Answer:
%50
Explanation:
Heterozygous = 2 different alleles (Tt)
4 leaf clover = 2 recessive alleles (tt)
T is dominant over t, so with the combination of Tt three leaves are expressed, rather than four leaves
For a recessive trait (four leaves) to show 2 recessive alleles are needed
To find the percentage of the offspring to have four leaves a punnet square should be created
To find the percentage divide the number of four leaf offering with 4 and multiply by 100
2÷4×100=50
= 50%
Answer:
Hydrogen ions
Explanation: pH is the concentration of hydrogen ions (H+) in a given solution. A pH of 1 means there are a lot of hydrogen ions and a pH of 14 means there is a very small concentration if them.
Answer;
As liquid water freezes, the molecules arrange themselves in a way that takes up more space than liquid water. What would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules? A).The density of ice would be greater than the density of liquid water, and ice would not float. B). Ice would form in layers, and liquid water would get trapped in between the layers. Liquid water would have a higher specific heat, making it less likely to undergo vaporization. C).The freezing point of water would decrease, making ice more difficult to form.
<u>Answer</u>:
Once a human is infected with a virus, bacterium, fungus, or parasite they interfere with the human’s normal body function
.
<u>Explanation</u>:
The infection due to the pathogen are not always end up as a disease. Infection occurs when any pathogen comes inside the human body it can be virus, bacteria or can be fungus, and starts multiplying by getting suitable environment as well as the host. The microbes sometimes challenges the immune system and lowers the resistance power the body. So, as viruses does by killing the fighter cells and also by disrupting the general cell functions.
Answer:
Bacteria converts the nitrogen into fixed nitrogen which can then be used by plants.
