The main reason that the spores of disease-causing bacteria are dangerous is that they are very difficult to destroy. If the bacteria is not suited in the condition state of the environmental, other kinds transform to an inactive state. They advance with a hard outer covering and look out for the suitable environmental conditions. This lie dormant bacterium is known as spores. Spores are more difficult to destroy than those bacteria that are active for they have a harder outer covering.

the allele for white fur is revessive and the allele for normal fur is dominant the frequency for the normal fur allele is 0.60.

Mariulka [41]

Answer:

$36$ % of wolves have normal fur.

Explanation:

Given , the allele for white fur is recessive and the allele for normal fur is dominant

Let "N" represents the allele for normal fur and "n" represents the fur for white fur.

As per Hardy Weinberg's principle, the frequency for dominant allele is represented by "p"

Given ,

$p = 0.60\\$

Then frequency for dominant genotype will be " $p^2$ "

So, Frequency for wolves with normal fur is

$p^{2} \\0.60^2\\0.36$

Percentage of the wolves with normal fur is

$0.36*100\\= 36$ %

Filip, aged 64, was recently diagnosed with Alzheimer's. His medical reports will most likely reveal a diminished production of

UNO [17]

Answer:

Filip's medical report, diagnosed with Alzhaimer's, may reveal a diminished production of acethylcholine.

Explanation:

Alzhaimer's disease is a neurodegenerative condition that causes immediate memory loss, behavioral changes and cognitive impairment, due to neuronal alterations and atrophy.

The neurotransmitter acetylcholine —related to neuronal transmission and body movement— may experience a decrease in its production leading to Alzheimer's, according to the cholinergic hypothesis.

Many therapies and treatments at present are based on the use of drugs to correct the acetylcholine deficit.

Regarding other options:

Dopamine: alteration or deficit is related to Parkinson's disease.
Gamma aminobutyric acid (GABA): deficiency is not common and is related to a type of congenital and infantile neuropathy.
Serotonin: deficit of this neurotransmitter can lead to depression and psychological disorders.
