what is the maximum initial reaction rate for the enzyme at ph7
At pH 7, this enzyme's maximal initial reaction rate is 350 X 10>6 per minute of product produced with a saturation of 2–4g of substrate.
An enzyme-catalyzed reaction has a very productive relationship between the substrate concentration and the starting reaction, but the pH of the supplied solution has a significant impact on this relationship. pH7 has the highest rate of productivity.The connection is roughly linear with respect to substrate concentration and pH level up to the saturation point, which in this case was attained between 2g and 4g of substrate.Up until the point of saturation, which in this instance is between 2g and 4g of substrate, the reaction is more productive with increasing concentration. Beyond that point, adding more substrate has no extra benefit.Learn more about the effect of pH on reaction rate here:

scientific hypothesis
By Kara Rogers • Edit History
scientific hypothesis, an idea that proposes a tentative explanation about a phenomenon or a narrow set of phenomena observed in the natural world. The two primary features of a scientific hypothesis are falsifiability and testability, which are reflected in an “If…then” statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation. The notion of the scientific hypothesis as both falsifiable and testable was advanced in the mid-20th century by Austrian-born British philosopher Karl Popper.

In humans, a brown eyed man whose father was brown eyed and whose mother was blue eyed, married a blue eyed woman whose father and mother were both brown eyed. The couple has a blue eyed son. For which individuals can you be sure of the genotypes? What genotypes are possible for the others? (SHOW WORKING AND PUNNET SQUARE)
Only the father of the brown-eyed man, who also had brown eyes, cannot be positively recognised by genotyping. We can infer that he carried at least one dominant B allele from the fact that he had brown eyes. He was either homozygous dominant BB or heterozygous Bb, although this cannot be determined. These genotypes (BB or Bb) might both exist based on the information provided.
Individual Genotypes: Based on the information given, a geneticist is confident about the genotypes of the following people: The father of the brown-eyed man: The mother of the blue-eyed man with brown eyes is: bb Bb Brown-eyed man (because his mother could have only contributed a b allele to him) bb Blue-eyed woman Father of the blue-eyed woman (had brown eyes): Bb (for woman to have blue eyes, father must have contributed b allele) The mother of the blue-eyed woman had brown eyes. Bb (for woman to have blue eyes, mother must have contributed b allele) Brown-eyed man and blue-eyed woman's blue-eyed son: bb (confirms that brown-eyed man carries b allele).

Explanation:
Hippos have a healthy and mostly herbivorous appetite. Adults eat about 80 lbs. (35 kg) of grass each night, traveling up to 6 miles (10 km) in a night to get their fill. They also eat fruit that they find during their nightly scavenging, according to National Geographic.
. How do the parent guinea pigs and their pups provide evidence that support Mendel's conclusion about inheritance?
The guinea pig is a small, domesticated rodent native to South America. Humans domesticated this species somewhere about 5,000 B.C., perhaps from the Montane Guinea Pig.
The domestic version, sometimes known as "Cavies," is a separate species today. They are frequently kept as pets in homes and are typically well-liked because to their docility and love to people. Continue reading to learn more about the Guinea Pig. These rodents are quite little, with tiny ears, short legs, and no tail. Cavies normally weigh one to two pounds and are eight to nine inches long.
Animals with a variety of colors and coats have been painstakingly produced by humans. Therefore, instead of being white, cream, grey, black, orange, or any combination of the aforementioned hues, these little rodents are brown.

