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.

Fatty acids are simple units of lipids

Explanation:

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:

On some kinds of plants, the meristem is arranged so that when the tip of a branch or stem - which contains the apical meristem, from which new growth is initiated - is cut off, new stems or branches are signaled to start growing from the side, an area called the cambium or lateral meristem. These kinds of plants don’t die if the tip is cut off - instead they grow new branches.

Explanation:

good luck

Answer:

The apical bud produces a hormone, auxin, (IAA) that inhibits growth of the lateral buds further down the stem towards the axillary bud... When the apical is removed bud I'd removed, the lowered IAA concentration allow the lateral buds to grow and produce new shoots, which compete to become the lead growth

7 m/s

Explanation:

Acceleration,

Where v and u are the final and initial velocities of the Justine respectively, t is the time taken for Justin to attain final velocity.

Making v the subject then

v=at+u

Taking u as zero then

Substituting 3.5 for t, 2 as a then

v=3.5*2=7 m/s

Answer:

(c) In combustion, energy is released in several steps, whereas in respiration, it is released in a single step.

Explanation:

Combustion releases energy in a single step in the form of light and heat. Whereas in respiration, energy is released in steps and is stored in the form of ATP.

G=C

C=G

T=A

this is the answer key to any mRNA strand.

Hope this helps! :)

The DNA has adenine (A), cytosine (C), guanine (G), and thymine (T) bases whereas RNA is composed of adenine (A), cytosine (C), guanine (G), and Uracil(U).

It is the process by which RNA is formed from a DNA molecule.

A pairs with U, C pairs with G, G pairs with C, and T pairs with A. The first base of each pair belongs to the template strand of the DNA while the other is RNA.

Answer:

50%

Explanation:

Type A blood and type B blood are both dominant over type O blood.

       A    B

O   AO  BO

O   AO  BO

As is demonstrated by the Punnett square, the children's genotypes will either be AO or BO. Since type O blood is recessive, no child will have O blood, as other dominant alleles are present. 50% will have type A blood and 50% will have type B blood.

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.

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.

Answer:

If in a particular lake, thousands of small fishes are added, then the number of the larger fishes will increase. The reason for this is because in general the larger fishes are feeding on the smaller fishes, thus with the introduction of the thousands of small fishes there will be an increase in their food source.

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.
