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.

When molecules are exposed to heat, they
A
stop moving completely.
B
begin to slow down.
C
start to move faster.
D
explode.
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.

g If you look carefully at this organism, you will not see any organs for gathering oxygen or releasing carbon dioxide or ammonia. There is no circulatory system. How does this animal perform these functions
Answer:
Simple unicellular organisms like Amoeba and some multicellular organisms like Hydra use their cell surface and skin for gaseous exchange with their environment.
Note: The organism in the question was not stated.
Explanation:
The complexity of an animal determines its metabolic needs, and hence, its requirement for specialized structures and functions.
Simple unicellular organisms are able to meet their metabolic needs such as gaseous exchange by simple diffusion through their cell surfaces. Such organisms include amoeba, paramecium, etc.
Some multicellular organisms lack specialized organs for nutrient transport and gaseous exchange such as hearts and blood vessels, etc. Example of such organisms are Hydra and Planaria. They have their cell surfaces in contact with the external environment, and thus use their skin for gaseous exchange by means of diffusion.
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

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]

This type of inheritance pattern shows BOTH traits in possible offspringand is not a blending or intermediate
phenotype.
O a. incomplete dominance
O b. dominant pattern inheritance
O c. complete dominance pattern inheritance
O d. codominance
Answer:
The correct answer is - d. codominance.
Explanation:
Complete dominance is the pattern of inheritance where one allele masked the other allele completely in a heterozygous condition. Incomplete dominance is a pattern of inheritance where both the alleles blend or form intermediate phenotype in heterozygous condition.
The codominance pattern of inheritance is similar to the incomplete dominance but instead of making a blend of both alleles, it expresses both alleles together in patches or pattern.
The type of inheritance pattern that shows BOTH traits in offspring and is not a blending or intermediate phenotype is CODOMINANCE.
In genetics, codominance refers to the phenomenon by which both parent phenotypes for a given trait are simultaneously expressed together in the offspring.
Conversely, incomplete dominance occurs when the phenotypes of the two parents are mixed in the offspring in order to create a new intermediate phenotype.
Finally, complete dominance refers to the inheritance pattern by which a dominant allele completely masks the expression of the recessive allele in offspring.
In conclusion, the type of inheritance pattern that shows BOTH traits in possible offspring and is not a blending or intermediate phenotype is CODOMINANCE.

In the essay box below, submit any observations you made, as well as the answers to the questions above. Then write a summary paragraph describing the effects of mass and distance have on the gravitational force between objects.
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.
What happens to the force between the two spheres of the same mass when the distance between the mass spheres is doubled?
What happens to the force between the two spheres of the same mass when the distance between the mass spheres is halved?
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.
