Answer:
A. Plants
Explanation:
Nitrogen fixation is one of the processes involved in the NITROGEN CYCLE. It is the process whereby atmospheric nitrogen (N2) is converted into nitrogenous compounds such as ammonia, nitrates by certain nitrogen-fixing bacteria such as AZOTOBACTER.
The nitrogenous compounds which nitrogen fixation converts N2 into are in a form that PLANTS can use. Plants cannot utilize nitrogen gas, hence, the importance of this conversion into a form that plant can make use of.

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.

If a family has 10 children that are all blue eyed, what is the most likely genotypes of their 2
parents?
Explain.
Answer:
Most likely the parents are both has blue eyes but that's phenotype s their genotype would be bb or blue/blue because blue eyes are a recessive trait and it would be highly unlikely for all ten children to have blue eyes if this genotype were not the case (likely about 50% would not have blue eyes if the genotype was anything else but recessive blue and recessive blue)

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

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 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.

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.
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.

Explanation:
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.
