An event happens that decreases the number of earthworms, spiders, and insects in an area. How would you expect the event to affect to the number of long-billed curlews in the same area? (1 point) O It would not be affected. O It would stay the same. 0 It would increase. It would decrease.
Long-billed curlews feed on insects and worms mainly. Thus, their population will drastically reduce if there is a decrease in their food availability.
Factors affecting the population of organismsOne of the factors that affect the population size of a species is food availability.
Inadequate food increases intraspecies competition and results in more deaths. This leads to a reduction in the population size.
Long-billed curlews are a species of bird that feeds on insects and worms when inland. If an event leads to a decrease in the number of earthworms, spiders, and insects in an area, this will greatly reduce the population of long-billed curlews.

Organisms that live in the water (ocean, rivers, intertidal zones) must be adapted for changing conditions. Describe at least one (1) adaptation that organisms living in an aquatic ecosystem might have and how it helps the organism to survive.
One adaptation that organisms living in an aquatic ecosystem might have is the ability to regulate their salt concentration.
What are organism?Organisms are living species that live on the planet earth.
There are types of organisms categorized by the environment they live.
Organism that can survive only in water is called an aquatic organism.
We have,
One adaptation that organisms living in an aquatic ecosystem might have is the ability to regulate their salt concentration.
Aquatic environments can have varying levels of salinity, and some organisms need to maintain a specific salt concentration in their bodies to survive.
For example, marine fish have kidneys that can produce very concentrated urine to prevent them from losing too much salt in their surroundings, while freshwater fish have specialized cells in their gills that actively pump salt out of their bodies to maintain the appropriate balance.
Similarly,
Some marine invertebrates, such as crabs and mussels, can regulate the amount of salt they take in by actively transporting ions across their gills or other specialized structures.
This adaptation helps the organism to maintain the proper fluid balance and avoid dehydration or over-hydration, which can be lethal.
Thus,
One adaptation that organisms living in an aquatic ecosystem might have is the ability to regulate their salt concentration.

How many grams of Al2O3are present in 7.1 x 10^22 molecules of Al2O3?
Answer:
13.4g
Explanation:
we know that:
1 mole = 6.02 × 10²³ atoms
make the unknown number of moles = x
x = 7.1 × 10²² atoms
putting them both together:
1 mole = 6.02 × 10²³ atoms
x = 7.1 × 10²² atoms
Cross multiply:
6.02 × 10²³ x = 7.1 × 10²²
divide both sides by 6.02 × 10²³
[tex]x = \frac{7.1 \times 10²² }{ 6.02 × 10²³} [/tex]
[tex]x = \frac{71}{602} [/tex]
we now have the number of moles of Al₂CO₃
to calculate the grams (mass):
[tex]moles = \frac{mass}{relative \: formula \: mass} [/tex]
[tex]mass = moles \: \times \: relative \: formula \: mass[/tex]
add up all of the atomic masses of Al₂CO₃ to calculate relative formula mass:
(27 × 2) + 12 + (16 × 3) = 114
the grams (mass) of Al₂CO₃:
[tex] \frac{71}{602} \times 114 = 13.4g[/tex]

How many moles of H2O2 are produced in the production of hydrogen peroxide when 13 grams of oxygen are used
Identify the solution that is likely to have the greatest concentration of H . Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices orange juice ammonia pure water bleach blood
From what we know, we can confirm that the solution that is likely to have the greatest concentration of H+ is orange juice.
This has to do with the effects of H+ in a substance. The presence of hydrogen ions causes the substance to be more acidic, and the higher the concentration the higher the acidity of the substance. Since orange juice is the only acidic solution listed, we can know it will have the highest concentration of H+ ions.
Therefore, due to its acidic nature, we can confirm that the solution that is likely to have the greatest concentration of H+ is orange juice.

The electron configuration of element Y ends in s?p4. What is
the symbol for the ion most commonly formed by this element?
a y2+
b y2-
с ү6+
d Y
This problem is providing us with the end of the electron configuration an element as s²p⁴ and asks for the most commonly formed ion. At the end, the answer is b Y²⁻.
Electron configurationIn chemistry, when analyzing electron configurations, one must first take into account how the energy levels must be filled with electrons.
Now, note the problem states that the electron configuration ends by s²p⁴, which means it is closer to complete the octet so it needs two electrons in order to do so, as it behaves as a nonmetal.
Therefore, the most commonly ion formed by this element is Y²⁻, because of the fact that it needs two electrons to complete the octet and thus become chemically stable and likely to bond with a metal.
