Answer:
Yes
Explanation:
, there’s merit to targeting children in marketing campaigns for high-calcium food. People reach peak bone mass at about age 30. If children don’t consume enough calcium, they may not build up enough bone density, which could cause them to be at risk for osteoporosis when they’re older.
There is a lot of merit in telling children to get their calcium in building strong bones because the increase in bone density by calcium stops between 25-30 years.
It is therefore for the children to take enough of calcium to make their bones
very dense and strong as attaining the age of 30 years means there will be
no change in the bone density regardless of the amount of calcium taken.
Intake of calcium at an early age also helps us plan for old age . At the age of
50 years and above , individual experiences bone loss which leads to
osteoathritis and other bone related diseases.

The introduction of zebra mussels in the Great Lakes is an example of which type of release? The introduction of zebra mussels in the Great Lakes is an example of release.
The introduction of zebra mussels in the Great Lakes is an example of accidental release from ballast water in a foreign container ship.
Answer:
The introduction of zebra mussels in the Great Lakes is an example of an unintentional or accidental release.
Explanation:
The zebra mussel known biologically as Dreissera Polymorph's, is a small freshwater mussel which its species was originally from the lakes in Southern Russia and Ukraine. Known globally as invasive species, they got their name through the striped pattern which are mostly seen on their shells.
Zebra mussels were noticed in Canada in the Great Lakes in 1988 at lake St. Clair. They were believed to be unintentionally released into the lakes in the ballast water of ships going to oceans, traveling the St. Lawrence Seaway. Another belief was linked to the introduction or release through anchors and chains even though this belief has been described as mere speculation.

What is photosynthesis?Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it gains electrons, inside the plant cell.
Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.
Both light-dependent and light-independent processes. As suggested by its name, the light-dependent reaction takes place inside the thylakoid membrane and requires a steady stream of sunlight.
Therefore, With a specific range of conditions is supported by the evidence is the correct option.

The tundra is cold year-round it has short cool summers and tong, severe winters. The tundra has a permanently frozen sublayer of soil called permafrost. Like the desert, the tundra receives little precipitation, about 4 to 10 inches per year, and what does fall is usually in the form of snow or ice. It has long days during the growing season, sometimes with 24 hours of daylight and long nights during the winter. Which adaptations would you expect to see in plants growing in the tundra?
With plants on the tundra, you would expect to see many Short-growing plants with Waxy coatings along with Fine hair-like structures. Each of those features help tundra plants withstand the cold and drying effects of the wind in those regions.

Apple maggots are a type of fly native to North America. Prior to the introduction of the apple tree to North America, apple maggots fed from and laid their eggs in hawthorn trees. After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees. Adult apple maggots will only mate on the type of tree on which they were born.
What is the most likely consequence of the introduction of apple trees to apple maggots?
A. Some apple maggots will undergo adaptive radiation to colonize many other types of trees besides the apple and hawthorn .
B. Populations of apple maggots that mate on different trees could become reproductively isolated and eventually speciate.
C. Apple maggots that are born on apple trees will be unable to reproduce and will eventually die out.
D. Individual apple maggots will eventually learn to lay eggs on both hawthorn trees and apple trees.
your answer is b hope this helps
The correct answer is option B
The population of maggots on the apple tree (apple maggot) that will mate on different trees could become reproductively isolated due to different habitat (ecological isolation).
Ecological isolation causes speciation by creating reproductive barriers between populations due to different habitats.The maggot populations will mate on different trees and will eventually speciate over a period of time.
You want to cultivate some exotic plants at your farm. However, the climate is chillier than the temperature range favorable to the crop. Which is the best method to use for the cultivation of this exotic crop?
A. use a crop rotation method B. use a lot of fertilizer C. prepare the seed bed properly D. use a greenhouse E. use irrigation
The correct answer is - D. use a greenhouse.
If the climate is not suitable for a certain exotic plant, and the reason for that is that it is colder than the place from where the plant originates, than the best solution is to plant it in a greenhouse.
The greenhouse will provide higher temperature for the plant throughout the whole year, so it is will have a proper temperature, similar to the one it is adapted to. Also, it will receive sufficient amounts of light. It will be protected from the outside influences such as the cold winds, snow, low temperatures, so it will have a good chance of growing.

