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
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.

Yeasts reproduce by budding. During budding, a yeast cell splits into two cells. Then the two cells split, making four cells. Determine how many yeast cells would result from 5 buddings.
Show your work.
Answer:
20 yeast cells would be formed.
Explanation:
You have five cells. Each of those five cells split into two, so now we have 10 cells. Think about it like multiplication, so 5 times 2 = 10. Now we have 10 cells. We know that they split even further, so now those 10 cells become 20 cells. Here is a more simple explanation:
5 cells:
* * * * *
Now those five cells split up into 2:
* * * * *
* * * * * * * * * *
Then those new ten cells split into four:

Stem cellsWhich of the following is true of pine rockland habitats?
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.

Chloroplasts are found in Eukaryotic Autotrophs i.e. those who can make their own food with the help of sunlight using carbon dioxide and water. Eukaryotes are Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
_____________________________________Example:The Example of Eukaryotic Autotrophs are Plants and Algae. They are the producers in the food chain also the main source of the oxygen, as they use Carbon Dioxide for a glucose's carbon structure and releases oxygen as By-Product.
_____________________________________Why are they green?Chloroplasts get their green color by the presence of chlorophyll, which is the main site for the process of photosynthesis. It is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Chlorophyll absorbs mostly in the blue and all the other colors to the lesser extent while reflecting green. They are present in leaves, and as the chlorophyll reflect green color, Thus the leaves look green to us.

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

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.
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.

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
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.
A group of scientists recently proposed the idea that beets should replace salt for melting winter ice. The scientists pointed out that because beets grow underground, they continue to grow in freezing conditions. Thus, they hypothesized, an extract of beet roots could melt ice on roads in winter. Make a prediction.
Answer:
Extract of beet roots has the capacity to melt ice
Explanation:
A prediction in research is a tentative statement that can be proven or disproven using an experiment. Predictions are otherwise referred to as hypotheses.
In the illustration, the prediction would be that the extract of beet roots has the ability to melt ice. After the experiment, the prediction would either be proven right or otherwise.
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?
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.
