Answer:
Genotype of long winged fly is Ll
Genotype of short winged fly is ll
Explanation:
Given
Allele for long wing trait is "L"
Allele for short wing trait is "l"
When a long winged fly is crossed with a short winged fly, half of the offspring have long wings and other half have short wings as the ratio is 
Let us say that the genotype of long winged fly is Ll
and the genotype of short winged fly is ll
The cross between the two will produce following offspring
Ll * ll
Ll, Ll, ll, ll
Out of four off spring two have long wings (Ll)
and the other two have short wings (ll)
Thus the ration of long to short wing offspring is 
i.e
-Homeostasis:maintains stable internal conditions
-Metabolism:cellular respiration
-Growth:biosynthesis
-Made of cells:mitosis and differentiation
-Responds to changes in environment:plant bending towards light
Answer:
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.
Explanation:
Answer:
A sharp knife can cut objects more easily compared to a blunt knife because a sharp knife applies more pressure on the object.
The study of heredity which is a biological process where a parent passes certain genes (traits) onto their offspring. <span>Heredity is the process that makes variations between individuals causing the evolution of species by natural selection. Inherited traits are controlled by one or more genes The study of heredity in biology is genetics.</span>
