It's need to pass oxygen to the blood to the respiratory system work properly I think that the answer
Answer: change from one form of energy to another
Explanation:
As the name implies, Energy transformation refers to the conversion of one form of energy to another, such that energy is always conserved.
For instance:
- an electric pressing iron convert electrical energy to heat energy;
- a solar panel convert solar energy to electrical energy etc
All these are examples of energy transformation in nature.
Answer:
they can insert the codon that encodes phenylalanine by CRISPR-Cas mediated homology-directed repair
Explanation:
The CRISPR (clustered regularly interspaced short palindromic repeats,)-Cas (CRISPR-associated protein) is a versatile technology for genome editing which has been developed by adapting a natural defense mechanism found in prokaryotic organisms. The CRISPR-Cas genome editing tool can be used to edit DNA sequences in eukaryotic genomes (for example, in human genomes) and thus restore gene function (in this case, the CFTR gene function). The system consists of a Cas protein that cleaves the DNA at specific genomic sites and a single guide RNA (sgRNA) that guides the Cas protein at specific genomic locations. CRISPR-Cas mediated homology-directed repair refers to the process where Cas cuts the DNA to triggers the homologous recombination (HR) DNA repair pathway, by which it is possible to insert new genetic sequences at specific genomic sites (in this case, the codon that encodes phenylalanine within the specific CFTR gene).
<span>The question is asking us the following: "In the food chain below, which is the producer?
And the food chain is: flower - mouse - snake- hawk", The producer is the organism that can produce energy from the source, typically from the sunlight, without eating parts of other animals. Producers are plants - and almost all plants are produces (some are also consumers). so the answer is "flower'</span>

a bacterium is spherical in shape
