Answer:
The correct option is C
Explanation:
Anaerobic bacteria used in sewage treatment helps to reduce the volume/amount of sludge in the sewage thereby producing methane gas from it. Some companies produce there own (not for sale) methane gas (as an alternate source of energy) through this process. Thus, a decrease in the amount of this bacteria (perhaps through death as described in the question) will lead to a decreased production of methane gas.

The retinohypothalamic path consists of a special population of retinal ganglion cells that have their own photopigment, called:
Answer:
melanopsin
Explanation:
this note might help you :
The retinohypothalamic tract (RHT) is a photic neural input pathway involved in the circadian rhythms of mammals. The origin of the retinohypothalamic tract is the intrinsically photosensitive retinal ganglion cells (ipRGC), which contain the photopigment melanopsin. The axons of the ipRGCs belonging to the retinohypothalamic tract project directly, monosynaptically, to the suprachiasmatic nuclei (SCN) via the optic nerve and the optic chiasm. The suprachiasmatic nuclei receive and interpret information on environmental light, dark and day length, important in the entrainment of the "body clock". They can coordinate peripheral "clocks" and direct the pineal gland to secrete the hormone melatonin.
information about melanopsin : Melanopsin is a type of photopigment belonging to a larger family of light-sensitive retinal proteins called opsins and encoded by the gene Opn4.[5] In the mammalian retina, there are two additional categories of opsins, both involved in the formation of visual images: rhodopsin and photopsin (types I, II, and III) in the rod and cone photoreceptor cells, respectively.
Aerobic respiration has 3 stages: glycolysis, Kreb's cycle, electron transport
chain. What happens in each stage? How many ATP molecules made during
each stage?
What happens in each stage?
GLYCOLYSIS: "In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and NAD+ is converted to NADH." (Khan Academy)
KREB'S CYCLE: "This is a central driver of cellular respiration. It takes acetyl CoA—produced by the oxidation of pyruvate and originally derived from glucose—as its starting material and, in a series of redox reactions, harvests much of its bond energy in the form of NADH, FADH2, and ATP molecules. The reduced electron carriers—NADH and FADH2—generated in the TCA cycle will pass their electrons into the electron transport chain and, through oxidative phosphorylation, will generate most of the ATP produced in cellular respiration." (Khan Academy)
ELECTRON TRANSPORT: "In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient." (Khan Academy)
How many ATP molecules made during each stage?
GLYCOLYSIS: 2 ATP
KREB'S CYCLE: 2 ATP
ELECTRON TRANSPORT: 34 ATP

Suppose that Rosie and Ross are both carriers for PKU (a rare autosomal recessive disease.) If they have eight children, what is the probability that all of eight children will have the same phenotype?
Answer:
1/65,536 = 0.001523 %
Explanation:
A: normal allele
a: recessive allele causing PKU
The probability that Rosie and Ross have one child with PKU will be >>
Aa x Aa = 1/4 AA; 1/2 Aa; 1/4 aa
In consequence, the probability that Rosie and Ross have eight children with PKU will be >>
(1/4)⁸ = 1/65,536 = 0.001523 %
If Rosie and Ross are carriers of PKU, if they intend having 8 children, the probability that they will all have the same phenotype is: [tex]\mathbf{\frac{1}{65,536}; 0.001523 \%}[/tex]
Given that Rosie and Ross are both carriers of the recessive disease, it means that for the disease to manifest itself, two recessive alleles must be present in an allelic pair.
Using P and p to denote the dominant and recessive alleles respectively, we have the following gene of both parents:
Rosie - PpRoss - PpThe cross between both parents has been provided using a Punnett square as shown in the attachment.
The cross shows that, for any cross between both parents, there is [tex]\frac{1}{4}[/tex] probability that the child would have the phenotype, pp, which means the child would have the are autosomal recessive disease.
Therefore, the probability for for 8 children having the same phenotype will be:
[tex]\frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} = \frac{1}{65,536}[/tex]
This is also approximately: [tex]\frac{1}{65,536} \times 100 = 0.001523 \%[/tex]
Therefore, if Rosie and Ross are carriers of PKU, if they intend having 8 children, the probability that they will all have the same phenotype is: [tex]\mathbf{\frac{1}{65,536}; 0.001523 \%}[/tex]

