Explanation:
Mutations introduce novel variety in a population.
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
Further Explanation:
During reproduction other events, such as crossing over during meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

Answer:
34 calories
Explanation:
One gram of carbohydrates provides total= 4 calories.
2 grams of carbohydrates would provide= 4 x 2 = 8 calories.
One gram of protein provides total= 4 calories.
2 grams of protein would provide= 4 x 2 = 8 calories.
One gram of fat provides total= 9 calories.
2 grams of carbohydrates would provide= 9 x 2 = 18 calories.
Total calories from food that gives two grams each of fat, carbohydrate, and protein= 8 + 8 + 18 = 34 calories.
Answer:
Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
The skin has three main functions: Protection; Thermoregulation; Sensation.
The skin acts as a protective barrier from:
Mechanical, thermal and other physical injury;
Harmful agents;
Excessive loss of moisture and protein;
Harmful effects of UV radiation.
Answer:
Compound Umbel.
Explanation:
Celery is more of an annual crop which is a herbaceous plant usually 60 to 120 cm high with white Flowers.
The Celery plant belongs to the Apiaceae and they are known to be mainly Annual.
Morphology or the shape of the Celery plant is that of a Compound Umbel, in which all Umbel inflorescences arises from a common point and appears to be at the same level.They change from
elongated axes (racemes and panicles) to flattened axes (corymbs and umbels) which results in inflorescences thereby making the flowers been arranged closely together. This close association encourages efficient pollination,and the extreme condensation of the inflorescences, as in the
head, gives rise to an inflorescence that appears
to be a single flower and example of such happen to be the sunflowers commonly found around us.
