Explanation:
Natural selection; Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Weaker animals within a breed being killed off for food for another species, the surviving animals breed and continue the better genes for survival.
Artificial Selection; Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
Corn. Larger growing corn was taken for more growth while smaller were eaten and not continued. Humans decdied the larger pieces were better for food.

alumbraron la dulce oscuridad
de estar juntos y no decirse nada.
Solo las manos se estrecharon tanto
como rompiendo el hierro de la ausencia.
¡Si una nube eclipsara nuestras vidas!
Deja en mi corazón las voces nuevas,
el asalto clarísimo, presente,
de tu persona sobre los paisajes
que hay en mí para el aire de tu vida

Suppose that a cell is unable to replicate its DNA. Which of the following would NOT be present in this cell? ******ONLY ANSWER IF YOU KNOW THE ANSWER GIVING BRAINLIEIST******
Answer:
sister chromatids
Explanation:
Suppose that a cell is unable to replicate its DNA, the structure that will not be present in the cell is sister chromatid.
What is sister chromatid?Sister chromatid refers to replicated chromosome that are genetically identical.
Prior to every cell division, a cell must replicate its DNA in order to have an even distribution of genetic material in the daughter cells.
The result of DNA replication is sister chromatids, which carry individual identical DNA.
Therefore, if a cell is unable to replicate its DNA, the structure that will not be present in the cell is sister chromatid.

how quickly do new epithelial cells reach the surface of the skin?
Answer:
2 weeks to a month
Explanation:
when new skin cells are made, they move from the bottom of the epidermis to the top of the epidermis. This takes about 2 weeks to a month. As the new cells move up, old cells near the top die and rise to the surface of the skin.
The dead cells are what we see on our skin every day.

what is the main difference between humans and seals regarding oxygen stores?
Answer:
Seals store oxygen in their lungs, blood and muscle. Compared to humans, seals have larger lungs because they are also larger animals, but a greater proportion of oxygen is found in the blood rather than in the lungs.

it has caused many to die, yes the government brought that to help with security but it has gotten into Tue hands of those that have no value for human life. Take the case of the Boko harm in surgery in Nigeria, all of them are armed with Ak47's and they use it to kill innocent Nigerians not only that there are series of cases of accidental shootings AND that's how a life is lost.

How are stem cells nurtured to form a tissue/organ?
Answer:
Stem cells have the capacity to proliferate and to differentiate into relatively mature cells of various types. Embryonic stem cells can become any organ in the body and do so when implanted into a blastocyst. In principle, then embryonic stem cells could be used to replace any organ in the body.

Which two fit?
Respiration

Answer:
Explanation:
There are a few types of atoms that can be a part of a plant one day, an animal the next day, and then travel downstream as a part of a river’s water the following day. These atoms can be a part of both living things like plants and animals, as well as non-living things like water, air, and even rocks. The same atoms are recycled over and over in different parts of the Earth. This type of cycle of atoms between living and non-living things is known as a biogeochemical cycle.
All of the atoms that are building blocks of living things are a part of biogeochemical cycles. The most common of these are the carbon and nitrogen cycles.
Tiny atoms of carbon and nitrogen are able to move around the planet through these cycles. For example, an atom of carbon is absorbed from the air into the ocean water where it is used by little floating plankton doing photosynthesis to get the nutrition they need. There is the possibility that this little carbon atom becomes part of the plankton’s skeleton, or a part of the skeleton of the larger animal that eats it, and then part of a sedimentary rock when the living things die and only bones are left behind. Carbon that is a part of rocks and fossil fuels like oil, coal, and natural gas may be held away from the rest of the carbon cycle for a long time. These long-term storage places are called “sinks”. When fossil fuels are burned, carbon that had been underground is sent into the air as carbon dioxide, a greenhouse gas.
Recently, people have been causing these biogeochemical cycles to change. When we cut down forests, make more factories, and drive more cars that burn fossil fuels, the way that carbon and nitrogen move around the Earth changes. These changes add more greenhouse gases in our atmosphere and this causes climate change.
Carbon cycleThe Carbon Cycle
The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle.
Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.
Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.
Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But since the start of the Industrial Revolution about 150 years ago humans have burned so much fuel and released so much carbon dioxide into the air that global climate has risen over one degree Fahrenheit. The atmosphere has not held this much carbon for at least 420,000 years according to data from ice cores. The recent increase in amounts of greenhouse gases such as carbon dioxide is having a significant impact on the warming of our planet.

how do plants and snails affect the CO2 and O2 gases in an aquatic environment
Answer:
Water plants will absorb carbon dioxide for photosynthesis, and some plants will also absorb ammonia (as a source of nitrogen for growth). Aquatic animals like fish and snails absorb oxygen and release carbon dioxide directly into water through specialized structures like gills.
Explanation:
through which pathway are most water and solutes reabsorbed in the kidney tubule?
Answer:
proximal tubuleThe majority of water reabsorption that occurs in the nephron is facilitated by the AQPs. Most of the fluid that is filtered at the glomerulus is then reabsorbed in the proximal tubule and the descending limb of the loop of Henle.
Explanation:
The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle. It can be further classified into the proximal convoluted tubule (PCT) and the proximal straight tubule (PST).
