Explanation:

Do environmental or genetic factors affect growth of organisms most?

Answers

Answer:

Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. The environment in which an organism lives plays an important role in modifying the rate and extent of growth. Environmental factors may be either physical (e.g., temperature, radiant energy, and atmospheric pressure) or chemical. Organisms and the cells of which they are composed are extremely sensitive to temperature changes; as the temperature decreases, the biochemical reactions necessary for life occur more slowly. A lowering of the temperature by 10° C (18° F) slows metabolism at least twofold and often more.

I copied this stuff from a bunch of different biology websites. It doesn't answer your exact question but I would have to say based on what I typed here it would be the environment that affects the growth of an organism more.

What is the main difference between active and passive sonar

Answers

Answer:

There are two kinds of sonar: One is passive sonar, and the other is active sonar. For passive sonar, we don't send sound waves but just receive them. By listening to these special sound waves, animals that communicate with these particular sound waves can be detected. By listening to the sound waves from engines of submarines or ships, we can locate them.

Also, other things that vibrates can be detected by passive sonar. Many threats on the sea are usually detected by passive sonar this way. Since passive sonar does not transmit any thing to the environment, it does no harm to other animals. Active sonar is a little different.

Besides having a receiver, active sonar also transmits sound waves. Active sonar works by transmiting particular sound pulse and measuring the length of time for the sound to be reflected back, then devide the time by 2 to get the time it takes for the sound pulse to reach the object

B. Channel and carrier proteins are both types of facilitated transport.

C. Channel and carrier proteins can only move substances in one direction either into the cell or out of the cell.

D. Channel and carrier proteins always move substances from the side of the membrane with the highest concentration to the side with the lowest concentration.

Answers

Answer:

a

Explanation:

A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.

Channel and carrier proteins are both types of facilitated transport.

Facilitated diffusion is one of the ways of transporting molecules and is characterized by the use of proteins that are inserted in the plasma membrane, such as ion channels and carriers or permeases.

Ions, amino acids and monosaccharides, among many other molecules, cannot cross the plasma membrane, because they are polar or are very large in size.

So, for the cell to obtain or eliminate these substances, the presence of transporter proteins is necessary.

This diffusion is a type of passive transport, because it takes advantage of the concentration gradient of the molecules and does not waste energy.

Ion channels are integral tunnel-shaped proteins, selective for one, two, or three ions.

When a channel opens, ions flow under two principles: the concentration gradient and the electrochemical gradient.

Consequently, when an ion channel opens, the potential difference between the two compartments is altered.

Transmembrane proteins mediate the transport of molecules such as bicarbonate or large, polar, uncharged molecules such as glucose.

The transport through these proteins occurs in favor of the concentration gradient, and by a reversible conformational change of the proteins that allows the translocation of the molecule to the other side of the membrane.

This type of transport is always without energy expenditure and in favor of the electrochemical gradient, it occurs in the following way:

Uniport, a single molecule translocates in only one direction.

Simporte, two molecules that translocate in the same direction.

Therefore, we can conclude that channel and carrier proteins are both types of facilitated transport.

b) The reduced coenzyme bound to PDH is reoxidized using electrons from FAD.
c) An acetyl group is added to a coenzyme bound to PDH, forming acetyl-dihydrolipoamide.
d) The acetyl group is transferred to CoA, forming acetyl-CoA.
e) Electrons from FADH2 are transferred to NAD+ forming NADH and H+.

Answers

Answer:

The correct order is:        

1.- pyruvate and thiamine pyrophosphate react form hydroxyethyl-TPP, CO2 is released

2.- an acetyl group is added to a coenzyme bound to PDH, forming acetyl-dihydrolipoamide

3.- the acetyl group is transferred to CoA, forming acetyl-CoA

4.- the reduced coenzyme bound to PDH is reoxidized using electrons from FAD

5.- electrons from FADH2 are transferred to NAD+ forming NADH and H+

Explanation:

Pyruvate reacts with thiamine pyrophosphate (TPP) on the complex enzyme pyruvate dehydrogenase (E1). This process cleaves CO2 and generates acetaldehyde bound to TPP or hydroxyethylamine. E2 is Dihydrolipoyl-transacetylase and has Lipoamide attached. In the transfer from E1 to E2, the hydroxyethyl is oxidized to acetyl, at the same time that the disulfide bridge of the lipoamide is reduced to dihydro-lipoamide, although as this is acetylated, the product is acetyl-dihydrolipoamide. Acetyl group of acetyl-lipoamide (thio-acyl bond) is transferred to CoA-SH, to form Acetyl-S-CoA (thio-acyl bond).Acetyl-CoA is released into the mitonchondrial matrix. Lipoamide is reduced as Dihydro-lipoamide. The last reaction is catalyzed by dihydrolipoyl dehydrogenase, where it is reestablished in the disulfide bond of lipoamide to make it reactive again. For this, FAD is used as an intermediate, which is reduced to FADH2 and oxidizes the sulfides (which are then linked again). Finally, FADH2 reacts with NAD, which is reduced to NADH and H+ released, restoring FAD for a new reaction.

