Explain why it is not possible to change hereditary conditions.

lukranit [14]

Answer and Explanation: Before answering your question, let me explain to you what actually heredity is. Newborn babies inherit some traits from their parents both from mother and father in form of chromosomes, which is present in the nucleus of human cell. Human has 46 chromosomes in total in form of 23 pairs. When a baby is made he get 23 chromosomes from each parents thus, inheriting their traits through chromosomes. These traits lie on the surface of chromosomes as a functional unit called Genes. It is made up of DNA which we referred to as the genetic material of human being. Now, you can see how complicated this loop is and this loop is part of each and every cell of your body and you have millions and trillions of cell in your body,because you cannot get rid of your DNA which means cannot take out the heredity from within your body. You always get the traits you receive from your parents and you cannot change those traits. Hereditary conditions include some of genetic diseases we receive either from our parents through chromosomes or those diseases are caused because of mutation of genes which is kind of problem in your genes. Because you cannot replace all this system, thus you cannot take out hereditary condition out of your body.

A boat is 4.0meters long and 2.0meters wide. Its water line is 1.0meter from the bottom of the boat; it is submerged to this wat

Mademuasel [1]

Answer:

option A

Explanation:

given,

Length of boat = 4 m

width of boat = 2 m

height up to which water is displaced = 1 m

Volume of water displaced by the boat

V = L x B x H

V = 4 x 2 x 1

V = 8 m³

buoyant force acting on the boat

F_b = ρ g V

m g = ρ g V

m = ρ V

ρ is the density of water which is equal to 1000 Kg/m³

m = ρ V

m =1000 x 8

m = 8000 Kg

hence, mass of the boat is equal to 8000 Kg

so, the correct answer is option A

A spring has a spring constant of 450 N/m. How much must this spring be stretched to store 49 J of potential energy?

statuscvo [17]

Answer:

W = 1/2 K x^2

x^2 = 2 * W / K = 2 * 49 J / (N/m) = .218 / m^2

x = .467 m

Pls answer this question from physics

KatRina [158]

1. Anil leaves home at 0905

2. Anil stays at the park for 10 mins.

3. The distance of Anil's home from the park is 7 km

4. Anil's speed is 14 km/h

The question is a distance-time graph

<h3>What is a distance-time graph?</h3>

A distance-time graph show the relationship between distanced moved by an object and time.

<h3>1. When did Anil leave home?</h3>

Anil left home at the time when the distance is zero. That is, the time at which the graph cuts the time axis. That time is 0905.

So, Anil leaves home at 0905

<h3>2. How many minutes did Anil wait at the park?</h3>

Anil waited at the park when her distance is constant. That is the part of the graph that is parallel to the time axis.

It starts at 0935 and ends at 0945. So, the time anil stays at the park is t = 0945 - 0935 = 10 min.

So, Anil stays at the park for 10 mins.

<h3>3. What is the distance of Anil's home to the park?</h3>

The distance from Anil's home to the park is the maxiimum distance she moves until she reaches the park. From the graph, this is 7 km.

So, the distance of Anil's home from the park is 7 km

<h3>4. What was Anil's speed in his journey to the park?</h3>

Anil's speed in his journey to the park is the gradient of the first slopy line between the points (0905, 0) and (0935, 7)

The gradient, m = (d' - d)/(t' - t) where

(d,t) = (0905, 0) and
(t', d') = (0935, 7)

So, m = (d' - d)/(t' - t)

= (7 km - 0 km)/(0935 - 0905) min

= 7 km/30 min

= 7 km/30 min × 60 min/1 hr

= 7 km × 2/hr

= 14 km/h

So, Anil's speed is 14 km/h
