Photosynthetis, burning of fossil fuels, plant respiration.
Answer:
The bones of skeletal system serve to protect the body's organs and support the weight of the of the body ,giving the body it's shape
Explanation:
The muscles of the muscular system attach to these bones, pulling on them to allow for movement of the body
Photosynthesising primary producers require sunlight. Therefore, in the ocean, phytoplankton would be concentrated within the surface layers of the ocean where the sunlight penetrates. Phytoplankton support a wide range of marine life: zooplankton feed on phytoplankton, which in turn support fish and so on.
Answer:
During the S phase at interphase in meiosis I
Explanation:
During the S (DNA synthesis) phase at interphase in meiosis I, DNA replication occurs here where the chromosomes are doubled. This phase does not occur in meiosis II. At the end of meiosis II, the chromosome number becomes halved in the sex cells. The cell just goes on to divide to ensure haploidy of chromosomes in the gametes such that the sperm from the male and egg from female are both haploid. Fertilization brings about diploidy of the zygote itself
Answer:
D
Explanation:
It's false that "cells that contain mitochondria can reproduce". The function of mitochondria is to provide energy to the cell. Like prokaryotic cells do not contain mitochondria in it because it is a membrane-bound organelle. And prokaryotic cells can divide and produce new cells.