The stem cells of embryo are mainly pleuripotent and multipotent that can form cells of different lineages.
Why do plants rely on photosynthesis and cellular respiration for energy but animals only rely on cellular respiration
Animals do not need the sun. Animals need glucose or whatever quick energy they can live on
Plants and animals both rely on cellular respiration for energy, but only plants perform photosynthesis to create the glucose needed for cellular respiration. Animals must consume food to get the glucose they need.
Explanation:Plants and animals both rely on cellular respiration to produce ATP, a form of chemical energy that cells can use. However, while animals take in food that they then break down to fuel cellular respiration, plants generate their own food through a process called photosynthesis.
In photosynthesis, plants convert sunlight, carbon dioxide, and water into glucose. This glucose can then be used in cellular respiration to produce ATP. In other words, photosynthesis enables plants to create the fuel they need for cellular respiration.
Animals, on the other hand, do not have the capability to do photosynthesis. They cannot convert sunlight into chemical energy, so they must rely on consuming food to get the glucose they need for cellular respiration.

How does pain relievers work
When you take a pain reliever like ibuprofen, it keeps injured or damaged cells from making and releasing prostaglandin. When the cells don't release this chemical, it means that the brain won't get the pain message as quickly or clearly.
Pain reliever works by holding infected cells of secreting prostaglandin. It is primarily not produced and there will be no stimulus which will happen to feel the pain in the living organism. If someone takes a pain reliever then he will not feel pain because the cells will not send the stimulus to the brain hence the human body will not feel pain. Acetaminophen and ibuprofen are examples of pain reliever that are commonly used.

Therefore, option B is correct.
What is friction?The resistance to motion created when two objects rub against one another is called friction. Friction occurs whenever two items come into contact with one another. Friction acts in the opposite direction from the motion and works against it. The two surfaces' respective materials have an impact on how much friction exists.
The force that prevents one solid item from moving across another is known as friction. Static friction, sliding friction, rolling friction, and fluid friction are the four main categories of friction. It is a contact force that acts between two surfaces.

what are the two factors that create the difference between the temperate forest biome in the taiga biome
The temperate forest biome covers latitudes ranging approximately from the southern United States to southern Canada, while the taiga biome, also known as boreal forest, extends from the latitude of southern Canada to about 60 degrees north latitude. (see References 1, References 3) Thus, these two biomes are adjacent, which explains the many similarities between taiga and northern temperate forests. Both biomes have four distinct seasons, but the temperate forest climates cover a much wider range of temperatures and precipitation patterns. Taiga, in contrast, is reliably cold: most of the precipitation falls as snow, winters are severe and the growing season is short -- about 130 days compared to 140 to 200 days for temperate forests.
The two factors that create the difference between the temperate forest biome and the taiga biome are as follows:
Temperature.Precipitation. What is a biome?A biome may be characterized as a very large ecosystem that is consistently running in nature in an unmanaged way. In more simple words, it is defined as a very large area that is characterized by a particular type of vegetation. Some examples of biome may include tropical rainforests, coral reefs, grasslands, etc.
Taiga biomes are generally thick forests. Coniferous trees, such as spruce, pine, and fir, are common. These trees have needles instead of broad leaves, and their seeds grow inside protective, woody cones.
While temperate forests have deciduous trees which lose their leaves in winter, conifers never lose their needles. All such differences are created by numerous factors but temperature and precipitation are the most potent ones.
Therefore, temperature and precipitation are the two factors that create the difference between the temperate forest biome and the taiga biome.

B) Stereoscope microscope
C) Scanning electron microscope
D) Simple microscope
C.) Scanning electron microscope. You would not be able to see a whole insect with one of these.
Hope this helped :)
To observe a whole insect, a Compound light microscope would not be suitable since it's designed for viewing small, transparent samples at high magnification. A stereoscope microscope, which allows light to shine onto the specimen, is more appropriate for such observations.
Explanation:To see a whole insect under a microscope, you would probably not use a Compound light microscope. The correct tool for observing entire insects is a stereoscope microscope, also known as a dissecting microscope, which uses incident light to shine onto the specimen. This is because compound light microscopes are designed for viewing small samples at high magnifications with light passing through the specimen, which is not ideal for whole insects. Moreover, scanning electron microscopes provide detailed images of the surface of specimens but are not suitable for observing entire, live insects. Simple microscopes, offering a single lens for magnification, also do not suit the demands of viewing a whole insect in detail.
