Which statements correctly describe mutations in gametes and mutations in somatic cells?
ASHA 777 [7]

A mutation is a rare, accidental or induced modification of genetic information (DNA or RNA sequence) in the genome.


The consequences of a mutation vary according to the part of the genome affected. A mutation is said to be hereditary if the mutated genetic sequence is passed on to the next generation.

In multicellular animals, germline mutations can be transmitted to offspring, whereas somatic mutations do.


Somatic mutations do not affect cells intended for reproduction, so they are never hereditary:

* Post-zygotic mutations are the mutations that appear in the egg after fertilization. They are rarer and are expressed as mosaic in the individual concerned (the mutation will be present only in the daughter cells originating from the mutated embryonic cell).

* Mutations can appear throughout life on the DNA of any cell; they are then transmitted to the line of the daughter cells. These can, in some cases, become tumor cells and then form cancer.

A few years after a devastating forest fire, pioneer trees become established. after another 50 years, those trees are replaced
Keith_Richards [23]
Abiotic factors composed of water, light, temperature and air etc. due to fire's this primary succession was completely destroyed. Their remaining organic bodies were decomposed in soil texture.

In order to establish secondary succession there is need of water and light, because water help in translocation of food and nutrients in plants while light is important for photosynthesis.

Photosynthesis need three major components. these are H₂O, CO₂ and light, all these components are abiotic part of ecosystem. However, when secondary succession occurs, then light play a key role in changing the composition of plant community. The best example is the difference in height of plants of different community.

How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?
slamgirl [31]

Answer:

The “recommended temperature limit” indicates limit of the temperature that is good for our world and above this limit causes adverse affect.

Explanation:

The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature..

Answer:

A lunar eclipse can only occur when there is a full moon.

Explanation:

A lunar eclipse occurs when the Moon, Earth and Sun are aligned on a straight line. This alignment completely blocks the sunlight and moon is under the shadow of Earth. In this phase, moon often look red because of reflection of infrared radiations. This happens only where there is a full moon.

It is not possible to occur moon eclipse in any phase because if sunlight would reach the moon surface directly, it is not a moon eclipse Further, lunar eclipse can last upto a few hours because the shadow of Earth is greater because of its size compared to the moon's size and it takes a while until moon is completely out of that shadow. Lastly, a lunar eclipse doesn't create an eerie color in the sky rather a red color due to infrared radiations.
