Answer:
1)sunlight and co2
2)oxygen and ?
Explanation:
the age of fossils can sometimes be determined by radiometric dating, which is based on the constant rate of decay of radioactive isotopes. the time required for half of a radioactive isotope to decay is called the half-life of that isotope. for example, the isotope carbon-14 has a half-life of 5,730 years.
Answer:
17,190 years Radiometric dating is a technique for determining the age of fossils that is based on the fact that specific radioactive isotopes decay at a constant rate.

The best advantage of sexual reproduction is?
It is more efficient than asexual reproduction
It is safer than asexual reproduction
It results in identical offspring
It increase genetic diversity through meiosis, crossing over, and random assortment of chromosomes
Answer:
it increase the genetic diversity through meiosis , crossing over and random assortment of chromosome
Explanation:
There are two main processes during sexual reproduction: meiosis, involving the halving of the number of chromosomes, and fertilization, involving the fusion of two gametes and the restoration of the original number of chromosomes.
while asexual reproduction doesn't form any reproduction that involves neither meiosis nor fusion of gametes
A goniometer measures __________. A. A joint's maximum range of motion B. A joint's minimum range of motion C. A joint's flexion D. Extension and hyperextension Please select the best answer from the choices provided. A B C D.
A goniometer measures __________..
Answer : A
Explanation : A joint's maximum range of motion
Hope this helps you!
Answer:
A. a joint's maximum range of motion
Explanation:
A goniometer is a device that is used to measure the maximum arc of motion made by a joint. The traditional goniometer consists of a protractor and two extending arms ,one of the arms is movable while the other one is stationary.To take measurements the center of the goniometer is aligned with the center of a joint. Then the arm of the goniometer is moved until it aligns with the limb that has been moved to a maximum position that the joint allows. The angle made between the two arms of the goniometer is measured in degrees and is the maximum range of motion of the joint.

while a neuron membrane is depolarizing its __________.
Given what we know about the depolarization of neurons, we can confirm that while a neuron membrane is depolarizing its sodium gates are fully open.
Throughout the human body, sodium is often used to cause shifts in membrane potentials, as well as a variety of other metabolic processes, due to the electric charge of this ion. One such example is the neuron, which uses a flood of sodium ions to depolarize its membrane.
During depolarization, the membrane potential changes from a negative charge to that of a positive one. This is caused by the rapid flooding of sodium into the cell, which increases the positive charge in the interior of the cell and thus affects the membrane's potential.

Answer:
hydrolysis
Explanation:
hydrolysis is the reverse of dehydration because it breaks a covenant bond by adding a water molecule
hope this was helpful ☆☆
In translation, the dehydration synthesis reaction is catalyzed by DNA polymerase enzyme. Therefore, the correct option is B.
What is DNA polymerase?DNA polymerases are a group of enzymes that are responsible for catalyzing the synthesis of DNA. Their main function is to replicate the DNA. These enzymes work in pairs and a responsible for replicating two strands of DNA in a tandem. DNA polymerases α and δ are primarily responsible for nuclear DNA replication. There are at least 15 DNA polymerases known to exist in humans.
Translation is the process by which the genetic code carried by mRNA is decoded to produce a specific sequence of amino acids that will form a protein. This process involves the ribosome, which is responsible for assembling the protein chain by joining amino acids in a specific order dictated by the mRNA sequence. Therefore, the correct option is B.
