B is higher than that in Solution A. Describe
how the water molecules will move.
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.

Which structure in the diagram below is a muscle that contracts during
inhalation?
Larynx
D
Pharynx
C
Lung
B
А
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,

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.

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

When there are high levels of carbon dioxide in the respiratory system, the blood pH level
A. decreases, increase
B. decreases, decrease
C. increases, decrease
D. increases, increase
Answer:
A) Decreases;increase
Explanation:
When there are high levels of carbon dioxide in the respiratory system, the blood pH level decreases, causing respiratory rate to increase.
This condition is acidosis because not enough CO2 escapes lungs hence CO2 accumulates and decreases pH of blood, making it more acidic. As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing to increase the amount of carbon dioxide exhaled to bring our body to the ideal pH.
