Cell<span> differentiation is how generic embryonic </span>cells become specialized cells<span>. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a </span>cell<span> functions

Answer:
Diffusion rate increases
Explanation:
The rate of diffusion would increase as a steep concentration gradient is maintained so more nutrients/ glucose diffuses quickly. This is also how the small intestines are adapted to have efficient diffusion rates as there are many capillary networks that allow lots of blood flow, increasing diffusion rates.
Explanation:The tetrahedral shape is formed by the electrons repulsing one another, which forms the tetrahedron—the shape in which all the electrons are as far away from one another as possible.
Examples include methane (CH4) and ammonium(NH4+).
Methane has a central carbon atom ringed by four hydrogens, which form the "spokes" of the tetrahedral molecule.
Tetrahedral molecules are nonpolar if the four surrounding atoms are the same, in the cases of methane and ammonium, and have a bond angle of 109.5˚.
However, tetrahedral molecules can also be polar if they are like chloroform (CHCl3). The central atom has four electron domains, but they are differently sized.
<h3><u>Answer;</u></h3>
q = 80 percent
<h3><u>Explanation;</u></h3>
If a trait has two alleles, p and q, and p is 20% then we can find the percent of q.
According to the Hardy-Weinberg equilibrium;
p+q = 1
Therefore;
q = 1 - p
but; p = 20% or 0.2
Thus; q = 1 - 0.2
= 0.8
The percent of q is 80%
