In cats, the long hair trait is dominant and the short hair trait is recessive. What is the chance of a homozygous short-haired
offspring if a heterozygous long-haired male mate with a short-haired?

Answer:
the chance of a homozygous short-haired offspring if a heterozygous long-haired male mate with a short-haired is 50%
Explanation:
The best way to see this is to simply draw a punnett square. As you've said, let's call
S
the dominant trait (short hair) and
s
the recessive trait (long hair):
As shown in the image i uploaded:
As you can see, out of the 4 possible outcomes, 2 will result in short hair, and 2 in long. So, you'd have a chance of getting a short haired cat.

Answer:
D. Weight varies with location, but mass does not vary
Explanation:
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, the weight of an object is given by the formula;
Where;
- m is the mass of the object.
- g is the acceleration due to gravity.
Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.
Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).
<em>Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.</em>
