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.

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 ...

Answer:

Nutrients can come from dead plants that have decomposed. Available nutrients affect the carrying capacity of garden plants. Nutrients are mostly obtained from the soil.

One of the reasons that nutrients in a vegetable patch might be considered abiotic is:

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.

An abiotic factor in an ecosystem is any non living thing which has a direct (or indirect) impact on the living things in an ecosystem.

Explanation:

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.

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.

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.

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.

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.

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."

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

Or better still;
