A negative feedback loop is a reaction that causes a decrease in function. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

What is baseline imbalance?

This is simply known as a form of art that pertains to systematic error when producing an intervention groups in any clinical trial. In this type of imbalance, the groups differ in baseline traits due to the fact that  the participants were selected or assigned.

There are different ways to balance a load. Why is the figure considered to be an example of a negative feedback system as opposed to a positive feedback system is that The figure shows the correction of an imbalance back to a baseline.

How are the three international conflicts similar and how are they different?

Answers

Answer:

what's the question? It is not showing anything expect for "How are the three International conflicts similar and how are they different."

private sector international conflict would be a conflict between a U.S. computer company, and a Japanese company which was supplying motherboards for the U.S. company. If the Japanese company had a contract requiring them to ship 10,000 motherboards a month, but they only shipped 6,000, this would cause a private international conflict. It would not be a conflict that involved the U.S. government, but it would be one that would likely be handled in an international tribunal of some sort

How have plants evolved?
Give at least 5 examples.

Answers

Answer:

Over time, plants had to evolve from living in water to living on land. In early plants, a waxy layer called a cuticle evolved to help seal water in the plant and prevent water loss. ... To allow the plant to retain water and exchange gases, small pores (holes) in the leaves called stomata also evolved (Figure below)

Explanation:

1 DNA evidence suggests that the first eukaryotes (green plants) evolved from prokaryotes (through endosymbiotic events) between 2500 and 1000 million years ago. ... Cyanobacteria have a close evolutionary relationship with eukaryotes. They have the same photosynthetic pigments as the chloroplasts of algae and land plants.

2Plants adapt their growth, including key steps in their life cycle such as germination and flowering, to take advantage of environmental conditions. ... All land plants evolved from an aquatic ancestor, and it was after colonisation of the land that the gibberellin mechanism evolved.

3 700 million years ago

The researchers found that land plants had evolved on Earth by about 700 million years ago and land fungi by about 1,300 million years ago — much earlier than previous estimates of around 480 million years ago, which were based on the earliest fossils of those organisms.

4 The earliest trees were tree ferns, horsetails and lycophytes, which grew in forests in the Carboniferous period. The first tree may have been Wattieza, fossils of which have been found in New York State in 2007 dating back to the Middle Devonian (about 385 million years ago).

5 Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.

The area of the cell that is associated with the production of ribosomes is the:
1. nucleolus
2. nucleus
3. nuclear pores

Answers

Answer:

Nucleolus

Explanation:

This is a more technical answer. The Nucleolus is located inside the nucleus and this is the location where the ribosomes are produced. They then leave through the nuclear pores to be sent out into the cell.

The area of the cell that is linked with production of ribosomes is nucleolus. The correct option is 1.

What is nucleolus?

The nucleolus is a circular shape within the nucleus of cells that produces and assembles the cell's ribosomes. Ribosomal RNA genes are also transcribed in the nucleolus.

The nucleolus has the most visible realm in the nucleus of a eukaryotic cell, and its basic task is ribosomal RNA (rRNA) melding and ribosome biogenesis.

The nucleolus, as the site of ribosome biogenesis, is critical to cell metabolic activity.

It is made up of ribosomal DNA (rDNA), which is found in tandem arrays in nucleolus event coordinator regions.

The nucleolus synthesizes ribosomal subunits from proteins and ribosomal RNA, or rRNA.

It then starts sending the subunits to the rest of the cell, where they join together to form complete ribosomes.

Thus, the correct option is 1.

TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)​

Answers

Answer:

False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.

Explanation:

Hope this helps.

It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.

What is nuclear envelope made of?

The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.

In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.

The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).

Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.

Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.

Thus, the given statement is true.
