White blood cells defend the body from _____.disease
carbon monoxide
fungi
infection
blood clots

Answers

Answer 1
Answer:

White blood cells are a type of immune cell that helps the body fight infection. They do this by engulfing and destroying bacteria, viruses, and other harmful microbes. Hence option D is correct.

They also produce antibodies, which are proteins that help the body recognize and fight specific invaders. Carbon monoxide, fungi, and blood clots are not directly attacked by white blood cells. However, they can all lead to infection, and white blood cells can play a role in fighting these infections.

For example, white blood cells can help to remove carbon monoxide from the body and prevent it from causing damage to tissues. They can also help to fight fungal infections by producing antibodies that target the fungi. And, white blood cells can help to break up blood clots that can lead to infection.

So, while white blood cells do not directly defend the body from carbon monoxide, fungi, or blood clots, they can play a role in preventing these conditions from leading to infection.

Therefore, option D, infection is correct.

C

D
North America and South America are connected by land.

Answers

Continental drift is a hypothetical argument that affirms that the continents of the Earth shifted over the geological timeline. It says that the landmasses drifted over the oceans hence creating several continents and oceans.

The correct answer is:

Option C. Similar fossils are found on the coasts of South America and Africa.

The explanation for the correct answer is:

  • The continents either drifted away or clashed together to form present-day continents.

  • Remains from similar species infer that South America and Africa used to be together.

  • The theory of Pangaea states that all the continents were united once but due to a shift in tectonic plates the continents drifted apart.

Therefore, alike fossils found in various continents supports the theory of continental drift.

D. A massive earthquake strikes North America.

Answers

The correct options are as follows:
1. D.
A clade refers to a group of organisms that are made up of evolutionary descendants that originated from a common ancestor. A clade that will survive a series of catastrophic events must be one that is made up of distantly related and diverse species. This is because, those species will have different type of adaptability capacity and will be able to adapt in different ways to the catastrophic events. Due to the differences in their ability to adapt, some of the specie will survive the catastrophic events even if others are wipe out.

2. B.
The mass extinction of one specie usually creates space for another new specie to survive. The new specie that survive the old one may possess the ability to adapt to the event that wipe out the former set of living organisms and thus, the new specie will be able to occupy and reproduce in their new space. Mass extinction is said to occur when the whole population of living organism living in an ecosystem are wipe out as a result of unfavorable conditions.

3. B.
Convergent evolution refers to the independent evolution of similar features in species that arise from different lineages. The species involved usually evolve these traits as a result of having to adapt to similar environments. Convergent evolution usually result in evolution of analogous structures, that is, structures that have similar forms or functions but which are not present in the last common ancestors of the species.

4. C.
 In evolution, gradualism refers to theory that states that evolution occurs slowly and gradually, thus, large changes in evolution are actually product of small changes that occur over a long period of time. The theory of gradualism was originally proposed by James Hutton in 1795.

 5. C.
Mass extinction refers to the wiping out of a a large number of species within a very short time. Mass extinction can occur as a result of severe unfavorable conditions that all the species in an ecosystem can not adapt to. An instance of this is a drastic decrease in global temperature after several massive volcanic eruptions.

Explanation:

A taiga biome is DIFFERENT from a tundra biome because it has A) many coniferous trees.
B) cold winters and cool summers.
C) located in the northern hemisphere.
D) a layer of frozen soil called permafrost.

Answers

Answer:

The correct answer would be A) many coniferous trees.

Taiga and tundra represent the two coldest biomes of the land on the planet.

The average annual temperature of taiga lies between 41° Fahrenheit and 23° Fahrenheit whereas the temperature of the tundra lies below 23° Fahrenheit throughout the year.

It makes the major difference between the plant life of the two biomes. The taiga is characterized by the presence of coniferous forests which consist of spruces, pines, and larches.

In contrast, vegetation in the tundra is mainly composed of grasses, shrubs, mosses, sedges, and lichens.
the answer is A. The tundra is a frozen waste, having very little to no vegetation. While the taiga has conifers growing there
