how does the virus use a host cell to make copies of itself

Answers

Answer:

I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.

If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).

In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.

In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.

Trait B decreased in frequency over time. So, the correct option is A.

What is trait?

A trait is an attribute or characteristic of an organism that is influenced by its genes, according to genetics. Behavioural and physical characteristics, including intelligence and friendliness, can be altered by a combination of hereditary and environmental variables.

A trait is a distinctive quality or attribute that can be acquired by environmental circumstances, genetic inheritance, or both. In biology, traits are observable and quantifiable qualities of an organism, including its physical characteristics, behaviour, and other traits. For instance, physical characteristics like eye colour, height, and hair texture can all be passed on through genetics.

Hence, the correct option is A.

Define natural selection and give Example with detailed explanations.

Answers

Answer:

Natural selection is when animals who are able to survive in their environment flourish, and those animals who aren't die out.

Explanation:

Lets say there were two rival animals, we can call them plantoids 1 and 2. These plantoids were both trying to out-survive each other. The problem is birds loved to eat them, so through evolution plantoids 1 began producing toxins, so when chewed on the bird would be poisoned. For awhile this worked, and the plantoids without it were dying off. Then plantoids 2 created a thorn on their heads, and were able to blend well. This worked well, and sadly for plantoids 1 the birds were able to eat them. The birds went through natural selection and those who were immune to the poison survived. Now these two plantoids are two completely different species, and they were once the same. In the end plantoids 2 survived because they were more adapted to the setting they lived in.

What do prokaryotes have in common with eukaryotes?

A. They both have a Golgi apparatus.
B. They both have mitochondria.
C. They both have a nuclear membrane.
D. They both have a liquid cytoplasm.

Answers

Answer:

They both have a liquid cytoplasm.

Explanation:

A liquid cytoplasm is an essential part of a cell, in both prokaryotes and eukaryotes. It supports the internal components of the cell, and is the site of many vital cellular processes, such as glycolysis (the first part of cellular respiration).

The Golgi apparatus and the mitochondria are membrane-bound organelles that serve a specific purpose in eukaryotic cells. However, prokaryotic cells do not contain any membrane-bound organelles.

Prokaryotes do have a nucleus, like eukaryotes, but unlike in a eukaryotic cell, a prokaryotic nucleus is not surrounded by a nuclear membrane. Instead, it is just confined to a certain area of the cell, called a nucleoid.

Prokaryotes and eukaryotes  both have a nuclear membrane. Option C

What is the commonality?

Prokaryotes and eukaryotes are two large categories of cells with notable variations in their organization and structure. They do, however, have some things in common.

The existence of a nuclear membrane or nuclear envelope is one of the similarities between prokaryotes (such as bacteria) and eukaryotes (such as plants, animals, fungi, and protists). The cell's genetic material, which can be either DNA or RNA, is encased in the nuclear membrane. It divides the cellular components into the nucleus and the remainder.

Hypothesis: If the type of food available changes, then…

…because…

Answers

Answer: The independent variable of the lab is the type of food that is available to the birds. The food type changes in a given environment, then the amount of each type of bird beak will changes as birds with beaks more suited to the available food will consume more successfully over time.

Explanation:

With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.

What are different types of bird beaks?

There are many types of beaks in birds, some of these can be:

Crushing beak.Curved beak.Piercing and tearing beak.Birds of prey.Stickybeak.

With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.

Explanation:

The correct order of Jason's actions in the stages of the development of his group would be as mentioned above. After the first step of the formation of the group, the next step is 'storming' in which the ideas are generated. Thus, Jason asks the group members regarding their interests and hobbies as it assists in the generation of effective ideas for problem-solving. The next step would be 'norming' in which the conflicts would arise due to disagreement regarding the respective roles of group members. Then, Jason as a team member would resolve the differences among the team members to reach a common solution. After everyone agrees upon the same idea, Jason can pursue working with the group as a complete unit. These stages are crucial for the effective development of the group and achieve desired results through cooperation and teamwork.

A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: Osmosis, because energy is being used to move molecules with the concentration gradient. Active transport, because energy is being used to move molecules against the concentration gradient. Facilitated diffusion, because energy is being used to move molecules with the concentration gradient

Answers

Answer:

Active transport, because energy is being used to move molecules against the concentration gradient.

Explanation:

This picture shows active transport. That just means that energy is being used (in this case, ATP) to move molecules against their gradient (meaning, from low to high concentration). Molecules "naturally" diffuse from high-->low concentration, so to move in the opposite direction requires energy input. You can tell this because there are only 2 molecules on the top side of the membrane, but on the bottom side there are 13.

Why not A: This is not necessarily water, as in osmosis, and it's not going with the gradient.

Why not C: This is not facilitated diffusion, because molecules are going against, not with, their concentration gradient.

The description that best identifies this type of cellular transport is: Active transport, because energy is being used to move molecules against the concentration gradient.

WHAT IS ACTIVE TRANSPORT:Active transport is a type of transport that requires the input of energy in form of ATP. This is because the movement of molecules is against a concentration gradient.

According to the diagram in this question, molecules are being moved into the cell with an input of ATP (energy).

Therefore, the description that best identifies this type of cellular transport is: Active transport, because energy is being used to move molecules against the concentration gradient.

Why xylem and phloem are called complex tissues? How are they different from one another?

Answers

Answer:

Xylem and phloem are called complex tissues because they are made up of more than one type of cell working together as a unit. The xylem transports H2O and minerals upward from the roots to the leaves, and is composed of tracheid cells which are dead at maturity (no active nucleus, makes the tree stem hard). If plants don't have xylem, they will stay lower to the ground as it is responsible for making the tree grow upward. The ends of the xylem tubes are tapered (pointed), materials are passed along one cell at a time, and the tubes are narrow and continuous. The phloem transports sugars and proteins downward from the leaves to the stems and storage roots. The cells that make up the phloem are called sieve tubules and companion cells. The companion cells have the nucleus and the sieve tubules contain the cytoplasm.

Explanation:

My teacher helped us remember using the phrase "phloem down the river" because it sounds like 'flowing down the river' (to help remember that phloem transports downward and xylem transports upward.)
