Answer:

. 2C- acetyl Co-A from the link reaction  enters the kreb Cycle to combine with 4 Carbon Oxaloacetate to form 6-  Citrate

The Citrate forms intermediate Isocitrate, which eventually formed  6-C alpha ketoglutarate.

The alpha-ketoglutarate forms the intermediate succinyl-Co A, which later formed  5C-succinate.

5C -Succinate  forms 4C-fumarate, the latter formed 4C-malate- which eventually formed 4C-oxaloacetate.

The 4C of these compounds is fixed, to ensure constant availability of 4C of oxaloacatate for 2C Acetyl -CoA to bind it for the cycle to continuously occur for production of first product Citric Acid  from which other products are  formed from.

Why a single ovum is produced by oogenesis
Tasya [4]

Answer: The other ova become polar bodies.

Explanation: After meiosis I and II in oogenesis, there should be 4 eggs, but there aren't because the other eggs 3 eggs become these small cells called polar bodies that end up dying out through apoptosis. The reason why polar bodies are made is because they take out extra DNA that the single ovum is supposed to have.

So only 1 egg is made and the rest are polar bodies that get rid of extra DNA and then die by apoptosis.

The evolution of populations due to chance is
Nataly [62]

Answer:

D). genetic drift

Explanation:

Genetic drift is the change in an allele frequency over a period of time. This event has to be random and a chance event.

For example: In a population of a flowering plant there are two types of flowers, blue and yellow. Due to a fire many yellow flowers are destroyed by chance. Now the resultant population will have more blue flowers and when they reproduce the population will eventually evolve to have more blue flowers. Effect of genetic variation is more pronounced in a small population since its easy to disturb the allele frequency.

In pea plants , yellow pod color is recessive and green pod color is dominant . A heterozygous dominant for that trait . What pe
almond37 [142]

The question is incomplete. The complete question is:

In pea plants, yellow pod color is recessive and green pod color is dominant. A heterozygous plant produced offspring with a plant that is homozygous dominant for the trait. What is a percent chance that the pea plant will have green pods.

Answer:

100%

Explanation:

Let's assume that the allele "G" gives green pod color while the allele "g" imparts yellow color to the pods. The genotype of the heterozygous plant would be "Gg". A cross between heterozygous green plant (Gg) with homozygous dominant (GG) plant would produce progeny in following ratio=

Gg x GG= 1/2 GG (green): 1/2 Gg (green)

Therefore, there are 100% chances that the progeny plant will have green pods.
