<span>The answer is the option a. Filter feeders - strain food from water. You can realize the the option b is no rirght because carnivores eat meat (other aninals), c is not rigth because paraistes do not help other animals but they harm other animals, and d. is not right because herbivores eat plants and not bits of decaying matter. So you can eliminate b, c, and d. While a. reflects exactly what filter feeders eat.</span>
I am sorry I wish I could help you. Sorry
1) What sequence of nucleotides does the guide RNA need to include, to kill the bacterium is the answer.
2). The action of the Cas-9 protein.
Explanation:
CRISPR is a genetic engineering technology used to detect and destroy DNA of the bacteriophage which have infected the bacterial cell previously.
The CRISPR are the sequences of bacteriophage DNA found in genome of the bacteria when bacteriophage has infected it before.
It alters the DNA sequences and modify the function of gene is bacteria.
Cas-9 is an endonuclease which cuts the DNA identified by or complementary to CRISPR.
This system makes bacteria anti viral.
It is an example of acquired immunity.
If no meiosis takes place chromosome number will be doubled disturbing the genetic make up of the organism.
Explanation:
If no meiosis takes place then the resulting zygote will be of double the number of chromosomes. The genetic makeup will change entirely. The process of meiosis halves the number of chromosomes in haploid cell and maintain the serenity of organism.
The process of meiosis due to crossing over, genetic variation occurs which let the offspring receive favourable alleles to survive in new conditions.
In diploid organisms first the gametes are formed, then fertilization occurs and the diploid cell is formed which gives rise to the organism having diploid cells.
