Explain how a compound microscope allows you to see magnified images.
Answer:
The classic compound microscope magnifies in two steps : first with an objective lens that produces an enlarged image of the object in a "real" image plane. This real image is then magnified by the ocular lens or eyepiece to produce the virtual image. Two convex lenses can form a microscope.
Explanation:
Answer:
it has multiple magnifying glasses in the scope.
Explanation:
A compound light microscope uses two lenses at the same time to view objects-the objective lens, which gathers light and magnifies the image of the object, and the ocular lens, which one looks through and which further magnifies the image. ... it also allows light to pass to the ocular lens.

Intro
Answer:Peptide Bond and Water
Explanation:
The two amino acids animated above are joined together by a peptide bonds.
What do you mean by peptide bond?Along a peptide or protein chain, a peptide bond is an amide-type covalent chemical bond that connects two consecutive alpha-amino acids from C1 of one alpha-amino acid to N2 of another.
A covalent bond between two amino acids is known as a peptide bond. Peptide bonds are used by living things to make long chains of amino acids called proteins. Proteins play a variety of roles, including providing structural support, catalyzing crucial reactions.
When the carboxyl group of one molecule reacts with the amino group of the other molecule, a molecule of water H20 is released, forming a peptide bond between the two molecules.

Tanisha says that the Moon looks dark from Earth when the Moon is in two different places: always when it is closest to the sun, as in Top View #1, and always when it is furthest from the sun, as in Top View #2. Is Tanisha correct? If she is correct, explain why the Moon always looks dark from Earth in both of these positions. If she is incorrect, explain when the Moon looks dark from Earth and how the light on the Moon should look in each of Tanisha’s diagrams.
Tanisha is wrong in her conclusion ( i.e. the moon will appear dark only when it is behind the earth ( furthest away from the sun ) )
The moon gets its light from the sun and the closer the moon is to the sun the more light it gets and is has to be positioned in-between the sun and the earth to have such light rays as well.
When the moon is furthest from the sun it will be positioned behind the sun ( i.e. the earth is in-between the sun and the moon ). during this period the moon will appear dark because the Earth been bigger than the moon sheds away light rays coming from the sun towards the moon.
Hence we can conclude that Tanisha is wrong in her conclusion.

Albinism is a recessive genetic condition in which a person lacks pigment that gives color to the skin. If the allele for albinism is represented as "a," and the functional allele is represented as "A," what will be the genotype of a person with albinism?
Answer:
The correct answer would be - "aa".
Explanation:
Albinism is an autosomal recessive genetic condition which means it will be expressed only if both alleles for the pigmentation are recessive. If a single copy of the dominant allele present with the recessive allele the expression of the recessive allele would be masked by it and skin will be pigmented however they will act as carriers of the condition.
There would be three condition or three allele combination:
AA - no recessive allele so no albinism
Aa - dominant allele with recessive allele which means carrier but pigmented skin
aa - both alleles are recessive so the albinism will be expressed.
Predict which temperature 20 degrees Celsius, 39 degree Celsius, 50 degree Celsius you would expect a human to function best. Plan a simple investigation to test your hypothesis
Answer:
39 degree Celsius
Explanation:
Human body functions well at 36 degree Celsius. All the body functions and the enzymes secretion and processes works best on the temperature 36 degree Celsius.
The enzyme of humans will function good on temperature 39 as it is the very near to the body temperature of the human. The optimal temperature would be between temperature 35 to 40 degrees for most of the enzymes.
Testing hypothesis :
Add amylase which is an enzyme present in the saliva to a concentration sugar, which acts as the reactant in a small container having a lid. Use a thermometer to mark the changes in the temperature. We have to take two identical samples of our experiment. Place one sample at a room temperature of 25 degree Celsius and the other to be heated to 40 degree Celsius. Now we have to check the concentration of the product for each temperature. And while checking the sample which is heated, we see that at some point, the rate where the substrate is being converted in to product decreases as the enzyme denaturation and the reaction will stop. The optimal temperature is the one where the product is produced at the maximum rate.

It drops as you go higher.
It is usually higher on summer days.
Its low and high are usually shown on weather map.
Which weather component is Jade describing?
Air temperature
Humidity
Precipitation
Wind speed
Answer:
Air temperature
Explanation:
Air temperature is being described by Jade according the properties highlighted.
The degree of hotness or coldness of a body is known as its temperature.
As you go higher it becomes cooler. The surface causes the warming of the air around. With height, the surface is distant from the body of air. On summer days, air temperature is higher due to more insolation. Weather maps gives a good description of air temperature from places to places.[tex]\mathrm {Hey, there!}[/tex]

C diagram best illustrates metaphase.
What is mitosis and its stages?Prophase, metaphase, anaphase, and telophase are the four stages of mitosis.
1) Prophase: chromatin forms chromosomes, the nuclear envelope breaks down, and chromosomal centromeres bind to spindle fibers.
2) Metaphase: the chromosomes align on the metaphase plate (center of the cell)
3) Anaphase: sister chromatids are drawn to opposing poles of the cell;
4) Telophase: nuclear envelope recovers, chromosomes unroll into chromatin, and cytokinesis can begin.
hence A shows anaphase, B shows prophase and D shows telophase and cytokinesis
