adult stem cells
embryonic stem cells
embryonic stem cells
marrow cells
marrow cells
Answer:
hope this helps not sure tho
Explanation:
Fertilization is the union of a male and a female gamete that gives rise to a zygote that is the first cell of the organism. Fertilization occurs in the sexually reproducing organisms. After fertilization , the zygote undergoes continuous division and Gives rise to a mass of cell that later on differentiate into cells that assume specialized function, each group of specialized cell then gives rise to organ system of the organism.

A. Repressor proteins can be activated and bind to regulatory sequences to block transcription.
Explanation:
its A
The best explanation for the prokaryotic expression of a metabolic protein is repressor proteins can be activated and bind to regulatory sequences to block transcription.
What are metabolic proteins?Protein helps with growth and repair. Proteins have the potential to serve as a metabolic fuel source in addition to all of these important functions.
Excess proteins must be converted into glucose or triglycerides and used to provide energy or build energy reserves because proteins cannot be stored.

Which factors affect the gravitational force between two objects?
Answer: The size of each object and the space between them.
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
Populations of caribou show a cyclical fluctuation with predictable patterns in Norway. Reindeer populations are higher in the
southern regions in winter months while populations are higher in the northern regions in the summer months. Infer the cause of
these predictable changes for the Norwegian reindeer populations.

A)
B)
C)
Reindeer migrate from north to south in the winter months to reach more
fertile feeding grounds. They migrate to the north in summer months.
The reindeer migrate from north to south in the summer months to reach
more fertile feeding grounds. They migrate to the north in winter months.
The reindeer populations migrate to an intermediate location in Norway to
mate and then diverge to the northernmost and southernmost regions to
avoid competition for food.
There are two species of reindeer in Norway. The northernmost species
reproduces in the winter, causing an increase in population size. The
southernmost species reproduces in the summer, causing an increase in
population size.

What is the elevation of hachure line A?
100 feet
50 feet
75 feet
125 feet
Because the incorrect answer was 100 feet (based on it being the first lower elevation than the last recorded elevation of 125 feet) And the question prior of What is the most likely elevation of X being 115 feet was also graded incorrect. Would the actual contour lines WITH the hachure lines ON THEM continue to elevate in C.I. 25 increments making the contour line that X is on, 150 feet and the contour line that A is on to be 175 feet? And then 125 feet would actually be the correct answer because it is the first lowest below 175 feet?

Now that we have studied the various types of vaccines, consider the current resurgence of diseases like the measles. How can we convince the general public and possibly even ourselves, that immunization is a necessary preventative measure for diseases that have serious complications? Is there a different schedule that we should consider? Are some forms of vaccines safer than others? Should we spread out the inoculation schedule to prevent confusion of a young person?
Answer:
Immunization is one of the most effective processes of preventing or treating dangerous disease. It should be told and advertise to the general public about the facts and importance of vaccination. Doctors and government should explain the reports and ratio that the people who are taking the vaccination in the proper dose and the right amount of vaccination are about 9 timeless likely to have to the other people. It is essential to get a proper dose and proper amount to avoid the development of resistance.
There are several forms of vaccine and they have a different schedule from each other. Every vaccine is safe but one needs to know the cycles, dose and amount of the vaccine. Yes, we should spread out the inoculation schedule to prevent confusion of a young person.
If an animal has 21 chromosomes before replication, how many do they have after?

You perform an experiment using an aquatic plant to determine which color of light is most effective at driving photosynthesis. You take three plants, immersed under water, place plant A under blue light, plant B under red light, and plant C under green light. You notice bubbles coming off the leaves. More bubbles are coming from plants A and B, than plant C. How do these results determine which color of light is most effective at driving photosynthesis
Answer:
The plants producing more bubbles indicates that photosynthesis is more effectively driven by BLUE AND RED LIGHTS.
Please find explanation below.
Explanation:
According to this question, an experiment is being carried out to determine which color of light is most effective at driving photosynthesis. Three sets of aquatic plants (plants A, B and C) are used for this experiment. Plant A was placed under blue light, plant B under red light, and plant C under green light.
Photosynthesis is the process whereby plants manufacture their food (glucose) using sunlight energy. However, it is worthy to note that OXYGEN GAS is one of by-products of this metabolic process. Hence, as stated in this question, the bubbles noticed to be coming off the leaves is OXYGEN gas.
However, more products in a reaction denotes the fast rate of such reaction. Plants A and B produced more bubbles than plant C. This means that photosynthesis in plants A and B, which released more OXYGEN GAS as BUBBLES, is more effective under the blue and red light respectively.
