Answer:
El árbol de la vida o árbol universal de la vida es una metáfora, modelo y herramienta de investigación que se utiliza para explorar la evolución de la vida y describir las relaciones entre organismos, tanto vivos como extintos, como se describe en un famoso pasaje de El origen de las especies (1859) de Charles Darwin.2

Girls have two X chromosomes (XX), and boys have one X and one Y chromosome (XY). Whether a baby will be a boy or a girl is determined at the time of conception.
which of the following are key elements of darwin's theory of evolution by natural selection?
Answer:
Independent assortment and crossing over contribute to diversity within a population's gene pool. These processes occur during meiosis and result in the recombination of DNA.

The three pillars of Darwin's theory of evolution are genetic variety, fitness, and adaptation. Overproduction and competition are other crucial components of this process.
What Darwin's theory of evolution by natural selection?Charles Darwin's theory of evolution is known as natural selection. Due to the limited supply of resources in nature, animals have inherited traits that aid in both survival and reproduction.
Typically, produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this Overproduction is that those people who have the highest level of environmental genetic fitness will have offspring who are better able to compete in that environment.
Therefore, Genetic variation, fitness, and adaption are all factors in Darwin's theory of evolution.Overproduction and competition are other crucial components of this process.

What is the significance of crossing over?
Answer and Explanation:
Crossing over is the switching of genetic material (DNA), which occurs in Prophase 1.
This all happens in Meiosis, which is the process of the formation of sperm and egg cells.
The paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.

Transcription is the process that must happen in order to make
Answer:
a protein
Explanation:
Transcription is one of the three main, necessary events needed for proteins to form in a cell. This happens when DNA is transcribed to mRNA. Thymine (T) is subbed in by Uracil (U), so when transcribing, A's turn into U's, not T's.
characteristics that scientists study to determine if a new species has been
discovered
Answer:
When ecologists travel to regions where they are not familiar with the plants and animals, they read field guides about the flora and fauna. Many of these guides have photographs, keys to species recognition, and descriptions of size, color, and general appearance.

In the eukaryotes

What does it mean to be in the same species
Answer:
organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
The planets, comets, and meteors of the solar system are held
(in orbit by the Sun's.
fa. Gravity
16 Spring force
I. Friction
d. Tension
Answer:
Gravity
Explanation:
Gravity keeps the planets, comets and meteors in orbit around the sun. The sun is bigger and heavier than other planets etc, this causes the planets to be pulled and kept in orbit around the sun.
