What is the variety of gene combinations that exist within a population called?

Answers

Population geneticists study the variation that naturally occurs among the genes within a population. The collection of all the genes and the various alternate or allelic forms of those genes within a population is called its gene pool.

A population's genetic diversity can be quantified via genetic variation, genetic diversity is the term used to describe the genetic variation of an entire species.

What is genetic variation?

Each variant of a gene is referred to as an allele, and genetic variations are the variances in DNA segments or genes across individuals.

A population's naturally occurring genetic diversity is studied by population geneticists. A population's gene pool is made up of all the genes and different alternative or allelic versions of those genes.

Some genes exist in a number of forms, all of which share the same genetic locus on a chromosome.

Therefore, genetic diversity is the variety of gene combinations that exist within a population.

Write a brief explanation of what is meant by the phrase the carbon cycle, the waste products of one system are the stuff of life for another."

Answers

Answer:

Explanation:

Carbon cycle is the flow of carbon between the atmosphere and the ecosystem.

From the phrase it can be deduced that carbo which is gotten as carbondioxide is a waste product from respiration. We breathing in oxygen and exhale carbondioxide as waste product.

This carbondioxide is use in photosynthesis.

The carbondioxide react with water in the presence of light energy from sun and chlorophyll to produce carbohydrates or food and oxygen. It is the stuff of life for plants because it is use in plants photosynthesis.

Name the three types of population distribution,
describe each, and explain the conditions that
govern each.

Answers

Answer:

random clumped uniform i think

Explanation:

Answer:

The three types of population distribution are uniform, random, and clumped.

Uniform distribution is rare. Individuals are evenly spaced and there is fierce competition for resources.

In random distribution, some individuals are close together, and some are spread apart. This occurs when there are sufficient resources available.

In clumped distribution individuals are clustered around patchy resources. This is the most common type of distribution.

WILL RANK BRAINIEST HELP ASAP!!!

Answers

The explanation 'mRNA is single-stranded and is involved in transcription' accurately describes the structure of nucleic acid and how it is involved in the process of gene expression.

During gene transcription, a fragment of DNA called gene is used as template to create a complementary messenger RNA (mRNA).

Subsequently, this mRNA is then used as template to generate a protein by a process called translation.

This mRNA is a single-stranded nucleic acid instead of a double-stranded nucleic acid (like DNA).

In conclusion, the explanation 'mRNA is single-stranded and is involved in transcription' accurately describes the structure of nucleic acid and how it is involved in the process of gene expression.

What happens during the 4 stages of mitosis

Answers

Answer:

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope ...

Explain the effects of air pollution on several European countries. (Site 1)

Answers

Answer:

Air pollution harms human health and the environment. In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in improved air quality across the region. However, air pollutant concentrations are still too high, and air quality problems persist. A significant proportion of Europe’s population live in areas, especially cities, where exceedances of air quality standards occur: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks. Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants. Reducing air pollution therefore remains important.

Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.

Particulate matter, nitrogen dioxide and ground-level ozone, are now generally recognised as the three pollutants that most significantly affect human health. Long-term and peak exposures to these pollutants range in severity of impact, from impairing the respiratory system to premature death. Around 90 % of city dwellers in Europe are exposed to pollutants at concentrations higher than the air quality levels deemed harmful to health. For example, fine particulate matter (PM2.5) in air has been estimated to reduce life expectancy in the EU by more than eight months. Benzo(a)pyrene is a carcinogenic pollutant of increasing concern, with concentrations being above the threshold set to protect human health in several urban areas, especially in central and eastern Europe.

"Air pollution is causing damage to human health and ecosystems. Large parts of the population do not live in a healthy environment, according to current standards. To get on to a sustainable path, Europe will have to be ambitious and go beyond current legislation."

What causes the cell in living organisms to be different from one another?

Answers

they have different specifications eg. a muscle cell has lots of mitochondria as it needs to do a lot of work, or a neuron has to have a mylin sheath to insulate signals

The cells of different body parts are different from one another because they contain different cell organelles according to the function of that body organ.

What are the different types of cells?

Typically, they achieve this without changing the DNA's sequence. An identical set of genes are present in every cell in an individual (see more on genes).

The specific genes that each type of cell “turns on” determine what proteins the cell will generate. The distinct protein composition of each type of cell enables it to carry out certain functions.

Because they create and accumulate various collections of RNA and protein molecules, the various cell types in a multicellular organism become distinct from one another.

Therefore, because each body part's cells have a unique cell organelle that is exclusive to that body organ's function, they differ from one another.

According to the given question, we need to give one reason why the nutrients in a vegetable patch can be considered an abiotic factor.

As a result of this, we can see that the nutrients in a vegetable patch can be considered as an abiotic factor because they are already decomposed.

10. c

Explanation:

Pro phase is the starting stage of the division where the cell division begins. Spindle fibers  are broken into half and the type of division that is present in gametes is reduction division that is the meiosis. Synapsis occurs during mitosis.

What is synapsis ?

It is defined as the stage in which the pairing of the homologous chromosomes take place.

Chromosomes do not line at the equator as the lining of the chromosomes at the equator occurs on the stage of mitosis where it is possible to see the V,J and L shapes of the paired chromosomes. After this stage the exchange of genetic material takes place.Chromatin do not change into chromosomes in the metaphase.

Mitosis is present only to make the duplicate copies of the cell. The identical daughter cells are made when the division of mitosis is taking place in the cell. Chromosomes are first visible in the prophase. A centromere holds two sister chromatids together.

In meiosis crossing over takes place in anaphase 1.

equation of gaseous exchange in plants​

Answers

Answer:

See the answer below

Explanation:

Gaseous exchange in plants involves the entering of oxygen and the exit of carbon dioxide in its place. It is an important process that helps sustains the life of plants, just like every other living organism. The oxygen that enters is utilized in the process of respiration during which carbohydrates are broken down to unlock their energy for metabolic activities.

Oxygen usually diffuses-in through the stomata while the carbon dioxide diffuses in the opposite direction. The summary of the gaseous exchange is summarized in the equation below:

  Glucose (food) + Oxygen ---------> Carbon dioxide + water + energy
