Morphological distinction is one of the steps necessary for speciation to occur.
What are the other two?

Answers

Answer:

Genetic Separation / Geographic isolation

Explanation:

Morphological distinction (or phenotypic differentiation) can be defined as the diversification of a set of observable physical characteristics in a population, capable of differentiating certain species.

The genetic separation occurs when the division of a group of genes into two or more pools of genes separated over time and depending on several other situational factors.

Geographic isolation occurs due to the physical separation of subpopulations of a given species. The barriers that isolate these subpopulations can be, for example, a river that cuts through a plain, a valley that divides plateaus or a portion of the sea that separates islands and continents.

The sperm and the ovum are called haploid (as they have only 23 chromosomes) which is half the number of chromosomes seen in all the other human body cells. What is the significance behind the maintenance of this special chromosomal number in the male and female gametes?

Answers

Answer:

During the process of meiosis(The process of cell division through which the germ cells such as the reproductive cells are formed), the sex cells produced are haploids (have only 23 chromosomes). This is significant as during the process of fertilization, the nucleus of the sperm (containing 23 chromosomes) and the nucleus of an egg (containing 23 chromosomes too) fuse, hence, retaining the original number of chromosomes in the zygote formed. i.e 46 chromosomes.

A dominant allele is often covered up or masked by the recessive allele. True or false?

Answers

Answer:

Explanation:In a heterozygote, the allele which masks the other is referred to as dominant, while the allele that is masked is referred to as recessive.

Answer:

If the alleles are different, the dominant allele will be expressed, while the effect of the other allele, called recessive, is masked. In the case of a recessive genetic disorder, an individual must inherit two copies of the mutated allele in order for the disease to be present

Which of the following BEST explains how scientists are able to determine the
structure of Earth's interior?
1) Scientists gather indirect evidence using seismic waves (Earthquakes) along with what is visible at Earth's surface.
2)Drilling deep within the Earth.
3)By cutting into other terrestrial planets.
4) Our modern knowledge of the Earth's interior is just a guess that many scientists have accepted.

Answers

Answer:

I think number 1 is the answer.

Scientists gather indirect evidence using seismic waves (Earthquakes) along with what is visible at Earth's surface. The correct option is 1.

What are seismic waves?

Seismic waves are caused by sudden movement of materials within the Earth, such as fault slip during an earthquake.

Seismic waves generated by earthquakes or explosions can travel through the Earth's interior, revealing information about the properties of the rocks and other materials they pass through.

In addition to seismic data, scientists use other indirect methods such as magnetic and gravitational field studies, as well as analyses of rocks and minerals found at or near the surface.

Scientists collect indirect evidence by observing seismic waves (Earthquakes) as well as what is visible on the Earth's surface.

Thus, the correct option is 1.

What is a Eukaryotic cell?

A eukaryotic cell is defined as the type of cell that has a true nucleus, and other organelles are well defined and enclosed in a membrane that has a large and complex cell that distinguishes them from prokaryotes.

This is the cell with a true and well-defined nucleus, lysosomes, cell membrane, and a cell wall is a characteristic of a plant cell because they are enclosed in a cell wall, unlike animal cells. Eukaryotic cells are found in animals and plants, while bacteria and archaea have prokaryotic cells.  

Therefore, a eukaryotic plant cell is the correct classification of this cell. So, the correct option is D.

When the water availability of a plant's environment decreases, the plant can respond by closing its stomata. This reduces the amount of water that the plant loses through its leaves due to transpiration. Closing the stomata also reduces the amount of carbon dioxide that the plant can take in through its leaves, which will most likely result in A. a decreased rate of photosynthesis. B. no change in the cellular processes of the plant. C. an increased rate of photosynthesis. D. an increased rate of cellular respiration.

Answers

Answer:

A. a decreased rate of photosynthesis.

Explanation:

Stomata is a structure in the leaves of higher plants, which they use majorly for the purpose of gas exchange. However, the process whereby plant loses water called transpiration also occurs via the stomata. In a situation whereby the availability of water in a plant's environment is low, the plant responds by closing its stomata in order to conserve water (reduce the amount of water that the plant loses through its leaves due to transpiration).

Closing the stomata by plants means not allowing ample carbon dioxide (CO2), which is needed for the process of photosynthesis to occur, to enter the plant. This will most likely result in a DECREASED RATE OF PHOTOSYNTHESIS.

explain how and why an earthquake occurs in thorough detail. You should also be identifying the four labels below within your explanation. A good answer would be longer than a paragraph (but < 3)

Answers

Answer:

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!

In Units 4A and 4B, we have learned about photosynthesis and cellular respiration. Which of the following statements is true?
a. The reactants of photosynthesis are the reactants of cellular respiration.
b. Photosynthesis produces light energy while cellular respiration produces chemical energy.
c. The products of photosynthesis are the reactants of cellular respiration.
d. Photosynthesis and cellular respiration use light energy to convert to chemical energy.

Answers

Answer:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

what is the full form of tree​

Answers

Explanation:

A tree or large tree is called a long-standing woody plant. In botany, the tree is one of the most durable plants that maintains its leaves by growing a stem or trunk. In some definitions, the use of the tree is such that it is the only woody plant. It is the only plant from which wood is obtained. It is not possible to determine the exact height of the trees, but overall the adult trees reach at least 6 meters [citation needed]. In the structure of the tree there are usually branches that are attached to a large trunk. Compared to other plant and animal species, trees have a long life. Some species of trees are more than 100 meters tall, and some live for thousands of years. Trees are important elements of natural landscape, gardening and landscaping. [1]
