It is a winter day in Florida, and the temperature is 40°F in the morning. While you are walking to class, your body uses a nega

tive feedback loop in order to shiver and maintain your internal body temperature at 98.6°F. After class, the temperature outside has increased to 80°F and you begin to sweat since you are still wearing your winter clothes. Is the process of sweating in order to cool down and maintain an internal body temperature of 98.6°F an example of a positive or negative feedback loop?

Answer:

negative feedback

Explanation:

The negative feedback system is the most common in the body, being considered by many authors the primary mechanism for the maintenance of homeostasis. It causes a negative change from the initial change, that is, a stimulus contrary to the one that led to the imbalance. In the case of the above question, when the ambient temperature increased, your body began to sweat to lower the temperature, that is, your body is trying to make a stimulus contrary to what is happening in the environment, so we can state that your body is going through a negative feedback system.

Answer:

The three processes from left to right are:

<u>Replication</u>   DNA  <u>Trancription</u>  RNA  <u>Translation</u> Protein

Explanation:

The process in question in the diagram is called the central dogma of life which describes the flow of genetic information from DNA to RNA to Protein. The three processes involved are:

  1. DNA Replication
  2. Transcription
  3. Translation

DNA Replication:

DNA replication is the process by which DNA makes a copy of itself. Replication of DNA is semi-conservative. this means that each new helix is a combination of an old (parent) strands and a new (daughter strand). The parental strand is used as a template to generate a complementary daughter strand.

Transcription:

Transcription is the formation of an RNA transcript of the DNA template. This process yields a mRNA that is further used as a code to manufacture proteins in the process of translation.

Translation:

Translation decodes the mRNA formed in transcription to generate proteins with specific amino acid sequence.

The image below shows people using sandbags as a means to contain a rapidly rising river. Which process of soil erosion is being
Brrunno [24]
<h2><u>Answer: </u></h2>

<u>Erosion:</u> is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.  A similar process, weathering, breaks down or dissolves rock, but does not involve movement.Erosion is the opposite of deposition, the geological process in which earthen materials are deposited, or built up, on a landform. Most erosion is performed by liquid water, wind, or ice .  Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.

<u>Public domains:</u>VegetationThe simplest and most natural way toprevent erosion is through planting vegetation. Plants establish root systems, which stabilizes soiland prevents soil erosion. Geotextiles: Using geotextiles is an effective method because it also stabilizes soi .

<u> People placing sandbags along the shore of a river:</u>

The use of sandbags is a simple, but effective way to prevent or reduce floodwater damage. Properly filled and placed sandbags can act as a barrier to divert moving water around, instead of through, buildings. ... Tied sandbags are generally easier to handle and stockpile.

You are attempting to see if a suspect is associated with a crime. The only evidence you have is a tiny drop of blood from the c
kykrilka [37]

Answer:

There are no options in this question but generally a sample of DNA can be increased;

By using Polymerase Chain Reaction (PCR) technique.

Explanation:

This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.

In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.

Which organelle is responsible for digesting materials and cleaning up the cell of wastes?
nlexa [21]

Answer:

Lysosomes

Explanation:

  • Lysosome are among the organelles in a eukaryotic cell. Lysosomes are formed by the golgi bodies or the golgi apparatus.
  • <em><u>The role of lysosomes is to digest and destroy old and worn out organelles together with cellular wastes. In other words Lysosomes break down food molecules, waste products, and old worn out cells or organelles.</u></em>
  • They contain powerful lytic enzymes and and acids which help in the digestion and recycling of cellular materials.
