What does the theory of evolution contribute to conservation biology?

Answers

Answer 1

Answer: The theory of evolution provides a number of insights:

-it tells us how the species are related
-it tells us how the species and populations react to the changes in their environment

With this knowledge, the scientists can predict how the species will react to the potential changes and support the positive changes (provide a good environment for the animals for example)

Which of the following 9 objects is living or nonliving: bacteria, virus, moss, you, a lemon seed, the air, bread, lettuce and rocks. Apply each of the characteristics of life to each object in order to answer the question.

Answers

bacteria - living
virus - non living
moss - living
you - living
a lemon seed - living
The air - non living
bread - non living
lettuce - living
rocks - non living

Bacteria and Virus exhibits asexual reproduction and hence living.
Moss, humans and lettuce exhibit sexual reproduction and growth with in them occurs from the inside due to multiplication of cells.Hence, they are considered living too..
A lemon seed is a living thing because it exhibits growth due to multiplication of its cells and it participates in respiration also.
Bread is non-living as it is a man-made product and has no signs of life in it.
Air is non-living as its just a mixture of gases and gases possess no life with in!
Rocks are non-living as they are formed just by the accumulation of soil and mineral particles which are indeed non-living.

During lung inflation Multiple Choice surfactant is found in the pleural cavity. the lungs cling to the internal surface of the chest wall as it expands. the intrapleural pressure is higher than the intrapulmonary pressure. the lungs expand outward with the chest wall as it expands.

Answers

Inflation

Explanation:

During inflation, air moves in the lungs when the air pressure within the alveolar spaces falls below the atmospheric pressure

The forces that normally cause changes in volume of the chest and lungs arises not only from muscle contraction but from the elastic properties of both the lung and the chest

The force required to maintain inflation of the lung and to cause airflow is provided by the chest and diaphragm (the muscular partition between chest and abdomen), which are in turn stretched inward by the pull of the lungs

Hence during lung inflation, the lungs cling to the internal surface of the chest wall as it expands

Compare viruses to a definitely living organism, such as a giraffe, and a definitely non-living object, such as a rock. Do viruses have more in common with the living organism or the non-living object

Answers

Viruses have to adapt to environment in similar ways that and replicate like living organisms do, however viruses aren’t made out of cells and they infect cells of hosts.

According to Newton's Second Law of Motion, when an object is acted on by an unbalanced force, how will that object respond? A. It will accelerate. B. It will stop moving. C. It will decrease speed. D. It will increase velocity.

Answers

According to Newton's Second Law of Motion, when a force acing on the object is unbalanced, the object will accelerate. So, the correct option is (A).

What is Newton's Law?

1. Newton's first law of motion

This law is also called the law of inertia. This law states that an object at rest will remain at rest, and an object in motion will continue to move at a constant speed and in a straight line unless acted upon by an unbalanced force.

2. Newton's second law of motion

This law states that force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force which imposed on it. The force acting on object is directly proportional to the mass and acceleration.

F = m.a

Where, F- force

m - mass

a - acceleration

3. Newton's third law of motion

This law states that when two bodies interact with each other, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.

Above example is the explanation of second law of motion.

Thus, According to Newton's Second Law of Motion, when a force acing on the object is unbalanced, the object will accelerate. So, the correct option is (A).
