How does the color adaptation help fish residing in the coral reefs?

Answers

Answer:

Fish found in coral reefs also have bright coloring to help with mating or camouflage. Due to the wide variety of prey found in coral reefs, the fish have developed a generalized feeding structure to take advantage of the biodiversity. Lastly sessile animals, such as coral, have adapted toxins to keep away predators.

Explanation:

Answer:

Many fish have color patterns that help them blend in with their environment. This may allow the fish to avoid being seen by a predator. Some fish, such as the flat fishes (Pleuronectiforms) , can change their skin coloration to match the surrounding habitat. Fish can also have disruptive markings to hide body parts

Los insectos polinizadores son especies clave en muchas comunidades que interacción interespecífica se da entre estos insectos??

Answers

Answer:

Competencia interespecífica

Explanation:

Los polinizadores son organismos esenciales para el equilibrio de las comunidades silvestres y el mantenimiento de la biodiversidad existente en el planeta. Los insectos (especialmente las abejas) representan el grupo de polinizadores más importantes, estos organismos consumen el néctar como alimento y simultáneamente son utilizados por plantas para reproducirse mediante el trasporte del polen de una flor a otra. Los insectos polinizadores usualmente visitan muchos diferentes tipos de plantas y, a su vez, estas plantas son polinizadas por diferentes grupos de insectos polinizadores. Como consecuencia de esto último, entre polinizadores se establece una competencia interespecífica por un recurso (es decir, el polen) el cual a priori podría considerarse limitado. Sin embargo, ha sido demostrado que las redes e interacciones entre plantas y polinizadores están organizadas de tal modo que la competencia interespecífica entre polinizadores se encuentra reducida drásticamente, siendo incluso beneficiosas para las especies que la componen. Estos resultados se encuentran soportados por el análisis de información a campo la cual demuestra como redes entre polinizadores y plantas son similares en diferentes ecosistemas/continentes y también porque cuando tales conexiones gozan de buena salud se observa un aumento de la biodiversidad en las comunidades ecológicas.

Answers

Suppose you coated the leaves of a plant with petroleum jelly. How would the plant's rate of transpiration be affected?​

Answers

Answer:

The rate of transpiration would decrease

Explanation:

the petroleum jelly would block the stomata of the leaves resulting in decreased transpiration rates

Petroleum jelly would inhibit the loss of moisture out of the stomata cells. Therefore, the rate of transpiration would be decreased.

What is transpiration?

Transpiration exists the procedure of water movement via a plant and its evaporation from aerial parts, such as leaves, stems, and flowers. Water exists essential for plants but only a small amount of water brought up by the roots is utilized for growth and metabolism. The remaining 97–99.5% exists lost by transpiration. An example of transpiration exists when a plant absorbs water in its roots.

Hence, Petroleum jelly would inhibit the loss of moisture out of the stomata cells. Therefore, the rate of transpiration would be decreased.

For this exercise, you will complete the TicTacToe Board that we started in the 2D Arrays Lesson.We will add a couple of methods to the TicTacToe class.To track whose turn it is, we will use a counter turn. This is already declared as a private instance variable.Create a getTurn method that returns the value of turn.Other methods to implement:printBoard()- This method should print the TicTacToe array onto the console. The board should include numbers that can help the user figure out which row and which column they are viewing at any given time. Sample output for this would be: 0 1 20 - - - 1 - - - 2 - - - pickLocation(int row, int col)- This method returns a boolean value that determines if the spot a user picks to put their piece is valid. A valid space is one where the row and column are within the size of the board, and there are no X or O values currently present.takeTurn(int row, int col)- This method adds an X or O to the array at position row,col depending on whose turn it is. If its an even turn, X should be added to the array, if its odd, O should be added. It also adds one to the value of turn.checkWin()- This method returns a boolean that determines if a user has won the game. This method uses three methods to make that check:checkCol- This checks if a player has three X or O values in a single column, and returns true if thats the case.checkRow - This checks if a player has three X or O values in a single row.checkDiag - This checks if a player has three X or O values diagonally.checkWin() only returns true if one of these three checks is true.public class TicTacToeTester{ public static void main(String[] args) { //This is to help you test your methods. Feel free to add code at the end to check //to see if your checkWin method works! TicTacToe game = new TicTacToe(); System.out.println("Initial Game Board:"); game.printBoard(); //Prints the first row of turns taken for(int row = 0; row < 3; row++) { if(game.pickLocation(0, row)) { game.takeTurn(0, row); } } System.out.println("\nAfter three turns:"); game.printBoard(); }}public class TicTacToe{ private int turn; private String[][] board = new String[3][3]; public TicTacToe() { for(int i = 0; i < 3; i++) { for(int j = 0; j < 3; j++) { board[i][j] = "-"; } } } //this method returns the current turn public int getTurn() { return turn; } /*This method prints out the board array on to the console */ public void printBoard() { } //This method returns true if space row, col is a valid space public boolean pickLocation(int row, int col) { return true; } //This method places an X or O at location row,col based on the int turn public void takeTurn(int row, int col) { } //This method returns a boolean that returns true if a row has three X or O's in a row public boolean checkRow() { return true; } //This method returns a boolean that returns true if a col has three X or O's public boolean checkCol() { return true; } //This method returns a boolean that returns true if either diagonal has three X or O's public boolean checkDiag() { return true; } //This method returns a boolean that checks if someone has won the game public boolean checkWin() { return true; }} Read the section "No More Human Error."Which sentence from the section shows why robot referees are better than human referees?ASimilar systems could handle calls in many different sports.BIt shouldn't have any favoritism toward certain teams or players.CFor example, they can manage a player who's upset or angry.DTennis matches usually have up to nine umpires.
