Answer:
The answer is "the amount of light each plant receives
At the time of graphing the data, the factor that should be considered as the independent variable should be the light amount that each plant received.
What is the plant?The plant should be treated as a living thing that should be grown in the earth and contains the stem, leaves, and roots.

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.

Water - 4.18
Place the areas in order based on how fast they’ll heat up on a sunny afternoon. Start with the fastest and end with the slowest.
PLEASE ANSWER QUICKLY I WILL GIVE BRAINLIEST!!
Answer:
Correct answer is A-C-B
Explanation:
Just took the test
The concrete has the lowest specific heat, so it requires very little heat to heat up, making it the fastest substance to heat up; the second is grass, and the third is water, which requires a high temperature to heat up, so A-C-B is the correct order.
What is the significance of the specific heat of the substances?Specific heat is explained as the amount of heat that is needed to raise the temperature by 1 degree, and here the water needs the highest temperature to raise the temperature by 1 degree as a result, even if the water gets a little bit more temperature, it will not be too hot right away.
Hence, the concrete has the lowest specific heat, so it requires very little heat to heat up, making it the fastest substance to heat up; the second is grass, and the third is water, which requires a high temperature to heat up, so A-C-B is the correct order.

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.

Although animal nervous systems differ in complexity, their nerve cells are still remarkably similar. true false
Answer:
TRUE
Explanation:
The nervous system only exists in animals. Neurons are the nerve cells that compose the nervous system.
The neuron´s principal function is to catch stimuli from the exterior convert them into nerve impulses that get transported to the control centers. These control centers interpret the signal and send an answer to the stimuli.
The control centers in invertebrates are ganglia, while the vertebrate´s control centers are the spinal medulla and the encephalon.
The signal transport occurs from cell to cell in inferior animals and through nerves in superior animals.
There is a progressive increase in the complexity of the nervous system. It evolved from primitive animals to the most superior ones. This evolution is especially noticeable in the development of the encephalon as the control center.
However, the basic nerve cell is very similar in all animals.

How would the author of "Are 'Green' Cars Really All That Green?" dispute the claim in "Cars Without Gasoline Are Here" that biofuels are a good replacement for fossil fuels?
Answer:
A. By noting that biofuels come from vegetables such as corn and sugar beet.
Explanation:
The author claims that biofuels are a good replacement for fossil fuels in the vehicles because it produced less carbondioxide gas as compared to fossil fuels. The biofuels also produced pollution but less as compared to fossil fuel. This biofuel is extracted in the form of Bioethanol which is a type of alcohol made by fermentation process of starch crops such as corn, sugarcane, or sweet sorghum. This biofuel made from biological materials that decrease the production of carbondioxide gas.
