Which component of whole blood is primarily responsible for maintaining the pH of blood and body tissues within normal limits?
Answer:
Plasma.
Explanation:
Plasma is the liquid component or constituent of the blood after the removal of all the cells and platelets. It is composed of 90% water, coagulation factors like antibodies, electrolytes, proteins , lipids e.t.c which help to maintain the blood PH and osmotic balance of the blood during the process of giving viscosity to the blood. The plasma comprises of 55% of the blood.

Why is evolution considered to be a scientific THEORY?
Answer: Evolution is considered to be a scientific theory because evolution is not proven true of false, although it is widely recognized as true. A theory is defined as "a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained", meaning that it is the compliation of a certain ideas in hopes of proving something as true. The theory of evolution is the use of facts to try to explain how species have evolved over time. We have been unable to prove evolution as it occurs in front of us, but we can use evidence to support this theory.

True or False: A negative electric charge represents a positive number. *
Answer:
False.
Explanation:
A negative charge dies not represent positive numbers because a negative charge represent negative number.
Electrons are negative charge and they represent negative numbers like -1, - 2, et.c. protons represent positive charges and when to negative charges come together, they repel each other likewise positive charges but if negative charges and positive charges come together, they attract each other.
3. Glucose dissolves in water because it BLANK
Select one:
O A. ionizes
O B. is a polysaccharide.
O C. is polar
O D. is nonpolar
Answer:
C
Explanation:
glucose is polar, meaning that there is a separation of charge present in the observed molecule
water is also polar as it contains electronegative oxygen, which pulls electrons towards itself, forming a dipole of partial positive (H) and partial negative charge (O)
a simple rule of thumb is "like dissolves like"
Glucose dissolves in water because it is polar. Therefore option C is correct.
Glucose, a simple sugar, and a monosaccharide is a polar molecule, meaning it has a slight positive charge on one end and a slight negative charge on the other due to its asymmetrical arrangement of atoms.
Water molecules are also polar, with a positive end (hydrogen) and a negative end (oxygen). Like dissolves like, so the polar nature of glucose allows it to interact with water molecules through hydrogen bonding, effectively surrounding and stabilizing glucose molecules in solution.
This enables glucose to dissolve in water, forming a homogeneous mixture and allowing it to be transported and utilized within living organisms for energy production and other essential processes.
Therefore option C is polar is correct.

What is true about the two daughter cells formed after the binary fission of a bacterium cell?
1.They have variations in the primary DNA but have the same set of plasmids.
2.They have variations in the primary DNA but may have a different set of plasmids.
3.They have the same primary DNA and the same set of plasmids.
4.They have the same primary DNA but may have different plasmids.
Answer:
They have the same primary DNA but may have different plasmids.
Explanation:
i took a test and got the question right
The option that's true about the two daughter cells formed after the binary fission of a bacterium cell is D. They have the same primary DNA but may have different plasmids.
Binary fission simply means asexual reproduction when a body is separated into two different bodies.
It should be noted that during binary fission, the genetic material of an organism is duplicated and this enables the two new organisms formed to be able to have their separate copy of DNA.
In a bacterium cell, when the two daughter cells are formed after the binary fission, they have the same primary DNA but may have different plasmids.

1.Which type of rock may result when sedimentary rock is exposed to extreme heat and pressure?
a. clastic
b. extrusive
c. igneous
d. metamorphic
2. In the rock cycle, how does rock become sediment?
a. Through weathering and erosion
b. through crystallization and solidification
c. through heat and pressure
d. through compaction and cementation
3. A Sedimentary rock containing a fern fossil was found. what does this tell about the area at the time the rock was formed?
a. The area was hot
b. The area was covered by and ocean
c. The area was cold
d. The area was on a land
Answer:
1:(D), 2:(D), 3:(D)
Explanation:
1) When a rock is exposed to heat and pressure, it becomes a metamorphic rock. This is correct, because this is the process that forms a metamorphic rock.
2) A rock becomes sediment through weathering and erosion. In this question, they are not asking you to explain the process of sedimentary rock formation, they are asking you how a rock becomes sediment. The process of weathering and erosion breaks down a rock, and turns that rock into smaller peices, which therefore, through the process of compaction and cementation forms a sedimentary rock.
3) A fern is a land plant. It is not found in the sea and there is not enough information given to tell whether or not the area was hot or cold. This leaves us with D. We can tell that this fossil is a land fossil because ferns do not grow in the ocean.

During the process of DNA replication, a complementary DNA strand is formed. If the original strand of DNA is 5' ATA GTG CCC AAC GGT 3', which of the
following would be the correct complementary DNA strand?
Answer:
This question lacks options, the options are as follows:
A. 3’ ATA GTG CCC AAC GGT 5’
B. 3’ TAT CAA GGG TTG CCA 5’
C. 3’ TAT CAC GGG TTG CCA 5’
D. 3’ TAT CAC GGG TTG CCT 5’
The answer is C
Explanation:
DNA replication is the process by which a DNA molecule makes a copy of itself i.e. duplicated. In this process, the double-stranded DNA molecule splits into two single strands, which each serves as template for the synthesis of another strand. The new strand is synthesized using the COMPLEMENTARY BASE PAIRING RULE.
Complementary base pairing rule states that an Adenine base will always hydrogen bond with a Thymine base while Guanine base will always hydrogen bond with Cytosine base i.e. A-T, G-C. Hence, given the original strand of DNA in this question, the complementary strand will have the following sequence: 3’ TAT CAC GGG TTG CCA 5’
