Which of the following types of models would be most effective to demonstrate the relationship between distance and time? a. idea model
b. physical model
c. computer model
d. none of the above

Answers

Answer 1

Answer: Out of the following types of models, the most effective to demonstrate the relationship between distance and time is the idea model.

Answer 2

Answer:

Answer: Option A Idea model

Explanation:

In science, a model is used to represent an idea, an object or even a process or a system and all of these are used to explain the phenomena that are difficult to be experienced directly.

There are many scientific models that are used and one of them is an idea model.

An idea model is a scientific model which is used to study relationships between variables that can either be graphed or placed into an equation.

Since time and distance are the variables that can be both plotted on a graph and placed into an equation, their relationship is represented by an idea model.

The plasma membrane has a double layer of phospholipids with _____ dispersed throughout.

Answers

To complete the sentence "The plasma membrane has a double layer of phospholipids with proteins dispersed throughout." Transport proteins move particles and particles over the layer. They can be sorted by the Transporter Classification database. Film proteins may have numerous exercises, for example, oxidoreductase, transferase or hydrolase.

Final answer:

The plasma membrane has a double layer of phospholipids with proteins dispersed throughout these layers. These proteins perform several functions, including molecule transport, enzymatic functions, and signal transduction pathways.

Explanation:

The plasma membrane of cells has a structure commonly referred to as a lipid bilayer. This bilayer consists of two layers of phospholipids. Each layer with one hydrophobic (water-fearing) end and one hydrophilic (water-loving) end. These form a double layer as the hydrophobic ends of each layer face towards each other, while the hydrophilic ends face outwards towards the aqueous environments inside and outside the cell. Proteins are dispersed throughout this lipid bilayer. These proteins serve various functions such as acting as channels or carriers for the transportation of molecules across the membrane, acting as enzymes, or functioning in signal transduction pathways or cell adhesion.

A scientist has been tracking and studying a population of deer in Yellowstone National Park. He surveys the population every six months. Usually, the population is thriving and has a gene pool with a wide variety of traits. But during one six-month period, an event occurred that affected the population, and when the scientist returned, the amount of genetic variation had decreased significantly. Which of the following is most likely the event that occurred to change the population? Yellowstone National Park expanded its borders.

Answers

Hi,

I think that you're missing some options, but here they are (let me know if I'm right!

-A population of wolves was introduced
-The amount of disease in the deer population decreased
-More grass was planted

Now, if the gene diversity decreased, it means that a lot of deer died. This could happen because wolves were introduced -this is the correct answer, and the wolves ate some deer.

It may be due to the fact that there was an event that eliminated many of the individuals in species.

What is genetic variation?

The term genetic variation refers to the occurence of organisms in a specie that are composed of different genotypes.

If the genetic variation in a population at the yellowstone park is decreased it may be due to the fact that there was an event that eliminated many of the individuals in species.

The north pole of a bar magnet is moved close to the north pole of a second bar magnet. What prediction best describes how the first magnet responds when it is released?

Answers

The best prediction that can be made to describe how the first magnet will respond when it is released is that it be repelled and move away from the second magnet. This is because similar regions of magnets repel each other, and opposite regions attract each other. This means that only the south and north regions of a magnet will experience a pull.

Answer: The answer is C It will move away from the second magnet because like poles repel.

Explanation: Like poles retract

The cell mechanism of "active transport" involves the transport of insoluble chemicals across the membrane with protein acting as the carrier.

Answers

The above statement is FALSE.

Facilitated diffusion happens when large, insoluble membrane compounds are diffused for easy transportation. However, this transport does not require energy, therefore, it is a passive transport.

Active transport requires energy when moving molecules against a concentration agent. It requires for specific membrane transport proteins. Only a certain type of protein can move a certain type of substance.

The three main types of Active Transport are:
1) Sodium-Potassium Pump
2) Endocytosis
3) Exocytosis

Answer:

Short answer-False

Explanation:

Identify all of the true statements:

A concentration gradient is the difference between
two concentrations

Active transport allows cells to transport molecules
against a concentration gradient

Diffusion results in a net overall movement from a low
concentration to a high concentration

In diffusion particles are moving around randomly in
all directions

Osmosis requires energy from respiration to be carried
out

Partially permeable membranes allow any molecules
to pass through them

Answers

Explanation:

a) True. The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse.

b) True. Active transport requires cellular energy to achieve this.

c) False. Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration.

d) True. For diffusion to work, the particles must be able to move around.

e) True. Osmosis requires energy from respiration to be carried

out.

f) False. Partially permeable membranes allow only water but not other dissolved substances to pass through.
