In a plant, a single locus affects both berry color and berry size. There are two mutant alleles (R1 and R2) in addition to the wild-type allele (R0). Individuals that are R0R0 have large, white berries. Individuals that are R1R1 or R0R1 have red berries, individuals that are R2R2 or R0R2 have small berries, and R1R2 individuals have berries that are both red and small. Thus...R1 is dominant to R2.R2 is dominant to R1.R1 and R2 exhibit incomplete dominance.R1 and R2 exhibit codominance.R1 and R2 exhibit pleiotropy.
During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes. In order for this to occur, which of the following statements must be true?A.) The energy in the new compounds that are formed must be equal to the energy in the bonds of the food molecules. B.) New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken. C.) New compounds with higher-energy bonds must be formed when the low-energy bonds in food molecules are broken. D.) The new compounds that are formed must be more complex than the food molecules that were broken down.

Answer:
Translation can be described as a process in which proteins are synthesized.
Differences between the prokaryotic and eukaryotic translation are:
- In prokaryotes, transcription and translation occur simultaneously. In eukaryotes, transcription and translation are two different process. Transcription occurs in nucleus whereas translation in cytoplasm.
- In prokaryotes, the 5' end of mRNA is available for translation whereas the mRNA of eukaryotes has to under go changes before translation begins.
- The ribosome type for prokaryotic translation is 70S and for for eukaryotes is 80 S.

Answer: The environmentalists are concerned about the introduction of genetically engineered trees because their introduction into the environment could have unexpected interactions with the other plants and animals present in the ecosystem.
Other reason can be loss of native species. The native species that is originally present in the environment can be lost due to the introduction of genetically engineered plant species.

The kingdom that includes the organism that causes Lyme disease would be monera.
What causes Lyme disease?
Lyme disease is caused by bacteria in the Borrelia genus. The genus includes both burgdorferi and mayonii species.
Bacteria generally belong to the kingdom of organisms known as Monera. The kingdom is made up of unicellular organisms that are prokaryotic in nature. The cells of organisms in this kingdom lack nucleus as well as membrane-bound organelles.

Answer: Through their Respitory and Digestive Systems.
Explanation: Organisms breathe in order to get necessary oxygen into the body as well as consume foods and liquids in order to get all the other nutrients required to make energy. Energy is created with these nutrients through individual cells in a form called ATP.

Que.1
Standard IV solution used as a blood volume expander (0.9% NaCl is commonly used)
HYPERTONIC ISOTONIC.
Answer- isotonic.
The standard 0.9 % Nacl solution is isotonic. A solution is isotonic if it is of equal solute concentrations with the surrounding environment. Therefore, 0.9 % Nacl solution will not gain or lose fluid via osmosis across its wall. Rather its intravenous introduction will be at the same concentration with the intracelluar fluid leading to expansion in volume.

Type of edema in the lower extremities
DEPENDENT INDEPENDENT.
Answer-Dependent
Accumulation of blood in body tissues (Oedema) usually occurs due to effect of gravity on the body. Gravitational force pulls body fluid towards the extremities and lower part of the body.Therefore fluids accumulates under the skin, trapped in the veins of leg (especially from prolong standing), feet and hands. It may also be as a result of complication from medication, or pregnancy term is called Dependent Oedema. Because it is gravity-related Oedema.

Increases sodium and water retention by the kidneys
RENIN ALDOSTERONE
Answer-Aldosterone
In condition of lower blood volume, lower salt level or increse blood pressure,one of the compensatory mechanism is the release of hormone Aldosterone from the pituitary gland, under the influence adreno cortico tropic hormone The Aldosterone stimulate the walls of the distal convoluted tubule and collecting duct to increase re-absorption of sodium ions, from the urine, sweat and gut back into the blood. Water follow by osmosis. This raises the water level of the blood with corresponding increase blood volume, reduction in salt balance and drop in blood pressure.

The main intracellular cation
POTASSIUM MAGNESIUM
Answer:Potassium
This is the main intracellular cations of the cell. It concentration is maintained by the activities of sodium-potassium pump along cell membrane. These pump made of channel of protein regulate the movement of potassium ions in and out of the cells. Its positive charge(together with that some anions) is responsible for the positive charges in the intracellular layer.

Fluid sequestration in the body cavities
PITTING EDEMA /'THIRD SPACE ACCUMULATION.
Answer; third space.
The space between adjacent cells may be filled with fluids, that escape from the blood vessels into the interstitial space when there is too much water in the blood,.This fluid space is called the third Space. It has no appreciable function.
Que-
Excreted in response to fluid volume overload.
ALDOSTERONE NATRIURETIC PEPTIDES.
Answer. Natriuretic peptides
An increase in blood fluid volume usually correspond with the release of Natriuretic peptides under the in influence of the pituitary gland and the heart in the body. These promotes the loss of sodium ions by the kidney, with corresponding loss of water by osmosis.Therefore large volume of hypotonic urine containing excreted sodium is produced. This lowers the blood fluid volume,
Que;
Diminished water volume in intracellular fluid and extracellular fluid
DEHYDRATION THIRD SPACE ACCUMULATION.
Answer; Dehydration
Dehydration is depletion of water level of the plasma fluid, due to loss of fluid from the intracellular and extracelular fluids cell layers into the surrounding hypertonic medium.The cells shrinks, with loss of the organelles. Hypotension, confusion also set in.
Que;
Characterized by excess fluid in interstitial and intracellular fluid compartments
DEHYDRATION EDEMA,
Answer.Oedema
The accumulation of fluid in the space between cells(interstitial space) is called oedema.it may be caused by damage to the kidney, liver, to the veins of the legs etc,This damages lead to poor drainage of the blood by the veins leading to fluid retention.
Que
Occurs when application of pressure over a bony area leaves an indentation
PITTING EDEMA DEPENDENT EDEMA
Answer. Pitting Edema.
Mathematically, Pressure is equal to force over the area where the pressure was applied.(P=F/A). During accumulation of fluids under the skin due to oedema; if a pressure is applied on the fluid accumulated area, an indention due to the force which was applied will be left momentarily, and gradually disappear. this is called Pitting Oedema.
