PLEASE HELP IF YOU UNDERSTAND PHYLOGENETIC TREES
Answer:
The answer is N
Explanation:
This is because it is the closest relative not an ancestor to L and is extinct as it is not at the present time mark. We know it is the closest relative as they have the same ancestor and were around at a very similar time mark.

This picture below shows the fossil of three species of mosasuar, large marine reptiles that are now extinct what do similarities in these mosasaur indicate
The similarities in the fossil fuels of the given species of the mosasaur indicates a close relationship between the organisms.
The fossil records of the extinct organisms are used for studying the characteristics of their genome and it also helps to understand the similarities and differences between the different species of the same organism which have become extinct.
Several fossil records of thousands of organisms have been recovered and studied by the paleontologists till date. The study of these fossils have suggested that the organisms that have become extinct were very different from the organisms that are found to be present today.

The diagram represents part of a process that occurs in cells.
Which cellular process must occur before the one illustrated above?
Select one:
a. meiosis
b. replication
c. transcription
d. translation
Answer:
C. Transcription
Explanation:
The diagram shows translation, where mRNA is translated by a ribosome to create a specific amino acid sequence.
Transcription must occur before translation, because it is the process where mRNA is made.
In transcription, mRNA is transcribed from DNA, then it is sent out of the nucleus and into the cytoplasm.
Then, the mRNA goes to a ribosome in the cytoplasm, allowing for translation to occur.
So, the correct answer is C. Transcription

A student breeds a population of flowers with two alleles, red and white. Over time, the white allele, q, decreases in frequency. She plots the frequency of this allele found in her population in the graph below. Assuming that Hardy-Weinberg equilibrium holds, what is the frequency of heterozygotes in generation 6?
Answer:

Explanation:
PEOPLE HAVE ON BRAINLY HAVE BEEN PASSING OUT SHORT LINKS THAT CAN HACK YOUR ACCOUNT, DO NOT CLICK ON THE LINK AND REPORT THE ANSWER/COMMENT OR WHATEVER IT IS
THANK YOU!!
The frequency of heterozygous in generation 6 is 0.32.
What do you mean by Population?A population may be defined as the members of the same species living in a particular area at a given time.
It is clearly given in the graph that the frequency of recessive allele q in generation 6 is 0.2. Hence, the frequency of dominant allele P is 1-0.2 = 0.8.
The frequency of heterozygous will be 2Pq = 2 × 0.8 × 0.2 = 0.32
Therefore, the frequency of heterozygous in generation 6 is 0.32.

Some students at a middle school conducted a laboratory investigation to learn more about the physical properties of different elements. They observed four samples and recorded their observations in the table above. Based on these observations, which sample is most likely a nonmetal?
A.
Sample 1
B.
Sample 2
C.
Sample 3
D.
Sample 4
Answer:
A
Explanation:
1. The colour is non metallic.
2. properties of metal solidness is not there, because of results of hammer experiment.
3. Physical consistency is not solid.
Etc.
From the given observations for the four samples, it can be inferred that sample A is a non-metal. This is because the given properties of sample A do not match the properties of metals. So correct option is option A.
How do metals differ from non-metals?The properties of metals are different from non-metals. The properties of metals include a high melting point, high density, malleability, and ductility. The metals are shiny and are good conductors of heat and electricity. The metallic oxides are basic in nature
The non-metals have a relatively low melting point, and low density. They are not ductile or malleable as they are brittle. Non-metal has a dull appearance. They are bad or poor conductors of heat and electricity. The oxides of non-metal are acidic in nature.

A.natural selection
B.genetic variation
C.pollution
Answer: Genetic variation
Explanation: It could lead to natural selection, but natural selection isn't the cause. Many years down the road you could see a particular variation having a higher population, which is the result of natural selection/survival of the fittest via better camouflaging from predators.
