PLEASE HELP!! I HAVEN'T A CLUE ON THIS

Biology

Explanation:

All linear chromosomes the newly synthesized strands of DNA are shorter at the 5' prime and then that same region of the parental strands. There is a 3’ overhang at one end of the daughter strand strand;mboth resulting daughter DNA strands 3' overhangs. Without any other cellular process these overhangs are typically digested by nucleases. However this would lead to the shortening of daughters DNAs with each replication of parental DNA.

To combat this chromosomes in eukaryotes contain regions called telomeres. These have repetitive non-coding sequences which function to protect important genes from deletion during cell division and DNA shortening during the process of DNA replication.

The human genome contains about 3 billion base pairs. During the first cell division after fertilization of a human embryo, S ph
Nataly [62]

Answer:

5556

Explanation:

If a DNA polymerase synthesizes in average 50 nucleotides/second, that means that in three hours (10800 seconds) it synthesizes about 540000 nucleotides.

However, if the human genome is composed of 3000000000 (3 billion) base pairs (nucleotids), the minimum number of DNA polymerases (working in the same number of origins of replication) to finish the duplication of all the genome in three hours is 5555,5. (3000000000/540000). As we know there is no half polymerase, so we round to 5556.

5556 molecules of DNA polymerases acting on 5556  origins of replication are needed.

What most likely happens when lithospheric plates move apart deep below the ocean?
Alisiya [41]

Magma seeps up along plate boundaries and forms mountains.

Factor 1 creates competition and factor 2 creates genetic variation.

Explanation:

Question 1: Magma seeps up along plate boundaries and forms mountains.

When lithospheric plates move apart they create divergent plate margin where magma seeps up along the plate boundary and forms series of mountains. The mid oceanic ridge was formed this way.

  • The lithosphere lies on the weak and molten asthenosphere.
  • Different plate interactions produces a wide range of plate movement.
  • Along a divergent margin usually, two oceanic plates are forced to move apart.
  • The forces the asthenosphere to rise through seeps as magmatic bodies.
  • The rising magma them crystallizes along the margins of the plate to form mountain chains like the mid-oceanic ridge.
  • It is common to find young rocks at the plate margin and the older ones away from spreading centers.

Question 2: Factor 1 creates competition and factor 2 creates genetic variation.

Scarcity of space leads to competition between organisms and availability of mates creates genetic variations.

  • In an ecosystem with limited space, there will pressure on available resources.
  • This will lead to different organism developing strategies to efficiently adapt to their environment.
  • Organisms will in turn begin to compete with one another for the limited resources.

When we have a diverse number of mating options, genetic variation occurs. This suggests that we can have different gene combination as a result of the mating organisms.

A variation in the genetic pool of a place leads to better adaptable traits to survive the environment.

Weigh is a measure of pull of gravity on an object true or false
user100 [1]

Answer:

The answer is "TRUE!"

Explanation:

Weight is a source of forceful motion that is generated by the pull of gravity. Gravity that is originated in the center of the earth, attracts smaller objects towards that center, in which the measurement of how strong that force really is, is weight.
