Answer:
Explanation:
The basic mechanism of translating the nucleotide code of mRNA into the amino acid sequence of a protein, as performed by the ribosome, is well conserved throughout evolution. The process of protein synthesis can be subdivided into four major steps: initiation, elongation, termination, and ribosome recycling.
Toxicology is the study of toxin effects on human health. The individuals or professionals who carry out toxicology are called toxicologists. In toxicity testing, the dose of a chemical above which there is a measurable decline in the health of the organism being tested is referred to as the toxicity threshold. After identifying the effects and the toxins in the body of an organisms toxicologists device ways of removing or neutralizing the toxin so as to avoid any damaging effects to the body tissues.
Answer:
. Experimentation is the heart of science. Scientists ask questions, gather evidence, share ideas, and analyze data. In designing an experiment, the specific question (or questions) that the experiment is meant to answer must first be clearly identified.
Explanation:
Answer:
It lacks a nuclear membrane and resides inside the nucleus.
Explanation:
The nucleus is considered as controlling centre of the cell. The parts of the nucleus includes nucleolus, nuclear pore, chromatin, and nuclear envelope. Nucleolus is the part of the nucleus which is present inside the cell and lacks a nuclear membrane and its function is producing and assembling of ribosomes.
The reason for not considering other statement as true are as follows:
1. Nucleolus is found only in Eukaryotas.
2. Nucleus is the control centre of the cell.
3. It lacks a nuclear membrane and resides inside the nucleus.
Answer:
takes substances captured from the external environment (air and carbon sources) and converts them into energy for building more cells and tissues and for carrying out life-sustaining activities. It also generates waste products and water.
