The correct answer for this question is (A) Groups of cells form tissues.
In multicellular animals, a group of similar cells alongwith inter-cellular substances perform a specific function. Such an organization is called tissue. All complex animals consist of only four basic type of tissues. These tissues are organized in specific proportion and pattern to form an organ like stomach, lung, heart and kidney. When two or more organs perform a common function by their physical and/or chemical interaction , they together form organ system, eg., digestive system, respiratory system, etc. Cells, tissues, organs and organ system split up the work in a way that exhibits division of labour and contribute to the survival of the body as whole.

i hope this helps u i m not sure about the answer though
Answer:
A cell is the smallest basic unit of life, it is the fundamental unit of life that can replicate to give other cells. Tissues is a group or a collection of cells that have been specialized to perform a specific function. There are four main types of tissues in humans namely, connective tissues, epithelial tissues, muscle and nervous tissue. A group of tissues then forms an organ and then several organs forms an organ system
Explanation:
Answer:
The frequency of recessive allele should be 0.30.
Explanation:
According to Hardy-Weinberg equilibrium, sum of both dominant allele frequency (p) and recessive allele frequency (q) should be equal to 1 (p+q = 1).
Brown hair = dominant (p)
white hair = recessive (q)
49% mice are brown hair
so dominant genotype frequency = 0.49
According to Hardy-Weinberg principle, square root of the genotype (homozygous) is equal to allele frequency.
√p =√0.49 = 0.70
The dominant allele frequency is 0.7
Now, by this value we can find the recessive allele frequency by
p + q = 1
1 - 0.7 = 0.3
So, the recessive allele (white hair mice) frequency is 0.30.
