Prokaryotic DNA is enclosed within a nucleus, while eukaryotic DNA is not.<br>O True<br>O False​
blagie [28]

Answer:

False

Explanation:

Prokaryotes do not have a nucleus.

This means their DNA is not enclosed in a nucleus and instead is in the cytoplasm.

On the other hand, eukaryotes have nuclei, so their DNA is enclosed within a nucleus.

So, this statement is false.

Which adaptation helps polar bears maintain a constant internal temperature (thermal homeostasis) in cold weather? three layers
lubasha [3.4K]

Answer:

The polar bear is an animal which is prevalent in the arctic region of the world which is characterized by very cold icy climate.

They adapt to these climatic conditions by maintaining a body temperature of 37°C through its thick fur and tough skin. It also has an insulating fat layer (adipose tissues) which is very thick.

This insulation helps in keeping the animal very warm in extreme temperatures.

This is a tissue that makes up most of the fleshy part of a plant. The fleshy part of the plant is shown. Which does this tissue
MaRussiya [10]

Answer:

Dermal and vascular tissue

Explanation:

The dermal system of plants works together with the vascular system to carry out sweating.

The dermal tissue is wound by the epidermis and periderm. The epidermis is varied in its structure and function, among which its main function is that of protection and vegetal covering. These cells are covered by a cuticle, responsible for providing an impermeable characteristic to the cell. In this region, there is the presence of guard cells, which are responsible for the process of closing and opening pores, called stomata. This structure serves to control the plant's internal gases, such as the entry and exit of water vapor, CO2 and oxygen. The periderm, in turn, is the secondary protective tissue in vegetables. It has a loose organization, allowing an aeration of the internal tissues of the roots and stems. It is in this region that we find mainly the suber, the best known being cork, which is a classic example of periderm.

The vascular system is formed by xylem and phloem. Xylem is the main conductive tissue of water, nutrients and minerals. Its composition is formed by dead cells, with lignin impregnation. It is found more internally in relation to phloem, also acting as an important supporting tissue, as it has special cells called tracheids and vessel elements. Both are elongated cells that have points on their wall to communicate with one cell to another. Phloem, in turn, is formed by living cells, being the main responsible for transporting elaborate sap from the leaves to the stem and roots. It is located just below the plant's bark, formed by a special cell called sieving elements, because that cell has sieving areas, through which the protoplasm of the adjacent cells bind. This region is known as the riddled plaque. These sieved tube elements also have the characteristics of being associated with special parenchymal cells called companion cells.
