kirza4 [7]

Answer:

<h2>The answer is 3.2 g/L</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass of cat = 400 g

volume = final volume of water - initial volume of water

volume = 125 - 100 = 25 L

The density of the cat is

density =  \frac{400}{125}  =  \frac{16}{5}  \\

We have the final answer as

<h3>3.2 g/L</h3>

Hope this helps you

What are 4 polygenic traits?.
Veseljchak [2.6K]

In humans, height, skin color, hair color, and eye color are examples of polygenic traits.

A polygene is a member of a collection of non-epistatic genes that interact additively to steer a phenotypic trait, consequently contributing to more than one-gene inheritance, a sort of non-Mendelian inheritance, in preference to unmarried-gene inheritance, which is the core belief of Mendelian inheritance.

A polygenic trait is a feature, which includes height or skin coloration, that is encouraged by way of or extra genes. because a couple of genes are concerned, polygenic developments do not comply with the styles of Mendelian inheritance. Many polygenic traits are also stimulated by means of the environment and are called multifactorial.

Most inherited trends in animals are polygenic. a few examples are: conformation, kind, size, sturdiness, disorder resistance, temperament, velocity, milk and egg production, growth fee, maturation and sexual adulthood rate, and numerous inherited diseases.
