Which of the following is true of pine rockland habitats?​

Answers

Answer:

Dry habitat.

Explanation:

Pine rockland has a dry habitat due to their location on higher ground. Pine Rocklands, also known as the Pinelands which have a hard rocky ground, made up of limestone. Pine rockland is an endangered habitat because 98 percent of the original habitat is lost while only 2 percent is remaining. This is due to the increase in population so the human clears the area for building places.

Explanation:

A marathon runner completed a race of 26.2 miles in 3 hours and 15 minutes. What was his average speed throughout the race?

a) 7.5
b) 8.1
c) 8.7
d) 10

Answers

Answer:

b

Explanation:

The average speed of an object is the sum of the distance traveled by the object relative to the total time taken to cover the distance. In other words,

Average speed = total distance traveled/total time taken

In this case, the total distance traveled by the runner = 26.2 miles while the total time taken = 3 hours and 15 minutes

60 minutes = 1 hour

15 minutes = 0.25 hours, hence

3 hours 15 minutes = 3.25 hours

Average speed = 26.2/3.25

                          = 8.0615 miles/hour

                            = 8.1 miles/hour

The correct option is b.

Which of these is a characteristic of sexual reproduction?A)It takes place in all cells of the body.B)It forms exact copies of the parent cell.C)It results in offspring with genetic variation.D)It requires only one parent to form a daughter cell.

Answers

Answer/Explanation:

It results in offspring with genetic variation. 2 different mates must be used in sexual reproduction. This is because each person is different since cells are produced and combined differently in the original offsprings. If the two adults were exactly the same, the offspring would have the exact same cell traits. Likewise will be done for the offspring of the two adults. The genes may be similiar to the ones of the adults, but since combined it will not be an exact replica. In the long run sexual reproduction will result in an offspring with slightly different traits or genetic variation.

C, a decrease in metabolic activity
an increase in metabolic activity

Answers

Answer:

C, a decrease in metabolic activity

Explanation:

Water is an essential compound needed for the survival of all organisms in nature.

The bulk of most organisms is made up of water. Most importantly, water is integral part of cellular metabolic processes.

In the time of drought, metabolic activities will reduce. Organisms will tend to be inactive so as to conserve the little water they might have access to. This is an important adaption for organisms.

Explanation:

At 1:00 a.m., someone breaks a window in the back of a store and robs the safe. On the way out, the thief cuts himself (or herself) on a piece of the broken glass. You are a forensic detective called to the scene. You test the sample of blood left behind by the thief. It is O-. While you are there, police bring in a suspect with a cut in the forearm who was arrested just three blocks from the store. You take a sample of the suspect’s blood and mix it with anti-A. You immediately know that the suspect is not the person who cut himself on the broken glass in the store. How do you know this?
2. Suppose the same suspect's blood does not agglutinate when tested with anti-A or anti-B, but does agglutinate when tested with anti-Rh. Would this connect the suspect with the crime scene? Explain
3. Tom and Jane participate in a Red Cross blood drive. Both are first-time donors. As part of the screening.
A. What ABO antibody is found in Tom's blood?
B. What ABO antigens are found in Janes blood?
4. The same Tom and Jane's blood donations are sent to a processing center where the blood cells from the plasma in each of the two samples. The separated cells and plasmas are then sent to a hospital. A blood researcher wishes to use Tom's blood in an attempt to extract and identify the A antigen. Should she attempt the extraction process on his blood cells or on his plasma?

Answers

Answer:

Explanation:

When a blood group matches with an antibody it agglutinate this indicate an agreement furthermore when they do not agglutinate it denotes they aint compatible.

The suspect's whose blood is unknown on mixing with anti-A blood agglutinate and is immediately ruled out this is because the criminal who is 0- should agglutinate with anti-B.

When the suspect blood agglutinate on testing with anti-Rh it indicates that the suspect is O+ and not O-

Plasma are mostly filled with water blood samples should be extracted from blood cell.

A blood test is done by using chemicals that coagulate with the blood sample if it is positive for the test.

1. The suspect was not the same person was determined by using the blood test.

When the sample from the suspect is taken and mixed with the Anti A it would have got coagulated.

For a blood sample to be O⁻ it should not agglutinate with either Anti A or B antibodies as the blood group O does not contain any antigen on its cell surface.

