Check which type(s) of stem cells the characteristics apply to.

Answer:

Oogenesis in the female is the process that produces fertile eggs, ready for fertilisation by the male sperm. Each egg has only one of each of the 23 human chromosomes - normal body cells have a pair of each, having 46 chromosomes in total.

To produce egg cells, the process of oogenesis takes place in the female ovary. Progenitor cells divide through a cell division process called meoisis, which is also known as a reduction division.

Instead of one cell splitting into two identical cells, four cells are produced which have half the normal number of chromosomes - they are described as being haploid.

The four cells are all genetically different because the process of meiosis involves cross overs of the chromosomes during division, so mixing up the genes inherited from the woman's mother and the woman's father. This variation produces fitter offspring as it widens the genetic variation that is possible.Explanation:

Nitrogen is a limiting plant nutrient because the bulk of the available nitrogen in the atmosphere is not usable by plants.

Plants are not able to make use of the nitrogen in the atmosphere directly. Atmospheric nitrogen needs to be converted into usable forms before it can be accessed by plants.

The conversion of atmospheric nitrogen to usable form by plants is known as nitrogen fixation and this is achievable by the activities of certain bacteria.

Answer:

The receptor protein that is embedded in the cellular membrane must accept the signal.

Explanation:

When it receives the signal this protein will then go through a conformational change. This will change the shape and how it interacts with the molecules around it. Different receptor protein will act in different ways.

Answer:

As their name implies, GPCRs interact with G proteins in the plasma membrane. When an external signaling molecule binds to a GPCR, it causes a conformational change in the GPCR. This change then triggers the interaction between the GPCR and a nearby G protein.

What happens to the membrane protein (gray) when it is activated by the signal molecules?

The membrane protein interacts with the nearby GPCR.

Mutations that occur in gametes:

A. May be passed on to future generations

-Correct mutation in gametes(sex cells) can be passed onto future generation.

B. Can be important in the evolution of a species

-Yes, it can lead to different phenotype that may be important to evolution of a species.

C. Affect the functioning of the gene in which they occur

->it can affect the functioning of the gene, but it can be silent mutation or mutation in intron

D. All of these are correct.

Because they have a wide surface area to speed up absorption, root hair cells are designed to absorb water and mineral ions.

Plants are anchored by root hairs that emerge from the surface of the soil and take up water and minerals.

Vascular tissue in the heart of the root transports food produced in the leaves to the root, while transporting water and minerals away from it.

Its main purposes include anchoring the plant, absorbing water and dissolved minerals and transferring them to the stem, as well as storing reserve food.

Water and nutrients are mostly taken up by root hairs from the rhizosphere.

Therefore, root hair cell have large surface area that enable the cell to carry out its function.

The types of waves that emanate from and earthquake are the body waves (P-waves and S-waves), and the surface waves. The surface waves travel along the suface, and are are the slowest, even though they do the most damage in an earthquake. While the P-waves travel the fastest through solids, liquids, and gases. S-waves, however only travel through solids.

Answer:

Cell cycle consists of interphase and mitosis. During interphase there are 3 phases- G1, S and G2 phases. G1 is the resting phase after previous mitotic phase, S phase is DNA synthesis phase and G2 phase is again resting phase.

DNA synthesis occurs before mitotic phase which is the actual cell division phase and chromosomes are condensed during mitotic phase therefore it's in the chromatin form that DNA is synthesised.
