Answer:
Shadows are longest in the early morning and late afternoon/early evening when the sun appears low in the sky. As the Earth rotates on its axis, the sun hits each location in the morning at an angle. ... As Earth continues to spin toward sunset, the increasing angle causes shadows to lengthen!

Hope this helps! Have a good day!.....or not...its up to you- <3
Answer:
It's an advantage for the bacteria, not an advantage for the salamander
Explanation:
The point of reproduction ideally is to produce as many offspring in as little time as possible, to increase the number of offspring that thrive. Therefore the bacteria being able to multiply quickly is an advantage and will most likely increase the chances of evolution occuring sooner (antibiotic resistant bacteria for example). The salamander having to wait 4 years to have few offspring will make the number of babies they're able to have in a lifetime rather low.
Genome mapping is used in gene therapy and specific gene location in a genome.
Explanation:
Genetic mapping is a technique in molecular biology where the genome of an organism is sequenced ie its DNA is known.
These DNA sequences form genes, these genes are located on chromosomes along with histone proteins. T
The chromosomes are sequenced and specific gene location and size along with the number and specific nucleotide is known.
After knowing the exact location of gene on which chromosome it gets easier for research purpose and molecular markers are made to detect them in sample.
The gene therapy procedure gets sorted with knowing the exact gene and replacing the faulty ones.
Answer:
1: Thewissen and colleagues have discovered the skeleton of Indohyus, an approximately 48-million-year-old even-toed ungulate from the Kashmir region of India, as the closest known fossil relative of whales.
2: Bones protect and support vital organs and work with muscles to help the body move. To gain strength and stability, bones and teeth must absorb nutrients, such as calcium and phosphorus, in a process called mineralization.
Explanation:
sorry I dont have the answer to the 3rd question. Glad to be of help though
What animals did the grant study in galapagos island?
Galapagos finches did the grant study in Galapagos island.
Galapagos finches is a piece of evidence supporting the theory of evolution.
Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.
What did he observe?
During the survey voyage of HMS Beagle, Darwin was unaware of the significance of the birds of the Galapagos. He had learned how to preserve bird specimen while at the University of Edinbugh and and had been keen on shooting, but he had no expert in ornithology and by this stage of the voyage concentrated mainly on geology. Nonetheless, these birds were to play an important part in the inception of Darwin’s theory of evolution by natural selection.
What was the brief goal of their studies?
All of Darwin's observations and insights, plus reading of increasing population growth and demand for limited resources, brought him to his theory of natural selection. Briefly, this means that individuals better adapted to their environment survive and increase in number through reproduction.
What did they conclude?
Conclusion:
Charles Darwin deserves primary credit for the theory of evolution. He developed existing ideas about descent with modification while providing a large body of evidence in support of them, and he was the first person to perceive thatnatural selection is the primary force behind evolution.
