The primary function of light absorption by photosystems i and ii is to produce __________.
Answers
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.

suppose you discover a cell that is 200 micrometers in diameter. upon closer examination, you find that the dna is not housed within a nucleus and you find no other membrane-bound organelles. this organism is most properly categorized as:
Answers
If a cell is found to have no nucleus and no membrane bound organelles on observation then it is categorized as a prokaryotic cell.
Prokaryotic cell: Any cell that does not have a delineated nucleus or membrane-bound organelles. All other forms of life are eukaryotic, whereas organisms in the domains Bacteria and Archaea are based on the prokaryotic cell. Prokaryotic species, on the other hand, are exceedingly prevalent and account for a large portion of the biomass on Earth.The tiniest eukaryotic cells are substantially larger than prokaryotic cells. Prokaryotic cells are often smaller because they lack enough DNA to produce the proteins required to form an ultra-efficient membrane.The nucleoid region, which is an atypically shaped area that houses the cell's DNA and is not encased in a nuclear envelope, is present in prokaryotic cells.A prokaryote's cytosol is where all of the organism's responses take place.Hence, the correct answer is prokaryotic cell.

Answers
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.

bone-targeted delivery of tgf-beta type 1 receptor inhibitor rescues uncoupled bone remodeling in camurati-engelmann disease.
Answers
Camurati-Engelmann disease (CED) is a genetic bone-modelling disorder mainly caused by mutations in the gene that encodes transforming growth factor-β1 (TGF-β1). To achieve bone-targeted delivery of TR1I, it is designed a new drug that conjugated TR1I and bisphosphonate through a metabolically cleavable linker. It is characterized by increased bone density primarily affecting the long bones of the arms and legs and the skull.
CED is a rare bone dysplasia characterized by diffuse diaphyseal osteosclerosis. Skull base involvement in CED can result in hypopituitarism but is seldom reported. Our objective was to report a patient with acquired hypopituitarism due to CED and assess the management challenges. The thickening of these bones leads to pain, a waddling gait, muscle weakness, and extreme fatigue.

The correct answer is option b) 5, 1, 2, 3, 7, 4, 6.
The six stages of viral replication include attachment, penetration, uncoating, replication, assembly, and release.
A virus attaches to and inserts its genetic material into a host cell during attachment and penetration.
During uncoating, replication, and assembly, the viral DNA or RNA integrates into the host cell's genetic material, prompting it to replicate the viral genome.
During the release, the newly developed viruses are expelled from the host cell by forcing the cell to disintegrate, waiting for the cell to die suddenly, or budding off through the cell membrane.

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!!
Answers
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
Answers
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.

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.

Answers
Answer:
The primary spermatocyte of prophase 1 contain double amount of DNA (3.57×2= 7.14pg) as it is diploid in nature.
Explanation:
Most DNA in mature human sperm is bound to protamine, as somatic histones are replaced during spermiogenesis. However, biochemical analyses of human sperm proteins indicate retention of some histones resulting in a nuclear protein composition that is about 90% protamine and 10% histone.
Primary spermatocyte produces four spermatids. During spermatogenesis there are two cellular divisions, but only one replication of DNA so that each spermatid has 23 chromosomes (haploid), one from each pair in the original primary spermatocyte. It begins with a diploid spermatogonium in the seminiferous tubules, which divides mitotically to produce two diploid primary spermatocytes.
