Answer:

The reintroduction of the wolf nearly 25 years ago to the country's first national park has brought change: Overpopulated elk herds have thinned, allowing some willow and aspen groves to return and thereby creating better habitat for songbirds and beavers.

Suppose two brown haired parents have a red haired child what are the genotypes of each parent? And what % for them to have red

Savatey [412]

1) B- brown; b- red hair

Having brown hair is a dominant trait while red hair is recessive.
If the parents had a red-haired child it means they were carriers of the red hair trait, so their genotype is Bb

2)Getting their genotypes together would result in the possibilities that you see at the image below.
1/4 = 25% BB - brown
2/4 = 50% Bb brown but carrier
1/4 = 25% bb red hair
Answer: 25%

3) The genotype of the child, as i said before would be bb. By having both alleles being recessive the child will show red-hair. If it was any other genotype( BB or Bb), the child would have brown hair, like their parents.

Suppose virus A has a viral genome of 19,000 bp, and 10,000,000,000 viruses are replicated in an infected individual in a single

Kitty [74]

Answer:

1 day.

Explanation:

From the given information:

The rate of mutation induced by RNA polymerase is:

$\implies \dfrac{1}{10000}= 0.0001$

Since the genome comprise of 19000 bp;

To complete a single replication, the viral cycle induce: $= \dfrac{19000}{1000}$

$= 1.9 \ mutation \\ \\ \simeq 2 \ mutation$

However, in a single day; 10,000,000,000 viruses are reported to be replicated.

Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

$= \dfrac{10,000,000,000}{2} \\ \\ = \text{5000000000 \ mutations \ in \ a \ half \ day which is half} \\ \\ \text{ the given no of the replicated virus}$

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.

individuals from which of the following backgrounds are least likely to experience emerging adulthood? group of answer choices w

Verizon [17]

Emerging adulthood is predominantly found in developed countries mainly in western cultures. There most young people completing tertiary education, marrying and becoming parents at a median age of about 30.

Adulthood, the period of human lifespan in which people reach full physical and mental maturity. Adulthood is generally considered to begin when he is 20 or he is 21. From around 40 years old to middle age, around 60 years old to reach the old age.

"Emerging adulthood" is a term that describes the stage of development from about 18 to 29 years old, experienced by most people in their 20s in Westernized cultures and perhaps other parts of the world as well.

Growing adults share five traits: self-focus, instability, identity-seeking, in-between, and a sense of possibility. Emerging adulthood occurs in all ethnic, cultural, and socioeconomic groups, but the experience of emerging adulthood varies among groups.
