Answer:

Shining visible radiation from a torch beam onto a hand lights the hand up because the hand has been exposed to light.

Exposing objects to beams of radiation is called<u> irradiation</u>. The term applies to all types of radiation, including radiation from the nuclei of atoms.

Irradiation from radioactive decay can damage living cells. This can be put to good use as well as being a hazard.

Contamination occurs if an object has a radioactive material introduced into it. An apple exposed to the radiation from cobalt-60 is irradiated, but an apple with cobalt-60 injected into it is contaminated.

As with irradiation, contamination can be very useful as well as being potentially harmful.

ivolga24 [154]

Out of the following given choices;

a) The amount of oxygen produced

b) The rate of ATP synthesis by ATP synthase in the chloroplast

c) The rate at which NADPH is produced

d) The rate at which the protons are transported into the thylakoid

The answer is; A

The photosystem captures energy from sunlight and uses it to split a water molecule.   After splitting the water molecule (by taking an electron), the protein complex transports the electron to plastoquinone. The splitting of water molecules results in evolving of oxygen molecules. The hydrogen is what is used to reduce carbon dioxide to glucose.

sineoko [7]
The answer is cohesion. The high surface tension helps the paper clip (with much higher density) float on water. The property of a liquid that allows it to resist an external force, due to cohesive nature of its molecules. Cohesion refers to the attraction of molecules for molecules of the same kind. Water molecules have strong cohesive forces due to their ability to form hydrogen bond with each other.

zmey [24]
Fires in grasslands prevent the growth of shrubs. Plants can survive in these fires because most of them have parts underground, where fire cannot reach. Animals and runners aren't affected by this, because they can leave.

lys-0071 [83]

Answer:

from the image:

1. eight

2. four

3. less than

Explanation:

from the data given...

n= 4

where n= # of genes

&, the extreme # of segments=   (\frac{1}{4} )^{n}

Genes, which make up a genotype are instructions for encoding a phenotype, expressed as proteins in translation.

...one gene may have 2 alleles

An allele is an alternate form of a particular gene. Genes can have multiple alleles, but in this case...

∴4 genes= 4 × 2=<u> </u><u>8 segments</u>

<u />

<u>Thus, each allele gives </u> \frac{8}{8} = <u>1 segment</u>

<u></u>

<u></u>
