The change that is observed in a distribution curve for a trait affected by directional selection is that it shifts either to the right or to the left, which is the second option.
What is directional selection?Natural selection is process by which heritable traits conferring survival and reproductive advantage to individuals tend to be passed on to succeeding generations and become more frequent in a population.
Natural selection has the following types;
Directional selectionDisruptive selection Stabilizing selectionDirectional selection, is a type of natural selection in which an extreme phenotype is favored over other phenotypes. This causes the allele frequency to shift over time in the direction of that phenotype.
Therefore, the change that is observed in a distribution curve for a trait affected by directional selection is that it shifts either to the right or to the left.

PLEASE HELP! A flower has the genotype for red and white petals. Describe the offspring phenotype if the flower follows these inheritance patterns.
a. Codominant ? __________
b. Incomplete dominance? ___________
Answer:
Explanation:
Co dominant would give flower with red and white petals (heterozygous), whereas, incomplete dominance would sort of mix both the genotypes and give new color, in this case we will see a pink color for heterozygous genotype.
Why do the pocket mice in the dark lava environment have white underbellies?

It is most likely an adaptation or trait they have inherited from their parents.
what happens during translation?
a) each strand of DNA is used as a template to produce a complementary strand of DNA
b) each strand of DNA is used as a template to produce a strand of DNA with the same sequence as bases
c) each strand of DNA is used as a template to produce a complementary strand of mRNA
d) codons coded in the mRNA are used to produce a string of amino acids
During translation, codons coded in the mRNA are used to produce a string of amino acids. The correct answer is D.
Translation is the process in which the genetic information encoded in the mRNA molecule is used to synthesize a protein. It takes place in the ribosomes, where transfer RNA (tRNA) molecules carrying specific amino acids bind to the corresponding codons on the mRNA. The sequence of codons on the mRNA determines the sequence of amino acids in the resulting protein.
The process begins with the initiation stage, where the small ribosomal subunit binds to the mRNA and the initiator tRNA recognizes the start codon. Then, the large ribosomal subunit joins the complex, and the elongation stage begins.
During elongation, the ribosome moves along the mRNA molecule, reading each codon and bringing in the appropriate tRNA molecule with its attached amino acid.
The ribosome catalyzes the formation of peptide bonds between adjacent amino acids, forming a growing polypeptide chain. This process continues until a stop codon is reached, signaling the termination stage and the release of the completed protein.
In summary, translation involves the decoding of the mRNA sequence by ribosomes, using tRNA molecules and their associated amino acids to assemble a polypeptide chain according to the instructions carried by the codons on the mRNA. Therefore, the correct answer is D.

If dna of a particular species was analyzed and it was found that it contains 27 percent a, what would be the percentage of c?.
DNA of that particular species contains 23 % of C
How can we calculate the percentage of DNA?Adenosine (A) is complimentary with Thymine (T), that means that there is 27% of A + 27 % of T = 54%
To calculate the percentage of Cytosine (C) we need to know that C and Guanine (G) are also complementary. That means that the remaining 46% is half C and half G.
Therefore, the percentage of C is 23%.

Which stage of demographic transition does this describe?
a. Stage 1
b. Stage 2
c. Stage 3
d. Stage 4
Answer:
A) Stage 1
Explanation:
Demographic transition has to do with the changing pattern of factors that impact population such as birth rates, death rates as the population moves from regime to regime. The transition is in four stages:
Stage 1: which is characterized by high high birth and death rates. also known as pre-transition stage.Stage 2: Characterized by falling death rate but continued high death rate. Also known as early transition stage.Stage 3: characterized by a decline in birth rate and deceleration of population growth. It is also known as late transition period.Stage 4: Characterized by low birth and death rate. Negligible population growth. Also known as post-transitional period.True or false Ozone is a gas made up of four oxygen atoms

Answer:
A. putting smoke into air
Explanation:
Can't be B. because they are harming the water from dangerous chemicals. Not C. because they are harming the atmosphere from dangerous chemicals. Not D. because phospate is used in fertilisers and if that gets in water it will cause algae bloom a sudden growth in algae which will block light from coming in the river or lake and so hydrophytes(aquatic plants) will die and fish will not get any oxygen so will also die.