2. If the blood sample does not agglutinate for both the Anti A and Anti B antibodies it indicates the blood type to be O.

But if agglutinates with the anti-Rh that means that it is an O⁺ blood group and not O⁻.

Therefore, it cannot be connected with the crime scene.

3. A. Tom's blood group is A+ the ABO antibody can be determined by:

According to the ABO blood group system, two types of antibodies are present antibody A and B in the plasma while two types of antigens anti - A and B are found in the blood cells.

Tom have blood group A+ that means that he has antigen A in his RBC while antibody B is in his plasma.

Therefore, Tom has antibody B in his blood as he is A+.

B. Jane's blood group is AB+ which means that Jane has both the antigen A and B in her blood cells while there are no antibodies in her plasma.

4. The process of the extraction of antigen A from Tom's sample should be done from the blood cells as RBC contains the antigen while plasma is of no use because they contain the antibodies.

Which of the following is the best evidence to support the belief that air is matter?

A you can't see air
B you can feel air blown from a fan
с air weighs nothing and has no mass
D air is what we breathe

Answers

Answer:

Explanation:Its C

We can feel air blowing from a fan because air is matter. It has its volume and mass. Thus, option B is correct.

What is the matter?

Something that has volume and mass is called matter, which occupies space and can be weighed. The matter is affected by gravity due to its mass. There are generally three states of matter and that are solid, liquid, and gas. Everything you can see is matter. It is made up of very fine particles and we can not see these particles by the eye.

Even if air can not be seen but it has a volume and it can be weighed. When we blow a balloon, air goes inside the balloon, and its size increases because air has, it takes up space and we can weigh the balloon.

We can feel wind because air is matter. Therefore, the correct option is B.

Root systems are classified as fibrous root systems and taproot systems.

Which property distinguishes the two types of root systems from each other?


A)
the method of water absorption

B)
the branching pattern of the roots

C)
the presence of xylem and phloem

D)
the growth rate of the roots

Answers

Answer:

B)  the branching pattern of the roots

Explanation:

Plant roots function as anchors,  food storage and aid in the uptake of water and minerals- other modifications include gas exchange and chemical signaling.

Root systems are mainly classified as taproots, usually found in dicots or fibrous roots found in monocots - some plants are a varying combination of the two systems.  While tap roots consist of a larger, vertical main root surrounded by smaller lateral roots, fibrous roots are typically a dense network of roots that grow near the surface of the soil.

Taproots are thought to be more common in plants inhabiting regions experiencing water scarcity, while fibrous roots are thought to grow in more lush, water-abundant regions.

Examples of these roots systems include...

taproots: dandelions, carrots, turnipsfibrous roots: grasses, corn

American officials wanted to avoid the problems that caused France to abandon the project. They wanted to protect workers from disease. An engineer, John F. Stevens, was sent to the work camp in Panama. He began building hospitals as well as water and sewage systems making the working conditions sanitary. He supported the camp doctors efforts to fight mosquitoes, the cause of malaria and yellow fever. All of these efforts helped to keep the workers healthy and focused on the task at hand.Using the Panama Canal Since the water level of the Pacific and Atlantic Oceans is not the same, a system of locks and gates had to be built in the canal. These locks are a pathway for ships to move from one ocean to the other. A lock is a giant box made of concrete. A ship must pass through three locks in the Panama Canal. Each lock holds millions of gallons of water. A ship moves into a lock, which is filled with water. Water is pumped into the lock or out of the lock. This raises or lowers the ship to the level of water in the next lock. The gates open, and the ship moves into the next lock. By early 1913, the canal was nearly complete. It took several months to fill the canal with water. On September 26, 1913, an old tugboat was the first ship through the canal. Thousands of people watched and cheered. The locks worked perfectly. In modern times, approximately 14,000 ships make the 50-mile trip through the canal each year. On average, the trip through the canal takes a ship 8 to 10 hours. The ship captain does not steer the ship through the canal. A specially trained canal pilot takes control of the vessel and expertly guides it through the canal. Time, money, and possibly even lives have been saved as ships use the shorter route from ocean to ocean provided by the canal. The Panama Canal, a highway of water, is a phenomenon.
