Answer

B. Compound microscopes

Explanation:

Compound microscopes are light illuminated. The image seen with this type of microscope is two dimensional. This microscope is the most commonly used. You can view individual cells, even living ones.

Greenhouse gases are measured by their ability to trap outgoing solar radiation and convert it to heat, warming the atmosphere.
Gnom [1K]

Answer:

Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.

Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.

This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.

Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.

Ivenika [448]

Answer: The attachment listed some cell organelles,although there isn't a specific question on then but am going to be defining each of them and state their functions as well.

1. The Nucleus; The is command centre of the cell, it is made up of nuleolus, chromosomes, nucleoplasm,nuclear envelope and nuclear lamina.

it contains the genetic/hereditary materials that the cell is made up of.

The Nucleus plays a great role in the control of growth and development of the cell.

The nucleus also coordinates some of the the activities of the cell like cell division and protein synthesis.

2. Cytoplasm; The cytoplasm is one of the cell organelles,it is the liquid portion of the cell,it consists of cell contents between the plasma and the cell membrane. The fluid cytoplasmic material is where many cell organelles are found/suspended fluid. Most activities carried out by the cell occurs in the cytoplasm.

3. Endoplasmic Reticulum; The Endoplasmic Reticulum is one of the cell organelles that have the structure of a network of flattened sacs and tubules and play a crucial role in plant and animal cell. Rough endoplasmic reticulum has ribosomes attached to the cytoplasmic side of the membrane and the smooth endoplasmic reticulum lacks attached ribosomes in them thus giving it the smooth appearance.

The Endoplasmic Reticulum functions in the production, processing, and transport of proteins and in and out of the cell and also the production of lipids.

4. Golgi Body; One of the plant organelles that plays a role in the sorting and organizing the proteins produced and processed by the Endoplasmic Reticulum. these proteins are sorted and packed in vessicles to be used by the body.

5. Mitochondria; (a double membrane organelle). It is otherwise known as the powerhouse of the cell,it produce/generate energy in the form of ATP needed for cellular respiration. These energy produced is used for other cellular metabolic activities.

6. Lysosome (Animal) Chloroplast (Plant); Lysosomes are found in most animal cells, they function by digesting good and garbage,they contains acids that aids this function in the stomach of the cell and when the lysosome is diseased or explodes,the cell stops functioning.

The Chloroplast on the other hand is found in the cells of plants and algae,they play a crucial broke in photosynthesis by capturing the energy from the sun and turning the captured energy into usable forms like sugar,glucose and other organic molecules.

7. Cell Membrane; The cell membrane is the cell organelle that forms a boundary between the cell and the sorounding environment.

The cell membrane as well controls the movement of cellular materials in and out of the cell.

8. Nucleolus; The nucleolus is one of the cell organelles where ribosomes are made. The ribosomes are small grain-shaped organelles that make protein and they are found in the surface of rough Endoplasmic Reticulum. Nucleolus are small and round in structure and are found in the nucleus,

9. Vacoule (Plant Cells) Centrioles (Animal Cells); The vacoule is a storage chamber(reservoir) for wanted and unwanted materials in the cell, the vacoule is found within the cytoplasm and it is enclosed by a membrane that typically contains fluid.

The centrioles on the part of the animal cell is a cell organelle that has a structure of a two hollow cylinders,ring of microtubules next to each other(the centrosome).the centrioles are located just outside the nucleus of the cell.

Centrioles function by producing the mitotic spindles for cell division, and also assisting to pull chromosome pairs apart to opposite end of the cell during cell division.

10. Cell Wall; A protective semi permeable rigid outer layer of nonliving material that surrounds the cells of plants and some other organisms.

The cell wall houses the organelles of the plant cell.

The cell wall functions by giving the cell strength and structure,it's semi permeable nature filters and selectively allows certain materials in and out of the cell.

Which approach to ecological investigations is illustrated by Biosphere 2? Defend your classification.
valentina_108 [34]

Answer:

The correct answer is : Biosphere 2 is a model based on the creation of a miniature ecosystem with life support systems.

Explanation:

Biosphere 2 is a small model of the biosphere, which is planned by scientists and engineers, that is closed and isolated from the outside world. In this study or research, the strategy for modeling is utilized to show the performance and conduct or behavior of a real biosphere.

Researchers made a model or an artificial situation that can uphold living things. It has a scaled-down model of a tropical forest, a grassland, a sea with a coral reef, a desert, and a mangrove biosphere. In these conditions, a wide range of animal varieties was contained. Furthermore, a group of eight individuals additionally fixed themselves inside it.
