Answer:
Your answer would be "B) They pass oxygen from the air into the blood."
Explanation:
They certainly don't coordinate the movement of the heart, so A isn't an option.
The lungs also don't pump blood through the body, that's the hearts job.
And the lungs do not filter carbon out of the air, which eliminates D.
Therefore your answer is B.
The lungs function in the human body by passing oxygen from the air into the blood.
Gaseous exchange in the lungGaseous exchange happens in the lung of humans. Oxygen is exchanged for carbon dioxide.
A mixture of air is taken through the mouth and the nose into the lung. On getting to the lung, the oxygen in the air dissolves on the surface of the lung and enters the blood by diffusion.
In exchange, carbon dioxide in the blood diffuses in the opposite direction and is breathed out.

Explanation:
9- The results of this type of DNA analysis are often used to help
determine *
A) the number of DNA molecules in an organism
B) if two species are closely related
the number of mRNA molecules in DNA
OD) if two organisms contain carbohydrate molecules
Answer:
B) if two species are closely related.
Explanation:
DNA analysis is used to determine the relationship between two species in order to check their relations with each other because DNA molecules has all the information about the organisms. If there is more similarities between two organisms so they are more closely related to each other while on the other hand, if there is no similarities between two species so we can say that there is no relationship exists between two organisms or species. All this discussion describes the usefulness of DNA analysis.

Moves so that the concentration of water on one side of the cell membrane is higher than on the other side d. Moves until there is no water left on one side of the cell membrane
Apply Concepts Eventually, most people with Alzheimer's disease lose the ability to recognize common objects. Explain which lobe is affected at this point in the disease
Answer:
The right temporal lobe
Explanation:
The cerebral cortex of the brain has two sections known as hemispheres, and each hemisphere can be divided into four lobes: frontal, parietal, temporal and occipital. Alzheimer's disease is the most common cause of dementia, which is characterized by the damage of the temporal lobe. Alzheimer’s disease usually initiates in the hippocampus, which is a structure inside each temporal lobe. The temporal lobes are involved in different neuronal functions: object recognition, face recognition, perception, memory, language, emotions, etc. The right temporal lobe is mainly involved in processing visual information (i.e., face recognition, object recognition, familiar recognition).

Answer:
C. Xylem transport water and nutrients from the soil to the leaves while phloem transport carbohydrates from the leaves to the rest of the plant.
Explanation:
write two examples of consumers tell whether they are herbivores omnivores carnivors or scavengers
Answers
Lion,Tiger -Carnivores
vulture- scavenger
Cow,sheep -Herbivores
Man, Pig -Omnivores
In an ecosystem, consumers are organisms that obtain their energy and nutrients by feeding on other organisms. They are a vital part of the food chain, and they come in different sizes and types.
Consumers can be classified into several categories based on what they eat. For example:
Herbivores: These are animals that consume only plants for their food. Examples include rabbits, cows, and giraffes.Carnivores: These are animals that consume other animals for their food. Examples include lions, tigers, and sharks.Omnivores: These are animals that eat both plants and animals. Examples include humans, bears, and raccoons.Scavengers: These are animals that feed on the remains of dead organisms. Examples include vultures, hyenas, and some types of beetles.Consumers play an important role in an ecosystem, as they help to transfer energy and nutrients from one level of the food chain to another. They are an integral part of maintaining the balance and stability of an ecosystem.

You are a mad scientist. You have figured out a way to replace one part of the respiratory and circulatory systems. You believe by doing this one thing you can create an army of physically unbeatable warriors and conquer the world. (Remember you are MAD!) a - What part would you replace to accomplish this? b - What would you replace it with? c - Explain your thinking on how doing this would help create these powerful warriors.
Answer:
I'd proceed to order pipes from ebay as to replace said parts.
During the process I'd question why is there an army of beef-cake Mega-Men in my basement.

What type of speciation occurred in the fish?
A. allopatric
B. peripatric
C. parapatric
D. sympatric
Answer:
A. allopatric
Explanation:
Allopatric speciation consists of the geographic separation of a continuous genetic background -population-, giving place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate individuals, or geological events. In this type of speciation, some barriers impede genetic interchange or flow. The populations are separated by a barrier and can not get together and mate anymore. These barriers might be geographical or ecological.
When a geographical barrier emerges, this is known as a vicariant event. Vicariance is the geographical separation of a population imposed by discontinuities in the physical environment that divides populations that originally were continuous. The process of vicariant allopatric speciation involves different steps:
• The emergence of the barrier.
• Interruption in the genetic interchange
• The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
• Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
• Prezigotic isolation mechanisms favored by selection once a secondary contact between the new formating species occurs.
So in the exposed example, the original population was composed of fishes living in a pond under the same environmental conditions and selective pressures.
However, with time, the pond dried, causing a decrease in water level and the emergence of a new physical barrier. The original population got separated by a piece of ground, and the original pond turned into two smaller ponds. The physical barrier is now interrupting the genetic flow between both groups.
Animals on each pond suffer from different environmental pressures to which they need to adapt. New mutations occur, leading to genetic divergence between the two separated groups. Two species emerged, red fishes and blue fishes.

The herbivores in the forest don’t consume this low-growing invasive plant because they mistake it for a similarly shaped toxic plant in the forest. The invasive plant needs a lot of room to grow. It sprouts from its seeds much earlier than the native species. What effect can its growth have on the native herbivores’ food supply?
Answer:
It could grow at such an extrem erate that it could use up all natural resources that the native species needs to survive. thus breeding out all native species and becoming a invasive species. The native species the animals eat now does not exist and the animals that needed that food will decrease drastically in populus.
