Answer:
A. Each channel only allows one type of molecule to pass through it
Explanation:
Transmembrane proteins from channels spanning the membrane that create hydrophilic tunnels. They only enable diffusion across the protein channel into the cell, for their target molecules.
These are highly specific-they only allow one type or group of related molecules to use the channel. These are types of transmembrane channels, embedded within the membrane, help to maintain selective permeability, while simple diffusion of other small, uncharged molecules can readily occur.

6. D. It breaks down glucose to form ATP.
7. D. All autotrophs are producers
8. D. All 4 statements are correct.
9. False
10. False
Explanation:
The process of photosynthesis converts carbon dioxide and water into glucose and oxygen while the in the process of cellular respiration, glucose and oxygen are converted to water and carbon dioxide and ATP is formed.
In photosynthesis, glucose is formed while in cellular respiration ATP is formed. The process of forming ATP and glucose are ways in which energy is cycled and oxygen cycle occur in the atmosphere. Energy can not be recycled but it is rather used. Only green plants carry out photosynthesis. Autotrophs are known to be primary producers.
What is the role of lactase? which sugar does the act on in reaction?
Answer:
This enzyme helps to digest lactose, a sugar found in milk and other dairy products. Lactase is produced by cells that line the walls of the small intestine. ... Lactase functions at the brush border to break down lactose into smaller sugars called glucose and galactose for absorption.
Explanation:
Lactase is an enzyme produced by many organisms. It is located in the brush border of the small intestine of humans and other mammals. Lactase is essential to the complete digestion of whole milk; it breaks down lactose, a sugar which gives milk its sweetness.
What might happen in this ecosystem if the fox was removed?
Answer:
The numbers of rat will increase & fox eaters will decrease in ecosystem
If the fox was removed from the ecosystem, the number of primary consumers i.e, herbivore may increase drastically that will cause heavy loss to vegetation.
What is the importance of foxes?Foxes being the most widely distributed canine on diverse habitats of earth. Regardless of significant member of secondary consumers, foxes are important indicators of food web stability and hospitable terrain wherever they live.
Red foxes help to hold control on rodent and rabbit populations, which causes heavy loss to vegetation if present in greater number.
Foxes also may assist in seed dispersal by eating fruits and their fur adhere seed to be carried where they navigate.
Thus, if the foxes are removed from the ecosystem, it will negatively impact the ecosystem by imbalancing the food web.

Number of chromosomes?
Sex of individual?
Normal? Yes or no.
If abnormal, what chromosome pair?
This is the picture of karyotype. Karyotype is a collection of a Individuals chromosome. Like pairs are separately represented from the unlike pairs, It is generally used to study the chromosomes and the abnormalities found in the number of chromosomes.
_____________________________________CHROMOSOMAL NUMBER 18:Every chromosomal pair seems fine, except the chromosomal pair number 18. Because as you ca see that it has 3 chromosomes instead of 2. This impairment in the chromosomal pair is called trisomy as it has 3 chromosomes.
_____________________________________TRISOMY 18:Trisomy 18 is also called Edwards syndrome. It is a chromosomal condition associated with abnormalities in more than one part of the body. Individuals with trisomy 18 often mature slowly than normal fetus before birth and they have lower weight at the time of birth as compared to the other children.
_____________________________________Best Regards!'Borz'There are 23 pairs of chromosomes in total, and the individual is male because it has one X and two Y chromosomes, but this individual is abnormal because of the trisomy in the 18th chromosome, as the 18th pair has three chromosomes.
What is the chromosomal abnormality?The chromosomal abnormality is caused by the mutation in the chromosome number and includes either the deletion of the chromosome or the addition of the chromosome in a homologous pair. The chromosomal abnormality has many negative consequences as well, some extra copies in the sex chromosome pair cause infertility, etc., while deletion causes life-threatening conditions.
Hence, there are 23 pairs of chromosomes in total, and the individual is male because it has one X and two Y chromosomes, but this individual is abnormal because of the trisomy in the 18th chromosome, as the 18th pair has three chromosomes.

Explanation:
Which of these organisms would most likely be found at the top of an energy pyramid?
a clams - a primary consumer
b. sardines - a primary consumer
c. sharks - a secondary consumer
d. kelp - a primary producer
The energy pyramid is a diagram that shows the flow of energy between trophic levels in an ecosystem. In an energy pyramid, the energy flows from producers to consumers.
The organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).In an energy pyramid, the energy flows from producers (e.g., plants) to primary consumers (eg., herbivores). Subsequently, the energy then flows from primary consumers to secondary consumers (e.g., carnivores) and so successively.In an energy pyramid, the amount of available energy decreases as it moves through subsequent trophic levels.In conclusion, the organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).

describe the effects that enzymes can have on substrates
Answer:
Enzymes bind with chemical reactants called substrates there may be one or more substrates for each type of enzyme I beleivedepending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products the enzyme's active site binds to the substrate.
Explanation:
Hope this helps.
Answer:
When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process

What is the definition of erosion in rock biology?
Answer:
Erosion is the process where rocks are broken down by natural forces such as wind or water. There are two main types of erosion: chemical and physical.Describe the path that energy takes, from solar energy reaching earths surface to energy used to power cell processes in animals
The path that energy takes, from solar energy reaching the earth's surface to energy used to power cell processes in animals - Animals eat the grass that captures the energy from the sun which gives the animal nutrients
The Sun is the primary source of energy for organisms and the ecosystems of which they are part.
Producers, such as plants and algae, get their energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter.This process begins the flow of energy through almost all food webs.The energy present in these photosynthetic organisms store then transferred to various animals when they feed on these plants and algae and get their food and energy.Thus, the correct answer would be - Animals eat the grass that captures the energy from the sun which gives the animal nutrients

After reading the paragraph below, answer the question that follows.Scientists interested in knowing the best way to restore an area after a temporary road was built through it completed a study comparing two treatments: (1) restoring the contour of an area so that there was no longer a depression or cut-through where the road was previously and (2) simply abandoning the area to allow vegetation to return on its own. They wanted to know whether either or both of these treatments would return the aboveground vegetation and the belowground soil properties to their original state, as seen in a similar area where there had never been a road.In this experiment, the area that had never had a road is useful to the experiment because:________________
Answer:
it acts as the control group in the experiment
Explanation:
The area that had never had a road is extremely useful because it acts as the control group in the experiment. The researchers can use this untouched area of land as a benchmark for the rest of the experiment. Once they implement both test scenarios on the pieces of road, they can then compare the results gathered from each study with the data gathered from the area that had never been a road in order to determine which option provides results that best compare to the original properties of the piece of area that has never been made into a road.
