The complete question is as follows:
1. What does a surface area/volume ratio of 6:1 mean for the cell’s ability to get the materials it needs that move across its surface?
2. What does a surface area/volume ratio of 3:1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6:1?
Answer:
1 . Surface area to volume ratio = 3 : 1
surface area= 3 cm³ or (l = 1 cm) (1 cm x 1 cm x 3) (W = 3)
volume= 1 cm³ (1cm x 1cm x 1cm)
2. Surface area to volume ratio = 6 : 1
surface area= 6 cm³ or (1 cm x 1 cm x 6 ) (w= 6)
volume= 1 cm³
Diffusion increases with the increase in surface area to volume ratio through the semi-permeable membrane of the cell membrane that allows substances to move into the cytoplasm
Answer:
Pollution.
It become reservoir for waste deposition.
Habitat of bacteria growth.
Organisms in them die due to lack of food resources.
It's lead to algal bloom.
Explanation:
Lentic environment is a stationary or still water, i.e water that doesn't flow but it is stationary at one place. Examples are ponds, ditches, reservoirs, lakes , pool, seep.
The major challenges of lentic environment are;
It become reservoir for waste deposition.
Habitat of bacteria growth.
Organisms in them die due to lack of food resources.
It's lead to algal bloom.
It is believed that this happens because some signals that regulate development are the same between different species and because <span>they share ancient genes. </span>These ancient genes are expressed during a middle "phylotypic stage" of embryonic development for all species.
For example, human and animal embryos go through very similar stages of early development and share similar features such as tails and gill-like structures. The major difference appears to be how long it takes to reach each of these same stages.
Answer:
Two Cells
Explanation:
Budding or fission are not part of mitosis or meiosis but these are types of asexual reproduction .During budding in Yeast a small out growth appears on one side of cell , enlarges and separates .During fission one cell divides in two equal cells as in Amoeba .
As one moves through a sensory system from receptors to thalamic nuclei, to primary sensory cortex, to secondary cortex, ..... Represents the thalamic relay between the inferior colliculi and the auditory cortex.
