Similarities between gymnosperms and angiosperms:

1. They both come from the Kingdom "Plantae" and from the Domain "Eukarya."

2. They both have vascular system that are used for the conduction and distribution of water and nutrients to all the parts of the plant.

Differences between gymnosperms and angiosperms:

1. Gymnosperms are non-flowering plants whereas angiosperms are flowering plants.

2. Angiosperms have seeds that are enclosed within an ovary (it's usually in a fruit), whereas gymnosperms have no flowers or fruits. Gymnosperms have unenclosed seeds ("naked" seeds) on the surface of scales or leaves.

Alja [10]

Answer:

Aspects of evolution are constantly being challenged and explored in light of new evidence

Explanation:

The whole idea of evolution has to do with the fact that organisms developed into their present form from simpler life forms. According to Oxford dictionary, evolution is; ''the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.''

Evolution depends on evidence from fossil records. Evidences that support the theory of evolution continue to be amassed as science advances. Hence, aspects of evolution are constantly being challenged and explored in light of new evidence.

For this reason, the evolutionary history and development of whales is being hotly debated and there has recently been a major shift in our understanding of the processes used to detail whale evolution.

Which form of hypoxia occurs when body cells are unable to use o2 even though adequate amounts are delivered? (this type of hypo

Oksana_A [137]

Histotoxic hypoxia, which happens whenever body cells are not able to utilize oxygen while receiving sufficient amounts, is typically caused by metabolic toxins like cyanide.

What is hypoxia?

Hypoxia is a state in which there is insufficient oxygen reaching the tissues throughout the system or a specific area of the body.
Although fluctuations in arterial concentrations of oxygen are frequently associated with clinical conditions, they can also occur naturally during severe physical activity or hypoventilation training.

When does Histotoxic hypoxia occur?

When the supply of gas entering the cell is adequate, but the cells are unable to utilize the oxygen properly due to deactivated oxidative phosphorylation enzymes, histotoxic hypoxia develops. Ingestion of cyanide may result in this.