Consider the scenario.
A scientist sets up an experiment to see how sugar in the diet of
rats affects their weight. The scientist feeds one group of rats a
diet high in sugar, another group a diet of moderate sugar levels,
and a third group a diet low in sugar.
All of the rats in the experiment are the same species and age
and start the experiment at a healthy weight. The rats also
receive the same kind of sugar.
What is the independent variable?
A. amount of sugar
B. weight of the rats
C. age of the rats
D. type of sugar
The dependent variable is affected by the independent one. The amount of sugar (heigh, moderate, low) is the independent variable. Rats weight is the dependent variable.
What are the dependent and independent variables?Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results.
This variable is not affected by any other one but influences or causes a reaction in other variables.
The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one.
Its response might be either directly proportional or inversely proportional to the change in the independent variable.
In the exposed example,
Aim of the experiment: to see how sugar in the diet of rats affects their weight.Independent variable: Amount of sugar (high, moderate, low)Dependent variable: Rats weightControl variables: Type of sugar, initial weightThe amount of sugar (independent variable) that was provided to rats will affect or influence their weight (dependent variable).
So, rats weight will change according to the sugar they get in the diet.

D. All living things are composed of cells.
all chemical processes which take place in living cells ??
Biochemical reactions are chemical processes that occur within living organisms.
Chemical processes known as "biochemical reactions" happen within the cells of living beings. The study of biochemistry shows that understanding both chemistry and biology is necessary to comprehend how cells function in living things at the level of the organism. Metabolism is the collective term for all biological processes that occur within an organism. Both exothermic and endothermic reactions are a part of it.
Catabolic reactions are exothermic processes that occur within living things. These processes disassemble molecules into smaller parts while also releasing energy. The breakdown of glucose is an illustration of a catabolic reaction, which releases the energy required by cells for their vital functions. Anabolic reactions are endothermic processes that occur within living things. These processes combine tiny molecules into larger ones.
A biochemical reaction is the transformation of 1 molecule to a one-of-a-kind molecule inside a mobile. Biochemical reactions are mediated through enzymes, which might be biological catalysts which could alter the rate and specificity of chemical reactions internal cells.
Photosynthesis, gluconeogenesis (synthesis of glucose from non-carbohydrate resources, specifically used by the brain), protein biosynthesis, fatty acid synthesis, glycolysis, Krebs cycle, urea cycle, glycogenolysis are some common examples of biochemical reactions.

the arrows in the diagram stands for forces in earth,s crust pulling apart the two slabs of rock. this force is called
a.) tension
b.) elavation
c.) compression
d.) shearing
Answer:
I'm pretty sure it is c or a
Forces in earths crust pulling apart the two slabs of rock, this force is called Tension. Therefore, option (A) is correct.
Earth's crust tension pulls rock apart. At divergent plate borders, tectonic plates move apart. Faults form when tensional forces strain and thin rocks when plates separate. These faults can create rift valleys, mid-ocean ridges, and other geologic features.
Seafloor spreading and continental rifting are driven by tension. As plates separate, magma from the mantle rises to build new crust. New crust is formed at mid-ocean ridges. Tensional forces can also cause continental rifting and ocean development. Tension forms Earth's crust and moves tectonic plates. Therefore, option (A) is correct

Although the total distance the impulse travels in the reflex arc is less than 3 meters. the time taken is more than 0.04 seconds and the time taken is more than expected because of Synapses or due to gaps between neurons.
Diagram displays the whole reflex arcs from the tip of the finger to the spinal cord and then back out to a closer muscle, possibly in the forearm or the arm. Because the signal doesn't have to go all the way back to the finger, the total distance is less than 3 meters. Considering that it just travels back a portion of the way, less than 3 meters, it takes. Let's see, it takes more than twice as long, therefore the query makes us think about why the delay. Where is the hold-up what is happening there, and the key to this is that the gray matter of the spinal cord doesn't truly contain mylin, despite the fact that we said it- accelerates electrical conduction through the axon in the nerves of the extremities. Mylin has a whitish color, which contributes to the white matter's appearance of whitishness. Thus, the electrical signal becomes slower.

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.
Explanation:
If the temperature increases then that will decrease the sugar but not the ATP and NADPH. So I predict that diuron will inhibit the photosynthesis because if photosystem II is infered with it then photosynthesis wouldn't work.And also, because paraquat will lower the NADPH and sugar but not ATP. Hence Diuron is the only choice left.
