Which structure is labeled X in the diagram below?

Biology
1 answer:
Vladimir [108]3 years ago
4 0

Answer:

Option D

Explanation:

Diagram is attached.

Capsid protein is a form of structural protein which usually forms part of a complex which later produces protective shell around the nucleic acid in a virus. It is also referred to as coat protein or head protein.  

Capsid acts as a distinguishing feature for identifying an integrated viral genome, plasmids and other genetic material of viruses. In fact, viruses are termed as organisms that encode capsid proteins.  

Hence, option D is correct

Viefleur [7K]

Answer:

The elephant and the sheep exhibit higher sequence similarity because they are more closely phylogenetically related

Explanation:

The elephant and the sheep are mammals, while the crocodile is a reptile, being the mammals the most inclusive group among these three species and it appeared later in evolution. Mammals are organisms that have shared evolutionary features such as warm blood, they produce milk and have hair

Which zone is most likely to have insects and very little plant life?
julsineya [31]

Answer:

The right answer is D. The benthic zone

Explanation:

The limnetic and the littoral zone  all get a lot of sunlight so there are a lot of plant life. The pelagic zone hosts a variety of plant species so this cannot be the correct answer. That leaves us with the benthic zone.

Benthic meaning inhabiting bottom areas or substrates. Plant life at the bottom is very scarce but there are a lot of insect species.

Groundwater___?<br> Is recharged by precipitation
Blababa [14]

Answer: Ground water recharge includes recharge as a natural part of the hydrologic cycle and human-induced recharge, either directly through spreading basins or injection wells, or as a consequence of human activities such as irrigation and waste disposal. Artificial recharge with excess surface water or reclaimed wastewater is increasing in many areas, thus becoming a more important component of the hydrologic cycle.

When you open the door to your house on a cold day, you feel a cold draft. What causes
wariber [46]

Answer:

4. Warm air from the inside moving toward the cold air outside.

Explanation:

A cold draft can be defined as the process in which a current of cold air is being drawn in from the outside. Also, it involves the process in which a current of warm inside air exits or leaves a building through an opening.

This ultimately implies that, when you open the door to your house on a cold day, you would feel a cold draft as a result of the movement between the warm air from the inside moving toward the cold air outside. The warm air that were trapped inside your house would escape through the door due to a difference between the outside (cold) and inside (warm) atmospheric pressure.

Hence, a difference in temperature and atmospheric pressure between the outside and inside air usually causes a cold draft.

<em>Additionally, air typically moves or travels from a region of high pressure to a region of lower pressure. </em>

Hom-ozygous tall pea plants look the same as heterozygous tall pea plants. Formulate a pollination experiment to identify whethe
andre [41]

We can use a punnet square to predict the outcomes of the offspring when crossing two tall plants, and base the experiment we will perform on those probabilities.

A punnet square is a tool used by many genetic scientists. It uses the genetic makeup of the parents to guess those of the offspring.  The punnet square will give us probabilities for each outcome. We can design an experiment in which we make predictions using a punnet square based on Hom-ozygous alleles and heterozygous alleles.

Only by using two Hom-ozygous plants can we guarantee 100% tall plants, and only by using two heterozygous plants can we produce a short plant. Therefore, we can repeat the experiments until a short plant appears or we can only tall plants, and this way we can single out the Hom-ozygous and heterozygous plants.
