What are coral reefs?

A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.

Coral reefs are massive structures made of limestone deposited by coral polyps. Often referred to as the “rainforests of the sea,” coral reefs support approximately 25 percent of all known marine species.

Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.

Answers

C. They are required in large in large amounts for organisms to survive

Macronutrients are all substances that provide energy to the metabolism for optimal functioning, nitrogen and phosphorus are required in large amounts for organisms to survive.

What are macronutrients?

It refers to those elements that provide energy to the body, these are proteins, carbohydrates and lipids.

Nitrogen and phosphorus, meanwhile, allow the development of metabolic processes, prevent infections and contribute to growth.

Therefore, we can conclude that the body requires a greater amount of macronutrients than micronutrients, nitrogen and phosphorus are required in large amounts for organisms to survive.

Like other living creatures, fish must meet certain basic needs for survival. Water, food and shelter are among the most important requirements:
• Water: Fish not only live in water, but they get oxygen from water. They breathe by taking water into their mouths and forcing it out through gill passages.
• Food: Fish must be able to find enough to eat at various life stages, whether they feed on microorganisms, small fish or larger prey.
• Shelter: Fish need a place to hide from predators and to reproduce. Some fish find shelter among submerged aquatic plants and shoreline vegetation, while others hide among rocks, soft sediments, or blend into clear, open waters.

Answers

An ecosystem that can experience a disturbance without being fundamentally damaged is said to have: Inertia.

An ecosystem can be defined as a biological community or space that comprises all living organisms (biotic factors) and the physical environment (abiotic factors) with which they interact.

Basically, an ecosystem is responsible for the provision of the following essential services that are very vital and important for the sustenance of life in all living organisms;

Plant pollination.Water purification.Nutrient cycling.

Additionally, an ecosystem is said to have an inertia if it experiences a disturbance or factor of changes without it being damaged significantly or fundamentally.

For example, the development of shrub forests during the Medieval Warm Period is an inertia of the ecosystem.

B. What structures are missing from the root hair cells?

Answers

Answer:

The function of root hairs is to collect water and mineral nutrients that are present in the soil and take this solution up through the roots to the rest of the plant. As root hair cells do not carry out photosynthesis, they do not contain chloroplasts.

Explanation:

Mitochondria are missing from root hair cells.

Root hair cells are specialized plant cells found in the roots of plants. Their primary function is to absorb water and minerals from the soil. To achieve efficient absorption, root hair cells have evolved specific structural adaptations.

Root hair cells are elongated and have a large surface area due to their elongated projections called root hairs. This increased surface area enhances their ability to come into contact with the soil, maximizing water and nutrient absorption. However, due to their focus on absorption and their short lifespan, root hair cells exhibit some structural simplifications, such as the absence of certain organelles.

One notable organelle missing from root hair cells is the mitochondria. Mitochondria are the "powerhouses" of cells, responsible for generating energy in the form of ATP through cellular respiration. Since root hair cells are mainly involved in absorption rather than energy production, they have a reduced need for extensive energy generation. As a result, they don't require as many mitochondria as other cells that are highly metabolically active.

Active Transport.

Explanation:

Moving substances across a cell membrane against their concentration gradient, from an area of lower concentration to a region of greater concentration, is a process known as active transport in cells.

Thus, Active transport uses external energy—typically in the form of ATP (adenosine triphosphate)—to move materials against the concentration gradient as opposed to passive transport, which depends on the natural movement of particles.

Active transport involves the movement of materials across the cell membrane by means of specific membrane proteins called carrier proteins or pumps.

Thus, Moving substances across a cell membrane against their concentration gradient, from an area of lower concentration to a region of greater concentration, is a process known as active transport in cells.

approximately how many nucleosomes are required to organize this region of dna into the 10nm fiber structure?

Answers

Answer:

Answer is 512 nucleosomes.

Explanation:

DNA is the genetic material that is compressed and stored in the nucleus of the cell. Approximately 512 nucleosomes would be required to organize 92,672 base pairs long region.

What are nucleosomes?

Nucleosomes are the packaging units of the genetic material that comprises the DNA segments wrapped along with the histone proteins in a compacted manner. This allows the genetic material to be condensed into smaller volumes.

Given,

Genome size = 92,672 base pairs

Linker DNA = 35 bp

The total number of base pairs = number of base pairs in nucleosome core + linker DNA

= 146 + 35

= 181

The number of nucleosomes can be calculated as:

Nucleosomes = Genome size ÷ total number of base pair

= 92,672 ÷ 181

= 512

Therefore, there are 512 nucleosomes are present in the Drosophila.

Food is a substance consisting essentially of protein, carbohydrate, fat, and other nutrients used in the body of an organism to sustain growth and vital processes and to furnish energy.

The absorption and utilization of food by the body is fundamental to nutrition and is facilitated by digestion.

Plants, which convert solar energy to food by photosynthesis, are the primary food source.

Animals that feed on plants often serve as sources of food for other animals.

What is Fuel?

Fuel is a substance that is burned to provide nuclear energy, heat or power.

Materials like coal, wood, oil, or gas can provide heat when burned. Methanol, Gasoline, Diesel, Propane, Natural gas, Hydrogen are types of fuel. Nuclear energy is produced by burning plutonium.

From fuel efficiency or fuel economy, we can measure how long any vehicle could travel, which is the opposite of fuel consumption.

Fuel consumption is the amount of fuel vehicle uses to travel a particular distance.

Fuel efficiency can be measured in kilometers per liter. The efficiency with which the fuel does a conversion of energy is known as fuel efficiency.
