Answer:
evolutionary developmental biology (evo-devo)
Explanation:
Evolutionary developmental biology (evo-devo) is a relatively new field of biology focused on the comparison of developmental processes between organisms in order to infer evolutionary relationships among species and understand such developmental mechanisms. This research area has shown to be very useful to understand how morphological evolution occurred. Moreover, evo-devo also shows how changes at the genome level can be translated into morphological and phenotypic changes among species/higher taxa. Evo-devo challenges the so-called 'gene-centered point view of evolution', which holds that adaptive evolution mainly operates by means of the differential survival of competing (selfish) genes.
A single gene mutation results from
Answer: DNA changes in one particular gene
Explanation:
Single gene disorders are caused by DNA changes in one particular gene, and often have predictable inheritance patterns. Over 10,000 human disorders are caused by a change, known as a mutation, in a single gene. These are known as single gene disorders.

Explanation:
Explain how genetic mutations may result in genetic and physical variations differences) within a population.
Answer:
The correct answer is - Mutations produce different versions of genes.
Explanation:
Mutations are the changes in the gene or DNA of an organism that leads to the production of different version of genes and proteins. Mutations result in genetic variation or physical variation within the population as it introduces new alleles in the populations.
Mutations introduce or remove various versions of genes called alleles within a population and increases genetic variation. These changes in the genes are the source for new genetic variation. Genetic or physical variation does not occur without mutations.

HURRY PLEASE I RLLY NEED THIS FOR THE MOST IMPORTANT TEST IM TAKING THIS YEAR. The diagram shows a toy car on a number line.
A line with arrowheads at both ends has ticks marks every 2 units. The tick marks for 0, 6, and 10 are labeled. A car sits above the tick mark for 2 with a dashed red line leading to the tick mark.
What is the position of the car?
–4
1
2
4
Answer:
The position of the car is +2 or simply 2
Explanation:
The position of an object is usually given from a reference position.
A number line is used to specify the position of the car in the given question.
A number line has numbers arranged on a straight line with positive and negative numbers found on both sides of zero serving at the center of the number line. Positive numbers are found to the right of zero on the number line while negative numbers are found to the left of zero onnthe number line.
In the given question, the number line has ticks marks every 2 units.
The car sits above the tick mark for 2 with a dashed red line leading to the tick mark.
Since the car is found to the right of zero on the number and sits above the tick mark for 2, the position of the car is +2 or simply 2

cual es la diferencia netre los cloroplastos y la cianobacteria si ambos son bacterias fotosinteticas???
Answer:
Encontré esto en un texto de microbiología, tal vez sea útil.
Explanation:
"Las cianobacterias y los cloroplastos de las plantas tienen ambos fotosistemas, mientras que las bacterias fotosintéticas anoxigénicas sólo utilizan uno de los fotosistemas. Ambos fotosistemas son excitados simultáneamente por la energía luminosa. Si la célula requiere tanto ATP como NADPH para la biosíntesis, entonces llevará a cabo una fotofosforilación no cíclica".

De acuerdo al siguiente enunciado, responda: "sus funciones son similares; difieren en su origen embrionario y en su plan de construcción".
Answer:
el enunciado hace referencia a estructuras análogas
Explanation:
La estructuras análogas (por ejemplo, órganos, tejidos, etc) son aquellas que cumplen la misma o similares funciones pero que poseen un origen evolutivo distinto (es decir, no comparten un antepasado común) y son producto de la convergencia evolutiva. Por el contrario, estructuras homólogas son aquellas que se caracterizan por tener un origen evolutivo común (comparten un antepasado común), independientemente de la función que cumplan. Las estructuras análogas se caracterizan por tener diferentes orígenes embrionarios y planes de construcción distintos (es decir, las células que dan origen a este tipo de estructuras son de linajes diferentes). Un ejemplo bien conocido de estructuras análogas son las alas de mariposas y murciélagos, las cuales cumplen la misma función pero no derivan de un antepasado común.

Describe what occurs in each phase of mitosis.
Prophase -
Metaphase -
Anaphase -
Telophase -
Cytokinesis -
( please do not plagiarize )
Answer:
prophase- the first phase of mitosis, in which the chromatin in the cell coils into chromosomes that can be seen
metaphase- the second phase of mitosis, in which the chromosomes that were doubled become attached to the spindle fiber by their centromeres
anaphase- the third phase, where centriomeres are split apart and sister chromatids are pulled to opposite poles of the cell
telophase- the final stage of mitosis, in which sister chromatids are separated and contain identical copies of DNA
cytokinesis- a process the divides the cytoplasm and plasma membrane of a cell, resulting in two identical cells that contain their own DNA, nucleus, nuclear membrane, and plasma membrane

In 1838 botanist Matthias Schleiden determined that all plants are composed of cells. In 1839 anatomist Theodor Schwann proposed that all animals are composed of cells. In 1855 biologist Rudolph Virchow added to Schleiden's and Schwann's observations and proposed that all living things are composed of cells. Which statement is also part of Virchow's cell theory?
Answer:
This question lacks options, the options are;
A. All cells have a cell wall.
B. All cells arise from pre-existing cells.
C. All cells are capable of photoshynthesis.
D. All cells can develop into any other type of cell.
The answer is B.
Explanation:
The widely accepted universal cell theory is known to be contributed to by three scientists viz: Matthias Schleiden, Theodor Schwann and Rudolph Virchow.
As rightly stated in this question, Botanist Mathias Schleiden and Zoologist Theodor Schwann proposed that plants and animals are made up of cells in the year 1838 and 1839 respectively. However, in 1855, biologist Rudolph Virchow expanded the cell theory by adding that all living things are composed of cells and that these cells arise from pre-existing cells.
The collaboration of these three scientists brought about the cell theory that states:
* Cells are the basic unit of all living things.
* All living things are made up of one or more cells.
* All cells arise from pre-existing cells.
