Does the formation of sperm is more in low temperature???
Answer:
Sperm production is a process that's sensitive to heat. Ideally, sperm production occurs around 93.2ºF, which is about 5ºF below normal body temperature. This is why the testes hang below the body to keep the temperature a bit lower.

Many soil-dwelling bacteria produce molecules that can be naturally synthesized and kill other species of bacteria. What are these bacteria-killing molecules called?.
These molecules that kill bacteria are known as anti-biotics.
Antibiotic literally translates to "against bacteria". It is a specific class of antimicrobial agent that works to kill bacteria. The use of antibiotic drugs is common in the treatment and prevention of bacterial infections since they are the most effective type of antibacterial agent. Bacterial growth may be prevented or killed by them.They either destroy the germs or make it difficult for them to proliferate and flourish.There are several ways to take antibiotics:Orally (by mouth): These could be tablets, capsules, or liquids.Topically: You might apply this to your skin as a cream, spray, or ointment. Additionally, it can be ear drops, eye drops, or eye ointment. Intravenously: an injection.So, the answer is antibiotics.

double histidine based epr measurements at physiological temperatures permit site-specific elucidation of hidden dynamics in enzymes
Double Histidine Based EPR Measurements at Physiological Temperatures Permit Site‐Specific Elucidation of Hidden Dynamics in Enzymes is a research paper written by Kevin Singewald and Xiaowei Bogetti.
What is the abstract?All biological activities revolve around protein dynamics. In this study, we use the dHis-Cu(II)NTA motif to gather site-specific data on dynamics for both a ß-sheet and a -helix site of GB1, the protein G immunoglobulin binding domain. Our CW-EPR measurements revealed spectral characteristics that agreed with both the general rigidity of GB1 and the expectations made by molecular dynamics simulations. With the use of this knowledge, we demonstrate how this method may be used to clarify the role of dynamics in substrate binding of a functionally essential -helix in human glutathione transferase A1-1 (hGSTA1-1). We find that the helix has two dynamical modes. The inclusion of the inhibitors GS-Met and GS-Hex caused the structure of hGSTA1-1 to favor the more rigid active state, but the faster mode may help with the search.

Darwin was well aware of what effect his theory of evolution would have on the public and on the church of England.
The statement is true.
Darwin's groundbreaking theory was that new species do not originate from God's eternally unchangeable creation but rather develop organically via a process of evolution.
Darwin held off on releasing his findings for several decades while he gathered more evidence because he was fully aware of the effect his theory of evolution would have on the general public and the Church of England. He suggested that natural populations can also change after citing selective breeding of tamed animals as proof that groupings of creatures can undergo change.

the transcription factor zeb2 regulates development of conventional and plasmacytoid dcs by repressing id2.
Answer: Zeb2 controls commitment to both the cDC2 and pDC lineages by inhibiting Id2.
Explanation: Pre-pDCs give rise to plasmacytoid dendritic cells, whereas pre-cDCs, which are lineage-committed, give rise to the two lineages of conventional dendritic cells (cDC1 and cDC2). The formation of pDCs and cDC1s has been linked to a number of transcription factors , but it is uncertain whether TFs are necessary for pre-cDCs to commit to the cDC2 lineage at an early stage. From the pre-pDC and pre-cDC stage on, Zeb2 was expressed, and it was significantly expressed in mature pDCs and cDC2s. Id2 was discovered to be a specific target of Zeb2 by chromatin immunoprecipitation research. We thus deduce that Zeb2 controls commitment to both the cDC2 and pDC lineages by inhibiting Id2.

What structural property of dna gave watson and crick the idea that dna replication was likely to proceed via a semiconservative mechanism?.
The complementary nature of base pairing between the two strands of DNA is the structural property of DNA that gave Watson and Crick the idea that DNA replication was likely to proceed via a semiconservative mechanism.
Watson and Crick are the two scientists known for coming up with the model of DNA, the hereditary molecule. DNA is a double helix structure made up of two strands. These strands are held together by the complementary pairing of the 4 nucleotide bases.
In the DNA, adenine from one strand pairs with thymine from the other strand. Guanine from one strand pairs with cytosine. This complementary pairing is the reason that Watson and Crick proposed the semi-conservative model for DNA replication.
In the semi-conservative model, each strand of DNA acts as a template strand from which a new strand is made.
Although a part of your question is missing, you might be referring to this question:
What structural property of DNA gave Watson and Crick the idea that DNA replication was likely to proceed via a semiconservative mechanism?

what term describes the measure of how quickly a carbohydrate will raise an individual’s glucose levels when consumed on its own, irrespective of the amount eaten?
Glycaemic index is used to measure the amount of carbohydrates that will raise an individual’s glucose levels.
Glucose is a sweet sugar and belongs to the class of carbohydrates.
It is obtained from food that we consume and in response our body utilizes it for energy purposes.
Glycaemic index of food refers to the time period during which carbohydrates are disintegrated and absorbed in the blood.
If GI is higher then it will enter the blood more quickly as compared to lower GI levels.
Higher GI levels means higher glucose levels in the blood and vice versa.
