Answer:

true

Explanation:

A gene mutation is a permanent change in the DNA sequence of a gene. Mutations can occur in a single base pair or in a large segment of a chromosome and even span multiple genes. Mutations can result from endogenous (occurring during DNA replication) or exogenous (environmental) factors. Germline mutations occur in gametes. Somatic mutations occur in other body cells. Chromosomal alterations are mutations that change chromosome structure. Point mutations change a single nucleotide.

Two major categories of mutations are germline mutations and somatic mutations.

Germline mutations occur in gametes. These mutations are especially significant because they can be transmitted to offspring and every cell in the offspring will have the mutation.

Somatic mutations occur in other cells of the body.

An egg of mass 0.060 kg is dropped from the top of a building. Just before it reaches the ground, it has a total kinetic energy
3241004551 [841]

The velocity is 14 m/s

The parameters given on the question are

mass= 0.060 kg

kinetic energy= 5.9 joules

K.E= 1/2mv²

5.9= 1/2 × 0.060 × v²

5.9= 0.5 × 0.060v²

5.9= 003v²

v²= 5.9/0.03

v²= 196.66

v= √196.66

v= 14 m/s

Hence the velocity of the egg before it strikes the ground is 14 m/s

Answer:

y = 9.64 m

Explanation:

This exercise should be solved using kinematics in one dimension, let's write the equations for the two cases presented

The rock is released

         y = y₀ + V₀₁ t₁ - ½ g t₁²

In this case the speed starts is zero

         y = y₀ - ½ g t₁²

The rock ​​is thrown up

       y = y₀ + v₀² t₂ -½ g t₂²

The height that reaches the floor is zero

       y₀ - ½ g t₁² = y₀ + v₀₂ t₂ - ½ g t₂²

We use the initial velocity with the equation

         v₂² = v₀₂² - 2 g y

At the point of maximum height v₂ = 0

         v₀₂ = √ (2 g y_{max})

        g (-t₁² + t₂²) = 2 √ (2 g y_{max}) t₂²

        g (- 4.15² + 6.30²) = 2 √ (2 2 g) 6.3

        g (22.4675) = 25.2 √ g

        g² = 2²5.2 / 22.4675 g

        g = 1.12 m / s²

Having the value of g we can use any equation to find the height

        y = ½ g t₁²

       y = ½ 1.12 4.15²

        y = 9.64 m
