Answers

Answer 1

Answer: 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.

Draw a diagram of a virus and label the parts

Answers

Answer:

The diagram of the virus is given below.

Explanation:

Virus may be defined as the simple organism that contain DNA or RNA as their genetic material, surface area is covered with protein coat. Body is divided into head, neck collar and tail fibers. Virus requires a host organism for its growth and reproduction. Virus can affect plants, animals, bacteria and microorganisms.

Viruses are very small, typically between 20 and 300 nanometers in diameter and are so small that they can only be seen with an electron microscope.

How do we explain?

Viruses are not considered to be living organisms because they do not have their own metabolism. They need to infect a host cell in order to reproduce. Once a virus infects a host cell, it takes over the cell's machinery and uses it to make more copies of itself.

Viruses can cause a wide variety of diseases, including the common cold, the flu, and AIDS. There is no cure for most viral diseases, but there are treatments that can help to relieve the symptoms.

The greatest biodiversity on earth is found in the __________ biome.

Answers

The greatest biodiversity on earth is found in the TROPICAL RAIN FOREST BIOME.
The tropical rain forest has constant temperature and high rainfall, because of this the biome contain a diversity of ecological niches which ranges from the forest floor to the canopy. High level of reproduction is also possible as a result of high rainfall that is experienced in the biome.

the answer is Tropical Rain Forests

The organic chemicals that help cell membranes to conserve internal fluids are _____. a. hormones
b. phospholipids
c. amino acids
d. proteins

Answers

the most appropriate answer is B ! as it helps in maintaining isolated internal environment !!

The organic chemicals that help cell membranes to conserve internal fluids are the phospholipids. They are composed of fatty acid, glycerol, phosphate group and a polar molecule. The phosphate group and polar head region of the phospholipids is attracted to water while the fatty acid is repelled by water. They are a major component of the cell membrane in which it encloses the organelles of the cell. It also limits what enters and exits the cell because of its two heads.

A plant native to the chaparral would be expected to _______?

Answers

The answer to the question presented above would be 'require frequent rainfall'. A plant native to the chaparral would be expected to require frequent rainfall. This is because it cannot survive in dry lands and without constant water.

Final answer:

A plant native to the chaparral would be expected to be dominated by shrubs

Explanation:

A plant native to the chaparral would be expected to be dominated by shrubs and adapted to periodic fires in the area. The chaparral biome is characterized by its annual rainfall, dry summers, and nutrient-rich ashes left behind after fires. Some plants in the chaparral produce seeds that only germinate after a hot fire, allowing for regrowth.

This adaptation helps plants in the chaparral thrive despite the harsh environmental conditions. Thus, chaparral-native hay, which produces seeds that grow after a hot fire, would be anticipated to be dominated by shrubs and adapted to recurring fires.
