The True statements are.

Organisms in a population must compete for the resources as the resources are limited and the organism that compete and survives wins.

The best equipped organism survive which is known as the survival of the fittest.

Over the time due to challenges in the environment the beneficial variation takes place in the organisms and it spreads through the generations and then it gradually changes the whole population.

The false statement is Organism of the same species are equipped with the same survival skills.

The organism of the same species have some variation and because of this variation they compete and win against the other member of the same species.

The DNA of a certain organism has adenine as 40% of its bases. What percentage of its bases would be guanine?
Mandarinka [93]

Answer:

The correct answer is B)10%. See the explanation below, please.

Explanation:

We use the following equivalence, remembering that Adenina pairs with Timina and Guanina with Cytosine:

A=T   ; C=G   A+G=T+C

If A= 40% ----> T=40%

A+G=T+C

40%+G= 40% +C   ---->  40+10=50

G=C=10%

lys-0071 [83]

Answer:

At almost the opposite point on the Earth's surface, the "P" waves reappear. The shadow zone exists because the waves are refracted as they pass through the boundary between the mantle and the core and are diverted from their original paths.

The following sequence of double stranded DNA encodes a hypothetical protein called GEN in a bacteria. Transcription starts at a
vaieri [72.5K]

Answer:

A) AUG GAG GGU

B) N-MET-GLU-GLY-HIS

C) 10 amino acids

D) The stop codon here is UAA, instead of UAG.  If a tryptophane residue is added where the stop codon is, the GEN polypeptide would be longer

Explanation:

First we must obtain the the complementary chain or mRNA

A) AUG start codon is complementary to DNA TAC triplet, and GAG is complementary to CTC, and GGU to CCA (running from left to right towards 5'DNA direction (AAGCGGATACCTCCCAGTAGATGCTCCGGGGCTAGTGATTTCGAAC-5)

B) TAC corresponds to Methionine, GAG to Glutamate, GGU to Glycine, and CAU to Histidine

C) UAA is the stop codon, that is complementary where the DNA triplet is ATT.  From AUG to UAA, we can have 10 amino acids transcribed

D) If a trp is included where the stop codon is UAA, then the mRNA would be longer with a consequent traduction of a longer GEN polypeptide

Why does exposure to high temperatures cause an enzyme to lose its biological properties?
Ivanshal [37]

Answer:

Shape of active site changes that's why

Enzymes are affected by temperature. So, as temperature increases, enzymes activities also increases, till optimum temperature is reached. If it goes above the optimum temp, the enzymes becomes denatured or can't function anymore due to change in its active site.
