Answer:
The Cell Wall of plants are more geometrical, than animal cells. Plant cell wall are also stronger.
Plant cell is larger than animal cells
Plant cell have chloroplast while animal cells doesn't
Explanation:
Answers:
1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.
2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.
3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.
Step-by-step explanation:
Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.
Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.
Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.
Answer: True
Explanation: A vector is used to take up foreign DNA into host cell. They are used in recombinant DNA technology (for cloning) because they replicate at a high rate, have antibiotic resistant gene and genetic markers that are used for recognition. Most commonly used vectors are E.coli and smaller circular DNA.
Generally, hurricane causes transfer of heat from the ocean to the atmosphere through evaporation. The evaporation of water from the sea surface into the atmosphere is enhanced by hurricane's surface wind, which transport the water vapours to the part of the atmosphere called troposhpere. The wind speed in an hurricane is directly related to the surface pressure of a storm, the stronger the difference in the air pressure in the ocean surface, the higher the wind speed.
<h3>ANSWER.》 A Punnett square determines all of the ways in which alleles can combine. It may be used to predict ratios of offspring genotypes and phenotypes. Punnett squares cannot determine actual outcomes.</h3>
