In the early days of life on Earth, plants were exposed to extremely high doses of ultraviolet radiation, Constant UV exposure
resulted in some land plants developing narrow leaves with thick, waxy cuticles. Over many, many generations, these narrow
leaves evolved into needles.
Relate the development of plant needles to the occurrence of mutations,
A)
Plant needles adaptations for survival that some plants developed due to
high temperatures on Earth
B)
Plant needles are the result of leaf cell mutations that made some leaves
thick and waxy, while other leaves did not change,
Plant needles are the result of neutral mutations to leaf tissue that would
neither help nor harm the plants living in such a harsh environment.
D)
Plant needles were a beneficial mutation that increased survival of certain
plants that reproduced and passed the mutated gene to offspring,

What type of RNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide
chain?

Answers

Answer:

mRNA

Explanation:

There are three types of ribonucleic acid (RNA) viz: messenger RNA, ribosomal RNA (rRNA) and transfer RNA (tRNA). These three RNA types function differently from one another. mRNA is a type of RNA that conveys genetic information that was previously stored in DNA into the ribosome for translation i.e. synthesis of amino sequence.

In other words, mRNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide chain using the amino acid sequence that arise from translating it in the ribosomes.

How does convection cause ocean currents?
A. During the process of convection, energy is transferred to the atmosphere forming winds. These winds power surface currents.
B. During the process of convection, the heating of surface water by the sun results in upwelling.
C. During the process of convection, energy in warm water is lost to its surroundings. The water cools, becomes denser, and sinks.
D. During the process of convection, more minerals and gases dissolve in warm water. This increases the density of the warm water and causes it to sink.

Answers

Answer:

C. During the process of convection, energy in warm water is lost to its surroundings. The water cools, becomes denser, and sinks.

Explanation:

Convection refers to the process of transference of heat from one place to another by the movement of gas/liquid particles. Convection occurs when a gas or liquid substance is heated, thereby it expands (increase its volume) by gaining kinetic energy and moving far apart. Energy in the atmosphere and oceans is transferred mainly by convection. In the atmosphere, convection produces wind belts. Moreover, an ocean current is the result of the continuous movement of seawater caused by different forces acting upon the water (i.e., wind, the Coriolis effect, waves, temperature). In the oceans, convection produces currents because the seawater heats up becoming less dense and moves above cooler seawater, emitting heat during the process and causing the continual circulation of water.
