fertilization comes first
it is followed by cleavage which is the rapid cellular division which forms the blastula
then comes gastrulation where the 3 germ layers are formed.
followed by organogenesis which consists first forms the organs and then comes the specialization
Therefore your answer would be B

Part a - identifying the processes of replication, gene expression, and recombination this activity requires that you correctly

Naddika [18.5K]

I found the exercise on the internet with the images and brief descriptions. Attached is an image of it.

To the DNA replication bin:
-Image of one cell dividing into two cells, and the mother cell has its DNA being unfolded and replicated.
-"DNA -> 2DNA (copying one DNA molecule to make two identical DNA molecules)"

To the gene expression bin:
-Image of only one cell with some arrows within it indicating the gene expression flow: DNA -> mRNA -> protein
-"DNA->mRNA->protein"
-"transcription"
-"translation"

To the recombination bin:
-Image with two cells being one the donor and the other one the recipient. The recipient has DNA with different colours pretending to represent that its DNA has different origins.
-"transformation"
-"conjugation"
-"transduction"

Blood does not enter or leave the ventricles during the period called

babymother [125]

That would be D. Isovolumic contraction

As the name states during ISOvolumic contraction the volume of the ventricles doesn’t change and stays the same so no blood enters or leaves the ventricles. The thing that changes is the pressure of the ventricles that increases.

I can explain the process more if u want in the comments:)

Agricultural lands frequently require nutrient augmentation because

fenix001 [56]

The given is incomplete as the options are missing. The correct options for the given question are as follows-

(A) cultivation of agricultural land inhibits the decomposition of organic matter

(B) nitrogen-fixing bacteria are not as plentiful in agricultural soils because of the use of pesticides

(C) land that is available for agriculture tends to be nutrient-poor

(D) the nutrients that become the biomass of plants are not cycled back to the soil on lands where they are harvested

Answer:

Option (D)

Explanation:

In order to carry out agricultural practices, the soil must be rich in essential nutrients for the growth of crops. The soil fertility is a key role in the production of crops.

This agricultural land often requires a large amount of these nutrients and minerals because some of the nutrient minerals are converted into plant biomass which is then used up to produce energy in other sectors. So, the nutrients that were present in the soil are taken away and not transferred back into the soil. This means that the nutrient cycle gets affected. Due to this reason, there requires a constant supply of nutrients into the agricultural fields.

Thus, the correct answer is option (D).
