Answer:

The small number behind each element symbol designates the number of atoms of each element in a chemical formula. If there is no number, it is assumed there is only one of those elements. A large number in front of a compound designates how many units there are of that compound.

Answer:

b gametes

Explanation:

These sex cells are also called reproductive cells or gametes.

Variations in species help them to adapt themselves to that particular environment and give them a chance of survival. For example, thermophilic bacteria are variants that are resistant to extreme temperature. They have a chance of survival in high temperate zones while others die.

Answer:

Blood carries oxygen to the cells throughout your body to keep them healthy. Explanation:

Hypoxemia can cause mild problems such as headaches and shortness of breath. In severe cases, it can interfere with heart and brain function. Hypoxemia that causes low oxygen levels in your body's tissues is called hypoxia.

The outcome of lack of oxygen To maintain your body's cells healthy, blood provides oxygen to every cell.

The smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The substances that enter and leave the cell are governed by the cell membrane, which encloses the cell.

There are two different types of cells: prokaryotic cells, which lack a nucleus but still have a nucleoid area, and eukaryotic cells, which have a nucleus. Eukaryotes can either be single-celled or multicellular, in contrast to prokaryotes, which are single-celled organisms.

From bacteria to humans, cells give all living things their structure and functionality. They are regarded as the tiniest form of life by scientists.

Thus,  To maintain your body's cells healthy, blood provides oxygen to every cell.

Natural selection and selective breeding can cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason, selective breeding is sometimes called artificial selection.

Answer:

B recycyling

Explanation:

The resources which are present in a limited amount and must be used carefully are called nonrenewable resources.  For example - petrol, coal, and etc.

The correct answer is B.

There are many activities that help humans preserve non-renewable resources because they are present in a very limited amount.

For example, the amount of coal is limited on the earth. we have to reuse it and recycle it and its end product.

Hence, the correct option is B that is recycling.

Answer:An inherited trait is one that is genetically determined. Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and environment.

Explanation:

Answer:

Recombination Of Genes

Explanation:

Recombination of the gene's evolutionary mechanism increases inheritable variations, hence option A is correct.

Gene flow, recombination, and mutation are mechanisms that enhance genetic variety. There are more mechanisms that work to promote genetic diversity, but fewer that work to reduce genetic diversity.

Demographic bottlenecks tend to decrease genetic diversity by intensifying genetic drift, but because genetic drift is random and has local impacts owing to recombination, mutation, and selection, the overall impact may vary along the genome.

Because it introduces new variety into the population, the mutation is the only mechanism of evolution mentioned that increases the amount of genetic variation. Genetic drift is the haphazard loss of genetic variation over time.

Therefore, option A is correct.

Answer:

The characters learned to respect each other enough to discuss why the boy tried to grab the purse.

Explanation:

In the short story "Thank You, Ma'am" by Langston Hughes, a young, hungry boy was about to rob a woman of her purse. But as circumstances would turn out, he was unsuccessful in that attempt but then learned a valuable lesson from the very woman he had targeted.

One conflict that was resolved in the resolution was that both of the characters, Mrs. Luella Bates Washington Jones and Roger, learned to respect one another. By her act of inviting him to her home and preparing food for him, Roger also came to respect and trust the woman. It was this faith that helped them discuss the events that led to Roger's failed attempt of robbing Mrs. Jones, and Roger left the house with a sense of appreciation and a change of heart.

Thus, the correct answer is the first option.

Answer:

Element's number of atoms in a chemical formula

Explanation:

The small number behind each element symbol indicates each element's number of atoms in a chemical formula. If there is no number, it is assumed there is only one of these elements. A huge numeral in front of a compound designates whereby many units there are of that compound.

Answer:

B

Explanation:

When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between the Geosphere/lithosphere and the atmosphere.

Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.

Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.

The correct option is B.
