wind erosion can be reduced by ___.
panting trees
removing dead leaves
reducing irritation
destroying windbreaks

Answers

Answer is - planting trees!

Answer:

Planting trees

Explanation:

Wind erosion is a kind of erosion that removes the nutient-containing topsoil by the power of the wind. Wind erosion leads to the loss of nutrients from the topsoil, hence, resulting in an infertile soil for plants' growth.

Planting of trees, also known as afforestation, is one way to prevent the negative impact of wind erosion on the soil as plants helps to hold the less compact soil in place using their root systems. The shoot part of the plants involving the leaves and stem also helps to reduce the effect of the wind force. Trees are used as wind breaks for areas that are highly affected by wind.

Forests and meadows are often cut down to make way for farms or large numbers of new homes. What are some of the elements of ecosystems that are lost when plants in these areas are removed?

Answers

Answer:

When the forests and meadows are cut for making the farms or large number of homes then the area must be home for some animals.

The animals that first used to live there because of forest or large number of trees was already there.

There can be biodiversity loss as there can be beneficial plant and animal species living at that place.

So, when that place will be cleaned the biodiversity at that place will be lost.

Final answer:

Forests and meadows provide important elements for ecosystems, including plant biodiversity, water regulation, and carbon storage. Cutting down these areas can disrupt these functions and have cascading effects on other organisms.

Explanation:

When forests and meadows are cut down to make way for farms or homes, several elements of ecosystems are lost. One of the main elements is plant biodiversity. Forests and meadows are home to a wide variety of plant species, and their removal reduces the overall diversity of plants in the area. This loss of plant biodiversity can have cascading effects on other organisms that rely on those plants for food and shelter.



Additionally, the removal of plants can disrupt the water cycle. Forests, in particular, play a crucial role in regulating the flow of water. They absorb rainwater, store it in their roots and soil, and release it slowly over time. When forests are cut down, this natural water regulation process is disrupted, leading to increased runoff and the potential for erosion and flooding.



Finally, the removal of plants can also impact the carbon cycle. Plants absorb carbon dioxide from the atmosphere during photosynthesis and store it in their biomass. When plants are removed through deforestation, this carbon is released back into the atmosphere, contributing to greenhouse gas emissions and climate change.

Answers

The appropriate response is biochemistry. Eduard Buchner showed that aging can be achieved utilizing dead chemicals as opposed to living yeast. He built up that biochemical responses are conceivable outside living cells. He was awarded a Nobel Prize in the year 1907 for his discovery on fermentation. 

Eduard Buchner's and James Sumner's groundbreaking work with enzymes led to the establishment and rapid growth of the field of biochemistry, paving the way for numerous scientific breakthroughs in molecular biology, genetics, and medicine.

The work of Eduard Buchner and the discovery of enzymes laid the foundations for the field of biochemistry. Buchner's pioneering work showed that fermentation could occur outside living cells, which led to the realization that enzymes, the proteins acting as catalysts for biochemical reactions, could function independently in a living organism. In 1926, James Sumner's crystallization of urease marked the first time an enzyme was isolated, providing direct evidence that enzymes were indeed proteins. This discovery was initially met with skepticism but eventually led to Sumner receiving the Nobel Prize in Chemistry in 1946.

The enormous strides in biochemistry following these findings include the identification of thousands of enzymes and their substrates, tracing hundreds of metabolic pathways, and determining the structure of a myriad of proteins. Most notably, after the structure of DNA was elucidated in 1953, an explosion of knowledge concerning genetics and molecular biology ensued, including advancements like cloned animals, gene therapy, and enzyme immobilization for treating metabolic disorders. Biochemistry now intersects with fields such as medicine, informing the development of pharmaceutical drugs and providing diagnostic tools for diseases.

The tiles below depict translation events during roughly two cycles of elongation. each cycle adds a leucine (leu) amino acid to the polypeptide. arrange the steps into their correct sequence. place the first step at the far left. do not overlap any tiles.

Answers

I found the attached image on the internet and I believe it has the tiles referred to on the question.
As we can see on the image, the A-site, P-site, and E-site are represented. The A-site is occupied by the tRNA linked to the growing peptide chain. The P-site is the one occupied by the tRNA that works accepting the growing protein for peptide bond formation.
Firstly, the protein is formed, it is the first tile from the left.
Then, the first tile from the right is where the Leu is formed.
On the second tile from the right the Leu is then added to the protein.
The process is then repeated again as there are two cycles of elongation adding a Leu in each of them: third tile from the right, third tile from the left, second tile from the left.

