Answer:

Mendel was an Austrian monk whose researches laid the foundation of genetics. The experiments conducted by Mendel led him to the foundation of two laws which are named as the law of segregation and law of independent assortment.

According to the law of segregation, the two alleles of a gene segregate during the time of gamete formation and there are 50-50% chances of each of the alleles to be received by the gametes. Hence, there are 50% chances for Y gametes to be produced and 50% chances for y gametes to be produced.

"The growing human population" a. will require an increase in forests and a decrease in agricultural land. b. is best addressed

storchak [24]

Answer:

C. requires the restoration of ecosystems better designed to serve the needs of humans

Explanation:

For a very long time, the survival of plants and animals has been dependent on each other. The plant depended on animals for oxygen and the animals depended on plants for carbon dị oxide.

In recent times, this balance has been altered as humans (higher animals) have started engaging in activities that hurt the ecosystem such as Bush burning, deforestation and other agricultural practices.

In view of this, there is an urgent need for the restoration of ecosystems that suit human needs. This can be done by planting of more trees, reduction in industrial activities that involves emission of harmful gases and wastes into the air, land and water.

What are the three examples to justify Newton first law of motion .

Sergeu [11.5K]

Explanation:

1.Law of Inertia

Inertia : is the ability to resist change in motion.

Example; if you roll a ball it will keep running unless you change it's direction with the help of friction..

2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..

unbalanced force is a type of force where total force≠zero, means the object will move..

Example; if you will try to push a truck will be less but if you push a car the acceleration will be more.. because car has less mass..

3. the third law of motion state that foreign every action there is a opposite reaction..

Example; can you throw a ball on the floor ...the floor pushes back that the ball..
