Which is a correct graphical representation of the organization levels of a
biological system?
Answer:
1. Biosphere
2. Ecosystem
3. Community
4. Population
Explanation:
The correct graphical representation of the organization levels of a biological system is as follows:
Cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere. What is the level of organization of the biological system?The level of the biological system may be defined as the arrangement of structures that are usually characterized by relationships with things at higher levels that are being composed of things at the next lower level. A cell is the smallest level of organization for living things while the biosphere is the highest level of organization for living things.
A cell is the basic structural and functional unit of living organisms. The collection of cells gives rise to the formation of tissues which are combindly known as organs. Organs give rise to the organ system that completely formed a living entity.
Therefore, the correct graphical representation of the organization levels of a biological system is well represented above.

ATP is an abbreviation for adenosine triphosphate, a complex molecule that contains t

that require energy.
Which statements regarding the ATP-ADP cycle are true?
ATP synthesis takes place in the mitochondria of eukaryotic cells.
The given question is incomplete as the group of choices are not given, however, the choices are associated with the question is given below:
ATP synthesis takes place in the mitochondria of eukaryotic cells.
ATP is regenerated from ADP through the process of phosphorylation.
energy is stored in the covalent bonds between phosphates, with the greatest amount of energy in the bond between the second and third phosphate groups.
most of the readily available energy stored in ATP is stored during the manufacture of adenosine.
the ribose sugar in the model above is the direct product of photosynthesis.
Answer:
The correct answer is given below:
Explanation:
ATP synthesis takes place in the mitochondria cell organelle in the eukaryotic cells, however, a small part of ATP generation takes place in other cell regions but most of the ATP synthesis is occurs in the inner membrane of mitochondria which makes it energy house of the cell.
ATP is formed by the addition of phosphorus to ADP and this process is called phosphorylation.
Each bond of the adenosine and its three phosphates has stored energy in their covalent bonds. The last two phosphates have a high amount of energy in their bond.

mendel,s experiment is applicable not only in plant but also in animals
Answer:
Yes, this is true. This is because animals also carry genes which codes for a certain trait, and these traits have their own allele. Mendel's experiment portrayed tall plants and dwarf plants being crossed, moreover the colour of the flowers could also be taken as an example. In the similar way, animals, for example, mice, could be white furred or brown furred. They both carry alleles which codes for their fur colour, like plant alleles which codes for either tall or dwarf.

D. Chewing of food
Answer:
the process of chewing food is not a chemical process bt the process of tasting the food is a chemical process
lf you find this helpful plz follow me
and mark my answer
Chewing of food is not a chemical process in the digestive system, but a mechanical process. Therefore, the correct option is D.
What is Digestive system?A collection of organs called the digestive system help break down food into smaller molecules that the body can absorb and use for energy, growth, and repair. It consists of anatomical organs such as the anus, esophagus, stomach, small and large intestine, liver, and pancreas. Food is broken down physically and chemically by the digestive system, which also absorbs nutrients and gets rid of waste.
Chemical process of digestive system involves Bile interacting with digested food in the small intestine, acids reacting with food particles in the stomach and saliva breaking down food particles while the mechanical process involves chewing of food.
Therefore, the correct option is D.

Which of the three fundamental tissues have a secondary cell well? (Parenchyma, collenchyma and sclerenchyma)
In order for high force crossbridges to form in contracting skeletal muscle, calcium must a. bind to calmodulin to phosphorylate the myosin. b. phosphorylate the tropomyosin which moves it. c. phosphorylate the troponin to move the tropomyosin. d. bind to tropomyosin which moves the troponin. e. bind to troponin which moves the tropomyosin.
Answer:
e. bind to troponin which moves the tropomyosin.
Explanation:
Troponin (Tn) is a protein complex composed of three different proteins: troponin C (TnC), troponin I (TnI), and troponin T (TnT). This complex is found both in skeletal muscles and cardiac muscles, where TnC attaches calcium ions through four and three calcium ion-binding sites, respectively. When a muscle is relaxed, Tn attaches to tropomyosin to prevent muscle contraction. During muscle contraction, calcium channels open and cytosolic calcium ions bind to TnC, thereby Tn changes its conformation and moves the tropomyosin. This process relieves the inhibition of the interaction between actin and myosin filaments, which makes muscle contraction possible.
PLEASE HELP!!! How many ATP can we get from one molecule of phosphocreatine?
a.1
b.2
c.10
d.32
Phosphocreatine is a chemical compound that provides high energy to the skeletal muscles. One molecule of phosphocreatine produces one ATP molecule. Thus, option a is correct.
What is phosphocreatine?The phosphocreatine system is a way to generate ATP and energy in the body (muscles). During muscle contraction, the phosphocreatine yields a phosphate molecule that in turn produces ATP.
The phosphocreatine system provides quick and fast energy in the form of ATP molecules through the anaerobic system that does not require oxygen. It gives its phosphate group to ADP to produce ATP as,
ADP + phosphocreatine → ATP + Creatine
The ATP-PC system yields only one molecule per phosphocreatine at a very fast rate for the muscles to utilize when doing any exercise or physical activity that involves contraction and relaxation.
Therefore, phosphocreatine produces 1 ATP.

In dolphins, to have spots on the skin is a recessive trait. One spotted dolphin and one solid gray dolphin have a baby spotted dolphin. Go through the following steps to figure out the genotype of the parent dolphins.
1) what is the genotype of the spotted (recessive) parent?
Answer:
the spotted parent has the genotype ss
Explanation:
we will use s as the letter when describing the spotted trait.
since spotted is recessive, that parents have to have two little s to have the trait. Since the child also has that, we know that they will have the genotype ss. the child would have to get a little s from both parents, so the solid parent would have Ss, showing as solid, but still having the gene for spots.

BRAINLIEST: In dolphins, to have spots on the skin is a recessive trait. One spotted dolphin and one solid gray dolphin have a baby spotted dolphin. Go through the following steps to figure out the genotype of the parent dolphins.
1) what are the POSSIBLE genotypes of the solid grey dolphin?
2) what is the genotype of the baby spotted dolphin?
Answer:
1) Ss
2) ss
Explanation:
Spots (recessive) - s
No spots (dominant) - S
So the possible combination to get a baby spotted dolphin may be: Ss and ss
Punnett Square:
| S | s |
s | Ss | ss |
s | Ss | ss |
So the genotype of the Solid gray dolphin might have been a dominant allele and a recessive allele, which is Ss.
Moreover the genotype of the spotted baby dolphin might me ss.
