Explain how manganese and iron ores commonly form.
Answer:
The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters. This oxygen immediately combined with the abundant dissolved iron to produce hematite or magnetite. ... Steel Mill: Most iron ore is used to make steel.
The metal is obtained by reducing the oxide with sodium, magnesium or aluminium, or by the electrolysis of manganese sulfate. Manganese nodules have been found on the floor of the oceans. These nodules contain about 24% manganese, along with smaller amounts of many other elements.

A. Paraphrasing
B. Reflection
In North American forest, two species of birds, nuthatches and brown creepers, forage on the same trees for insects. Brown creepers feed on insects near the bottom of the tree trunk, while nuthatches feed on insects in the top part of the tree. The difference in foraging behavior most likely affects the nuthatches and brown creepers by: allowing birds to avoid many types of predators allowing birds to avoid many types of predators reducing competition between the birds for resources reducing competition between the birds for resources preventing the birds from interbreeding with each other preventing the birds from interbreeding with each other establishing dominance between the birds for nesting sites
Answer:
The correct answer is - reducing competition between the birds for resources.
Explanation:
In this ecosystem, the two species of birds brown creepers and nuthatches share habitat in the same tree for their food resources are insects. Brown creepers feed on resources on the bottom of the tree whereas nuthatches feed on the top of the tree.
By this, they avoid competition between these two birds for the same food resources in the same tree. The competition would be more if both have depended on the insects all over the tree.

Answer:
As during the civil war, African elephants with tusks were targeted, and the tuskless elephants were left alone. This, in turn, allowed for the tuskless elephant populace to thrive and continuously grow, while the tusked elephants saw a decline as more and more were poached. So, it is only natural that as time progresses, and assuming the circumstances remain constant, that the tusked elephant population will see a negative trend, and inversely the tuskless elephant population will see a positive trend.

Which process transfers energy from organisms at one stage in a food chain
to organisms at the next?
Tick the correct box.
reproduction
feeding
movement
photosynthesis
1 mark
Answer:
feeding
Explanation:
when an organism eats another, it gets energy from it. That energy is passed along the food chain
The process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.
What is the significance of the food chain and the energy transfer?The food chain in nature is made up of many trophic levels, where one trophic level animal preys on other animals or plants and obtains food from them, so when the animal is eaten by other animals, the energy content passes from one to another, and the energy content from plants continues to decrease to the topmost trophic levels.
Hence, the process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.

Vascular resistance is due to friction between blood and the walls of the blood vessel. Which of the following causes low vascular resistance?
obesity
dehydration
high blood pressure
cholesterol levels within normal range
Answer:
Cholesterol levels within normal range
Explanation:
Vascular resistance is due to friction between the blood and the walls of the blood vessel, and cholesterol levels within the normal range can cause low vascular resistance, which is the last option.
What is vascular resistance?Vascular resistance is the resistance to blood flow in the blood vessels, which is determined by the diameter of the blood vessels, blood viscosity, and the length of the blood vessels, so when blood flows through the blood vessels, it experiences frictional forces due to the interaction between the blood and the walls of the blood vessels, obesity, dehydration, and high blood pressure can all contribute to increased vascular resistance.
Hence, the correct answer is that cholesterol levels within the normal range can cause low vascular resistance, which is the last option.

Describe the three stages of cellular respiration and identify the part of the cell in which cach
stage takes place.
Answer: 3 stages- glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation. In glycolysis, the beginning process of all types of cellular respiration, two molecules of ATP are used to attach 2 phosphate groups to a glucose molecule, which is broken down into 2 separate 3-carbon PGAL molecules. PGAL releases electrons and hydrogen ions to the electron carrier molecule NADP+. A carboxyl group is removed from pyruvate and released as carbon dioxide. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH. The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA. The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step. Oxidative phosphorylation, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP. The space between the inner and outer membrane is called the intermembrane space. The space enclosed by the inner membrane is called the matrix. The second stage of cellular respiration, the Krebs cycle, takes place in the matrix. The third stage, electron transport, takes place on the inner membrane.
Explanation:
Which model of replication did the actual results of the Meselson-Stahl experiment support? Explain your answer.
Answer:
Semi-conservative replication
Explanation:
After the double-helix discovery of Watson and Crick, there were three possible models about the DNI replication:
The Conservative model stated that the two strands of DNI together were the template of another new molecule. The final product was the original double-stranded molecule and the new molecule. The semi-conservative model stated that the original DNI molecule separated into two strands, and each of them served as a template for the synthesis of a new complementary strand. The replication product would be two double-stranded DNA molecules, each carrying an original strand a new one. The Dispersive moles stated that the replication product would be two molecules made by a mixture of segments of the original and the new molecules.Meselson and Stahl joined to discover which of the models was the correct one. To do it they used E. coli and Nitrogen isotopes.
First, they extracted DNI from bacteria grown in a medium with N¹⁴ and got its density band by centrifugation. Then they grew bacteria in a medium with N¹⁵, extracted their DNI molecules, centrifugated them, and got the density band, which was heavier than the firsts ones. The researchers then transferred bacteria grown in medium with N¹⁵ to a medium with N¹⁴, and they allowed only one replication process to occur. DNI was extracted and centrifugated again, and a new band appeared. This band was an intermediate form between bands of DNI-N¹⁵ and DNI-N¹⁴.This event eliminated the conservative model. If this model were correct, the expected result would be to get two bands: one corresponding to the density DNI-N¹⁵ and the other corresponding to the density DNI-N¹⁴.
Bacteria grown in a medium with N¹⁵ and then transferred to a medium with N¹⁴ were finally allowed to replicate twice. Their DNI was extracted and centrifugated. The result was two bands: one of them coincided with the intermediate band, and the other one with the DNI-N¹⁴.This result was conclusive because if the dispersal model were correct, these two bands should not appear, as all the DNI strands would have part of the original molecule.
With this experiment, Meselson and Stahl proved that the correct replication model was the semi-conservative one.
