Pyramid biomass
<span>Pyramid biomass shows how energy are passed at
each tropics level and it is a graphical representation that shows the extents of
biomass per unit area at different tropic level with an ecological system. Also,
biomass is the food available for the next tropic level in a food chain and
they can be used as a source of renewable energy. </span>
The answer is C. large changes in allele frequencies can occur in a short time.
Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms and it decreases genetic variation of the population. In specific circumstances, large and rapid changes in allele frequencies can occur in a short time. The smaller the population, the more susceptible it is to genetic drift.
Answer:
Co-vid-19
Explanation:
I think because since Co-vid-19 is new and nobody knows what the real side effects are, they really can't make any medicine for it. It will take time and if they do make medicine, it will take time to know how It will react and how it will react in the long term.
Answer:
BENEFITS:
The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.
A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.
The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.
LIMITATIONS:
<u>descriptive method of investigation
</u>
It cannot be used to correct variable or be used to determine causes and effect of the problem
<u>experimental method of investigation
</u>
It might create an artificial situation that do not always represent the real life situation
<u>comparative method of investigation
</u>
It is not easy to control other variables that might influence the study
<em>Ngl, I just copy and pasted these answers from another brainly question</em>
Answer:
They are modified by shape, function, or size. They are made to have certain roles in different parts of our bodies. These cells group together to make/form tissues. Then these tissues make up organs that we obviously need. Different specialized cells include blood cells, nerve cells, and reproductive cells.
