Answer:

Explanation:

the process of transcription is defined as a process by which cells are able to allow for expression of their genes. this involves how DNA is read and written into RNA (mainly messenger RNA). mRNA production then guides the synthesis of various proteins. the process of transcription occurs in three stages which include initiation, elongation and termination. when certain signals interact with the promoter of a gene, transcription is initiated allowing for some regions of the DNA to be transcribed in the 5 to 3' direction. such that the newly synthesized strand of mRNA is complementary to the non coding sequence. Controlling the production of mRNA in the nucleus allows the regulation of gene expression.

What are the mechanisms by which aneuploidy and polyploidy are caused? What are the mechanisms by which aneuploidy and polyploid
sleet_krkn [62]

The correct answer is:

The principal cause of aneuploidy is chromosome nondisjunction during mitosis or meiosis. Polyploidy in nature can result either from the duplication of euploid chromosome sets from a single species or from the combining of chromosome sets from different species.  

Aneuploidy is a phenomenon when there is the presence of an abnormal number of chromosomes in a cell (an extra or missing chromosome). Usually it appears as a result of improper cell division (chromosomes don’t separate) and it can cause many genetic disorders.

Polyploidy refers to a state when there are more than two sets of chromosomes (one from mother one from father). Triploid (three sets of chromosomes) and tetraploid (four sets of chromosomes) chromosomes are examples of polyploidy. This phenomenon is most common in plants.

Alexandra [31]

Answer:

food web

Explanation:

Food web is an interconnection and assimilation of different good chains. Many food chains are interlinked a hence a food web is created. This represents what is eaten by which organism. The diagram that Ari had drawn is a diagram of a food chain. The grass is the primary source of food in the food web. Rabbit, Mouse, and grasshopper are the animals that eat the grass. The grasshopper is eaten by a shrew and a mouse. The rabbit and shrew are then eaten by the fox. A mouse is eaten by a snake and a fox. This is the diagrammatic representation of a food web.

Irina18 [472]
A CNA, certified nursing assistant, can administer medication to patients. BUT this duty is subject to the level of experience and training of the CNA as well as the regulation of the state.

CNAs basically assist in the day-to-day care of patients like:
1) bathe and dressing
2) serving meals and helping them eat
3) taking their vital signs
4) and other basic necessities to ensure that the patient is comfortable and well cared for.
