Stolb23 [73]

Answer:

The human cell cycle has two main phases: the interphase and the M phase

Explanation:

Just like every cell, the human cell cycle has two main phases which are;

  • The interphase
  • The M phase

The interphase phase is further divided into 4 respective sub-phases namely;

  • G_0 phase which is essentially a resting/quiescence phase. It  reserved for cells that have no need to divide unless they are called upon.
  • G_1 phase, a phase where cell growth and development takes place.
  • S phase, a phase where DNA is synthesized.
  • G_2 phase, a phase where protein is synthesized.

The M phase is known as the active division phase. M can be mitosis or meiosis depending on the type of cells. Reproductive/sex cells will undergo meiosis while somatic/vegetative cells will undergo mitosis.

Mitosis is further divided into prophase, metaphase, anaphase and telophase while meiosis is divided into prophase I, metaphase I, anaphase I, telophase I and prophase II, metaphase II, anaphase II, telophase II respectively.

Why are plants important to the carbon water and nitrogen cycles?
dezoksy [38]

Answer:

The carbon and water cycle I know, but I can't help with the nitrogen cycle. Sorry.

Explanation:

Carbon cycle - The role that plants play in the carbon cycle is that they take in our carbon dioxide and put out oxygen, which we breathe. So we give the plant air and they give us air.

Water cycle - The role that plants play in the water cycle is when it rains, the plants absorb some of the water in their roots, thus making them strong and therefore helping the ground not become a mud hole.

Sorry that I can't help with the nitrogen cycle. But I hope what I was able to help you with helps!

1. Why is the nitrogen cycle important?
Temka [501]

Answer:

Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow.

If you made a Punnett square showing Gregor Mendel’s cross between true-breeding tall plants and true-breeding short plants, the
nekit [7.7K]

Answer:

C

Explanation:

Assume that allele A is the dominant allele that produces the dominant phenotype (tall) in plants that have at least one allele A, and allele a is the recessive allele that produces the recessive phenotype (short) in plants that have two alleles a.

In the parental generation, a true-breeding tall plant has the AA genotype (phenotype: tall), and a true-breeding short plant has the aa genotype (phenotype: short).

We have the Gregor Mendel's cross as in the image attached here.

All of the F1 generation (offspring plants) have the Aa heterozygous genotype, and therefore, they are all tall.

The answer is c (the offspring plants have a genotype that was different from that of both parents).

iren [92.7K]

Answer: The correct answer is - 3) olfactory receptors neurons that detect smell. 4) photoreceptors neurons that detect light .

1) and 2) statements are correctly matched in the question..

Olfactory receptors are also called odorant receptors. The olfactory receptor neurons detect smell and thus give a sense of smell to the organism. They are present in the nasal cavity.

Photoreceptor neurons are those that detect light and they are present in the retina of eye.
