Choose one of the following three diagrams. Specify your choice here:__________ (a, b, or c). Identify the system(s) your diagram represents, and the parts associated with that system.

Answers

Answer 1

Answer:

b. Motor Unit

Explanation:

A motor unit is consist of motor neuron and muscles fibers connected through the axon terminal of neuron. Motor unit function for the movement (contraction and relaxation) of muscles.

A neuron is connected with muscles fiber through the axon terminal of neuron and is called neuromuscular junction. Skeletal muscle fiber is consist of a cylindrical muscle cell that contain microfibrils which participate in contraction and relaxation of muscles.

Neuron and muscle fiber coordinate with other other for the proper functioning of motor unit.

Hence, I selected diagram "b" that represents motor unit.

How does the double helix structure of DNA explain how the molecules can be copied or replicated

Answers

Answer:

How does the double-helical structure of DNA explain how the molecules can be copied or replicated? Because of base pairing, each strand has all the information to serve as a template for the other strand. DNA replication occurs only during the S phase of the cell cycle.

Explanation:

Because of base pairing, each strand has all the information to serve as a template for the other strand. DNA replication occurs only during the S phase of the cell cycle.

What is DNA?

Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.

The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a tiny quantity of DNA in the mitochondria (where it is called mitochondrial DNA or mtDNA). Cellular organelles called mitochondria transform the energy from food into a form that can be utilized by cells.

Adenine (A), guanine (G), cytosine (C), and thymine (C) are the four chemical bases that make up the code that stores the information in DNA (T).

Therefore, Because of base pairing, each strand has all the information to serve as a template for the other strand. DNA replication occurs only during the S phase of the cell cycle.

Match each digestive juice or enzyme to the organ where it performs.

-hydrochloric acid
-saliva
-pancreatic juices

Answers

Answer:

-saliva

-hydrochloric acid

-pancreatic juices

Explanation:

When the food such as carbohydrates enters our mouth, the saliva enzyme starts break down of that carbohydrate. Then the food enters the esophagus and then reaches the stomach. In stomach, hydrochloric acid is present which helps in digestion of food. Then the food enters the small intestine and their pancreatic juice is present which also helps in break down of sugars, fats, and starches.

Phylogeny can be based on morphological homologies and molecular homologies. What are the advantages and limitations to using each

Answers

Answer:

1. Molecular data:

- Advantages:

a. less susceptible to evolutionary convergence

b. huge amount of potential characters available for data comparison (each nucleotide can potentially be used to assess the state of a character)

c. useful for assessing times of divergence

- Disadvantages:

a. multiple sequence alignments are hard to solve for sequences with high evolutionary rates

b. limitation to the number of states of the character

c. generally unuseful for comparing with data from extinct species

d. difficulties of inferring positional homology

2. Morphological data:

- Advantages:

a. useful to understand the evolutionary significance of traits in extinct ancestral species

b. there is not limitation to the number of different states of the character

- Disadvantages:

a. susceptible to evolutionary convergence

b. limited number of characters is available

Explanation:

Morphological and molecular data are the two primary sources of information used to infer homology. In the last years, molecular data gained ground for this purpose. However, it should be stressed that molecular data only have 4 different states (i.e., 4 different types of nucleotides), while for morphological data in principle there is not limitation to the number of different states. On the other hand, morphological traits are more susceptible to evolutionary convergence, thereby leading to spurious results when assessing the homology of problematic characters. Finally, it is important to highlight that morphological data are generally more useful to understand the origin and homology of traits in extinct species.

A response is a “reply” or a “reaction.” Use this information to explain why the health damage that results after exposure to a harmful chemical is called a response.

Answers

a response to exposure would mean that your body is reacting to the harmful chemical. when your health is at stake, your body reacts with a response. for example, if you get a chemical in your eye, you start tearing up and your eye turns red. that's a response to the chemical.

A chemical substance is a stimulus which produces a response or reply in the body.

What is a stimulus?

A stimulus is a factor or agent that produces a response in the body of a living organism.

When a stimulus is received by the body, it produces a response.

A harmful chemical that is introduced to the body is a stimulus which could cause damage to the body.

The response the body produces to the chemical substance would be to help the body recover.

Therefore, a chemical substance is a stimulus which produces a response or reply in the body.

The mother is a carrier for hemophilia and since the disease is sex linked and found on the X chromosome, only one of the alleles has that H allele attached to it. The father is male so he only has one X chromosome, which is why he is effected by the disease and not just a carrier like the mother.

24. Fill in the blanks. An enzyme is made up of _____. Enzymes can

Answers

enzymes are made of strings of amino acids chemically bonded to one another. These bonds give each enzyme a unique structure, which determines its function. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases.
