Answer:
because it's not included as a living thing until it has entered and organism that is living
Explanation:
Answer:
Viruses are not living things.
Explanation:
Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.

The diagram below is a model of the process of transcription.
What is the purpose of strand B?
a) To act as a template for the synthesis of messenger RNA
b) To carry the code from the DNA molecule in the nucleus to the ribosome
c) Delivers specific amino acids to the ribosome to make proteins
d) Transfers nucleic acids to the nucleus
Answer:
b
Explanation:
The purpose of the strand B be would be to carry the code from the DNA molecule in the nucleus to the ribosome.
Looking closely at the diagram, strand B is the strand of RNA that is still in the process of being synthesized while strand A is acting as the template. The function of the RNA strand is primarily to carry an encoded message in the DNA molecule from the nucleus to the ribosome in the cytoplasm where the genetic codes would be translated during the process of protein synthesis.
The correct option is, therefore, b.
The purpose of strand B would be to carry the code from the DNA molecule in the nucleus to the ribosome (option b)
The strand B shown in the figure represent the RNA transcript derived from the transcription process due to the presence of uracil which is always found in RNAs.
After undergoing a series of processes including transcriptional control, they become mRNA and are transported to the ribosome to undergo translation to proteins.

Which was Charles Darwin’s contribution to the study of biology?
He was the first person to recognize that organisms change over time.
He believed that organisms adapted through the inheritance of acquired traits.
He explained how traits are passed from parents to offspring.
He proposed that natural selection is the primary mechanism of evolution.
Answer:
d
Explanation:
Charles Darwin proposed that natural selection is the primary mechanism of evolution. The correct option is D.
What is natural selection?Natural selection is the method by which living organism populations adapt and change.
Individuals in a population are innately variable, which means they diverge in the some ways. This variation indicates that some people have traits that are better adapted to their surroundings than others.
Natural selection, Darwin proposed, is a mechanism for evolution in which heritable traits that help support life reproduce and survive are becoming more prevalent in a population over time.
Natural selection occurs when genes that confer a survival or reproductive advantage are handed down and persist in a population, whereas genes that result in lower survival or fewer offspring are becoming less common.
Thus, the correct option is A.

Which of these is an example of active transport?
A Glucose molecules move against the concentration gradient across the cell membrane with the help of ATP.
B. Carbon dioxide molecules diffuse freely across the cell membrane.
C. Water molecules move down the concentration gradient across the cell membrane with the help of a channel protein.
D. Oxygen molecules become trapped inside the cell membrane with the help of ATP.
Answer:
a. glucose molecules move agnst the concentration gradient across the cell membrane w the help of atp
Explanation:
active transport requires energy (atp) to push a molecule agnst its concentration gradient
also glucose molecules r too large to cross without the help of transmembrane proteins
and oxygen molecules r able to get thru by simple diffusion bc they r small enough
Glucose molecules move against the concentration gradient across the cell membrane with the help of ATP is an example of active transport.
Active transport is a biological term to refer to the movement within the cell in which some molecules move across the cell membrane. This movement requires energy from cells to move.
According to the above, when a glucose molecule moves against the concentration gradient across the cell membrane and in this movement it consumes energy (ATP) it is carrying out active transport.
According to the above, the correct answer is A. because it exemplifies active transport.

Who do the hurricane hunters give data to?
A) National weather service in Miami Florida
B) National hurricane center in Norman Oklahoma
C) National Hurricane Center, in Miami Florida
D) National weather service in Norman Oklahoma
Answer:
C) National Hurricane Center, in Miami Florida
Explanation:
"Hurricane hunters" refer to people who gather data about tropical cyclones by actually flying into them. This allows them to obtain the actual barometric pressure of hurricanes, including the wind flow speed. The data gathered are then sent to the "National Hurricane Center," which is located in Miami Florida. It has the mission to analyze dangerous storms in order to save many lives by warning people and providing weather forecasts. They also monitor those locations with disturbed weather conditions.
Hurricane hunters give data National Hurricane Center, in Miami Florida. The correct option is C.
Thus, The National Hurricane Centre (NHC), located near Miami, Florida, receives the majority of the data collected by the U.S. Air Force and NOAA (National Oceanic and Atmospheric Administration) aircraft known as the "Hurricane Hunters" as they fly into hurricanes.
Tropical storms and hurricanes in the Atlantic and Eastern Pacific basins must be tracked and forecast by the NHC.
Meteorologists at the NHC use the data gathered by the Hurricane Hunters to enhance hurricane track and intensity forecasts.
Thus, Hurricane hunters give data National Hurricane Center, in Miami Florida. The correct option is C.

The molecule BPG binds to the deoxy form of hemoglobin in the central cavity. Explain why that makes sense for oxygen delivery and why BPG is said to stabilize the deoxy state.
Answer:
Oxygen binds with the hemoglobin to carry the blood to different body parts through the circulatory system. The binding of the oxygen to Hb is regulated by the Bisphosphoglycerate or BPG molecule. It is bounded to the deoxy form of hemoglobin.
BPG binds with deoxy Hb in the central cavity of the four subunits which decreases the affinity to hemoglobin. The binding of BPG stabilizes T form or deoxy-Hb as the central cavity is larger in T form in comparison to the R state. R state has a low affinity to oxygen due to relatively smaller central cavity.

Which of the following processes is most likely to occur as a result of an
animal cell receiving a signal to initiate apoptosis?
Answer: lysosomes will release digestive enzymes into the cytosol
Explanation:
Apoptosis is one of the cellular mechanisms of cell death in a controlled manner. At the initiation of apoptosis, the lysosomes start secreting the digestive enzymes in the cytoplasm. Thus, option D is correct.
What is apoptosis?Apoptosis has been defined as programmed cell death in multicellular eukaryotes. It involves biochemical steps that involve cell shrinking, fragmentation of the nucleus, condensation of chromatin structure, decay of the mRNA, and the disintegration of the DNA.
It is a significant process in animal cells as it destroys the unwanted and harmful cancerous cells that can damage the body. They are very crucial in cancer and are initiated by the alteration in the survival signals and sudden dissociations.
The lysosomes play an important role in apoptosis as they're the specialized organs that release digestive enzymes that initiate cell death. They undergo autolysis when the signals for apoptosis are initiated.
Therefore, in option D. the lysosomes are responsible for apoptosis.

Inside the cell is 40% helium and outside the cell is 20% helium. Which of
the following will occur? *
A. helium will move out of the cell
B. helium will move into the cell
C.helium will not move
Answer:
A. Helium will move out of the cell
Inside the cell the concentration is higher than concentration off outer cell so the inner helium well more about of cell
Answer:
[tex]\boxed {\boxed {\sf A. \ Helium \ will \ move \ out \ of \ the \ cell}}[/tex]
Explanation:
Diffusion is the movement of particles from a high concentration to a low concentration. This is the process occurring in this question.
In this cell, 40% helium is inside the cell.
20% is outside of the cell.
40 is greater than 20. Therefore, the helium wants to move from the area of 40% to 20%, which is also from the inside of the cell to the outside. Basically, the helium moves out of the cell.
So, the best answer is choice A: helium will move out of the cell.
