Explanation:
Fish exchange gases by pulling oxygen water through their mouths and pumping it over their gills. So Basically, Its Similar to Our Lungs For us to breathe Like Fish.
Body system in humans which has a similar function to the gills in a fish is respiratory system.
What is a gill ?
A gill is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide.
What is a respiratory system ?The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants.
The primary purpose of gills and lungs in humans is to exchange gases, take oxygen in and release carbon dioxide out. Both lungs and gills have a bed of very small blood vessels with thin walls that the gases can easily travel across.To know more about respiratory system here

Write a 200-word report on your research, using proper grammar, correct spelling, and appropriate punctuation. Make sure you include:
A definition of overgrazing
A discussion on the damage overgrazing can cause
The advantages and disadvantages of each type of grazing
A discussion on the type of grazing you select to use, which includes your justification of why you selected the grazing strategy
Answer:
answer is in explanation before
Explanation:
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. Overgrazing combined with overstocking has the most damaging outcomes to the world’s natural environment. The scarcity of water resources, water pollution, degeneration of coral reefs, and eutrophication are all connected to overgrazing. The chief polluting elements include farm chemicals and animal wastes.
Types of grazing systems 1. Types of grazing systems Grazing animals (such as cattle, sheep and goats) feed on the leaves and shoots of grass... 2. Zerograzing In this type of grazing system, the animals are not allowed to go out into the pastureto graze.
Overgrazing is defined as the practice of allowing too many livestock to graze on a particular area of land for an extended period. This leads to a decrease in the vegetation cover and the soil's capacity to hold moisture, which results in soil erosion and desertification.
What is overgrazing?There are three types of grazing systems: continuous grazing, rotational grazing, and intensive grazing. Continuous grazing involves leaving livestock on a particular area of land throughout the year. Rotational grazing involves rotating livestock to different areas of land to prevent overgrazing. Intensive grazing involves keeping livestock in smaller paddocks and rotating them frequently.
Hence, overgrazing is defined as the practice of allowing too many livestock to graze on a particular area of land for an extended period. This leads to a decrease in the vegetation cover and the soil's capacity to hold moisture, which results in soil erosion and desertification.

If a population is evolving, the allele frequency ________
As a result of the experiment scientists did with Mexican tetras, it seems likely that their first hypothesis about blindness in the tetras is right. Explain how the result of the experiment supports their first hypothesis.
The scientists' first hypothesis is that blindness gives the fish some sort of evolutionary advantage, but not directly.
The experiment was: The scientists transplanted a lens from the eye of a surface tetra embryo into the eye of a cave tetra embryo. The result was striking—the surface tetra lens into the cave tetra caused all of the surrounding tissues to develop into a healthy eye.
A result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.
What is a hypothesis?An scientific hypothesis is a given explanation to a scientific observation from the real world.
A hypothesis must be verifiable, which means that it can be confirmed or rejected by using the scientific method.
In conclusion, a result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.

Water that reaches the ground and moves horizontally towards rivers, streams, and lakes is called runoff.
A. True
B. False
Answer:
A. True
Explanation:
flow off a hill slope directly to a stream in the form of runoff, or it may flows downward through the unsaturated zone to reach the water table. The area at the stream or lake to which the groundwater is flowing. Recall that water is flowing in pores where there is friction, which means it takes work to move the water.
In the mouse model of malaria, the researchers injected Plasmodium-infected human red blood cells into the mice because the Plasmodium species had surface ligand proteins that bound only to cell membrane proteins of human red blood cells. Assume that the researchers noticed that some of the parasites no longer infected human red blood cells but instead infected mouse red blood cells. Predict the most likely cause of this change in the host specificity of the parasites. Plasmodium reproduces both sexually in the host vertebrate and asexually in mosquitoes. The researchers claim that the Plasmodium organisms that infect the two different types of red blood cells are likely to evolve into two separate species of Plasmodium. Based on the biological species concept, provide reasoning that would support the researchers’ claim.

Which conclusion is supported by the fact that the black-breed boar, with its quality meat, and the white-breed sow, with its quality fertility, are swine that are often matched for mating? Animals are often paired based on physical traits and personal compatibility. Strong reproductive capability is the most important trait in animal breeding. Selective breeding combines ideal traits of animals to replicate in offspring. Swine are the only agricultural animal species that are currently crossbred.
Answer:
Selective breeding combines ideal traits of animals to replicate in offspring
Explanation:
Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.
In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.

Photoperiodism is one example of how a plant responds to changing seasonal conditions. Why is it important for plants to be able to respond to seasonal changes?
Answer:
It is important because plants respond to light depend, logically enough, on the plant's ability to sense light. Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light. Photoperiodism is the regulation of physiology or development in response to day length.

a. as a sequence of nucleotides
b. in the double helix shape of the condensed chromosome
c. in the ratio of adenines to thymines
d. as a pattern of phosphates and sugars
Answer:
b
Explanation:
Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. ... In eucaryotes, DNA is contained in the cell nucleus.
The information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Hence, option (a) is the correct answer.
Nucleic acids are of two types. They are namely deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA molecule carries the information for a specific protein. They are described as follows:
DNA is the genetic material of the cell DNA molecules undergo a process called transcription to code for codons on mRNA strand These codons tend to pair with tRNA molecule which holds the amino acids The amino acids will then form a chain in the sequence of DNA nucleotides to result in protein formationThus, we can conclude that the information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Thus, option (a) is the correct answer.
