Explanation:
White blood cells are especially active when you are sick because their primary job is to fight off infections – often bacteria or viruses that do not belong in you. Once they locate the invader making you sick, they eat it and destroy it. What organelle do you think is plentiful in white blood cells?
Answer:
Lysosomes
Explanation:
Lysosomes are membrane bound organelles that contain degradative enzymes. They degrade worn-out cellular parts and may also be used by cells to degrade/destroy invading bacteria or viruses. Hence, since white blood cells are primarily responsible for fighting infections, it is expected that they have a high amount of lysosomes (which they indeed do have in high amount).
how do plant cells differ from animal cells structurally?
Answer:
plant cells have a rigid cell wall that helps it keep shape and animal cells don't
Answer:
Plant cells contain a cell wall to help give better structure and protection than animal cells. Plant cells also contain a large central vacuole that is used to store waste and water. Another thing is that plant cells have an organelle that preforms photosynthesis.

Why do you think DNA is called a double stranded molecule?
A carbon atom has 6 protons and 6 electrons. Carbon has three naturally occurring isotopes, carbon-12, carbon-13, and carbon-14. Which of these statements is true about carbon and its isotopes? A.All carbon atoms have six neutrons. B.All carbon atoms have six protons and six electrons. C.Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons.
Answer:
The correct option is B
Explanation:
Isotopes of the same element have the same atomic number (number of protons) but different mass number. Hence, all the three naturally occurring carbon isotopes mentioned in the question have 6 protons each. Since the number of protons in a neutral atom is equal to the number of electrons in the same atom, each of these isotopes also have 6 electrons.
However, to determine the number of neutrons in each atom, the number of protons (atomic number) is subtracted from the mass number.
Hence, the number of neutrons in carbon-12 is 12 - 6 = 6
the number of neutrons in carbon-13 is 13 - 6 = 7
the number of neutrons in carbon-14 is 14 - 6 = 8
From the explanation above, it can be noted that the number of protons and electrons in isotopes of the same element are the same while the number of neutrons in these isotopes are different. Hence, the correct option is B

1) The property of matter that describes a solvent is mixing with a
solute to make a solution is known as
A. Contraction
B. Density
C. Solubility
D. Energy
Help!!
Answer:
C. Solubility
Explanation:
Solubility of a substance refers to the ability of a substance called the SOLUTE to dissolve in another substance called the SOLVENT to form a SOLUTION. Matter, which constitutes the solid, liquid and gaseous state, can be the solute, which will get dissolved in the SOLVENT (usually a liquid).
Therefore, according to this question, the property of matter that describes a solvent is mixing with a solute to make a solution is known as its SOLUBILITY
Imagine a science fiction movie in which a scientist creates a new species of organism. The scientist generates a whole population of the organism entirely through cloning of the males and females and then leaves them on an island. Explain why the population of clones would struggle to evolve if there was a major environmental change on the island.
The population of clones that struggle to evolve if there was a major environmental change on the island is :
-Lack of variations in the population as the clones are products of without fusion reproduction.
"Environmental change"The population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.
Without fusion reproduction will allow the parent organism to produce offspring that are exactly identical to the parent.
Also it will help in production of large number of progenies at a single time.
Therefore, the population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.

Question:
The complete question has these options:
A) tRNA with anticodons is carrying amino acids to the ribosomes.
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Answer:
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Explanation:
During transcription, RNA polymerase uses DNA as a template to create a new molecule of mRNA via complementary base pairing
A) tRNA with anticodons is carrying amino acids to the ribosomes. - this is not evidence of transcription but is instead evidence of translation
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules. - this is false, DNA polymerase is the enzyme that performs DNA replication not transcription.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins - this is not evidence of transcription but is instead evidence of translation
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production - this accurately describes the process of transcription.

4. a. viral genome is replicated using host cell's machinery
5. d. new viruses are assembled within host cell
6. e. the cell ruptures and releases new viruses to infect new cells
Explanation:
First, the virus attaches to the cell. Then it penetrates the cell membrane and inserts its genome inside the cell. The virus relies on the cell machinery to synthesize its proteins, and also to replicate its genome.
With these components being synthesized and replicated, new viral particles are assembled inside the host cell. Eventually, the cell ruptures, and the newly assembled viruses are released and able to attach to new cells to repeat the cycle

D
The enzyme's activity continually increases as pH increases
from 5.0 to 9.0
Answer:
A
Explanation:
A. The optimum pH of the enzyme is 6.6. - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)
B. The optimum pH of the enzyme is 5.8. - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80
C. The enzyme's activity is greater around pH 8.0 than around pH 5.0 - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.
D . The enzyme's activity continually increases as pH increases from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.

Which abiotic factors would you expect to influence the growth of trees in the mountains?
Number of deer and insects
Types of trees and plants
Rainfall and the location on the mountain
Predator and prey population
Answer:
Rainfall and the location on the mountain
Explanation:
This is the answer because:
Rainfall highly helps the trees on the mountains grow. The location of a tree also matters a lot because it has to be in a spot where it can reach sunlight and lots of rain.
Therefore, the answer is Rainfall and the location on the mountain.

in what ways is ATP like a fully charged battery?
Answer:
ATP ATP can be compared to a fully charged battery because both contain stored energy, whereas ADP resembles a partially charged battery. Releasing Energy From ATP The energy stored in ATP is released when ATP is converted into ADP and a phosphate group.
Explanation:
The ATP molecule is comparable to a battery that can be recharged. It is ATP when ultimately charged. It's ADP when it's worn out. When the battery runs out, it is simply recharged rather than discarded.
What is ATP?A vital "energy molecule" in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers cells' energy by liberating its phosphate groups when it interacts with enzymes like ATP triphosphatase. The molecule comprises an adenine bicyclic system, a furanose ring, and a triphosphate chain.
The discovery of ATP was announced in 1929 by two research teams. It was isolated from mammalian muscle and liver by Cyrus H. Fiske and Yellapragada Subbarow at Harvard Medical School (Boston). Karl Lohmann discovered it in muscle tissues while working for the Kaiser Wilhelm Institutes in Berlin and Heidelberg.
Over the next 15 years, ATP separation from other sources came next. In 1987, Koscak Maruyama of Chiba University (Japan) provided a thorough analysis of ATP's discovery and structural elucidation.
Therefore, ATP is like a rechargeable battery because it can be recharged and discharged.
