DNA is in what form during interphase?
Answers
Answer:
During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
DNA is in form during interphase During interphase, the cell DNA isn't condensed and is loosely distributed.
What happens during interphase?A stain for heterochromatin (which shows the placement of chromosomes) indicates this large distribution of chromatin. The equal stain additionally indicates the organized, aligned shape of the chromosomes in the course of mitosis.
Nuclear DNA remains in a semi-condensed chromatin structure throughout the interphase. During the S phase, DNA replication results in the creation of identical pairs of DNA molecules, known as sister chromatids, which are tightly linked to the centromeric region.
During the S phase, the centrosome is duplicated.

Answer:
Stalactites form on the ceiling when water seeps through the ceiling and deposits calcite. Eventually a soda straw develops, which develops into a stalactite after many more depositions of calcite.
Stalagmites form when calcite-rich water falls to the floor from the ceiling, splattering minute amounts of calcite on the floor. After many such depositions, a stalagmite begins to take shape.
Explanation:
In general, we can say that stalactites form on the ceiling of a cave and grow towards the floor, while stalagmites form on the floor and grow towards the ceiling.
More fully, we can say that a stalactite forms when a quantity of water rich in calcite flows through the fissures of a rocky soil and infiltrates the roof of a cave where it also flows, due to the action of gravity. However, this drop of water and calcite does not fall on the cave floor and gets stuck in the ceiling. Over time, the water in this drop will evaporate, but the calcite will sediment in the shape of a ring, still attached to the cave ceiling. This process is repeated countless times, until a hollow calcite tube, called straw, is created. Over time this Straw will start to accumulate sediment and will clog. This promotes a modification of its shape, which changes from a tube to an inverted cone, with a point facing the cave floor. At that point the stalactite is formed.
Stalagmite occurs when the drop of water and calcite falls on the floor of the cave and likewise, the water in the drop will evaporate and the calcite will settle. The more drops that undergo this same process, the calcite sediments accumulate, but this time, they will not form a hollow tube, but a solid tube. This is how stalagmite is formed.
The formation of stalactites and stalagmite lasts for many years and when a stalactite meets a stalagmite, it can form a single structure, called a column.
The calcium rich water gets deposited on the roof and also get deposited on the floor of the caves. This calcite deposition form ring like structures.
The correct answer is:
Stalactites form on the roof when water flows through the roof and sediments calcite. Eventually, a soda straw forms, that grows into a stalactite after many more accumulations of calcite.Stalagmites form when calcite-rich water falls on the ground from the roof, dispersing little amount of calcite on the ground. After many such depositions, a stalagmite starts to take shape.This can be explained as:
Stalactite grows on the ceiling towards the floor while the stalagmite form on the floor and form the structure in an upwards direction.When the roof caves get infiltrated by the calcium-rich water the stalactite is formed.The calcite water gets accumulated over and over and a ring is formed.This tubular structure is called straw.When the calcite water drops on the floor of the cave then the water will evaporate leaving the calcite behind.Over time, this calcite will sediment and will form a solid structure.Therefore, this is how stalagmite and stalactite are formed.

What is the role of complementary base pairing in the replication of DNA?
A It reduces the number of errors in the process of DNA replication.
B It introduces more hydrogen bonds between the nucleotides.
C It ensures that the replicated DNA is an exact copy of the parent DNA.
D It allows the replicated DNA to have a different nucleotide arrangement
Answers
Answer:
c. it ensures that the replicated DNA is an exact copy of the parent DNA
Explanation:
This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).

Which evidence supports the theory of ocean floor spreading?
A) The rocks of the ocean floor and the continents have similar origins.
B) In the ocean floor, rocks near the mid-ocean ridge are cooler than rocks near the continents.
C) The pattern of magnetic orientation of rocks
is similar on both sides of the mid-ocean ridge
D) The density of oceanic crust is greater than the density of continental crust.
Answers
Answer:
C
Explanation:
Abundant evidence supports the major contentions of the seafloor-spreading theory. First, samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge.
The evidence supports the theory of ocean floor spreading which is the pattern of magnetic orientation of rocks and is similar on both sides of the mid-ocean ridge.
The theory of ocean floor spreading was formulated in 1960 by Harry Hess after studying different ocean floor patterns and formation.
The oceanic crust forms along submarine mountain zones involves the formation of oceanic crust along mid-ocean ridges which then later spread out to other areas. The farther the oceanic seafloor from the mid-ocean ridges , the older they are.

Answers
Answer:
The two nucleotides are located on DNA strands that are parallel to each other
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is one of the two types of nucleic acids. It is a molecule composed of a nitrogenous base, pentose sugar and a phosphate group. According to the information given in this question, Adenine is the last nucleotide at the 3' end of one strand of DNA. The following are factual about the nucleotide;
- Since DNA is a double-stranded molecule, the Adenine nucleotide will be base-paired with Thymine nucleotide (complementary base pairing) on the other DNA strand.
- Since complementary DNA strands are opposite to one another, this means that if the adenine has an unlinked 3' hydroxyl group, then the thymine must have an unlinked 5' phosphate group.
- Nucleotides in a DNA strand are joined to one another via a covalent bond called PHOSPHODIESTER BOND. Hence, the adenine and the thymine are each bonded to the previous nucleotide in the strand by a phosphodiester bond.
- In the complementary base pairing between two nucleotide bases, there are two hydrogen bonds between the adenine and thymine nitrogenous bases i.e. A=T.
- DNA strands that make up a molecule are complementary and opposite to one another, hence, they are said to be ANTIPARALLEL.
What is the difference between a haploid, diploid, and zygote?
Answers
Answer:
[tex]\color{Blue}\huge\boxed{Answer} [/tex]
Haploid" refers to any cell that has 23 chromosomes (half of the total 46). "Gametes" are specifically sex cells that have 23 chromosomes. "Diploid" refers to any cell that has all 46 chromosomes. "Zygote" is the result of two gamete (haploid) cells fusing, and becoming a diploid cell.
Haploid means n, Diploid means 2n, while zygote is the fusion of two gametes that possess a nature of 2n.
What do you mean by Gametes?A Gamete may be defined as a cell containing only one set of dissimilar chromosomes, or half the genetic material necessary to form a complete organism.
Haploid is the quality of a cell or organism having a single set of chromosomes. A Diploid is a cell or organism that has paired chromosomes, one from each parent. In the case of humans, the haploid number is equal to 23, while the diploid number is equal to 46. A zygote is the fusion of two gametes that possess a nature of 2n, which is equal to 46.
Therefore, Haploid means n, Diploid means 2n, while zygote is the fusion of two gametes that possess a nature of 2n.
