Explanation:
Well, its extremely hot in the hydrothermal vents. Scientists simply believed it would be impossible for anything to survive due to the heat. Bacteria and micro-organisms were able to adapt to growing there, though. So in short words, they survived extreme conditions teaching scientists that life was quite adaptable.
Weird fun fact: In Switzerland it is illegal to own just one guinea pig. Felt the need to mention that ^ Sorry, I know it has nothing to do with the question but i felt it was worth speaking of.
I'm not sure what you mean by this but here is a diagram of a nephron!! Hope this helps?
Explanation:
The phenotypes and genotypes of the progeny can be determined by a dihybrid cross of the parents.
The heterozygous male will have the genotype 'SSww' and the heterozygous female will have the genotype 'ssWW'.
When crossed, the F1 offsprings will have a hybrid genotype of 'SsWw'. These offsprings are heterozygous with spotted skin and wooly hair.
On self-crossing of the F1 hybrids, we find four different combinations of the alleles- SW, Sw, SW and sw. The probability of getting each of these combinations is 1/4.
Hence, the probability of any dihybrid type is 1 out of the 16 possible genotypes. Using Punnet square, we find
9 SSWW: 3 SSww: 3 ssWW : 1 ssww
This is the phenotypic ratio of the offsprings.
The ratio of the possible genotypes will be 1:2:1:2:4:2:1:2:1.
Homeostasis is the ability to maintain constant internal conditions when outside conditions change.
For example, when temperatures in the body fall below 37° C, the nervous system signals the muscular system to
cause the body to shiver. When you shiver, your muscles move. Tiny muscles attached to hairs on the skin contract and pull the hairs up straight, forming goose bumps. This movement generates thermal energy and helps raise body
temperature. Keeping the body’s temperature constant requires that the endocrine system, the nervous system, and the muscular system work together.
It was affected by natural selection.
If this is wrong someone please tell me.
