y short repeats. b) Moderately repetitive DNA contains transposable elements and genes that are expressed in abundance and thus have many copies. c) Moderately repetitive DNA contains retro elements, such as the Alu sequence. d) Moderately repetitive DNA contains unique sequences, such as genes found in one or a few copies. e) Highly repetitive DNA contains transposable elements and genes that are expressed in abundance and thus have many copies.

Answer:

c) Moderately repetitive DNA contains retro elements, such as the Alu sequence.

Explanation:

The genetic material (DNA) has been proven to contain segments or sequences that are non-coding regions i.e. do not encode proteins. These non-coding sequences can either be repeated in the genome (repetitive) or not (non-repititive). The repetitive DNA sequences can consist of short sequences that repeat themselves enormous amount of times in the genome. This repetitive DNA sequence is said to be HIGHLY repetitive.

Another one can contain long nucleotide sequences scattered in the genome. They do not repeat as often as the highly repetitive sequences. They contain retro elements like Alu sequences and transposons. These sequence is said to be MODERATELY repetitive.

The non-repititive sequences are the part of the DNA that encodes a protein. They are called unique sequences because they occur in only one or few copies in the genome.

Answer:

b) Moderately repetitive DNA contains transposable elements and genes that are expressed in abundance and thus have many copies.

Explanation:

Moderately repetitive DNA usually has longer sequence of  bases, with many  nucleotide distributions. Thus if the sequence of bases expressed encoded genes, then the longer sequence will ensure many copies of genes of varied types of proteins. Therefore  the more moderately repetitive the DNA the more genes are expressed, and  the more rooms for variation, and therefore many  gene copies produced.

Which climate is warm, wet, and located on the edges of the tropics?
Lena [83]
The correct answer is c. Temperate marine.
Temperate continental their climate is wet, warm, and located on the edges of tropics. They are found in the continents in the northern hemisphere. They are not located near oceans where temperatures are moderate. They are also referred to as microthermal climates. They are located away from oceans that is why they do experience extreme temperatures. They have both summers which are warm and humid and winters which are blustery winds and snowstorms.

To survive, an organism must be able to maintain stable internal conditions in a changing environment. This process is called ho
Reptile [31]

Answer:

1. Initial air temperature: 0 °C (32 °F)

2. Initial body temperature: 37 °C (99 °F)

3. The expected effect of different factors on body temperature are:

   A. Raising air temperature: Increase

   B. Lowering air temperature: Decrease

   C. Adding clothing: Increase

   D. Exercising: Increase

Explanation:

The question is incomplete, it is necessary to look for a software related to this homework.

<u>Homeostasis is a property of organisms that consists in their capacity to maintain a stable internal condition by compensating for changes in their environment</u> through the regulated exchange of matter and energy with the exterior. It is a a dynamic equilibrium controlled by a mechanism of feedback that constitute the self-regulating mechanisms. Examples of homeostasis are temperature regulation and the balance between acidity and alkalinity (pH)

The Human Homeostasis Gizmo™ is a software that allows you to explore  how the human body stays at a nearly constant  temperature in different conditions.  To use it, you have to set the air temperature at 0 °C (32 °F) and the body temperature at 37 °C (99 °F), and click Play. After a simulation of 1 hour, then click Pause and gather the information. Then, do the same cprocedure  to test the effect of other factors and Click Reset between each trial. To determine the effect of different factors on body temperature, you have to compare the  final body temperature to the final body temperature while  there is no specific movement or change.

Then:

1. Initial air temperature: 0 °C (32 °F)

2. Initial body temperature: 37 °C (99 °F)

3. The expected effect of different factors on body temperature are:

   A. Raising air temperature: Increase

   B. Lowering air temperature: Decrease

   C. Adding clothing: Increase

   D. Exercising: Increase

This is for a logical reason, anything you do to heat it or generate heat, will increase the temperature. And anything you do to generate cold, will lower the temperature.

The effect of different factors on body temperature according to Gizmo:

   A. Raising air temperature: Increase

   B. Lowering air temperature: Decrease

   C. Click Add to a sweatshirt, hat, pants, and  parka. Then, adding clothing:

   Maintained

   D. Set the Exercise level to 70%, then exercising: Increase

When the temperature increases, it is because you are able to record the results from the software and you see temperature goes from 99 °F to 100 °F. When the temperature decreases. it is because it goes from 99 °F to 97 °F. When it is maintained, there is no change.

Half of the moon is always lit except during an eclipse.<br><br> True or false?
olga nikolaevna [1]

Answer:

Half of the Moon's surface is always illuminated by direct sunlight, except during lunar eclipses when Earth casts its shadow on the Moon. Just how much of that light we can see from Earth varies every day, and we refer to this as a Moon phase.
