Answer:

Carbon pollution is changing the ocean's chemistry, slowing its ability to uptake CO2, making it more acidic, and harming shellfish and other marine life we depend on. The ocean has absorbed about 29 percent of global CO2 emissions since the end of the preindustrial era.Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming.

1: For example, rhinovirus has over 100 different serotypes. Now, the good news is that you can't get ill from the same virus serotype right after getting better, due to the fact that you'll have developed antibodies which help to protect your immune system for a little while.

2:Most children in the United States are now vaccinated against measles virus; before vaccination was widespread, most were naturally exposed to this virus and suffered from an acute, unpleasant, and potentially dangerous viral illness. Whether through vaccination or infection, children exposed to the virus acquire long-term protection from measles. The same is true of many other acute infectious diseases: this state of protection is a consequence of immunological memory.

The basis of immunological memory has been hard to explore experimentally. Although the phenomenon was first recorded by the ancient Greeks and has been exploited routinely in vaccination programs for over 200 years, it is just now becoming clear that memory reflects a persistent population of specialized memory cells that is independent of the continued persistence of the original antigen that induced them. This mechanism of maintaining memory is consistent with the finding that only individuals who were themselves previously exposed to a given infectious agent are immune, and that memory is not dependent on repeated exposure to infection as a result of contacts with other infected individuals. This was established by observations made on remote island populations, where a virus such as measles can cause an epidemic, infecting all people living on the island at that time, after which the virus disappears for many years. On reintroduction from outside the island, the virus does not affect the original population but causes disease in those people born since the first epidemic. This means that immunological memory need not be maintained by repeated exposure to infectious virus

Answer:

List the phases for Meiosis I: Prophase I, Metaphase I, Anaphase I, Telephase I

List the phases for Meiosis II: Prophase II, Metaphase II, Anaphase II, Telephase II

During prophase I the chromosomes coil and become shorter.

Chromosomes that are the same size and have the same genes are called homologous chromosomes.

Each half of a replicated chromosome is called a chromatid.

Sister chromatids of a chromosome are identical copies of the same chromosome.

Answer:

The answer would be B. Mangrove Swamps

Explanation:

Brackish water is when freshwater meets with sewer water or salty water.  

Brackish water can be found in the mangrove swamps ecosystem.

They are marked by halophytic trees, shrubs and different flora thriving in saline to saline tidal waters.

Mangrove forests, also named mangrove swamps, mangrove shrubs or trees, are formative wetlands that appear inshore intertidal zones. Mangrove forests grow mainly in equatorial and subtropical spaces because mangrove trees cannot resist freezing .

It is distinguished by such qualities as a damp climate, saline habitat, waterlogged soil or sludgy soil.

Thus, Brackish water can be found in the mangrove swamps ecosystem.

Answer:

I would need the statements to answer that. however prokaryotic cells are plant cells and eukaryotic cells are animal cells

Answer:

They are typically smaller than eukaryotic cells. The DNA of a prokaryotic cell is contained in the nucleoid. There are several ways in which prokaryotic cells are different from eukaryotic cells. Firstly, they are generally smaller in size, their organelles are not membrane bound, and they have no nucleus. They, however, share commonalities with eukaryotic cells including the presence of a bilipid plasma membrane, presence of ribosomes and DNA.

Answer:

I think the answer is gonna be B

Explanation:

During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands' inhabitants.

Among those that struck Darwin so greatly were the finches that are now named in his honor. Darwin would later base some of his thought from the supposing that these finches were all descendents of the same lineage.

Answer:

The total travelled distance is [tex]51065 \mathrm{~m}[/tex]

Explanation:

• Speed, time and distance is one of the most common and important topics in the Mathematics or Quant section.

• Calculate total speed;

[tex]\therefore \text { Total Speed }=2+0.5+0.0+1=3.5 \mathrm{~m} / \mathrm{sec}[/tex]

• Calculate total time taken;

[tex]\therefore \text { Total time taken }=120+30+40+14400=14590 \mathrm{sec}[/tex]

• To find total travelled distance, use the formula

[tex]\text { Distance }=\text { Speed } \times \text { Time }[/tex]

[tex]\mathrm{d} &=3.5 \times 14590 \\[/tex]

[tex]&=51065 \mathrm{~m}[/tex]

Renewable resources are resilient to environmental stress. Therefore, option "C" is correct.

The energy produced by natural resources such sun and water is known as renewable resources. They are never finishing forms of energy and can be continuously replenished.

As non-renewable resources are on the verge of vanishing, there is an urgent need to innovate renewable sources of energy. The types of renewable resources are solar energy, wind energy, hydro energy, thermal energy, and biomass energy.

The benefits of renewable energy are less pollution, reusable sources of energy, less production of greenhouse gasses, and being environmentally friendly.

Renewable resources are more sustainable than non-renewable resources.

Answer:  According to the first law of thermodynamics, energy can be transferred from place to place or changed between different forms, but it cannot be created or destroyed. For instance, light bulbs transform electrical energy into light energy, and gas stoves transform chemical energy from natural gas into heat energy.

Explanation:

Answer: The first law of thermodynamics states that: energy can neither be destroyed or created, it can only change forms. An example of this in an ecosystem would be when a plant absorbs the sun's energy and photosynthesizes, storing the energy as glucose.

Answer:

A

Explanation:

A human liver cell would have a different size and shape from a human muscle cell because they perform different functions in the body.

The shape a cell would assume and its size depends on the function the cell performs. The functions of the liver in the body of humans differ greatly from the functions of muscles. While the former helps in detoxification, deamination, digestion, etc., the latter helps in support, movement, etc.

The correct option is A.

A human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.

Answer:

Explanation:

In the upper thermosphere, atomic oxygen (O), atomic nitrogen (N), and helium (He) are the main components of air.

The potassium ions are positively charged(cations) if the charge is -70mV the outflow of cations will cause a decrease in the potential. The potential will become lower than -70mV.

The given condition of an increase in the movement of potassium ions out of that neuron's cytoplasm would result in the hyperpolarization of the neuron.

Hyperpolarization is a change in a cell's membrane potential becomes more negative at a particular spot on the neuron's membrane

Thus, the correct answer would be the hyperpolarization of the neuron.

Answer:

A population of mosquitoes develops resistance to a pesticide

Explanation:

Evolution can be defined as the way the characteristics of a species change over several generations. This process relies on natural selection - a mechanism in which individuals that are better adapted to their environment survive and reproduce most successfully.

A population of mosquitoes developing resistance to a pesticide is an example of adaptation. This is how mosquitoes become adapted to their environment and increase their chances of survival. Eventually, most of the mosquitoes will be resistant thanks to natural selection. This is how mosquitoes evolve.

This is why the fourth option is the correct one.
