Answer:

The HYPOTHESIS

Explanation:

In an experiment, the formulation of the hypothesis is a critical part of the scientific method. The hypothesis is testable explanation given after making an observation in an experiment. In other words, an hypothesis is a predictive statement given that is subject to testing via experimentation.

The essence of formulating an hypothesis is to relate the effect of a possible solution on an observed problem. The "hypothesis" section of a laboratory report is usually identified by the use of an IF and THEN phrases in the statement. IF represents the cause, while THEN represents the effect. For example, a hypothesis can read; If plants are placed under white light (cause), then they will grow faster in height (effect).

Explanation:

Many species in Archaea actually require extreme temperatures and conditions to grow

The domain that contains organisms that are adapted to live in harsh environments is the domain Archaea. The correct option is B).

Any single-celled prokaryotic organism without a definite nucleus is referred to as an archaea, and they differ from bacteria in a number of important ways at the molecular level.

Archaea have membranes that are formed of branching hydrocarbon chains, many of which also contain rings, connected to glycerol via ether bonds, as opposed to bacteria and eukaryotes.

The microorganisms in the archaea domain are not typical of natural habitats. Instead, they can be found in severe and extreme environments like hot springs, salty environments, acidic conditions, etc.

Therefore, the correct option is B) domain Archaea.

Explanation:

Answer:

80 mm Hg

Explanation:

Immediately prior to ventricular systole, pressure in the aorta is about 80 mm Hg. This can be explained by the Frank-Starling Law which states that the stroke volume of the left ventricle will increase as the left ventricular volume increases due to the myocyte stretch which tends to cause a more forceful systolic contraction. This applies in the case that all of the other factors remain the same during that time.

Coevolution  

Explanation:

Just took the test and got it right

hopefully this helps you :)

pls mark me as as brainlest

The example of flowers evolving to produce ultraviolet markers on their petal in response to the ability to see ultraviolet radiation in honeybees is that of coevolution.

According to a definition, coevolution refers to reciprocal changes in 2 or more living organisms that are involved in some forms of interactions.

In other words, it is the development of certain characteristics by one organism in response to characteristics developed by another based on the fact that the two organisms interact in some ways.

In the illustration, some flowering plants depend on honeybees for pollination. Thus, as the honeybees developed the ability to see ultraviolet radiation, flowers had to evolve ultraviolet markers so as to keep guiding the honeybees to them and keep the relationship going.

CLUE CELLS.

Explanation: Gardnerella vaginitis is also known as bacteria vaginosis.

It is a disease of the reproductive system that affects mostly women of child bearing age, bacteria vaginosis occurs when there is a shift or change in the normal balance of bacteria found in the Vagina,this change in bacteria balance results in infection.

Symptoms of includes vaginal itching, abnormal vaginal discharge and odour.

When Gardnerella vaginitis is diagnosed,the following are being noted;

Clue cells; this involve coating vaginal skin cells with bacteria,clue cells are visible on microscopic exam of vaginal fluid.

When vaginal fluid is tested and the PH shows low acidity( a PH greater than 4.5 precisely).

(WHIFF TEST)When there is a fishy odour upon combination of vaginal discharge with a drop of magnesium hydroxide. A glass slide is used for this test.

Answer:  4.4 pounds

Explanation:

Sprite is mostly water (like most other drinks), and so it weighs about as much as water does, and water weighs exactly 1 kilogram per liter. So 2 liters = 2 kilograms = 4.4 pounds.

Provided question is incomplete as proper information is not given, however, the complete question is as follows:

Several different kinds of bonds or interactions are involved in generating and maintaining the structure of proteins. List five such bonds or interactions.

Select the five correct answers.

Answer:

The correct answer is:

peptide bond

hydrogen bond

ionic bond

disulfide bond

hydrophobic bond

Explanation:

In protein structure their are different type of bonds present in between different atoms of amino acid to forming or maintaining the protein and its structure. These bonds are as follows:

Peptide bond: These bonds are present in all amino acids,  joins monomers in primary structure

Hydrogen (not between R groups): these are bonds present in all amino acids, these bonds are responsible for the secondary structure .

Hydrophobic:  leucine could be involved, These type of interactions are responsible for tertiary and Quaternary structure

Ionic: glutamate could be involved in such bond, these are also responsible for the tertiary and Quaternary structure

Disulfide: cysteine could be involved in such bonding, tertiary and Quaternary structure

Answer:

Explanation:

It's simply law of osmosis.

In osmosis solvent particles move from lower solute concentration to higher solute concentration until both the solution acquire the same concentration. So when a plant cell is kept in hypertonic solution (having more solute concentration), the solvent particles move outside the cell causing it to shrink, which is also known as plasmolysis of cell.

When a plant cell is kept in hypotonic solution (having less solute concentration), the solvent particles move inside the cell causing it to swell up which is also known as deplasmolysis. But due to the presence of cell wall, plant cell can not burst. Cell wall is a very stratchable boundary made up of cellulose mainly which makes the plant cell non-collapsable (but animal cells can burst in hypotonic solution due to absence of cell wall)

Water's properties high heat capacity caused by hydrogen bonding, after absorption of heat, hydrogen bonds are broken and water molecules can move freely.

Water is the chemical substance represents as H2O that is two hydrogen atoms covalently bonded to a single oxygen atom in one water molecule.

It is a colorless and tasteless have hydrogen bonds resulting present in the condensed form.

It has high melting and boiling points, with high specific heat, thermal conductivity, surface tension, dipole moment, etc.

It is an excellent solvent and helps in the transportation of ions and molecules, high latent heat of vaporization which maintain the body temperature.

Water is amphoteric in nature as it act as both acid and base, some electropositive elements reduce water to hydrogen molecule.
