The primary function of light absorption by photosystems i and ii is to produce __________.
The primary function of light absorption by photosystems I and ii is to produce a free electron, full of energy.
Photosynthesis is the process by which plants or algae produce oxygen and energy using Sunlight, carbon dioxide, and water.
Photosystem I and photosystem II help plants to absorb light and radiation. The absorption of light in Photosystem II and then in I excites a free electron which is then passed by an electron transport chain.
This electron transport chain uses the energy of electrons to form a protein gradient that can be used as an energy source.

choose the incorrect statement. when a small fish (e.g. a goldfish) is placed in water with a temperature gradient, it will explore the environment until its optimum temperature changes to the temperature of the water. after an ectotherm has acclimated to a lower temperature, its critical temperature is lower even though its optimal metabolic rate is the same. terrestrial ectotherms rely primarily on behavioral thermoregulation to help them achieve their optimal metabolic rates. a terrestrial ectotherm can achieve a body temperature higher than ambient air temperature using heat gain by radiation or by conduction.
When a small fish (e.g. a goldfish) is placed in water with a temperature gradient, it will explore the environment until its optimum temperature changes to the temperature of the water.
Temperature gradient- The only difference in temperature across a certain distance between two sites is referred to as a temperature gradient. Between the two places, there are variations in air pressure because of the temperature differential. As the atmosphere strives to equalize the air pressure, the air pressure difference causes winds to develop.
Optimum Temperature- The temperature at which a process, such the growth of a particular organism or the activity of an enzyme, is best carried out.

Mutation
What is Mutation?
A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Hollywood has used the term "mutation" to describe a variety of biological processes, but in reality, it simply refers to a mistake that occurs during the copying of DNA.
Some of that is merely the background noise that DNA copying is imperfect, which is something to be thankful for since without it, evolution would not be possible.
However, factors like radiation or toxins can also cause mutation in a way that raises the chance of malignancies or birth problems. But it's actually rather easy; the DNA sequence has essentially been intentionally misspelled. That is a change.

amino acids are those amino acids that do not need to be obtained from the diet because the body is capable of synthesizing (producing) them.
Nonessential amino acids are those amino acids that do not need to be obtained from the diet because the body is capable of synthesizing (producing) them.
Nonessential implies that our bodies can make the amino acid even if we don't get it from food. Alanine, aspartic acid, arginine, serine, asparagine, cysteine, glycine, glutamine, glutamic acid, proline, and tyrosine are examples of nonessential amino acids.
Nonessential amino acids help with tissue development and repair, immunity, the formation of red blood cells, and hormone synthesis. However, unlike essential amino acids, a healthy body can produce these proteins if provided with good protein sources containing essential amino acids.

Compare the species richness, species diversity, and species evenness in the two areas. Describe two factors you think
could account for the differences in species richness/diversity/evenness in the two areas.
!!Please answer in 2 sentences!!
Species richness and species diversity are two crucial metrics ecologists employ to define the make-up of a community.
A community's species richness is determined by how many distinct species it contains. E.g., the second community would have a substantially higher species richness than the first if we identified 30 species in one community and 300 species in another.Near the equator, where there is a high concentration of solar energy, warm temperatures, abundant rainfall, and little seasonal variation, are typically where communities with the highest species richness can be found. Near the poles, which receive less solar energy and are colder, drier, and less conducive to life, are communities with the lowest species richness.The complexity of a community is gauged by its species diversity. It depends on both the community's species richness (the number of different species present) and species evenness (the relative abundances of those species).Greater species diversity would be seen in a forest community with 20 distinct tree species than one with only 5 distinct tree species .Numerous interrelated biotic (living things) and abiotic (non-living) factors contribute to the structure of a community (living organism-related): the climate of the communitythe location of the community geographicallyThe environment's heterogeneity (patchiness)how often disturbances or disruptive incidents occurinterspecies interactions.Learn more about species diversity here:

infiltrating s100a8 myeloid cells promote metastatic spread of human breast cancer and predict poor clinical outcome
The mechanisms of metastasizing breast cancer are complex. the goal was to identify tumor-induced stromal modifications that affect metastatic cell behavior, and function as better marks for therapy.
Dual-species gene expression analysis was performed to identify stromal changes in cancer-bearing tissue for three different metastatic Breast cancer xenografts. In pre-clinical models of Breast cancer, the systemic need for S100A8+ myeloid cells-including myeloid-derived suppressor cells (MDSCs)-was stimulated by tumor-derived factors.The need for S100A8+ myeloid cells was reduced by inhibition of tumor-derived factors leading to fewer metastases and fewer primary tumors. Those myeloid-derived suppressor cells possess the ability to suppress T cell accumulation upon co-culture.
The release of macrophage inhibitory factors activates the need for S100A8+ myeloid cells systemically. Inhibition of MIF leads to delays in lower metastatic burden and tumor growth. In enhancing cancer progression independent of their suppressive activity on T cells, there is the recruitment of S100A8+ myeloid cells to secondary sites in xenograft models and primary tumors of Breast cancer.
