Answer:
All of the above are true.
Explanation:
Microbial cells are surrounded by the plasma membrane or cytoplasmic membrane. It serves as a selective barrier allowing materials in and out of the cell e.g. allowing nutrients in and waste out.
Microbial cells grow independently, in that they are unicellular, and so do not depend on the other cells to carry out the process. However, they rely on nutrients, and in some environments, these may be nutrients produced by other organisms.
Microbial cells are unicellular, although some microorganisms are multi-cellular. Microorganisms such as bacteria are unicellular, that is, exist as single cells.
Bacteria and viruses are microorganisms.

Answer:
It is both accurate and precise.
Explanation:
Accuracy and precision are two ways data measurements are described. A measurement is said to be ACCURATE if it is close to the accepted/correct value while PRECISE measurements are those measurements that are close to one another.
In this case, the correct value is 59.2
From observation of the experimental values:
Trial 1: 58.7
Trial 2: 59.3
Trail 3: 60.0
Trial 4: 58.9
Trial 5: 59.2
- One would notice that these measurements in each trial is close to the correct value of 59.2, hence, they are said to be ACCURATE.
- Also, the measurements are close to one another, hence, they are said to be PRECISE
in a nutshell, the data is both accurate and precise
A curvy figure is not a universally accepted sign of physical attractiveness. Therefore option “B” is correct.
It is the measure of the degree to which a person can look and aesthetic pleasing. Facial symmetry and sociocultural and personal choices of a person are evaluating factors.
Facial symmetry is based on the symmetry of the face of a person and youthfulness. It helps in determining the beauty of a person.
Sociocultural depend on how a person combines both social and cultural factors. Factors affecting are such as personal beliefs, and values. Personal choices vary from person to person as everyone has different choices.
Physical attractiveness is the evaluation of the physical appearance of a person.

Answer:The answer is B.curvy figure
Explanation:
In population individuals where 149 have the A1A1 genotype, 18 have the A1A2 genotype, and 154 have the A2A2 genotype, so the allele frequency of A1 is 0.49.
The incidence of a gene variant within a population is represented by the allele frequency. Alleles are different versions of a gene that share the same genetic locus on a chromosome.
To determine the allele frequency of A1
There is the formula:
frequency of A1 = (2 x number of A1A1) + Number of A1A2/ 2 x population
so, A1A1 = 149
A1A2 = 18
Population = 149 + 18 + 154 = 321
The frequency of A1 = (2 x 149) + 18/ 2 x 321
hence the frequency of A1 = 0.49
Therefore, the allele frequency of A1 is 0.49.

Answer:
Either the color will disappear or the brightness of the color will reduce as compared to the brightness in normal case.
Explanation:
Non diffusible red pigment known as prodigiosin is a characteristics of S. Marcescens. Since, the red pigment is dependent on least 10 enzymes, it is clear that the pH and temperature range must be adequate for these enzymes to be functional. The optimum condition for pigment formation is 30 degree temperature and alkaline medium.
If any of the 10 enzymes become non-functional, the chances of attaining normal bright red color are not possible. Either the color will disappear or the brightness of the color will reduce as compared to the brightness in normal case.
a crystal is any solid that has an organized structure. ... minerals are inorganic, naturally occuring substances that have crystalline structures. so it is a prerequisite to be a crystal in order to be a mineral. all minerals, therefore, form crystals.
