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.

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.

1. Why ATP is an expendable molecule of energy?
2. Write the initial components, end product, where phosphorylation happens. Are there enzymes in the steps? Mention at least two enzymes.
Answer:
1. The reason there is energy released in the process is because the products formed (ADP and hydrogenphosphate/phosphate) have stronger covalent bonds (plus intermolecular forces with the surrounding solution and dissolved ions) than the starting materials.
2. The end product of oxidative phosphorylation is ATP and water. ATP synthesis is coupled with the transfer of electrons to O2, which combines with protons to form water. Phosphorylation is the chemical addition of a phosphoryl group (PO3-) to an organic molecule. The removal of a phosphoryl group is called dephosphorylation. Both phosphorylation and dephosphorylation are carried out by enzymes (there are enzymes involved). kinases and phosphatases, From the family of Enzymes.

What is the difference between habituation from a neural perspective?
The difference between habituation from a neural perspective is that habituation refers to the fading of the response over the course of monotonous stimulation, and sensitization refers to processes of increased response.
What is the habituation process?Habituation is an example of non-associative learning in which there is an automatic decrease in the intensity of a response to a repetitive, weak stimulus, without serious consequences, which allows, for example, ignoring stimuli such as noise, the ticking of a clock, etc.
With this information, we can conclude that the difference between habituation from a neural perspective is that habituation refers to the fading of the response over the course of monotonous stimulation, and sensitization refers to processes of increased response.

What is an invasive species?
Answer:
An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.
Explanation:
Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.
Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
