In certain breeds of dogs, deafness is due to a recessive allele (d) of a particular gene, and normal hearing is due to its dominant allele (D). What percentage of the offspring would be expected to have normal hearing if a normal heterozygous (Dd) dog and a deaf dog (dd) mated ?

Answer:

1.the elements

2. subscripts

3.right

4.atoms

5.one

6.brackets

7.multiplied

8.subscript

9.right

Explanation:

Answer: High temperature and drying were both associated with greater per capita mortality rate. Smaller population sizes at high temperatures and drying regimes may result from increased desiccation of adults and thus higher mortality. These precipitation effects on adult production are absent at 22°C

OR

Other than toxic metals, temperature rise and low resource availability are factors that are also known to stress populations. A rise in temperature generally accelerates metabolic rates and hence population growth rate

Answer:

A. Yes, because every child has a 50% chance of having brown eyes

Explanation:

This is the correct answer

According to the Punnett square that is given below, the argument made by Teddy may not have correct evidence. This is because it is not possible to have all 4 children in his family has brown eyes. So, the correct option for this question is B.

A Punnett square may be characterized as a type of table in which all of the plausible consequences for a genetic cross between two individuals with known genotypes are given.

According to the context of this question, the genotype of the mother is Bb which has a brown phenotype because brown eye (B) is dominant over blue eyes (b). While the genotype of the father is bb. This is blue eyes.

When both these genotypes are crossed, the genotypes of offspring are Bb, Bb, bb, and bb. This means that the individuals have both traits of blue and brown phenotypes by 50% each.

Therefore, the correct option for this question is B.

Answer:

6400 years

Explanation:

Given that;

N/No =(1/2)^t/t1/2

No = amount of radioactive material originally present

N = amount of radioactive material present at time t

t= time taken for N amount of radioactive material to remain

t1/2 = have life of the radioactive material

2.5/40 = (1/2)^t/1600

1/16 =  (1/2)^t/1600

(1/2)^4 = (1/2)^t/1600

4 = t/1600

t = 4 * 1600

t = 6400 years

B. It improves its ability to survive and reproduce.

Explanation:

Answer:

75%

Explanation:

The allele for the dominant round phenotype is represented by R while the allele for recessive wrinkled phenotype is represented by r. In this question, two heterozygous parents are crossed i.e. Rr × Rr.

These parents will produce gametes as follows: R and r. Using these gametes in a punnet square (see attached image), the following offsprings will be produced: RR, Rr, Rr and rr. The RR, Rr, Rr offsprings will have a round phenotype while the rr will have a wrinkled phenotype. This means that 3/4 × 100 = 75% of the offsprings will be round.

Answer:

A primitive whale which he named Pakicetus.

Explanation:

Philip Gingrich is a vertebrate paleontologist at the University of Michigan. He has performed extensive research on whales at the Egyptian desert of Wadi Hitan. His research team member discovered a skull whose braincase was bigger than that of a walnut. Gingerich was able to link the small-brained animal, to an early whale.

The auditory bulla had an s-shaped bony crest known as the sigmoid process and these two features helped whales to hear in water. The case, however lacked other features that helped whales hear beneath the waves. This led Gingrich to the conclusion that the unknown animal was semi-aquatic. This finding also lent credence to the possibility of whales evolving from terrestrial animals.
