Answer:
<h2>
A) Protection of the zygote from the drying effects of air was important.</h2>
Explanation:
Diploid germ cells divide by meiosis to create haploid gametes, like sperm or egg.
Haploid gametes contain half genetic material as compared to the parent cell. Male and female gametophytes release sperm and eggs respectively. When an egg is fertilized by sperm, it becomes a diploid zygote.
Zygote matures into a sporophyte on the gametophyte plant. There is very important of protection of zygote from damage, so Protection of the zygote from the drying effects of air was important.
<u>Answer:</u>
Option (3)
The arms mostly contains old blue and blue-white stars
<u>Explanation:</u>
Spiral arms are the regions in stars extending from the middle of spiral galaxies and the barred spiral. Those long, thin areas look like a spiral and therefore give their name to spiral galaxies.
Spiral arms, though, include many young, blue stars, that render their arms so bright (due to the high mass density and the fast stellar forming rates).
1.) D- phloem is Bi-directional and can flow upward or downward
2.) C- it transports the water from the roots to the stems and leaves
3.) A- capillary action <span>is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity, so it can flow upward through the tissue
4.) B- It conducts the sugar and other metabolic materials downward from the leaves
5.) A- </span><span>The roots </span>have a type of cell called a root hair cell - these project out from the root into the soil. The water<span> absorbed by the root hair cells passes through the plant in xylem tubes, and eventually reaches the </span>leaves<span>.
6.) A- It transports </span> water<span> from roots to shoot and leaves, but it also transports some </span>nutrients. It is Uni-directional though and can only flow upward.
Hope this helps! Good luck
