Answer:
Explanation:
in this case female parent XX is hetrozygous for round nose. when a cross between round nose father XY and hetrozygous round nose mother takes place and suddenly a chromosomal nondisjuction occurs, the chromosomes carrying genes for pointed tip nose come togather in a gamete and a gamete (egg) with XX chromosomes is appeared having 24 chromosomes instead of 23. when this gamete fertilizes with a sperm having normal 23 chromosomes and only carry Y chromosomes, a pointed nose klienfelter syndrome case will appear.

What are the products when a DNA molecule replicates?
A two molecules of DNA each made of a paired sequence of bases
B two molecules of DNA each made of a paired sequence of nucleotides
C two strands of DNA each made of a paired sequence of bases
D two strands of DNA each made of a paired sequence of nucleotides
(Its NOT c.)
The products when a DNA molecule replicates are two molecules of DNA each made of a paired sequence of nucleotides. The correct option is B.
What is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.
Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
The fundamental mechanism of DNA replication is similar across all organisms, making it a crucial operation.
Two DNA molecules, each consisting of a paired sequence of nucleotides, are produced when a DNA molecule duplicates.
Thus, the correct option is B.

A farmer is trying to increase the diversity of corn kernel color in his crops. The trait for corn color is controlled by two alleles. Yellow corn (B) is dominant over white corn (b). Which combination of corn should he cross to get the most variety of genotypes for corn color in the next generation?
A. BB x BB
B. Bb x bb
C. Bb x Bb
D. BB x bb
Answer:
C
Explanation:
If the farmer crosses Bb x Bb, then the progeny will have BB, Bb and bb genotypes attributing to increased diersity of corn kernel color in his crops.
What is a genotype?The total complement of an organism's hereditary material is referred to as its genotype. The alleles or variants that an individual carries in a specific gene or genetic region are also referred to as their genotype. Genotype is another term for them.
There are three distinct categories of genotypes: heterozygous recessive (pp), heterozygous dominant (PP), and homozygous recessive (pp). Both the dominant homozygous genotype and the dominant heterozygous genotype exhibit the same characteristics.
Therefore, if the farmer crosses Bb with Bb, the offspring will have BB, Bb, and bb genotypes, which will contribute to an enhanced diversity of corn kernel color in the farmer's harvests.

How can you use genetics to study human inheritance?
Answer:
by analyzing how genes influence the development of phenotypic traits, i.e., by determining the association between phenotypic traits and changes in DNA sequence
Explanation:
Genetics is a discipline that studies how genetic variation, i.e., the variation in the Deoxiriibunicleinc acid (DNA) molecule, is associated with the transmission of heredity, and how the environment influences this process. The DNA is a molecule that carries the instructions to perform all metabolic functions (eg., reproduction, development, growth, etc). Thus, advancements in genetics enabled us to decipher how phenotypic traits pass from parents/ancestors to their offspring/descendence. Genes are segments of DNA that carry the information (genetic information) to determine each phenotypic trait. During reproduction, genes are passed from one generation to the next, thereby transmitting this information across generations.

You design an experiment to test the hypothesis that consuming caffeine increases a person's chances of developing a headache. Participants in the experimental group will be told to drink 8 ounces of caffeinated soda in the morning once a day for 10 days, and to abstain from drinking any other caffeinated beverages or soda. Which of the following is an appropriate control group for your experiment?
a) A group that drinks 8 ounces of decaffeinated hot coffee (no caffeine) in the morning once a day for 10 days and abstains from drinking any other caffeinated beverages or soda
b) A group that drinks 8 ounces of caffeinated soda once a day for 10 days in addition to their normal beverage habits
c) A group that drinks 8 ounces of decaffeinated soda (no caffeine) in the morning once a day for 10 days and abstains from drinking any other O caffeinated beverages or soda.
d) A group that does not drink soda (caffeinated or decaffeinated) or other caffeinated beverages for 10 days
Answer:
d) A group that does not drink soda (caffeinated or decaffeinated) or other caffeinated beverages for 10 days
Explanation:
In an experiment, two groups exist as follows: experimental group and control group. Experimental group is the group that receives the experimental treatment (independent variable) while the CONTROL GROUP is the group that does not receive the experimental treatment.
In this experiment, the experimental treatment is the CAFFEINATED SODA (contains caffeine). Hence, the appropriate control group for this experiment will be the group that does not drink any soda (whether caffeinated or decaffeinated) or other caffeinated beverages for 10 days.
All of the following are reasons it might be beneficial for prokaryotes to take up foreign DNA EXCEPT that Question 77 options: a) DNA could be used for food by bacteria. b) the uptake of foreign DNA would result in potentially beneficial recombinants. c) the uptake of foreign DNA might allow a cell to repair damaged chromosomes. d) the uptake of foreign DNA could allow completely new genes with new functions to enter the recipient cell. e) the uptake of foreign DNA could result in the breakage of the plasma membrane of the recipient cell.
Answer:
dna could be used for food by bacteria
Explanation:
not a beneficial reason
All of the following reasons are beneficial for prokaryotes to take up foreign DNA except the use of DNA as food by bacteria. Thus, the correct option is A.
What is DNA uptake?DNA uptake is defined as the conversion of exogenous, DNase-sensitive DNA into a DNase-protected state inside a bacteria. In gram-negative bacteria, this DNA uptake can be achieved by crossing the outer membrane. By contrast, in gram-positive bacteria, DNA uptake is similar to gram-negative bacteria with passage across the cytoplasmic membrane.
The uptake of DNA in bacteria is beneficial as it helps in the production of recombinants that can be used for various purposes. The DNA uptake can be used for the repairing of damaged DNA and chromosomes in patients of genetic disorders.
New genes with different functions can be introduced in organisms like bacteria.
Therefore, the correct option is A.

Answer:
They are pollinators.
Explanation:
Bees are vital to our ecosystem because they are pollinators and due to this pollination, these bees are responsible for the presence of trees, shrubs and other small plants etc. if bees were to disappear from ecosystem Earth then the whole world is adversely affected because trees can't produces fruits and seeds so after sometime animals die due to unavailability of food. Human activities are responsible for the death of these bees because human activities causes pollution which is not good for bees. We have to make a safe place for bees and grow as many flowers as you can in order to increase their population.
