27. What is the reaction for aerobic cellular respiration?
Answer:
Aerobic respiration takes place in the mitochondria and require oxygen and glucose, and produces carbon dioxide , water and energy . The chemical equation isThe sierra Nevada mountains are made from...
A Mafic igneous intrusive rock
B felsic igneous extrusive rock
C felsic igneous intrusive rock
D Mafic igneous extrusive rock
PLEASE HELP ASAPPPP
The Sierra Nevada mountains are made from felsic igneous intrusive rock, specifically granite, which is formed from slow-cooling magma beneath Earth's surface.
Explanation:The Sierra Nevada mountains are composed principally of felsic igneous intrusive rock. This felsic composition is rich in light-colored minerals such as feldspar and quartz, which indicate that the rock is granite in nature. The formation process involves magma cooling slowly beneath the Earth's surface, allowing time for larger crystals to develop, which gives the rock a coarse-grained texture. Therefore, the correct answer to which type of rock the Sierra Nevada mountains are made from is option C: felsic igneous intrusive rock.

What is a limiting factor? How can limiting factors limit the size of a population? In your answer, give an example of a biotic and abiotic limiting factor in a forest ecosystem.
Answer:
A limiating factor is what limits the poupulation in an ecosystem. For example, biotic limiting factors include food, mates, shelter. Without these things the poupulation would decrease. becuse food, mates, and shelter are limited it limits the poupulation. an example of an abiotic limiting factor is a predetor. Predetors limit the poupulation of there pray.

Andy is using a graduated cylinder to measure the volume of water. Which of the following are correct procedures for reading the volume of water in a graduated cylinder?
I.
He should hold the graduated cylinder in his hand so the surface of the water is at eye level.
II.
He should place the graduated cylinder on a flat surface and bend down so the surface of the water is at eye level.
III.
He should take the reading from the bottom of the curve of the surface of the water.
IV.
He should take the reading from the highest point of the surface of the water.
A.
II and IV only
B.
I and IV only
C.
I and III only
D.
II and III only
To measure the volume of water in a graduated cylinder, follow these steps: place the cylinder on a flat surface and read the volume from the bottom of the curved surface (meniscus).
Explanation:To measure the volume of water in a graduated cylinder, the correct procedures are:
He should place the graduated cylinder on a flat surface to ensure stability and accurate readings.
He should take the reading from the bottom of the curve of the surface of the water (the meniscus).
These procedures help to ensure accurate measurements by minimizing human errors and taking into account the meniscus, which is the curved surface of the liquid in the graduated cylinder.
deoxygenated blood obtains oxygen from the
Answer:
Lungs.
Explanation:
Deoxygenated blood contains high amount of carbondioxide while oxygenated blood has oxygen in large concentration. This carbondioxide is produced in the cell in the process of cellular respiration. This deoxygenated blood is taken from the cell to the lungs through the veins. In the lungs, the carbondioxide is removed and oxygen is loaded in the blood. This oxygenated blood is again goes to the heart and distributed to all the cells.

The greater the mass of an object, the greater its gravitational pull on
other objects around it. Which of the following exerts the greatest
gravitational pull? *
O
an asteroid
Earth
O
the Moon
O
the Sun
The greater the mass of an object, the greater its gravitational pull on other objects around it. Sun exerts the greatest gravitational pull.
What do you mean by gravitational pull?Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth's gravity is what keeps you on the ground and what causes objects to fall.
The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.
On Earth, gravity pulls all objects "downward" toward the center of the planet. According to Sir Isaac Newton's Universal Law of Gravitation, the gravitational attraction between two bodies is stronger when the masses of the objects are greater and closer together.

Cellular respiration involves a reaction between glucose and oxygen to form. A.water.
B. energy.
C. carbon dioxide.
D. all of these.
Answer: D
Explanation: THE PRODUCTS FOR cellular respiration are water CO2 AND energy
Cellular respiration involves a reaction between glucose and oxygen to form water, energy in the form of ATP (Adenosine triphosphate), and carbon dioxide. Thus, the correct option is D.
What is Cellular respiration?Cellular respiration is the process through which biological fuels are oxidized in the presence of an inorganic electron acceptor such as the oxygen atom to produce large amounts of energy, to drive the bulk production of ATP (adenosine triphosphate) in the mitochondria of cell.
In the process of cellular respiration, glucose molecules and oxygen react to form ATP molecules. Water and carbon dioxide are released as byproducts from this reaction. The three stages of aerobic cellular respiration are glycolysis, the Krebs cycle, and oxidative phosphorylation.
Therefore, the correct option is D.

Answer:
Plants alternate their generations between sporophyte and gametophyte generations.
Explanation:
Plants life cycle has two generations i. e. Sporophyte and gametophyte. Sporophyte is the first phase of plant life cycle in which spores are produced that are diploid i. e. double number of chromosomes while the second phase is gametophyte in which gametes are produced that are haploid i. e. half number of chromosome. Gametes contains sperm cells and egg cells which fuse together in the process of fertilization.

What are some of the causes that disrupt the natural balance of the ecosystem? ridding the soil of decomposers removing predators by hunting overpopulation of predators breeding hybrid plants removing prey by transplantation
Answer: overpopulation of predators
Explanation: Overpopulation of predators is the correct option. Predators are the organisms which kill other organism so as to obtain them as food. The organism being killed is called as the prey.
If the population of the predators increase this will lead to the extinction of many species of prey. As it is evident that every organism in the ecosystem has a typical role to play. Therefore, it can be said that role of prey will not be performed and this may lead to disturbance in the ecological balance.

Andreas has to make an electromagnet in his science class. He was only given a nail, copper wire, and a 9-volt battery. The assignment was to make a magnet strong enough to pick up paper clips. His teacher decided to make the assignment into a competition to see whose magnet could pick up the most clips.
What can Andreas do to his magnet to make sure he wins by picking up the most paper clips?
A
Andreas can wrap few coils of the wire, far apart, around the nail.
B
Andreas can wrap many coils of the wire, far apart, around the nail.
C
Andreas can wrap many coils of the wire, close together, around the nail.
D
Andreas can wrap few coils of the wire, close together, around the nail.
Answer:
C. Andreas can wrap many coils of the wire, close together, around the nail.
Explanation:
The ideal in this case is for Andreas to wrap the entire nail with the wire. For that he will need to use many coils of the thread. These coils should be close together, touching each other, but without overlapping, they should be next to each other. That way, Andreas's experiment will work.
If he wants to increase the magnetism power of his electromagnet, he must replace the battery with a higher voltage one.