Identify the organelles in the cell. Label A Label B Label C Label D
Answer:
This question is incomplete
Explanation:
This question is incomplete but the completed/similar question with the diagram is in the attachment below.
First of all, the cell is a plant cell because of the presence of the large central vacuole present and also the green colour of the outer part of the cell (which is not a coincidence). Let's proceed to identifying the organelles.
Label A is the large central vacuole. This is not the nucleus as might be confused with because the nucleus is the next big reddish organelle to the right of the vacuole.
Label B is the cell wall. Because this is a plant cell, it has a cell wall which can be clearly seen to be the most outermost layer. While the next yellow boundary line is the plasma membrane.
Label C is the chloroplast. Recall from elementary biology that the chloroplast stores the green pigment chlorophyll. The green colour of this internal organelle makes it identifiable as the chloroplast.
Label D is the starch granule. The shiny semicrystalline structure of this organelle makes it identifiable as the starch granule.
Answer:
Chloroplast, Vacuole, Cell wall, Endoplasmic reticulum
Explanation:
Label A: Chloroplast
Label B: Vacuole
Label C: Cell wall
Label D: Endoplasmic reticulum

What happens to the force between the spheres when you increase the mass of one of the spheres?
What happens to the force between the spheres when you increase the mass of both spheres?
When you have different masses for each sphere, how does the force that the larger mass sphere exerts on the smaller mass sphere compare to the force that the smaller mass sphere exerts on the larger mass sphere.

The force of attraction between 2 objects is called gravity. Why do you think that an object, like your notebook, pulled towards you? Explain your reasoning.
Answer:
So i just finished doing this project and this what i put, I hope this helps (:
Explanation:
1. When mass 1 increases the force between the objects increases. If Mass 2 decreases, the force between the objects decreases
2. An object with more mass has more/less gravitational force than an object with a smaller mass. Objects that are closer together have more/less of a gravitational force between them than objects that are further apart. The more separation two objects have, the more the force between them decreases.
3. The forces are equal (Newton's third law of motion)
4. The force between the spheres will quadruple
5. ( I dont know what this is )
6. The force of gravity exerted by the notebook on you is negligible
--The force of gravity
If there is a force between all masses, why are you not pulled toward your desk by the desk’s gravity when you walk away from it? Remember that the net force on you determines how your motion changes. The force of gravity between you and the desk is extremely small compared with other forces constantly acting on you, such as friction, the force from your muscles, Earth’s gravity, and the gravitational pull from many other objects. The strength of the gravitational force between two objects depends on two factors, mass and distance. The Mass of the Objects The more mass two objects have, the greater the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled.
--The Distance Between the Objects
As distance between the objects increases, the force of gravity decreases. If the distance is doubled, the force of gravity is one-fourth as strong as before.
--Gravity on Earth
The force of gravity acts on both masses equally, even though the effects on both masses may be very different. Earth’s gravity exerts a downward pull on a dropped coin. Remember that every action force has an equal and opposite reaction force. The coin exerts an equal upward force on Earth. Because the coin has an extremely small mass compared with Earth, the coin can be easily accelerated. Earth’s acceleration due to the force of the coin is far too small to notice because of Earth’s large mass. The acceleration due to Earth’s gravity is called g and is equal to 9.8 m/s2 at Earth’s surface. You can calculate the force of Earth’s gravity on an object at Earth’s surface using the object’s mass and this acceleration. The formula that expresses Newton’s second law is F = ma. If you use g as the acceleration, the formula for calculating the force due to gravity on a mass close to Earth’s surface becomes F = mg.
The force between the items grows as mass 1 increases. The force between the objects reduces if Mass 2 decreases.
What is gravitational force?An item with a larger or lower mass will exert a more or less gravitational pull. The gravitational pull between two objects varies depending on how close or far they are to one another.
The force between two items weakens the more apart they are from one another. (Newton's third law of motion) the forces are equal.
Four times as much power will exist between the spheres. The notebook has very little gravitational pull on you, the gravitational force.
Therefore, keep in mind that your motion is affected by the total force acting on you.

A

Subm
B
Nat is transported into the cell by active transport
с
The movement of glucose through the membrane requires ATP hydrolysis
D
Na transport out of the cell requires ATP hydrolysis
Answer:
The correct answer is - D . Na transport out of the cell requires ATP hydrolysis
Explanation:
Sodium-ion moves or transported from the inside of the cell to the outside the cell by the process called active transport. Active transport takes place takes place when the movement is against the concentration gradient to a higher concentration area through the cell membrane.
Active transport requires energy in order to transport the molecules or ions from low concentration to high concentration. In sodium-potassium pump get the energy from the hydrolysis of the ATP.
The given diagram represents the transport of sodium out of the cell using active transport. Active transport utilises the energy or ATP released during respiration. The correct answer is that sodium is transported out of the cell requires ATP.
Active transport is defined as the transport in which molecules move from lower to higher concentration, against the concentration gradient. The active transport requires the hydrolysis of energy to move across the cell. The sodium-potassium pump follows the active transport, such that:
The pumping of ions against the concentration gradient requires the addition of energy. The high-energy molecule is used to facilitate the active transport of sodium ions during the sodium-potassium pump.Therefore, the image represents the sodium is transported out of the cell by active transport.

Answer:
C
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
