What is a function of the backbone in animals?
A. It protects against predators.
B. It regulates blood glucose.
C. It surrounds the spinal cord.
D. It limits movement.
Answer:
C>
Explanation:
just took the test hope it works.
The main function of the backbone in animals is that It surrounds the spinal cord. Vertebrate bodies are supported structurally by their backbones, hence option C is correct.
How backbone is important in animals?The vertebral column's main job is to protect the spinal cord, but it also stiffens the body and serves as an attachment point for several muscles, the pectoral and pelvic girdles, and the spinal cord.
In contrast to cartilaginous or bony vertebrates, any animal without a vertebral column, or backbone, is referred to as an invertebrate. Invertebrates make up more than 90% of all species of living animals.
Therefore, the vertebral arch, also known as the bony arch on the back of a vertebra that surrounds the spinal cord, is made up of the spinous process and lamina.

B.
separation of powers and eminent domain
C

D.
separation of powers and quartering of troops
Answer:
A, Checks and balances and separation of powers.
Explanation:
Answer:
The correct answer is:
checks and balances and separation of powers
Explanation:
The system of checks and balances refers to instances in which the powers of the branches of government overlap, such as the Executive and the Legislative branch both having some power over the acts passed by Congress. Separation of Powers refers to instances in which separate branches have completely separate responsibilities, as in creating, interpreting, and enforcing the laws. Both of these doctrines are in place to ensure no branch gains too much power.

inhalation?
Larynx
D
Pharynx
C
Lung
B

Answer:
Lung
Explanation:
Lungs expand to pull oxygen into the body and contract to push it back out. The larynx is known as the voice box which is an air way passage to the lungs and a pharanx is membrane lined cavity behind the nose and mouth. Neither of these really expand or contact during inhalation so the answer is Lungs.

Photosynthesis
Answer:
Output: Respiration as the CO2 absorbed during photosynthesis is returned to the atmosphere, during respiration; carbon is given off .
Acid rain, as formation of carbonic acid, is output of carbon. This is because,the carbonic acids is swept into the oceans together with silicon elements in rocks, and deposited in marine carbonates sediments adding to the carbon contents.
In addition the carbonic acid formation as circulation ocean ocean surface water, absorbs more atmospheric CO2 as it cools near the poles.Thus adding to the Carbon contents.
Inputs.
Decomposition of life forms ,where Carbon in plants and animals are converted to CO2 (by bacterial and fungi)in presence of oxygen and in absence to methane.
Input :Combustion oxidizes carbon stored as organic matter when subjected to heat to produce CO2.
CO2, in dissolve form is input into the atmosphere from the surface of the ocean water,

3. A. How is active
transport different from passive transport?
3. B. What are transport proteins?
3. C. Explain why transport proteins
require energy to function in active
transport.
Answer:
1. Water(solvent) molecules travel from A across the cell membrane / semi permeable membrane to B until the concentrations of A and B become equal.2. Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.3. A transport protein is a protein that serves the function of moving other materials within an organism.
4. Active transport is the movement of materials through a cell membrane using cell membrane using cellular energy. ... transport proteins requires energy to function because it needs energy then passive transport that requires no energy at all.

If I study light and dark peppered moths in light and dark environments what would be the test variable and the outcome variable?
Answer:
the independent (test) variable is the physical changes (studying in the light or the dark) and the dependent (outcome) variable would be whatever you are trying to study (I assume it is the behavior of the moths)
Explanation:
the test variable is the variable you change during the experimental process and the outcome variable is what would be directly effected by the change in the experiment.
Test Variable--- changing the amount of light
Outcome Variable--- the effect it has on the moths

Examine the picture of an onion root tip with cells in various stages of the cell cycle. A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why. A) Mitosis is the longest stage because anaphase requires more time to separate chromatids. B) Interphase is the longest stage because chromosomes are visible in the majority of the cells. C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA. D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing.
Answer:
B
Explanation:
the longest phase in the cell division is interphase because the DNA replication occurs in this phase
As per the image interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing. The correct option is D.
What is cell cycle?The cell cycle, also known as the cell-division cycle, is the sequence of events that occurs in a cell that causes it to divide into two daughter cells.
A cell cycle is the series of events that takes place in a cell as it grows as well as divides.
A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.
Interphase is the longest stage, according to the image, since the maximum of the cells in the photo have uncondensed chromatin as well as are not dividing.
Thus, the correct option is D.

Which of these is true of fetal development by the end of the third trimester?
A. The placenta is absorbed by the uterus.
B. The fetus can survive outside the uterus.
c. All development is complete.
D. All growth is complete.
Answer:
B. The fetus can survive outside the uterus.
Explanation:
The third trimester starts in the wekk 28 (month 7 ) of fetal development and lasts until the birth pf baby, that is around week 40 (month 9) of pregnancy.
There are several changes occur in the thrid trimester of the fetal development such as hearing and visual has developed and the internal organs including the heart, lungs, intestines and stomach has developed enough.
So, at the end of fetal development of the third trimester as all the body organs have grown and developed, a fetus can survive outside the uterus.
The correct option is B.
Answer:
Option B
Explanation:
During the third trimester, the fetus continues to grow in weight and size however the body systems finish maturing. In fact, both mother’s body and the fetus continue to grow and change. Lungs, brain and kidneys keep maturing. Fetus position itself head-down and is 6 to 9 pounds in weight. Skull bones are soft but fetus become able to suck its thumb and cry. By 38 to 40 weeks, the lungs have matured fully . The end of third trimester marks the period when the fetus is ready for delivery. Hence option B is the correct answer
