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.

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.

The plant should be treated as a living thing that should be grown in the earth and contains the stem, leaves, and roots.

At the time when the gardener performed the experiments on the tomato plants so here, the factor should be the light amount that each plant received.

The true breeding individual for all traits is RRYY.

A true-breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits to its offspring of many generations. This means that the parents are homozygous for every trait.

Since RRYY is homozygous for all traits, it will be a true breeding organism if crossed over with another RRYY organism. This is because all the off-springs produced from this cross will also be RRYY that is purebred.

The statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.

Evolution may be defined as a gradual and continuous process that runs over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.

Common genetic ancestors may be diverse into the number of other species due to the theory of evolution. Unnecessary or non-functional organs may be eliminated or shortened due to evolution.

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.

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.
