Based on the Newton's laws of motion, the motion of an object is due to an unbalanced net force.

<h3>What is Force?</h3>

A force is a push or pull effect which causes a change in the motion or state of an object.

Newton's second law states that the acceleration of an object is to the net force acting upon the object, and inversely upon the mass of the object.

Thus, motion occurs when there is greater net force acting on an object.

From the diagram shown above, when a force of 3000 N is applied by the man, the boxcar does not move because the force applied by the man is less than the force on the boxcar.

The box car will move if a force greater than that on the boxcar were applied to it.

According to Newton's third law of motion, for every force, there is an equal but oppositely acting reactionary force, therefore, the net force on the boxcar is 0 N.

Therefore, the motion of an object is due to an unbalanced net force.

In the 1950s, when Watson and Crick were working on their model of DNA, which concepts were well accepted by the scientific comm
bogdanovich [222]

Answer:

The correct answer will be-

1. Chromosomes are made up of protein and nucleic acid.

2. Genes are located on chromosomes.

3. Chromosomes are found in the nucleus.

Explanation:

Watson and Crick are known for their findings on the structure of DNA in 1953. Their findings were motivated by the book called "What is Life?".

The book stated the concepts which were well accepted by the scientific communities that is the gene determines the trait which is located on the chromosomes proved by the experiments of Morgan.  

The chromosomes are the condensed structure present in the nucleus was suggested by the Nageli in 1884. The chromosomes are composed of nucleic acid and protein was also proved and was well-accepted fact.

But the genes are made up of DNA was not well accepted which was suggested by the experiments of Avery in 1940s.

Thus, the selected options are the correct answer.

Which of the following best illustrates a type I survivorship curve, with higher death rates at older ages? Which of the followi
Rama09 [41]

Answer:

large mammals such as gorillas

Explanation:

The survivorship curves refer to the graphical representation of the proportion of the fraction of survivors or the individuals at a given age.

There are three types of survivorship curves which can be constructed by studying the life history of the organisms.

The type I survivorship curve is the curve which can be formed with the organism which has a high survival rate at the younger and middle age and high death rate at the older age. The type I curve can be characterised by its convex shaped. The type I is showed by the large mammals like gorilla, humans and many others.

Thus, large mammals such as gorillas are the correct answer.

3) Farmer Brown grows corn for a living. One day, Farmer Green suggests to Farmer Brown that he should clone his best corn plant
Elden [556K]
The answer is C) Cloning eliminates the ability to sexually reproduce and provide genetic variability.
In the future, there is no variability in the genes in the clones given that they are the exact copies of the "parent" produce. All should be identical without differences and variations. Although Farmer Brown doesn't want this to happen that's is what he is reluctant to listen to Farmer Green's advice.
