Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.
The answer is
B, a euglena uses a flagella in order to move. Euglena is a one celled organism
under the Kingdom Protista. A flagella (or flagellum plural) is a long strand
like structure that is located in the front end part (more like a tail in front).
It flips to the left and right in order for the organism to move. It is
connected to the reservoir, which contains the storage of food for the
organism.
Living would not be possible because without the greenhouse effect the earth would be a solid rock or ice.
I also believe it is C.
All of these organs, skin, lymph nodes, white blood cells, and spleen, act to enhance human immunity.
Answer:
1 (100%)
Explanation:
H allele is incompletely dominant to the h allele =Hh ( normal levels of blood cholesterol)
hh homozygotes having extremely high levels of blood cholesterol =hh
If Hh × hh
The F1 generation = Hh, Hh, hh, hh
The probability that their first child will have normal levels of blood cholesterol;
= 1/1
= 1 (100%)
