In animals, the solute balance of the plasma surrounding blood cells must be carefully maintained so that the blood cells are not affected by changes in fluid or solute balance. If the plasma becomes hypotonic compared with the blood cells, what will be the effect
Answers
Blood cells would osmotically absorb water by osmosis if the plasma around them became hypotonic relative to the blood cells.
Thus, osmosis is the transfer of water molecules from a region with low concentrations of solutes to a region with high concentrations of solutes across a semipermeable membrane. In this instance, water molecules will transfer from the plasma into the blood cells in an effort to equalize the solute concentrations as the plasma is hypotonic (lower solute concentration) than the blood cells.
The outcome is hemolysis, which causes the blood cells to expand and perhaps rupture. Organisms have systems to control the osmotic balance of their plasma in order to maintain the correct solute balance and avoid such negative consequences.

if you consume one molecule of pyruvate , how many ATP molecules you are going to produce ?
1 NADH -> 3 ATP
1 FADH2 -> 2 ATP
Answers
A single molecule of pyruvate will generate 15 ATP molecules.
Pyruvate is an important chemical constituent according to biochemical science. It is the molecule that is produced from glycolysis, a process by which energy is derived from glucose. The carboxylate group of pyruvate is removed as carbon dioxide. The synthesized acetyl group is stimulated through its association with Coenzyme-A, thus, producing Acetyl Coenzyme-A.
The TCA cycle generates 15 ATP molecules through oxidation of Acetyl Co-A. Through oxidative decarboxylation as well as Krebs cycle, a single molecule of pyruvate (containing 3 Carbon atoms) gives rise to 4 molecules of NADH, a single molecule of FADH2 as well as one molecule of ATP.

Answers
The given statement "in general, humans’ effects on ecosystems lead to an increase in genetic diversity" is False.
In general, humans' effects on ecosystems do not necessarily lead to an increase in genetic diversity. Human activities such as habitat destruction, pollution, introduction of non-native species, and overexploitation of resources can actually result in a decrease in genetic diversity within ecosystems.
These activities can lead to the loss of habitat and fragmentation of populations, limiting gene flow and increasing the risk of inbreeding.
Additionally, human-driven selection pressures may favor certain traits or populations, leading to the loss of genetic variation. Overall, human activities often contribute to the reduction of genetic diversity in ecosystems, which can have negative implications for the long-term viability and resilience of species and ecosystems.

enes that are close together in the same chromosome belong to the same _____ group.
Answers
The Genes that are close together in the same chromosome belong to the same linkage group. A linkage group is a set of genes that are located close to each other on a chromosome and are often inherited together.
The closer two genes are on a chromosome, the more likely they are to be inherited together, and the less likely they are to undergo genetic recombination. Genetic recombination is the process by which chromosomes exchange genetic material during cell division. If two genes are far apart on a chromosome, they are more likely to undergo genetic recombination, resulting in the formation of new combinations of alleles. On the other hand, genes that are close together on a chromosome are more likely to be inherited together and will not undergo genetic recombination as frequently. Linkage groups are an important concept in genetics, as they help to explain patterns of inheritance and genetic variation. By studying the linkage of genes on chromosomes, scientists can better understand the mechanisms of inheritance and evolution. Additionally, linkage analysis can be used in genetic research to identify genes associated with diseases and traits.

During this era the surface of the Earth was like popular visions about Hades: oceans of liquid rock, boiling sulfur, and impact craters everywhere, meanwhile, during, for example, the Cretaceous period, Earth's land assembled essentially into two continents, Laurasia in the north and Gondwana in the south. These were almost completely separated by the equatorial Tethys seaway, and the various segments of Laurasia and Gondwana had already started to rift apart, and there were oceans of seawater, teeming with life such as Mosasaurs and Ammonites.

oceans, the atmosphere, and groundwater are all ________ in the water cycle.
Answers
Oceans, the atmosphere, and groundwater are all reservoirs in the water cycle.
What is a water cycle?The water cycle, also known as the hydrologic cycle, is the continuous process by which water moves through the Earth's atmosphere, land, and oceans. Water evaporates from oceans, lakes, and other bodies of water and is transported to the atmosphere in the form of water vapor. The water vapor then condenses and falls back to the Earth's surface as precipitation, such as rain or snow.
Some of the precipitation is absorbed by plants and returned to the atmosphere through the process of transpiration, while the rest flows over the land and into rivers and streams, eventually making its way back to the oceans. Some of the water that falls to the Earth's surface also infiltrates the soil and becomes part of the groundwater system. The water in these reservoirs is constantly moving and being recycled through the water cycle.

The pedigree below depicts a dominant trait. What is the genotype of individual I-1 (use the letter A for a dominant allele and a for a recessive allele)? How did you come to this conclusion? Using your best grammar, write 3-5 sentences.
Answers
Individual I-1 is heterozygous (Aa) for the dominant trait. This is because they have a child (II-1) who is homozygous recessive (aa). The only way for this to happen is if individual I-1 is heterozygous.
What is the conclusion on the pedigree?Pedigree analysis: A pedigree is a diagram that shows the inheritance of a trait from parents to offspring. In this pedigree, the dominant trait is represented by a solid symbol and the recessive trait is represented by an open symbol.
Genotype: The genotype of an individual is their genetic makeup, or the combination of alleles that they have for a particular trait. The phenotype of an individual is their physical appearance, which is determined by their genotype and the environment.
Heterozygous: An individual is heterozygous for a trait if they have one dominant allele and one recessive allele. This means that they have the potential to express the dominant trait, but they may also express the recessive trait if they are in an environment that is not favorable for the dominant trait.
Homozygous: An individual is homozygous for a trait if they have two copies of the same allele for that trait. This means that they will always express the trait, regardless of the environment.

Many mountains have a tree line, which is an imaginary line above which trees will not grow. Hypothesize why some mountains have tree lines and what the trees at the tree line might look like.
Answers
The tree line can be defined as the imaginary line above which the pressure and temperature conditions are not suitable for the trees to grow. As a result of the decreased temperature, pressure and lack of moisture, the trees stop growing at the tree line. This results in the formation of forest with a canopy (closed).
This closed canopy is representative of the end of the height bearing the suitable climatic and atmospheric conditions required for the growth of trees and plants.
The trees do not grow beyond the tree line because of the unsuitable temperature and pressure. The trees at the tree line form a closed canopy.

In an experiment, cells were isolated from an aquatic plant and suspended in pond water, a sucrose sugar solution, or distilled water. All of the cells were then viewed under a microscope. Compared with the cell in the pond water, the cell in the sugar solution appeared shriveled, and the cell in the distilled water appeared inflated. The results of the experiment are represented in figure 1.
Answers
The cell suspended in the sugar solution (hypertonic) experienced a net loss of water, but the cell suspended in the distilled water (hypotonic) saw a net gain.
A cell will lose volume if it is submerged in a hypertonic solution (sugar) because there will be a net flow of water out of the cell. A cell will increase volume if it is submerged in a hypotonic solution (distilled water) because there will be a net flow of water entering the cell. When a cell is submerged in an isotonic solution, there is no net water movement into or out of the cell, and the volume of the cell stays constant.
