Because we can't see through a gas cloud, we would not use optical telescopes which collect
visible light to form images of stars inside a gas cloud. Which type of telescope would we use
to study new stars inside the giant gas cloud and why?
ANSWER ASAP
Answer: radio telescopes can be used.
Explanation:
Radio telescopes can be used to see through the dust and the star being born. The stars are born into clouds of gases in the space. Due to gravity more and more gas get collected and it forms a clump. When the clump get big enough the hydrogen atom crash each other to form the helium. The clump of gas becomes a star. The radio telescopes can be used to take pictures of these stars within the clump of gas. It can also be used to take picture of fusion of gases within a star to initiate the formation of new star.
Answer:
It's an infrared telescope.
Explanation:
We can't rely on an optical telescope since it only shows what we can see. In turn, we can use an infrared telescope because it allows us to see heat. We can use this heat to study celestial bodies, stars, and gases.

B. foaming agents or plastics releasing chloroflourocarbons
C. excessive carbon dioxide blanketing the earth
D. overuse of nitrogen-containing materials polluting bodies of water
Answer:
B. foaming agents or plastics releasing chloroflourocarbons
Explanation:
Causes : chlorofluorocarbon (CFCs), halons, and other compounds deplete the ozone layer. These chemicals are found in cleaning agents, aerosols, insulating foam, and refrigerants. CFCs and halons break down into chlorine and bromine which in turn destroy the ozone layer.
Answer:
Hello There. The correct answer is C. excessive carbon dioxide blanketing the Earth.
Explanation:
Because it means that Carbon dioxide spreads around the planet like a blanket, and is one of the main gases responsible for the absorption of infrared radiation (felt as heat), which comprises the bulk of solar energy. Hope It Helps! .ω.
Sam is investigating the factors that affect photosynthesis. She keeps some plants in the dark for 24 - 48 hours. They receive no light. What does this remove from the plants?
Answer:
In photosynthesis, sunlight is necessary for it allows the plant to synthesize food from the CO2 and water. Without the light, it cannot carry out photosynthesis and create the food to feed itself.
By keeping some plants in the dark, Sam is removing the ability of the plant to capture light for photosynthesis.
Photosynthesis is a process whereby green plants capture light energy for the synthesis of carbohydrates using inorganic raw materials such as water and carbon dioxide.
The process of photosynthesis takes place in 2 major steps
Light-dependent reactionLight-independent reactionDuring light-dependent reaction, energy from light excites chlorophyll molecules and cause an electron to be displaced. The electron in the chlorophyll is replaced by the electron in water, leading to the cleavage of the bond between H and O and the evolution of O2. ATP and NADPH are produced and these are utilized in the light-independent reaction.
In the light-independent reaction, the molecules synthesized from the light-dependent reaction are used to fix carbon dioxide in a series of reactions resulting in the formation of carbohydrates.
Hence, keeping some plants in the dark will alt the light-dependent reaction and the entire photosynthesis process at large.

Describe the life cycle of amphibians using an example.
Answer:
In typical amphibian development, eggs are laid in water and larvae are adapted to an aquatic lifestyle. Frogs, toads, and newts all hatch from the eggs as larvae with external gills but it will take some time for the amphibians to interact outside with pulmonary respiration. Afterwards, newt larvae start a predatory lifestyle, while tadpoles mostly scrape food off surfaces with their tooth ridges.

B. Red pandas and raccoons share a more recent common ancestor
than red pandas and giant pandas.
C. Raccoons descended from red pandas.
D. Red pandas descended from giant pandas.
Answer:
B. Red pandas and raccoons share a more recent common ancestor
than red pandas and giant pandas.
Explanation:
DNA sequencing is finding the sequence of base pairs in an organism's DNA, and it's often used to compare with other organisms. The more base pairs that are the same, the more similar the two organisms are, and this means that they share a more recent common ancestor.
We can't make any conclusions like C and D because we just don't have enough data to conclude that one descended from the other.
Answer: B
Explanation:
Red pandas and raccoons share a more recent common ancestor.
There appears to be some relationship between population density and the presence of large dead zones. Can you explain why dead zones seem to be more prominent in areas of high
population density
Nitrogen and phosphorus runoff from sewage and agricultural activities in high population centers leads to the formation of dead zones.
People in these high population areas have over fished their coastal waters, leading
dead zones
The abundance of cruise ships in these high population centers results in the production of large amounts of pollution, leading to the formation of dead zones.
This is a random correlation and not a result of population centers causing the dead zones
Answer: Dead zones can be defined as an area of significant pollution.
Explanation:
Dead zones are associated with waters with low-oxygen content and the organisms suffer from hypoxic conditions. These areas include the waters of oceans, lakes and other types of water bodies.
The dead zones are created due to human activities. The high density population of human kind require space to survive. They use and contaminate the nearby source of water body. The agriculture pollutants contains fertilizers and pesticides which contains nitrogen and phosphorus that runoff into the water body. Also the sewage discharge also increases the nitrogen content in nearby source. Thus makes the water body oxygen deficient.
The large population of human kind may depend on fishery as source of food thus they may create a dead zone in nearby water body by overfishing and depleting the population to a level of zero.
The cruise may introduce oil contaminants in the water body which can reduce the oxygen availability of the water hence, kill the organism and create a dead zone.
Answer: Nitrogen and phosphorus runoff from sewage and agricultural activities in high population centers leads to the formation of dead zones.

