What are proteins?
Protein is found throughout the body in muscle, bone, skin, hair, and virtually every other body part or tissue. It makes up the enzymes that power many chemical reactions and the hemoglobin which carries oxygen in your blood. At least 10,000 different proteins make up the human being.
Protein is made from twenty-plus basic building blocks called amino acids. Because body does not store amino acids, our bodies make them in two different ways: either from scratch, or by modifying others. Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are known as the essential amino acids, and must come from food.

Explain how the nucleus Observed in cheek cell
Answer:
The nucleus at the central part of the cheek cell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope.
Copied
Answer:
The cell has different parts, and those that can absorb stains or dyes are referred to as chromatic. Having absorbed the stain, these parts of the cell become more visible under the microscope and can therefore be easily distinguished from other parts of the same cell.
Without stains, cells would appear to be almost transparent, making it difficult to differentiate its parts.
Explanation:Methylene blue has a string affinity for both DNA and RNA. When it comes in contact with the two, a darker stain is produced and can be viewed under the microscope

Using technology in the field of agriculture which has enabled farmers to feed a growing human population is an example of a beneficial use of technology.
Answer:
This statement is true
Explanation:
Technologies associated with agriculture systems have greatly enhanced crop yields around the world. An example of this is the "Green revolution" in 1950-1960, where the combination of genetic improvement methodologies with the use of fertilizers was critical for the amazing increase in crop yields, particularly in new varieties of rice and wheat. Indeed, the agronomist who developed some of these high yielding varieties of wheat, Norman Borlaug, was awarded the Nobel Peace Prize for his contribution to the extensive increase in crop production, thereby helping to alleviate world hunger.
Which statement best describes the movement of carbon dioxide into or out
of a plant during photosynthesis?
The correct answer is C. It is taken in from the air
Explanation:
Carbon dioxide is a gas that exists mainly in the air or atmosphere. Additionally, this chemical compound is required for plants as part of photosynthesis (process to produce energy). In this process, plants take dioxide from the air through the leaves' stomata, which are small spores, use this along with sunlight and water to produce energy, and later release oxygen. According to this, carbon dioxide is taken from the air by plants (option C) while oxygen is given off.

1. microevolution
2. macroevolution
3. genetic divergence
Answer:
2. macroevolution
Explanation:
Macroevolution refers to the evolutionary processes that lead to the appearance/extinction of groups larger than individual species. Macroevolutionary processes include speciation, species selection and punctuated equilibrium. The punctuated equilibrium processes are represented by phenomena such as those cases described above. These evolutionary processes are concentrated in relatively short speciation phases caused by bursts of evolutionary changes, which are then followed by stages characterized by evolutionary stasis.

A molecule composed of amino acids joined together. It contains nitrogen in addition to CHO
Answer:
This question describes a PROTEIN
Explanation:
Proteins are one of the four biological molecules in living systems. It is a biological polymer composed of monomeric units called amino acids, which are chemically joined together by peptide bonds.
An amino acid structurally consists of a central carbon atom bonded to an hydrogen atom, carboxylic acid group (-COOH), an amine group (-NH2) and a R side chain, which distinguishes one amino acid from another. Since all amino acids have a nitrogen-containing amine group, all proteins also contains nitrogen in their structure. Hence, a protein consist of an hydrocarbon (CHO) with a nitrogen atom.
does sexual selection result in organisms becoming optimally adapted to their environments? Explain your reasoning
Answer:
yes, sexual reproduction leads to the selection of better individuals for a particular environment
Explanation:
Natural selection can be defined as a mechanism associated with the survival and reproduction of individuals better adapted to their environment. Sexual reproduction is able to increase genetic variation, which is the primary source on which natural selection works. In consequence, individuals that exhibit an evolutionary adaptive phenotypic variant will have more chance to survive and to reproduce than those individuals with other less adaptive traits, thereby leading to evolution of the population and tending to optimize phenotypic variants for particular environmental conditions.

Fibronectin
-It can bind to fibrin which is important in blood clotting, and fibronectin can attach to heparin sulfate proteoglycans or collagen for binding it to the Extra Cellular Matrix.
-The RDG-containing cell-binding domain of fibronectin is very important for permitting cells to bind to this molecule, due to the fact that it is site that is attach by integrins on the surface of the cell.
Laminin
-A collagen IV binding site permits it to bind to the basal laminae (the molecule is predominantly found at this site).
-_6_1 integrins specific integral-binding site

Which morphological difference is associated with C4 plants but not C3 plants?
A. Stomata in the lower epidermis
B. Spongy mesophyll cells
C. Xylem
D. A waxy coating of the bundle sheath
Answer:
Explanation:Answer:
D. A waxy coating of the bundle sheath
Explanation:
C3 plants are plant that make use of Calvin cycle for synthesising their food while C4 plants makes use of Calvin cycle along side a 4 carbon compound that help store carbondioxide.
The C4 plant is unique because it has both mesophyll cell and bundle sheath unlike C3 plant that has only the mesophyll cell. The bundle sheath is where the 4 carbon compound that ferried carbondioxide is first stored before in form of oxaloacetate before broken down cell into pyruvate and carbondioxide and now proceed into the Calvin cycle for the formation of sugar in the bundle sheat.
The bundle sheat and mesophyll cell help separate when carbondioxide is ferried in and when it is used up for sugar formation in C4 plants.
A store sells a variety of sets for building molecular models. The sets are described by the diagram below. Each circled letter represents a box of 6 model atoms of one element. For example, the circled letter "P" represents a box with 6 model phosphorous atoms.
Set 1 has 12 carbon, 12 oxygen, and 18 hydrogen atoms. Set 2 has 12 carbon, 12 oxygen, and 24 hydrogen atoms. Set 3 has 6 carbon, 12 oxygen, 12 hydrogen, 6 nitrogen, and 6 phosphorous atoms. Set 4 has 6 carbon, 6 oxygen, 6 hydrogen, and 6 phosphorous atoms.
Kendra wishes to build a model of a carbohydrate molecule, ideally containing as many monomers as possible. Which set should she choose?
A. Set 1
B. Set 2
C. Set 3
D. Set 4
Answer:
B. Set 2
Explanation:
Carbohydrate is one of the four biological molecules in living systems (others are proteins, lipids and nucleic acid). The carbohydrate molecule consists of a long chain of carbon, hydrogen and oxygen elements in a ratio 1:2:1. Hence, the simplest unit of a carbohydrate has an empirical formula of (CH2O)n where n is the number of chains.
According to the question, a store sells a variety of sets for building molecular models and Kendra wishes to build a model of a carbohydrate molecule. Since carbohydrate monomers have a CH2O formula, Kendra needs a set in which the ratio of carbon: hydrogen: oxygen is 1:2:1. SET 2 fits this description by containing 12 carbon, 12 oxygen, and 24 hydrogen atoms
That is, carbon (12/12) : hydrogen (24/12) : oxygen (12/12), which is 1:2:1. Therefore, SET 2 is the best choice for Kendra in order to build her model of carbohydrate molecule containing as many monomers as possible.
