Need 11 facts about solar eclipse
1-The longest a total solar eclipse can last is 7.5 minutes.
2-The width of the path of totality is usually about 160 km across and can sweep across an area of Earth's surface about 10,000 miles long.
3-Almost identical eclipses occur after 18 years and 11 days.
4-This period of 223 synodic months is called a saros.
5-Each year there are between 2 and 5 solar eclipses.
6-The total solar eclipse, when the Moon completely obscures the Sun and leaves only the faint solar corona, is known as a Totality.
7-Total solar eclipses are rare, happening only once every 18 months.
8-Total solar eclipses produce harmful rays that can cause blindness.
9-If any planets are in the sky at the time of a total solar eclipse, they can be seen as points of light.
10-During a total solar eclipse, conditions in the path of totality can change quickly. Air temperatures drop and the immediate area becomes dark.
11- A solar eclipse can only occur when the Moon is close enough to the ecliptic plane during a new moon
Answer:
1-The longest a total solar eclipse can last is 7.5 minutes.
2-The width of the path of totality is usually about 160 km across and can sweep across an area of Earth's surface about 10,000 miles long.
3-Depending on the geometry of the Sun, Moon, and Earth, there can be between 2 and 5 solar eclipses each year.
4-A total solar eclipse can happen once every 1-2 years. This makes them very rare events.
5-Almost identical eclipses occur after 18 years and 11 days. This period of 223 synodic months is called a saros.
6-During a total solar eclipse, conditions in the path of totality can change quickly. Air temperatures drop and the immediate area becomes dark.
7-There is another type of solar eclipse, known as a hybrid eclipse, which shifts between a total and annular eclipse depending on where you view it from on Earth. These are comparatively rare.
8-The speed of the Moon as it moves across the Sun is approximately 2,250 km (1,398 miles) per hour.
9-If you are at the North or South Poles, you cannot view a total solar eclipse.
10-In ancient times, people thought an eclipse was a sign that the gods were angry or that bad things were about to happen.
11-During a total solar eclipse day time looks more like twilight.

what happens to the 90% of energy available if 10% moves on to the next trophic level
Answer:
Released as heat
Explanation:
The vast majority of energy in the ecosystem is used by the organisms to power chemical reactions in the cell.
Therefore, this energy is lost as heat when it powers metabolic processes, rather than being passed on to the next trophic level.
Select the answer below that describes the process of photosynthesis
photosynthesis is when humans convert their food into energy
photosynthesis is when plants convert sunlight, water and carbon dioxide into energy
photosynthesis is when plants convert sunlight, water and oxygen into energy
photosynthesis is how plants grow
Answer:
Photosynthesis is when plants convert sunlight, water, and oxygen into energy.
photosynthesis is how plants grow
Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere and supplies most of the energy necessary for life on Earth.

Salmonella typhi is a bacteria that reproduces by splitting into two
identical organisms. What type of asexual reproduction is this?
1Binary Fission
2O Vegetative Propagation
3Budding
4Fragmentation
Answer:
Binary fission
Explanation:
Binary fission is a type of asexual reproduction in bacteria in which two identical daughter cells arise from a new cell. It is asexual in the sense that it does not require two parents but only one.
According to this question, Salmonella typhi is a bacteria that reproduces by splitting into two identical organisms. This is evidently a type of BINARY FISSION reproduction by the bacteria cell.
5. A herd of zebras has 9 males and 62 females.
During a one-year period, 22 foals that are born
survive and 25 adults die. Six females join the
herd. Three males and 11 females leave the herd.
Has the herd reached its carrying capacity for this
ecosystem? How do you know?
O a. The herd has reached its carrying capacity
because the growth rate is negative.
Ob.The herd has reached its carrying
capacity because the growth rate
is positive.
O c. The herd has not reached its carrying capacity
because the growth rate is negative.
Od.The herd has not reached its carrying
capacity because the growth rate
is positive.
Answer:
Choice: (A) The herd has reached its carrying capacity because the growth rate is negative.
Explanation:
The herd has reached its carrying capacity because the growth rate is negative. Hence option a is correct.
What is ecosystem?Ecosystem is defined as a ecology's structural and functional unit where living things interact with one another and their surroundings. Healthy ecosystems maintain our soil, clean our air, control the climate, recycle nutrients, and give us food. They provide tools and raw ingredients for producing medicines and other goods. Major elements of many ecosystems include plants, animals, insects, microorganisms, rocks, soil, water, and sunlight.
Clumps can disperse in a region when there is an unequal distribution of resources like food, water, moisture, temperature, or other materials. More food supplies are available, finding a mate requires less migration for individuals, and organisms are better protected from predators.
Thus, the herd has reached its carrying capacity because the growth rate is negative. Hence option a is correct.

Which is denser, 50 mL of water or 500 mL of water?
Answer:
50mL
Explanation:
Density is inversely proportional to volume.
This implies that, for the same mass of water, the higher the volume, the less dense it is.
By comparison 500ml is greater than 50ml
Going by the above analysis, 50ml will be less dense than 500ml because it is smaller.

What factors might cause a kelp forest to disappear?
Answer: Natural Causes and Human Activities
Explanation:
The factors influencing kelp forest stability are diverse: kelp harvesting; grazing by fishes, sea urchins, and crustaceans; plant competition; storms; sedimentation; and pollution; global warming and the association with rising ocean temperatures.
Answer:

Explanation:
a large patch of warm water developed off the coast, creating a catalyst that has further changed this underwater environment. The persistent warmer sea temperatures stress the kelp forests to the point that growth and reproduction have slowed dramatically and caused damage to remaining fronds and tissue.

In the atmosphere, 50% of the air lies below an altitude of 89.0000655.
What do you mean by altitude of atmosphere?Exosphere. Located between about 700 and 10,000 kilometers (440 and 6,200 miles) above Earth's surface, the exosphere is the highest layer of Earth's atmosphere and, at its top, merges with the solar wind.
The commonly accepted end of earth's atmosphere falls within the thermosphere at 62 miles (100 kilometers) above the earth's surface. This commonly accepted boundary is called the Kármán Line.
The Stratosphere extends around 31 miles (50 km) down to anywhere from 4 to 12 miles (6 to 20 km) above the Earth's surface. This layer holds 19 percent of the atmosphere's gases but very little water vapor.

True or False: Enzymes have an optimal or ideal pH level?
Answer:
All enzymes have an ideal pH value, which is called optimal pH. Under the optimum pH conditions, each enzyme showed the maximum activity. For example, the optimum pH of an enzyme that works in the acidic environment of the human stomach is lower than that of an enzyme that works in a neutral environment of human blood. All enzymes have an optimum pH that they work best at. Its often neutral pH 7, but not always.
