The diagram to the right shows an HIV particle.
What is the function of the glycoproteins on the outside of the virus?
A. to carry genetic material
B. to propel the virus forward
C. to help the virus invade cells
D. to protect the HIV particle from antibodies
The function of the glycoproteins on the outside of the virus is to help the virus invade cells (Option C).
What is a virus?A virus is an entity (not an organism) that is able to infect the cells of a given sensitive host.
A virus is covered by a layer called the coat, which is composed of glycoproteins to infect suitable hosts.In conclusion, the function of the glycoproteins on the outside of the virus is to help the virus invade cells (Option C).

which one ^
Answer:c
Explanation:
B.
A mutation causing an organism to lose its arm would be harmful and a mutation which does nothing is neither harmful nor beneficial.

during simple diffusion and
facilitated diffusion?
A. Simple diffusion moves large
molecules.
B. Facilitated diffusion requires energy.
C. Facilitated diffusion uses protein
channels.
Answer: C

7C. The diagram below represents four different species of bacteria.
Which statement is correct concerning the chances of survival for these
species if there is a change in the environment? *
Species A
Species B
Species C
Species D
ATID
Neither species B nor species D will survive because they compete for the same
resources
Species A has the best chance of survival because it has the most genetic diversity
Species C has the best chance of survival because it has no gene mutations
None of the species will survive because bacteria reproduce asexually
Answer:
A bcoz it change the environment
Species A has the best chance of survival because it has the most genetic diversity.
What is genetic diversity?Genetic diversity is defined as the set of different inherited traits that occurs within a species. Those organisms having higher genetic diversity have more chances of survival.
So we can conclude that Species A has the best chance of survival because it has the most genetic diversity.

Explain what happens to a cell as it enters the cell cycle and goes through the process of
MITOSIS. Tell what happens to the cell at each part of the cell cycle starting at
Interphase, then the stages of Mitosis (PMAT) and ending at Cytokinesis. (This should be
a longer response than one sentence!!)
Answer:
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
Explanation:
During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

The Main Sequence:
The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium. ... For the Sun, this process began 4.57 billion years ago, and it has been generating energy this way every since.

Genetic variation is inherited by offspring.
A. Artificial aelection
B. Natural Selection
C. Both
Answer:
Both
Explanation:
A person's skin color, hair color, dimples, freckles, and blood type are all examples of genetic variations that can occur in a human population. Examples of genetic variation in plants include the modified leaves of carnivorous plants and the development of flowers that resemble insects to lure plant pollinators. Even though in artificial selection, you take which genes are desired it is still passing genetic variation through offspring.

what is the definition of natrual asexul reprduction?
Answer:
In natural asexual reproduction, roots can give rise to new plants, or plants can propagate using budding or cutting. In grafting, part of a plant is attached to the root system of another plant; the two unite to form a new plant containing the roots of one and the stem and leaf structure of the other.

Explanation:
because mitosis is a process where a single cell divides into two identical daughter cells
More than 2000 years ago, the Greek philosopher Aristotle classified
organisms into plants and animals,
He placed all animals into 3 groups:
• land dwellers
• water dwellers
• air dwellers
In addition, he placed all plants in 3 different groups based on differences in
their stems:
herbs
· shrubs
• trees
What was the most likely reason that this system eventually changed?
.
.
A)Aristotle's method was too specific.
B)Two thousand years ago, no one accepted classifying organisms into plants and animals.
C)Many organisms were placed in groups to which they had no real relationship with the other
members of the group.
D)All organisms containing chlorophyll belonged in the same kingdom.

What do all vectors and scalars have?
A. velocity
B. orientation
C. direction
D. magnitude
Answer:
D. magnitude
Explanation:
Scalars are quantities that are fully described by their magnitude (size) only. For example, a temperature is fully described by saying "80 degrees Celsius." We do not need to include a direction.
A vector contains both magnitude and direction. Acceleration is fully described by including both speed and direction: "45 m/s, North."
Both scalars and vectors have magnitude.
