Biology

<h2>Answer:</h2>

<u>D. All of the above </u>

<h2>Explanation:</h2>

Precambrian time incorporates Earth's history from birth up to 590 million years back. That is, the Precambrian traverses 90% of Earth's presence. Fossilized microscopic organisms and blue-green growth demonstrate that crude life existed in any event 3,500 million years prior, and potentially prior.

However, it took another 2,100 million years for eukaryotic cells (plant and creature cells) to show up. These single-celled animals (protozoa) commanded the seas. Multi-cell creatures (spineless creatures) didn't advance until exceptionally late in Precambrian time, around 700 million years prior or 2,800 million years after life initially started on Earth.

The dominant allele is for black fur. The recessive allele is for white fur.
Leokris [45]

Answer:

FF , Black fur.

ff, white fur.

Explanation:

Genotype may be defined as the genetic constitution of the organism whereas phenotype depends on the genotype for the physical expression of the trait.

Let the genotype of the dominant fur (black ) be D and the genotype of white fur (recessive)  is f. homozygous means the individual should have the same allele for the trait. A mouse with homozygous dominant has genotype FF . This mouse has black fur. A mouse homozygous for the recessive trait has the genotype f. This mouse has white fur.

Thus, the answer is FF , Black fur.

ff, white fur.

AFTER DNA replication is complete, a cell is immediately in phase ____ of the cell cycle
bulgar [2K]

Answer: B) G2

Explanation: G1) first gap phase; the cell grows larger and organelles are copied

S) synthesis phase; the cell synthesizes a complete copy of the DNA in its nucleus

G2) second gap phase; the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis

M) mitosis phase; the cell divides its previously-copied DNA and cytoplasm to make two new, identical daughter cells.

So DNA replicates in S phase but then it moves to G2
