What is a feedback mechanism?

Answers

Answer 1
Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself

Answers

Answer:

Weather is the day-to-day conditions, and climate is the conditions expected over relatively long periods of time.

Explanation:

The difference between weather and climate is how long the period of time they refer to is.

Weather is what conditions of the atmosphere are over a short period of time, or day-to-day conditions. It's what we see on the weather forecast every day - whether it's going to be sunny or rainy today and tomorrow and similar.

Climate is what conditions of the atmosphere are over longer periods of time, usually 30 years. In fact, it's an average pattern of weather for a particular region. A description of a region's climate will include the precipitation, temperature, humidity, sunshine, wind velocity, phenomena such as fog, frost, and hail storms, and similar conditions.

Why were some of Schwann and Schleiden’s ideas about cells incorrect

Answers

Answer:

One of Schwann and Schleiden’s ideas was that cells were originated by spontaneous generation, which was later rejected by Virchow.

Explanation:

Schwann studied animal tissues, and by observing them, he concluded that tissues were made of cells.

Simultaneously, Schleiden arrives at the same conclusion when studying vegetable tissues.

Around 1830, they met and together proposed the first cell theory. The theory stated that:

Every living being is made of cells.Cell is the basic unit of life. Cells are originated by spontaneous generation.

Virchow, who studied human tissues, during his observations sow the cell in its dividing process. He then proposed that cells were not originated from spontaneous generation, but they were the product of other pre-existing cells and were originated by cellular division. He rejected the third state of Schwann and Schleiden’s ideas.

What is a major difference between DNA replication and DNA transcription?

Answers

Answer:

RNA molecules produced by transcription are much shorter in length than DNA molecules produced by replication.

Explanation:

In DNA transcription, only a segment of DNA is copied, or "transcribed," to a complementary strand of messenger RNA.

In DNA replication, the entire length of the DNA molecule is copied so that it can be passed to a new cell.

State the term used to describe an enzyme that functions within a cell.

Answers

Answer:

Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism

Explanation:

An intracellular enzymes can be referred to as endocyto enzymes. These are intracellular proteins that accomplish their function within the same cell that synthesized them. They can be either free in the cytosol or associated with an organelle -inside the organelle or fixated to it-.

--------------------------------------------

Enzymes are catalytic intracellular molecules or polypeptides that accelerate different natural chemical reactions. They have specific binding sites to substrate molecules and turn them into product molecules.

Enzymes are in charge of catalyzing cell metabolism. Since they are proteins, they share many properties with all polypeptides. One of these is that they have a limited temperature level at which they denaturalize.

According to the place where they accomplish their function, enzymes can be called

Plasm-specific enzymes ⇒ Their action field is the plasma ⇒ These are exportation proteins.Secreted or Exocyto enzymes ⇒ Their action field are tissues placed far away from where they were produced and released (for instance, the pancreas secretes and releases enzymes that accomplish their function in the duodene) ⇒ These are exportation proteins.Intracellular or Endocyto enzymes ⇒ All enzymes that accomplish their function within the same cell that synthesizes them ⇒ These are intracellular proteins.

Within the cell, enzymes can be free in the cytosol, or fixated to an organelle.

Uniloculated enzymes ⇒ 100% cytosolic enzymes.Biloculated enzymes ⇒ They spend part of the time in the cytosol and  part in organelles.

Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen? A. The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle. B. The energy flow—and thus oxygen flow—for cellular respiration and photosynthesis take place in the same direction, and therefore build upon one another. C. Cellular respiration is a process that releases energy and oxygen, while photosynthesis withdraws energy and uses oxygen, therefore keeping each process in balance. D. Oxygen readily accepts electrons, so cellular respiration uses a negligible amount of oxygen.

A student was asked to compare a cell to a typical home. In this analogy, the cell mitochondria are like the (floor,furnace,or roof) and the cell membrane is like the (walls,doors and windows,oven orattic or garage)

Answers

Answer:

um...

If A Plant Cell Were A House...

Cytoplasm

Vacuole

The Cytoplasm

would be the carpeting. The Cytoplasm is the goo that all the organelles reside in, and all the furniture and stuff in the house kind of sit there in the carpeting.

