3. Darwin surmised that all life on Earth was connected, like branches on a tree of life. What would the trunk of this tree represent?
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

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.

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.
Which sex chromosome determines the sex of a baby?
Explain your answer.
Answer:
Girls have two X chromosomes and boys have chromosomes (XY).
Explanation:
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.
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.

What causes cells in living organisms to be different from one another?
O A An organism evolves new cell types in response to its environment
O B. The brain of an organism sends a signal to its cells to differentiate when the organismis in danger.
O c The DNA of an organism moves from one cell to another, allowing different cells to have different functions
O D. An organism expresses different genes at different times in development, causing cells to be specialized
Explanation:
The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.
a_fault is from the hanging wall drops down
Answer:
If the hanging wall moves down relative to the footwall, the fault is a normal fault. Normal faults are caused by tensional stress, or stress that pulls rocks apart
Explanation:
what determines the function of a protein
Answer:
The sequence of amino acids. - The three-dimensional shape of the folded protein. - If the coding sequence has a mutation that leads to a change in the amino acid sequence, the protein may have a different three-dimensional shape, reducing its activity.

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.
