When two different forms of a virus infect the same cell, the host cell may manufacture viral particles by a process called antigenic shift.

<h3>What is an antigen?</h3>

An antigen is any molecule or molecular structure that may trigger a suitable immune response in the host.

An antigen can be the target for antibody binding during classical adaptive immune responses.

In conclusion, when two different forms of a virus infect the same cell, the host cell may manufacture viral particles by a process called antigenic shift.

You have a 15kb plasmid. EcoRI cuts the plasmid into 7kb and 8kb pieces, and BamHI cuts the plasmid into 1kb and 14kb pieces. If
Harman [31]

Answer:

a. Bands at 1kb, 6kb and 8kb

Explanation:

The EcoRI and BamHI are the restriction enzymes which cut the DNA sequence especially a plasmid at specific sites called the restriction sites.

The restriction enzymes produces bands of specific length therefore these restriction enzymes are used to estimate the approximate length of the DNA.

In the given question, the

1. EcoRI- produces two strands of 7 kb and 8 kb

2. BamHI- produces two strands of 1kb and 14kb

This shows that the length of DNA sequence is 15kb

But when the DNA strand are digested with both the enzymes simultaneously then it will produce three bands as:

i) 14 kb can be broken down in 2 bands of 6 kb and 8 kb

ii) 1 kb band is already produced by the Bam HI.

This shows that 1+6+8= 15 kb

Thus, Option-A is correct.

Organisms use different types of adaptations to aid in their survival. many different types of animals hibernate throughout the
zalisa [80]

Option (A) Torpor is the correct answer

Organisms that undergo hibernation have the ability to slow down their metabolism so as to lower the core temperature. This process is known as Torpor.

<h3>Why is torpor important for organisms undergoing hibernation?</h3>

Torpor is a state in animals where they lower all their metabolic activities and bodily functions so as to keep the body temperature low.

It is done by the animals to conserve resources in conditions where scarcity of food is there.

Some birds undergo torpor to conserve fat in the body.

Some animals use this technique of torpor to survive competition with other species.

These organisms come back to normal physiology when the conditions become favorable.

In a study published in the journal Nature, scientists studied eight ponds in Florida: four that were populated by a species of
AlexFokin [52]

Answer: the rate of pollination of flower, in a field next to a pond with no fish, will DECREASE.

Explanation:

POLLINATION is defined as the process by which flowering plants, through the aid of external agents such as insects,wind, water and other animals, are able to transfer pollen grains from an anther to a receptive stigma. Insects are the most common pollinators. They visit flowers to obtain nectar and pollen as source of food. Flowers use various features, such as colour and scent, to attract and guide insects to the food source within them. In the process of reaching their source of food, insects bring about pollination.

From the study conducted by scientist in Florida, eight(8) ponds where subjected to the the study. The first four (4) ponds had species of fishes that fed on dragonflies and dragonfly larvae, hence the reason for a decrease in the population of the dragon flies in the area around it. While the remaining four (4) ponds had NO fish and the area around it is populated with dragonflies and dragonfly larvae. This is so because of the absence of fish.

It was then noted that the dragon lies fed of the insect pollinators such as the bees and butterflies. Since these dragonflies and its larvae are abundant in the field which is close to the pond with no fish, they will grossly depend on the insect pollinators as their source of food thereby decreasing the rate of pollination in the field next to the pond with no fish.

My name is Ann [436]

The best answer is B (semi permeable)
The cell membrane of a red blood cell is semi permeable membrane. This is a type of biological membrane that will allow certain molecules or ions to pass through while barring others.

Red blood cells have very thin membranes that allow oxygen diffuse through quickly. They are also permeable to water and osmosis across the membrane occurs very rapidly. In the body, they are bathed  in isotonic plasma in which case water movement  into the cell is equal to water movement out of the cell and so the cells remain intact.
