Answer:
Hematopoietic stem cells (HSCs) are the stem cells that give rise to other blood cells. This process is called haematopoiesis. This process occurs in the red bone marrow, in the core of most bones. In embryonic development, the red bone marrow is derived from the layer of the embryo called the mesoderm.
Explanation:
Function: Stem cells that give rise to other blood ...
Location: Bone marrow
System: Hematopoietic system

Explanation:
Antibiotic resistance can vary within a population of bacteria. The diagram below represents the changes in a population of bacteria as a result of exposure to antibiotic over time.
Explain how this is an example of natural selection, and why we can use this as evidence that evolution occurs.
Answer:
The resistance that some bacterial populations develop to an antibiotic is an example of natural selection because the individuals with more resistance are those that survive, being an evidence of evolution since resistance can be inherited to the following generations.
Explanation:
The resistance to antibiotics that bacteria develop is the best example of how natural selection and evolution occurs, especially because of the fast and easy reproduction of these microorganisms.
In the example it can be seen that only the the most resistant bacterial populations to the antibiotic survive over time. Antibiotic resistance is due to mutations developed by bacteria that modify their structure and function so that they are not affected by an antimicrobial. According to natural selection, these mutations make resistance an inherited trait, and future generations will not be sensitive to the effect of the drug.
Why does natural selection occur? Only resistant individuals survive the effect of the antibiotic.
How do you explain evolution? Successive generations of bacteria have evolved, through mutations, to resist the effect of an antibiotic.
In the following list of infections, two of these are mentioned in the video clip that are caused by bacteria. Place a “B” by the two infections that are caused by bacteria. The other two infections are not mentioned in the video clip as they are not caused by bacteria. Place a “V’ by these as they are viruses and not bacteria.
_____ Common Cold
_____ Tooth Decay (resulting in root canal)
_____ Strep Throat
_____ Influenza (“flu”)
Answer:
Explanation:
V Common Cold
B Tooth Decay (resulting in root canal)
B Strep Throat
V Influenza (“flu”)
Strep throat is caused by streptococcus which is a bacteria. They are present but can grow in numbers due to other problems in the body.
Tooth decay is caused by bacteria and that is why we should avoid feeding them with sweets so they don't grow in numbers.
Influenza is a virus that causes the flu. We have a flu season each year and a vaccine against it.
The common cold is also caused by a virus and there are a few of them that cause the same kinds of symptoms.

Explanation:
During the light dependent reaction,_____ is oxidized to form oxygen. During the light independent reaction, _____
Is reduced to form glucose
Answer:
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.

Answer:

Explanation:
diversity increases the chances that individuals will possess favorable traits needed to survive changing environmental conditions
Answer:
True
Explanation:
When we have a narrow gene pool for our offspring that narrows down the favorable traits that the offspring can have. This can lead to the offspring having more traits that are not so good in its family tree and leave it not suited for a given environment. On the other hand, if the diversity is large it will lead to more offspring having more favorable traits and more adaptation to their environment.
- Why does a male bird displays his colorful feathers? (1 point)
O to increase the success rate of asexual reproduction
to increase the gestation period
to release gametes into his surroundings
O to attract a mate
Answer: To attract a Mate

Scientists are creating a new variety of corn. They have two requirements: the new corn must resist pests and it must contain vitamins. What method will they most likely use to create this corn?
a. insert a gene from one cell into another
b. insert a gene from one organism into another
c. remove cell walls of plant cells in culture
d. remove a gene from a plant cell
Answer:
i think the answer is b.
Answer:
insert a gene from one organism into another
Explanation:
they must transfer a gene that is able to fight against pests, while also containing vitamins, to do this they'd need to transfer a gene with these traits from one organism into another
