Are the cells in this image prokaryotic or eukaryotic?

Human embryonic development is the development and formation of the human embryo. It is characterized by the process of cell div

iragen [17]

The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.

The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:

Zygote: Fertilized ovum.
Blastocyst: Cluster of cells that is the result of the zygote going through cell division.
Embryo: Unborn human that is still developing, usually before the 8th week of gestation.
Fetus: Unborn human in development after the 8th week of gestation.

Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

In corn, small pollen (sp) is recessive to normal pollen (sp+) and banded necrotic tissue, called zebra necrotic (zn), s ssive t

alex41 [277]

Answer:

Option B

Explanation:

Please see the attached image

Given -

Allele for small pollen is "sp"

Allele for normal pollen is "sp+"

and "sp+" is dominant over "sp"

Allele for zebra necrotic tissue is "zn"

Allele for normal necrotic tissue is "zn+"

and "zn+" is dominant over "zn"

Cross is carried out between

sp+ sp zn+ zn x sp+ sp zn+ zn

The gametes of the parent cells are -

sp+ zn+, sp+zn, spzn+, spzn

The cross would be as follows

sp+ zn+ sp+zn spzn+ spzn

sp+ zn+ sp+ sp+ zn+ zn+sp+ sp+ zn+ znsp+ sp zn+ zn+ sp+ spzn+ zn

sp+zn sp+ sp+ zn+ znsp+ sp+ zn znsp+ sp zn+ zn sp+ sp zn zn

spzn+ sp+ sp zn+ zn+sp+ sp zn+ znsp sp zn+ zn+ sp sp zn+ zn

spzn sp+ sp zn+ zn sp+ sp zn zn sp sp zn+ zn sp sp zn zn

Hence, option B is correct

The molecular basis of the Gram stain is the amount of _______ in the bacterial cell wall. bacteriophage spirochete peptidoglyca

Anna11 [10]

<h3><u>Answer;</u></h3>

peptidoglycan

The molecular basis of the Gram stain is the amount of<u> peptidoglycan</u> in the bacterial cell wall.

<h3><u>Explanation</u>;</h3>

Gram stain is differential stain that is very useful for identifying and classifying bacteria as either gram negative or gram positive.
Gram negative are those that decolorize easily, such as E. coli, while Gram positive are those that retain the primary stain and do not decolorize easily.
The result depends on the bacteria cell wall structure, the cell wall of a Gram-negative bacterium is composed of 20 percent or less of peptidoglycan.

How are meiosis and<br> mitosis different?

goldenfox [79]

Answer:

Mitosis provides two diploids (2n) somatic cells that are genetically indistinguishable from each other and the primary parent cell, whereas meiosis creates four haploids (n) gametes that are genetically individual from each other and the original parent (germ) cell.
