What provides evidence of an increase in animal species at the same time that atmospheric oxygen concentrations increased?
ts fossil records but i need an explination
Answers
Answer:
Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.
Explanation:
A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.
If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.

What would cause a change in the phenotype of the offspring that was NOT present in the parent?
Answers
Answer:
Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. Often, it is impossible to determine which two alleles of a gene are present within an organism's chromosomes based solely on the outward appearance of that organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.

An El Nino scenario develops when east winds blow less strongly than usual and surface water in the equatorial Pacific warms up more than usual.
La Nina is the name for the adverse situation. The east winds are stronger and the ocean is cooler than typical during this ENSO phase. Every three to five years, el Ninos typically occur.
One example is data produced by radar altimetry, which is used to monitor the El Nino global climatological event. El Nino is a term used to describe a periodic weakening of the trade winds and warming of the equatorial Pacific Ocean's surface layers.

Among the ingredients of a lipstick are beeswax, carnauba wax, hydrogenated vegetable oils, and capric triglyceride. What types of lipids have been used
Answers
Based on the ingredients listed, it is clear that lipids have been used in the formulation of the lipstick. Lipids are a class of organic molecules that are characterized by their insolubility in water and their solubility in nonpolar solvents. They include fats, oils, waxes, phospholipids, and sterols.
- Carnauba wax: Carnauba wax is another natural wax that is derived from the leaves of the carnauba palm. It is composed primarily of esters of fatty acids and long-chain alcohols, similar to beeswax.
- Hydrogenated vegetable oils: Hydrogenated vegetable oils are oils that have been chemically modified to be more solid at room temperature. They are composed primarily of triglycerides, which are a type of lipid that consists of three fatty acid molecules attached to a glycerol molecule.
Hydrogenated vegetable oils are triglycerides where unsaturated fatty acids have been converted to saturated fatty acids through hydrogenation. Capric triglyceride is a specific type of triglyceride derived from capric acid, a medium-chain fatty acid. These lipids contribute to the texture, consistency, and moisturizing properties of the lipstick.

What are Elements?A chemical element is a species of atoms, including the pure substance made entirely of that species, that have a specific number of protons in their nuclei.
Chemical elements, in contrast to chemical compounds, cannot be reduced by any chemical process into simpler molecules. An element's atomic number, denoted by the symbol Z, is the attribute that distinguishes it from other elements; all atoms with the same atomic number belong to the same element.
Chemical elements make up the majority of the universe's baryonic stuff (among rare exceptions are neutron stars). Atoms are rearranged into new compounds linked together by chemical bonds when various elements undergo chemical reactions.

Explanation:
if a pollen spore is unable to carry s proteins in its pollen coat, can plants still prevent the germination of this pollen if it is too genetically similar?
Answers
Plants have evolved various mechanisms to prevent self-fertilization and to promote outcrossing, which can increase genetic diversity and increase the fitness of the offspring. One mechanism is the prevention of germination of genetically similar pollen.
Plants' ability to avoid self-fertilization has been linked to the pollen coat's S-protein content. These proteins adhere to the female stigma, where the plant's self-incompatibility mechanism detects them. The self-incompatibility system will block pollen germination if it determines that the pollen and the female plant are too genetically similar.
However, the plant's self-incompatibility system might not be able to identify a pollen spore as being too genetically similar if it is unable to contain S-proteins in its pollen coat. In this situation, it's possible that the pollen will grow, fertilize the ovules, and cause self-fertilization.

Which feature of the model represents stored chemical energy
Answers
The sugar molecule represents the most stored chemical energy. Thus, the correct answer is Option B.
Sugar (glucose, C₆H₁₂O₆) is a biological molecule that stores energy in its chemical bonds, not the molecule that initiates the process of cellular respiration During cellular respiration, glucose is broken down in a series of chemical reactions to produce energy ATP (adenosine triphosphate).
The process of cellular respiration begins at the stage of glycolysis, where glucose in the cytoplasm of the cell is partially broken down into pyruvate molecules and then the pyruvate molecules are broken down again in the presence or production of oxygen (aerobic respiration). fermentation in the absence of oxygen depending on whether oxygen is present
During aerobic respiration, pyruvate enters mitochondria and undergoes the citric acid cycle (also known as the Krebs cycle) and the electron transport chain These processes release energy from glucose chemical bonds to produce more ATP.
Therefore, sugar (glucose), although it stores energy in its chemical bonds, is not the molecule that initiates cellular respiration. Instead, during cell respiration, glucose is broken down and energy is released in the form of ATP.

if a cell starts out in g2 phase with 12 chromosomes, how many chromosomes would you expect in each of the daughter cells if one of the chromosomes failed to separate in anaphase?

When a cell starts in G2 phase with 12 chromosomes, chromosomes that would be in each of daughter cells if one chromosomes failed to separate in anaphase: one daughter cell will have 11 chromosomes and other will have 13.
What happens in G2 phase?G2 phase is a period of rapid cell growth and protein synthesis in which cell prepares itself for mitosis.
If a chromosome fails to separate into two chromatids during anaphase, then both chromatids would travel to the same daughter cell during anaphase. This means that one daughter cell would have an extra chromosome and other daughter cell would be missing a chromosome.

Explain how ecosystems could be impacted from each indicator of climate change:
D.) shifting temperatures and weather patterns have forced some species to move to new locations or to new ecosystems entirely. The migration patterns of some species have also been altered because species must move to comfortable climatic conditions for their survival
Answers
Answer:
There are two main impacts on marine ecosystems from climate change: (a) rise of sea surface temperature; and (b) ocean acidification (due to CO2). Both (a) and (b) will impact on marine life. For example, increased in sea surface temperature caused a shift in distribution of fishes toward poles. Warming will likely affect the successful recruitment of marine organisms. In addition, warming may cause more toxic algal blooms (dinoflagellates and diatoms). Dinoflagellates and diatoms produce toxins which can then be accumulated in seafood organisms via the food chain pathways. Calcifying organisms (e.g. pteropods, corals, and molluscs) would be more vulnerable to changes in ocean acidification.
