Answer:
Large groups of the same type of cell, all working together for one purpose.
Explanation:
Human tissues are the group of cells that work together to perform a specific function. In tissues, similar type of cells combine together for performing similar function. The cells in tissue are same type means same size and structure. When a group of tissue combine together, it forms organ. These tissue can be broken down into simpler substances which are the cells that are considered as the basic unit of life.
The correct answer for the question that is being presented above is this one: "(3) all cells in his body." A man is exposed to large amounts of ultraviolet radiation while sunbathing on the beach. This exposure causes genetic change in the DNA of a skin cell. In the future, this change can be passed on to (3) all cells in his body.
Here are the following choices:
(1) his male and female children
(2) his male children, only
(3) all cells in his body
(4) his skin cells, only
Answer:
Explanation:
Given
Crossing of a black chicken and a white chicken
Required
The probability of having erminette chicks
The genotype of a black chicken is represented as: BB
The genotype of a white chicken is represented as: WW
The genotype of an erminette chicken is represented as: BW
Using a Punnett square, we have:
The result of crossing the two chicken gives 4 BW out of a total of 4
i.e 4 erminette chickens out of 4 possible chickens
So, the probability is:
Represent as percentage:
