Answer:

Decomposer

Explanation: I just did it

An organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.

Decomposers are of great importance as they can maintain the ecosystem by breaking down dead organic matter and recycling nutrients back into it, later, these nutrients are passed from the environment to plants, then to animals, and then back to the environment. Decomposers include bacteria and fungi that consume dead plant and animal material, breaking down complex molecules into simpler compounds that can be used by plants to grow.

Hence, an organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.

Answer:

To test this hypothesis, geologists around the globe measured iridium concentrations at sites known to be 66 million years old. Because geologists knew that asteroid impacts cause minerals to fracture, they also measured the clay layers for shock-fractured minerals, like quartz.

Explanation:

These geologists raised this hypothesis because of the large crater that was in this place and the amount of fossils that are in the K / Pg boundary layer. Also the high levels of iridium.

In 1979 the scientists Luis Alvarez and Walter Alvarez led the discovery of a carbonate clay layer with iridium concentrations ten times higher than those expected in the Yucatan Peninsula.

This allowed them to propose a hypothesis about the mass extinction of dinosaurs caused by the collision of an asteroid in the Earth's crust because iridium is a rare element in the Earth's crust and ten times more concentration of it was found in this area.

On the other hand, this hypothesis was reinforced when in other parts of the world it was found that the boundary layer k / Pg had high concentrations of iridium.

The correct descriptions that help to define luminosity are How much energy is emitted per second, How much surface area the object has, and The amount of brightness of an object.

An object's luminosity, which is the quantity of energy it emits over a predetermined period, is a measurement of its inherent brightness. Since it simply measures the object's power output, it can be expressed in units like Watts.

A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.

The size, temperature, and distance of a star are the three variables that determine how bright it seems to us on Earth. The brilliance of a star is measured by its magnitude.

Answer:Ice has a lower density than liquid water because it has more space between molecules. Therefore, the correct answer is D.

Explanation:

When water freezes into ice, its molecules arrange themselves into a crystal lattice structure, which causes the molecules to be spaced farther apart than they are in liquid water. This means that ice has a lower density than liquid water, which is why ice floats on top of liquid water. When water freezes, the molecules lose some of their kinetic energy, causing them to lock into a more rigid structure, which takes up more space. In contrast, liquid water has more kinetic energy, which allows the molecules to move more freely and take up less space.

The pots in the first group would first see the sprouting of seeds.

The term solid sterilization refers to the process of using hot steam to kill bacteria in the soil. This is to ensure that the seeds in the soil germinate quickly.

Note, that gets may prevent seeds from germinating, instead killing them. As a result, farmers are expected to take steps to ensure that their seeds can survive, thrive and set fruit. This helps significantly improve the level of agricultural productivity.

Soil is home to so many organisms, and these organisms affect the soil in many different ways, that it is very important to find ways to improve soil productivity.

The pots in the first group are the first to check for seed germination because all the pots in the first group are sterilized and the pots in the second group are not sterilized.

Answer: Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.This energy makes carbon molecules an excellent source of fuel for all living things. During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel glucose and other sugars for building plant structures. This process forms the foundation of the fast (biological) carbon cycle.

Ms. Green's biology students were studying cellular respiration. Using baking yeast to test the rate of fermentation, student groups mixed yeast with different manipulated variables. The groups used the height of the carbon dioxide bubbles produced in a test tube to determine which variable(s) produced the highest rate of fermentation. Students hypothesized that adding lactose to a sixth test tube would produce the greatest amount of carbon dioxide.

Respiration is a process of overhauling complex organic molecules to produce energy. One type of respiration without oxygen, namely anaerobic respiration, will break down glucose to release stored energy. Anaerobic respiration occurs when the body needs energy quickly.

An example of anaerobic respiration alcohol fermentation using yeast. When approached, enzymes in yeast will analyze it with starch and sugar so that a decarboxylation process occurs when pyruvic acid from glucolysis breaks down carbon dioxide and carbonate groups to form acetaldehyde. Energy and carbon dioxide will be formed after acetyldehyth is reduced. Therefore the addition of lactose will produce the largest amount of carbon dioxide because lactose is a sugar molecule that is a food source for yeast.

The simulator is set to begin examining Nernst potentials related to sodium with these numbers due to the physiological importance of sodium ions in the body.

Sodium ions are one of the major electrolytes in the body and play a significant role in regulating various physiological processes. They are important in maintaining the body's fluid balance, muscle and nerve function, and blood pressure. The concentration gradient of sodium ions is maintained through the sodium-potassium pump, which pumps sodium ions out of the cell and potassium ions into the cell.This gradient is responsible for the resting membrane potential of cells. The Nernst equation is used to calculate the equilibrium potential of an ion. For sodium ions, the equilibrium potential is +61 mV at 37°C. Therefore, if the concentration of sodium ions is higher outside the cell than inside, sodium ions will tend to move into the cell, leading to depolarization and the initiation of an action potential. Understanding the Nernst potential related to sodium ions is crucial in understanding the mechanisms underlying nerve and muscle function.

Answer:
A universal common ancestor (UCA).

Explanation:
According to Darwin, all life on Earth evolved from a universal common ancestor; that is, the very first organism on Earth. If you pick any living plant or animal on Earth and trace its lineage back far enough, billions of years ago, you will eventually find the UCA. Every species on Earth is united to every other species through their connection with the UCA.

The UCA itself was probably a single-celled organism of some kind and died about 4.1 billion years ago. But through it, every species, be it human, dog, tree, or mushroom, shares this one ancestor with everyone else.

Species also have what's called a lowest common ancestor with each other, much more recent than the UCA. For example, the LCA between humans and chimpanzees probably lived and died around 4 million years ago.

When describing a community, a biologist would identify every component or characteristic of a biological community.

A biological community refers to a group of different populations that inhabit a particular geographical area and interact with one another. Biologists would observe different aspects of a community, including the organisms’ ecological roles, population size, distribution, and diversity. In addition, a biologist would also consider the types of relationships between different organisms in the community, including competition, predation, mutualism, and parasitism.

In terms of population size and distribution, a biologist would examine the population density of each species in a community, as well as the spatial arrangement of organisms. This information is essential in understanding how the different populations interact with each other. For instance, organisms with higher population densities may compete for limited resources, such as food and water.

In terms of ecological roles, biologists would identify the trophic structure of a community. This involves understanding the flow of energy through different levels of the food chain, including producers, consumers, and decomposers. Biologists would also observe how different species play unique ecological roles, such as pollination or seed dispersal.
