Answer:

Exergonic reaction

Explanation:

A chemical reaction which is associated with a release of energy and thus, is associated with a negative free energy change is said to be an exergonic reaction.

An exergonic reaction owing to the negative free energy change is a spontaneous reaction.

The energy that is released in the exergonic reaction is usually observed in the form of heat and light.

The energy is released due to the breaking of the chemical bonds.

Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.

Which Mimulus species would you categorize as mainly asexual reproducers? Why? A. M. rupestris and M. eastwoodiae; they put more

nekit [7.7K]

Answer: C. M. rupestris, M. eastwoodiae, and M. nelsonii; they put more energy into making rooted branches than they put into making nectar and seeds.

Explanation:

In asexual mode of reproduction the plant does not produce gametes. The plant reproduce through vegetative propagation or spore formation. The plant does not produce nectar as no flowers are produced to attract the pollinators.

In sexual mode of reproduction the plant will develop the gametes and flowers will produce the nectar to attract the pollinators.

Thus on the basis of above explaination, C is the correct option. As the plants will invest more energy in making roots which are the organs for vegetative propagation a process of asexual reproduction.

As blood pressure increases and the hearts is working harder the most vulnerable arteries area? Located near the heart, because

KIM [24]

As blood pressure increases and the hearts is working harder the most vulnerable arteries area are those <u>Located near the heart, because they are absorbing the most shock.</u>

<u></u>

Explanation:

When the heart pumps blood, the highest pressure is felt close to the heart. This is why the aorta, the artery that carries blood away from the heart is made up of thick walls to withstand this pressure, otherwise, these vessels would rupture. Away from the heart, this pressure lessens, and the blood vessels are not so thick-walled.

Explain why it is important for dying cells to be properly removed

victus00 [196]

Cells within the body are properly arranged and their production uses up resources of the body. For example, red blood cells use iron while being produced. The body must dispose of cell properly to maintain the orderly arrangement of cells; for example, if dead skin cells were not removed, we would lose feeling in our skin due to the layer of dead cells. Moreover, the body must work to minimize wastage. This is why some of the iron from red blood cells is removed and reused.

What are the two theories that are combined in the synthetic theory of evolution?

Alika [10]

The Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.

<h3>Synthetic theory of Evolution </h3>

The synthetic theory of evolution states that evolution are the changes occurring in the allele frequencies within the populations.

The theory explains that changes in the genes of organism are what causes the evolution of organism.

The Darwinian theory of Evolution states that organisms better adapted to their environment survive and give birth to offspring suited for their environment.

The Mendelian theory of genetics states that the combination and resassortment of genes are responsiblefor character inheritance.

Therefore, the Modern Synthetic Theory of Evolution combines the Darwinian theory of evolution with Mendel's genetic theory.
