What is the point of DNA replication
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell
Explanation:
DNA replication is the biological process in which two identical copies of DNA are produced from one original DNA molecule.
The steps involved in the process of DNA replication are as follows:
The first step in DNA replication is to ‘unzip’ the double-helix structure of the DNA molecule.
This is carried out by an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G).
The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.
One of the strands is oriented in the 3’ to 5’ direction (towards the replication fork), this is the leading strand. The other strand is oriented in the 5’ to 3’ direction (away from the replication fork), this is the lagging strand. As a result of their different orientations, the two strands are replicated differently.
A short piece of RNA called a primer (produced by an enzyme called primase) comes along and binds to the end of the leading strand. The primer acts as the starting point for DNA synthesis. DNA polymerase binds to the leading strand and then ‘walks’ along it, adding new complementary nucleotide bases (A, C, G and T) to the strand of DNA in the 5’ to 3’ direction. This replication is continuous. Numerous RNA primers are made by the primase enzyme and bind at various points along the lagging strand.
Chunks of DNA, called Okazaki fragments, are then added to the lagging strand also in the 5’ to 3’ direction. This type of replication is called discontinuous as the Okazaki fragments are joined up later.
Once all of the bases are matched (A with T, C with G) an enzyme called exonuclease strips away the primer(s).
The new strand is proofread to make sure there are no mistakes in the new DNA sequence.
Finally, an enzyme called DNA ligase seals up the sequence of DNA into two continuous double strands.
The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.
Following replication, the new DNA automatically winds up into a double helix
(b) DNA replication occurs in S phase of cell cycle in eukaryotes. If cell division is not followed after DNA replication then the replicated chromosomes (DNA) would not be distributed to daughter nuclei. A repeated replication of DNA without any cell division results in the accumulation of DNA inside the cell nucleus, leading to polyploidy.

What does the phrase, “When it pours, the desert stores” refer to?
The phrase “When it pours, the desert stores” refers that deserts have underground water reserves, so when it rains the desert stores water.
Is there water in the Sahara Desert?Recently, a large amount of groundwater was identified in North Africa in the Sahara desert region, but at high depths that make it difficult for the poor population of the region to exploit it.
With this information, we can conclude that the phrase “When it pours, the desert stores” refers that deserts have underground water reserves, so when it rains the desert stores water.

The phrase refers to the water-storage abilities of desert plant species.
Adaptation for water storageDesert plants such as cactus are well-adapted to store water for long-term usage when water is available.
This ability makes desert species to be able to withstand drought. The reserved water is utilized when water availability reduces or ceases totally.
Thus, when it rains, the desert species store water.

Explain why birds are more closely related to bats than butterflies even though they are able to fly
Answer:
bird's and bats have Bones inside their wings and butterflies don't...so that's why they aren't related
While bats and birds only have one pair of wings, insects have two pairs. While bat and bird wings have bones, insect wings don't.
How birds are more closely related to bats?Bird wings have feathers, butterfly wings have scales, and bat wings have exposed flesh. All of these creatures have developed wings as a result of their adaptation to living in the air.
The relationship between birds and bats is based on their behaviors rather than their ancestry. Even though bats and birds are not even remotely related, they both independently developed the capacity to fly.
Bats are mammals, just like people, only bats are true fliers among mammals, they fly by flapping their wings. Some mammals exclusively glide, like flying squirrels.
Therefore, bats and birds only have one pair of wings, while insects have two pairs.

Which part of a plant begins the reproductive process to allow the plant to spread and grow new plants? (1 point)
O stems
O leaves
O flowers
O Roots
Answer:
The answer would be the flowers
Explanation:
The flowers have pollen in or on them that bees, wasps, and butterflies pick up while drinking nectar. The pollen is eggs and is spread from flower to flower.
Flowers is a part of plant to begins the reproductive process to allow the plant to spread and grow new plants.
What is flower?Pollination, the act of sexual reproduction in flowering plants, is how it happens. Stamens, the male sex organ, and pistils, the female sex organ, are found in flowers.
The portion of the stamen that carries pollen is called the anther. The male gametes are found in pollen. For reproduction to occur, pollen must be transferred to the stigma, a region of the pistil.
When a plant's own pollen nourishes its own ovules, self-pollination occurs. When animals or the wind carry pollen from one plant to another, cross-pollination occurs.
Cross-pollination has the benefit of preserving a species' genetic diversity. When environmental conditions change and organisms must adapt, genetic variety is useful. Some plant characteristics really work to stop self-pollination.
Therefore, Flowers is a part of plant to begins the reproductive process to allow the plant to spread and grow new plants.
