Why would it be useful for the SAME cell to be able to make different kinds of proteins at different times? Give an example, or make one up.
The cell is a complex system with specialized organelles and cellular machinery. The cell in an organisms have the same genetic material (DNA), but each cells only produce the proteins that they need in the moment or function that they are needed, that's because the cell have a "intelligent" intrecellular signaling and organization system. Some examples of these hability of the cells to control the production and liberation of proteins is the cell differentiation and the case of cells that have the function of producing protein hormones (insulin, glucagon, pituitary hormones, and hypothalamic hormones), it is important to the cells to have the control of which they produce because one cell have more autonomy and with only one genetic code an organism com be self-sufficient (molecular) and with internal protein variability.
What type of molecule is represented by the model below?
The molecule represented below is that of a cholesterol. Therefore, option (C) is correct answer.
What is cholesterol?Cholesterol is waxy. It's not always "bad." Cells, vitamins, and hormones require it. But too much cholesterol is bad. Cholesterol has two origins. Your liver produces all your cholesterol. Animal meals supply the rest of your cholesterol. Meat, poultry, and dairy contain cholesterol.
Cholesterol can be written as the chemical formula C27H46O. According to this interpretation, it is made up of 27 atoms of carbon, 46 atoms of hydrogen, and one atom of oxygen. The structure of cholesterol has a core sterol nucleus that is surrounded by four hydrocarbon rings. These rings are made up of hydrogen and carbon atoms arranged in a circular pattern.

2.-Natural forest fires
3.- Plagues and tree sickness
Human activities:
1.- Bad management of felling trees
2.-Proliferation of plagues increased by global warming

Fossil fuels are nonrenewable energy resources that are rich in carbon. Examplesof fossil fuels include oil, natural gas, and coal.How are oil and natural gas resources extracted?
Answer
oil and natural gas are extracted via a process called hydraulic fracking.
Conventional natural gas and oil deposits are found in permeable rocks, trapped below impermeable rock. These deposits can be extracted by drilling down through the impermeable rock into the permeable rock.
But gas and oil are also trapped in the spaces within impermeable shale rock. Therefore, because shale is impermeable, simply drilling down to it is not enough to extract these deposits. Instead the process of hydraulic fracturing, known commonly as fracking, is used. The rock has to be fractured to get the gas or oil out
Which statements accurately describe elements? Check all that apply.
Statements describing elements are :
1.) They integrate chemically to form new materials; they're "constructing blocks of matter".
2.) They can be damaged down with the aid of physical method.
3.) They can not be damaged down through chemical way.
4.) They're chemical combinations of less difficult varieties matter.
5.) They may be pure materials.
Chemical Element is a species of atoms which have a given quantity of protons of their nuclei, together with the natural substance consisting handiest of that species. in contrast to chemical substances, chemical elements can not be broken down into simpler substances by any chemical reaction.
An element is a essential object that can't be broken into smaller portions.There are about 100 elements, each with its personal form of atom.

All the four gas giants have rings and moons. Being theorized that the rings of Uranus, Neptune, and Jupiter are probebly a result of a meteor impact on their tiny inner satellites, forming rocky debris and dust that conitues to orbit the planet, while Saturn rings are made mostly of ice. however there is many theories, making difficult to be sure how those rings are formed.

which is one major difference between anaerobic and aerobic respiration?
Answer:
the anaerobic is a different form
One major difference between anaerobic and aerobic respiration is the electron acceptor. The correct option is b.
What is aerobic respiration?Aerobic respiration occurs in a cell when glucose is broken down with the help of oxygen to produce carbon dioxide, water, and the release of energy. For instance, aerobic respiration occurs in mitochondria.
Anaerobic respiration, on the other hand, is the breakdown of glucose without the use of oxygen in a cell, producing alcohol, carbon dioxide, and the release of energy. Yeasts, for instance, breathe anaerobically.
We can therefore draw the conclusion that the primary distinction between aerobic and anaerobic respiration is that the former requires oxygen while the latter does not.
Therefore, the correct option is b, electron acceptor.

Scientists investigated populations over fruit fly species that live on the Chinese mainland andon several small islands off the coast of China. The scientists identified that the geneticvariation within each islands fruit fly populations was high even though the islands were smalland surrounded by water. Which statement best explains the role of gene flow in thecharacteristics of the islands fruit flies?A. Different types of inherited mutations occurred in the fruit flies on each island.B. fruit flies from each island and from the Chinese mainland interacted and made it witheach other.C. a new species of fruit fly arrived on each island and caused changes that allowed theresident species to survive.D. fruit flies traveled to the Chinese mainland and the increased competition for resourceson each island resulted in the evolution of new species.
The correct option is A. Different types of inherited mutations occurred in the fruit flies on each island. Assuming these fruit flies did not have any interaction with flies from other islands, then their mutations were not shared among islands, making each fruit fly island population unique.
How does the income level of a worker impact their ability to recover from environmental disasters?
Disasters are more likely to cause lives and property damage in poor areas, and they frequently lead to an increase in poverty afterward. Poorer communities frequently do not fully recover from disasters; instead, they experience a new normal and a lower status after a crisis.
Why are the effects of natural catastrophes worse among the poor?Due to their frequent relocation to high-risk locations, poor people are more frequently impacted by natural disasters. First, regions that provide economic prospects, public services or direct comforts, as well as better productivity and salaries, may be more desirable than others.
Various economic losses result from calamities. Infrastructure and capital assets, including buildings, industries, schools, roads, dams, and bridges, are destroyed. Owing to the loss of life, the exodus of trained labourers, and the disruption of education due to the destruction of educational infrastructure
