HELP PLEASE IM STUCK ON THESE QUESTIONS

Biology
1 answer:
Diano4ka-milaya [45]3 years ago
5 0

Answer:

a = 10 m/s²

F = 2000 N

m = 8.57 Kg

Explanation:

1) What is the acceleration of a 40 kg object pushed with a force of 400 N?

Acceleration of object = ?

Mass of object = 40 Kg

Force on object = 400 N

Solution:

Formula:

F = ma

by putting values,

400 N = 40 Kg × a

a = 400 N/ 40 Kg   ( N = Kg.m /s²)

a = 10 m/s²

2) What is the force on an 800 kg rock being thrown at 2.5 m/s2?

Acceleration of object = 2.5 m/s²

Mass of object = 800 Kg

Force on object = ?

Solution:

Formula:

F = ma

by putting values,

F = 800 Kg × 2.5 m/s²

F = 2000 Kg. m/s²  ( N = Kg.m /s²)

F = 2000 N

3) What is the mass of a ball being rolled at 3.5 m/s2 from a 30 N force?

Acceleration of object = 3.5 m/s²

Mass of object = ?

Force on object = 30 N

Solution:

Formula:

F = ma

by putting values,

30 N = m ×  3.5 m/s²

m = 30 N / 3.5 m/s²   ( N = Kg.m /s²)

m = 8.57 Kg

Which of the following describes the ability of a single gene to have multiple phenotypic effects?
bija089 [108]

Answer:

A, pleiotropy.

Explanation:

Pleiotropy - genes that have multiple phenotypic effects. Remember that phenotype means a physical characteristic caused by a gene, such as eye color or fur patterns.

Incomplete dominance - when neither allele is dominant and they mix together in the phenotype. A popular example is a red flower crossing with a white flower and resulting in a pink flower.

Epistasis - when two genes contribute to the phenotype, but one gene completely masks another gene. An example would be labrador fur colors.

Multiple alleles - 3 or more alternative forms of a gene, but only 2 alleles can occupy an organism. An example is blood type.

Hope this helps!
