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.

When the concentration (amount) of molecules on both sides of a membrane is the same, the molecules will ________.
Answer:
continue to move across the membrane in both directions
Explanation:
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.

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.

Explain how signaling pathways are deactivated for transduction parts of a signaling pathway.
Explanation:
cAMP binds to protein kinase A and activates it, allowing PKA to phosphorylate downstream factors to produce a cellular response. cAMP signaling is turned off by enzymes called phosphodiesterases, which break the ring of cAMP and turn it into adenosine monophosphate (AMP).

7. How does the plant lichen quicken the weathering process? *
(1 Punto)
They eat the rocks
They create new bacteria that breaks away rocks
They secrete acid that breaks away rocks
They eat the acid in rocks
Answer:
The correct answer is - They secrete acid that breaks away rocks
Explanation:
Lichen causes chemical weathering to break the rocks quickly which is the excretion of various acids like oxalic acid and many more organic acids that can cause a significant impact on the rock by dissolving minerals.
By breaking the rocks it forms the ground for the plant that will come later in place of the bare rocks by this chemical weathering process. An example of chemical weather is a change of the granite to clay with the help of hydrolysis.

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.
Hope I could help, and best of luck!

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.
In the ionic compound KF, what is the charge on K?
positive
partial positive
negative
ООО
partial negative
no charge
Answer:
Charge on K is +1.
Explanation:
This gives potassium eight valence electrons in its third energy level, and flourine eight valence electrons in its second energy level. This also produces a potassium cation K+ with +1 charge and a flouride anion F- with -1 charge.

Coding of a Polypeptide by Duplex DNA The template strand of a segment of double-helical DNA contains the sequence (59)CTTAACACCCCTGACTTCGCGCCGTCG(39) (a) What is the base sequence of the mRNA that can be transcribed from this strand
Answer:
GAAUUGUGGGGACUGAAGCGCGGCAGC
Explanation:
The process whereby a mRNA molecule is formed from a DNA template is called TRANSCRIPTION. The mRNA formation follows the complementary base pairing rule which says that Adenine is bonded to Thymine (Uracil in RNA) i.e A-T(U) while Guanine is bonded to Cytosine i.e. G-C.
Based on this, a DNA molecule with base sequence: CTTAACACCCCTGACTTCGCGCCGTCG will be transcribed into a mRNA strand with base sequence: GAAUUGUGGGGACUGAAGCGCGGCAGC

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.
