In one of the first steps in Prophase I of meiosis,
A) the cell divides into four daughter cells.
B) the chromatids separate and move to opposite ends of
the cell.
C) half of the chromosomes are made inactive.
D) homologous pairs of chromosomes form tetrads

Answers

Answer 1

Answer:

D) homologous pairs of chromosomes form tetrads

Explanation:

During prophase I, the homologous chromosomes condense and become visible as the x shape we know, pair up to form a tetrad, and exchange genetic material by crossing over.

What is the name of a specific type of model that shows how animals diverge during evolution?(1 point)

taxonomy

diagram

cladogram

Answers

Answer:

Cladogram.

Explanation:

A cladogram is a diagram used in cladistics to show relations among organisms. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. In biology, taxonomy is the scientific study of naming, defining and classifying groups of biological organisms based on shared characteristics. Taxonomy would not be based on genetic diversion during evolution, it only describes similar characteristics amongst animals.

I also chose taxonomy on the test and it was wrong. The right answer said cladogram.

A specific type of model that shows how animals diverge during evolution is Cladogram. So, the correct option is D.

What do you mean by Evolution?

Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms.

A cladogram is a diagram that shows the evolutionary relationships of several clades. A clade is a group of organisms, which contains both an ancestral species and its descendants. The common ancestor appears at the root of the cladogram.

Therefore, A specific type of model that shows how animals diverge during evolution is Cladogram.

What does it mean when we say that DNA replication is semiconservative ?

Answers

Answer:

Basically, when people say that DNA replication is semi-conservative they are saying that two identical copies are being made from the original DNA strand.

Explanation:

The two new strands contain one side of the original DNA and another side of  synthesized pair.

According to Chargoff rule, if a sample of DNA is 32% Adenine, what is the percentage of Guanine?​

Answers

Answer:

18%

Explanation:

Chargaff's rule states that A = T and C = G

The equation for this must be A + C = T + G

A and T should both be .32 since they're equal

--> .32 + C = .32 + G

Both sides must equal each other by .50

.50 - .32 = .18

.18 × 100 = 18% Guanine and also 18% Cytosine

If you tossed a coin a total of ten times and got a total of three heads, what is the probability of tossing heads in your next toss?​

Answers

Atleast 3 Heads in 10 Coin Tosses
0.95 is the probability of getting 3 Heads in 10 tosses.
Answer:   1/2

In decimal form this is 0.5 and it converts to 50%

===================================================

Explanation:

Assuming the coin is a fair coin, meaning that each side is equally likely to be landed on, this means the probability of flipping heads is 1/2 = 0.5 = 50%

This is true of any flip. The coin doesn't have memory of previous events, so past events do not affect its probability. Each event is independent of any other.

Answer:

Enzyme A acts as a catalyst by lowering the activation energy the reaction needs in order to take place this would in turn lower the reaction time of the reaction lading to a faster reaction. when conditions around the enzyme change this may lead to the breaking of hydrogen bonds causing the active site to change in shape, this change would would lead to the substrate no longer being able to fit which would lower the rate of reaction.

One could be forgiven for the assumption that the classic 'onion root tip squash' ... magnification using the eyepiece and objective lens, you will need to be able to ... about how the cells were being used, and had been given no explanation, ...

Explanation:

The cells of the ONION ROOT TIP undergo cytokinesis. This process is evidenced under the microscope by the formation of the CELL PLATE between two daughter cells.

Mitosis is a type of somatic cell division that has four main steps (prophase, metaphase, telophase and anaphase) followed by cytokinesis.

Moreover, cytokinesis is the division of the cytoplasm to form two daughter cells.

The cell plate is a transient compartment that grows between daughter cells. Once cytokinesis is completed, the cell plate gives rise to the cell wall.

In conclusion, the cells of the ONION ROOT TIP undergo cytokinesis. This process is evidenced under the microscope by the formation of the CELL PLATE between two daughter cells.
