Answer: G and C
Explanation: DNA carries the hereditary information for organisms. W ithout DNA, our species would be unable to pass traits from generation to generation. DNA controls all aspects of an organism. It tells spiders how to spin webs, birds to lay eggs, and what color to make your eyes. The genetic information in DNA is stored as special chemical sequences, called chemical bases. The chemicals bases are adenine (A), guanine (G), cytosine (C), and thymine (T). Each base connects with another to form base pairs. Adenine always pairs up with thymine. Cytosine always pairs up with guanine

All organisms must have water for survival. If a drought causes the water in an ecosystem to become scares the organisms in this
ecosystem will not have as much water accessible to them
A decrease in the water available to an organism for cellular processes will most likely result in
CA
a decrease in optimal temperature ranges
e.
an increase in activity level
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.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.

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.

Honey Bees have a much different social and reproductive structure as compared to humans.
With honey bees, the queen bee contains more chromosomes with 32 than her drones do at
16 chromosomes. If the queen bee is identified as a Diploid, how would the drones be
classified?
O Haploid
O Diploid
O Monosomy
O Trisomy
Answer:
Unlike the queen bee, which has 32 chromosomes, drones have half the chromosomal charge (n= 16), so they are considered haploid.
Explanation:
The system of determination of the sex in the bees —like in other insects— is called haplodiploidy, and consists of which the females of the species possess complete charge of chromosomes, whereas the males only possess half. This is what happens with the queen bee with 32 chromosomes, while drones only have 16 chromosomes, so they are considered haploid.
Additionally, as a characteristic of haplodiploidy, males only proceed from female gametes, so they can only contribute gametes to produce females of the species.
The other options are not correct because:
Drones, with half of the chromosomal charge, cannot be diploid. Monosomy and trisomy are defects in the distribution of chromosomes during meiosis, which imply one chromosome less or one chromosome more in the normal chromosome charge respectively.This is one explanation of enzyme specificity that states an enzyme and its substrate possess specific complementary geometric shapes that fit exactly into one another.

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.

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.
