Explanation:

Answer:

the 2nd answer

Explanation:

Given what we know about the way energy moves through the Earth, we can confirm that the vulture uses the hot air currents that result from this movement of energy to soar above the cliff.

The energy from the sun travels through the atmosphere, then into the soil where it is absorbed. The soil then radiates the heat back out into the atmosphere.

Given that hot air rises, this radiated heat causes the formation of hot air currents that the vulture then uses to glide upwards in a circular motion.

The vulture planes over the hot air currents with its wings at an angle to climb, it goes higher the further it wishes to travel given that once at the desired height, it glides downward towards its destination.

Jesus used the parables to lead the rabbis to a clearer understanding of God's plan.

In christian religion, Jesus used a method of teaching called parables to expatiate a most topics he handled. This was for the better understanding of God's plans.

The parables are defined as the short stories that demonstrates a moral lesson.

A typical example of a parable used by Jesus is the parable of the lost coin.

Here Jesus told a story of a woman that had ten coins and lost one of them. He said that the woman searched carefully until she finds it. she went ahead to call her neighbors to rejoice with her as she has found the lost coin.

In this parable, Jesus passed a clearer understanding of God's plan for a repented sinner. HE said that there is rejoicing in the presence of God over one sinner who repents.

It has an optimum pH of about 1.5. Trypsin's optimum pH is about 8.

Explanation:

This active trypsin acts with the other two principal digestive proteinases — pepsin and chymotrypsin — to break down dietary protein into peptides and amino acids. These amino acids are essential for muscle growth, hormone production and other important bodily functions.

Most of the time bacteria and archea reproduce by asexually .

Answer:

Most bacteria and archea reproduce asexually.

Explanation:

Answer:

because reproduction is nature gifted and it is the way to increase population but living cells are the cells which keeps us alive

Reproduction differs from the other five characteristics of living cells because of the ability to replicate for continued existence.

The characteristics of living things include -MR NIGER D(acronym to remember)

Now Reproduction differs from all the others because while others are processes that organisms need for existence or survival,Reproduction on the other hand is the reason for the continuation of existence of species(creation of a copy).  

Without reproduction,  Living organisms would go extinct and  would not be able to replicate themselves .

Answer:

Explanation:

Actually it was the experimental results of other scientists. The main stems of the theory was the indivisibility of small spheres (his image) that represented the elements he knew which reacted with other elements.

They seemed to give the same ratios in reactions (definite proportions) and multiple whole number ratios. Look up Lavoisier.

Explanation:

The Carbon Cycle

The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle.

Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.

Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.

Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.

Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But since the start of the Industrial Revolution about 150 years ago humans have burned so much fuel and released so much carbon dioxide into the air that global climate has risen over one degree Fahrenheit. The atmosphere has not held this much carbon for at least 420,000 years according to data from ice cores. The recent increase in amounts of greenhouse gases such as carbon dioxide is having a significant impact on the warming of our planet.

Carbon moves through our planet over longer time scales as well. For example, over millions of years weathering of rocks on land can add carbon to surface water which eventually runs off to the ocean. Over long time scales, carbon is removed from seawater when the shells and bones of marine animals and plankton collect on the sea floor. These shells and bones are made of limestone, which contains carbon. When they are deposited on the sea floor, carbon is stored from the rest of the carbon cycle for some amount of time. The amount of limestone deposited in the ocean depends somewhat on the amount of warm, tropical, shallow oceans on the planet because this is where prolific limestone-producing organisms such as corals live. The carbon can be released back to the atmosphere if the limestone melts or is metamorphosed in a subduction zone.

Answer: it is D : their motion increases

Explanation: because as heat is increased it causes the particles to gain more kinetic energy making them move faster thus increasing their motion and leading to more successful particle collision .

Fish take water into their mouth, passing the gills just behind its head on each side.

Answer:

Because velocity has magnitude and direction, speed is not a vector quantity since it only has magnitude

Your velocity is - 40m/s

Answer: D: The distribution of many organisms has already shifted as a result of warming.

Explanation: I just took the quiz on FLVS

The statement that supports the biological predictions as it relates to change in climate is : ( D ) The distribution of many organisms has already shifted as a result of warming

Climate change is the long term change in the Average weather conditions of a region, province or territory. Climate change is associated to global warming caused by the activities of man which affects the weather conditions of a given region in the long term.  

As the climate continues to change, many organisms begin to redistribute themselves to regions with favourable weather conditions, and this is the biological prediction/effect of climate change on the environment.

Hence we can conclude that The distribution of many organisms has already shifted as a result of warming  is the correct statement.

Plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

Vacuole is defined as a region of cytoplasm-free, membrane-lined, and liquid-filled space inside a cell. A membrane-bound cell organelle known as a vacuole.  The plant cell's equilibrium depends heavily on the vacuole. It participates in the regulation of cytoplasmic ions, pH, and the control of cell volume and turgor.

Animal cells lack a cell wall, whereas plant cells do. Animal cells lack chloroplasts while those of plants do. Animal cells have many little vacuoles, but plant cells only have one giant vacuole. Animal cells only have a cell membrane, but plant cells have both a cell wall and a cell membrane. Cell walls are used by plants to give the plant structure. Animal cells lack the organelles known as chloroplasts that are present in plant cells.

Thus, plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.
