How is translation different in prokaryotes and eukaryotes?
In prokaryotes, the translation of mRNA occurs while it is being transcribed.
In prokaryotes, pre-mRNA translation before transcription occurs within the cell.
In prokaryotes, reverse transcriptase simultaneously translates and transcribes mRNA.
In prokaryotes, functional mRNA allows for translation to be skipped, and proteins are made during transcription.
Answer: translation can begin during transcription
Explanation: In prokaryotes there is no nucleus and no separation of these processes.

selection
Environmental conditions often favor one__
over another.
Answer:
phenotype or trait
Explanation: if it is really cold a mouse with thicker fur (phenotype) will do better
Environmental conditions often favor one selection over another.
In the context of evolution, selection refers to the process by which certain traits or characteristics become more or less common in a population over time. This process occurs due to environmental conditions that favor certain individuals with advantageous traits, leading to their increased survival and reproduction.
For example, consider a population of birds living in a forest with two distinct color morphs: light and dark. If the forest becomes darker due to increased tree cover, the dark-colored birds might be better camouflaged and have a higher chance of surviving and reproducing. Over time, the proportion of dark-colored birds in the population would increase, as they have a selective advantage in the new environmental conditions.
Similarly, if the forest becomes lighter, the light-colored birds may become more successful in avoiding predation and finding mates. In this case, the environmental conditions would favor the light-colored birds, leading to an increase in their frequency within the population.
Therefore, the term "selection" refers to the process by which environmental conditions favor certain individuals or traits, resulting in changes in the frequency of those traits within a population over time.

What is the difference between an instinct and a learned behavior?
Answer:
See below.
Explanation:
The major difference between an instinct and a learned behavior is how it was picked up. An instinct is something that you're born knowing (think of being programmed to do certain actions or display specific behaviors.) An example of this would be how homing pigeons are "wired" and remember their home when they migrate. A learned behavior, on the other hand, is something you have to learn as you don't have a certain behavior, skill, etc. This can be a language, how to walk/talk, personality, likes and dislikes, learning how to read, write, or learn information. So right now, learning about this is displaying a learned behavior (being able to process information and read). :)
When listing the levels of organization in organisms from least complex to most complex, which level is just below
organs in complexity?
O cell

Answer:
tissue
Explanation:
The level of organisation of life in biology refers to an hierarchical classification of how organisms are formed beginning from the simplest unit of life, which is a CELL. The cell is the basic unit of life and it represents the least complex level of organization.
However, a collection of cells with similar functions give rise to a TISSUE. Tissues give rise to ORGANS. Organs give rise to ORGAN SYSTEMS. Organ system gives rise to ORGANISM. The order of this hierarchy from the least to most complex is as follows:
Cell → Tissue → Organ → Organ system → Organism
According to the question, the level that is just below organs in complexity is TISSUE.

In cats, coat color is determined by allelic variation at a single autosomal locus, with black fur dominant to white fur. Two heterozygous black cats are mated. What would be the probability of the following combinations of offspring in a litter of eight kittens?
a) All with black fur.
b) Five with black fur and three with white fur.
c) At least three of the kittens having white fur.
d) The firstborn kitten with white fur, and among the remaining seven kittens, three with black fur and four with white fur.
Answer:
Explanation:
Two Heterozygous Black cats mated
let 'B' be for the Black allele and 'b' for the white allele
hence the mating will be : Bb * Bb = BB , Bb , Bb, bb, BB, Bb, Bb, bb
a) Determine the probability that all kittens out of 8 kittens are black
That means the kittens will have 'BB' or 'Bb' alleles
probability of Black fur = 3/4
b) probability of 5 black and 3 white
probability of black = 3/4
probability of white = 1/4
hence probability of 5 black = 3/4 * 5 =

In Drosophila, the dominant allele Cy (Curly) results in curly wings. The cross Cy/ x Cy/ (where represents the wildtype allele of Cy) results in a ratio of 2 curly : 1 wildtype F1 progeny. The cross between the curly F1 progeny also gives a ratio of 2 curly : 1 wildtype F2 progeny. How can this result best be explained
Answer:
d
Explanation:
Using a Punnet square to represent the given information
The cross between Cy + and Cy + can be computed as:
Cy +
Cy Cy Cy Cy +
+ Cy + ++
From what we see above, it is above that the ratio of Curly to wildtype is in the ratio of 2:1
This illustrates that the genotype Cy Cy is lethal. This is explained when two curly F1 are crossed which resulted in the same ratio.
Hence, the inheritance of Cy/Cy is fatal.

Which of the following best describes the relationship between DNA and proteins? (I accidentally clicked "D." im not sure if it is the answer.)
Answer: A
Explanation:
The central dogma of biology is that dna makes rna which makes protein
The relationship between DNA and proteins is that the DNA indirectly codes for the amino acid sequence of a protein. Thus, the correct option is A.
What is Translation?Translation can be defined as the process by which a cell makes the proteins using the genetic information which is carried in the form of messenger RNA (mRNA) molecule. The mRNA molecule is made by copying the DNA molecule, and the information which it carries tells the cell about how to link amino acids together in the form of polypeptide chains to form proteins.
The mRNA molecule is formed from DNA molecule through the process of transcription. These mRNA molecule synthesize protein molecules.
Therefore, the correct option is A.

Fungi are described as eukaryotic, non-vascular, non-motile and heterotrophic organisms which can be unicellular or filamentous. They reproduce by means of spores which exhibit the phenomenon of alternation of generations. Fungi lack chlorophyll and therefore cannot photosynthesize.
Fungi are classified in four divisions such as the Chytridiomycota (chytrids), Zygomycota (bread molds), Ascomycota (yeasts and sac fungi), and the Basidiomycota (club fungi).
Thus, Fungi produces spores containing hyphae and a fruiting body. So, the correct options are A, C and D.
