Answer:
The Malthusian Theory of Population: The concept that the human population exponentially grows and will eventually be too large to be supported by the food production rate, leading to mass starvation.
People who believe this are Malthusians.
Explanation:
This is more of an APHG question, but yeehaw
Answer:
A group of bacteria that accumulate in layers and secrete an protective extracellular material.
Explanation:
The biofilm is a natural way how the bacteria get together to survive in an ecosystem or in another living thing. They build little by little this kind of building with different layers of bacteria that secrets a polymer, this protection polymer could be useful to protect the colony or to be attach to another cell or to a tissue. In medicine and in veterinarian studies is interesting because can be useful to create a film to protect some injuries.
Answer:
can adapt to environment, access to food, ability to mate and reproduce
Explanation:
yea this should be right
Answer:
The correct answer will be option-A and B.
Explanation:
Transcription is a process which synthesizes a complementary molecule of DNA which acts a messenger called RNA.
The gene contains a sequence of the nucleotide at the beginning of gene called promoter sequence. The promoter sequence has the ability to attach an RNA synthesizing enzyme called RNA polymerase.
The RNA polymerase is the enzyme which synthesizes the RNA molecules using a single strand of DNA called template strand. RNA polymerase binds nucleotide at 3' end of the strand thus proceeding the strand in 5' to 3' direction.
The promoter and RNA polymerase begins the process of transcription and thus option-A and B is the correct answer.
PP- purple homozygote
pp- white homozygote
Pp- purple hetrozygote
If these flowers cross, we obtain heterozygote offsprings with a genotype: Pp (100% of them will be like this)
Now, if those offsprings cross with each other: Pp x Pp
results:
1/4 would be purple homozygote -> PP
1/4 would be white -> pp
2/4 would be purple heterozygotes -> Pp
Genotipic ratio: 3:1 (3 are purple; 1 is white)
