When blood glucose levels decrease, in between meals, during fasting or from starvation, increased levels of ________ help to in
JulijaS [17]

Answer:

B. Glucagon

Explanation:

Glucagon is a pancreatic hormone, secreted by the alpha cells of islets of Langerhans. Whenever the blood glucose level falls, glucagon is released to increase the blood glucose levels. This function of glucagon is quite opposite to the function of insulin and hence both are antagonistic hormones. Insulin reduces the blood glucose where as glucagon increases the blood glucose.

Glucoagon is large polypeptide of 29 amino acids. Since it helps in increasing the blood glucose homeostatic levels it is called as hyperglycemic hormone. It does so by stimulating certain processes such as:

- Stimulating Glycogenolysis i.e breakdown of glycogen to release more glucose from liver.  

- Stimulating Gluconeogenesis i.e. synthesis of glucose from non-carbohydrate sources like proteins.

- Glucagon inhibits the process of glycogenesis i.e. synthesis of glycogen, the storage form of glucose.

Select all that apply.
andriy [413]

The <em>correct</em> answer is:

Penicillium

Aspergillus

The lesson states:

If you've ever heard of or taken penicillin to fight off an infection, you can thank a member of the imperfect fungi called penicillium. Some mold species of penicillium are also important in the flavoring and aging of cheese. Roquefort and Camembert cheese owe their distinctive flavors to these fungi. Aspergillus is an imperfect fungus that is found on decaying food. It also contributes to the production of organic acids like citric acid. <u>Both penicillium and aspergillus produce enzymes that are purified and used in various industrial compounds and in medicine.</u>

Suppose a population is carrying a condition controlled by two alleles: R (dominant) and r (recessive). Only homozygous individu
White raven [17]

<span><u>The answer is A. 72.25 percent.</u>

The Hardy-Weinberg principle can be used:</span>

<em>p² + 2pq + q² = 1</em> and <em>p + q = 1</em>

where <em>p</em> and <em>q</em> are the frequencies of the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq </em>are the frequencies of the genotypes.

<span>The <em>r</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15

To calculate the <em>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85

Knowing the frequency of the <em>R</em> allele (<em>p</em>), it is easy to determine the frequency of the RR genotype (p²):
p² = 0.85² = 0.7225

Expressed in percentage, p² = 72.25%.</span>

1. A student is completing a Punnett square for a trait (X/x) that is autosomal and inherited by the dominant allele. The father
zvonat [6]

Answer:

C

Explanation:

autsomsal means that it is not x-linked/ realted to gametes. Dominate means that it needs only one X to get the trait

Using the punnet square

             X       x

      x     Xx   xx

      x     Xx   xx

there is 2 X which means there is a 50% change that their child will get the trait

Triss [41]

The answer is: the source of information could be biased

The scientist is interviewing environmentalists and then generalized their opinion as "people". An environmentalist is a person that cares about the environment, so they will more likely to deny the option that harms the environment. If the dam harmful to the environment, most environmentalists will not approve it.
