Answer:how can chemosynthetic organisms help scientists to understand how life developed on earth? for example, temperature, a species may evolve to a temperature change over time. it could alter the food sources available, and then that species would eat that food source and adapt to the energy given off by that source.
Explanation:
Answer:
When oestrogen rises to a high enough level it causes a surge in LH from the pituitary which causes ovulation where an egg is released from the follicle (Day 14 of the cycle). The follicle becomes the corpus luteum and this produces oestrogen and progesterone which inhibit FSH and LH production by the pituitary.
Explanation:
Answer:
30 protein molecules per mRNA molecule
Explanation:
In this problem, it is necessary to have into account that the transcriptional process requires six (6) phosphate bonds to synthesize one (1) codon (i.e, each three nucleotides), and also discards 95% more energy to make mRNA, it means 19 times this amount of energy >> 6 x 19 = 114 bonds. In consequence, transcription requires 120 phosphate bonds (6 + 114 = 120), while translation requires four (4) phosphate bonds per codon. From this deduction, it is possible to find the number of protein molecules synthesized with regard to the energy cost of the translation process and the transcriptional process >>> 120 bonds (transcription) /4 bonds (translation) = 30 protein molecules.
Answer:
b. where movement occurs through arm-over-arm swinging.
Explanation:
Brachiation is a form of locomotion observed in some species of animal that are adapted to arboreal (tree living) life.
<em>This type of locomotion involves the swinging of arms and the suspension of the body to move from trees to trees.</em>
Animals that exhibit brachiation usually have modified body structure with long forelimbs/hook-like fingers and a highly mobile shoulder joints. Examples of such animals include gibbons and siamangs.
The correct option is b.
To detect immunoglobulin m (IgM)antibodies in an acute phase, blood should be collected 7 days after the onset of infection.
- IgM and IgG antibodies to SARS-CoV-2 may both be found shortly after infection. IgG is typically detectable for extended periods of time, but IgM is most effective for diagnosing recent infection and typically becomes undetectable weeks to months after infection.
- IgM antibody detection is frequently viewed as a sign of an acute infection. Due to cross-reactivity with IgM antibodies to other, closely related bacteria or other interfering chemicals, false-positive IgM findings are, nonetheless, frequently observed.
- A positive IgM result may not always indicate an "acute" infection, and additional testing (such as IgG testing) may be required to interpret results because IgM antibodies may be detectable for 2-4 months (or longer) after disease resolution.
- For many infections, the onset of a measurable antibody response is 5-7 days after the infection. If samples are taken before infection, the initial IgM test results may be negative. Antibody production Immunosuppressed patients may also continue to be seronegative.
