Answer:
The molecule is a protein
Explanation:
When the molecule was tested with benedict's solution and a blue color was formed, that actually meant there was no colour change because the colour of benedict's solution is blue. Benedict's solution is used to test for the presence of reducing sugar, which changes it's colour to green, orange, yellow or even red; the fact that there was no colour change shows the molecule is not a reducing sugar.
Yellow colour when tested with IKI (Iodine-potassium iodide) also shows no colour change. IKI reagent is used to determine the presence of starch, which gives off a dark-blue colour if starch is present. Hence, absence of this dark-blue colour or observation of a yellow/orange colour shows the molecules is not starch.
Biuret reagent is used to test for peptide bonds in a molecule. In the presence of a peptide bond, the biuret reagent changes colour from blue to violet. The amino acids in proteins are held together by peptide bond, hence the biuret colour change shows that the biomolecule is a protein.
While you were on safari, your friend got bit on the leg by a posionous snake and nearly died from excessive hemolysis. Being a true scientist, you captured the snake and analyzed its venom to understand why it caused hemolysis. You found thwo enzymes, a protease (breaks down proteins), and a phospholipase. He isolated each of these enzymes and treated red blood cells with them. He found that only phospholipase caused red blood cell lysis. He also found that, after treatment of red blood cells with the phospolipase, there was excess amounts of free phosphophorylcholine (Choline phosphate group) and free diacylglycerol (glycerol with two hydrocarbon tails). 1.) What is the substrate for phospholipase and where does it cleave
Answer:
Phospholipase is an enzyme, which is classified into phospholipase A2 and phospholipase A1.
In this case we are talking about phospholipase A2, that is why the sn-2 ester bond of glycerophospholipids will be taken as a substrate, giving fatty acids as a product, such as arachidonic acid.
Explanation:
The glycerophospholipids used by this enzyme are those found in cell membranes, these pathways are usually associated with inflammation pathways for the formation of arachidonic acid that functions as an immunological mediator.
On the other hand, it must be remembered that membrane phospholipids are amphipathic, that is, with hydrophilic and hydrophobic molecules and are responsible for balancing the internal homeostasis of the intracellular environment.

What challenges cell biologists face in the 21st century?
Answer:
There are many types of challenges are faced by the scientists in 21st century. some are as given below:
Explanation:
1. Getting biodiversity. We're losing species at a disturbing rate, and we have to comprehend what the implications of that may be.
2. sustainable development. Like feasible agriculture, yet more broad sense. Discovering approaches to accommodate human needs while limiting the mischief we cause to the earth is urgent.
3. Everything about hereditary qualities. It's simply so much fun.
4. The most effective method to cut across political, social, and social limits and spur enormous and little scope activity to lessen biodiversity loss. This point may have a hefty sociology component, yet it's significant. All the natural and biological information on the planet won't make any difference on the off chance that we can't get individuals to follow up on it.

what is cell theory ?Cell theory is widely accepted view of origin of life on Earth functions, all organisms are made of either single cells or a group of cell create tissues, organs, and organisms.
Three major hypothesis of cell theory are all organisms are made of cells, Second, cells are the building blocks in the creation of tissues, organs, and entire functioning organisms. The third is the cells can only arise from other cells or pre-existing cells.
Two scientists called Theodor Schwann and Matthias Jakob Schleiden first developed the cell theory in the year of 1839, along with Rudolf Virchow another scientist who contributed to the theory.
Schleiden explained that the structural part of a plant was made up of cells and a crystallization process either within other cells or from the outside cells. Theodor Schwann explained that the structures of animals are composed of cells.
The modern cell theory explained some postulates like All living things are composed of one or more cells, arise from pre-existing cells by cell division, fundamental unit of both structure and function in living organisms.
The activity of an organism is the activity of independent cells, Energy flow observed within cells, contain genetic material like DNA and RNA in cell nucleus and cytoplasm.

[tex]\huge\bold\red{Answer:-}[/tex]
The dental formula represents the arrangement of teeth in each half of the upper and the lower jaw. The entire formula is multiplied by two to represent the total number of teeth.
The dental formula for milk teeth in humans is:
[tex] \frac{2102}{2102} = 2[/tex]
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, and 2 molars. Premolars are absent in milk teeth hence the zero.
The dental formula for permanent teeth in humans is:
[tex] \frac{2123}{2123} = 32[/tex]
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, 2 premolars, and 3 molars. An adult human has 32 permanent teeth.

. Name the cells that are produced by the testes and ovaries.
Answer and explanation:
In the female of the species the reproductive cells are the egg cells, and in the male the reproductive cells are the sperm. The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells. The testes contain germ cells that differentiate into mature spermatozoa, supporting cells called Sertoli cells, and testosterone-producing cells called Leydig (interstitial) cells.

Which two processes allow water to enter the atmosphere?
evaporation and transpiration
precipitation and condensation
condensation and evaporation
transpiration and precipitation
Answer:
its c) condensation and evaporation
Explanation:
Evaporation and transpiration are the two processes that allow water to enter the atmosphere. The correct option is A.
What is transpiration?Transpiration is the method by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and water from the stem and roots moves upwards or is started to pull into the leaves.
The direct impact of transpiration is that it regulates plant temperature and provides water for photosynthesis. It also transports nutrients and sugars through the plant's vascular tissues.
Evaporation is a way of vaporization that occurs on the surface of a liquid as it transitions from the liquid phase to the gas phase.
Both of these process aids to enter water into the atmosphere.
Thus, the correct option is A.

Answer:
The correct answer is "Orthologs are homologs found in the same species".
Explanation:
Orthologs, or orthologous genes, are defined as genes found in different species that evolved from a common ancestry. Therefore, It is false to affirm that orthologs are homologs found in the same species. Orthologous genes have the same function and often share common nucleotide sequences, however, they must be found in different species to be considered orthologs.

By what factor (how much) does the milli- unit differ from the centi- unit?
earth science
Answer:
By a factor of 0.1.
Explanation:
Hello,
In this case, since the milli- unit has a factor 0.001 and the centi- unit a factor of 0.01 we can apply the following division in order to compute by what factor they actually differ from:
[tex]\frac{milli}{centi}= \frac{0.001}{0.01} =0.1[/tex]
It means that the milli- unit differ from the centi- unit by a factor of 0.1. Conversely, the centi- unit differ from the milli- unit by a factor of 10:
[tex]\frac{centi}{milli}= \frac{0.01}{0.001} =10[/tex]
