Answer:
Nucleic acids
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleic acids found in the nuclei of living cells. They are the vehicles of genetic inheritance.
Nucleic acids are condensation polymers of nucleotides. To understand their functions you will find it helpful to look at how their molecules are built up and the structures of these molecules.
Explanation:
The answer is they produce endospores.
Explanation:
The endospores are dormant, non-reproductive, tough bacterial spores that ensure the survival of bacteria in adverse conditions.
During the environmental stress, such as starvation, desiccation, radiation and chemical treatment many bacteria form dormant endospores. These endospores germinate again when the conditions become favorable.
Hence, if drought conditions lead the stream to dry up, the bacteria that live there would produce endospores to survive.
Solution :
In Gizmo experiment, when both the intensity of light and carbon dioxide level is high, the rate of photosynthesis will maximize.
A). If the temperature is too hot or cold, it becomes difficult to find the ideal intensity of light because if the temperature is hot, the light intensity will be too high and thus the chlorophyll will get damaged. While if it too low, then it will be difficult for the proper functioning of the cells. And hence the photosynthesis will not take place.
B). It will be considered as a limiting factor if the light intensity is low. With light intensity being low, it will be difficult for the plant for survival and ideal carbon dioxide level will have no role. This amount of carbon dioxide does not help the plant to survive as the light intensity is now a rate limiting factor.
The possible scenario for singing traits in female birds will be about 26% in Generation 4 species
Explanation:
Singing trait have been common among both male and female birds and it is an ancestral traits. However, singing has been more sex-specific with male birds. Reasons for which birds generally sing are:
- To attract the mates
- While making nests and laying eggs
- For the young birds to recognize their parents
However, various studies prove that the singing trait in female birds is reducing with increase in non-singing female birds over the years due to evolutionary course.
<span>According to the ipat model, technology that enhances our acquisition of minerals, fossil fuels, timber, and ocean fish increase environmental impact.
IPAT is a model or equation which expresses that
I (stands for Environmental impact) is the product of three factors: P (stands for population), A (is affluence) and T ( for Technology).
IPAT can be written as (I=PAT) or I = pxAxT</span>
