What cellular processes (2) are "hijacked" by the virus?

Answers

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. During the stage known as translation, this genetic material is used to produce the proteins that will form the capsid.

1. Uniformitarianism.

2. Weathering

3. Erosion.

Explanation:

1. Uniformitarianism: The present is the key to the past. It is a theory which states that the natural processes and laws that are being experienced in the present have been operating in the past and as such applies to everything in the universe.

2. Weathering: the breakdown of rocks into sediments. Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;

I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.

II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

3. Erosion: the process of transporting sediment to a new location. Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.

Generally, the steepness of a body affects the rate at which other materials would flow or move around. Thus, the steeper a river or stream, the greater would be its rate of erosion.

Why would it be difficult for plan animal cells to make cell energy if there wasn't sunlight

Answers

It would be more difficult for plant cells because they wouldn’t be able to perform photosynthesis. Without photosynthesis, plants cannot make glucose (energy). Animals can get energy by eating other organisms (food).

how does structure of dna relate to the process of replication and protein synthesis?

Answers

Hello Sophia,
The structure of DNA relates to the process of replication and protein synthesis actually in many ways. DNA is a nucleus acid, one of the 4 major macromolecules (polymers). It provides the instructions for making proteins. When DNA replicates, one strand is used as a template for DNA polymerase to joint corresponding nitrogenous bases. Small, individual sections of the DNA are called genes, which code for a specific protein. STRUCTURE ALWAYS DETERMINES FUNCTION! Thus, DNA tells the cells which amino acids (building blocks of proteins) and in what order for the ribosomes (found in the cytoplasm) to synthesize. These proteins then determine our traits and characteristics. It may be more than you need, but hopefully it helps somewhat. Great question, though! Biology is so interesting, when you think about it! It makes our world and our selves.

The diagram below illustrates a natural Earth process through which the atmosphere
traps heat. Many scientists hypothesize that human activities are accelerating this
process, resulting in a global warming trend. What human activity is believed to have an
adverse effect on the natural process pictured here?

Answers

Answer: c. burning of fossil fuels.

Explanation:

Carbon Dioxide and other greenhouse gases like it are the reason some of the sun's heat is trapped in the atmosphere instead of leaving back into space. Any process which increase the amount of carbon dioxide in the atmosphere therefore can increase global warming.

One of the major human activities that involves releasing carbon dioxide is the burning of fossil fuels. We use fossil fuels for many things including producing electricity and driving. When this happens we release a lot of carbon dioxide into the atmosphere thereby making global warming worse.

Sedimentary rocks can be made of particles from which of the following?
-Sedimentary
-Metamorphic
-Igneous
-all of the above.

Answers

All of the above.

Sedimentary elements are made up of broken down particles from many different substances. Sedimentary rock forms when multiple particles lump together to make a larger particle until it becomes highly visible and large. For example,

The Mississippi River carries sediment from upstream (typically soil from the dryer parts of the USA) and that sediment gathers into levee's which help protect the coast of Louisiana and the Gulf of Mexico.

Answer:

Nondisjunction (during meiosis in gametogenesis)

Explanation:

This is meiosis because we can see germ cells present, and the chromosome number is halved (typically) by the end of the process. This is nondisjunction because the sister chromatids/chromosomes are failing to separate properly during cytokinesis, causing improper amount of chromosomes in the germ cells. So on the left you have nondisjunction during meiosis II, because you have two cells with the proper amount of chromosomes after the first division. And on the right you have nondisjunction during meiosis I, because you have one cell with no chromosomes after the first division. The steps are as follows: 1 - Meiosis, 2 - Meiosis II, 3 - Fertilization, and 4 - Zygote (creation of).

How are photosynthesis and cellular respiration related?

A. The products of photosynthesis are the reactants of cellular
respiration

B. Cellular respiration is the process animals use to produce glucose,
while photosynthesis is the process plants use to produce
glucose.

C. Photosynthesis produces water molecules, while cellular
respiration splits water molecules apart.

D. Cellular respiration provides the energy for photosynthesis.

Answers

Answer:

I would say your answer for this question would be Option D: Cellular respiration provides the energy for photosynthesis.

Explanation:

Photosynthesis is  the process by which plants use the energy from sunlight, carbon dioxide, and water and convert them into food, and Cellular resipration is the process by which organisms use oxygen to break down glucose and convert it to usable energy. That means that Option B can be crossed out, along with Option C. In Option A, the products of photosynthesis are not the reactants of cellular respiration, but rather the user of the energy that Cellular respiration provides. That means you can cross out Option A, and now you are left with Option D as your answer.

Answer:

A. The products of photosynthesis are the reactans of cellular respiration
