Explain the evolution of altruism.

Answers

Answer 1

Answer:

Altruistic behavior, such as sterile worker ants caring for the offspring of their queen, evolves only between related individuals through what is known as kin selection — or so many evolutionary biologists have thought since the 1960s.

Organelles are microscopic in nature. Just like we have various organ parts in the human body that performs several body functions, so also do we have various organelles in a cell that carry out specific functions within a cell.

Organelles which can be referred to as "little organs" include the following: mitochondrion, nucleus, lysosomes, ribosomes, chloroplasts and so on.

mapa mental sobre El origen de las especies

Answers

El origen de las especies, cuya primera edición apareció en 1859, es el libro más conocido de El biólogo británico Charles Darwin. En el libro, Darwin expone su teoría de la evolución:

Afirma que toda la vida en la Tierra tiene un ancestro común. Que la selección natural es el mecanismo principal para la evolución de las especies.

El libro está considerado como una de las obras científicas más importantes de la historia. Causó revuelo en el momento de su publicación porque atribuyó la riqueza de la forma de vida en la Tierra a un proceso mecánico más que a una inteligencia sobrenatural. Es cierto que otros habían sugerido previamente que podría haber cosas como la evolución o la selección natural, pero "El origen de las especies" es el primer trabajo que extrae la mayor consecuencia de estos conceptos.

This indicates that: Group of answer choices A) Aspects of evolution are constantly being challenged and explored in light of new evidence. B) Gaps in the fossil records will never allow us to fully understand evolution. C) Scientists studying evolution typically present ideas with very little evidence, leaving it to others to find proof of their ideas. D) Much of the science of evolution is based on speculation that can easily be changed when scientists think of new ideas.

Answers

Answer:

Aspects of evolution are constantly being challenged and explored in light of new evidence

Explanation:

The whole idea of evolution has to do with the fact that organisms developed into their present form from simpler life forms. According to Oxford dictionary, evolution is; ''the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.''

Evolution depends on evidence from fossil records. Evidences that support the theory of evolution continue to be amassed as science advances. Hence, aspects of evolution are constantly being challenged and explored in light of new evidence.

For this reason, the evolutionary history and development of whales is being hotly debated and there has recently been a major shift in our understanding of the processes used to detail whale evolution.

Why would AZT be a poor candidate to inhibit SARS-CoV2?

Answers

Answer:

D - How trichoplax adhaerens eats by engulfing it's food

Phagocytosis is a process in which Trichoplax adhaerens eats by engulfing its food, which is in Option D. It is a process by which the cells engulf the food that is coming from the outside of the cell.

What is phagocytosis?

The cell has many organelles, such as the lysosome, vacuole, cell nucleus, etc., but each organelle has a special function, and one organelle cannot take over the function of another organelle. The lysosomes have a very unique and acidic environment that destroys the organelles, such as old organelles, and kills viruses, etc.

When outside food particles or pathogens enter the cell, they enter as a vacuole, and the cell transports them from the outside to the inside through a variety of processes. The cell then eats them, a process known as phagocytosis, and if it is a virus, the lysosome degrades it.

Hence, Phagocytosis is a process in which Trichoplax adhaerens eats by engulfing its food, which is in Option D.
