Cell theory teaches us that cells are the ?
Answer:
in biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
The three tenets to the cell theory are as described below:
All living organisms are composed of one or more cells.
The cell is the basic unit of structure and organization in organisms.
Cells arise from pre-existing cells.
There is no universally accepted definition of life. Some biologists consider non-cellular entities such as viruses living organisms,[1] and thus reasonably disagree with the first tenet

What type of system is required to maintain the amount of sugar in the blood at a certain
level, making sure it does not rise too high or fall too low?
Answer:
The Digestive system.
Explanation:
Even though the Cardiovascular system pumps the blood in the body, blood sugar is dependent on the regulating hormones insulin and ketone. Which are created in the liver. And the liver is part of the Digestive system. Diabetes, hypoglycemia and hyperglycemia are results of a faulty liver.

A. ureter
B. bladder
C. urethra
D. kidney
The organ in the excretory system has a function similar to that of the esophagus in the digestive system is ureter. Thus, option A is correct.
What is urinary bladder?Urinary bladder is a temporary storage part for storing urine and it collects urine after that create sensation and than urination is controlled my motor. The capacity of urinary bladder is 400- 600 ml but it can increases as high up to 1000ml.
The urinary bladder is particularly sac like structure made up of muscle and the shape of it is like a pear. It is present in the pelvic cavity, and the bladder become empty just after urination.
The capacity of urinary bladder is 400- 600 ml but it can increases as high up to 1000ml. In order to avoid bladder infection a person must drink proper amount of water, as well as cranberry juice and he must eat probiotics and garlic in daily diet.

Which statement best describes stars?
To release energy from an ATP molecule,
a phosphate group must be added to an ATP molecule.
a phosphate group must be removed from an ATP molecule.
a glucose molecule must be broken down.
a glucose molecule must be formed.
wich one is it thank u
Answer:
To release energy from an ATP molecule, a phosphate group must be removed from an ATP molecule.
Explanation:
ATP is a molecule responsible for the storage, transport and transfer of energy necessary for metabolic reactions. It is a molecule formed by adenine, a ribose and three phosphate groups. The bonds between the phosphate groups are high-energy bonds.
When a phosphate group separates from the ATP molecule, the rupture of the linkage produces the release of energy —equivalent to 30.5 kJ/mol— which is used by the organism to fulfill its vital functions.
The other options are not correct because:
The addition of phosphate to ATP does not release energy. The breakdown of the glucose molecule consumes energy, but in the end it produces ATP. The formation of the glucose molecule is not related to the release of energy from ATP.Inversion is a type of mutation that
Answer:
the action of inverting something or the state of being inverted.
Explanation:
This type of mutation occurs a piece of DNA detaches from a chromosome during the reproductive stage and then reattaches to the chromosome in a reversed order. This will change the genetic code and make it very difficult to read.

What do plants need to survive? How do plants obtain energy?
Answer: obtain energy
Explanation:
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

How does the contractile vacuole help the paramecium survive in a freshwater environment?
The contractile vacuole helps the paramecium to survive in freshwater environments by removing the excess water and preventing cell swelling.
Vacuoles are membrane-bound organelles that are responsible for osmotic regulation or the discharge of excess water from cells.Paramecia is a group of unicellular organisms in which the excess water is removed by the pumping action of contractile vacuoles.Thus, in Paramecia, contractile vacuoles are considered to be excretory structures.In conclusion, the contractile vacuole helps the paramecium to survive in freshwater environments by removing the excess water and preventing cell swelling.

Christiaan Eijkman shared the Nobel Prize in 1929 for the discovery of vitamins. Eijkman went to Java to isolate the pathogen causing beriberi, an illness that appeared to be contagious as it was common in prisons and among ship crews. Eijkman noticed that chickens fed a diet of white rice also suffered from a similar disorder. When the chickens were fed a diet of red rice, the chickens quickly recovered. Eijkman returned to the Netherlands and persuaded a prison to feed the prisoners red rice, and the incidence of beriberi decreased. What would the next step for Eijkman be?
Answer:
See the answer below
Explanation:
The next step for Eijkman would be to hypothesize that beriberi is associated with the white rice diet and red rice has the antidote. He can then go-ahead to conduct further studies in order to test the hypotheses.
He would need to set up experiments to effectively prove his hypotheses and if found to be true, report his findings to the scientific world.

• transverse
Answer: Insertion
Explanation:
There is a letter inserted.
Original Strand : ATC CAT
Mutation Strand: ATC GCAT . The type of mutation has occurred above is the Insertion. Thus, option C is correct.
What is mutation?A mutation has been known as the changing or modification in the nucleic acid or DNA sequence of a person. This has a natural process that occurs due to mutagens.The type of the mutation that has been occurred when DNA replication occurs before meiosis is inversion.
Mutation can also be artificially induced to bring out changes in the gene sequences for specific reasons. There are different types of mutations somatic mutation occurs in the body cell and chromosomal mutation occurs in the structure of chromosome coin mutation changing the nucleotide.
In this particular insertion, there is an insert of three bases. Complementary strands in DNA are the opposite strand, so Adenine is coupled to Thymine, and Guanine is coupled to Cytosine.
Therefore, Original Strand : ATC CAT
Mutation Strand: ATC GCAT . The type of mutation has occurred above is the Insertion. Thus, option C is the correct.
