Lamarck's theory cannot account for all the observations made about life on Earth. For instance, his theory implies that all organisms would gradually become complex, and simple organisms disappear.

Lamarck’s theory of evolution, also called as theory of inheritance of acquired characters was rejected since he suggested that the acquired character which an organisms gain through its life experiences are transferred to its next generation, which is not possible since acquired characters does not bring any change to an individual’s set of genes.

During DNA replication each stands of dna is used as a temple to produce a complementary stand of DNA this process is shown belo
castortr0y [4]
<h2><u>Full question:</u></h2>

During DNA replication, each strand of DNA is used as a template to produce

a complementary strand of DNA. This process is shown below. Which base

will attach to location 2?

A. Adenine B. Allimene C. Thymine D. Tyrosine

<h2><u>Answer:</u></h2>

Base thymine will get attached the location 2.

Option C

<h3><u>Explanation:</u></h3>

DNA replication is the process by which the genetic material that is deoxyribonucleic acid is getting replicated into its daughter DNA by the process which involves a lot of enzymes and energy. This process involves the formation of complementary base pairing between the nitrogen bases present in the nucleotides of DNA.

As the DNA replication starts the enzymes helicase and gyrase comes in action which open up the double stranded DNA which then is acted by DNA dependent DNA polymerase which gets attached to the coding strand of the DNA and starts accumulating the nucleotides from the cytoplasm and nucleoplasm that are complementary to the nitrogen base that is present on the coding strand. This process is very fast and can go up to speed of 30 to 40 base per second. This process is fully based on the complementary base pairing nature of DNA which bring the nucleotide from the nucleoplasm that is complementary to the base present on the coding strand. And this nucleotide is the same that is present on the other strand of the DNA because the DNA double helix contains the the complementary bases that actually forms hydrogen bond between themselves.

Here in the location to we can see that adenine is present as the nitrogen base. The complementary base to adenine is thymine. So the complementary base that will be present there will be thymine itself

Why does an octopus or squid use its tentacles?
spin [16.1K]
Octopus and squid have little suction cups on their tentacles. It helps with sticking onto food (so it doesn't get away) and also helps with sticking into things. If it wanted to camouflage into some rocks, it can use its tentacles to cling to to the rock.

Tentacles can also grab and carry things. Scientists have made tests where they would put a clam in a jar with the lid screwed on. The octopus would grab onto the jar and use its tentacles to twist the lid off.

Without tentacles, octopuses and squids would be pretty helpless and probably couldn't survive in the deep ocean.

IrinaK [193]

Nucleus can be defined as a large organelle found in the Eukaryotic cells and it is also  know as the cell's command center,thus it controls the activity of the cells

Explanation:

  • The answer to the above question is (c )nucleus. During the cell cycle the nucleus of the cell mediates the replication of the of the DNA and controls the gene expression.
  • The nucleus contains a structure which is known as nucleolus and which is made up of protein and ribonucleic acid(RNA)
