What will happen if we put a Rhoeo leaf in plain water?

Oksanka [162]

<span>If we put a Rhoeo leaf in plain water, the water concentration of the leaf cells will be higher than that of the plain water. The aim is to balance water concentration on the inside and outside of the organism. So, the water will exit the leaf cells, which will consequently shrink in size. The most of the cells will shrink in size, causing the leaf to shrink, too.</span>

Adaptive immunity comprises two branches: humoral immunity and cellular immunity. What are the characteristics of each of the tw

kotegsom [21]

Answer:

Adaptive or acquired immunity is that we acquire throughout our lives through vaccines (active), breast milk (passive) or injection of specific artificial or natural antibodies to a certain pathogen (passive).

The two great arms of this immunity are the humoral and the cellular.

The humoral refers to the cytokines and immunomodulatory molecules that are responsible for transmitting fundamental messages between defense cells in order to coordinate the destruction of the pathogen between them.

Instead, cellular immunity speaks about cell lineage such as b, t, tcd4 lymphocytes, natural killers, plasmacytes, etc.

It can be said that the humoral factor is the one that coordinates the pathways and the relationships between the cells of the acquired immunity, both are important because the two need each other for adaptive immunity to work.

Explanation:

Examples of the humoral factor: pro and anti inflammatory cytokines, interleukins, complement chain, antibodies, TNF alpha, beta, etc.

Examples of cellular factor: plasmacyst, b lymphocyte, t lymphocyte, NT lymphocyte

Inga [223]

Answer:

I would write "terrestrial/lives on land during all life stages" between the frog and pigeon branches.

Explanation:

Jaw evolution has started with fish, so i'd place that before the perch, evolution of four limbs is next and I would plate it between the perch and the frog. Evolution of an egg has ensured that organisms remain terrestrial during all stages of life and don't need to rely on water to lay their eggs. So I would place that between the frog and the pigeon. True mammary glands and true hair, as we know it formed on mammals so i'd place that between the pigeon and the rats (although synapsids evolved similar structures long before birds even existed). And lastly, I would place "walking on two legs" between rats and human branches. Because our ancestors evolved bipedalism relatively late.
