Which of the following cells would not have a well–defined nucleus but would have a thick cell wall and Ribosomes?

DNA replication occurs prior to meiosis and _________. mitosis cytokinesis transcription 2. Adenine with Thymine and Cytosine wi

Thepotemich [5.8K]

Answer:

1. Mitosis

2. Bases

3. Hydrogen

Explanation:

1. DNA replication occurs prior to meiosis and mitosis.

mitosis - cytokinesis - transcription

In cell division, DNA synthesis and replication is carried out during the S phase, in the interphase, a stage that occurs before mitosis and meiosis.

2. Adenine with Thymine and Cytosine with Guanine are known as the nitrogen bases in DNA.

bonds - bases - amino acids

Nucleic acids (DNA and RNA) are composed of nucleotides that contain nitrogenous bases:

DNA: adenine (A), guanine (G), thymine (T), and cytosine (C).

RNA: adenine (A), uracil (U), guanine (G), and cytosine (C).

3. Hydrogen bonds form and hold the DNA together.

hydrogen - peptide - polar

The complementary nitrogen bases are held together by hydrogen bonds:

A=T (adenine pairs with thymine)

C=G (cytosine pairs with guanine)

1. Parasites

2. herbivores

3. phagocytosis

4. Plant

5. oxygen (O2)

6. gills

7. open

8. urea

9. Single-loop circulatory systems have one direction of blood flow. Typically in fish, oxygen is absorbed in the gills, flows in blood to the body organs, and back to the heart, which pumps it directly back to the gills. In double-loop circulatory systems, the heart has multiples of each chamber. Part of the heart pumps blood to the lungs, to get oxygen. This blood flows back to a different chamber where it then gets pumped to the body. Once its oxygen has been used up, it goes back to the heart to be pumped all over again to the lungs.

10. Freshwater animals have lower water and higher salt concentrations than the environment in their cells. This means water constantly tries to diffuse into the animals, which can bloat them. They have special cell processes that remove extra water.

What property makes phospholipids ideal building blocks for cell membranes?

Alenkasestr [34]

Answer:

The polarity of the phospholipid makes it ideal for a building block of cell membranes.

Explanation:

There is the tails which are hydrophobic (water fearing) and the heads which are hydrophilic (water loving). These properties of phospholipids allow the tails to go towards eachother and heads to face the water which maintains a solid structure allowing certain materials to pass through.

How is a junior penguin able to survive in the ocean? someone now this question

valentina_108 [34]

Answer:

the penguins have a special care process since the hatching of the egg, the newborns receive care from their parents and have warmth from them placing themselves between their paws, the parents take turns caring for them and when the father is not with the chick, he goes in search of food, which he gives regurgitated, then the cris can go to a kindergarten where others of the same age are cared for by a herd of penguins, however his parents go to the sea and feed and continue to bring food to their son, this process it is kept until they change plumage and are ready to get their food on their own.
