Answer:

An atom is composed of two regions: the nucleus, which is in the center of the atom and contains protons and neutrons, and the outer region of the atom, which holds its electrons in orbit around the nucleus.

The space surrounding the nucleus of an atom contains electrons.

Negatively charged electrons are subatomic particles that orbit the nucleus of an atom at a particular energy level, or electron shell. Compared to the other particles inside the nucleus, protons and neutrons, they are very light and small. Despite having much less mass than protons and neutrons, electrons play an important role in determining the general behavior and characteristics of atoms.

The configuration of electrons in an atom's electron shell determines its chemical structure and reactivity. Depending on how far they are from the nucleus, electrons reside in different energy levels, with the maximum number of electrons allowed in each level.

Explanation:

Cancer cells divide without a 'go' signal. Normal cells cease dividing when DNA is damaged, but cancer cells continue. 'Daughter' cells with aberrant DNA or chromosomal numbers result.

Cancer cells are able to divide even if they have not received the signal that says "all clear." Cancer cells, on the other hand, will continue to divide even in the face of genetic (DNA) damage, which causes normal cells to cease dividing. "Daughter" cells are the end product of this process, and they are characterized by aberrant DNA as well as abnormal numbers of chromosomes.

It is possible for cancer cells to detach from the primary tumor and migrate through the circulatory or lymphatic systems to other parts of the body, where they can then form new tumors after emerging from the blood or lymph vessels. This process is known as metastasis. Cancer is a disease that is created when cells divide without control and spread into the tissues that are in close proximity to them.

Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.

Answer:

An ecosystem consists of a community of organisms together with their physical environment. In ecosystems, both matter and energy are conserved. Energy flows through the system usually from light to heat while matter is recycled.

Answer:

Temperature Regulation

Answer:

1.) Coughing involves a quick contraction of the diaphragm muscle, forcing air

through the respiratory pathway, and dislodging mucus or other harmful

particles

3.) Cilia function like a filter, trapping dust and pollen in the nose,

4.) Mucus traps bacteria and viruses to be removed or swallowed.

Explanation:

Coughing involves a quick contraction of the diaphragm muscle, forcing air out while the cilia act like a filter, trapping dust and pollen in the nose. Mucus traps bacteria and viruses to remove or swallow. So, the correct options are A, C and D.

The respiratory system is defined as the network of organs and tissues that help us breathe which includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system where these parts work together to move oxygen throughout the body and clear out waste gases like carbon dioxide.

Respiratory system works in that way with the immune system by keeping the human from getting sick by bacteria and viruses are removed or swallowed by mucus, while the cilia act like a filter, trapping dust and pollen in the nose.

Thus, coughing involves a quick contraction of the diaphragm muscle, forcing air out while the cilia act like a filter, trapping dust and pollen in the nose. Mucus traps bacteria and viruses to remove or swallow. So, the correct options are A, C and D.

Answer:

Embryo provides information about their ancestors.

Explanation:

Embryonic development retrace evolutionary steps because embryo provides evidence for evolution as embryo formation in widely-divergent groups of organisms are conserved. This embryo provides information that leads to their ancestors from which they evolve so we can say that embryonic development provides evidence for evolution of an organism.

Answer:

The correct answer would be - a decrease in the numbers of RBCs will lead to a decrease in the ability for gas exchange in a person.

Explanation:

In the case of anemia, there would be a decrease in the number of RBCs that might be due to increased destruction of these cells, or low production of RBCs, that transporting oxygen and carbon dioxide affects the ability for gas exchange in an individual.

RBCs carry and transport oxygen to various body parts and then carry back carbon dioxide from different parts of the body to the lungs for gaseous exchange but with less number of RBCs leads to impair or decreased gas exchange in the case of anemia.

Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.

Any solvent can undergo the process of osmosis including gases and supercritical liquids.

Let us have a detailed look at the different types and effects of osmosis in detail.
