The members of these kindoms all have cell walls. Which kingdoms are they?

Answers

Answer 1
Answer:

Answer:

Eubacteria, Archaebacteria, Plants, Fungi

Explanation:

The kingdoms Eubacteria, Archeobacteria, Plants and Fungi present organisms that have cell walls in their cells.

Remember that plant cells form plant tissues and are present in some microorganisms. In turn, animal cells lack cell walls, chloroplasts and vacuoles.

The main functions of the cell wall is to provide support, resistance and protection against external pathogens. Therefore, it collaborates with the absorption, transport and secretion of substances.

In addition, the cell wall acts as a filter for plant cells, as it allows the exchange of substances between other neighboring cells.

It also protects against excessive water entry, thus preventing osmotic lysis, that is, cell rupture. Another important function is that the cell wall shapes the various plant cells.
Answer 2
Answer:

Answer: Archaebacteria, Eubacteria, Protista, Fungi, Plantae and Animalia.

Suppose a variation makes an individual member of a species better adapted to its environment, how might that variation affect the individuals reproduction?

Answers

This is basically natural selection/evolution. So when the organism has a certain variation that COULD BE HELPFUL FOR SURVIVAL, its organism will also have that variation. But only if it essential for survival. I hope this helps

SUBMI

Answers

Answer:

A

Explanation:

You can see in the image I attached that it does resemble the shape of a twisted ladder.

Final answer:

The shape of a DNA molecule resembles a twisted ladder, a shape specifically termed a double helix. The two sides of the 'backbone' of the DNA are made of alternating sugar and phosphate molecules, while the 'rungs' are formed by pairs of nitrogen bases.

Explanation:

The shape of a DNA molecule is best described as 'like a twisted ladder'. This specific shape is called a double helix. The two sides of the ladder are made of alternating sugar and phosphate molecules, which form the 'backbone' of the DNA. The rungs of the DNA ladder are formed by pairs of four types of nitrogen bases. These bases pair in a specific way: Adenine (A) with Thymine (T), and Cytosine (C) with Guanine (G). The 'twisting' of the ladder is a key feature of the double helix structure, and this allows the large molecule to fit inside the tiny nucleus of a cell.

Water efficiently absorbs and retains heat.

Heat is quickly released from water.

Water maintains a constant temperature.

Answers

Answer:

the last choice

Explanation:

specific heat is the amount of heat required to raise the temperature this eliminates choice 1 and choice 3 and then the question doesn't specifically mention just water leaving choice 4 which is the answer
