Look at the diagram below that shows the connection between the circulatory and the respiratory systems. Use the diagram to explain why pulse and breathing rates change when you exercise.
Answer:
during exercise there is an increase in physical activity and the muscle cells respire more than they do when the body is at rest
Explanation:
the heart rate increases during exercise as well as the rate of breathing, this makes sure that more oxygen is absorbed into the blood and more carbon dioxide is removed from it

ANSWER: death, loss of habitat, impacts on growth and development, and a decrease in resources.
Human have cut and frayed the woven tapestry of Earth's biodiversity. List and describe three ways.
Answer:
1. Building into the ecosystem.
2. Hunting animals for sport.
3. Increasing carbon emissions.
Explanation:
All of these are bad for Earth's biodiversity. Building into the ecosystem destroys habitats for animals, which causes the population of that species to decline. Hunting animals for sport decreases populations as well, and doesn't keep the environment in check. Increasing carbon emissions heat up the Earth, leading to colder climates warming up. This, in turn, destroys the ecosystem as well.
Anthropogenic activities and continued neglect of the ecosystem has lead to various deleterious effect on biodiversity.
What is biodiversity?It means the presence of several species of animals, microorganisms, and plants in a habitat.
What is the rivet popper hypothesis?According to this theory, the ecosystem is kept together by thousands of species, just as thousands of rivets hold together an airplane.
It may not affect flight safety at first if rivets are removed but over time, the airframe becomes dangerously weak. Similarly, species extinction in the ecosystem impairs the ecosystem's ability to function properly.
What are the three ways in which humans have affected biodiversity?Habitat loss and fragmentation: It destroys the natural habitat and niche of organisms and leads to their decline
overexploitation: It leads to depletion of the natural resources and increases the risk of extinction of endangered species.
Pollution: It destroys the quality of the habitat of organisms and creates a toxic environment which leads to the decline of species.

Group 4
Answer: From the groups stated in the attachment, the group that contains prokaryotic organisims is GROUP 1
Explanation: There are two types of cells,The eukaryotes and the prokaryotes.
The prokaryotes or prokaryotic organisms are those organisms that have just a single cell.in prokaryotic organisms,there is no presence of a distinct nucleus and it's not covered by a nuclear envelope, organelles that are bond by a cell membrane are also absent.
Prokaryotes have a cell wall that helps in the maintainance of cell shape and the prevention of dehydration because it gives an extra or added layer of protection to the cell.
The DNA,that is the genetic material of prokaryotes are not covered by a membrane,hence they move about freely in the cell cytoplasm.
Some prokaryotic organisms known as chemosynthetic prokaryotes produce their own food by getting energy and oxidizing them,these energy are gotten mainly by oxidizing high energy inorganic compounds like ammonia, hydrogen gas and sulphides.
The two types of prokaryotic organisms are Bacteria and Archaea.
This corresponds with what is given in the group 1 as seen in the attachment that came with the question.
Answer:

Crossing-over can happen at any location on homologous chromosomes. The farther apart two genes are, the more likely that crossing-over would separate them.
On these chromosomes, which pair of genes would be most likely to be separated by crossing-over: A and B, or A and C? Why?
Answer:
The answer is C I believe. Chromosomes usually make a pattern and thats the points were it would make a pattern.
~Paige~Crossing-over chromosomes.
The crossing of the chromosomes is the swap or the exchange of genetic materials. It takes place in the germline, at the formation of the egg. This is also called meiosis. It aligns with DNA sequencing. The pried chromosomes cross over the other.
Thus the answer is they make a pattern that points in the pattern.
This shows the crossing happens at the homologous chromosome. The farthest apart two genes the most likely they cross each other that would separate them. Thus the option C is correct. They cross at the end., hence is a process called recombination.Learn more about the chromosomes.

i hope it is right if not sorry!!!!!!!!!!!!!!!!!!!!!
Answer:
Aquaculture means to foster organisms (for the most part fish) that live in water.
Explanation:
After reading Holt Enviromental Science's Food and Agricultural Section: Animals and Agriculture passage, you can define aquaculture. In the passage it reads "fish farms generally consist of many individual ponds that each contain fish at a specific stage of development." The fish grow until they are matured and then "they are harvested."

What events occur during high tide
Answer:
The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. As the Earth rotates, your region of Earth passes through both of these bulges each day. When you're in one of the bulges, you experience a high tide.
Answer:
There is decrease in salinity; penetration of light to the water decreases and this is referred to as turbidity, density decreases
Explanation:
The sea is known to contain salty water as water volume increases its saltiness would decrease; the rate at which light penetrates the seas decreases; from normal science, density is Mass divided by Volume and with Mass constant and as Volume increases density is gonna increases.

