Telomerase Indicate whether each of the following statements about telomerase is true or false. 1. With each cell division, chromosomes gradually shorten in the absence of telomerase activity. TrueFalse 2. During embryonic and childhood development in humans, telomerase activity is relatively low compared to the level of activity in most somatic cells of an adult. TrueFalse 3. Cells that divide frequently tend to have relatively low levels of telomerase. TrueFalse 4. The activity of telomerase in most mature somatic cells is kept high by increasing the expression of the gene encoding this enzyme. TrueFalse 5. Mice with low telomerase activity appear to be normal for up to six generations, but they show steadily decreasing telomere length that eventually leads to nonviable offspring. TrueFalse 6. When telomerase is added to cells grown in culture, their lifespan decreases relative to controls that have no telomerase added. TrueFalse 7. Cancer cells generally have high levels of telomerase activity, which allows them to divide indefinitely without the chromosomes getting shorter and shorter. TrueFalse

Does The hydrogen bomb rely on the process of nuclear fission.

Answers

Answer:

The hydrogen bomb is a mixture of fission and fusion reaction.

Explanation:

The atomic bomb contains either uranium or plutonium and rely on fission, a nuclear chain reaction that splits a nucleus or atom into two parts. To make a hydrogen bomb, uranium and plutonium would still be required, along with two additional hydrogen isotopes called deuterium and tritium.

The hydrogen bomb is a mixture of fission and fusion reaction. and it can be 1000 times stronger than any atomic bomb

What evidence in a slice of bread showed the presence of gas?

Answers

Every slice of the bread, contains a number of blister like pores. These blister like pores suggests that the air or some gas might be present there. In case, the bread has no air, the surface of the bread must be smooth rather than rough.

The bread is formed by the fermentation of the sugar molecules present in the dough with the help of yeast. These blisters like structure on the bread is present due to the gas produced during fermentation.

The _______ the time period during which a species lived and the _______ the distribution of its fossils, the better an index fossil the species is. shorter; narrower shorter; wider longer; narrower longer; wider

Answers

The index fossils have a shorter time period and wider geographical distribution of fossils.

What is an Index fossils?

An Index fossils refers to class of fossils that had a wide geographical distribution and they were present for a comparatively shorter period of time.

They helped in the construction of geological periods that are commonly used today.

Thus, the index fossils have a shorter time period and wider geographical distribution of fossils.

Therefore. the Option B is correct.
