Scanning electron microscope is better than light microscope to study photosynthesis in algae.

The light microscope is an instrument for visualizing great detail of an object. It does this by way of developing a magnified image via the use of a sequence of glass lenses, which first attention a beam of light onto or via an object, and convex lenses to increase the picture fashioned.

Light microscopy is used to make small structures and samples seen by way of supplying a magnified photo of the way they interact with visible light, e.g., their absorption, reflection and scattering.

Lenses form the picture goal lens  gathers light from the specimen eyepiece  transmits and magnifies the photo from the goal lens for your eye nosepiece  rotating mount that holds many objective lenses tube  holds the eyepiece on the proper distance from the goal lens and blocks out stray light.

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.

1) DNA polymerase

2) Topoisomerase

3) Okazaki fragment

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.

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

An ecosystem is made up of all living things and their physical environment (or ecological system). These biotic and abiotic components are linked through nutrition cycles and energy exchanges. Photosynthesis takes place. Animals are essential for the movement of matter and energy because they eat both plants and other animals for nourishment. They have an effect on the biomass levels of both plants and microbes.

Cancer is brought on by changes (genetic changes) to the DNA of cells. A cell's DNA is organized into numerous distinct genes, each of which carries a set of instructions directing the cell's performance of specific tasks as well as its growth and division.

As a result of local tumor invasion, abnormal tumor vasculature, or tumor regression, bleeding may be brought on by the cancer itself. It might also be connected to previous chemotherapy or radiation therapy for cancer.

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.

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.
