Consider the following chromosomes and if they are affected by hemophilia.
X = unaffected X chromosome, x = X chromosome affected by hemophilia, and Y = Y chromosome.
If an Xx female and XY male have children, what fraction of their offspring will have an affected chromosome, and what fraction is likely to be affected by hemophilia?
(1 point)
A. 1/4 and 1/2
B. 1/2 and 1/4
C. 1/2 and 1/3
D. 1/4 and 1/4
I've been stuck on this question for a while, may someone please assist?
Answer:
B. 1/2 and 1/4
Explanation:
Hemophilia is a rare disease that has to do with the inability for blood to clot. It is inherited on the X chromosome, hence, it is said to be X-linked. It is usually passed from mother to son. According to this question;
X - unaffected X chromosome
x = X chromosome affected by hemophilia
Y = Y chromosome
Therefore, in a cross between a Xx female (carrier) and a XY male (unaffected), the following chromosomes will be present in the gametes produced by each parent:
Xx- X and x gametes
XY- X and Y gametes
Using these gametes in a punnet square (see attached image), offsprings with genotypes: XX, Xx, XY and xY will be possibly produced.
XX (1) - unaffected female
Xx (1) - unaffected but carrier female
XY (1) - unaffected male
xY (1) - affected male (have hemophilia)
Based on the questions;
- 2 out of the possible 4 children will have the affected chromosomes i.e. both xY son and Xx daughter have the affected (x) chromosome. Hence, the fraction is 1/2
- 1 out of the 4 possible children is affected by hemophilia, which is the xY son. Hence, the fraction is 1/4.

1.A virus mutates, and therefore it has which of the following traits of living things?(1 point)
It uses energy
It evolves.
It grows and develops.
It is made of cells.
2.Compare a virus to a unicellular organism.(1 point)
Viruses reproduce through asexual reproduction; unicellular organisms need a host cell.
Neither unicellular organisms nor viruses respond to stimuli.
Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.
Viruses need energy; unicellular organisms do not need energy.
3.Summarize the lytic cycle.(1 point)
A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.
A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.
The viral DNA incorporates itself with the host cell’s and replicates whenever the host cell replicates itself.
A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
4.Differentiate between the lysogenic and lytic cycles.(1 point)
The host cell copies its own DNA during the lytic cycle.
The host cell is destroyed during the lytic cycle.
The virus injects DNA into the host cell during the lysogenic cycle.
Viral proteins are synthesized during the lysogenic cycle.

3. A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
4. The host cell is destroyed during the lytic cycle.
5. They should get the flu vaccine because their bodies do not build up resistance.
Explanation:
These are the answers I chose from when i did it 10 minutes ago, they wont let me go back to the quick check to confirm it, but this was the best I could do.
The trait of living things that's depicted by a virus that mutates is that it evolves.
The difference between a virus and a unicellular organism is that Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.
The lytic cycle is when a virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
The difference between the lysogenic cycle and the lytic cycles is that the host cell is destroyed during the lytic cycle.
The reason why doctors recommend people, especially the elderly and those with weak immune systems, get the flu vaccine every year is because they should get the flu vaccine because viruses mutate.
It should be noted that when a virus mutates, it shows its ability to evolve. In such a case, there's transformation and development regarding the virus.
People are advised to get the flu vaccine every year because viruses mutate. In this case, getting the flu vaccine will help protect the person from the virus.
Getting a flu vaccine is vital especially for the people that have a low immune system as well as for the older people who are already weak.
In conclusion, the correct options are B, C, D, B, and A.

At temperatures higher than the maximum growth temperature for an organism:
a. proteins are permanently denatured. membranes become too fluid for proper function.
b. hydrogen bonds within molecules are broken.
c. hydrogen bonds are broken and proteins are permanently denatured.
d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Answer:
The correct answer is option d, that is, hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Explanation:
The maximum growth temperature refers to the highest temperature at which growth can take place. Let us take an example of bacteria, it is found that each bacterial species possess a requirement of specific growth temperature, which is mainly determined by the requirement of the temperature of its enzymes. Each of the organism exhibits an optimum growth temperature, a minimum growth temperature, and a maximum growth temperature.
When for an organism, the temperature goes more than its maximum growth than it results in the dissociation of the hydrogen bonds, denaturation of the proteins, and even the membranes become too fluid. This can even result in the death of the species. However, there are some of the organisms, which can thrive high temperatures known as thermoduric organisms, but they fail to grow effectively at such temperatures.
what is role of the stomach in the human digestion system
Explanation:
The stomach is a hollow organ, or "container," that holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a usable form. Cells in the lining of the stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process. When the contents of the stomach are processed enough, they’re released into the small intestine.
Answer:
first the stomach secretes the gastric juice which is made up of digestive enzymes and digest the hydrochloric acid and plays a big role in digesting nutrients.

Why is The sun is the ultimate source of energy
for all living organisms.'
Answer:
"Sun is the ultimate energy source for all living organisms."
✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings. Carnivores indirectly depend on plants for their food. So, if Sun is not there there will be no life on earth.
✴Secondly, sunlight is a good source of Vitamin-D.
Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease in which the bone tissue doesn't properly mineralize, leading to soft bones and skeletal deformities. So if sunlight is not there it can result in loss of Vitamin-D which can cause deficiency diseases.
✴If sunlight is not there there will be no day on Earth. Light will not reach our Earth. Every time there will be only darkness.

Malcolm altered an experiment to be able to reach his desired conclusionResponsible behaviors are those that support responsible scientific practices and do not jeopardize the objective nature of research. Every data during experiments must be well kept and after thorough analysis, results must be published fro the public to see irrespective of whether it agrees or disagrees with the original hypothesis.
Altering an experiment in order to achieve the desired result is grossly irresponsible, as this eliminates the objectivity that should be the main goal of every experiment. Bias must be eliminated from every scientific experiment.
