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.

What are 2 pieces of evidence that support the Continental Drift Theory? Explain how they support the theory.
Answer:
Explanation: In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth's surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
The fit of the continents; the dispersion of ancient fossils, rocks, as well as highlands; and the positions of ancient climatic zones were all evidence for continental drift.
What is Continental Drift Theory?Continental drift was a groundbreaking theory that explained how continents shift position on the Earth's surface.
Alfred Wegener, a geophysicist and meteorologist, proposed the theory in 1912, but it was rejected by mainstream science at the time.
Plate tectonics caused continental drift over millions of years. Plate tectonics also explained how plate movement causes volcanoes and earthquakes, as well as how continent collisions create massive mountain ranges.
Continental drift was demonstrated by the fit of the continents, the dispersion of ancient fossils, rocks, and highlands, and the positions of ancient climatic zones.
Thus, these are the evidences that support the Continental Drift Theory.

An organism has three different versions of Gene Tyx- version a, b, and c. Determine the inheritance pattern of this trait. Then list below all of the different genotypes that an organism with this gene could have
Answer:
The inheritance pattern of these traits will be independent. However, it will depend on the factor that which trait is dominant or recessive. It might also show incomplete dominance.
The different genotypes that organisms of this population might have are aa, ab, ac, bb, bc , cc. If neither of the alleles are completely dominant over the other, then incomplete dominance might exist for such genes.

An important piece of information in the management of a person infected with a chronic virus such as HIV is his/her "viral load" or how many virus particles can be detected. If before PCR, a patient had a viral load of 1.6 x 104 viral particles. What would be the amount of DNA in the sample after the completion of the first PCR cycle?
Answer:
the answer is 3.2 x 10⁴
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology to exponentially amplify a specific DNA sample from a small amount of DNA. For this purpose, the PCR technique uses: 1- a DNA polymerase enzyme in order to synthesize new DNA copies and 2- one pair of DNA oligonucleotides (primers) which are complementary to the ends of the target DNA sequence. During each round of PCR, the double-stranded DNA template is unwound and each strand is used to synthesize a new DNA strand, thereby forming two new double-stranded DNA molecules. In consequence, each round of PCR doubles the amount of DNA.
chemical composition of the Rough endoplasmic reticulum
Answer:
The rough endoplasmic reticulum consists of two dimensional flattened sacs formed from phospholipids and ribosomes.
Explanation:
Genes within DNA are expressed through transcription and translation of the genetic code.
The rough Er contains important machinery in gene expressions, Ribosomes embedded in a lipid membrane. These are small sub cellular organelles that carry out a specific function of protein manufacturing and modulation. They contain the translocon complex, integral to the translation process
The endoplasmic retuculum consists of folded phospholipid membrane sheets or cisternae- these are mainly two dimentional, and form flat sacs.These provide small specific environments from the cytosol in the cytoplasm- they span the entire cytoplasm.
Which type of cells contain a cell wall?

Jackson uses a battery operated toothbrush that is rechargeable. What happens when Jackson plugs his toothbrush into an electrical outlet to recharge it?
Answer:
Explanation:
The type of battery that Jackson's toothbrush is using is a secondary cell; this is because it can be recharged (meaning the electrochemical reactions taking place in the battery can be reversed). Batteries generally work in such a way that, while using it, electrons move from the anode of the battery to the cathode. In primary cells, this process continues until there are no electron to be transferred from the anode to the cathode and then the battery "dies" and is disposed. But in a secondary cell, just like the battery of Jackson's toothbrush, when the battery is been recharged, the electrons start moving from the cathode back to the anode; which makes electrons available again in the anode for use.

An Earth scientist is testing how various soil mixtures affect plant growth. She begins with 10 soil types. For each mixture, she combines equal amounts of 2 soil types. How many soil mixtures must the scientist create in order to test all possible combinations of the 10 soil types?a. 20b. 45c. 55d. 90
Answer:
b
Explanation:
The correct answer would be 45.
Assuming that the 10 soils are each represented by A, B, C, D, E, F, G, H, I, J.
A can combine with 9 others as: AB AC AD AE A F AG AH AI AJ
B can combine as: BC BD BE BF BG BH BI BJ
C as: CD CE CF CG CH CI CJ
D as: DE DF DG DH DI DJ
E as: EF EG EH EI EJ
F as: FG FH FI FJ
G as: GH GI GJ
H as: HI HJ
I as: IJ
Adding all the combinations together = 45
In other words;
[tex]^{10}C_2[/tex] = [tex]\frac{10!}{(2!(10 - 2)!)}[/tex] = 45
The soil mixtures must the scientist create in order to test all possible combinations of the 10 soil types- b. 45.
Given
soil samples = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
each mixture must have two sample
SolutionWe have to mix 2 soils in equal amounts. Then, the total number of possible soil mixtures are:-1 and 2, 1 and 3, 1 and 4, 1 and 5, 1 and 6, 1 and 7, 1 and 8, 1 and 9, 1 and 10 = >92 and 3, 2 and 4, 2 and 5, 2 and 6, 2 and 7, 2 and 8, 2 and 9, 2 and 10 => 83 and 4, 3 and 5, 3 and 6, 3 and 7, 3 and 8, 3 and 9, 3 and 10 => 74 and 5, 4 and 6, 4 and 7, 4 and 8, 4 and 9, 4 and 10 => 65 and 6, 5 and 7, 5 and 8, 5 and 9, 5 and 10 => 56 and 7, 6 and 8, 6 and 9, 6 and 10 => 47 and 8, 7and 9, 7 and 10 => 38 and 9, 8 and 10 => 29 and 10 => 1Then Total mixtures possible are =

c. 12
Calvin cycle:
In Calvin cycle number of carbon atoms are constant in CO₂ and used to construct three-carbon sugars. This manner is fueled by, and established on, ATP and NADPH from the mild reactions.The Calvin cycle reactions occurs in three main stages: carbon fixation, reduction, and regeneration of the starting molecule.So, in the question it is asked how many G3P would be produced if there are 36 carbon dioxide that enters the Calvin cycle. Thus the answer is 12
In order for one G3P to go out the cycle (and move in the direction of glucose synthesis), 3 CO₂ molecules need to input the cycle, imparting 3 new atoms of constant carbon.

Answer: The question is incomplete and options are not given, here are the options.
A. Atricial
B. Precocial
C. Hyperbole
D. Hyperactive.
The correct option is precocial.
Explanation:
It is precocial because it is the ability of new hatched birds with full feathers and eye open to be able to move around and find food after been hatched from the egg. It is common in birds and it is gotten from Latin word called precoccous. Some newly hatched birds can be able to mobilise around minutes after hatching and search for food while some cannot move around minutes after hatching to search for food, this type of birds are called Altricial.
