<u>Answer</u>:

1. C. Process one describes cloning and process two describe artificial selection

Through cloning a genetically identical individual is obtained from a single individual. Through artificial selection a hybrid between two individuals with desirable traits is obtained.

2. C. Polygenic

A trait that has a continuous variation has a polygenic inheritance pattern as it is controlled by multiple genes.

3. C. The BW mice would have black and white patches

Codominant genes will produce an individual with an intermediate phenotype as both alleles are simultaneously expressed in the heterozygote.

4. D. Polygenic

Polygenic inheritance occurs when two or more genes determine a trait that has a continuous variation. Each gene has a small effect, but all together have a cumulative effect. Examples of such patterns are height, sking color, eye color, weight etc.

Some helpful tips:

The nucleus is always going to be the big, spherical shape.

The ER is always going to be a weird, folded looking structure attached to the nucleus (rough = has ribosomes on it which are usually represented by little dots, smooth = has no ribosomes on it aka no dots)

The GA looks like the ER but it is not going to be attached to the nucleus like the ER is.

The mitochondria is always going to be pill-shaped and have weird folds inside of it.

Why the horses developed an oxygen debt when they exercised.
user100 [1]

Answer:

The horses developed an oxygen debt when they exercise because they suffered from Exercise-Induced Pulmonary Hemorrhage (EIPH).

Explanation:

A temporary shortage of oxygen in the body tissues during physical exertion such as exercise or a sudden burst of activity is referred to as oxygen shortage.

Horses (compared to humans) are uniquely designed to experience little or none of this.

When the body takes up oxygen, it reacts with glucose to produce energy. This is called Aerobic respiration.

There is also another procedure that the body uses to produce energy. This occurs when glucose is broken down in the cells. After this happens, lactic acid is created but cannot be stored in the body and must be expelled.

This interval when energy is produced without the presence of oxygen is called "oxygen debt".

When a horse is fit, its breathing quickly returns to normal. The longer the time taken for the breathing to return to normal, the less fit the horse is.

One of the factors that can reduce the fitness of a horse is the Exercise-Induced Pulmonary Hemorrhage (EIPH).

This occurs when blood vessle in the lung ruptures causing blood to bleed into the airways. So blood occupies space where oxygen should have. This reduced the amount of oxygen delivered to the blood stream. Hence the oxygen debt takes longer to be repaid.

Cheers

An enveloped virus is dependent on the envelope for its ability to infect a host cell. Which virus most likely uses this mechani
Roman55 [17]

The correct answer is option A- HIV virus.

HIV virus is an example of enveloped virus, that has the ability to infect a host cell by attaching itself to it and fusing with the host cell. Once infected, the virus leaves the host cell and moves to another cells to infect them. The HIV virus contains glycoprotein spikes to attach to the host cell.

Smart home technology is the general term given to basic home amenities that have been fitted with communication technology, enabling some degree of either automation or remote control. It includes things like Home security systems. Environmental controls, like air conditioning, heating, and lighting.
Explanation:
Environmental controls, like air conditioning, heating, and lighting.A spectrometer is a device for measuring wavelengths of light over a wide range of the electromagnetic spectrum. It is widely used for spectroscopic analysis of sample materials. The incident light from the light source can be transmitted, absorbed or reflected through the sample The solution for space exploration is through using mass spectrometers which are used to identify miniature particles present in space. Mass spectrometers are also used in radioactive and carbon dating. When used with gas chronographs, mass spectrometers detect traces of toxic particles and contaminants in air.
