A heat
B. electricity
C. light
D. sound
Answer:
A
Explanation:
Because I searched it up

Explain the relationship between DNA sequence, amino acid sequence, and protein structure and function.
Answer:
The sequence of DNA may be associated with the sequence of amino acids, and the sequence of amino acids to the three-dimensional shape of the protein. It is the sequence of DNA, which provides the code for the amino acid sequence, and the sequence of amino acids further determines the protein structure that further influences the function of the protein.
When the sequence of DNA changes it causes a change in the sequence of mRNA, further resulting in the change in the sequence of DNA's nucleic acid and the sequence of amino acid. The sequence of amino acids of a protein is accountable for the composition of the protein. The composition of a protein is accountable for its function. The function and composition of a protein are primarily accountable for the organism's trait.
What can you conclude about the structure of mitochondria?
Answer:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate
Explanation:
hope that helped ;/
Answer:
Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae
List the name and functions of the major protein involved in transcription.
Answer:RNA polymerase
Explanation: adds nucleotides to form an mRNA copy from DNA by binding to a promoter sequence at the start of a gene, using the DNA template to synthesise the mRNA, and stopping at a termination sequence
The functions and names include adding nucleotides to form an RNA (RNA polymerase), binding DNA for promoting transcription (transcription factors), and stopping transcription at the termination sequence.
What is transcription?Transcription is the cellular process by which a code in the genetic material (DNA) is passed to another nucleic acid called RNA.
During gene transcription, a fragment of DNA called gene is used as a template to create a messenger RNA.Subsequently, this mRNA is then used as a template to create a protein by a process called translation.In conclusion, the functions and names include adding nucleotides to form an RNA (RNA polymerase), binding DNA for promoting transcription (transcription factors), and stopping transcription at the termination sequence.

Sea otters move into the ocean bay. The eat all the sea urchins. This change will cause the
A. Kelp to have less food
B. crabs to have less food
C. Sea ducks to have more food
D.Arctic foxes to have more food
The presence of sea otters in an ocean bay will result in a reduction in the amount of food available to carbs because they feed on sea urchins. Therefore, option (B) is correct.
What is food chain?The linear relationship between creatures that demonstrates how they obtain energy by feeding on one another is referred to as the food chain.
The information provided in this inquiry suggests that sea otters migrate into the ocean bay and consume all of the sea urchins there.
This leads one to believe that they cut down on the food supply of another eater of urchins, such as carbs. Because of this, the introduction of sea otters into the ocean bay will result in there being less food available for carbs.

In three sentences or fewer, explain the difference between using geothermal energy to generate electricity and using the geothermal gradient to heat your home with an underground heat pump.
Answer:Tapping of geothermal energy to produce electricity is done on a larger scale compared to the tapping of the geothermal gradient using a geothermal heat pump. Harnessing geothermal energy is also reliant on geological conditions such as in the area of convection boundaries while geothermal gradient can be harnessed virtually anywhere on the earth surface.
B. Energy from sources such as geothermal or from solar is used to spin the blades of the turbine. The turbine then powers a generator, which produces electricity" is the best answer but one of the most common energy inputs is wind, not solar.

Definition: This is the location where two or more bones make contact. This junction allows for
movement and structural support.
CAN SOMEONE PLZZ HELP REPORT CARDS ARE DUE TOMORROW
Answer:
Joint.
Explanation:
A joint can be defined as the location where two or more bones make contact.
Also, a ligament refers to a short elastic band-like tough fibrous tissue that holds the bones of a joint together so as to keep them in place. This joints are able to move (lengthen and shorten) as a result of the presence of muscles.
Basically, this junction known as joints are typically found in vertebrates and it allows for movement and structural support.
Hence, the ability of the human body to make movements such as sitting down, kneeling, standing up, bending, walking, running etc., is solely dependent on the joints. Thus, without joints all vertebrates would be completely rigid and static.

HURRY PLEASE I NEED A PARAGRAPH. Describe how cell membranes are selectively permeable.
Explanation:
Cell membranes are selectively permeable. Some solutes cross the membrane freely, some cross with assistance, and others do not cross at all. A few lipophilic substances move freely across the cell membrane by passive diffusion. ... Large molecules do not cross intact cell membranes, except in certain special cases.

The cells have 46 chromosomes until meiosis II is completed.
After meiosis I, the cells have 23 chromosomes.
Part of meiosis I is completed before birth.
The entire process takes about 70 days.
Answer:
After Meiosis I, the cells have 23 chromosomes
Explanation:
It is B
In meiosis there is a reductive phase (meiosis I) and the not reductive phase (meiosis II). Option B). After meiosis I, the cells have 23 chromosomes.
What is meiosis?Meiosis is a process by which, from a diploid germ cell (2n), four haploid cells (n) -the gametes, sperm and egg cells- are produced. This is the gametogenesis process.
Each daughter cell has half of the chromosomes of the original one.
There are two phases in meiosis:
the first one in which occurs a chromosome's reduction division, and the second one where the cell suffers a new division, but this one is not a reductive one.So, if the germ cell has 46 chromosomes, after meiosis I each new cell will have 23 chromosomes, because meiosis I is the reductive phase.
Option B is correct.

For the Hill Reaction, you used DCIP dye at a concentration of 1x10-4 M. Our lab technicians have stock solution at a concentration of 100mM. Explain how you would make 100mL of the DCIP for you to use in a Hill Reaction lab.
Answer:
by diluting the DCIP dye stock solution 1000 times. It can be done by diluting 0.1 ml of the DCIP dye stock solution with 99.9 ml of distilled water
Explanation:
1 millimolar (mM) = 0.001 M
1.0 × 10⁻⁴ Molar (M) = 0.0001 M = 0.1 mM
Stock solution = 100 mM = 0.1 M
100 mM DCIP dye solution diluited 1000 times >> 0.1 mM = 1 x 10⁻⁴ M
