Which sentence best describes evolution?
Changes in genetic structure of a population occur over time.
Individuals inherit different characteristics.
Populations remain unchanged over time.
An individual grows and changes during its lifetime.
Answer:
changes in genetic structure of a population occur over time.
Explanation:
cuz that's how evolution be working
The option (A) is correct. The best sentence best describes the evolution is changes in genetic structure of a population occur over time.
What is evolution?Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.
Moreover, evolution is the change in heritable traits of biological populations over successive generations. Evolutionary processes give rise to diversity at every biological organization level. All life on earth shares a common ancestor known as the last universal ancestor.
Therefore, evolution is important because it explains how life developed on Earth and how different species are connected. The evolutionary linkages aid in the addressing of biological challenges, as well as the diversity of life.

Which of the following cell(s) is the end product after Meiosis I?
1)two diploid daughter cells
2)one diploid cell
3)two haploid daughter cells
4)one haploid cell
Answer:
C IS THE ANSWER, YOU GOT IT CORRECT
Explanation:
In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent.

What does the codon sequence on the mRNA strand determine?
A. The amino acid sequence of the polypeptide
B. The signaling sequence
C. The gene sequence of the DNA
D. The codon that is signaled
The amino acid sequence of the polypeptide is determined by the codon sequence on the mRNA strand. Therefore, option (A) is correct.
What is a codon?The genetic code is a system of principles that all living cells follow in order to decipher the information that is contained inside their genetic material and turn it into proteins.
The genetic code is comprised of a set of three-letter combinations of nucleotides known as codons. Each codon is associated with a particular amino acid or a stop signal. In 1961, Francis Crick and several of his colleagues were the first people to formally articulate the idea of codons.

Enzymes speed up reaction rates by changing...
activation energy.
hydrogen bonds.
pH.
substrates.
Enzymes usually speed up the reaction by changing activation energy. The correct option is A.
What is activation energy?In chemistry, activation energy is the minimum amount of energy to activate molecules or atoms to the point where they can cause chemical transformation or accessible and usable.
Heating is generally the source of activation energy, with reactant molecules absorbing thermal energy from their surroundings.
The activation energy is determined by the nature of the chemical transformation, not by the relative energy states of the reactants and products.
As the temperature rises, molecules will move and collide more frequently. Additionally, the molecules carry more kinetic energy.
As a result, as temperature rises, so does the proportion of collisions that can overcome the activation energy of the reaction.
Enzymes typically accelerate reactions by changing the activation energy.
Thus, the correct option is A.

Explain the disadvantages and advantages of each type of cell division.
Answer:
advantage-this is the final separations of the already duplicate molecular units, involving chromosomal assortment and cytoplasm decisions. all eukaryotic cells undergo mitotic decision while gemetes undergo meiotic division
The advantages of mitotic division:
It provides growth and development of the body.Dead cells of the body are removed or replaced.It mediates the equal distribution of chromosomes. Repair of the body takes place by the addition of new cells. What are the disadvantages of mitosis?The disadvantage of mitosis is that it involves a little genetic variation among the cells which induces the risk for the same diseases or disorders that are already occurred in the existing cells.
The advantages of the meiotic division:
It increases the genetic variations in the population of organisms from one generation to the next. Gametes are produced by meiosis.The disadvantages of the meiotic division:
It lacks the pace at which an organism can divide.It always requires two gametes.Therefore, it is well described above.
