Answer:
pH of 6.5
Explanation:
The pH favorable to an enzyme where it is most active is called optimum pH. The optimum pH of sucrase is about 6.0 while that of catalase is 7.0. Both enzymes can however still show some activity when the solution is slightly basic or slightly acidic (from it's optimum pH). Hence, getting the middle point (6+7/2 = 6.5) between the optimum pH of the two enzymes and preparing same will ensure the enzymes show some activity.

Amino acids and sugars are both required by animals to maintain their health. Without a diet containing both of these, animals cannot
survive. Amino acids are obtained by animals when they digest .
A) nucleic acids
B) carbohydrates
C) proteins
D) lipids
Answer:
c
Explanation:
Amino acids are the monomers of protein molecule.Each amino acid molecule is made up of an amine group,caboxylic acid group,Hydrogen atom and R-group. All are attached to the alpha carbon.It is the R-side group that differentiate one amino group from another.
These amino acids units are joined together by the peptide bonds to form the giant protein molecules
The arrangement, the number of the amino acids and the orientation of these amino acids can be used to classify protein into different primary,secondary, tertiary and Quaternary levels.
Generally protein digestion begins and ends in the stomach and the small intestine. by enzymes pepesin and renin, and the activities of enzymes of the pancreas chymotrypsin and trypsin,respectively.
The cells in the wall of the small intestine finally breakdown the digesting protein into amino acids by the activities of the enzymes there.

Cats have many different cells in their bodies * Cells come from existing cells The cell is the basic unit of life All living things are made up of cells Cells take in and use energy
Answer:
By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues and proposed the unified cell theory. The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

In prokaryotic cells, regulator proteins bind to a section of DNA called a/an
A)chromatin
B)repressor***
C)promoter
D)operon
“*** is my answer”
Answer:
C) Promoter
Explanation:
Gene expression is the process of synthesizing RNA from a gene (transcription), and subsequently, proteins from mRNA (translation). In both prokaryotic and eukaryotic cells, gene expression is controlled at the transcriptional level, which is regulated by certain proteins called transcription factors. Transcription factors are proteins that regulate the synthesis of a protein from a gene.
Transcription factors regulate the progression of transcriptional process by binding to a regulatory region on the DNA sequence about to be transcribed called PROMOTER. The promoter region is a DNA sequence contained in the OPERON. This binding influences the binding of the transcription enzyme, RNA polymerase in order for transcription to start.

Show the energy of Oxidation of two mole pyruvic acid.
Answer:
Methanesulfinic acid (MSIA) is an important intermediate in the oxidation of dimethyl sulfide (DMS) in the marine boundary layer. The oxidation of MSIA by ozone in the gas phase to form methanesulfonic acid (MSA) was investigated using theoretical calculations in this paper. Three pathways can be found for the reaction of MSIA with ozone. The highest energy barrier is 13.02 kcal mol−1 in the most favorable pathway. By comparing the reaction rate of MSIA + O3 with that of MSIA + OH, it can be concluded that the oxidation of MSIA by O3 to form MSA is of minor significance relative to its oxidation by OH radical in the gas phase. This study can provide some information for the theoretical and experimental studies in the significantly heterogeneous and aqueous-phase oxidation of MSIA by O3.

Describe the three stages of urine production. Be sure to include how each stage relates to the structure of the nephron and why the composition of urine reveals information regarding the health of the body.
Answer:
Urine is considered to be a true reflection of bodily health because it releases metabolites not necessary for our body.
In some situations, other solutes or secretions are eliminated since they are increasing or are a sign of pathologies.
Clear examples of these situations are: increased protein in urine, presence of hematocrit in urine, presence of glucose in urine, etc.
The three phases of urine formation are: glomerular filtration, reabsorption, and secretion.
Explanation:
The glomerulus and the nephron are responsible for the formation of urine.
Faced with certain pathologies such as diabetes, leukemias, urogenital infections, ketoacidosis, hypercapnia, increased ketone bodies, hyperproteinemias, etc., it is urine that reflects this state of imbalance in the body.
The glomerulus is a filter that is in charge of filtering in a meticulous way those residues of our organism, it releases the unnecessary residues and the chemical compounds or molecules or even cells in excess.
Glomerular filtration is higher or lower in terms of the volume of the afferent and efferent arteries of the renal glomerulus, and the pressures these vessels have within them.
This is how it correlates with the renin-angiotensin-aldosterone system, blood pressure, lungs, nutritional levels, and the overall health of the body.

A species of lizards migrates to a group of islands in the ocean. Over time, they diversified and evolved into several different species. Each species has a unique jaw shape that allows it to eat its own specific diet. This is an example of
gradualism because one species evolved into several different species over a relatively short amount of time
adaptive radiation because one species evolved into several different forms that occupy different niches
coevolution because the evolving lizard species changed in order to interact with the changing environment
convergent evolution because one species evolved into multiple species that live alongside each other
Answer:
adaptive radiation because one species evolved into several different forms that occupy different niches
No, because its genes are still the same. To evolve would mean that the frog had one set of genes as a tadpole, then a different set as an adult. It just doesn't work that way. The genes are the same.

