Advocard [28]

Megasporangium tissue gives rise to the female gametophyte.

<h3>What is the name of the diploid tissue that gives rise to the female gametophyte?</h3>

Three of the four haploid megaspores worsen into antipodal cells interior the female gametophyte.
The central cell of the female gametophyte contains two cores that when fertilized gotten to be the endosperm.
Megasporogenesis alludes to the advancement of megaspores from the megasporocyte, the cell that experiences meiosis.
Meiosis of the megasporocyte core comes about within the arrangement of four haploid megaspore cores.
In most taxa, meiosis is taken after by cytokinesis, coming about in four megaspore cells.
This design is named monosporic megasporogene - sis; since of the four megaspores delivered, as it were one of them contributes to the female gametophyte

Answer: The non-vascular plant group are

A) Chlorophytes

B) Charophytes

C) Bryophytes

Explanation:

Charophytes, Chlorophytes and

Bryophytes are those plants having multicellular body and doesn't have a vascular bundle i. e. xylum and phloem. In vascular plants, xylum ia is responsible for the transportation of water and phloem is responsible for the transportation of food materials from one part to another. These bundles are absent in Chlorophytes, Charophytes and Bryophytes.

<u><em>Boreal forest </em></u><em> is a large amount of carbon is being taken in by Biome</em>

Answer: C. Boreal forest

Explanation:

BOREAS is the investigation completed in the boreal woodland at Canada that spotlights on improving our comprehension of the radiant energy, heat, water, carbon dioxide and gases between the boreal forest and the environment.

An essential goal of BOREAS was to gather the information expected to improve the models of computer simulation of the significant procedures controlling these exchanges with the goal that researchers can envision the impacts of worldwide change on the biome.

Which statement explains the difference between multiple alleles and polygenic inheritance?

sergeinik [125]

Answer:

B. Multiple allele means more than two forms of the same gene in the population and polygenic inheritance means more than one gene contributes to the phenotype of a trait.

Explanation:

Multiple alleles are an alternative form of allies and can occupy the same gene ad only two of them can be found in the same organism. Such as the ABO blood group.

A polygenic or a multiple gene inheritance is a hypothetical gene that s often difficult to characterize and traits control a multiple of genetic loci, they are relatively small and interchangeable.

What term refers to how fast blood traveled from its source? _________ refers to how fast blood traveled from its source to wher

muminat

Answer:

Impact.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

In Science, the study of blood is generally referred to as serology.

Impact refers to how fast blood traveled from its source to where it landed.

This ultimately implies that, an impact is a measure of the rate at which blood travels from its source to where it lands. The four (4) phases of impact includes;

I. Displacement.

II. Retraction.

III. Contact and collapse.

IV. Dispersion.

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

Generally, the right atrioventricular valve (AV) is also referred to as the tricuspid valve and is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
