Explain 3 ways of checking soil depletion​

Answers

Answer 1
You can check soil depletion by:

1. Contour ploughing

Ploughing along contours on a slope prevents soil from being washed away by rains and or by surface run-offs. Contours act like bunds. Terraces are leveled into step-like small fields with even slopes. Doing this is common in Asian countries.

2. Terrace Farming

On hilly slopes, terraces act as bunds and prevent the soil from being washed away by running water. This is practiced in Asia and the USA.

3. Strip Cropping

In this system, crops are grown by alternate strips of land in order to check the effect of the winds.

Fungus is an organism not drawn in the above food chain although it has a very important role. Describe an important role of organisms such as fungi and bacteria can you help me plz!!!

Answers

Answer:

Explanation:

Fungi and bacteria are decomposers. This means they help breakdown dead plant and animal matter.

This is kind of a baseline descripiton but i hope it helps!

Two of the most crucial creatures in an ecosystem are fungi and bacteria. They are essential for the nutrition cycle, the breakdown of organic matter, and the generation of food for other species. In order for other creatures to exploit the complex organic compounds, fungi and bacteria convert them into simpler forms.

What  is the way to the food chain ?

For instance, when dead plants and animals are broken down by fungi and bacteria, vital nutrients like nitrogen, phosphorous, and sulphur are released into the soil. Following the uptake of these nutrients by plants, food is produced that is then devoured by other species in the food chain.

Additionally, bacteria and fungi collaborate with other living things like plants in symbiotic interactions. For instance, several fungi collaborate with plant roots to provide the providing the plant with nutrients it needs in exchange for carbs.

Mycorrhizal symbiosis is the name for this kind of partnership, which is necessary for the development and well-being of plants. Since many bacteria and fungi produce chemicals that can stop the formation of dangerous infections, they also play a significant part in disease prevention.

Finally, fungus and bacteria are significant food sources for many organisms. For example, fungi like mushrooms and others feed animals like deer, birds, and other fauna.

which would a scientist most likely examine to locate gene mutations?

Answers

Answer:

Single base pair mutations can be identified by any of the following methods: Direct sequencing, which involves identifying each individual base pair, in sequence, and comparing the sequence to that of the normal gene.

DNA is the molecule which is most likely to be examined to locate gene mutations. Thus, the correct option is A.

What are Gene mutations?

Genetic mutations are the changes to the DNA sequence which happen during the process of cellular division when the cells make copies of the DNA molecules. The DNA molecule tells body how to form and function well.

Genetic mutations are the changes which could lead to genetic conditions such as cancer, or they could help the humans to better adapt to their environmental conditions over a period of time.

Mutations can be of many different types, such as substitution, deletion, insertion, and translocation of the genetic sequence.

Therefore, the correct option is A.

Answers

Answer:

Boiling water

Explanation:

Boiling water is an example of physical change as it does not cause any change in the chemical composition of water.

What are physical changes?

Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.

Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.

They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

In this observation, the termites and the fungi rely on each other in order for survival. In other words, they have a symbiotic relationship. This type of fungi helps the termites by digesting cellulose from the wood since termites are unable to digest it. In turn, the termites provide the fungi an environment where they can be cultivated.

Which statement correctly describes the offspring of asexual reproduction?

(Choice B)
B

(Choice C)
C
They contain half of the genetic information of the parent.

(Choice D)
D
They develop very slowly compared to offspring of sexual reproduction.

Answers

Answer: the answer is A “They result without the fusion of gametes”

Explanation:

The statement that correctly describes the offsprings of asexual reproduction is: they result without the fusion of gametes.

ASEXUAL REPRODUCTION:Asexual reproduction is a type of reproduction that involves a single parent organism. The single parent cell gives rise to two new daughter cells by undergoing division.

As a result, the new organisms are genetically identical to one another, hence, genetic diversity is not ensured.

On the other hand, sexual reproduction involves the fusion of gametes to produce genetically different organisms.

PLEASE HELP ME Are humans predators in their ecosystem? Explain in at least 5 sentences.

Answers

Their new study shows that humans are strange predators. Unlike other animals, we target adult prey in large numbers. That is a practice that can push populations of those prey into decline, the researchers warn. People mainly target — at least among wild mammals and fishes — prey that are old enough to reproduce.

Humans are considered to be apex predators in their ecosystems due to their ability to manipulate and dominate other species through hunting, agriculture and urbanization.

Why are human predators?

Humans are considered to be apex predators in their ecosystem due to their ability to manipulate and change their environment to suit their needs. Humans have the ability to hunt and consume a wide variety of other organisms, including other predators. Humans also have a significant impact on the environment through activities such as deforestation, pollution, and hunting.

However, humans are also capable of acting as stewards of the environment and preserving biodiversity through conservation efforts. The relationship between humans and their ecosystem is complex and multifaceted.

It allows the cell to regulate the movement of materials into and out of the cell

Explanation:

This molecule is a saturated fatty acid. The cell membrane is made up of a phosphate head and three fatty acid tails that form a lipid bilayer arrangement.

This lipid bilayer regulates the entry and exit of substances into and out of the cell. Small non-polar molecules, like oxygen and carbon dioxide, are soluble in the lipid bilayer and can easily cross the plasma membrane. Small uncharged polar molecules, like water, can pass through the membrane by osmosis. Larger molecules such as glucose, or charged molecules like ions, require active transport to be passed across the cell membrane.

What are the differences encountered in the photosynthetic-respiratory pathway of the carbon cycle, as it exists on land and in the ocean?

In a marine environment, the role of plants is performed by _______(phytoplankton, zooplankton, microorganisms) and an additional flux of carbon into the oceans is through _______(aeration, diffusion, deposition).

Answers

Answer:

phytoplankton; diffusion

Explanation:

"Phytoplankton" takes the role of the plant in the marine environment because it consists of tiny plants that contain chlorophyll–just like the terrestrial plants. This provides food to many aquatic animals in the ocean.

When it comes to carbon cycle, carbon dioxide from the atmosphere is being diffused into the ocean by dissolving it. The carbon in the ocean turns into an organic matter through the process of photosynthesis. The ocean is said to have more carbon compared to the atmosphere because many marine animals use it for survival.

As part of a soil analysis on a plot of land, a scientist wants to determine the ammonium content using gravimetric analysis with sodium tetraphenylborate, Na+B(C6H5)4. Unfortunately, the amount of potassium, which also precipitates with sodium tetraphenylborate, is nonnegligible and must be accounted for in the analysis. Assume that all potassium in the soil is present as K2CO3 and all ammonium is present as NH4Cl. A 5.025 g soil sample was dissolved to give 0.500 L of solution.
