Answer:
1.Temperature
2.Moisture
3. PH: acidic or basic concentration
Explanation:
Different microorganism grow at different temperature. For example, many human-disease-causing microbes have an optimum temperature of 37C, and most of the bacteria do not grow at temperature higher than 45C. This means that any temperature lower than 45C will favor the growth of certain bacteria while higher temperature may cause death or reduction in the population of most. Hence, the effect of temperature on these organisms.
Water is required to dissolve the cell substances in microorganism just like higher animals. while some can survive under an extremely dry condition, most can't and this could result in death or reduction in population.
PH, a measure of the hydrogen concentration in a solution for most microorganism is between 6-8, too much of acid or base could disrupt the activities of these organisms and a maintained range ensure an optimal survival.
C. Dinosaur footprint as it is the only body part that is stated in the choices.
Hope this helps :)
The shape of chromatin, which can be either open (euchromatin) or compact (heterochromatin), is dynamically regulated during the phases of the cell cycle is the two types of conformations.
- The main distinction between conformation and configuration is that whereas the configurations of the same molecule do not easily interconvert, their conformations do.
- With a predefined location in the nucleus and a certain form, such as metacentric, submetacentric, acrocentric, or telocentric, chromosomes are primarily heterochromatic in this stage.
- All DNA-mediated processes, including gene regulation, can be significantly impacted by the degree of nucleosomal packaging.
- While heterochromatin (tight or closed chromatin) is more compact and resistant to factors that need to access the DNA template, euchromatin (loose or open chromatin) structure is permissible for transcription.

Anxiety, overexcitement, inability to focus, poor coordination, and shaking are common side effects of substance abuse. The class of drugs includes cocaine, nicotine, ecstasy, and amphetamines.However, any drug when used that can cause euphoria or feeling “high” can become a drug of abuse.
