The pollen grain is actually the male gametophyte generation of seed plants. Inside the anther, pollen mother cells divide by meiosis to form pollen grains whose nuclei contain half the number of chromosomes characteristic of the parent plant.

Answer:
Gabriel's horn
Explanation:
What the question is asking for is a 3-dimensional shape that has a lot of surface area and only a little volume. The first thing I thought of was a geometric figure called Gabriel's Horn. A quick search on Wikipedia will explain better than I can, but basically it has infinite surface area but finite volume. You probably couldn't test the shape in any experiment, though, since it's only theoretical and can't exist in real life.
Let me know if I can explain anything in a clearer way!
Answer:
- spiders
they break down organic material that then provide nutrients for the entire food web.
- freshwater shrimps
Animals like shrimp and crabs can break the materials down to detritus. Then bacteria reduce the detritus to nutrients.
-moss
Moss is considered both a producer and a decomposer because it produces its own food through photosynthesis and helps to break down organic matter into nutrients. ... In the forest, moss carpets the floor and fallen organic matter such as rotting logs. The moss helps to decompose the logs and recycle the nutrients.

Answer:
C.) 26 - 13
Explanation:
During mitosis, DNA is replicated during the S phase so that when the cell divides the daughter cells will have the same number of chromosomes that the parent cell had.
DNA replication also occurs during meiosis, but the cell divides twice, so the daughter cells will have half the number of chromosomes that the parent cell had. This is because the daughter cells are sex cells, which combine with another sex cell (either an egg or a sperm) to form one cell with a combined chromosome number.
Carbon has four electrons in its outer shell, thus it can form four bonds
