Why does natural selection only affect populations
Natural selection only influences populations; mutation and allele recombination that occur during meiosis and fertilization cause population variation.
Why do populations but not individuals suffer from natural selection?On populations, natural selection operates. In terms of genetic evolution, individuals do not change. While there may be the mutations among the individuals, natural selection works by the changing the traits of the population as a whole.
Why does evolution only affect populations, not individuals?Singular living things do not evolve. Populations change. Given a specific set of environmental conditions, some members of the population are better equipped to live and reproduce because individuals in a population vary.

in redi's second experiment, the independent variable is presence of the gauze, or lack of it, while the dependent variable is appearance of maggots .
What are independent variable and independent variable?independent variable can be described as the variable that stands alone and whereby the other variables can not impact it when one is trying to measure. For instance someone's age is independent variable.
On the other hand ,dependent variable are variable that can not stand alone , hence in redi's second experiment, the independent variable is presence of the gauze, or lack of it, while the dependent variable is appearance of maggots .

anyone know the correct choice to the question?
Answer:
person 1 in row 3's genotype AA or Aa
Explanation:
the trait is recessive (given) which means in order to have it, you must obtain both alleles. in the pedigree, shaded shapes indicate people who have the trait, but person 1 in row 3 is not shaded so their genotype must be AA (dominant) or Aa (dominant leading) and their phenotype would not express the trait, because the dominant allele will "take over"

Answer:
Blood sugar regulation is an example of negative feedback, where the body works to increase the stimulus to maintain homeostasis.
Explanation:
Negative feedback loops are when someone goes out of homeostasis and the body must work harder to restore the lost balance to maintain homeostasis. Blood sugar needs to be regulated so the pancreas must release glucagon or insulin to maintain the proper levels.

A hydrocarbon (molecule consisting of C and H) is hydrophobic (nonpolar)
A hydrocarbon (molecule consisting of C and H) is hydrophobic (nonpolar) and is referred to as a true statement.
What is a Hydrocarbon?This is referred to as an organic compound which consists of elements such as hydrogen and carbon. They are found in crude oil, natural gas, and coal and are highly combustible which is why they are used as sources of fuel.
All hydrocarbons are hydrophobic because the majority of their bonds are relatively nonpolar C to H links and they are involved in a large amount of energy being released when reacted upon thereby making true the correct choice.

Please answer quick will give you brainliest
Answer:c
Explanation:
Bc
A biome is a major community of plants and animals living in a specific geographic area and adapted to specific climate conditions. There are five major types of biomes: grassland, forest, desert, aquatic and tundra.
These major biomes can be divided into different categories (e.g., temperate grasslands).The grassland is a biome that has grasses as the dominant vegetation.The temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).In these regions (temperate grasslands) rainfall is insufficient to support trees.The temperate grasslands have four well-defined seasons. i.e., spring, summer, fall (autumn), and winter.Some examples of temperate grasslands include Argentine pampas, Euro Asian steppes and North American prairies.In conclusion, the temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).

Relationships among organisms
Ecological relationships are the interactions that occur between living beings, which can occur between individuals of the same species (intraspecific relationships) or individuals of different species (interspecific relationships). They can also be harmonic or disharmonious.
What are the types of relationships between living beings?Ecological relationships are the interactions that occur between living things. These relationships can occur between individuals of the same species or of different species and can be classified as harmonic or disharmonious, depending on the consequences they bring to those involved.
With this information, we can conclude that These ecological relationships are very important, as they guarantee the survival of different living beings and help to combat population density, in a way that favors ecological balance. Of course, it does this essentially where there is no human interference.

Explain how stem cells differ from other kinds of cells. Give an example using plantsor animals.
Stem cells are a special kind of cells due to their ability to duplicate and differentiate in different kinds of cells.
there are different kinds of stem cells. The main diference betwen them is the kind of cells they can differentiate into.
for example, when an embrioyo is develoment, the firs cell that is form after the coito is a totipotent stem cell, because it has the ability to diferenciate in every kind of cell in the body. Afer a few weeks, in bovines it would be aroun 8 days, the cells become pluripotent, because they can generate every cell in the body, but the placent. and when we become adults this cells are know as mesechymal (multipotent), that are cells that can diferenciate in certain kind of tissue

Oxygen unloading occurs at the ___________. this process will ultimately ___________ the oxygen partial pressure of the blood leaving this region.
Oxygen unloading always take place at the tissues. This type of process will always decrease the oxygen which is at partial pressure of blood and which is leaving this region.
The Oxygen in the lungs branch into smaller bronchi and bronchioles, which are even smaller tubes. The actual exchange of oxygen and carbon dioxide occurs in the small air sacs at the end of bronchioles, known as alveoli. Alveolar air has a partial pressure of around 104 mm Hg of oxygen, whereas pulmonary veins have a partial pressure of about 100 mm Hg of oxygenated blood.
A decrease in pH (increase in acidity) causes an increase in O2 unloading. Increasing peripheral tissue metabolism, including changes in pH, CO2, and temperature, causes the Oxygen-Hemoglobin dissociation curve to move to the right. This decreases hemoglobin's affinity for oxygen and enhances oxygen unloading.

The t test for independent means is used when each group is tested only once.
'What is t-test?'
A t-test examines two data sets' average values to ascertain whether or not they represent the same population.
To evaluate whether there is a significant difference between the means of two groups and their relationships, a t-test is an inferential statistic that is used. When data sets contain unknown variances and a normal distribution, such as the data set obtained from tossing a coin 100 times, t-tests are utilized.
In order to evaluate statistical significance, the t-test, a test used for hypothesis testing in statistics, uses the t-statistic, the values of the t-distribution, and the degrees of freedom.

as insulin is released, it is wrapped in a sac as it moves across a cell membrane to enter the bloodstream, circulating until it finds its target cell. what is this process called?
The process in which insulin is released, wrapped in a sac and moved across a cell membrane to enter the bloodstream and circulate until it finds its target cell is called exocytosis.
Exocytosis is the process by which a cell releases materials to the exterior by fusing a vesicle containing the materials with the cell membrane and forcing its contents out of the cell. It is an active transport process in which the materials to be transported are packaged in vesicles and secreted out of the cell by fusion with the plasma membrane. In this case, insulin is secreted from the pancreatic beta cells into the bloodstream by exocytosis.
