How do convection currents cause the motion of tectonic plates??

Answers

Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

Answer:

These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.

Explanation:

A student wants to know what effect temperature will have on the germination rate of radish seeds.  To test this, she obtains 3 petri dishes and 60 radish seeds.  She places 20 seeds in the first petri dish and stores it at room temperature.  She places another 20 seeds in the second dish and places it in the freezer.  She places 20 seeds in the third petri dish and places the dish in an incubator.  Over the next two weeks, she waters the dishes daily and records the number of seeds germinate.  At the end of the experiment she calculates the germination rate for the seeds at each temperature. 

Hypothesis: ____________________________
Experimental Group: ____________________________
Control Group: ____________________________
Manipulated Variable (IV): ____________________________
Responding Variable (DV): ____________________________
Constants: ____________________________

Answers

Answer:

Hypothesis: IF the temperature is high, THEN the germination rate of radish seeds will increase.

Experimental Group: 20 Seeds in petri-dishes placed in the freezer and incubator each

Control Group: 20 seeds stored at room temperature

Manipulated Variable (IV): TEMPERATURE

Responding Variable (DV): GERMINATION RATE

Constants: Amount of water, same amount of time (2 weeks)

Explanation:

- The hypothesis is a testable explanation given to an observed problem. A possible hypothesis is IF the temperature is high, THEN the germination rate of radish seeds will increase.

- Independent or manipulated variable is the variable that is changed or manipulated variable in an experiment. The TEMPERATURE is the independent variable in this case.

- Dependent or responding variable is the variable that is measured in an experiment. In this case, the dependent variable is the GERMINATION RATE

- The experimental group is the group that receives the experimental treatment. In this case, the experimental group is the 20 Seeds in petri-dishes placed in the freezer and incubator each.

- The control group is the group that does not receive the experimental group. In this case, the control group is the 20 seeds stored or placed at room temperature.

- Constants are the variables that are kept unchanged throughout the experiment. In this case, the constants are Amount of water, same amount of time (2 weeks)

scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have --
A. flagella
B. hereditary material
C. Cell walls
D. Nuclear Membranes

Answers

C is correct: cell walls

Scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have cell walls. Thus, option C is correct.

What are the difference between eukaryotes and prokaryotes?

Eukaryotes are distinguished from prokaryotes in that they organelles enclosed within a nuclear membrane. The organisms of spinoloricus are radically different from other known eukaryones in that they lack mitochondria and are able to exist in the absence of oxygen. However, their genetic material is contained within a nuclear membrane and they are therefore eukaryotes rather than prokaryotes.

Taking into consideration the main characteristic of each group, prokaryote, and eukaryote. In the first case, we have that it laks nucleus and has no sexual reproduction, meanwhile, the eukaryote has organelles and has sexual reproduction. Taking this into account we can proceed to answer each part.

Therefore, Scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have cell walls. Thus, option C is correct.

I NEED HELP ASAP Sensors on a spider's legs feel the vibrations of a trapped insect and relay the information to the spider's brain through nerve electrical signals. For nerve cells to maintain these electrical potentials, sodium must be removed from the cell and potassium must be moved into the cell. Describe why this process is a form of active transport and what is required for active transport to occur?

Answers

Answer:

Please find the explanation below

- Energy (ATP) is needed for active transport to occur

Explanation:

According to this question, sensor's on a spider's legs relay information via nerve electrical signals to the brain when the vibrations of a trapped insect is felt. However, for nerve cells to maintain this electric potential, ACTIVE TRANSPORT must be carried out by removing sodium from the cell and potassium must be moved into the cell.

This is a form of ACTIVE TRANSPORT because pottasium ions are moved into the cell against concentration gradient i.e. from a region where it is in low concentration to where it is in high concentration. This active transport process is usually accompanied by the use of energy in form of ATP.

When glucose is used as an energy source, the largest amount of ATP is generated by the ___________ of the entire respiratory process.

toads entered Australia, scientists observed that the average head size in a
population of toad-eating snakes was getting smaller. Snakes with smaller
heads are not able to eat the large cane toads. What type of situation is this?
O A. Disruptive selection
B. Species richness
C. Directional selection
D. Genetic variation

Answers

The answer you are looking for is C

Natural selection is a process by which the organisms adjust to the variation in the environmental conditions so they can endure and thrive in the altered conditions.

The correct answer is:

Option C. Directional selection

This can be explained as:

Directional selection is a negative form of natural selection in which the inhabitants of one species is favoured over another.

The species with better trait characteristics will be favoured over the organism with less preferred attributes.

The allele recurrence in directional assortment shifts over time.

Therefore, toads with better traits (head size) are favoured over snakes with smaller mouth sizes.

What is the hole associated with the ozone layer ?

It is the black hole that is continuously rising and getting bigger in size though the more study about it is still unsolved.

Ozone high in Earth's atmosphere protects from the sun's dangerous radiation. But on the ground level, ozone is definitely an air pollutant that spoils people and plants.
