Protists vary in structure and function more than any other group of organisms. However, here are some common traits: a.All have membrane-bounded organelles, and so are ___________________. b.Most are single-celled, or ___________________________. c.They get their food in several ways. Some contain chloroplasts and do photosynthesis, and so are considered __________________. Others ingest food particles and so are ____________________.
Answer:
a. eukaryotes
b. unicellular
c. autotrophs; heterotrophs
Explanation:
Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.

What is a ribososme?Ribosomes, also called Palad granules (after their discoverer George Palade, for their granular structure), are macromolecular machinery found in all cells that perform biological protein synthesis (mRNA translation).Ribosomes join amino acids in an order determined by the codons of the messenger RNA (mRNA) molecule to form a polypeptide chain. Ribosomes are composed of two major components, the large and small ribosomal subunits.Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins).Ribosomes and related molecules are also known as the translational apparatus.The ribosome is a ribonucleoprotein complex because it is composed of a complex of RNA and protein.Each ribosome is composed of smaller (30S) and larger (50S) building blocks called subunits.

When you use the same histone protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (5 points) a. The histone protein has fewer basic amino acids than albumin. b. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Answer:
A. The histone protein has fewer basic amino acids than albumin
Note: The question is incomplete. The complete question is given below:
You use the Bradford (coomassie) assay to determine the concentration of a whey protein. You use bovine albumin as your standard. You determine the histone protein concentration to be 3 mg/ml. When you use the same whey protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (2 points) The histone protein has fewer basic amino acids than albumin. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Explanation:
The Bradford assay measures the concentration of proteins in a a protein sample using a color change that occurs from brown to blue when the protein in the sample binds to Coomassie dye. The Coomassie dye specifically binds to basic and aromatic amino acids in the protein. A standard curve is created using absorbance data from samples of proteins of known concentrations. The spectrophotometer is set to read at 595 nm in the Bradford assay as the peak absorbance of Coomassie Blue once bound to proteins occurs at 595 nm.
The higher the concentration of proteins, the higher the color intensity and the higher the absorbance values.
Since when bovine serum albumin was used as standard, the sample protein concentration was lesser than when the protein sample was used as standard, this means that the sample protein binds less to Coomassie dye as a standard thereby giving a higher sample protein concentration than the BSA standard. Therefore, the histone protein has fewer basic amino acids than albumin.

Carbohydrates like glucose can undergo spontaneous rearrangement to give an alternate configuration for the anomeric carbon when the ring is free in solution. However, when glucose is covalently attached to another sugar through C1, this rearrangement cannot occur. Consequently, the configuration of carbohydrate oligomers and polymers is fixed. Why can't glucose rearrange when in a polymer form?
Answer:
The presentation according to another circumstance is categorized in the following section.
Explanation:
Glucose constructs anomers because of the extreme involvement of flexible metal-carbon because that continues to exist as something of a monomer. However, when plastics are established, transformation is limited with glycoside formation of complexes among both anomeric carbon atoms.
Sucrose, besides obvious reasons, would be manufactured by glucose and fructose, which have been connected by something like a glycerol backbone involving glucose carbon atom as well as fructose. The mechanism including its creation of anomers even by movement through carbon becomes called "Mutarotation" Sucrose doesn't always show mutation.In humans, mitosis produces cells with ____ chromosomes and _____ chromosomes are found in the gametes after Meiosis.

There is a multitude of evidence that supports how life has changed over time due to variation in the gene pool of different species. Which of the following choices below represents a scientific theory that explains these changes? *
A. As environments and ecosystems change over time, those that acquire suitable traits are more likely to survive and reproduce and the gene pool changes because organisms must adapt to survive and reproduce.
B. As environments and ecosystems change over time, those with variations for traits that are more successful in the new conditions are more likely to survive and reproduce, thus changing the allele frequency in the gene pool.
C. Because the environments and ecosystems show little change over time, organisms are already adapted for surviving in their given habitats for which they are made.
D. Because the environments and ecosystem show little change of time, the organisms that choose to adapt to different environments will migrate and become suited for new habitats.
Answer: A. Environmental drivers plus genetic variation in the population result in natural selection
Explanation: over geological time environmental conditions change. Organisms do not survive in one environmental niche with traits adapted to a possible future change that might suit those traits. Adaptation is not a matter of choice: adapt if possible or go extinct.
There is a (badly named) concept called pre-adaptation, which is that variations in some existing trait render adaptation to a different environment more likely.

In muscle tissue, what is the reactant of lactic acid fermentation and the product that builds up during intense exercise?
The reactant of lactic acid fermentation and the product that builds up during intense exercise is glucose.
Homolactic Fermentation in Muscle CellsLactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. Glucose is the simple sugar reactant used in this type of homolactic fermentation, instead of lactose used in the case of bacteria. This process of energy production is employed by muscle cells when oxygen levels are low, such as during periods of extreme exercise.Learn more:

3. What things does your body do automatically to cool down or warm up?
Answer:
For your body to cool down one method is to sweat.
Explanation: Your sweat glands release sweat, which cools your skin as it evaporates. This helps lower your internal temperature
To keep warm your body shivers and your blood pressure decrease, it brings the blood back to the heart to keep you warm, also in you blood, your hormones create glucungons that makes the liver shoot out glucose to keep you warm. To keep cool you body sweats and in you blood the hormones create something called insulin that makes you cell take in the glucose in you blood.(Fun Fact: the things that I just said are negative feedback).
