Answer:
In evolutionary biology, abiogenesis, or informally the origin of life (OoL), is the natural process ... For the oldest life forms, see Earliest known life forms. ... There are several principles and hypotheses for how abiogenesis could have occurred. ... In 2017 scientists found possible evidence of early life on land in 3.48 Gyo
Explanation:
Many scientists favor the RNA world hypothesis, in which RNA, not DNA, was the first genetic molecule of life on Earth. Other ideas include the pre-RNA world hypothesis and the metabolism-first hypothesis. Organic compounds could have been delivered to early Earth by meteorites and other celestial objects. We can only speculate about these questions, since we haven't yet found any life forms that hail from off of Earth. But we can think in a more informed way about whether life might exist on other ... When did life appear on Earth? ... For many millions of years, early Earth was pummeled by asteroids and other celestial objects.

Ribosome This organelle is the site of polypeptide assembly. This two part organelle is found in endoplasmic reticulum.
Lysosome The cellular digestion and disposal of biological molecules occur inside this organelle. Mitochondrion Aerobic respiration occur in this organelle.
Endoplasmic reticulum This generally play role in cell defence.

Answer:
Absorption
Explanation:
Epithelial tissue aid absorbtion, secretion, and excretion of substances. In the intestines, it aid absorbtion of nutrients during digestion.
The columnar epithelium possess pillar-like and column-like cells located in the lining of the stomach and intestine. It aid absorption and secretion.
The types of animal tissues are the Connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connectuve Tissues arises from the mesoderm. All connective tissue is made up of three major components: fibers (elastic and collagenous fibers), ground substance and cells.
Basic functions of connective tissues includes binding and supporting, protecting, insulating, storing reserve fuel, and distribution of substances within the body.
Answer: Overfishing is a dangerous global issue that is often overlooked people who do not directly rely on marine wildlife for protein. However, as billions of people live near coastal areas and rely heavily on marine wildlife to sustain their lifestyles, overfishing can produce an additional burden on populations that live inland. Therefore, it is up to us, as individuals, to help prevent overfishing. By staying informed, understanding what you eat, and helping to spread the word, we can inform others to act responsibly.
