Explanation:
18. Brayden is trying to figure out how petal shape is determined in two different roses. In the pink
rose, the copies of the gene are the same as each other. In the yellow rose, the copies of the gene are
different from each other. How does this affect how many types of proteins there are in each petal
cell?
a
The pink rose has one type of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
b
The pink rose has one type of protein for the petal shape feature. The yellow rose has one
type of protein for the petal shape feature.
с
The pink rose has two types of protein for the petal shape feature. The yellow rose has two
types of protein for the petal shape feature.
d
It is impossible to say anything about proteins from the given information.
Answer:
c
Explanation:
they would have diffrent gene versions and protines to get their colors
In the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.
What is the petal shape dependent on?Generally, the characters are dependent on the genes that are present in the DNA; either the gene variants, such as the alleles, show pure dominance or they combine to produce the effect, and here the pink rose petal has the same alleles so they will express the single protein while the yellow has different alleles so it has the chance of the two proteins.
Hence, in the pink rose, the copies of the gene are the same as each other, while the yellow rose has different copies, so it is concluded that the pink rose has one type of protein for the petal shape feature, while the yellow rose has two types of protein for the petal shape feature, as present in Option a.

16. The substances that are reabsorbed did not diffuse (move) from the nephron bowl into the
renal vein cup. You needed to use lots of energy to make reabsorption happen. Which
process do you think the kidney uses to transport these substances from the nephron to the
renal vein-active transport or diffusion (passive transport)? Explain your answer.
Answer:
Active transport.
Explanation:
The kidney uses active transport to move these substances from the nephron to the renal vein because these substances did not moves from the nephron bowl to the renal vein through simple diffusion so for this purpose active transport is used in which energy is spent in order to move the substances from one region to another so we can say that kidney must use active transport to move reabsorbed substances from the nephron to the renal vein.

Which is a characteristic that distinguishes members of the
plant kingdom from members of the animal kingdom?
Select one:
A. Plants store genetic information in the nucleus of their cells
B. Plants are motile primary consumers
C. Plants are multicelular
D. Plants are autotrophic
Answer:
D. Plants are autotrophic
Explanation:
Both plants and animals are eukaryotic, meaning they contain a nucleus with genetic information, so that crosses out A. I don't know what motile primary consumers are. Assuming, they're primary consumers, primary consumers are those that eat producers, so in this case, this would elminate B. Both plants and animals are multicellular. Plants ARE autotrophic, meaning they produce their own food. Animals, however, have to get their own food, either by hunting or scavaging.HELP ASAP!!!
What concept does Hubble's Law most concern?
A. energy lost over time across the universe
B. growing distance between galaxies
C. how stars recycle energy and matter
D. how the universe will eventually end
Hubble's Law most concern with growing distance between galaxies. Thus option B is correct.
What is Hubble's Law ?Hubble’s law refers to the observation in physical cosmology where the movement of galaxies from the Earth at a speed that are proportional to their distance.
The velocity of the galaxy which is called as the redshift.
This laws study physical cosmology and is also known as Hubble-Lemaitre law.
After measuring recession velocity one can determine the distance of the galaxy from us by using Hubble’s equation.
Some limitations are; due to intrinsic motion of galaxies, observed velocity gets influenced and Galaxy orbit due to gravitational movements.
Hubble constant is another unit of measurement, which is used for description of the expansion of the universe. It is 160 km/s per million-light-years.
Thus option B is correct.

Two distinct bands appear in a single lane at the completion of an SDS-PAGE analysis of an unknown protein. Select one: a. These bands represent two subunits of a homodimer. b. Each band represents a different sized subunit of a multimeric protein. c. Each band represents a protein subunit with different charge to mass ratio. d. These bands represent two subunits of a heterodimer. e. These bands represent two separate subunits of identical size.
Answer:
b. Each band represents a different-sized subunit of a multimeric protein.
Explanation:
SDS-PAGE analysis allows the separation and discrimination of proteins according to their molecular weight. The technique separates proteins in an electromagnetic field.
The SDS-PAGE technique makes proteins move in solid support -gel- by the action of the electric field. The distance reached by each protein is proportional to their molecular weight. The protein separation from a mixture results in bands that reflect their size.
SDS is a detergent that denaturalizes the protein and sets a relation charge size, such as that the motion of the protein in the gel is proportional to its weight. The bigger the protein is, the stronger interaction with the polyacrylamide gel there will be. The speed of displacement in the electromagnetic field is inversely proportional to the protein size.

Complete question:
Scientists have proposed more than two dozen ways to define species. One commonly used definition, called the biological species concept, holds that populations belong to the same species if they can contribute genes to a common gene pool. Reproductive barriers block gene flow between different species. Gene flow between populations tends to hold the gene pool of a species together.
Part A - Comparing species definitions
Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the morphological species (morphospecies) concept.
Drag each characteristic to the appropriate bin based on the species concept(s) to which it applies → You will find this in the attached files
Answer:
Not applicable for extinct species → Biological Based on evolutionary history → Phylogenetic Relies on similarities in structure → Morphological Accommodates asexual reproduction / Species acceptance criteria can be subjective → Morphological and PhylogeneticUsed by scientists in classification → Morphological, Phylogenetic, and BiologicalExplanation:
The biological concept states that species are population groups that -in a real or potential way- can mate and reproduce, but are reproductively isolated from other groups.
Individuals belonging to a species cannot reproduce with members of other species.
This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.
Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.
Finally, this concept is not adequate concerning hybridization zones, something to be expected considering evolutionary processes. This is the reason why it has been less accepted by botanists, as some plant species hybridize with other species.
The phylogenetic species concept defines species on a determined time and through time, and these are the horizontal and vertical species concepts, respectively. The species group is considered to be the less inclusive monophyletic group.
According to the phylogenetic concept, a species is a monophyletic group whose organisms share synapomorphies.
The establishment of species relies on molecular markers.
The morphological species concept defines species according to the shared morphological characteristics shared by all the members of the species. It is a descriptive method to separate species.
When a group differs considerably at a morphological level from another group, it is defined as a different species.
Some limitations might emerge from this species concept. It does not consider variability among individuals,
Individuals of the same species might be polymorphic, exhibiting morphological differences between organisms. These individuals would be considered to be different species following the morphological concept. Some different species might be morphologically similar, despite being different. These species might be considered as one following the morphological concept.DNA: TAC GCG TAC CGG ATC

In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codiminant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes.
O only
A or B only
A, B or O only
A, B, AB, or O
Please explain, also this is not a test its a test PREP
Answer:
D. A, B, AB, or O
Explanation:
We can start by visualizing all the possible genotypes of the offspring by drawing a Punnett square, which is a visual representation of the different possible combinations of alleles:
Individual 1 = AO, Individual 2 = BO
A O
B AB BO
O AO OO
Here we can see that there are 4 possible genotypes: AB, BO, AO and OO based on the alleles of the parents. Now we can match the genotypes to phenotypes to answer the question:
A and B are codominant, meaning that both will be expressed equally if both are present. Therefore the genotype AB will result in an AB phenotype.
Next, since A and B are both dominant over O, they are the alleles that will be expressed in the phenotype if paired with an O. This means that the genotype AO will result in an A phenotype, and likewise, genotype BO will result in phenotype B.
Finally in the genotype OO, although O is a recessive allele, there are no dominant alleles here to mask them, therefore O is expressed in the phenotype.
Hence, from the genotypes AO and BO, the possible offspring genotypes are AB, BO, AO and OO, translating to the possible phenotypes: A, B, AB or O.
