Differences in traits such as hair texture are determined by differences in:_____.
a. the location of sugar groups in DNA
b. the sequence of nucleotides in DNA
c. the number of nitrogenous bases in DNA
d. the molecule attached to the phosphate in DNA
Answer. C-the number of nitrogenous based in DNA.
Explanation:
Differences in traits such as hair texture are determined by differences in the sequence of nucleotides in DNA.
What is DNA?
Deoxyribonucleic acid, also known as DNA, is a large molecule that houses our distinct genetic code.The four fundamental "bases" or "building blocks" of DNA are adenine (A), cytosine (C), guanine (G), and thymine (T) .The genome instructions are formed by the arrangement, or sequence, of these nucleotides.A two-stranded molecule, DNA.DNA is shaped like a twisted ladder and has a special "double helix" form.Traits controlled by nucleotide sequence:
A section of DNA known as a "gene" is used as a template during gene transcription to produce messenger RNA, which is then utilized as a template to produce proteins during the translation process.
The sequences of the proteins produced by transcription and subsequent translation are determined by the nucleotide order in a gene.
Both structural and enzymatic proteins have a major role in determining the phenotypic characteristics.
In conclusion, variations in the SEQUENCE of nucleotides in DNA are what cause variations in traits like hair texture.

how many pgal molecules will it take to make one molecule of glucose
PGAL molecules will it take to make one molecule of glucose Calvin Cycle (light independent reactions).
Phosphogly ceraldehyde, or PGAL for short, is a 3-carbon compound as you can see from the diagram of its chemical shape. as soon as PGAL has been made, its carbon atoms are used to synthesize different natural compounds, which are crucial for the increase and survival of plants.
The response is catalyzed via the enzyme ribulose bisphosphate carboxylase/oxygenase (Rubisco). The six-carbon intermediate reacts with water and decomposes into two identical 3-carbon molecules called phosphoglycerate. those, in turn, react with ATP and NADPH to produce PGAL molecules.
One turn of the Calvin Cycle fixes 3 CO2 C O 2 molecules and generates 1 molecule of phosphoglyceraldehyde (PGAL). So, whilst 54 molecules of CO2 C O 2 enter the Calvin Cycle, 18 molecules of phosphoglyceraldehyde (PGAL) also called glyceraldehyde-3-phosphate (G3P) will leave the cycle.

When two mechanical waves have a displacement in the same direction, and they overlap,
what will the resulting wave look like?
When two mechanical waves have a displacement in the same direction, and they overlap, then the resulting wave would have a higher amplitude or displacement compared to the original waves. This is referred to as constructive interference.
Any position along the medium where the two interfering waves have a displacement in the same direction will experience constructive interference. Because both waves in this instance have an upward displacement, the upward displacement of the medium is higher than the displacement of the two interfering pulses. Any site where the two interfering waves are moved upward will exhibit constructive interference. But it can also be seen when the displacement of both interfering waves is downward. This is seen for two downwardly displaced pulses in the picture below.

Two lizard species both forage in fig trees in the Caribbean. To study potential competition between the species, you observe a sample of both species, observing the fraction of time they spend in the upper half and bottom have of the trees, as well as the fraction of their diet comprised of insects vs. fruit. Below are your data.
Answer choices:
A. Character displacement is occurring between these two species
B. Resource partitioning is occurring between these two species
C. These species appear to have a mutualistic relationship
D. These species appear to have a parasitic relationship
E. Competitive exclusion is likely to occur where these species are found together
Resource partitioning occurs when two species that share the same niche, make use of resources differently in order to avoid competition. Option B) Resource partitioning is occurring between these two species.
What are competitive exclusion, resource partitioning, and character displacement?Intra- or interspecific competition is an ecological and evolutive process very common in nature.
Competition between different species might be due to the same resource use (food, territory, shelter, etcetera). When a resource is useful for two or more species, and is limited, they compete to gain it.
The principle of competitive exclusion states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource.
When two competing species coexist, this is because of resource partitioning or niche differentiation.
Differentiation of effective niche is closely related to character displacement.
Character displacement is the result of interspecific competition, in which two or more species that live in the same habitat manage to avoid competition by developing different traits.
Morphological divergence, or any adaptative trait development, fixated genetically, is the product of niche segregation.
Species tend to differentiate morphologically in the presence of strong competitors. Traits divergence favors coexistence in the same place.
In the exposed example, we can see that,
both species (A and B) spend most of their time in the upper part of the tree. species A mainly preys on insects, while species B mainly feeds on fruits.These populations can share the same niche because of resource partitioning. Most of them feed in the upper part, but to avoid competition, one population feeds on insects, and the other one feeds on fruits.
This resource partitioning might lead to the occurrence of character displacement related to the feeding and digestive apparatus and predation strategies. However, the table does not reflect this information.
The correct option is B. Resource partitioning is occurring between these two species.

Why is Mendel's model of genetics not the only model of inheritance?
Mendel's model of genetics is not the only model of inheritance, because may be another model, was also presented by another scientist.
How is Mendelian inheritance different from Non-Mendelian inheritance?The Mendelian quality is determined by dominant and receding alleles of one gene. On the opposite, non-Mendelian traits are not determined by dominant and relapsing alleles and can be governed by more than one gene. Non-Mendelian inheritance is any design in which traits do not segregate in accordance with Mendel's laws.
The genetic traits that follow the truth of Mendel's law are known as Mendelian inheritance while the genetic traits. Non-Mendelian genetics are inheritance motif that is different from Mendelian inheritance.
