Answers

Answer 1
Answer:

Answer: The given statement is False.

Sunlight is considered as a major source of energy for all life forms that are present in the ecosystem. But it is not a food resource, instead the energy from sunlight (called solar energy) is used in the formation of food through a process called photosynthesis ( that takes place in green plants and algae). The food prepared by plants is used by different organisms in the ecosystem through food chain.

Thus, the given statement is False.

Answer 2
Answer:

Answer:

Which statement best explains why a karyotype can be used as a scientific report

Answers

The correct answer is:

"A karyotype can be used for reporting medical concerns and possible genetic disorders

Explanation;

A Karyotype is the number of the chromosome in a cell. In humans, the typical amount of chromosomes is 46. Seldom humans have a varying number of chromosomes and then the karyotype (for example the number) can be used for inscribing for example of genetic disorders- so the answer is that it can be used for reporting of genetic disorders.



The correct answer for the question that is being presented above is this one: "A karyotype can be used for reporting medical concerns and possible genetic disorders." A Karyotype is the number (or characteristics of) of the chromosome in a cell. In humans the typical number of chromosomes is 46. 

A factor that is necessary for the formation of a new species is

Answers

The factors that are necessary for the formation of new species are genetic mutations, isolation, some environmental factors, etc.

What is referred to as variation?

The difference in DNA among individuals or the differences between populations is referred to as variation.

There are multiple sources of genetic variation including the following:

  • Genetic mutation.
  • Geographical isolation.
  • Reproductive isolation.
  • Environmental factors.
  • Geographical barriers.

Variation can leads to the formation of new species.

Thus, these are some factors that are responsible for the formation of new species.

Which non-specific defense mechanism is mismatched with its associated body structure or body fluid?

Answers

Answer:

Mucociliary escalator- intestine

Explanation:

This is a complete mismatched. Simply because this  defense mechanism maintains the respiratory tract by sweeping  foreign substances inhaled with air molecules upwards in the trachea, to be swallowed or spit out .

It is composed of the Goblet cells and  Ciliated Epithelium.It is a defence mechanism which protects the lungs parenchyma from infection and  inflammation from foreign particles and microorganism. The mucus produced from the Goblet cells trapped theses particles,at the same time moistening the pathways,  while the cilliated epithelium beat in upward fashion to sweep them out through the trachea. To complete mucociliary clearance.

Describe the three layers of tissue found in artery and vein walls.

Answers

As in the arteries, the walls of veins have three layers, or coats: an inner layer, or tunica intima; a middle layer, or tunica media; and an outer layer, or tunica adventitia. Each coat has a number of sublayers. The tunica intima differs from the inner layer of an artery: many veins, particularly in the arms and legs, have valves to prevent backflow of blood, and the elastic membrane lining the artery is absent in the vein, which consists primarily of endothelium and scant connective tissue. The tunica media, which in an artery is composed of muscle and elastic fibres, is thinner in a vein and contains less muscle and elastic tissue, and proportionately more collagen fibres (collagen, a fibrous protein, is the main supporting element in connective tissue). The outer layer (tunica adventitia) consists chiefly of connective tissue and is the thickest layer of the vein. As in arteries, there are tiny vessels called vasa vasorum that supply blood to the walls of the veins and other minute vessels that carry blood away. Veins are more numerous than arteries and have thinner walls owing to lower blood pressure. They tend to parallel the course of arteries.