The vacuole would

be the closets and pantries. The vacuole holds random things that the cell needs, and closets and pantries can hold anything you feel like putting in them, like food or clothes.

Lysosome

Mitochondrion

The mitochondrion would be the kitchen. It produces energy for the cell to use, and the kitchen produces food, energy for humans.

Nucleus

Endoplasmic Reticulum

Rough

The nucleus would be my mom. The nucleus controls the cell, and my mom controls my house.

Ribosomes

The Smooth ER would be just plain hallways. The ER is a vast network of tubing that things the cell needs travel down.

The Rough ER would be hallways filled with cattle. This wouldn't be a very good example, because it isn't a very vast network. A lot of people travel down them, though! The Rough ER is like smooth, except with ribosomes.

If you had a herd of cattle in your yard, it would be them. If not, just the kitchen, like the Mitochondrion. Ribosomes synthesize proteins, and cattle make milk, which is full of protein. Also, in the kitchen you can make proteins with different types of dairy, like cheese or milk.

Smooth

Lysosome

Golgi (apparatus)

The Lysosome would be the trashcans, the recycle, and the compost. The Lysosome kills bacteria and holds it in plus other waste, and we dispose of our waste by putting it in one of the above options.

The Golgi (apparatus) would be my dad. The Golgi sorts and packages macromolecules to get them ready to transport. My dad does the same sort of thing, he's in charge of kind of organizing/sorting things around the house.

Cell Membrane

The Cell Membrane would be

the doors and the screens (on the windows). The cell membrane is a semi-permeable barrier, meaning that some things can get through and some can't. For example, only people who have the right key can open the door. Also, with the screens, air can get in, but flies and bees can't.

Chloroplast

Cell Wall

The Chloroplasts would be solar panels, if you had any, or houseplants if not. The Chloroplasts convert sunlight into energy, and both houseplants and solar panels do this same job.

If a cell were a house,

the walls, floors, and ceiling would be the cell wall because they keep everything in the house inside, just like the cell wall keeps all the organelles inside the cell.

A new microorganism is isolated from a lake and is placed into a solution of KCl. The voltage difference across its membrane is measured at 120 mV. How much energy is required to move a proton from the negative side of the membrane to the positive side?

Answers

Answer: [tex]\Delta U=[/tex] 1.922x10⁻²⁰ Joules

Explanation: Electric Potential Energy (U) is the energy a charged object has due to its location in an electric field and it will only exist with the object is charged.

Voltage or Electric Potential Difference (V) is external work done to move a charge from one point to another in a electric field.

These terms have a relationship, which is given by:

[tex]\Delta U=q\Delta V[/tex]

where

q is the charge

Proton is positive and has a charge of 1.6x10⁻¹⁹C.

Unit for potential energy is Joule (J). The relation between mV and J is

1mV = 10⁻³J

Then:

V = 120x10⁻³

V = 0.12

So, for a proton to move from the negative side of a membrane to the positive:

[tex]\Delta U=q\Delta V[/tex]

[tex]\Delta U=1.6.10^{-19}.0.12[/tex]

[tex]\Delta U[/tex] = 1.922 x 10⁻²⁰

Energy necessary to transport a proton from negative side of the membrane to the positive is 1.922 x 10⁻²⁰J.

Answers

Answer:

B. tires are to a car.

Explanation:

Ribosomes are to Rough Endoplasmic Reticulum as tires are to a car. So the correct option is B.

What are ribosomes?

The biological machinery that produces proteins is called a ribosome. Each cell has several ribosomes, which are each composed of two subunits. These two subunits form a tight seal around the messenger RNA molecule before moving down its length and reading each three-letter codon.

The transfer RNA, whose base sequence matches that of the messenger RNA, docks to the ribosome. A specific amino acid can be added to the end of the expanding protein chain by pairing each three-letter messenger RNA codon with the corresponding anticodon on a particular transfer RNA. Once the protein is finished, the ribosome fragments.

The process of making proteins in a cell takes place at an intercellular structure called a ribosome, which is formed of both RNA and protein. The messenger RNA (mRNA) sequence is read by the ribosome, which then converts the genetic code into a specific string of amino acids that develop into extended chains and fold to create proteins.

Therefore the correct option is B.
