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.
What is 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.

Please help meeeeeeeeeeeeeeeeeeeeeeeeeee
Answer:
1.) The two gametes found in humans are the sperm and the ova.
2.) Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
3.) Because the alleles that the mother and the father carry are mixed together in the offspring.
4.) Because it only introduces genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.

how does the nitrogen cycle start from nitrites and end with nitrates? (full answer)
Explanation:
The nitrogen cycle seems to be the nitrogen form of recycling, that requires fixing of nitrogen, Teodoro mamoncillo, nitrogen removal, and deionization. The mechanism whereby the nitrogen and nitrites are subsequently converted to nitrogen fixation is denitrification.

Alternative forms of energy tend to be more expensive than burning fossil fuels. It is true.
What is fossil fuel?
Fossil fuels has been result of the biological processes as heat and pressure from the Earth's crust that decomposed these organisms into one of the three main kinds of fuel and these are oil which is also called petroleum, natural gas, or coal.
The origin of the fossil fuels has the anaerobic decomposition of the buried lifeless organisms, that containing natural molecules is created through photosynthesis. The conversion from those materials to excessive-carbon fossil fuels commonly require a geological method of millions of years.
Biological methods are defined as the processes that are very crucial for an organism to live, as well as that shape its capacities for interacting with its surroundings. The organic processes has been made of many chemical reactions or the different events that use to concerned within the persistence as well as the transformation of lifestyles forms.
Therefore, Biological approaches either aerobic or the anaerobic which is based upon the environmental necessities of the microbial consortia.

Is glucose more or less complex than the rest of the biomolecules? Explain.
Answer:
Less complex.
Explanation:
Glucose is both a monomer and simple sugar.
Glucose is a monosaccharide. It is a biomolecule. It is less complex than the rest of the biomolecules, such as proteins, lipids, and other complex carbohydrates like glycogen.
What is a biomolecule?
Biomolecules are present inside the cell. Carbohydrates, proteins, and lipids are some examples of biomolecules. Carbohydrates are divided into monosaccharides, disaccharides, and polysaccharides.
A monosaccharide has a single unit. Examples are glucose, fructose, etc. A disaccharide consists of two units. An example is maltose. Maltose is made up of two units of glucose connected by a glycosidic bond. An example of a polysaccharide is glycogen. Multiple sugar units are connected by glycosidic bonds to form glycogen. It is a storage product.
Carbohydrates are present on our cell surface as peptidoglycan. Protein is a biomolecule that is made up of amino acid monomers. They make the different structures of a cell, such as actin fibers, etc. Lipid is made up of hydrogen and carbon. Examples are cholesterol, phospholipids, etc.
Hence, in comparison to all other biomolecules, glucose is the simplest.

what’s the chemical reaction for the digestion of fats.
Answer: The chemical reaction for the digestion of fats is when A triester is produced through the chemical reaction of three fatty acid molecules with glycerol, a molecule that contains three hydroxyl groups. When fats are broken down these fatty acid chains and glycerol are free for the body to use.
Explanation:
Lipids (fats and oils)
Lipase enzymes break down fat into fatty acids and glycerol. Digestion of fat in the small intestine is helped by bile, made in the liver. Bile breaks the fat into small droplets that are easier for the lipase enzymes to work on. Bile is not an enzyme.

What the Viceroy's color pattern evolved?The Viceroy's color pattern has been evolved because the natural selection favoured them. The viceroy butterfly camouflage as the monarch butterfly as well as the exhibit Mullerian mimicry where as these two toxic species has the mimic each other for their benefit and by time natural selection has been favoured these.
Natural selection has been the process by which the reproductively fitest has the populations of the living organisms survive, adapt and change. The viceroy butterfly has the brush-footed butterfly having the dark orange colour with the black veins and row of the white spots on the border of its wings.
Monarch butterfly has the same as that of the viceroy except that it has the black horizontal stripes that has cross the bottom of its back wings. Species has refers to the group of the organisms which have the similar features and which are able to be interbreed to produce the viable and the fertile offspring.
Therefore, reproductive isolation prevents interbreeding between members of different species. It includes a collection of behavioral, evolutionary, and physiological processes.
