Answer:
Dolphins are mammals, not fish. Unlike fish, who breathe through gills, dolphins breathe air using lungs.
They don't have gills, so they can't breathe underwater like fish. They breathe through a set of nostrils on top of their heads known as a blowhole. While swimming or resting under the water, they can take breathes by exposing only the tops of their heads to the air.
Like all mammals, dolphins have lungs and breathe air. They are the organ of the respiratory system which process the air inhaled through the spiracle.

what is dendritic cells and difference between dendritic cells and glial cell
Answer:
here--->
Explanation:
Dendritic cells (DC) are the professional antigen-presenting cells of the immune system. In their quiescent and mature form, the presentation of self-antigens by DC leads to tolerance; whereas, antigen presentation by mature DC, after stimulation by pathogen-associated molecular patterns, leads to the onset of antigen-specific immunity. DC has been found in many of the major organs in mammals (e.g. skin, heart, lungs, intestines, and spleen), while the brain has long been considered devoid of DC in the absence of neuroinflammation. Consequently, microglia, the resident immune cell of the brain, has been charged with many functional attributes commonly ascribed to DC.

Which compound is inorganic?
O A C6H1206
O B. KH2PO4
OC. CH3COOH
OD. C2H6
O E. C2H5OH
Answer:
KH2PO4
Explanation:
Organic compounds generally contain carbon and hydrogen.
Inorganic compounds are formed using other elements in the periodic table.
The right response, KH2PO4, is Option B. Since KH2PO4 is an inorganic substance, it doesn't include carbon. Potassium, hydrogen, phosphorus, and oxygen atoms make up the ionic composition. It is a potassium and dihydrogen phosphate anion salt that is used as a food ingredient and fertiliser.
What are organic substances ?Contrarily, organic substances are those that have carbon and hydrogen atoms in them. The organic molecules C6H1206, CH3COOH, C2H6O, and C2H5OH are a few examples.
These substances differ from inorganic substances in that they include carbon atoms. As KH2PO4 is an inorganic chemical, Option B is the best choice for the right response. Contrarily, organic chemicals are not inorganic since they include carbon atoms.
There are two types of compounds that are organic and inorganic and these both of the molecules are possessing different types of varieties and with that varies as per the compounds and the qualities and with these different types of compounds are made.

What is immune system?The Immune System composed of different types of cells and molecules, which protect our body against pathogens.
Pathogens are defined as everything from parasites to fungi, bacteria, viruses and haptens. Haptens are molecules that may cause an immune response when they come in contact with a protein.
These cells and molecules are distributed in all the tissues of the body as well as lymphoid organs, which eliminate or prevent microbial infections to decrease the growth of tumors and start the repairing process of damaged tissues.

How many moles of LiCl are contained in 50.0 mL of 0.600 M solution?
Answer:
0.0300 moles LiCl
Explanation:
You can find the amount of moles using the molarity formula. The general structure looks like this:
Molar Concentration (M) = moles / volume (L)
You were given the molar concentration and volume in milliliters. Once you convert the volume to liters (by dividing by 1,000), substitute the values into the molarity formula. Then, you can simplify to find moles. The final answer should have 3 sig figs according to the given values.
50 mL / 1,000 = 0.0500 L
0.600 M = moles / 0.0500 L
(0.600 M) x (0.0500 L) = moles
0.0300 = moles
how are antibiotics able to target the bacteria cells but not the healthy cells within your body ?
Answer:
See below
Explanation:
Antibiotics:Medications used specifically against bacteria are called antibiotics.Difference between bacterial cells and our healthy cells:
Bacterial cells have cell walls. However, Healthy cells of our body lack cell wall.Why are antibiotics able to target bacterial cells:
Antibiotics are specific in their functions. They are designed as to attack only bacterial cells. They attack the cell wall of the bacterial cell most often. Since, the healthy cells of our body lack cell wall, antibiotics are not able to attack healthy cells of our body.In this way, our body cells are safe from the attack of antibiotics.
