Answer:

Deterministic super-resolution: The most commonly used emitters in biological microscopy, fluorophores, show a nonlinear response to excitation, and this nonlinear response can be exploited to enhance resolution, such as STED, GSD, RESOLFT and SSIM.

Stochastic super-resolution: The chemical complexity of many molecular light sources gives them a complex temporal behavior, which can be used to make several close-by fluorophores emit light at separate times and thereby become resolvable in time, such as Super-resolution optical fluctuation imaging (SOFI) and all single-molecule localization methods (SMLM) such as SPDM, SPDMphymod, PALM, FPALM, STORM and dSTORM.

Identify the parts of the female and male reproductive system and their functions.

Lena [83]

Female:

*Ovaries - release of oocytes (eggs), estrogen and progesterone.

*Oviducts (fallopian tubes) - where fertilization of the oocyte occurs to form a zygote.

*Uterus - where the zygote develops

*Cervix and vagina - allow for the entry of sperm for fertilization

Male:

*Testes - Releases testosterone and sperm

*Vas deferens - Passageway for sperm

*Epididymis - allows the sperm to pass from the testes and vas deferens and equips them with semen so they can survive internal fertilization

*Penis - releases sperm into the external environment for fertilization to occur

Serhud [2]

Color blindness is X linked trait and is carried on X chromosome so when a A mother with normal color vision and a color blind father have a color blind daughter the offspring will be
. Some of their sons can have normal color vision
because male is XY and female XX
so i conclude option B is correct

In the rat, the allele for red eye colour is dominant over the alleles for brown colour. Consider a cross between a rat that is

chubhunter [2.5K]

Answer:

1) RR x rr

2) Shown below

3) 100% Rr with red eyes

4) Punnett square shown (Rr x Rr)

5) 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)

Explanation:

Let's say the allele for red eyes is R and the allele for brown eyes is r.

1. A cross between a h0m0zygous dominant (two copies of the dominant allele, R) and h0m0zygous recessive (two copies of the recessive allele, r) is: RR x rr

2. R R

r Rr Rr

The F1 generation is shown in the Punnett square above.

3. The F1 generation are 100% Rr. They are heterozygous. Since red (R) is dominant, the rats all have red eyes

4. A cross between the F1 generation (Rr x Rr) gives the F2 generation

R r

R RR Rr

r Rr rr

5. 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
