Answer: Option A.

Polar ice cap in Antarctica.

Explanation:

Scientist drill ice cores from inside the polar ice cap in Antarctica to study variability of climate and differentiate that variability From global climate change. Each layer of the ice tells about weather and what the Earth was like when the first snow fell.

For example, Le grande says that as snow deposits into a growing glacier, the temperature of the air imprints on water molecules.

Icy layers hold particles,aerosols, sea salts, trace elements that were in the atmosphere before and they abide for thousands of years and provide evidence of past events.

DNA carries the instructions to make ?

oksian1 [2.3K]

Proteins.

Protein synthesis (process includes transcription and translation):

The DNA sequence is copied (transcribed) by mRNA in the nucleus then translated in ribosomes which will instruct tRNA to collect specific amino acids to bring back to the ribosome by reading 3 letters at once (called codon, and one codon codes for 1 amino acid). Those amino acids will attach to each other and when the sequence codes for stop, it stops, and a protein forms.

In an area with plants that have thick, small leaves or no true leaves at all, which of the following other conditions are most

Stells [14]

The correct option is B.
The area described in the question given above is desert. Most plants in the desert either have small leaves or no leave at all, in order to regulate the amount of water that is lost to the atmosphere via evaporation of water from the leaves. Most deserts are found within the latitude 30 degree north and latitude 30 degree south. Some deserts can also be found around mountain. The temperate range in desert is quite wide. During the day, the temperature may be as high as 50 degree Celsius and the temperature may drop below zero degree Celsius in the night. Thus, it is always very cold at night compares to during the day.

2. The higher the temerature of the air in the oven, the (speed of which) a cake will bake.

3. Lemon trees receiving the most water produced the most lemons (amount)

4. An investigation found that more bushels of potatoes were produced when the soil was fertalized (amount) more.

5. The amount of pollution produces by cars was measured for cars using gasoline containing different amounts of lead.

Explanation:

The independent variable is what you change and the dependent variable is what is being measured. It is like cause and effect.

Ovules produced by an entirely green plant contain a rare mutation in a nuclear gene that is involved in chlorophyll synthesis,

sveticcg [70]

Answer:

The plant will produce less chlorophyll

Explanation:

The plant still has a functional allele provided by the paternal gamete, thereby the leaves have this enzyme required for chlorophyll biosynthesis. In consequence, the plant can produce chlorophyll pigment but in less quantity, since it has only a functional allele coding for a key enzyme involved in the chlorophyll pathway