Why would cells need to move things in and out?
Answer:
Cells do not generally allow such materials to go in because they are having a cell membrane outside. The cell membrane only allows the materials which are required for the growth of the cell such as water and minerals.
The independent variable is the variable that is changed in an experiment. a True b False
True.
Explanation:
An independent variable is what is changed by the scientist experimenting, or you. An easy way to remember this is that independent starts with an "I", which "I" am the one that manipulates the variable. A good experiment only has one independent variable.
A dependent variable is the data of the experiment. This could be the impact a drug has on individuals, how much a plant has grown, test scores of students, etc. What is measured at the end of an experiment is the dependent variable.
A control variable is something that is stayed constant throughout the experiment. This could be the amount of water, type of soil, amount of light, the color of light, etc. These things are not changed.

My leg is on fire: a case study on spinal and peripheral nerve anatomy answer
Hello. The question above is incomplete. The full question is:
My leg is on fire: a case study on spinal and peripheral nerve anatomy
Sarah Mitchell is a 68-year-old female who is normally healthy. However, about five days ago she began to feel very fatigued and started to experience a burning and tingling sensation on her right thigh.
You ask to see the area and upon visual inspection you notice 3–4 small, red, swollen areas with vesicles on the posterior aspect of her right thigh. She describes the pain to you, saying "it feels like the back of my leg is on fire and it hurts so bad." She denies being exposed to any excessive heat sources, any changes in her diet, and any changes in the type of body soap, lotion, or laundry detergent she is using. All other physical findings are within normal limits, but her oral temperature is 100.6°F. She complains about being under a lot of stress for the past three months because she has been helping take care of her husband, who is in the end stages of Alzheimer's disease. She has no known drug allergies, is a non-smoker, and attends a water aerobics class twice a week. You suspect she may be suffering from a particular viral infection, so you ask if she had chicken pox as a child. Sarah confirms that she had chicken pox and measles during childhood. Her answer confirms your suspicions that she is likely suffering from shingles (herpes zoster) due to varicella-zoster virus infection.

Answer:
Paresthesia: Term describing the loss of sensation in some region of the body, usually on the tongue, lips and buccal buccal. This loss of sensation occurs with the application of anesthesia in the desired location. Skin vesicle: Term that refers to the appearance of bubbles in the skin. These bubbles may have different sizes, but they all have a liquid inside them. The skin blister can cause itching, tingling and even a burning sensation. Dorsal: Term that refers to the region of the back in the body. It covers the back muscles and is present in the internal and external skeletons. Ventral: Refers to the front of a body and is related to the entire belly. Dormant: Refers to the lack of sensitivity in a muscle. This term is associated with the sense of something that is asleep and unavailable at the moment.A blue whale is louder than any animal around.
Go in search of a thing that also makes a loud sound.
The correct answer to this open question is the following.
A blue whale is louder than any animal around.
Go in search of a thing that also makes a loud sound.
Well, talking abound animals sounds, what about the roaring of a lion or a tiger. That is loud too, and scary.
If we do not want to refer to an animal sound, we could talk about the sound of the turbines of an airplane. That is loud. Indeed, floor airport operators have to use earplugs or other kinds of protection to avoid ear damage in the workplace.
The sounds of machines in many industries and factories are also very loud.
Glycogen, cellulose, and starch are all __________________. A. proteins B. polysaccharides C. nucleic acids D. lipids E. phospholipids
Select all that apply.
Answer:
It's B I think
Explanation:
Glycogen, cellulose and starch are all polysaccharides made up of monosaccharides bonded by a glycosidic linkage. Therefore, option (B) is correct.
What are polysaccharides?The most prevalent kind of carbohydrates in food are polysaccharides, often known as polycarbohydrates. They are long-chain polymeric carbohydrates made up of glycosidic connections that connect monosaccharide units. Using amylase enzymes as a catalyst, this carbohydrate may combine with water to create its component sugars.
The polysaccharides starch, cellulose, and glycogen are a few examples of. Polysaccharides are used as stabilisers and dietary fibre in the food industry. Polysaccharides may also be produced by bacteria, for instance while making yoghurt.

What does Rob mean when he says some tropical lakes do not "cycle
Answer:
He means that the surface doesn't mix with the deeper colder water and the water remains anoxic.
Explanation:
The statement that says that tropical lakes don't mix means that the surface layer of water does not mix with the deeper colder layer. This means that it remains anoxic.
What are tropical lakes?Tropical lakes have the following major classes. These are
shallow, lowland lakes; deep, tertiary lakes; high altitudinal lakes; rainforests lakes; man-made lakesThese are present at all latitudes and altitudes. Basic ecological processes like grazing, competition, predation and abiotic adaptation are simple in temperate and tropical lakes.
The tropical lakes of small size and intermediate age are not biotically more complicated than temperate lakes of similar size.
Fish have a key role to play in the tropic regions because many species because they consume zooplankton and also compete with them for food. This is an important co-evolution process between the fish and the algae which leaves a part of the algal community with a refuge for predation, and the zooplankton will have a decreased ability to exploit algae.
Therefore, the statement that says that tropical lakes don't mix means that the surface layer of water does not mix with the deeper colder layer. This means that it remains anoxic.
