Oxygen relights a glowing splint. What does this tell you about the chemical properties of oxygen, compared to nitrogen?

Answer:

Explanation:

A glowing splint exposed to pure oxygen will burst into flames

because the process of combustion will be greatly accelerated. The

glowing splint exists in a normal atmosphere comprised of

approximately 20% oxygen. Think of the effect of fanning over

glowing embers in order to restart a fire. You are 'pushing' more

oxygen over the embers. Exposing a glowing splint to 100% oxygen

has an even greater effect.

Two humans mate who are heterozygous for earlobe shape where attached earlobes (A) are dominant to free earlobes (a), and earwax
MariettaO [177]

Answer:

3/16

Explanation:

This question involves two different genes coding for earlobe shape and earwax quality. The alleles for attached earlobes (A) and wet earwax (E) are dominant over the alleles for free earlobes (a) and dry earwax (e).

According to this question, two humans mate who are heterozygous for both genes i.e. AaEe × AeEe. Each parent will produce the following gametes: AE, Ae, aE, ae.

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

* Attached earlobe, wet earwax (A_E_) = 9/16

* Attached earlobe, dry earwax (A_ee) = 3/16

* Free earlobe, wet earwax (aaE_) = 3/16

* Free earlobe, dry earwax (aaee) = 1/16

Hence, the probability of these parents having their first child with dry earwax (ee) and attached earlobes (A_) i.e. genotype A_ee is 3/16.

What substance, produced by virus-infected cells, diffuses to neighboring cells to help them fight a viral infection
Ksenya-84 [330]

Interferons:  

The body releases glycoproteins as the defensive response to virus are called interferons.

The interferons initiate the series of molecular changes and elicit the immune cells to fight the pathogens or foreign particles. These interferons affect the growth of cells and inflammation. Interferons are the cytokines and are responsible for intercellular signalling. The interferons does not directly affect the multiplication of virus instead, it does not let other cells allow virus to use its machinery and replicate. Interferons are of three types: alpha, beta and gamma. The gamma interferon is majorly responsible for the immune response.
