What do you need help with regarding them

Answer:

a punnett square shows the probability that the parents off spring will have a certain phenotype be cross the parents two genotypes

further Explanation:

so a punnett square take two parents and crosses them to calculate the chance you will get a certain phenotype by drawing a square and splitting it into four quarter you take the dads two genotypes and put them on the top of the square and you put the moms on the side now that you have the parents genotypes labeled you cross them the letters are there alleles so if you have a upper case allele then it is dominant meaning the offspring get the dominant trait (phenotype) now if you have two lower case letters then the offspring get the non-dominant trait (phenotype) so Bb is gets a dominant trait  BB is a dominant trait but bb is a non dominant trait the way you cross them is say you have BBxbb here's what the chart will look like

    B    B

b   Bb  Bb

b   Bb  Bb

i hoped this helped if it di please give me brainlest

Can a protein that is not part of the cell membrane diffuse through the membrane? If not, why?
Katyanochek1 [597]

Answer:

Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane. Although ions and most polar molecules cannot diffuse across a lipid bilayer, many such molecules (such as glucose) are able to cross cell membranes. ... Channel proteins form open pores through the membrane, allowing the free passage of any molecule of the appropriate size.t is the proteins, therefore, that give each type of membrane in the cell its ... Many extend through the lipid bilayer, with part of their mass on either side ..... Many hydrophobic membrane proteins can be solubilized and then purified in an active, if not entirely ..... Many Membrane Proteins Diffuse in the Plane of the Membrane.

In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
Dvinal [7]

Answer:

Phenotype genotype Number of individuals

Red RR 245

Pink Rr 210

White rr 45

Number of alleles in total

R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency

r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency

Predict (Hardy Weinberg) genotype frequencies=

p^2 + 2pq + q^2 = 1

p= 0.7

q=0.3

0.49 + 0.42 + 0.9 =1

According Punnett Squares in F1 we have=

Rr* rr = Rr 50% and rr 50%
