The babies will all have brown eyes because a homozygous dominant vs. homozygous recessive will always result in the dominant trait showing. The parents genotypes have to be BB for the male and bb for the female because homozygous means the letters will match for genotype so male has to have BB, and the female shows the recessive trait so she has to have bb. The only genotype the babies can have is Bb because the parents each only have a B and a b to give respectively so that's all they can do. This means the babies will have the brown eyed trait and a heterozygous genotype.

Snezhnost [94]
I would say either the first, second, or fourth answer; waves have a very strong impact on the movement of sand and other particles under the water. Erosion of particles off an island are similar in this case.
It wouldn't be anything about a tropical storm; it's no where in the question and we don't know how many storms Florida has or how strong they are.

kolbaska11 [484]

Answer:

Option 1, a charged end and a noncharged end

Explanation:

Complete question

If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____

  1.  a charged end and a noncharged end
  2.  three fatty acid molecules, all pointing in different directions
  3.  two fatty acid molecules pointing in different directions
  4.  both a saturated fatty acid and an unsaturated fatty acid
  5.  two charged ends

Solution

The structure of phospholipids consists of the following groups and molecules –  

a) A glycerol molecule  

b) Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature

c) Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.  

When the phospholipids are placed in  water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.

Hence, option 1 is correct

Which goes where ? Mitosis Vs. Meiosis
nika2105 [10]

Answer:

Mitosis, Meiosis, and both are written below

Explanation:

Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas

  • This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.

Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages

  • This is because meiosis occurs in gametes and is used in reproduction.

Both: Chromosomes need to replicate before the whole process begins, a form of reproduction

  • This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.

When parallel light rays exit a concave lens, the light rays diverge. converge. come together. remain parallel.
Temka [501]

When parallel light rays exit a concave lens the light rays diverge. Option A. This is further explained below.

<h3>What is ray divergence?</h3>

Generally, ray divergence is simply defined as when light rays begin at a point and diverge,

In conclusion, when light rays begin at a point and spread, it is called ray divergence.
