What is the driving force for plate tectonics?


A.Gravity slab pull
B.The gravity of the Moon and Sun
C.Heat from the Earth's core causing mantle convection

Answers

Answer:

Option C

Explanation:

Driving force for plate tectonics is the "convection in the Earths mantle" or option C. Convection is the transfer of heat due to the movement in molecules also causing hot to rise and cold to sink. Convection currents cause the tectonic plates to move because the currents rise to the Earths surface forcing the plates to drive away from each other also known as seafloor spreading.

The burning and cutting of the trees will affect the carbon cycle by adding___________ to the atmosphere in the case of burning the trees and by not removing enough __________ from the atmosphere in the case of cuting the trees.

Answers

Answer:

The burning and cutting of the trees will affect the carbon cycle by adding carbon dioxide to the atmosphere, in the case of burning the trees and by not removing enough carbon dioxide from the atmosphere in the case of cuting the trees.

Explanation:

When burning and cutting down trees, these actions significantly alter the carbon cycle, adding carbon dioxide in the case of burning trees and preventing said carbon dioxide from being eliminated when cutting down the trees that, through the process of photosynthesis, are responsible for cleaning the atmosphere transforming carbon dioxide into oxygen.

Where these processes lead to carbon cycle stagnation in the short and long term.

Plants such as the Venus Flytrap and the Sun Dew attract and consume insects. These plants are unable to produce substances which break down the insect into compounds that are usable by the plant. The chemical compound that breaks down the insects is most likely * O ATP O Lipids O Enzymes O Vitamins​

Answers

Answer:

The chemical compound that breaks down the insects is most likely enzymes.

Explanation:

Venus flytraps and sundews are carnivorous- they consume insects to absorb nutrients via digestion. During absorption,  their cells take up molecules synthesized via the breakdown of macromolecules like carbohydrates and proteins. When regions of the plant come into contact with insects, these plants recognize specific macromolecules like chitin, they increase the production of digestive enzymes.

Forming digestive liquid enzymes are specialized proteins that function as biological catalysts to speed up reactions. They act on substrates, which can bind to specific regions of the enzyme, called the active site. Once bound in the presence of highly specific temperature and pH, enzymes increase the rate of a reaction over time.

Common enzymes found in their digestive secretions include chitinases, phosphatases, amylases, and proteinases.

Explanation:

Answer:

The electron transport chain can convert the energy from one glucose molecule's worth of FADH2 and NADH + H+ into as many as 34 ATP

Explanation:

The process of forming ATP from the electron transport chain is known as oxidative phosphorylation. Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed. Three ATPs are formed from each NADH + H+, and two ATPs are formed for each FADH2 in eukaryotes.

If a cell is grown in a medium containing radioactively labeled thymidine--which is one of the nucleotides needed to synthesize DNA--after the first round of replication, all of the DNA molecules will have one labeled strand and one unlabeled strand. Why? Because the radioactively labeled thymidine will be incorporated into the newly synthesized strands. If the cell undergoes ANOTHER round of replication in the same medium, the same sequence of events will occur.

What is food web?

Food web has been defined as the natural way of the interconnection of the food chain that has been represented by the help of graphs and it has been shown that in the ecological community who eats whom. The food web has been also known as the consumer consuming system. The main advantage of the food web has the organism present on the top or the organisms who belongs to the higher trophic level can provided food or feed the organisms from lower trophic level or from other food chain.

The permanent food web has been increased due to the presence of large or complex food web. There are mainly three steps in the food web or food chain and they are producers, consumers, as well as  decomposer. The producer belongs to the trophic level, the consumers belongs to the second and third trophic level, and the decomposers belongs to fourth and fifth trophic level.

Since there are more number of  species they have more oppurtunity on which ones to eat  because food webs with many species (biodiverse) are more stronger than those with few species.

Therefore, Scenarios that does not illustrate a danger bats can pose to miners is bats can attack, causing miners to contract rabies.Thus, option C is correct.

How do organisms survive if the cells they are made of continually die?​

Answers

Answer:

nope.................................

every cell in your body is over 3 billion years old.

The strategy that multicellular organisms such as humans use to project themselves into the future is to create new cell colonies from a single undifferentiated cell rather than maintaining existing colonies indefinitely. The main reason is that reproduction is more flexible and robust than maintenance, and it provides a way of starting over with a “clean slate” and slightly different genes. Complex organisms accumulate billions of errors and problems over their lifetime. So basically organisms survive because new cells are made everytime a cell dies.

Carrie conducted an experiment to see if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. She had 10 volunteers. Each of the first 5 volunteers listened to seven different music selections for 30 seconds each. The person’s pulse was taken before the music and after each 30-second interval of music was completed. The other 5 volunteers did not listen to music and had their pulse taken every 30 seconds for 5 minutes. Based on her experiment, Carrie concluded that a person’s pulse rate did change when the person listened to different types of music. Identify the control group, the experimental group, the independent variable, and the dependent variable.

Answers

Answer:

Independent variable: MUSIC

Dependent variable: PULSE

Control group: The 5 volunteers that did not listen to music.

Experimental group: The 5 volunteers that listened to seven different music selections for 30 seconds each

Explanation:

- Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment, the independent variable is DIFFERENT TYPES OF MUSIC THAT WAS PLAYED BY CARIE.

- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable being measured in an experiment. The PULSE, which was measured in this experiment, is the DEPENDENT VARIABLE.

- Control group is the group of an experiment that does not receive the experimental treatment. In this experiment, the GROUP OF 5 VOLUNTEERS THAT DID NOT LISTEN TO ANY MUSIC is the CONTROL GROUP.

- Experimental group is the group that is subjected to the experimental treatment in an experiment. In this experiment, the GROUP OF 5 VOLUNTEERS THAT LISTENED TO SEVEN DIFFERENT TYPES OF MUSIC IS THE EXPERIMENTAL GROUP.

A defensive soccer player is having trouble reacting quickly to the movements of the opposing player. How can the soccer player adjust her base of support to improve her reaction time?

Answers

Answer:

decrease the base of support and centralize her line of gravity

Explanation:

A wider base of support leads to an unsteady gait. The base of support is the contact between the feet of the soccer player and the surface (the field) supporting him. The root cause of the player's inability to react quickly to the movements of the opposing player is a lack of balance.

Balance is the ability of an individual to sustain the line of gravity which runs the center of gravity. For the player to regain his balance, she needs to decrease the base of support and centralize her line of gravity, so as to maintain balance.

Chocolate: The New Health Food Now you can stop feeling guilty about that bite of chocolate you had for dessert. Chocolate has been found to be a cause of weight gain. But scientists have discovered that it does have some health benefits. However, dont reach for that chocolate cake just yet. Researchers found that only people who ate about one ounce of dark chocolate per day received the health benefit. Dark chocolate is full of flavonoids, which help prevent diseases. Flavonoids have been found to decrease cholesterol and reduce blood clots that can cause strokes. Flavonoids also boost a natural chemical in your brain called serotonin. Low serotonin can cause depression. Thats probably why eating chocolate boosts mood and feelings of well-being. Chocolate: A Bittersweet Pill Many new studies have found that chocolate has some unexpected health benefits. But before we start calling chocolate the new wonder food, lets look at the facts. These so-called health benefits dont beat the risks of eating too much chocolate. Chocolate is rich in fats and sugar. Eating too much of it can lead to weight gain.
