Need HELP ASAP please bt tonight if someone could answer this

Peptide hormones a. are able to pass through the membrane and bind to a receptor in the cytoplasm. b. bind to a receptor in the

ozzi

Answer:

The correct answer is option B. It bind to a receptor in the plasma membrane.

Explanation:

Hormones can be aminoacid based hormones (peptide or amine) or the steroid base hormones on the basis of their nature. Amino acid based proteins are molecules that are proteins,

Peptide hormones are the protein or peptide molecule that release in blood by the exocytosis in the form of preprohormones that mature later and bind to the receptor present on the surface of the plasma membrane of the target cell. The binding of the peptide hormone to the receptors a secondary messenger shows up in the cytoplasm.

Thus, the correct answer is option B. It binds to a receptor in the plasma membrane.

In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke

lara31 [8.8K]

Answer:

Explanation:

As given,

Allele A for blue anthocynin.

aa for yellow kernel;

at second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are: AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

a)

Recombinant progeny are 169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.

The means for transmission of disease-causing microorganism is provided by the ____.

Sergio039 [100]

Answer: The means for transmission of disease-causing microorganism is provided by the direct or indirect contact.

Microorganisms can cause disease only once they are transferred to the body. The disease causing microorganisms are termed as pathogens which are transmitted by several ways such as from skin to skin, by nuclei droplets, through blood and body fluids or via air. In vector transmissions the disease is carried by the parasitic insects via animals, air borne transmission occurs when microorganisms move through air or the dust particles, droplet transmission occurs by coughing, sneezing or talking by the person who is infected while indirect transmission occurs by physical contact or by touching contaminated objects.

Which of the following will allow for the greatest reduction in an individual’s carbon footprint?

goldfiish [28.3K]

The carbon footprint can be decreased by a great amount if the incandescent bulbs are replaced with the compact fluorescent bulbs. The compact fluorescent bulbs uses approximately seventy five percent less energy than the incandescent bulbs as they do not use heating mechanism to light. This leads to less emission of the green house gases and thereby reducing the carbon footprint.

Hence, the correct answer is 'option a - replacing incandescent bulbs with compact fluorescent bulbs'.
