Positive feedback mechanisms are useful for which of the following situations?

A. Modulating a stimulus to stay within a defined range ·

B. Modulating a stimulus to move toward an endpoint

C. Amplifying a stimulus to move toward an endpoint

D. Amplifying a stimulus to stay within a defined range

Answers

Answer 1

Answer:

C. Amplifying a stimulus to move toward an endpoint

Explanation:

The mechanism of inputs and outputs are operated by biological systems. It is either it is caused by an event or it is causing a certain event. Feedback is very important in this system. Feedback loops are the paths in which a change to the system brings about an alarm that actually brings a certain result. In a positive feedback loop, the product of a reaction brings an increase in the reaction. This is carried out by amplifying effects of a product (stimulus) to move toward an endpoint.

Option C is the correct answer.

how could changing one mRNA codon change a protein?

Answers

Answer:

the outcome of a frame shift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of condons,or groups of three nucleotides. theses groups are called the reading frame.

Explanation:

hope that helps.:)

Changing one mRNA codon will change a protein because each protein

have their specific mRNA codons.

The mRNA codon are translated into a single amino acid during polypeptide

formation. Changing one mRNA codon will result in the formation of a

different type of protein.

The mRNA codon comprises of three base pairs and a change in an amino

acid such as Alanine which has a codon of GCA which when replaced by

GAC will form aspartic acid.

By genetic modification and evolutionary processes, biodiversity is increased and decreased by habitat loss, population reduction and extinction. The number and relative abundance of species present in a given biological organization is simply species diversity (population, ecosystem, Earth).

Answers

Answer:

Genetic Modification is a procedure to change the qualities of a plant, creature or miniature life form by moving a bit of DNA from one living being to an alternate living being. This is done through focused expulsion of the ideal qualities from the DNA of one living being and adding them to the next living being. This strategy has for instance been utilized to create growths and microorganisms that produce drugs.

Explanation:

Evolution is change in the heritable qualities of organic populaces over progressive ages. These attributes are the statements of qualities that are given from parent to posterity during generation. Various attributes will in general exist inside some random populace because of transformation, hereditary recombination and different wellsprings of hereditary variety. Evolution happens when transformative cycles, for example, regular choice (counting sexual choice) and hereditary float follow up on this variety, bringing about specific qualities getting more normal or uncommon inside a populace.

It is this cycle of development that has offered ascend to biodiversity at each degree of natural association, including the degrees of species, singular life forms and atoms.

Explanation:

Compound microscopes and dissecting microscopes are two types of light microscopes. This means that both types of microscope uses light as a source of view. However, they are used for different purposes despite this similarity.

- The compound microscope is used to view the internal features of a small specimen by looking through it. This is due to the high magnifying power of its objective lenses (40x - 1000x).

- On the other hand, dissecting microscopes are used only to view the surface of a large specimen owing to its low magnifying power. It can be used to view a three dimensional object.

What effect do glaciers have on plant life?

Glaciers bring quantities of minerals that choke plant life as the water runs off melting ice.
Glaciers has no effect on plant life other than helping distribute necessary water.
Glacial flooding is destructive to plant life as silt builds in rivers.

Answers

Answer:

Glaciers bring quantities of minerals beneficial to plants as the water runs off melting ice.

Explanation:

Glaciers are natural reservoirs of water and minerals that may persist to dry conditions during the summer season. Ice melting provides water and minerals during the warm season, which is therefore critical for plants living in dry summer environments. Moreover, it is well-known that the 'melt-water' (i.e., water released by the melting of glacial ice) also affects downstream stream water temperatures, creating a microhabitat that may be beneficial to the life of plant species.

In the game, two simulated players each start out with an equal number of coins. In each round, each player chooses to spend either 1, 2, or 3 coins. Coins are then awarded to each player according to the following rules.Same rule: If both players spend the same number of coins, player 2 gains 1 coin.Off-by-one rule: If the players do not spend the same number of coins and the positive difference between the number of coins spent by the two players is 1, player 2 is awarded 1 coin.Off-by-two rule: If the players do not spend the same number of coins and the positive difference between the number of coins spent by the two players is 2, player 1 is awarded 2 coins.The game ends when the specified number of rounds have been played or when a players coin count is less than 3 at the end of a round.The CoinGame class is shown below. You will write two methods in the CoinGame class.public class CoinGame{private int startingCoins; // starting number of coinsprivate int maxRounds; // maximum number of rounds playedpublic CoinGame(int s, int r){startingCoins = s;maxRounds = r;}/** Returns the number of coins (1, 2, or 3) that player 1 will spend.*/public int getPlayer1Move(){/* implementation not shown. */}/** Returns the number of coins (1, 2, or 3) that player 2 will spend, as described in part (a).*/public int getPlayer2Move(int round){/* to be implemented in part (a) */}/** Plays a simulated game between two players, as described in part (b).*/public void playGame(){/* to be implemented in part (b) */}}In the simulation, player 2 will always play according to the same strategy. The number of coins player 2 spends is based on what round it is, as described below.(a) You will write method getPlayer2Move, which returns the number of coins that player 2 will spend in a given round of the game. In the first round of the game, the parameter round has the value 1, in the second round of the game, it has the value 2, and so on. The method returns 1, 2, or 3 based on the following rules.If round is divisible by 3, then return 3.If round is not divisible by 3 but is divisible by 2, then return 2.If round is not divisible by 3 and is not divisible by 2, then return 1.Complete method getPlayer2Move below by assigning the correct value to result to be returned./** Returns the number of coins (1, 2, or 3) that player 2 will spend, as described in part (a).*/public int getPlayer2Move(int round){int result; return result;}Write the method playGame, which simulates a game between player 1 and player 2, based on the rules and example shown at the beginning of the question. Both player 1 and player 2 start the game with startingCoins coins. Computer player 1 spends 1, 2, or 3 coins based on the value returned by the method getPlayer1Move(). Computer player 2 spends 1, 2, or 3 coins based on the value returned by the method getPlayer2Move().The game ends when maxRounds rounds have been played or when a players coin count is less than 3 at the end of a round.At the end of the game, the winner is determined according to the following rules.If both players have the same number of coins at the end of the game, the method prints "tie game".If player 1 has more coins than player 2, the method prints "player 1 wins".If player 2 has more coins than player 1, the method prints "player 2 wins".(b) Assume that getPlayer2Move works as specified, regardless of what you wrote in part (a) .
