False. Composting is not a modern process invented in the 1940s.
The statement is false. Composting is not a modern process invented in the 1940s. In fact, composting is an ancient practice that has been used for thousands of years. It dates back to ancient civilizations, where organic waste materials were intentionally decomposed to create nutrient-rich soil amendments.
Composting is a natural process of decomposition in which organic materials, such as food scraps, yard waste, and other plant-based materials, are broken down by microorganisms and turned into compost. This process is facilitated by various factors, including moisture, oxygen, and the presence of beneficial bacteria, fungi, and other organisms. Composting helps to recycle organic waste and transform it into a valuable product that can be used as a fertilizer and soil conditioner.
While the understanding and scientific knowledge of composting have certainly evolved over time, the basic principles and practice of composting have been utilized by civilizations throughout history. Therefore, composting is not a modern invention of the 1940s but a long-established method of managing organic waste and enriching soils.

Yall Im struggling, if u cant read it, the question is “why does a mountain climber need an oxygen supply at very high altitudes, even tho the air still contains 21% oxygen?
Answer: Because it is harder to draw breath in. And the cold
Explanation: At higher altitudes, it becomes more dangerous, and you can develop altitude-related illnesses such as HAPE and HACE. I read a book called Into Thin Air, and in the book the author goes into detail on the details/complications of climbing Mt.Everest and oxygen needs. Mountain climbers use canisters of oxygen called Supplemental Oxygen.

how are viroids different from viruses
Answer:
We are all familiar with the basics of viruses: These particles infect living cells and wreak havoc throughout the body. But viruses aren’t the only villains around causing chaos in living things. Other infectious agents called viroids and prions — which are also tiny but powerful — can take down both plant life and entire animals.
Viroids are free RNA molecules of low molecular weight without any protein coat, while viruses can have either RNA or DNA molecules encapsulated in a protein coat. Viroids are smaller in size than viruses.
Viroids not made of cells.
Viroids don’t transform energy.
Viroids can’t reproduce on their own.

1. What were the conditions on the planet when life began?
Answer: The early Earth had no ozone layer and was probably very hot. The early Earth also had no free oxygen. Without an oxygen atmosphere very few things could live on Earth. Anaerobic bacteria were probably the first living things on Earth.
Which of these contributes the most oxygen to our planet?
a. Photosynthetic fungi
b. The Amazon Rain forest
c. the National Forests
d. Phytoplankton
Answer:
D. Phytoplankton
Explanation:
The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.

Without genetic variation, natural selection would not be possible. Explain why.
Answer:
Without genetic variation, natural selection is only able to grow the number of allelomorphs that previously exited in the population. Natural selection occurs through an interaction between the environment and the variability of the individual organisms making up a population. If every giraffe had the same neck length, there would be nothing to change and they would never have a long neck by now.
What is the structure of a virus?
Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
A virion consists of a nucleic acid core, an outer protein coating or capsid, and sometimes an outer envelope made of protein and phospholipid membranes derived from the host cell. The capsid is made up of protein subunits called capsomeres. Viruses may also contain additional proteins, such as enzymes

What is EPA?The Environmental Protection Agency (EPA) is a federal agency of the United States government that was established in 1970 to protect human health and the environment. The EPA's mission is to ensure that all Americans have clean air to breathe, clean water to drink, and safe land to live and work on. The agency is responsible for setting and enforcing national standards for air and water quality, as well as for managing toxic waste and other pollutants.
The EPA also works with other federal agencies, states, tribes, and local governments to address environmental challenges, such as climate change, ozone depletion, and exposure to hazardous substances. The EPA uses a range of tools and programs, including research and development, regulation, partnerships, and education and outreach, to achieve its mission. The agency also provides information and technical assistance to help individuals, communities, and businesses protect the environment and public health.
