The true breeding individual for all traits is RRYY.

What is True breeding ?

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.

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

Answers

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.

Although animal nervous systems differ in complexity, their nerve cells are still remarkably similar. true false

Answers

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.
