Why is ocean acidification dangerous?2-3 complete sentences
Answer:
Carbonate is important to marine life, especially those with exoskeletons and shells, who form their protective casings from carbonate. Ocean acidification reduces the amount of available carbonate, and can cause their shells to crumble and dissolve. Animals then have to spend extra energy either repairing their shells or thickening them to survive.
1. A cool piece of iron gets warm when a red-hot piece of iron is placed a few inches
away. How is heat transferred in this scenario?
Answer:
Convection currents in the air between the pieces of metal transfer all the heat. The air between the two pieces of iron emits thermal radiation that is absorbed by the cool iron.
There you go, hope this helped.
Heat energy is transferred from one matter to another through various modes and methods. A cool iron piece heats due to convection that transferred the heat from the hot iron.
What is convection?Convection has been one of the modes of thermal heat transformation that uses matter to transfer the heat from higher to lower concentrations, unlike the radiation mode. The matter particles move from hot to lower temperatures.
The air present between the cold and hot iron piece acts as the medium by which the cold iron piece absorbs the heat transferred by the hot iron piece. This thermal energy is emitted and absorbed due to the difference in temperature.
Therefore, the process of convection facilitates the thermal heat transformation from hot to cold iron objects.

Considering the most important ecological issue of the future, what is the biggest challenge the world will face in its dedication to conservation and restoration in the future?
The number of species in an extinction vortex
Spread of disease and parasites via corridors
The amount of land and energy resources
The pressures of its growing population
Answer:
its the amount of land and energy resources or the pressure of its growing population.
Explanation:
It is likely that the biggest challenge the world will face in its dedication to conservation and restoration in the future will be the pressures of its growing population, which is the last option.
What is population growth?As the population grows, there will be an increased demand for food, water, energy, and land, which will lead to habitat loss, deforestation, pollution, and climate change. These factors can exacerbate other ecological issues, such as the number of species in an extinction vortex and the spread of disease and parasites via corridors. Therefore, it is crucial to address the root cause of these problems by promoting sustainable practices and reducing our impact on the environment.
Hence, it is likely that the biggest challenge the world will face in its dedication to conservation and restoration in the future will be the pressures of its growing population, which is the last option.

1. State three ways in which protein are important to plant
(3marks)
Proteins are important in plants in order to synthesize cellular components (e.g., organelles), provide structural support cytoskeleton) and carry to metabolic reactions (enzymes).
Proteins are fundamental biomolecules composed of amino acids linked by peptide bonds.In cells, proteins can play diverse structural and enzymatic roles.For example, structural proteins are required to synthesize ribosomes, which serve to assemble other proteins that form the cytoskeleton of cells. Moreover, enzymes are proteins capable of catalyzing chemical reactions such as photosynthetic reactions.In conclusion, proteins are important in plants in order to synthesize cellular components (e.g., organelles), provide structural support cytoskeleton) and carry to metabolic reactions (enzymes).

9. In order to grow two of the exact same plants, a person would reproduce them asexually because the
a) genetic diversity is greater. b).offspring would be genetically identical. c. recessive traits would emerge d). negative traits are suppressed.
Answer:
b).offspring would be genetically identical.
Explanation:
To grow the exact same plants, a person would reproduce asexually because the offspring would be genetically identical. Hence, the correct answer is option b.
What are the different modes of reproduction?There are two different types of reproduction: sexual reproduction and asexual reproduction. In sexual reproduction, the offspring that are formed are slightly different from the parents. This is due to meiotic cell division. Variations in offspring are seen as a result of gene crossing over.
In asexual reproduction, all the offspring are identical to the parents. It is similar to mitosis. Recombination and crossing over do not occur here.So in order to get the exact same plant, this type of reproduction is done by taking a branch from a tree, etc. Others are incorrect statement options.
Hence, to get the exact same plants, a person should go for asexual reproduction, as they produce genetically identical offspring. Option b is the correct answer.

Describe how each of Newton’s laws may be observable during a car trip.
If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest. Additionally, if a car was moving straight when another car struck it, the direction of the car would shift.
What are newton's three law of motions ?According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
There's a fourth law , it states that every object tends to remain in the state it is in right now. We refer to this propensity as inertia. Every object tends to remain in the state it is in right now.
Therefore, If the seat belts on any passengers are fastened, the vehicle will also slow down until everyone is at rest (First law) . Additionally, if a car was moving straight when another car struck it, the direction of the car would shift (Third law).

Two frog populations (same species) living in two neighboring lakes sing slightly different courtship songs. Increased irrigation makes the land between the two lakes wetter, allowing frogs to expand their ranges to the area between the lakes. Females in both populations prefer loud frogs to quieter frogs but do not distinguish between the two slightly different songs. Assuming that courtship song differences have a genetic basis, predict what will likely happen to the songs of the two frog populations.
A. You cannot predict a change in the courtship songs at the two lakes.
B. Disruptive selection will cause the songs to differentiate even more.
C. The songs will become more similar to each other.
D. Males will become louder.
E. Genetic drift will cause the songs to differentiate even more.
Answer:
C. The songs will become more similar to each other.
Explanation:
To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.
One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.
So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.
The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.
Explain how and why you would conduct a study to determine if this bone can be used to determine sex
Answer:
The pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably. Males have a square jawline and the line between the outer edge of the jaw and the ear is vertical. Conversely, in females the jaw is much more pointed and the edge of the jaw slopes gently towards the ear.
