Answer:Molecules have size and different molecules are different sizes. When talking about the size of a molecule, most scientists will mention its molecular weight. That is the total weight of all of the atoms in the molecule. So water, which is made up of two hydrogen atoms (1 atomic mass unit each) and one oxygen atom (16 atomic mass units) has a molecular weight of 18 (well, 18.01528 to be exact). Glucose has a molecular weight of 180. DNA, which is very long, can have a molecular weight that is around 1010 (about the weight of one human chromosome).

Answer:

Explanation:
The ribosome, a biological component found in the cytoplasm of cells, is in charge of producing luciferase.
what is cytoplasm:
The ribosomes are responsible for producing all proteins.The cytoplasm of a cell contains ribosomes, which are cell organelles that allow mRNA and tRNA to function so that proteins can be produced.All of the components of a eukaryotic cell outside of the cell nucleus are referred to as cytoplasm in cell biology. Nucleoplasm is the name for the substance that makes up the nucleus and is enclosed within the nuclear membrane. The cytosol, a gel-like fluid, the organelles, and numerous cytoplasmic inclusions are the three primary elements of the cytoplasm. About 80% of the cytoplasm contains water, and it is typically colorless.After removing the cell organelles and particles, groundplasm—a submicroscopic ground cell material or cytoplasmic matrix—remains. The bigger organelles, including ribosomes, mitochondria, plant plastids, lipid droplets, and vacuoles, are suspended in this highly intricate, polyphasic structure known as the hyaloplasm of light microscopy.The majority of cellular functions, including several metabolic pathways, including glycolysis, and procedures like cell division, take place within the cytoplasm. The concentrated inner region is known as the endoplasm, and the cell cortex or ectoplasm is the name of the outside layer.This is so that codons can be inserted, amino acids can be formed, and all the proteins, including luciferase, can be formed. The ribosome traps the mRNA molecule and moves over it.

a. Radioactivity is very high and large amounts of uranium are found.
b. Earthquake and volcanic activity is evident c. The edges of plates break apart due to the crushing that occurs.
d. The borders are calm and free of plate movementad
Answer:
B
Explanation:
Tectonic plates are pieces of the rocky outer layer of the Earth known as the crust. These plates are constantly moving, and volcanoes and earthquakes are found at plate boundaries.
At the borders of major tectonic plates, earthquake and volcanic activity is evident. The correct option is b.
What are tectonic plates?A tectonic plate (also known as a lithospheric plate) is a huge slab of solid rock that is made up of both continental and oceanic lithosphere. Plate size can range from a few hundred kilometers to hundreds of kilometers; the Pacific and Antarctic Plates are among the largest tectonic Plates.
The majority of volcanoes and earthquakes form at the tectonic plate boundaries of the Earth. These plates are massive slabs of the Earth's crust and upper mantle that fit together like puzzle pieces.
Tectonic plates are fragments of the crust, the Earth's rocky outer layer. Volcanoes and earthquakes can be found along plate boundaries because these plates are continually shifting.
Therefore, the correct option is b. Earthquake and volcanic activity are evident.

it has one side that is positively charged and one side that is negatively charged
Answer:
D
Explanation:
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.

Are most environmental issues local problems or global problems?
How can or will this affect the way we try to solve these issues?
How are environmental issues becoming more complex?
What about the history of environmental studies can inform us about our current environmental issues? Why is it important to understand the past to help solve current and future environmental problems?
Answer:
Most environmental issues are problems on a global scale, these include but are not limited to, global warming, ozone pollution, greenhouse gases and many more issues.
This affects the way we try to solve these issues because if we dont all play a part to help change the way things are going, then they will only get worse. We have to come together as a whole.
Unlike individual efforts, different countries can cooperate and implement legislation which limitates all the countries in the globe,solving environmental issue more efficiently.

What is never found inside the lipid bilateral of a cell membrane
Answer:
Cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.
Explanation:
Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly. Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids. The passage of these molecules relies on specific transport proteins embedded in the membrane.

How might other organisms in the ecosystem be affected? What might happen to the population sizes of various types of organisms in the Everglades?
Answer:
As the Burmese python surpasses its carrying capacity in South Florida, the overpopulation of it leaves less resources for each python, and other organisms. Predators may have way too many pythons, and not be able to keep the balance, and prey might be over hunted or eaten. The population sizes may decrease due to the over-population of the pythons.
Explanation:
If there are ever too many of any ORGANISM in a ecosystem, the balance is sure to be ruined.

Someone please help ill give you brainliest!!!
Answer:
Work is the transfer of energy , Energy is the capacity for doing work , and Power is work being done in a unit of time.
There are 2 types of energy
Kinetic Energy : Energy of Motion
Potential Energy : Stored Energy
When calculating work energy and power you use WORK = W=Fd
Because energy is the capacity to do work , we measure energy and work in the same units. Power's SI unit of measurement is the Watt, representing the generation or absorption of energy at the rate of 1 Joule/sec. Power's unit of measurement in the English system is the horsepower, which is equivalent to 735.7 Watts.
