Answer:
<h2>3/16</h2>
Explanation:
As given;
Brown coat color (B) is dominant over (b), so B is dominant over b.
Solid color (S) is dominant over the spotted(s), so S is dominant over s.
crossing between true breeding brown, solid colored guinea pig( BBSS) with red spotted pig( bbss)
so parents are BBSS× bbss
gametes are, of parent-1; BS, and parent-2: bs
F1 is : BbSs,
cross between F1 and F1
F2 is : BBSS, BBSs, BbSS, BbSs............BBss..........Bbss........bbSS.......bbss etc
So red and solid color offspring are (bbS_) = 3/16
First of all, we need to find out how much money is needed ,
25 x $ 135 = $ 3375
Next, we just need to divide this amount to total contributors
$ 3375 / 45 = $ 75 per person
Hope this helps
Answer:
"As a molecule moves through the plasma membrane it passes through <em>a hydrophilic layer of phospholipid heads then a hydrophobic layer of phospholipid tails and then another hydrophilic layer of phospholipid heads".</em>
Explanation:
Biological membranes are formed by two lipidic layers, proteins, and glucans.
Lipids characterize for being amphipathic molecules, which means that they have both a hydrophilic portion and a hydrophobic portion at the same time. These molecules have a lipidic head that corresponds to a negatively charged phosphate group, which is the polar and hydrophilic portion. They also have two lipidic tails that correspond to the hydrocarbon chains -the apolar and hydrophobic portion- of the fatty acids that esterify glycerol.
Membrane lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.
Through this lipidic bilayer, some molecules can move from one side of the cell to the other, which happens because of concentration differences. When this occurs, molecules must pass through the hydrophilic layer of phospholipid heads then through the hydrophobic layer of phospholipid tails and then again through another hydrophilic layer of phospholipid heads.
<u>Population</u> is the term that defines groups of individuals that belong to the same species and live in the same area
Explanation:
In an ecological system, when a group of species of living organisms group and live in a particular locality area, it is referred to the population of that species.
Within an ecological boundary, there can be more than one type of population living in an area and all these different types of the population are interdependent with each other.
Within a population of a species, the individuals of the species interbreed, reproduce, grow and survive among themselves.
