Answer:

Bryophyta. (Ans. B)

Explanation:

Bryophytes are consisting 3 division of embryophytes (non vascular land plants) which are; mosses, liverworts, and hornworts. They prefer to live in moist places, and can live to drier places also. Bryophytes reproduce with the help of spores, and they do not produce seeds, and flowers.

Bryophytes are gametes dominant in nature, it means they are longer lived, prominent plant is the haploid gametophyte. The sporophytes diploid become visible only occasionally, and nutritionally depends and attached to the gametophytes.

During a routine prenatal care visit, a pregnant woman in her last trimester of pregnancy reports that she has occasional shortn
Gala2k [10]
Shortness of breath is very common in the last trimester of pregnancy. This is because, the baby inside the uterus is growing and it starts to push the uterus that compresses the lungs above the diaphragm. This, leads to restricted expansion of the lungs while breathing and causes shortness of breath. Another reason for shortness of breath can be due to low iron content in the body.
If a pregnant woman in her last trimester reports occasional shortness of breath, the nurse should instruct her to:
1. take deep breath and start doing prenatal yoga
2. sleep on the left hand side
3. practicing good posture and standing straight
4. relax as much as possible

List the three laws of Newton in your words. Give an example of each.
OLga [1]

1. For every action there is an equal and opposite reaction

2. Force = mass times acceleration

3. An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted on by another force.

3. One example is a rock rolling down a hill. You could use a stick or your foot to stop it, but otherwise it would keep rolling

2. An example for law No.2 is pushing a shopping cart. If you push an empty shopping cart, it will go faster than a full shopping cart because the full shopping cart has more mass.

1. One example is a cup on a table. The cup exerts a force down on the table due to gravity, the table exerts an equal and opposite force on the cup to stop it falling through the table

How do plants transport these micronutrients to the reproductive tissues (tissue)?
Trava [24]
What about transport you might ask well

in plants, how does a Redwood, one of the tallest trees in the world, move water from the soil to the needles on its tallest branches over 300 ft in the air? (That’s over 30 stories high!) Or how does a carrot transport the sugars made in its green, leafy tops below the surface of the soil to grow a sweet, orange taproot? Well, certain types of plants (vascular plants) have a system for transporting water, minerals, and nutrients (food!) throughout their bodies; it’s called the vascular system. Think of it as the plant’s plumbing, which is made up of cells that are stacked on top of one another to form long tubes from the tip of the root to the top of the plant. To learn more about it, let’s study the stem.

Beginning with a cell that just fertilized ( 1 cell ) how many times must it divide to become a 64 cell blastomere ?
natka813 [3]

A cell that just fertilized has to divide 6 times to form a 64 cell blastomere.

<u>Explanation:</u>

Human reproduction begins with the fusion of male gamete sperm and female gamete ovum. The fusion of sperm and ovum forms the zygote that is diploid. The zygote then undergoes mitotic division to develop into embryo.  

The zygote first divides into two and the two individual cells divide again to form four individual cells and so on. Thus the number of cells after each division can be represented by the equation 2^n  where n is the number of divisions.  in the question it is given that the blastomere has 64 cells.

2^n=64  

n=6

This means that the fertilized cell has to divide 6 times to develop into 64-celled blastomere.
