What is the second most abundant element on earth and seems to be very important in biological processes such as oxygen transportation in the body and cellular respiration
Answer:
iron
Explanation:
Cellular respiration may be defined as the group of metabolic processes as well as reactions which occurs in the cells of the organisms that converts the chemical energy from the oxygen molecules or from nutrients into ATP or adenosine triphosphate and then releases the waste products. Thus it breaks the glucose and produces the ATP. Iron is an important element which are used in many important biological processes in the body like the cellular respiration and oxygen transportation.

Potassium thiosulfate (K2S2O3) is used to remove any excess chlorine from fibers and fabrics that have been bleached with that gas. The reaction is K2S2O3 + 4Cl2+ 5H2O→2KHSO4 + 8HCl a. What mass of HCl will be produced at the same time that 45.0 g of KHSO4 is produced? (5 pst) b. What mass of Cl2 is consumed along with 2.20 x 1024 molecules of H2O? (5 pts)
Answer:
The correct answer is a) 48.16 grams of HCl will be produced, b) mass of chlorine consumed is 206 grams.
Explanation:
a) The reaction given is:
K₂S₂O₃ + 4Cl₂ + 5H₂O ⇒ 2KHSO₄ + 8HCl
Based on the given information, the mass of KHSO4 is 45 grams. The moles of KHSO4 can be determined by using the formula,
Moles = given mass/Molar mass
= 45/136.16
= 0.33 Moles of KHSO₄
From the reaction it can be seen that when 2 moles of KHSO₄ is produced, 8 moles of HCl is also produced. Therefore,
2 moles of KHSO₄ = 8 moles of HCl
So, moles of HCl will be,
Moles of HCl = 8 × 0.33/2
= 1.321 moles
Now the mass of HCl is,
Mass of HCl = Moles of HCl × Molar mass of HCl
= 1.321 × 36.46
= 48.16 grams of HCl
b) It is known that 1 mole is equal to 6.023 × 10²³ molecules
In the given case, the molecules of water is given, that is, 2.20 * 10²⁴ molecules. Now let us consider that the moles of water is x.
x mole of water = 2.20 × 10²⁴ /6.022 × 10²³
= 3.653 mole of H2O
From the reaction given, it can be seen that when 5 moles of water are consumed, 4 moles of chlorine are consumed.
5 moles of water = 4 moles of chlorine
3.653 moles H₂O = x moles of Cl₂
Moles of Cl₂ = 4 × 3.653 /5
= 2.906 moles Cl₂
Now the mass of Cl₂ determined as,
Mass of Cl₂ = moles of Cl₂ × Molar mass of Cl₂
= 2.906 × 70.9
= 206 grams
How do plant cells differ from animal cells
Answer: Plant cells have chlorophyll, chloroplasts, cell walls, a more blocky shape, and larger vacuoles. Animal cells have a more rounder shape, no cell wall but only a cell membrane, smaller vacuoles, and other organelles such has centrosomes, which plant cells don’t have.
Explanation:
Answer:
Plant and animal cells are different in that plant cells have chloroplasts and rigid cell walls, while animal cells do not.

Why is it difficult to know the impacts of deep sea mining?
O It has never been tried successfully, so we don't know exactly how it can be done.
Olt is only done in environmentally sensitive areas, where the organisms are being harmed in many ways already, and it is difficult to know the effects of mining.
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.

Answer:

Explanation:
We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.
Deep sea mining has never been tried successfully, so we don't know exactly how it can be done so it is difficult to know the impact of deep sea mining.
what is deep sea mining?The process of extracting and often excavating mineral deposits from the deep seafloor is known as deep-sea mining.
The deep bottom spans around two-thirds of the total seafloor and is found at ocean depths greater than 200 meters.
Deep-sea mining has been shown to affect marine biodiversity and ecosystems, but we still lack the knowledge and resources to safeguard them.
There are considerable gaps in our understanding of the deep sea's biodiversity and ecosystems since it is still understudied and poorly understood.
This makes assessing the possible effects of deep-sea mining and putting in place necessary safeguards to protect the marine ecosystem and the three billion people whose livelihoods rely on marine and coastal biodiversity challenging.
Hence , the correct option is A.

The Chatham Island robin is a small endangered bird found in scrub forests off the coast of New Zealand. The robin is preyed upon by introduced species such as cats and rats. In 1980, the population decreased to only 5 individuals and every individual today is a descendant of a single female. Which of the following is best illustrated in the decline of the Chatham Island robins?
1. Carrying capacity
2. Population bottleneck
3, Population overshoot
4. Type I survivorship
Answer: 2. Population bottleneck
Explanation:
A Population bottleneck is a term used to refer to an event that causes the population of a species to reduce in very large numbers. Such an event can be environmental disasters like famine, the overhunting of a species or the destruction of its habitat.
In the case of the Cha-tham Island Robin, the bottleneck event must have been the introduction of cats and rats which then went on to hunt the birds to near extinction.

Sea otters move into the ocean bay. The eat all the sea urchins. This change will cause the
A. Kelp to have less food
B. crabs to have less food
C. Sea ducks to have more food
D.Arctic foxes to have more food
The presence of sea otters in an ocean bay will result in a reduction in the amount of food available to carbs because they feed on sea urchins. Therefore, option (B) is correct.
What is food chain?The linear relationship between creatures that demonstrates how they obtain energy by feeding on one another is referred to as the food chain.
The information provided in this inquiry suggests that sea otters migrate into the ocean bay and consume all of the sea urchins there.
This leads one to believe that they cut down on the food supply of another eater of urchins, such as carbs. Because of this, the introduction of sea otters into the ocean bay will result in there being less food available for carbs.
