one daughter molecule contains both parent strands and one daughter molecule contains both newly synthesized strands each daught
vivado [14]

Answer:

<h2> Each daughter molecule contains one parent strand and one newly synthesized strand</h2>

Explanation:

In DNA replication, each daughter molecule contains one parent strand and one newly synthesized strand because DNA replication is semi-conservative. One template strand is parental strand and the other one is its complementary which is new one, which is synthesized by DNA polymerase enzyme. So both  daughter molecule contains one parent strand and one newly synthesized strand and they are same in the sequence of bases because each strand contains one original parental strand.

Why is pyruvate imported from the cytoplasm into the mitochondrial matrix?
grin007 [14]

Answer:

So that oxidation of pyruvate can take place in mitochondria.

Explanation:

Pyruvates is produced in the glycolysis process which occurs in the cytoplasm. So pyruvate is produced in the cytoplasm of the cell. Pyruvate is produced by partial oxidation of glucose and to be fully oxidized it has to enter in the mitochondria.

So after entering the mitochondria the pyruvate first converts into acetyl CoA than this acetyl CoA enters in the citric acid cycle and fully oxidized into CO2. This oxidation generated NADP and FADH2 which provide reducing power during oxidative phosphorylation.

An ecologist was observing two species of mouse that lived at different elevations on a mountain. In the lab, she observed that
dolphi86 [110]

The species had the same fundamental niche, but the high-altitude species was occupying a perceived niche, as it was inhabiting a different ecosystem, with different adaptations, but being the same species.

<h3>Why is the perceived niche considered a subset of the fundamental niche?</h3>

Well, as we know, the perceived niche is smaller than the fundamental niche, in other words it is a specific portion of the fundamental niche, so it is considered a subset of the fundamental niche.

With this information, we can conclude that the species had the same fundamental niche, but that the high-altitude species was occupying a perceived niche, as it was inhabiting a different ecosystem, with different adaptations, but being the same species.

In Whitetail deer, there is a gene for coat color. Brown coats (B) are
ahrayia [7]

Answer: All of the offspring are brown. The chances of getting a brown deer is 100%.

Explanation: The buck is homozygous dominant, meaning he has two of the brown (B) allele. The doe is white, and since the allele for a white coat is recessive, it has to have two white (b) alleles.

Set up a Punnett square with BB on one side and bb on the other. The results of this are 4 offspring all with the genotype Bb. Because brown (B) is dominant, all of them are brown.

To find the chance of getting a brown deer, take the number of brown deer (4) and divide it by the total number of outcomes (4). This gets you 4/4 or 1. As a percent, that would equal 100%.
