The rabbit population shown in the graph could have increased less in the third year than in the previous two years due to habitat loss through urban sprawl.

In ecology, habitat loss refers to the loss of the habitats of living organisms. The loss could be due to natural disasters or anthropological activities.

When the population of organisms of a particular species experiences habitat loss, it automatically results in a loss to some parts of the population.

In other words, habitat loss causes a decline in the population of organisms.

In the graph, the rabbit population experienced almost equal growth in the first and second years. The growth experienced in the third year, however, is not as big as in the first two years.

The reduction in the growth of the population could be linked to different factors. The logical one from the options is habitat loss through urban sprawl.

The statement (A) is correct about rRNA that it helps mRNA move along the ribosome.

Ribosomal ribonucleic acid is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells. rRNA is a ribozyme which carries out protein synthesis in ribosomes.

Moreover, rRNAs are found in the ribosomes and account for 80% of the total RNA present in the cell. Ribosomes are composed of a large subunit called the 50S and a small subunit called the 30S, each of which is made up of its own specific rRNA molecules.

Therefore, ribosomal RNA (rRNA), molecule in cells that forms part of the protein-synthesizing organelle known as a ribosome and that is exported to the cytoplasm to help translate the information in messenger RNA (mRNA) into protein.

Cytoplasm aids in the movement of organelles and supports organelles in a gel-like fluid explains the role of cytoplasm in maintaining homeostasis for the cell.

The cytoplasm is the portion of a cell that lies between the nuclear membrane and the plasma membrane. It includes cytoskeleton and organelles in cytosol. Numerous cellular organelles reside in the cytoplasm of cells. Cytoplasm is a semifluid substance of the cell.so, as a result cytoplasm helps in movement of the organelles inside the cell.

The term "homeostasis" refers to the interior environment's preservation of almost constant circumstances. Every cell inside an organism is engaged in the ongoing struggle to maintain homeostasis. All  cells including cell organelles , tissues and organs including cell membrane perform functions to maintain relatively constant conditions i .e Homeostasis.

If I were to look at the sample of the unknown cells under a microscope, I would be able to determine if the cells came from a plant or an animal by checking if the cells have a cell wall or not.

A cell is the smallest unit of life that is able to remain functional and live independently. A cell consists of a cytoplasm surrounded by a membrane. The cytoplasm contains various organelles that support life such as the nucleus, mitochondria and Golgi apparatus.

If one were to view a sample of unknown cells under a microscope, the best way to determine where it came from is to check if it has a cell wall or not. Cells with a cell wall are plant cells, and cells without a cell wall are animal cells.

The cell wall is a rigid structure found outside the cell membrane that provides additional chemical and mechanical protection for the cell. Animal cells have no cell walls, hence, are more flexible and take various shapes if viewed under a microscope.

Extraneous variables can threaten the internal validity of your study by providing alternative explanations for your results. In an experiment, you manipulate an independent variable to study its effects on a dependent variable.

When extraneous variables are uncontrolled, it’s hard to determine the exact effects of the independent variable on the dependent variable, because the effects of extraneous variables may mask them.

Controlling extraneous variables is an important aspect of experimental design. When you control an extraneous variable, you turn it into a control variable. Uncontrolled extraneous variables can also make it seem as though there is a true effect of the independent variable in an experiment when there’s actually none.

DNA replication is semi-conservative and involves different enzymes in charge of unwinding the DNA molecule (topoisomerase), separating strands (helicase), creating primers (Primase), and adding complementary nucleotides (Polymerase). 1) DNA polymerase, 2) Topoisomerase, 3) Okazaki fragment, 4) DNA helicase, 5) RNA primase.

DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.

DNA Replication consists of the unwinding and opening of the double-stranded DNA molecule and producing two new molecules using these original strands.

DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one.

Initiation phase

Helicase and topoisomerase are the first enzymes involved.

Elongation phase

DNA polymerase, primase, and ligase act in this phase.

These enzymes are responsible for DNA elongation. They add nucleotides to the growing chain, from 3' to 5' extremes. The new chain grows in 5’-3’ direction.

DNA strands are antiparallel, and replication occurs only in 5'-3'direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.

The replication process results in two DNA molecules, each of them carrying an old strand and a new strand.

The correct answer [c] Consuming alcohol lowers inhibitions.

Consuming alcohol lowers the inhibitions.

In psychology, inhibition is the conscious or unconscious restraint or restriction of a process or behavior, particularly of urges or wants. The ability to inhibit oneself from acting on some impulses, such as the desire to hit someone in a fit of rage, and the ability to postpone the enjoyment of enjoyable activities, all serve important social functions. Conscious inhibition occurs frequently in daily life and appears whenever two opposing urges are felt (e.g., the desire to eat a rich dessert versus the desire to lose weight).

According to psychoanalytic theory, inhibition serves as a mediator between the superego (the conscience) and the id (primitive desires). Taboos are socially imposed inhibitions that are raised to the level of prohibition, such as those against incest or murder of unwritten laws

Example: When you get the cold, your body inspects it. It realizes it hasn't seen that germ before, and responds by making special proteins to fight off the cold. This process isn't fast enough to stop the common cold, but it is fast enough to make you get well again.

Scenario: Next year, you get a vaccine for the stomach flu. You notice the doctor says to you that it injects the same germ into you. You ask why, and she responds that, "If we put this dead germ into you, then your body will recognize it. Just like it did when you got it last year. It will ahead of time make proteins to fight off the stomach flu. It will remember it forever." So when the stomach flu tries to sneak into your immune system, your body will already know how to fight it off-because the vaccine showed the body what the virus was, and what it was made of.

Apply: It's like a job interview. The vaccine is the person, presenting what they are and what they are capable of. The body is the boss, taking note of this. They will hire you--just like how the body lets it in. And turns out this job isn't for you. Similar to how the body will figure out the virus is foreign and bad. The boss will then know that people similar to you, wont work in this job field. Just like the body will make proteins and remember that that virus is bad.
