Answer:
Vestigial organs show traits that a species once needed to have to perform certain tasks
Explanation:
B. Vestigial organs provide evidence for the theory of evolution:
"Vestigial organs show traits that a species once needed to have to perform certain tasks."
What do you mean by vestigial organs?
"Vestigial organs are the organs that have no apparent function and are considered to be the residual parts from the past ancestors."
What is theory of evolution?
"Theory of evolution is a scientific theory of the origin of species of plants and animals."
What do you mean by species?
"A species is often defined as a group of organisms that can reproduce naturally with one another and create fertile offspring."
What is a trait?
"A trait, as related to genetics, is a specific characteristic of an individual."
How are vestigial organs related to theory of evolution?
"Vestigial organs are often homologous to organs that are functioning normally in other species. Therefore, vestigial organs can be considered evidence for evolution, the process by which beneficial heritable traits arise in populations over an extended period of time."

How many years ago is .3 million years?
How about .02 million years?
Answer:
300 000 Years is .3 years
200 000 Years is .2 years
(hope this helped if ya need more dm me on discord AkashTheMissle07#3880)
Explanation:
0.3 year ago is three hundred thousand year ago and 0.2 year ago is two hundred thousand year ago.
What is year?Every planetary body has an orbital period, it is called as a year. when earth complete its one orbit around sun, we call it a year. Due to earth's axis, we experience seasonal changes throughout a year.
The earths rotation period is approximated into number as calendar. The modern calendar is called as Gregorian calendar represents 365 days of year, or 366 days of a leap year.
To denote period, loosely associated with it, year is used. Most civilized types of calendar used are Gregorian calendar, it uses two notions, to indicate numbering of year, AD is short form of "Anno Domini" (meaning "in the year of the Lord"), and CE is short form of "Common Era".
So basically 0.1 million year refers to 1000 000 year ago, therefore 0.3 year is 3000 000 and 0.2 is 2000 000 years.

Why are cells, tissues, organs, and organ systems all important for a living body?
Answer: Because each one of them helps other organs, cells, etc.. Because everything in your body needs to work together. For example, one of the most important functions of organ systems is to provide cells with oxygen and nutrients and to remove toxic waste products such as carbon dioxide.
Transcription is A. The process of making RNA from DNA. B. The activation of a gene that produces proteins. C. Irreversible changes to the DNA sequence. D. The process of making proteins from RNA
Answer: A. The process of making RNA from DNA.
Explanation:
The transcription can be defined as the process of transfer of genetic information from DNA or deoxyribonucleic acid into messenger RNA. For this double strands of DNA are separated and each strand act as a template strand for the synthesis of mRNA. The transcriptions is initiated by the enzyme RNA polymerase. The enzyme RNA polymerase utilizes DNA for synthesizing the matching complementary bases. The mRNA molecule get elongated and serves as a blueprint for the synthesis of protein in translation.
The imaginary line running through the center of Earth from the North Pole to the South Pole is called the _____________ .
A) orbit
B) revolution
C) axis

What happens to a CO2 molecule when an infrared wave hits it?
The energy from the photon causes the CO2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon. Once the extra energy has been removed by the emitted photon, the carbon dioxide molecule stops vibrating.

Which student identified the correct step and the result of that process?
Frank claims step 1 is DNA replication which produces proteins needed by the organism to grow and develop
Emma claims step 2 is transcription, resulting in a double stranded RNA molecule needed for translation in the nucleus
Francine claims step 3 is translation which produces the mRNA strand by reading and pairing bases to the DNA template
Tyrone claims step 4 is the production of amino acids, which will form proteins, resulting in the expression of genes found in DNA
Answer: Emma claims step 2 is transcription, resulting in a double stranded RNA molecule needed for translation in the nucleus

what causes biodiversity?
Answer:
temperature, altitude, precipitation, soils, and their relation with other species.
Answer:Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.The various factors that influence biodiversity include -temperature, altitude, precipitation, soils, and their relation with other species. For instance, ocean biodiversity is 25 times lesser than terrestrial diversity. Biodiversity also increases its form as it moves from the poles towards the tropics.
