Answer: option "A" One seed develops from each ovule.
Explanation:
Ovules are the female reproductive part of the plant which is internally covered by the nucellus and integuments further helped in fertilization and development of seed.
After fertilization, ovule is the part of the plant develops into seed, after a period of time food tissue is developed inside it consisting the seed coats called integuments.
pollen grains or sperms are being transferred through the pollen tube to the embryo sacs from integuments only, which results into the fertilization and development of seed.
Answer:
No
Explanation:
The nucleus is where cells store their DNA, which is the genetic material, Right? Well, Prokaryotic cells do not have a nucleus. So, therefore (lol) they do not have genetic material.
Your welcome, Love.
Upwelling is a process in which cold water from depths arise to the surface,
it's important because :
- It bring a lot of nutrients to the surface of the ocean
- It maintain the temperature of the ocean
hope this helps
True! because without gravity the spacecraft wouldn't go where there wanted it, in the time that they wanted it
Answer:
The statement that is correct is that all cells have the same genes, but different genes are active in different cells.
Explanation:
Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.
Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.
All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. <u>There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation</u>.
The other choices are wrong because:
- <em>The eyes look different from the liver, because they have the same genes, but only some are expressed.
</em>
- <em>Differentiated cells and tissues do not lose their genes.
</em>
- <em>All cells have DNA.</em>
