Give correct procedure of activities carried out in an experiment to investigate soil drainage​

Biology
1 answer:
tatiyna3 years ago
5 0

Explanation:

These are 5 inverted cut bottles with different soils:

(Gravel, Sand, Loam, Clay, and Peat)

- The piece of cloth is tied at the mouth of the bottle to let out water at the same rate as the piece of cotton wool in the previous diagram.

- Soil that is very porous holds very little water and therefore allows too much water to pass through it.

- From the above, gravel has very large particles,it allows too much water to pass through it meaning it holds little water.

- Peat has more fine particles than Clay Soil, hence holds more water than Clay. It therefore allows very little water to pass through it.

How many atoms are in a 70 kg human?
topjm [15]

Answer:

7 followed by 27 zeros

Explanation:

The body of an adult man weighing 70 kg is made up of approximately 6.7 • 10 ^ 27 atoms.

The body of an adult male contains approximately 57% water, but if we look by weight, hydrogen is only 11%, while if we look at the mutual ratio of atoms in water, there are a total of 67% hydrogen atoms.

In this way, most of the weight (mass) of the human body comes from oxygen, but most of the atoms in the body are hydrogen.

Dina is a paleoclimatologist. she wants to review documents to assess climate data for her hometown. which historical documents
lana66690 [7]

Newspaper articles and farmers harvest yield record are the documents should Dina examine in order to assess this climate data.

Among atmospheric scientists is a group known as paleoclimatologists. There were 11,800 workers in this field in 2014, albeit not all of them were climatologists or paleoclimatologists, according to BLS data. With 40% of the workforce, professional, scientific, and technical services was the main employer of atmospheric scientists.

<h3>What level of education is required to work as a paleoclimatologist?</h3>

Your future work as a paleoclimatologist will involve a lot of biology, physics, and other hard sciences, thus there are lots of degree programs that mix these fields with the environment. Environmental biology and environmental chemistry are two examples of such options.

<h3>How far into the past can paleoclimatology take us?</h3>

Paleoclimatology makes extensive use of polar ice sheets and ice caps as well as mountain glaciers. Data from ice-coring efforts in the ice caps of Greenland and Antarctica date back over 800,000 years in the case of the EPICA project, or several hundred thousand years.

<h3>Why is paleoclimatology essential and what does it entail?</h3>

Our knowledge of Earth's climate depends on the science of paleoclimatology. Scientists can create models to help predict how rising carbon dioxide levels and other changes can affect the climate of Earth in the future as they become more aware of how climates have been influenced in the past.

Select the statements that accurately describe endocytosis. The cell membrane pinches off to form an extracellular vesicle joine
noname [10]

Answer: The cell membrane invaginates and pinches off, creating a vesicle within the cell.

Explanation:

Endocytosis is an active transport mechanism, for particules to be transported, the plasma membrane of the cell invaginates, forming a pocket around the target particle. The pocket then pinches off, resulting in the particle being contained in a newly created intracellular vesicle formed from the plasma membrane.
