How does the river change as the riverbed flattens out?
Answer:
If the gradient of the river's course flattens out, the river will deposit its load because it will be travelling a lot slower. When a river meets the sea a river will deposit its load because the gradient is generally reduced at sea level and the sea will absorb a lot of energy.

Layers of sediment form on top of one another. Sometimes, plants and animals that have died are preserved in these layers of
sediment, and fossils are formed. When the layers are dug up, the relative age of a fossil can be determined by comparing it to
fossils found in layers above and below it. Fossils from lower layers are older, and fossils from upper layers are younger
Which of the fossils shown below is most likely the youngest?
if the order is from left to right, then the first one would be the youngest
Explain why genetic variation is necessary for natural selection to occur. Include an explanation of how it affects individuals' likelihood of surviving and reproducing.

He popularized the art of beekeeping in ancient times.
He wrote a book noting the impact of insects on human remains.
He solved early criminal cases by timing the life cycles of insects.
He noted that flies were the first insects to find human remains.
An accomplishment which is attributed to Song Ci is that: B. he wrote a book noting the impact of insects on human remains.
Who is Song Ci?Song Ci was a Chinese from the Southern Song dynasty and he was a forensic medical scientist, physician, anthropologist, writer and judge. Also, Song Ci was born in 1186 and he's famously known as the founding father of forensic science for being the world's first forensic entomologist.
Historically, he wrote a book on how to distinguish between the causes and type of death. Thus, Song Ci was able to unravel and solve several criminal cases by determining their causes and type, especially through the study of the impact of insects on human remains.

When you performed BLAST search for a DNA sequence, which description is correct for “Identity value”?
a) Identity value is the number of matched nucleotide letters.
b) Identity value is the proportion of matched nucleotide letters among total size of the sequence.
c) Identity value is an estimated p-value from BLAST algorithm
d) Identity value is the number of unmatched nucleotide letters.
Answer:
the answer there is C and I also think it is
The option (C) is correct. Identity value is an estimated p-value from BLAST algorithm.
What is BLAST?In bioinformatics, BLAST is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences.
Moreover, BLAST is a computer algorithm that is available for use online at the National Center for Biotechnology Information (NCBI) website, as well as many other sites. BLAST can rapidly align and compare a query DNA sequence with a database of sequences, which makes it a critical tool in ongoing genomic research.
Hence, BLAST is a sequence similarity search tool, and it calculates an E-value and a bit-score to assess the quality of each match. An E-value represents the number of hits of equal or greater score expected to arise by chance.

Why are molecules clocks important to construction of cladgram
Answer:Molecular clocks are used to compare the number of mutations to determine how long ago a species separated and evolved.
Explanation: Yw.
Answer:
They compare the number of mutations to figure out when species split off and evolved.
Molecular clocks analyze the total amount of distinct nucleotides in two organisms' genomes to determine when they diverged from one another. The dates of evolutionary branch points are determined by the average pace at which a certain gene evolves. The molecular clocks compare the number of mutations to calculate how long ago species split and evolved in this way.

A saw mark in bone made by a small-toothed power saw will have:
Group of answer choices
very smooth walls with fine striae of the same orientation
uneven walls with striae in multiple directions and a breakaway spur
likely multiple large kerfs from the saw bouncing, striations are oriented chaotically
none of the above
A bone saw mark made by a small-tooth power saw will have very smooth walls with fine striations of the same orientation.
Effect of a bone cut by electric saw?This process causes minerals (mainly calcium) to be deposited in the part of the bone that is undergoing pressure. Therefore, the piezoelectric effect increases bone density. Piezoelectric surgery is a technique that uses ultrasonic vibrations to perform osteotomies.
With this information, we can conclude that a bone saw mark made by a small-tooth power saw will have very smooth walls with fine striations of the same orientation.
