Answer:

All plants need stomata on the surfaces of their leaves for photosynthesis. ... The stomata of water lilies are on the upper surface of their leaves, maximizing air exposure. Stomata on the underside of the leaves would be wasteful because water contact interferes with the exchange of carbon dioxide and oxygen.

mark me brainliestt :))

Answer:

Because the upper surface of the water lillies are not immersed in water.

Explanation:

Since the stomata is an opening for water to be excreted, the water lillies (which are usually found in water) need a surface which is not in contact with water so as the release the water as a metabolic waste. And since the lower surface of the water lilly's surface is immersed in water, there will be no point to excrete the water.

The energy of the sun heats the land unevenly, creating wind.

Earth, the third planet from the Sun, is the planet where all known life is found. Although the Solar System contains enormous amounts of water, only Earth is home to liquid surface water.

The ocean covers roughly 70.8% of Earth's surface, dwarfing the polar ice, lakes, and rivers. Earth's surface is made up of continents and islands for the remaining 29.2% of its total area.

Several slowly moving tectonic plates that make up the Earth's surface combine to create mountain ranges, volcanoes, and earthquakes. The magnetic field that forms the Earth's magnetosphere and diverts harmful solar winds is produced by the liquid outer core of the planet.

During the aerobic oxidation of carbohydrates, acetyl-CoA is produced through a series of metabolic reactions known as glycolysis and the citric acid cycle. During the aerobic oxidation of fatty acids, acetyl-CoA is produced through a process called beta-oxidation.

Pyruvate then enters the mitochondria, where it undergoes further processing to produce acetyl-CoA. This conversion occurs through a process called pyruvate decarboxylation, where pyruvate loses a carbon dioxide molecule and combines with coenzyme A (CoA) to form acetyl-CoA. Acetyl-CoA is a key molecule in energy metabolism and serves as a precursor for the citric acid cycle.

During the aerobic oxidation of fatty acids, acetyl-CoA is produced through a process called beta-oxidation. Fatty acids are broken down into two-carbon units, which then combine with CoA to form acetyl-CoA. This process occurs in the mitochondria, where fatty acids are sequentially cleaved into acetyl-CoA molecules. The acetyl-CoA molecules can enter the citric acid cycle to generate energy through oxidative phosphorylation.

Once acetyl-CoA is produced, it enters the citric acid cycle, also known as the Krebs cycle or TCA cycle. In this cycle, acetyl-CoA undergoes a series of enzymatic reactions, resulting in the production of ATP, NADH, and FADH2. These energy-rich molecules are then utilized in the electron transport chain to generate ATP through oxidative phosphorylation.

Natural selection occurs more prominently when there is competition for resources because competition creates selective pressures that drive adaptations and favor certain traits over others.

In any given environment, resources necessary for survival and reproduction, such as food, water, and shelter, are limited. As a result, individuals within a population must compete with one another to obtain these resources.

Competition leads to differential survival and reproductive success among individuals.

Those individuals with advantageous traits or variations that enable them to more effectively acquire and utilize resources have a higher likelihood of survival and producing offspring.

These advantageous traits can be physical characteristics, physiological adaptations, or behavioral strategies that provide a competitive edge.

Through natural selection, individuals possessing beneficial traits are more likely to pass on their genes to the next generation, while individuals with less favorable traits are at a disadvantage.

Over time, this process results in the accumulation of beneficial traits within the population, enhancing their overall fitness and adaptation to the specific environment.

Therefore, competition for resources acts as a driving force for natural selection by selecting for traits that enhance an individual's ability to secure limited resources, survive, and reproduce successfully.

When the DNA or RNA sequences are altered, the resultant amino acid can occasionally change as a result. A completely new sequence of amino acids may be produced as a result of how the ribosome interprets the mRNA sequence.

The amino acid sequence of the protein that the gene codes for can be altered by changes to the DNA sequence of that gene, a process known as mutation. A single DNA letter can change in a point mutation. They can be divided into three categories: Missense mutations alter a protein's single amino acid. DNA sequence modifications are known as mutations. Viral infection, mutagen exposure, or errors in DNA replication during cell division can all lead to mutations.

As a result, option C, which reads: "A change in the DNA sequence affects the RNA sequence, which occasionally results in a change in the resultant amino acid," is the right statement.

Most articles pass right through the atom, this means that most of the atom is an empty space.

An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.

Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.

As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

The polypeptide produced by translation of a processed eukaryotic mRNA by a eukaryotic cell or prokaryotic cell into which it has been introduced should have the same amino acid sequence because the genetic code is almost universal and the same codon chart can be used for both prokaryotic and eukaryotic organisms.

An area of DNA from a linear chromosome gets translated into a pre-mRNA in the nucleus. While remaining in the nucleus, this transcript must go through processing (splicing and inclusion of the 5' cap and poly-A tail).

In eukaryotes, one protein is represented by each bit of mRNA (or more than one protein in prokaryotes). Ribosomes employ the instructions provided by mRNA as a template during translation to attract and assemble the amino acids to produce the desired peptides/proteins.

80 barrels of oil is the net energy from this process.

What is net energy and how is it calculated?

Net energy refers to the amount of energy that is available for use after the energy required for extraction and refinement has been subtracted. In other words, it is the difference between the total energy available and the energy required to produce it.

Net energy can be calculated by subtracting the energy used in extracting, refining and/or transporting the energy source from the total energy produced. It is an important concept because it gives an indication of the overall efficiency of an energy source.

The net energy from this process is the amount of energy that is available for use after the energy required for extraction and refinement has been subtracted. To calculate this, we can use the following formula:

Net energy = Total energy available - Energy required for extraction and refinement

In this case, the total energy available is 100 barrels of oil. The energy required for extraction and refinement is 20 barrels of oil. So, the net energy from this process is:

Net energy = 100 - 20 = 80 barrels of oil

So, 80 barrels of oil is the net energy from this process.

While containers can be a convenient and practical way to grow plants in limited spaces, it is important to be aware of their limitations and choose plants and containers that are well-suited for each other.

The point that BEST supports the claim that containers used to hold growing plants can be "limiting" is option C, which states that some plants need to spread out. This is because containers have a limited amount of space, and if a plant is unable to spread out its roots, it may not be able to grow to its full potential or may even die. In contrast, ground soil allows plants to spread out their roots and grow to their full potential. Option A, which states that containers do not drain as well as ground soil, is also a factor that can limit plant growth. Poor drainage can lead to waterlogging and root rot, which can stunt or kill the plant. However, this limitation can be overcome by using containers with proper drainage holes and adding materials like sand or gravel to improve drainage. Option B, which states that some containers have been known to leak, is a minor limitation that can be addressed by using high-quality containers or fixing leaks as they occur.  Option D, which states that not all plants can be grown in containers, is also true, but it is not a limitation of containers themselves. Rather, it is a limitation of the plant's specific needs and requirements. Some plants require more space, nutrients, or sunlight than can be provided by a container, while others are well-suited for container gardening.