The sequence is: tRNA binds mRNA, peptide bond forms, ribosome translocates.

Initiation: The process begins with the small ribosomal subunit binding to the mRNA at the start codon (AUG), marking the initiation of translation. The initiator tRNA, carrying methionine (Met), also binds to the start codon.

Peptide bond formation (Cycle 1): The ribosome moves along the mRNA, and a tRNA carrying leucine (Leu) binds to the mRNA codon complementary to it.

A peptide bond forms between the methionine and leucine, connecting the two amino acids.

Translocation (Cycle 1): The ribosome advances along the mRNA by one codon, moving the tRNAs to the next binding sites: the P site (peptidyl site) and the A site (aminoacyl site).

The spent tRNA exits the ribosome from the E site (exit site).

Peptide bond formation (Cycle 2): Another tRNA carrying leucine (Leu) binds to the mRNA codon at the A site.

A peptide bond forms between the existing leucine and the newly arrived leucine.

Translocation (Cycle 2): The ribosome moves one codon forward again, shifting the tRNAs to the appropriate sites.

The tRNA that was in the P site moves to the E site and exits the ribosome, while the tRNA with the dipeptide moves to the P site.

This sequence repeats for each cycle of elongation, adding leucine amino acids and extending the polypeptide chain.

Tascha is on a medication that increases the pH of the stomach and makes it alkaline. What is the effect of this medication?

Answers

These medicines are called antisecretory because they work by blocking the acid secretion of the stomach.

This is the case of the H2 antihistamine (such as Cimetidine) which has a rapid action (approximately 1 hour) but longer than an antacid.

When symptoms are frequent, occurring more than once a week, proton pump inhibitors (PPIs) (such as Omeprazole), antisecretory agents of potent and prolonged action (at least 24 hours), constitute the treatment of choice.

Explanation:

A medication that increases the pH of the stomach and makes it alkaline is actually helping in neutralizing the acid forming in the stomach.

When there is excess of acid into the stomach then intake of a base helps in balancing the excess of acid by providing suitable amount of hydroxide ions.

Thus, we can conclude that this medication will have a neutralizing effect.

Movement of vesicles within the cell depends on what cellular structures

Answers

Final answer:

The movement of vesicles within the cell depends on motor proteins, microtubules, microfilaments, and the cytoskeleton.

Explanation:

The movement of vesicles within the cell depends on various cellular structures. One of the key structures involved in vesicle transport is the microtubules. Microtubules act as tracks for motor proteins, such as dynein and kinesin, which use ATP to transport vesicles along the microtubules.

Another important cellular structure involved in vesicle movement is the cytoskeleton. The cytoskeleton is a collection of protein filaments within the cell that includes microfilaments and microtubules. Motor proteins interact with these filaments and facilitate the movement of vesicles.

Overall, the movement of vesicles within the cell depends on the coordination between motor proteins, microtubules, microfilaments, and the cytoskeleton.

Identify all of the different observations used to support harry hess' theory of seafloor spreading.

Answers

In the 1960s Hess proposed that the crust separates along the rifts in the mid ocean ridges and that new seafloor forms by upwelling of hot new crust into these cracks. Magnetic anomaly patterns on the sea floor provide evidence. They are peculiar banded magnetic patterns found on the sea floor. By using the age of magnetic reversals they could calculate the rate of seafloor spreading using the equation speed=distance/time. Another line of evidence is the fact that rocks closest to the spreading ridge are younger and older rocks are further away. 

Compare the effects of disruptive, directional and stabilizing selection on the genetic makeup of a population answers

Answers

Disruptive selection describes changes in population genetics in which extreme values for a trait are favored over intermediate values and it is also called as diversifying selection. In this case, the variance of the trait increases and the population is divided into two distinct groups. Directional selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype. Stabilizing selection is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value.

What is 90% of the biological stuff in soil?

Answers

it will be inorganic

The correct answer is that 90% of the biological stuff in soil is humus.

Humus is the dark, organic material in soils, formed by the decomposition of leaves and other plant material by soil microorganisms. It is a complex and stable mixture of carbon compounds that can persist in the soil for hundreds of years. Humus plays a crucial role in soil fertility and structure, improving the soil's ability to retain water and nutrients, and providing a habitat for beneficial microorganisms. It is estimated that humus can constitute up to 90% of the organic matter in soil, which is why it is often referred to as the ""lifeblood"" of fertile soil. The other options mentioned, such as bacteria, fungi, and protozoa, are also important components of soil life but do not make up the majority of the biological material in soil to the extent that humus does.