which of the following best describes the changes that take place in an ecosystem during primary succession
The given question is incomplete, the complete question is:
Which of the following best describes the changes that take place in an ecosystem during primary succession?
Lichens and mosses grow slowly on newly formed land, followed by grasses, shrubs, and trees.
Shrubs and trees regrow quickly in areas that have been disturbed by a forest fire.
Organisms compete for resources, and those that are best fit to survive establish themselves as the dominant species.
Natural disasters cause many populations to migrate to a new location in order to survive
Answer:
The correct answer is that the growth of lichens and mosses takes place gradually on the freshly formed land, and is succeeded by shrubs, grasses, and trees.
Explanation:
An array of changes that takes place within an ecosystem's biotic community with regard to modifications that occurs with time within the non-living constituents of an ecosystem until stability is attained within the ecosystem is termed as ecological succession. A succession, which takes place in a previous barren land where there is no existence of life is known as primary succession.
For example, a gradual growth of mosses and lichens on a freshly formed land, succeeded by shrubs, grasses, and trees is an illustration of primary succession. The pioneer species like mosses and lichens possesses the tendency to grow on the land, that is, not inhabited previously by any other species of plant and further helps in the growth of novel species of plants.
On the bare rocks, lichens discharge acids that assist in the process of rock withering as it reduces the compaction of the rocks. Further, the aggregation of soil takes place that facilitates the growth of mosses. Eventually, the mosses help in bettering the quality of the soil, which further helps in the growth of shrubs, grasses, and trees.
Answer: Explanation:
The person who asked this question didn't put any choices, so I am going to give you some examples of primary and secondary successions.
First what is primary and secondary succession?
Primary succession: it is the profession of growth, it developed on newly formed land.
Secondary succession: it is the redevelopment of a habitat that has been disturbed by an event such as a forest fire or a hurricane. “Tsunami, earthquake, or forest fire”
If you have answer choices like these(A) Lichens and mosses grow slowly on newly formed land, followed by grasses, shrubs, and trees.
(B) Shrubs and trees regrow quickly in areas that have been disturbed by a forest fire.
(C) Organisms compete for resources, and those that are best fit to survive establish themselves as the dominant species.
(D) Natural disasters cause many populations to migrate to a new location in order to survive.
Then your answer is:(A) Lichens and mosses grow slowly on newly formed land, followed by grasses, shrubs, and trees.
Why not the other choices?
Because; "(B) Shrubs and trees regrow quickly in areas that have been disturbed by a forest fire" That is secondary succession, (redevelopment of a habitat that has been disturbed)
Because; "(C) Organisms compete for resources, and those that are best fit to survive establish themselves as the dominant species." Just doesn't fit the description for either Primary or secondary succession.
Because; "(D) Natural disasters cause many populations to migrate to a new location in order to survive." That isn't either Primary or secondary succession because Primary succession is "newly growth" and secondary succession is "redeveloped habitat".

Outline the phases of the menstrual cycle, or the period in woman. please this should be at least 150 words. I will mark as BRIANILIST, please don't copy from Google, thank you.
Answer:
Menstruation, the follicular process, the ovulation and the luteal period are the four stages of the menstrual cycle. Specific menstrual complications include extreme or painful spells and a premenstrual syndrome (PMS). Knowing that a woman is most likely to conceive in the menstrual cycle can increase the chance of pregnancy. in simpler words, Bleeding phase, Pre-fertile phase, Fertile phase, Releasing an egg (ovulation), Post-fertile phase.Estrogen rates increase and fall periodically during the menstrual cycle. Estrogen rates increase during the mid-follicular process, then drop precipitously after ovulation. This is followed by a secondary increase in estrogen levels during the mid-UT phase, with a decrease at the end of the menstrual cycle.Elevated levels of estrogen are a risk factor for breast and ovarian cancer. High levels of estrogen can increase your risk of blood clots and stroke. Estrogen superiority can also improve the risk of developing a thyroid disorder. This may contribute to signs such as exhaustion and increases in weight.
