What type of RNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide
chain?
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.
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.
Answer:
c
Explanation:
pairing of density dependent and density independent
Answer:
Density-dependent regulation can be affected by factors that affect birth and death rates such as competition and predation. Density-independent regulation can be affected by factors that affect birth and death rates such as abiotic factors and environmental factors, i.e. severe weather and conditions
Which of the following describes an adaptation that relates to reproduction?
A. Hawks have sharp beak to help them quickly catch their prey
B. Elks attach leaves and grasses to their antlers to help them appear larger
C. Polar bears have white fur to help them blend into their surrounding
environment
D. Whales have a thick layer of fat called blubber to help keep them warm
Answer:
Explanation:
A is the correct answer
As Elks attach leaves and grasses to their antlers to help them appear larger, it shows adaptation relating to reproduction, i.e., option B.
What is an Elk?The elk or wapiti is a species of deer included in the Cervidae family which is one of the largest terrestrial mammals in North America, Central, and East Asia.
Female Elks are generally attracted to the larger male Elk which aids in reproduction.
Thus, the correct option is B.

explain why you would recommend the nguni cattle meat to consumers in your locality?
Answer:
Due to their natural growth.
Explanation:
I would recommend the meat of Nguni cattle to consumers in the locality because of their pure quality. These cattles have excellent resistance to internal and external parasites with natural immunity to kill borne diseases. There is no injections or vaccines are given to these cattles which enables them to grow in natural environment. So due to their natural growth, the meat have higher quality as compared to other cattle's meat.

Explain the advantage of an increase in the number of mitochondria in slow twitch fibres. Include at least 2 points in your response
Answer:
To produce more ATP molecules.
Explanation:
The advantage of an increase in the number of mitochondria in slow twitch fibers is to provide more ATP is provided to the muscles. These large number of mitochondria is responsible for the production of large amount of ATP which is a fuel that is used by the muscles of the boy in order to continue working.
