The brain is encased within the cranium, which is the large, superior part of the skull.

The bone covering known as the cranium contains the brain. The skull shields the brain from harm. The skull is the collective name for the bones that guard the face and the cranium. There are 22 bones in the skull. All of the skull's other bones, excluding the mandible, are fused together. The skull's bones can be split into two primary groups:

  • Cranial bones (8 bones)
  • Facial skeletal bones (14 bones).

The 8 bones that form the cranium are one ethmoid, one frontal, one occipital, two parietal, one sphenoid, and two temporal.

aev [14]
The protein involved in elongation of Bacillus Antrasis to form its typical shape is called FtsZ.
FtsZ is a GTpase that polymerises in nucleotide dependent manner head to tail to form a single stranded filaments that assemble into a contractible ring.

lana [24]

Answer:

a) 1/2 red, 1/2 pink; b) all pink; c) 1/4 red, 1/2 pink, 1/4 white; d) 1/2 white, 1/2 pink

Explanation:

The flower color trait in snapdragons shows incomplete dominance: the heterozygous genotype produces an intermediate phenotype between the two different homozygous genoytpes.

<u>The possible genotypes and phenotypes are:</u>

  • R1R1 : red
  • R1R2: pink
  • R2R2: white

<h3>a. R1R1 X R1R2 </h3>

The R1R1 individual only produces R1 gametes. The R1R2 parent produces 1/2 R1 gametes and 1/2 R2 gametes.

<u>For that reason, the F1 will be:</u>

  • 1/2 R1R1 (red)
  • 1/2 R1R2 (pink)

<h3>b. R1R1 X R2R2 </h3>

The R1R1 individual only produces R1 gametes. The R2R2 parent only produces R2 gametes.

<u>For that reason, the F1 will be</u> :

  • 100% R1R2 (pink)

<h3>c. R1R2 X R1R2 </h3>

Both parents are heterozygous. This is a monohybrid cross, and from Mendel's Laws <u>we expect the following offspring:</u>

  • 1/4 R1R1 (red)
  • 2/4 R1R2 (pink)
  • 1/4 R2R2 (white)
<h3 /><h3>d. R1R2 X R2R2</h3>

The R1R2 parent produces 1/2 R1 gametes and 1/2 R2 gametes. The R2R2 individual only produces R2 gametes.

<u>For that reason, the F1 will be:</u>

  • 1/2 R2R2 (white)
  • 1/2 R1R2 (pink)
