Answer:
One million.
Explanation:
Each kidney contains about one million of nephrons. The nephron is the structural and functional unit of the kidney means that our kidney is made up of nephrons. The main function of nephron is to produces urine in the process of removing waste, toxic and excess substances from the blood. kidney is responsible for the filtration of blood by removing all the waste materials and taken these waste materials to the excretory organs in order to remove from the body.

Which organism shown in the diagram serves as the foundation, or base, for the food web?
hawks
snakes

chickadees
the base would be the beginning of a thing right?
and if it is then plants would be the base
but if it's not then I'm sorry,
but if it's the thing that all the things can eat (except plants) then maybe lizards
srry if I'm wrong ;-;
Organisms that live in the tundra have developed unique adaptations that aid in their survival. Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. It is the largest terrestrial carnivore, but it is also an excellent swimmer that spends much of its time in and near the water hunting its favorite food. It has large paws with small bumps to provide traction as it walks across the ice. Its fur is helpful as camouflage during the winter months, but not as helpful during the summer. Which organism has the adaptations described that enable it to survive in the tundra
Answer: The organism that has the adaptations described that enable it to survive in the tundra is the POLAR BEAR.
Explanation:
ADAPTATION is defined as the process by which an organism becomes fitted to its environment thereby enabling the organism to live successfully and reproduce.
In any population, an organism is able to survive if it has features that help them to fit and compete successfully in that environment.
From the question, a typical example was given concerning the POLAR BEAR (Ursus maritimus) and it's best fitted environment which is the tundra.
The tundra is a type of biome that is treeless marshy vegetation which is composed mainly of dwarf shrubs. It's has a cold climate (Arctic region) with long icy winters and very short summer with an average temperature of 10°C.
Ursus maritimus has a variety of adaptations which enable it to survive in the tundra. These adaptations include:
--> The presence of a thick coat of insulated WHITE FUR: this helps it to survive the cold environment by acting as an effective insulator. The fur is also found at the base of its large paws with small bumps, which protects it against cold surfaces and provides its with a better grip of ice as it walks across it. It also gives it a concealing coloration making it unnoticed while it stalks its prey in the snow. These are the features that enables it survive the terrestrial environment if tundra.
--> it also has some aquatic adaptations which enables it to hunt it's favourite food which is seals. The presence of large front paws which are slightly webbed allows them swim for a long distance in search of food.

Summarize What adaptations do cephalopods have to live an active way of life?
Answer:
The answer is below
Explanation:
The adaptations that cephalopods have, to live an active way of life are numerous, some of which are:
1. Development of a SIPHON. This is a form of the adapted foot that supports survival such as swimming and directional movement.
2. A powerful and flexible arm for movement and protection
3. Using ink to form visual distractions, against predators.
Note that a good example of cephalopods are known as octopus

In your own words, describe how the time required for digestion can be used to determine the time of death.
Answer: Backdating the time required for food found in the stomach of the deceased to digest. Since digestion can't continue after death.
Explanation: The time taken for food to get digested can be employed to depicts time of death. This process involves understanding the period of time that usually takes the food found in the gastric of the deceased to calculate the time of death.
Different foods has varying time of digestion, so therefore, the gastric content is a good indicator to determine time of death by the doctor who is carrying out autopsy, since digestion does not continue after death.
However, it is established by scientist that food takes up to 4-6hours in the stomach depending on the size and type of food. Hence, if the status of the food found in the deceased stomach is noted accordingly and the time taken requires for digestion is also noted، the doctor can deduce the time of death accordingly from this two points.

Algae possess chlorophyll in their cells. They use carbon dioxide in a manner that is analogous to how we use food. Thus, option B is correct.
What is a characteristic feature of algae?By converting light energy to chemical energy through the process of photosynthesis, carbon dioxide and water are transformed into organic molecules.
Nearly all algae engage in the process, and in fact, much of what is currently known about photosynthesis was first uncovered through research on the green alga Chlorella.
Like other plants, algae benefit from sunlight, therefore denying them of it will limit or even completely stop their growth. For several days, completely shading the tank or aquarium from light is essential.
Therefore, algae require sunshine because algae can photosynthesize, or use sunlight to change carbon dioxide into biological material.

When rock in the interior of the planet is heated to high enough temperatures, what occurs? Select the best answer from the choices below.
a it gets hotter and sinks into a trench
b the rock melts to create magma
c it forms new mountains underwater
d it causes glaciers to melt
Answer:
B !
Explanation:
I'm basing this off of a lesson I took two years ago, but the answer is B! The interior of Earth is rumored to be filled with magma as a way to have convection currents in itself, and to move the tectonic plates/ create the tectonic plates, if I remember correctly.
If i'm wrong I can still prove why it's not the other choices.
It's not A becuase when rock gets hotter, it rises, and when it cools, it sinks.
it's not C becuase it said "interior of the planet", which it may be referencing somewhere having to do to below the crust. as well, you need to cool rocks as to make it solid, not heated up rocks. but even then, mountains are made by the plates.
it's not D becuase glaciers are affected by climate change and occurrences the biosphere, not the interior of the planet.

What are some ways that natural selection equips organisms for survival in their environment?
Answer:
Well organisms who have traits that are beneficial to them and would make them live long enough to usually reproduce, it would become an adaptive trait. That organism who has that trait will most likely live the longest and reproducing which will pass down their traits. Other same type of organisms who don’t have that trait will most likely die quicker then those who do and they won’t be able to pass on their genes which will lead to the natrual selection being very few of those types. If your born with a non useful trait, you jsut pass it down, you can’t just have the ones that benefit you unless yoru parents have it. This is why at the ”end” there will be more with useful traits and barley any with non.

The orchids benefit in several ways. They get more sunlight and are more easily visited by the moths which pollinate them.Orchids do not harm the trees they grow in. Their roots stay on the bark of the tree; they do not take water or nutrients from the tree.
How dose natural selection affect population by?
Answer:
individuals that develop beneficial traits have a better chance of survival, and are then able to pass on their genes. Eventually, if enough of those genes are passed on, that gene will become more prominent within the population.
