Two ways that bacteria cause disease are

Final answer:

Freshwater ecosystems, constituting a mere 1.8 percent of Earth's surface, are characterized by their biodiversity and the crucial ecosystem services they offer, including provision of drinking water, sanitation, and industrial uses. They house different zones due to varying abiotic factors like temperature and light penetration, with each zone inhabited by species adapted to these conditions. They are intrinsic to the well-being of terrestrial biomes, linked through various abiotic and biotic factors.

Explanation:

Freshwater ecosystems are of immense importance due to their rarity, diversity, and functionality. They encompass only 1.8 percent of the Earth's surface, including lakes, rivers, streams, and springs. These ecosystems are incredibly biodiverse, supporting a wide variety of species such as fish, amphibians, reptiles, insects, phytoplankton, fungi, and bacteria.

Humans are heavily reliant on these freshwater biomes as they provide indispensable ecosystem services. They supply fresh drinking water, assist in crop irrigation, provide sanitation facilities, recreation spaces, and serve various industrial purposes. Conservation of these freshwater ecosystems is crucial for the preservation of terrestrial biomes, as they are interlinked through abiotic and biotic factors.

Temperature, light penetration, and water movements are key abiotic factors influencing these ecosystems. The structural compositions of aquatic systems are largely shaped by density and temperature. Such factors delineate different zones within these systems, each housing organisms adapted to specific conditions.

Answer:

High blood pressure is a condition in which blood makes pressure on artery walls. It usually has no obvious symptoms, unless it is very high, and the only way to find out if high blood pressure is present is to measure it.

Arteriosclerosis is a condition in which blood vessels become thin and stiff. Atherosclerosis is a condition in which cholesterol, fats, and other substances build plaque inside the arteries. In both cases, blood flow is affected.

Glycogen provides long-term energy storage.

Glycogen is an example of a carbohydrate which is a polysaccharide that acts as a long-term energy storage compound in animals.

Further Explanation

• Living organisms require energy in order to undertake their daily activities such as growth and development, locomotion, gaseous exchange, etc. To do so they obtain nutrients for short-term and long-term energy source.
• Carbohydrates are the major energy source for living organisms, however, living organisms may use other sources of energy such as proteins or fats when carbohydrates is out of stock or not available.  

Energy source in animals

• Animals use simple carbohydrates such as glucose obtained from diet for short-term energy sources.
• These simple carbohydrates may also be stored for future use in the form of glycogen, which makes glycogen a long-term energy source, to be used when need arises.
• When glucose levels are low in the body hormones in the body trigger the breakdown of glycogen to glucose.
• Other sources of energy such as proteins and fats are used when carbohydrates storage is depleted, for example during starvation.

Energy source in plants

• In plants, on the other hand, simple carbohydrates are similarly used as a short term source of energy. Additionally, simple molecules such as glucose are stored in the form of starch for long-term source of energy for the plants.  

Why other Choices are incorrect:

Glucagon  

• Glucagon is the hormone that increases the blood glucose level to avoid it from dropping below optimum level.
• The hormone acts on the liver to stimulate the breakdown of glycogen to glucose, a process called glycogenolysis, and the glucose is released to the blood stream.

Glucose

• Glucose is a simple carbohydrate classified as monosaccharides. It acts as the short term source of energy in both plants and animals.
• It is readily broken down during the process of cellular respiration to yield energy in the form of ATP, which is then used to drive cellular processes.

Cellulose

• Cellulose is an example of a complex carbohydrates known as polysaccharides.
• It is found in plants cells lining the cell wall of all plant cells which is one of the key distinguishing feature between plant cells and animal cells.

Glycogen serves as a long-term energy storage molecule in animals, including humans. Therefore option A is correct.

It is a complex carbohydrate made up of glucose units linked together in a branched structure. When dietary glucose levels are high, excess glucose is converted into glycogen and stored primarily in the liver and muscles.

This stored glycogen can be broken down into glucose when energy is needed during periods of fasting, exercise, or other metabolic demands.

Glucose, on the other hand, is a simple sugar that serves as an immediate energy source, while glucagon is a hormone involved in regulating blood glucose levels. Cellulose, a structural polysaccharide, is not used for energy storage in animals.

Archaea and Eukarya.

On the basis of the information provided in the question, the ultimate branch of the phylogenetic tree starts with the line of Eukarya and then possesses the species of the Archaea division that comprises those prokaryotic species, which thrives in extremely tough environmental scenarios.  

As the last branch possesses species of two domains, that is, Eukarya and Archaea and it starts with Eukarya and afterward holds the species of Archaea, which shows that both Eukarya and Archaea are associated genetically.
