what describes the relationship between DNA, genes, and chromosomes
Answer:
DNA ( deoxyribonucleic acid) is a chemical substance which is called as the genetic material of all living organisms. It is packaged into the threadlike structure, called as chromosomes. This means that chromosomes are composed of a chemical substance, which is called as DNA.
Whereas, genes are the segment of DNA ( which code for specific proteins) present on the chromosomes. Thus, they carry information for specific trait of the individual ( like eye color)
In summary, their composition and functions are similar as all play a significant role in passing information from one generation to next and thus, determine the characteristics of the offspring.
Answer:
DNA carries instructions for making the proteins a cell needs.
DNA molecules are found in chromosomes.
Genes are segments of DNA that contain instructions that code for proteins.

why are only two phenotypes possible?
Answer:
The phenotype is the physical manifestation of an organism's allellic combination (genotype). For the pea plants, if the red allele is dominant and the white allele is recessive, only two phenotypes are possible. ... Often, organisms will carry a dominant and a recessive allele of a gene.

What is the utilized equipment for studying fluorescence-labelled cells? What are the advantages of labelling the cells?
Answer:
Fluorescent labeling of cells helps in ensuring more visibility of the properties of the cell.
The equipment used in studying fluorescence-labelled cells include epi-fluorescence microscope which helps in providing a more dimensional view of the cells. The spectrophotometers is also used to determine the chemical properties of the cells through the intensity of light measured with this equipment. The flow cytometer is also used in this process of study of fluorescent labeled cells.

Examples of homozygous recessive?
Answer:
Please mark as brainliest....thanks!!!
Explanation:
An organism can be homozygous dominant if it carries two copies of the same dominant allele, or homozygous recessive if it carries two copies of the same recessive allele. Heterozygous means that an organism has two different alleles of a gene.
A homozygous recessive allele combination contains two recessive alleles and expresses the recessive phenotype. For example, the gene for seed shape in pea plants exists in two forms, one form (or allele) for round seed shape (R) and the other for wrinkled seed shape (r)

Label the type of igneous rock that will form at point A. ____
°Extrusive
° Intrusive
°Lava
°Magma
Label the type of igneous rock that will form at point B. _____
°Extrusive
°Intrusive
°Lava
°Magma
Answer:
Point A - Intrusive igneous rock
Point B - Extrusive igneous rock
Explanation:
Intrusive igneous rocks are rocks which is formed by molten magma that cools and solidifies below and within the surface of the earth, thereby forming large crystals beneath the earth surface. Examples of Instrusive igneous rocks gabbro, granite, peridotite etc.
Intrusive Ignoeus rock is formed at point A in the diagram given above.
Extrusive Ignoeus rock, on the other hand, is the opposite of Intrusive igneous rock. Extrusive igneous rock is formed when molten rocks, called magma, erupts from beneath the earth and cools and solidifies on the surface of the earth, thereby forming small crystallized rocks. Examples of extrusive igneous rocks are basalt, pumice, etc.
Extrusive Ignoeus rocks would formed at point B in the diagram above.

What happens in the first part of Interphase?
Answer:
Interphase is the part of the cell cycle that is not observable by naked eyes. During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A common misconception is that interphase is the first stage of mitosis, but since mitosis is the division of the nucleus, prophase is actually the first stage. In interphase, the cell gets itself ready for mitosis or meiosis.

Answer the questions based on the information given.
The Amur plate, a small plate, has moved away from the Eurasian plate. It has moved125,000 meters in 25 million
years. It is moving eastward.
What is the rate of motion of the Amur plate? Express your answer in
year mm
Where would the plate be after 1 million years? Express your answer in m.
What geologic feature will form between the Amur and Eurasian plates?
What is the rate of motion of the Amur plate? Express your answer in .
✔ 5 mm/year
Where would the plate be after 1 million years? Express your answer in m.
✔ 5,000 meters east
What geologic feature will form between the Amur and Eurasian plates?
✔ new ocean floor
The answers are:
Rate of motion is 5 mm/yearThe plate would be 5,000 meters east An ocean floor would form between the Amur and Eurasian plates.The rate of motion is in mm per year so you need to convert the distance it has moved to millimeters.
1 meter = 1,000 meters
125,000 will therefore be:
= 125,000 * 1,000
= 125,000,000 millimeters
Rate of motion = 125,000,000 / 25,000,000 years
= 5 mm/year
The plate is moving east and in 1 million years it would be:
= 1,000,000 * 5 mm/year
= 5,000,000 mm
In meters this is:
= 5,000,000 / 1,000
= 5,000 meters east
Because the Amur and the Eurasian plates are moving apart, the ocean would have to fill up the space left which would lead to the development of a new ocean floor.

The complement pathway is a critical mechanism for eliminating microbes, and is comprised of more than 30 proteins that are constitutively produced. Many of these proteins are synthesized as inactive pro-enzymes, and become active proteases when they are cleaved by an upstream member of the complement cascade. Importantly, the initiation of the complement cascade does not rely on the presence of antimicrobial antibodies, as:___________. 1. any antibody can activate the complement cascade, regardless of whether it has bound the pathogen 2. complement activation will induce antibody production 3. antibody-independent pathways of complement activation rely on complement components that directly bind to microbial surfaces 4. the pathway can still induce inflammation even in the absence of initiating signals to activate the complement cascade
Answer:
3. Antibody-independent pathways of complement activation rely on complement components that directly bind to microbial surfaces.
Explanation:
There are three pathways of complement activation:
The classical pathway.The alternative pathway.The lectin pathway.The classical pathway is triggered by binding of C1 either to the pathogen surface or to antibody bound to the pathogen.
The alternative pathway is triggered by the spontaneous hydrolysis of soluble C3 to C3(H₂O) and initiates eventual deposition of C3 convertase on microbial surfaces.
The lectin pathway is triggered by the binding of mannose-binding lectin or ficolins to carbohydrate residues in microbial cell walls and capsules.
