Answer:

The correct option is <em>'Using parasites for biological control of pests to increase crop yields.'</em>

Explanation:

Using The method of biological control for killing pests is better than using a chemical control. Chemical controls such as pesticides can lead to the pests developing resistant genes against the pesticides. As a result, the pesticides will no longer be useful for killing pests. Hence, killing of pest through biological controls is a better method. For example, the usage of parasites for killing a certain kind of pest. This will increase the crop yield.

Give an example of how a biome is an open system from the point of view of the biosphere, atmosphere, lithosphere, and hydrosphe
Karolina [17]

Given what we know, we can confirm that the biome is in fact an open system due to the interactions between the biosphere, atmosphere, lithosphere, and hydrosphere.

<h3>What is the biome?</h3>
  • The biome is the collection of air, soil, water, and all the organisms that reside within these ecosystems.
  • In order to describe an open system, we say that the system must have external interactions.
  • A biome is an open system because it has both internal and external interactions, such as with asteroids in space.
  • The internal interactions include the ones between the<em><u> biosphere, atmosphere, lithosphere, and hydrosphere.</u></em>
  • A prime example is the movement of water through each of the spheres.

Therefore, since each part of the biome interacts with each other as well as with external sources such as space, we can confirm that it complies with the definition of an open system.

the Effects of Branchial Chloride Cell Proliferation on Respiratory Function in the Rainbow Trout Oncorhynchus Mykiss
gavmur [86]

Thickening of gill epithelia in rainbow trout, caused by chloride cell proliferation, could lead to an impairment of oxygen uptake under moderate to severe hypoxia (Thomas et al 1988; Bindon et al., 1994; Greco et al., 1995).

<h3>What results in an increase in AMS in interstitial lung disease?</h3>

The number of alveolar macrophages (AMs) can rise in interstitial lung disease. Precursor cells from the peripheral circulation may have been drawn in, and/or there may have been local lung growth, to create this.

<h3>What connection does sarcoidosis have between lymphocytes and proliferating cells?</h3>

Additionally, a strong association between the quantities of lymphocytes and proliferative cells in sarcoidosis and fibrosis was discovered in bronchoalveolar lavage (BAL). Eosinophil counts and proliferating cell counts were positively associated in fibrosis.

<h3>How do AMS patients and healthy controls differ in terms of propagating AMS?</h3>

With a substantial association between these two indices, there was a considerable increase in proliferating AMs in all patient groups when compared to healthy controls (4.2 versus 1.4% Feulgen, and 2.1 against 0.5% Ki67).

After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react w
sammy [17]

Answer:

Explanation:

Oxygen gas and water must be present for iron to rust.

A region of the metal’s surface serves as the anode, where oxidation

occurs:

Fe(s) → Fe²⁺ (aq) + 2 e⁻

The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:

O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)

The overall redox reaction is:

2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)

The Fe²⁺ ions formed at the anode are further oxidized by oxygen:

4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)

This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.

Earths inner core:__as earth's outer crust:liquid​
Dahasolnce [82]

Answer:

The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly com​posed of basalt. The inner core is made from Iron and Nickel.
