Answer:

Leaves

Explanation:

Plants grow broad leaves to absorb sunlight. This is extremely helpful because this helps plants make food through photosynthesis. Roots don't absorb sunlight. They absorb water and nutrients from the soil and carry it up through the stems. The stems then transports the nutrients throughout the plant.

The three levels of biodiversity are genetic diversity, species diversity, and ecosystem diversity.

Genetic Diversity: Genetic diversity refers to the variety of genes within a species. It includes the different alleles and variations present in the gene pool of a population. Genetic diversity is important because it provides the raw material for adaptation and evolution. A higher genetic diversity within a species increases its ability to survive and thrive in changing environments. It also helps in disease resistance and overall population health.

Species Diversity: Species diversity refers to the variety of different species present in a particular area or ecosystem. It measures the number of different species and their relative abundance. Higher species diversity indicates a healthier ecosystem and greater ecological resilience. Each species plays a unique role in the ecosystem and contributes to its stability and functioning. Loss of species diversity can disrupt ecosystem balance and lead to negative impacts on other species and ecosystem processes.

Ecosystem Diversity: Ecosystem diversity refers to the variety of different ecosystems or habitats within a region or on a global scale. It encompasses the different types of ecosystems such as forests, grasslands, wetlands, coral reefs, and more. Each ecosystem has its own set of species, interactions, and ecological processes. Ecosystem diversity is essential for maintaining ecological functions, nutrient cycling, and providing various ecosystem services such as clean air, water, and food. It also supports the resilience and adaptability of ecosystems to environmental changes.

These three levels of biodiversity are interconnected and mutually dependent. They provide the foundation for the functioning and sustainability of our planet's ecosystems. Protecting and conserving biodiversity at all levels is crucial for the well-being of both human populations and the natural world.

Answer:

a. capillary action of liquid in plant stems

Explanation:

Vascular plants need to transport water from roots to stem and leaves. For this purpose, water molecules adhere to xylem cell walls (xylem is one of the two classes of transport tissues in higher plants). Adhesion, also known as capillary action, is a mechanism produced when water molecules cling to xylem cell walls. Thus, adhesion can be defined as a molecular mechanism caused by the attraction between molecules, in this case, between molecules of the xylem and water molecules.

Answer:

Anaerobic respiration

Explanation:

As rightly stated in this question, cells of all living organism synthesize ATP via the process of cellular respiration. Cellular respiration, however, occurs in stages starting with GLYCOLYSIS, which breaks down glucose to form PYRUVATE.

The metabolism of pyruvate in subsequent steps depends on whether the respiration process is occuring with or without oxygen. Without oxygen, pyruvate is metabolized in a process called ANAEROBIC RESPIRATION. Anaerobic respiration employs other molecules asides OXYGEN for last electron acceptor.

Answer:

D) cellular respiration.

Explanation:

Carbon Dioxide is a product of cellular respiration.

Answer:

As a metabolic heat.

Explanation:

The loss of energy from one trophic level to the next in a food chain occurs because energy is lost in the form of heat when the organisms from one trophic level are consumed by organisms from the next level. Only 10% of energy is transferred from one trophic level to another while the remaining 90% energy is lost in the form of heat energy in the ecosystem.

Answer:

The elements present in a human protein are Hydrogen, Carbon, Nitrogen, and Oxygen.

Explanation:

Answer:

Distance and displacement are the same in the 100-m sprint, therefore, velocity and speed are the same in the 100-m sprint.

Distance is 400 meters in the 400-m sprint, therefore Speed is not zero in the 400 M sprint.

Displacement is zero in the 400-m sprint, therefore, Velocity is zero in the 400-m sprint

Note: The question is missing some details which is given below;

A 100-meter sprint is a race using only the straight side of a racetrack. a 400-meter sprint is a race that makes one complete lap around a racetrack. why are velocity and speed the same for a 100-m sprint but not a 400-m sprint?

Explanation:

The speed of a body is the ratio of the distance covered and the time taken whereas the velocity of a body is the rate of change of displacement with time.

Distance measures the total length of space covered throughout the duration of motion, whereas displacement measures the change in a specified direction from a specific point.

In the 100 m race along a straight line, both distance and displacement = 100 m, therefore speed and velocity are the same. However, in the 400 m race, distance covered is 400 m, but the displacement is zero since the person returns to his/her starting point. Therefore, speed is not equal to zero, but velocity is equal to zero.

Explanation:

The separation of homologues occurs during meiosis I. The Option A.

During meiosis I, the process of cell division specifically designed for the formation of gametes, the separation of homologous chromosomes occurs. Meiosis I consists of several phases including prophase I, metaphase I, anaphase I, and telophase I.

In prophase I, homologous chromosomes pair up and exchange genetic material through a process called crossing over. During metaphase I, the pairs of homologous chromosomes align at the center of the cell. Then, in anaphase I, the homologous chromosomes separate and move toward opposite poles of the cell.

C. Bacteria to Seaweed to Fish to Seal to Polar Bear

Explanation:

Every ecosystem consists of multiple organisms. These organisms feed on each other, forming a food chain. The energy within an ecosystem flows through the food chain.

Here, we're supposed to determine which food chain is the correct one. All organisms can be divided into producers and consumers. Producers are organisms that produce their own food, while consumers feed by consuming other organisms.

The only food chain that makes sense is shown in option C. I wouldn't say that bacteria belong to it as the seaweed is an example of a producer. It doesn't consume other organisms. But, fish feed on it, then seals eat the fish, and polar bears eat the seals. This is why we can safely say that option C is the correct one, despite bacteria being present there. Any other combination wouldn't work as, for example, bacteria (A) and seals (B) can't eat polar bears and the fish can't eat seals (D).

Answer:

what is the question

Explanation:

is there supposed to be any picture ion get it

Answer:

Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy. Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules. Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean’s surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths. Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago. When these organisms died, slow geologic processes trapped their carbon and transformed it into these natural resources. Processes such as erosion release this carbon back into the atmosphere very slowly, while volcanic activity can release it very quickly. Burning fossil fuels in cars or power plants is another way this carbon can be released into the atmospheric reservoir quickly.Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising; it is already considerably greater than at any time in the last 800,000 years.  The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels. This extra carbon dioxide is lowering the ocean’s pH, through a  process called ocean acidification. Ocean acidification interferes with the ability of marine organisms (including corals, Dungeness crabs, and snails) to build their shells and skeletons.

Answer:

Explanation:

Metamorphic rocks are harder and denser than their parent rocks because they started off the same as their parent rocks but at some point were met with extreme heat and pressure. These conditions melted and compressed the parent rocks so much that it created metamorphic rock that was extremely hard and dense. This is why metamorphic rocks are usually found deep under the Earth's surface.

There are different types of rocks depending on their size, composition and location.

They are harder and denser than their parent rock because of tremendous radiation and temperature.

Therefore, metaphoric minerals are found deep inside the Earth.
