A cell wall is a permeable layer found in plant cells which acts as a membrane through which water molecules can pass through while animal cells do not have cell walls.. they just have a cell membrane which is selectively permeable to some chemicals or substances.. water does not move from the region of higher to lower concentration in animal cells

In short, plant cells have cell walls that allow osmosis while animal cells do not have cell walls for osmosis to take place

hope it helps you :)

Instead in our hands... something else happens rills or groove shaped lines are formed in our fingers.. it is an adaptation for our body to provide for some friction in water...

In rats, the allele for long whiskers is dominant to the allele for short whiskers. At another gene locus, a dominant allele pro

PilotLPTM [1.2K]

Answer:

25%

Explanation:

We have 2 independent genes with 2 alleles each: L/l and W/w

W_: whiskers
ww: no whiskers
L_: long whiskers
ll: short wiskers

Individuals with short whiskers will have the genotype WWll or Wwll.

A cross between a rat heterozygous for both genes and a homozygous recessive rat is done:

-The homozygous rat will produce only wl gametes.

-The heterozygous rat will produce the following gametes: WL, Wl, wL, wl.

If you do a Punnett Square, you'll get that 25% of the offspring will be WwLl and will have short whiskers.