Answers

Answer:

1. Homeostasis

2. Organ system

3.The bones of the skeletal system serve to protect the body's organs, support the weight of the body, and give the body shape. The muscles of the muscular system attach to these bones, pulling on them to allow for movement of the body.

4.The nervous and endocrine systems are two forms of communication system in the human body that integrate, coordinate and respond to sensory information which is received by the human body from its surroundings

5.The skin functions by protecting the body from basic elements of nature such as water, UV sunlight and wind. ... However, skin in integumentary system acts by maintaining the internal conditions that is required by the body while it is excretory system because it secretes a fluid waste called sweat or perspiration.

6.In order to survive, cells must satisfy some basic needs such as oxygen, water, nutrients, waste removal, and maintaining of homeostasis. Oxygen and nutrients are necessary for different processes inside the cell. For instance, cellular respiration uses glucose and oxygen to form energy in the form of ATP.Water is important for different chemical reactions, as well. Also, the result of different processes, waste is produced and it is important to remove it from the cell. Finally, it is important that cell and whole body conditions do not vary so much and that homeostasis is maintained.

7.Ribosomes provide another good example of structure determining function. These small cellular components are made of protein and ribosomal RNA (rRNA). Their main function is to translate messenger RNA, or mRNA, into strings of amino acids called proteins.

8.  the body is not in homeostasis from 7 to 10 hours. Explanation: The given graph shows homeostasis in terms of body temperature. The normal body temperature, that is 37 degrees C is maintained from 1 to around 6:45 hours.

9.There are several reasons why the body temperature falls continuously just like when you are exposed to an extreme cold weather or wearing wet clothing for a long time. This abnormality state of the body temperature can lead into some potential diseases and disorders like infection, insomnia, stress and sepsis

10.Sweating also hydrates your skin and maintains the balance of electrolytes in your body. The fluid you sweat comprises mainly salt and water. Excessive sweating can cause dehydration since you lose a large amount of water. The technical term for excessive sweating is hyperhidrosis.

Do you think an advanced civilizations may exist in the universe? Why or why not?

Answers

Answer:

Many other planets throughout the universe probably hosted intelligent life long before Earth did, a new study suggests.

The probability of a civilization developing on a potentially habitable alien planet would have to be less than one in 10 billion trillion — or one part in 10 to the 22nd power — for humanity to be the first technologically advanced species the cosmos has ever known, according to the study.

"To me, this implies that other intelligent, technology-producing species very likely have evolved before us," said lead author Adam Frank, a professor of physics and astronomy at the University of Rochester in New York. [13 Ways to Hunt Intelligent Alien Life]

In 1961, astronomer Frank Drake devised a formula to estimate the number of extraterrestrial civilizations that may exist today in the Milky Way.

Adam Frank and co-author Woodruff Sullivan of the University of Washington were interested in the odds that intelligent aliens have ever existed anywhere in the universe. So they tweaked the famous Drake equation, coming up with an "archaeological version" that doesn't take into account how long alien civilizations may last.

Frank and Sullivan also incorporated observations from NASA's Kepler space telescope and other instruments, which suggest that about 20 percent of all stars host planets in the life-friendly, "habitable zone," where liquid water could exist on a world's surface.

Which of the following is conical movement in which the distal end of a structure moves in a circle and the proximal end remains relatively fixed?
A. Protraction
B. Rotation
C. Circumduction
D. Retraction

Answers

Answer:

The correct answer is OPTION C (Circumduction)

Explanation:

Circumduction is motions without clear opposites of the part of the body, an example is rotating the hand from the wrist. The answer is circumduction because this type of movement ensures the distal end of a bone moves in a circle while the proximal end remains relatively stable is particularly found in bones where the movements of the joints are opposite to each other example is the ball and socket joint movement. For circumduction to take place, the degree of distance between two bones of the body has to be decreased and sometimes straightened to increase the level of movement or motion produced, there must be a movement towards the middle of the body and sometimes joint movement away from the middle of the body. All these movements are in order.
