Think about a petal plucked from its flower. Is the petal alive according to the characteristics of life? Why or why not?

Ray Of Light [21]

No, that is because a living thing would need to reproduce, and also include living cells. When you remove the pedals, it will rot after a bit and then eventually die completely.

Cacti in the deserts of southwestern North America and some euphorbs (succulent plants) of the deserts of Africa, have barrel-sh

mylen [45]

Answer:D. convergent evolution

Explanation:

Cacti or cactuses are member of the plant family and are often referred to as spiny plants that are usually found in the desserts.

Evolution - In biology, is described the ascent or descent in the characteristics of a species over a series of generations

and natural selection favors its modification.

When two species populations evolve to become more similar to each other we say say they have a convergence evolution.

Hint: Evolution of analogous structures is always an example of convergent evolution.

DNA Replication Assignment

dem82 [27]

Answer:

This question is asking to do the following:

Replicate the DNA sequence

Transcribe the complementary DNA into mRNA

Translate the mRNA codons into amino acid sequence

Give the function of mRNA

Please find the detailed answer to this question below

Explanation:

- DNA replication is a process whereby the content of DNA (genetic material) is doubled i.e. duplicated. In other words, another copy of DNA is made from one a DNA template. The principle of DNA replication follows the complementary base pairing rule i.e. A-T, G-C

Original DNA template- A T G G G T C T A G C G A A A G A T

After DNA replication-

Complementary DNA strand- T A C C C A G A T C G C T T T C T A

- Transcription is the process whereby a DNA template used to synthesize a mRNA strand. In this case, the complementary DNA sequence above will be transcribed into a complementary mRNA sequence. Note that Uracil replaces Thymine in RNA.

Complementary DNA strand- T A C C C A G A T C G C T T T C T A

After transcription

mRNA strand- A U G G G U C U A G C G A A A G A U

- Translation is the process by which a amino acid sequence is synthesized from a mRNA sequence. The sequence of the mRNA is read in a group of three bases called CODON. Each codon specifies an amino acid. In this case; the mRNA sequence is A U G G G U C U A G C G A A A G A U

After translation using the genetic code, the amino acid sequence is:

Methionine- Glycine- Leucine- Alanine- Lysine- Aspartic acid

Note:

AUG codes for Methionine (Met)

GGU codes for Glycine (Gly)

CUA codes for Leucine (Leu)

GCG codes for Alanine (Ala)

AAA codes for Lysine (Lys)

GAU codes for Aspartic acid (Asp)

- mRNA, which means messenger RNA, is a type of RNA molecule whose major function is to transport genetic information out of the nucleus into the cytosol in order for translation to take place. In contrast to DNA, which is a storage molecule, mRNA is a transporting/carrier molecule that encodes genetic information.

Which part of a light compound microscope would be most useful in adjusting the amount of light on a specimen? A) diaphragm B) e

Musya8 [376]

Answer:

A) diaphragm

Explanation:

A compound microscope is used for viewing small objects as it magnifies the image and makes it easy to observe them.
The diaphragm is a part of the compound microscope which is used for adjusting the amount of light so that one can view the specimen in a suitable manner.
The light source is located just under the stage where the slide is placed and the rotation of the diaphragm allows to adjust the intensity of the light illuminating the specimen.

WILL GIVE BRAINILIST

Andreyy89

Answer: A). cause the three bones of the middle ear to begin to vibrate.

Explanation: Sound is transmitted as waves from the outer ear through the ear canal to the ear drum. The sound waves causes the eardrum to vibrate and consequent vibration of the three tiny bones of the middle ear. The vibration of the three tiny bones causes the fluid in the inner ear to vibrate. The vibration of the fluid causes the tiny hairs to vibrate and and the vibration is converted to electrical impulses that are transmitted to the auditory nerve and to the brain, where they are intepreted as hearing (sound).
