why Should A Potometer be Allowed to stand before starting the Experiment
It is crucial to avoid air bubbles in the assembled potometer. The plant stem must be cut underwater to prevent airlocks forming in the xylem. All fittings must be tight so that the only way the apparatus can lose water is by the plant transpiring.

Have a nice day!!Pepsin and Trypsin are enzymes. At what pH do they have the highest rate of reaction?
Answer:
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.

What similarities, if any, do you think exist between a human’s reproductive cycle and the life cycle of a fern? What differences, if any, can you think of?
Answer:
The similarity between ferns and humans is that both go through meiosis and mitosis. But ferns are different because they have multicellular, free-living haploid and diploid forms. In humans, the haploid stage exists in the form of single cells—sperm and eggs. Only the diploid stage that begins with a zygote grows mitotically to form a multicellular, free-living human.
Explanation:
Humans and ferns are similar as both of these organisms fertilize to reproduce while differs in the haploid form of life which is present in the ferns and the male and female reproductive parts present in humans.
What is the life cycle of a fern?
The life cycle of fern includes the diploid fern which gives rise to the haploid spores that grows and form a gametophyte plant in which both the male and female reproductive systems are present. The male gamete undergoes fertilization with the female gamete to form a diploid spore (seed) which gives rise to the new fern plant.
Human’s reproductive cycle include diploid animals and the male and female genders which can be distinguished clearly. The male gamete-sperm fertilizes with the female gamete-egg to form the diploid zygote that gives rise to a new human.

A) Sea levels will fall, causing migration of 50% of the world's human population.
B) Carbon dioxide levels and temperature changes are direct related in the studies.
C) Studies show that atmospheric carbon dioxide has increased over the past 150 years.
D) The distribution of many organisms has already shifted as a result of warming.
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
What is climate change ?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.

How is reproduction different than the other five characteristics of living cells?
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)
Movement RespirationNutritionIrritabilityGrowthExcretionReproductionDeathNow 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 .

The image shows a vulture soaring over a rocky cliff. The arrows model the different ways energy moves between the sun, atmosphere, and geosphere.
Match each type of energy transfer to the arrows shown in the image. Describe how energy transfer helps the vulture soar above this rocky cliff.
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.

Will mark brainliest :D
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.
