Phosphate groups are polar and allow the cell to exist in water.
Explanation:
A hypothesis is defined as an educated guess , while a research question is simplify a research wondering about the world .
Answer:
<em>The offspring which carries the allele II will be homozygous dominant.</em>
Explanation:
A dominant trait can be described as a trait which masks the effect of a recessive trait. A recessive trait can be described as a trait which gets masked by the dominant trait.
A homozygous dominant trait occurs when both the alleles for the gen are dominant. A heterozygous dominant trait occurs when one allele is dominant and the other is recessive for the trait.
Hence, a homozygous dominant trait will carry the alleles II.
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.
hope this helps :)
Warning Dont copy all of this i just answered this question to give you idea of what it is
<span>It binds itself to the receptors present on the surface of the cell membrane, which activates the enzymes present inside cell. Then It passes through the cell membrane and attaches itself to a receptor protein present in the cytoplasm.
It passes on the signal to the secondary messengers inside the cell, which activate the receptors on the cell membrane.</span>
