Answer:
25% of the offsprings will be BBCC
Explanation:
This is a typical dihybrid cross involving two distinct genes. One coding for fur colour and the other for claw sharpness. The allele for brown fur (B) is dominant over the allele for black fur (b) in the first gene while the allele for sharp claws (C) is dominant over the allele for dull claws (c) in the second gene.
In a cross between parents with genotypes: BbCc x BBCC , each parent will produce four possible allelic combinations of gametes as follows:
BbCc: BC, Bc, bC, bc
BBCC: BC, BC, BC, BC
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced with four distinct genotypes:
BBCC (4)
BBCc (4)
BbCC (4)
BbCc (4)
According to the question, an offspring that is homozygous dominant for both traits will possess a genotype: BBCC
N.B: Homozygous dominant means contains same alleles for the dominant trait.
Hence, offsprings with genotype, BBCC, from this cross are expected to be 4 out of the 16 possible offsprings. Hence, the percentage is 4/16 × 100 = 25%.
Answer:
The answer is - CERCLA established a trust fund to finance both cleanup and enforcement actions. This fund is sometimes called the Superfund.
Explanation:
CERCLA is Comprehensive Environmental Response Compensation and Liability Act and it can also be called the Superfund. This act was passed in 1980 due to the intolerable hazardous waste practices and management that were ongoing in the 1970s. The goal of the CERCLA is to protect human health and the environment by preventing environmental contamination and ensuring the cleanup when it occurs.
Answer:
The anterior lobe makes up about 80% of the pituitary gland. It regulates growth, metabolism, and reproduction through the hormones that it produces.
Explanation:
The production of these hormones is either stimulated or inhibited by chemical messages sent from the hypothalamus to the pituitary.
I found this radiography online, i hope it's the same:
1- <span>Spinous process
2- Atlas ( it's the first vertebra)
3- Axis </span><span>( it's the second vertebra)
4- Transverse process
5- </span><span><span>Intervertebral disc</span> (present between vertebras)
6- body of the vertebra
the occipital bone is a reference that it's the posterior side, while the mandibule indicates it's anterior.
