the color of the light
photopigment are unstable pigments that undergo a chemical change when they absorb light
The color of a photopigment is due to the color of light that it reflects.
A pigment absorbs light at a specific range. Every other light not absorbed is reflected by such pigment.The phenotypic color of a pigment is a function of the color of the light it reflects. A photopigment as its name implies is a pigment that has the ability to absorb light to become unstable. An example of pigment and its characteristic color is:Chlorophyll; appears green because it reflects green light and absorbs blue and red.Therefore, the color of a photopigment is due to the color of light that it reflects.Learn more: https://brainly.com/question/17098075?referrer=searchResults

Explanation:
in a punnett square the alleles of all the male gametes are entered in the
a. top of the chart
b. right column
c. left column
d. bottom left box
Answer:
In a Punnett's square the alleles of all the male gametes are entered in the top of the chart (option a).
Explanation:
Punnett square was designed to plot the allele crosses of the parental generation and observe the probable combinations of the alleles in the offspring, for a given characteristic.
Conventionally, in a Punnett square or chart, the father's alleles are placed at the top, the mother's alleles are placed in the left column and the results in the offspring are shown in the boxes, resulting from the intersection of the data.
Holding your breath can only last a limited amount of time because you feel the need to start breathing again. The stimulus that drives this response is mediated by _______________.
A- Decrease in circulating O2 in blood
B- Increase in circulating O2 in blood
C- Decrease in circulating CO2 in blood.
D- Increase in circulating CO2 in blood
Answer: A - Decrease in circulating O2 in blood
Explanation:
To survive, the body needs to supply oxygen to the various cells so that they may use it for respiration. It uses blood as a conduit and acquires oxygen through breathing.
If a person stops breathing, it means that the cells will not be getting enough of the oxygen required to respire. When the oxygen levels get too low, the body will force the breathing to replenish oxygen and keep respiring.
Which statement provides a possible explanation for the growth
pattern shown above?
1) O Manipulation of genes caused the movement of embryonic skin cells.
2)O Exposure to light stimulated the development of cells containing ozone.
3) Uncontrolled cell division occurred as a result of gene mutations
4)An immune reaction triggered the formation of excess blood cells.
Answer:
3) Uncontrolled cell division occurred as a result of gene mutations
Explanation:
Spontaneous modifications within the genome may occur during the process of cell division. When copies of the DNA inside the cell are made, these mutations cause errors; and can include small single nucleotide polymorphisms, and large scale additions or deletions across multiple genes.
Some, like somatic mutations, exist only inside vegetative (body) cells, that cannot be passed onto offspring. This is caused by several factors like
UV radiation, chemical mutagens,infective agentsUV radiation damages strands of DNA, by causing dimers to form; here, consecutive nucleotide bases covalently bond instead of those on the complementary strand. This conformational change causes errors in DNA proofreading and repair mechanisms where bases are not well-incorporated into the strand- tumors (clumps of uncontrolled cell growth) may form, resulting in melanoma, a type of skin cancer.

Answer:
Follows are the solution to this question:
Explanation:
The following are the two considerations demonstrating that there would be less biodiversity than the tropical areas in the Mediterranean climate as well as polar areas.

Which type of cells contain a cell wall?
Answer:
A cell wall is a fairly rigid layer surrounding a cell located outside of the plasma membrane that provides additional support and protection. They are found in bacteria, archaea, fungi, plants, and algae. Animals and most other protists have cell membranes without surrounding cell walls.

Question 10 of 10
Which process takes place first in the development of a human being?
O A. Fertilization
O B. Embryo formation
C. Differentiation
O D. Blastocyst formation
Answer:
A. Fertilization
Explanation:
The development of a human being begins with fertilization, a process by which two highly specialized cells, the spermatozoon from the male and the oocyte from the female, unite to give rise to a new organism, the zygote.

a double helix
b polymer made up of amino acid monomers
c a type of nucleic acid
d four possible nucleotides due to four different nitrogenous bases
e these are all accurate
Answer:
E. All choices are accurate representations of DNA.
Explanation:
DNA consists of a shape like a common known 'Double Helix' which is possible because it is made up of building blocks (chemical) known to us as nucleotides. Nucleotides are made up of monomers such as
phosphate groupa sugar groupOne of four types of nitrogen bases (Four types of nitrogen bases...adenine, guanine, cytosine, or thymine)DNA is a polymer which is, yes, made up of the monomers 'nucleotides'

Even though cancer genomes are overall hypomethylated, explain why some genes are hypermethylated in cancer cells. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. A. DNA repair genes B. OncogenesC. Cell Cycle stop genesD. Are not expressedE. HypomethylationF. HypermethylationG. Are expressed H. protein-coding genes______promoters will lead to reduced expression of the correspondent genes. Some genes such as____and_____need to be expressed. When they______, this can lead to cancer.
Answer:
Hypermethylation of___ promoters will lead to reduced expression of the correspondent genes. Some genes such as Cell Cycle stop genes _and__DNA repair genes_need to be expressed. When they__are not expressed_, this can lead to cancer.
Explanation:
Oncogenes are genes that may trigger cancer, where they are generally overexpressed (i.e., expressed at high levels). Although there are well-documented exceptions to this rule, DNA methylation generally represses gene expression by preventing the binding of transcription factors to promoters. It is known that the hypermethylation of tumor suppressor genes including, for example, cell cycle stop genes and DNA repair genes, may lead to cancer. Similarly, hypomethylation of oncogenes such as, for example, Cyclin D1 (a cyclin-dependent kinase involved in cell cycle progression), may also contribute to carcinogenesis.
In the analysis of quantitative traits, positions on chromosomes called quantitative trait loci (QTLs) are often discussed. In the same context, restriction fragment length polymorphisms (RFLPs) are also discussed. What is the relationship between QTLs and RFLPs
Answer:
RFLP technique can be used to develop useful polymorphic molecular markers for mapping QTLs.
Explanation:
A quantitative trait locus (QTL) is a fragment of DNA whose variation is associated with phenotypic traits controlled by numerous genes (i.e., quantitative traits) such as, for example, height, weight, etc. Restriction fragment length polymorphism (RFLP) is a technique useful to detect DNA polymorphisms (i.e., genetic variation) among samples. In RFLP, the genome is digested using restriction enzymes and these restriction fragments are subsequently separated by electrophoresis depending on their size, thereby producing differential gel bands among samples. These polymorphisms can be used to map QTLs and develop linkage maps, which is known as RFLP mapping.
