* Apply Concepts A particular plants diploid number of chromosomes is 50. Describe the number of chromosomes in one of the plant
Gnoma [55]

Chromosomes have hereditary function that are capable of self-duplication and they have thread-like structures seen inside the nucleus of plant and animal. In plants, they go through a cycle called alteration of generation that has multicellular stages. One is sporophyte that is a diploid, and the other is gametophyte with a haploid.

Moreover, spores are produce through meiosis so it go through a process of chromosome reduction in order to create a haploid spores. While, gametes undergo mitosis and the structure is already a haploid, which means that the number of chromosomes will not change in order to produce haploid. In this case, the plant have both spores and gametes and the similarities is that, they are both singles celled and a haploid. Therefore, the number of the chromosome in the gametophyte generation is also 32.

In what direction does blood flow through the heart? a) from ventricles to atria b) from a region of high pressure to a region o
Sauron [17]

Answer:

b) from a region of high pressure to a region of low pressure

Explanation:

Blood flow is measured in blood volume per unit time. It is the movement of blood through an organ, tissue or vessel. It is initiated when ventricles in heart contract leading to its ejection at high pressure. Major arteries receive this blood and they further transport it at high pressure to smaller arteries, arterioles and capillaries. Hence arteries have thick walls to withstand this pressure. The pressure decreases when blood reaches to veins hence their walls are not that thick.  Hence, blood flows from a region of high pressure to a region of low pressure.

What is the study of fish known as in biology?​
klio [65]

Answer:

The study of fish is called Ichthyology.

Explanation:

Fish specimens are identified in the field by ichthyologists. Ichthyology is the field of study that deals with fishes. Taxonomy (classification and the description of new species) and biogeography are the two main areas of focus for museum ichthyologists (patterns of distribution).

Ichthyology is the field of study that deals with fishes. Taxonomy (classification and the description of new species) and biogeography are the two main areas of focus for museum ichthyologists (patterns of distribution). Large reference collections of preserved specimens are kept in museums as a permanent resource for present-day researchers as well as for future ones.