Compare metamorphic rock and intrusive igneous rock in terms of how and where they form. Then compare sedimentary rock and extrusive igneous rock in terms of how and where they form.
Answer:
Igneous rock are rocks that arise from the formation of magma, as this internal terrestrial magma cools it solidifies (within the crust) forming rocks of different sizes and structures, instead metamorphic rocks are rocks formed by the modification of other pre-existing ones in the interior of the Earth through a process called metamorphism.
On the other hand, sedimentary rock is the rock that is formed by mineral sedimentation, of different minerals of large or small diameter, which compared to igneous extrusive rock, this is the solidification of magma from the earth but in the earth's crust.
Explanation:
Magma is the material that forms rocks initially, but in a liquid state, which is found inside the Earth at extremely high temperatures. When the magma rises to the surface, it cools and solidifies (consolidation) forming igneous rocks that can be internal or external depending on whether they are inside or outside the Earth's crust. On the other hand, there are other processes where rocks are formed, but not initially or primarily, but from other rocks or other minerals such as sedimentation.

What are the weaknesses or inaccuracies in the model the student created?
Answer:
The model appears to show the carbon dioxide molecules entering the blood cell and the oxygen molecules existing the cell.
Answer:
Explanation:
The model doesn’t clearly show that gas exchange happens in the alveoli through the capillaries. The model can also be easily misinterpreted. Because the model doesn’t show where this gas exchange is taking place, it looks like the blood picks up oxygen, delivers it to the body, and then comes back and expels the carbon dioxide it collects. Clarifying that this gas exchange is taking place in the capillaries would eliminate this confusion.
Provide a summary of Professor Steve Jones’ findings concerning how Natural Selection may be working today in humans.
Answer:
John Stephen Jones states that in evolution it is necessary to have into account three factors: natural selection, mutation, and random variation.
Explanation:
These three mechanisms influence evolution and they are responsible for generating phenotypic diversity that is observed in humans.

In a desert ecosystem, coyotes and rattlesnakes both eat the same type of mouse as a primary part of their diets. Recently, coyotes have been hunted and killed by people, decreasing the overall coyote population. How will this most likely affect the rattlesnake population over time?
Answer:
Answer: It will increase because coyotes are the competition.
Explanation:
An ecological niche can be defined as the functional role which an organism performs in the ecosystem in order to sustain it's life. The functional roles include how an organism obtains it's food, type of food eaten by the organism, type of habitat chosen by the organism and type of breeding season used by the organism.
In the given situation, both coyotes and rattlesnakes are dependent upon the same ecological niche that is they are dependent upon mouse as a primary part of their diets. As, both coyotes and rattlesnakes are dependent upon the same diet there may exist the competition between the two species. But it is mentioned that the coyote population is decreasing therefore the population of rattlesnake will most likely increase as the competition for the same diet decreased.

contrast homozygous and heterozygous genotypes? Dont copy from the internet please
Answer:
I got you
Explanation:
homozygous is when the letters are AA or aa NOT Aa
heterozygous is when it is Aa
The homozygous can only pass down A or a, not both. If the parent was AA, the probability of their offspring would be more likely to have a dom. phenotype is more likely. If it was aa, they are more likel to create heterozygous and recessive offspring.
The heterozygous coding is able to pass on both the recessive and dom. traits. So the offspring would be more dependent on the other parent, but most likely will have more dom. offspring.

What significant negative effect on the environment cause by obtaining water from a well?
Answer:
Some of these water-borne diseases are Typhoid, Cholera, Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria. Chemicals in the water also have negative effects on our health. Pesticides – can damage the nervous system and cause cancer because of the carbonates and organophosphates that they contain.
Explanation:
All water is a good part of the environment. ... If you mean can individuals keep getting water forever from their personal well and it has no effect on anyone else - no. It is not good in that respect. Wells are part of the local groundwater system and the water is usually not limited to one person's land.

4.The crabs that live in the aquatic biome pictured depend on living in shallow water that has a temperature no greater than 60 degrees F. If climate change causes an increase of that water’s temperature to 62 degrees F, what will likely happen to the dolphins in that biome, and why?
Answer:
The dolphins population may diminish a little.
Explanation:
Crabs are one of the many things dolphins eat, and, as the prompt suggest, they cannot live in temperature greater than 60 degrees F. If climate change makes the temperature 62 degrees F, the crab population will all die. However, note that dolphins do not only eat crabs, as they have other food sources. However, crabs are a major population, so we can see a disruption in the food web, with there being less dolphins than usual.
