids, nucleic acid and protein are some of the example of organic molecules.
