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
Answers
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.
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
Answers
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.

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.
Answers
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.

Answers
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.

Answers
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

Algae are photosynthetic protests that act similar to plants since they can make food for themselves es. What factors must be present for algae to grow densely or in abundance?
Answers
Answer:
Carbon dioxide, water, sunlight.
Explanation:
Photosynthesis uses the energy in sunlight to drive the reactions that produce glucose. These reactions are necessary for the algae to produce food, continue to survive, and grow.
As well as sunlight, photosynthesis requires carbon dioxide and water as reactants. The reaction produces glucose and releases oxygen as a byproduct.
The algae need an adequate supply of all of these reactants to grow in abundance.
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
Answers
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.
