Answer:

physical process

Explanation:

Assuming that there are no latency mechanisms that prevent germination, several factors are required for the embryo contained in the seed to restart its development.

Water Absorption

Embibition: It is a special case of a <u>physical phenomenon</u> called diffusion, and as such, there is a diffusion gradient. It is characterized by an increase in volume of the substance or body that embeds and is closely related to the properties of colloidal materials. The colloidal particles in the seed form a moderately rigid miscelar network, in which electric charges of opposite signs are oriented in a defined manner. When water penetrates the seed, one fraction occupies the free spaces and another chemically joins the substances of which the seeds are composed. The volume of the seeds increases with the embibition, but the final volume of the system (seed + water) is smaller than the sum of the initial individual volumes of seeds and water; This contraction of the system is proof of the occupation of the free spaces within the seed and the absorption of water in the colloidal matrix.

The embibition rate is affected by several factors that can determine the germination response of the seeds.

<h2>Apical complex</h2>

Explanation:

A group of cytoskeletal structures and related layer limited organelles found at the foremost finish of grown-up commit intracellular protozoan parasites in the phylum Apicomplexa. The apical complex is engaged with connection to and infiltration of the host cell and in parasite multiplication.
Apicomplexans : Ciliates are pretty cool, but they're not the only group of alveolates out there. Next, we've got the apicomplexans. This group is characterized by an asymmetrical collection of alveoli at one end of the cell, which is called the apical complex.
the apical complex has shaped the way it is because it helps the cell latch onto and infects other cells.That's right, apicomplexans are parasitic. There are 4,000 known species of apicomplexans, all of them parasitic, and some of them pretty nasty.

Which of the following describes a function of the endoplasmic rectum within a cell

Pachacha [2.7K]

Explanation:

Endoplasmic reticulum is one of the cell organelles found in the cytoplasm of the cell. It is an important cell structure. It is made up of folded membranes.

In the endoplasmic reticulum protein is synthesized.
It helps in the transport of protein molecules to the golgi apparatus.
Protein is usually folded in the endoplasmic reticulum.

Is biotechnology always associated with genetic engineering? Explain your answer.

prohojiy [21]

Answer:

Yes, the biotechnology are associated with the genetic engineering as, the genetic engineering are the direct modification or manipulation of the organism which are using the biotechnology.

Basically, it the set of technologies which are used to modify the genetic cells including the transferring of the genes across the boundary to produced the organism. And with the help of biotechnology, new DNA are obtain by copy the genetic material by using the methods of DNA.

What does cellular respiration have to do with metabolic processes?

bixtya [17]

Answer:

Metabolism refers to all the chemical reactions in the body, including those that use oxygen and create carbon dioxide. Oxygen and carbon dioxide, therefore, are involved in both respiration and metabolism. Metabolic reactions are sometimes referred to as cellular respiration, which can cause confusion.
