How did the insertion of a nucleotide in a DNA sequence result in a phenotypic change in an organism

Answers

Answer:

if the nucleotide insertion occurs within the coding region of a gene (frameshift mutation), then it will change the open reading frame (ORF) of the resulting protein and thus also will alter the phenotype of the individual  

Explanation:

A mutation is any change in the DNA sequence of the genome of a cell/organism. A point mutation is a genetic mutation where a single nucleotide is inserted, deleted or changed from the original DNA sequence. The insertion of a single nucleotide in the coding region of a gene is called frameshift mutation since this nucleotide base shifts the way the DNA sequence is read. A frameshift mutation changes the meaning of the codons that follow the inserted nucleotide base and thereby protein function is generally lost, thereby also affecting the resulting phenotype associated with this protein.


Mientras se calienta una solución en un vaso de precipitados, ¿cuál es el
equipo de seguridad apropiado para tener en el banco?

Answers

Answer:

Fire extinguisher.

Explanation:

Fire extinguisher is the appropriate safety equipment to have at the side of the baker while heating a solution in a beaker because sometimes the solution catch heat due to reactions with flammable liquids which leads to big incident so in this case fire extinguisher can avoid such type of incident by turn off the heat due to the gas present inside the container of fire extinguisher so this safety equipment is necessary at the side of the reaction.

One important way in which the flow of energy through ecosystems is different from the cycle of matter

Answers

Explanation:

As energy moves through an ecosystem, it changes form, but no new energy is created. Similarly, as matter cycles within an ecosystem, atoms are rearranged into various molecules, but no new matter is created. So, during all ecosystem processes, energy and matter are conserved.

Answers

Explanation:

Both the endocrine and nervous systems use chemical signals to communicate and regulate the body’s physiology. The endocrine system releases hormones that act on target cells to regulate development, growth, energy metabolism, reproduction, and many behaviors. The nervous system releases neurotransmitters or neurohormones that regulate neurons, muscle cells, and endocrine cells. Because the neurons can regulate the release of hormones, the nervous and endocrine systems work in a coordinated manner to regulate the body’s physiology.

The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called... * 1 point

Answers

Answer:

The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called phylogenetic tree

Explanation:

The phylogenetic tree is composed of,

• Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.  

• Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.  

• Root → This is the older common ancestor that all lineages share. The first one in the tree.  

Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.

Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.  

There are also different phylogenetic relationships between lineages.  

• Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.

• Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.

• Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.

nonsister chromatids from each homologous chromosome of a tetrad are exchanged, resulting in new combinations of alleles.

Answers

Answer:

genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles.

During crossing-over, the genetic material is exchanged between non-sister chromatids, resulting in new combinations of alleles. Thus, the correct option is C.

What is Crossing-over?

Meiosis is the cell division in which crossing-over takes place. Crossing-over results into formation of recombinants with genetic material which is different from the parental cells. Crossing-over takes place in the pachytene stage of prophase I of Meiosis I. This is responsible for the production of variations in the organisms.

Crossing over or chromosomal crossover is the exchange of genetic material during the sexual reproduction between the non-sister chromatids of two homologous chromosomes which results in recombinant chromosomes.

Therefore, the correct option is C.

Answers

Answer:

natural selection acts by differential survival and reproduction

Explanation:

According to the evolutionary theory proposed by Darwin (1859), selection natural can be defined as the evolutionary mechanism of differential survival and reproduction by which individuals adapt and change over time. Natural selection states that individuals better adapted to their environments will have more chances to survive and reproduce, thereby having more chances to pass their genes to the next generation. Natural selection acts on any heritable phenotypic characteristic, while selective pressure is any environmental factor that influences an individual's survival/reproduction.
