what is the function of mitosis?​

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Natural selection is the difference in the ability to live and reproduce from an individual that is caused by differences in the suitability of the organism's phenotype with the environment. This is a key mechanism of evolution, changes in characteristics that are passed on from generation to generation. Charles Darwin is the person who popularized the term "natural selection" and compared it to artificial selection, which he thought was intentional, while natural selection was not.

Variation exists in all populations of organisms. This happens due to random mutations that appear in the genomes of individual organisms, so that their offspring can inherit these mutations. Throughout the life of an individual, its genome will interact with its environment causing populations variations in traits. The genomic environment includes cell chemistry, other cells, other individuals, populations, species, and the abiotic environment. This environment will determine which genome changes will be beneficial and which will be detrimental.

Because individuals with a trait variant that is favorable to their environment tend to survive and reproduce more than individuals with another variant that is less favorable, the population for that trait variant grows. Other factors that influence reproductive success include sexual selection (now often included in natural selection) and fecundity selection.

Explanation:

Answer:

A. It's more time and cost effective to do it yourself

The time it takes to reach the sixth generation would be 60 minutes.

It is not possible to calculate the number of cells after the fourth generation without additional information such as the initial number of cells and the growth rate of the organism.

To calculate the time it would take to reach the sixth generation, you would multiply the generation time of the organism (10 minutes) by the number of generations desired (6).

Formula:

Generation time x Number of generations = Total time

10 minutes x 6 generations = 60 minutes

So, it would take 60 minutes to reach the sixth generation.

Since the Earth is pivoting, the daylight radiates on objects from various headings as the day heads on. This makes the sizes and states of shadows change.

The place of the sun overhead would redirect our shadow if we somehow happened to remain in a similar spot all day in light of the fact that the sun moves with the progression of time. The sun ascends in the east so around then our shadow is framed towards the west side and begins diminishing when the sun arrives high overhead.

At the point when the sun comes to the highest point of our head, then, at that point, no shadow is framed and when the sun set happens the length of the shadow again diminishes so we can say that the size of the shadow changes as the sun changes its situation.

C3 plants fix carbon dioxide directly into a three-carbon compound, C4 plants have specialized cells that fix carbon dioxide into a four-carbon compound, and CAM plants fix carbon dioxide into a four-carbon compound at night, which is then converted into glucose during the day.

C3 photosynthesis is the most common type of photosynthesis and is found in most plants. In C3 photosynthesis, carbon dioxide enters the leaf through the stomata and is immediately fixed by the enzyme RuBisCO into a three-carbon compound. This process is called the Calvin-Benson cycle, and it takes place in the chloroplasts. The oxygen produced is released through the stomata.

C4 photosynthesis is an adaptation found in plants that live in hot and dry environments. These plants have specialized cells called bundle sheath cells that surround the vascular bundles in the leaf. These cells have a high concentration of RuBisCO and other enzymes that help to fix carbon dioxide into a four-carbon compound. This four-carbon compound is then transported to the chloroplasts, where it is converted into glucose. This process helps to prevent photorespiration and increases the efficiency of carbon fixation.

Scatterplots represent the relationship between two variables and how correlated they are. Outliers are also identified in these plots. A) Triangles represent how the percentage of individuals expressing symptoms increase as the percentage of positive individuals increases. B) r = 0.85 is a high positive correlation. C) Outliers are atypical values that might cause misinterpretation of results.

A scatterplot is a graphic tool that represents the existing relationship between two variables. It turns out to be an easy and fast way to interpret data.

To make the representation we use a cartesian graph and by looking at the intersection points between dependent and independent variable, we can analyze what type of relationship there is. The pattern of points intersection can show the relationship between the two variables.

- High positive correlation ⇒ points are too close to each other

- Low positive correlation ⇒ points are separated from each other

- High negative correlation ⇒ points are too close to each other

- Low negative correlation ⇒ points are separated from each other

By looking at these intersection patterns, we can also identify the outliers, which are atypical and abnormal values that differ significantly from the whole data set. This value is not consistent with the rest of the observations.

Outliers suggest something went wrong while sampling or something unusual is involved. Usually, these values are eliminated from the experiment to avoid misinterpretations.

In the exposed chart,

A) Triangles represent the relationship between the variables percentage of people in the sample who tested positive and the percentage of people in the sample who experienced symptoms. This is, how the percentage of individuals expressing symptoms increase as the positive individuals increases.

B) r = 0.85 is a high positive correlation. As we can see on the chart, all empty triangles are very close to the straight line and to each other. This is a high correlation.

C) Outliers are atypical values significantly distant from the other values. They suggest a researcher's mistake or something strange in the sampled individual. These values do not represent most of the population, and if including them in the analysis, they might lead to misinterpretations of the results.

The first two statements in the above sentence are untrue, whereas the third one is.

Direct bone or skeleton ossification refers to the process of creating bones. Beginning between the fourth and fifth stages of embryonic stages and continuing until about age 25, but even this varies slightly between person to person. Intramembranous and endochondral bone ossification are the two forms.

Each of these procedures begins with a mesenchymal tissue precursor, but they vary based on how that major contributor transforms into bone. Intramembranous ossification, which converts mesoderm tissue directly into bone, generates the flat components of the brain, neck, and most of the cranial bones. Endochondral ossification, which starts with mesenchymal tissue changing into an early variety of cartilage and is finally replaced by bone, is the process by which the axial skeleton and bone are produced.

Energy is not only stored in biomass. Some of it is used for biological processes. Which process produces offspring is called reproduction.

Energy is the power that is carried out to carry out an activity. Energy cannot be created but can be transferred and changed from one form to another. Plants use energy from sunlight to produce food through the process of photosynthesis which is then stored in the form of biomass. The energy then passes to other living things when plants are eaten by herbivores and so on.

Reproduction is the process of producing offspring that occurs when the egg and sperm fuse together to form a fetus. An energy source is needed in the sperm neck to be able to move actively during the fertilization process so that fertilization can occur.
