Answer:
Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. ...

Answer: check explanation.
Explanation:
Transcription is a process in which protein is being produced or synthesized. Transcription can also be defined as the transfer of genetic instructions in DNA to RNA. Transcription uses the DNA in the nucleus to make an RNA molecule. Then, the RNA will now leave the nucleus for ribosome(cytoplasm).
Transcription takes place in three steps and they are;
(1). INITIATION STEP: in this step, the RNA polymerase(an enzyme) binds to the promoter.
(2). ELONGATION STEP: in this step, we have the addition of nucleotides to the mRNA strand.
(3). TERMINATION STEP: In this step, we have the RNA polymerase crosses a terminating sequence in the gene. Here, the mRNA strand detaches itself from the DNA.
After the three steps above, we have the processing of the mRNA. This additional processing include, Splicing(removal of introns from mRNA), Editing( changes in nucleotides in mRNA) and Polyadenylation(addition of tail).
The parts of the experiments that would be used to check temperature to know if this antibiotic works are:
- The independent variable is the new antibiotic,
- The dependent variable is the temperature of the cattle.
- Controlled variable is the quantity of antibiotics they are to receive.
- The control group is the group of cattle i own that are not being treated with antibiotics.
- The experimental group is the cattle that are receiving the antibiotics.
The independent variable is the new antibiotic that is going to be used to treat this fever in the cattle.
The dependent variable is the temperature of the cattle. The temperature of the cattle depends on the effectiveness of the antibiotic
The controlled variable is the quantity of antibiotic that the cattle is to receive.
The control group are those cattle that I own that will not be receiving this drug.
The experimental group are the group of cattle that are going to take the antibiotics.

NUCLEUS IS CALLED CONTROL CENTRE OF THE CELL BECAUSE IT PERFORMS TWO MAIN PRINCIPAL FUNCTIONS:
1. Contains genetic information for structure, reproduction , development, metabolism and behaviour. ...
2 Controls cellular activities through directing synthesis of particular proteins and enzymes.
Explanation:
It contains the genetic instructions for every function of the cell. It is the cell's powerhouse and processes energy for the cell. It is responsible for packaging proteins for delivery out of the cells.
