Answer:
50 micro mol/min
Explanation:
So, we have the following parameters which are going to help us in solving this particular Question or problem;
=> For the wild type enzyme, the value for the Maximum velocity = 100 micromol/min.
=> For the mutant type enzyme, the value for the Maximum velocity = 1 micromol/min.
So, we can determine or calculate the value for the initial velocity for each of the enzyme type by using the formula below;
Initial velocity = (substrate concentration × maximum velocity) / substrate concentration + Km.
Therefore, for the wild type enzyme; the Initial velocity = (substrate concentration × maximum velocity) / substrate concentration + Km.
Initial velocity =( 10mM × 100micromol/min) ÷ ( 10mM + 10 mM ) = 50 micro mol/min.
Initial velocity for the wild type enzyme = 50 micro mol/min.

How do genetic factors, environmental factors, and pathogenic agents affect both individual and public health?
Answer:
Genetic factors are very important because genes make our strong immune system that is not badly affected by weak traits or disease. Environmental factors are important because they can cause/spread disease.
How can this PLR (pupillary light reflex) help you determine whether the lesion is in the eye itself or elsewhere?
Answer:
Pupillary light reflex refers to the contraction that the pupils present when they light up. In cases of injury to the optic nerve, when the eye where the injured optic nerve is illuminated, since it cannot conduct the stimulus to the brain, neither pupil closes.
Explanation:
Pupillary light reflex refers to the reaction that causes the pupil to close with light thanks to the contraction of the sphincter of the pupil and to open in the dark thanks to the relaxation of that muscle by not receiving any stimulus. A light stimulus reaches the eye and in the retina it is transformed, through a chemical reaction, into an electrical stimulus that will be transmitted through the optic nerve and the visual pathways to the brain. The visual cells of the retina, rods and cones, also act as light receptors that control the pupil's motor activity. Thus, pupil-motor thresholds to light follow the same spectral sensitivity deviations as visual thresholds, which are a function of the state of light adaptation of the retina.
A student’s cat gave birth to a litter of kittens. She noticed that one of the kittens had brown fur and one of the kittens had white fur. Which of the following best explains how two kittens in the same litter can have different fur colors?
Explanation:
because the mom must be either brown your white and the dad must be the other color
The best explanation for the statement that how two kittens in the same litter can have different fur colors are the brown kitten and the white kitten have different combinations of the genes for fur color. The correct option is B.
What is genetics?The study of genetics covers how a person inherits traits from their parents. It explains how familial traits—be they simple like eye color or complicated like disease susceptibility—run in families.
Both genomics and genetics have an impact on health and disease. The study of genes and how particular traits or conditions are passed down from one generation to another is referred to as genetics. The study of a person's entire gene pool is referred to as genomics.
Therefore, the correct option is B. The brown kitten and the white kitten have different combinations of the genes for fur color.

If a net force of 24 Newton’s is applied on an object of mass 6 kilograms, what will be the acceleration of the object
Answer: 4 m/s
Explanation:
i got it right
The acceleration of the object is 4 m/s²
From Newton's second law of motion which states that, " the force acting on an object is equal to the to mass of of that object times its acceleration"
That is,
F = ma
Where
F is the force
m is the mass
and a is the acceleration
From the formula
F = ma
We can write that
[tex]a = \frac{F}{m}[/tex]
From the given information
F = 24 N
m = 6 kg
Putting the parameters into the formula,
[tex]a = \frac{F}{m}[/tex]
We get
[tex]a = \frac{24}{6}[/tex]
∴ a = 4 m/s²
Hence, the acceleration of the object is 4 m/s²

In humans, to fold the tongue is a dominant trait (L), and the straight tongue is the recessive trait. What are the probabilities that the offspring can fold the tongue?
The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case:
1. dominant parent and recessive parent
2. heterozygous parents
Answer:
1. dominant parent and recessive parent:
dominant parents can be represented by LL and recessive parent is represented by ll, so the gametes would be L, L and l, l.
so,
L L
l Ll Ll
l Ll Ll
so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue.
2. heterozygous parents
In this case, parents have Ll genotype and gametes would be L and l for each parent so,
L l
L LL Ll
l Ll ll
In this case, one is pure dominant and two heterozygous whereas only one is recessive so, the phenotype of offspring that cant fol the tongue would be:
3/4 = 75%

3. (-2, 0) and (0,5)
2. (1, -2), (3, 3)
4. a = 2, b = -7
5.m=2,(3,-1)
Answer:
(1) m = -5, b= 1
[tex]\frac{x}{a} + \frac{y}{b} = 1[/tex]
put b=1 (given)
[tex]\frac{x}{a} + \frac{y}{1} = 1[/tex] => y = -x/a + 1
-1/a is representing slope here which is given as -5
-1/a = -5 => a = 1/5

Answer:
Fossil fuels are used to generate energy and are responsible for global warming.
Explanation:
Fossil fuel is a residue that is formed by reaming the plants and animals that have been buried inside the earth for thousands of years. Fossil fuels are a conventional form of energy and cannot be renewed. These energy sources are used by man for burning, lightning, etc. Fossil fuels are a cheap source of power and energy supply there are many types as coal, oil or petroleum, uranium, and natural gas.

what basic chemical do we break apart during cellular respiration
fats
glucose
water
or
amino acids
Answer:
glucose
Explanation:
During cellular respiration, living cells break apart the glucose molecules.
In this process, energy is being released.
It's the process of burning because the breaking apart of glucose releases the energy slowly and uses it for biochemical processes. Glucose and oxygen react and form carbon dioxide and water, and in this way, they release energy.
When calculating heritability in finch beak size using parent/offspring data, we find that 70 percent of the variation in the trait is due to genetics. What might explain the remainder of the variation? Select all that apply.
A.
nutrition
B.
color
C.
precipitation
D.
stress
E.
rarity
F.
temperature
Answer:
A. nutrition
Explanation:
The most likely explanation for the remainder of the variation would be nutrition. Little is known about how exactly nutrition affects genetics and heritability, but it is known that it does. Scientists believe that traits that allow a species to feed more successfully have a drastically increased chance of appearing in offspring as it greatly contributes to their survival. When a trait does not allow the species to gain the proper nutrition, the species tends to develop other traits to accomplish this which then get passed on to offspring.
Answer:
A. Nutrition
C. Precipitation
F. Temperature
