Answer:

B. Directional Selection

Explanation:

By doing some research I found out what most of this means so let's do my favorite process, the process of elimination

A. Disruptive

Disruptive selection produces two or more species with two different traits nothing in the question says two different scorpions where formed one with big pinchers and another with big stingers no it just talks about them slowly forming big pinchers

C. Stabilizing

Stabilizing selection is when two species are produced with more similar traits nothing vastly different, I would consider them forming really big pinchers to be an extreme

how will a organism be benefited if it reproduces through spores

Answers

Answer:

Spore can survive under unfavorable conditions as they are covered by a hard protective coat. Spores can grow to produce new plants and does not require sexual interaction with another organism. Due to their small size and light weight, they can be dispersed easily.

Spores can remain dormant till favourable conditions become available. b. Spores help an organism to tide over the bad phase. Spores can be spread through water, air or animals and thus is good for the spread of an organism to more places.

Answers

Wanna help but where’s the diagram?

Answer:

The main job of a kidney is to filter toxins and waste products from the blood. In dialysis, the machine takes in blood from the artery and pumps it through a semipermeable membrane. This function is similar to that of the capillaries in the kidney. They allow waste products to filter from the kidneys. The waste excretes into a bag in a manner similar to how the bladder excretes urine from the body. The clean blood pumps back into the body and is carried back to the heart via a vein.

Water conservation is an important issue for many reasons. One factor is that water conservation preserves and protects our natural resources. Conserving water means more water is available to serve additional water needs, as well as for wildlife and recreation. Water conservation practices can result in lower wastewater discharges which can mean an improvement in overall water quality. Conserving water diminishes our need to find or build new water sources, leaving them in reserve for our possible later use. Preservation does result in
A) lower algae levels
B) reduction in industry standards
C) slowing the building of new housing
D) lessening the need to find new water sources

Answers

Answer:

i believe the answer is D) lessening the need to find new water sources

Answers

Answer:

1. Glucose And Oxygen.

2. Transpiration is the process by which water is lost in the form of water vapour by evaporation from the surface of leaves and other serial parts of plant .

3. A. Cooling Effect : The water keeps on evaporating from the leaf surface during transpiration . The heat required for evaporation of water is obtained from the plant itself and thus, the plant cools itself when it is hot outside.

B. Transpiration Pull : As water evaporates from the leaf surface, the roots pull up more water from the soil to make up for the water loss during transpiration .As a result, important mineral salts are also brought along with the water. These salts are necessary for the growth of the plant .

4. Leaf Tendrils : Sweet Pea

Spines : Cactus

Scale Leaves : Onion

5. Pitcher Plant, Venus FlyTrap, Blodderwort

6. Normally plants propogate with the help of seeds contained in the fruits . But some new plants may also be produced from other part of the plant such as the roots, stems, and leaves . This type of reproduction is called vegetative propogation .

To what extent can the Watergate scandal be considered a sign of strength and/or weakness in the American democracy & government? 300 students in a high school freshman class are surveyed about what kinds of pets they have. Of the 300students, 200 have a dog, 180 have a cat, and 150 have a cat and a dog. Using this information, answer each of the following questions.Let D be the event that a randomly selected student has a dog and C be the event that a randomlyselected student has a cat.What is P(D), the probability that a student in the class has a dog?What is P(C), the probability that a student in the class has a cat?What is P(D and C), the probability that a student in the class has a dog and a cat?What is P(D or C), the probability that a student in the class has a dog or a cat? The first programming project involves writing a program that computes the minimum, the maximum and the average weight of a collection of weights represented in pounds and ounces that are read from an input file. This program consists of two classes. The first class is the Weight class, which is specified in integer pounds and ounces stored as a double precision floating point number. It should have five public methods and two private methods:A public constructor that allows the pounds and ounces to be initialized to the values supplied as parameters.A public instance method named lessThan that accepts one weight as a parameter and returns whether the weight object on which it is invoked is less than the weight supplied as a parameter.A public instance method named addTo that accepts one weight as a parameter and adds the weight supplied as a parameter to the weight object on which it is invoked. It should normalize the result.A public instance method named divide that accepts an integer divisor as a parameter. It should divide the weight object on which the method is invoked by the supplied divisor and normalize the result.A public instance toString method that returns a string that looks as follows: x lbs y oz, where x is the number of pounds and y the number of ounces. The number of ounces should be displayed with three places to the right of the decimal.A private instance method toOunces that returns the total number of ounces in the weight object on which is was invoked.A private instance method normalize that normalizes the weight on which it was invoked by ensuring that the number of ounces is less than the number of ounces in a pound.Both instance variable must be private. In addition the class should contain a private named constant that defines the number of ounces in a pound, which is 16. The must not contain any other public methods.The second class should be named Project1. It should consist of the following four class (static) methods.The main method that reads in the file of weights and stores them in an array of type Weight. It should then display the smallest, largest and average weight by calling the remaining three methods. The user should be able to select the input file from the default directory by using the JFileChooser class. The input file should contain one weight per line. If the number of weights in the file exceeds 25, an error message should be displayed and the program should terminate.A private class method named findMinimum that accepts the array of weights as a parameter together with the number of valid weights it contains. It should return the smallest weight in that array.A private class method named findMaximum that accepts the array of weights as a parameter together with the number of valid weights it contains. It should return the largest weight in that array.A private class method named findAverage that accepts the array of weights as a parameter together with the number of valid weights it contains. It should return the average of all the weights in that array.Be sure to follow good programming style, which means making all instance variables private, naming all constants and avoiding the duplication of code. Furthermore you must select enough different input files to completely test the program.Java programmingThe text file could not be attached but it looks like this:Year,Weight in Lbs,Weight Loss Rate1994,713.6,91995,684.5,8.21996,636.6,7.41997,611,6.81998,567.6,6.31999,523,5.72000,506.5,5.52001,504.5,5.62002,494.4,5.62003,475.8,5.72004,463.2,5.52005,469,5.62006,479.3,5.82007,471.8,5.72008,458.6,5.42009,431.9,52010,404.5,4.82011,387.1,4.72012,387.8,4.72013,367.9,4.5please tell me what to do?
