Answer: D. the mucus that helps the sperm travel to the uterus is too thick.

Artificial insemination is the technique in which the sperms are introduced into the female's cervix or uterine cavity. This results in pregnancy through in vivo fertilization. Women cervix is blocked by thick mucus which block the entry of sperms. Therefore, artificial insemination would be better in such situation than other forms of treatment.

Brrunno [24]

Solution :

Red is dominant over the white leaves and pointed is dominant over smooth.

Red = R , white = r

Pointed = P , smooth = p

Red, pointed x white,smooth ------ Parents

RRPP rrpp

RP rp ----------------- Gametes

RrPp -------- $F_1$

(red, pointed)

When this $F_1$ is test crossed,

RrPp x rrpp ---- $F_1$ test cross

Gametes → rp

RP ---------- RrPp - red, pointed - 36 parental type

Rp ---------- Rprp - red, smooth - 14 re- combination

rP ----------- rrPp - white pointed - 10 re- combination

rp ----------- rrpp - white, smooth - 40 - parental type

Total = 100

As this ratio is deviating from 1:1:1:1, it indicated the two genes are linked.

Linkage strength = percentage of crossing over = map distance between the genes.

Percentage crossing = recombination frequency = percentage of recombination.

Recombination frequency $=\frac{\text{total no. of recombination}}{\text{total no. of progeny}}\times 100$

$=\frac{14+10}{100} \times 100$

= 24 %

= 24 map units

According to the cell theory, which structure contains cells? A)blood B)water C)carbon dioxide D)chromosome

MrRa [10]

The correct answer is option A, that is, blood.

Cell theory in biology refers to the universally acknowledged scientific theory that living species are constructed of cells, that is, they are the basic fundamental and structural unit of all species, and that all the cells arises from the pre-existing cells. The theory is credited to Schwann and Schleiden. The three postulates of the theory are:

1. All living species comprises of one or more cells.

2. Cell originate from the pre-existing cells.

3. The cells is the fundamental unit of organization and composition in organisms.

fgiga [73]

Answer:

ribosome, cell membrane, nucleus

Explanation:

The organelles that perform similar functions in both plant and animal cells among the listed organelles would be the ribosome, the cell membrane, and the nucleus.

First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.

The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.
