pulls up the water in the stem.
B. Water made by photosynthesis is stored in a vacuole
for later use in the leaf.
O c. Water flows between the xylem and ground tissue and
in and out of a stoma.
O D. Water flows in through a stoma to xylem in the leaf,
where it is used for photosynthesis.
SUBMIT
Water exits through a stoma by transpiration and helps pull up the water in the stem.
Option (a) is correct.
In the top section of the diagram, water exits through a stoma by a process called transpiration. Stomata are small openings on the surface of leaves that regulate gas exchange, including the release of water vapor. As water evaporates through the stomata, it creates a negative pressure gradient, known as transpiration pull, that helps in the upward movement of water in the stem.
Transpiration pull occurs due to the cohesion and adhesion properties of water molecules. Water molecules are cohesive, meaning they stick together, and they also adhere to the walls of the xylem vessels in the stem.
As water evaporates from the leaf, it pulls on the column of water in the xylem, causing a continuous flow of water from the roots to the leaves. This process is known as the transpiration stream and is responsible for the upward movement of water and nutrients in plants.
So, option A is the correct answer as it accurately describes the movement of water through transpiration and its role in pulling up water in the stem.

In what way do symptoms of disease differ from signs of disease?
A symptom is subjective, that is, apparent only to the patient (for example back pain or fatigue), a sign is any objective evidence of a disease that can be observed by others (for example a skin rash or lump).
Signs and symptoms are the visible, audible, or felt symptoms of a disease, injury, or condition. Symptoms are the patient's stated subjective experiences, whereas signs are objective and externally detectable. A sign might, for instance, be a higher or lower-than-normal fever, a rise or fall in blood pressure, or an abnormality that appears on a scan. An individual experiences a symptom when they sense anything abnormal in their body, such as a fever, a headache, or various types of pain.
Indicators are distinct from symptoms that are really felt. A indication of a condition is something that can be seen by another person or found during a test or operation performed by a doctor. For instance, during a physical, elevated blood pressure may be discovered as a marker even though there are no known symptoms. A symptom is anything that a person can experience and report, such as a headache or exhaustion. There may be overlap between symptoms and signs, as in the case of a bloody nose that both the person experiencing it and others may see as unusual (sign).

If enzymes E1, E2 and E3 are not associated together anymore, what will happen to the activity of PDH, isocitrate dehydrogenase, or a-ketoglutarate dehydrogenase?
If enzymes E1, E2 and E3 are not associated together anymore, there will be no activity in PDH, isocitrate dehydrogenase, or a-ketoglutarate dehydrogenase
In multi-enzyme complexes like the pyruvate dehydrogenase complex (PDH), the isocitrate dehydrogenase (IDH), and the alpha-ketoglutarate dehydrogenase (-KGDH) complex, substrate channelling can take place. Due to the physical association of the enzymes in these complexes, the intermediate products can be transferred from one enzyme to another without dispersing into the bulk solution.
Therefore, substrate channelling cannot take place and the activity of the complex will diminish if the enzymes E1, E2, and E3 are no longer linked together. It is crucial to remember that despite the slower rates, each enzyme in these complexes can still catalyze its specific reaction independently, and the intermediate products will diffuse into the bulk solution to be processed by the following enzyme.

if photosynthesis and respiration are almost symmetrical processes, how is energy lost in the process of converting sugar back into atp?
Photosynthesis and respiration are almost symmetrical processes, as both involve the conversion of energy between different forms. During photosynthesis, light energy is converted into chemical energy in the form of glucose, while during respiration, glucose is broken down to release energy that is used to produce ATP.
However, while the overall process of converting sugar back into ATP is exergonic (releases energy), there is still some energy lost in the form of heat. This is because not all of the energy released during the breakdown of glucose can be captured and converted into ATP.
Some of the energy is lost during the conversion process itself, as well as through various metabolic reactions that occur throughout the cell. Therefore, while photosynthesis and respiration are symmetrical in terms of the overall conversion of energy, there is still some energy loss during the process of converting sugar back into ATP.

heterozygous geneotype codes for a blending of phenotypes in _______ inheritance.
Heterozygous genotype codes for a blending of phenotypes in incomplete dominance inheritance. In incomplete dominance, one allele is not completely dominant over the other. This results in a phenotype that is a blend of the two alleles.
For example, if the dominant allele codes for a red flower and the recessive allele codes for a white flower, then the heterozygous geneotype would result in a pink flower. In incomplete dominance, the phenotype of the offspring is neither the same as the phenotype of the dominant parent nor the phenotype of the recessive parent. Instead, the offspring's phenotype is a blend of the two. The genotype of the offspring is heterozygous, meaning it contains two different alleles, one from each parent.
Incomplete dominance is different from codominance, which results in two phenotypes present in the same individual. An example of codominance is the red and white stripes of a zebra, in which both the red and white alleles are expressed. Inheritance patterns such as incomplete dominance, codominance, and multiple alleles all have one thing in common - they result in the expression of more than one phenotype from the same gene.

Which of these states of hemoglobin represents the high affinity binding O2 conformation of the hemoglobin? a) T state b) B state c) D state d) R state.
The high affinity binding O2 conformation of the hemoglobin is represented by the R (relaxed) state. Here option D is the correct answer.
The R state of hemoglobin is characterized by a more open structure, which allows oxygen to bind more easily to the heme groups of the four subunits of hemoglobin. In the R state, the heme groups are positioned in such a way that they can bind to oxygen molecules. This state is favored in the presence of high oxygen concentration, such as in the lungs, where hemoglobin picks up oxygen to transport it to the body's tissues.
In contrast, the T (tense) state of hemoglobin represents the low-affinity binding O2 conformation of hemoglobin. In the T state, hemoglobin has a more compact structure, making it harder for oxygen to bind to the heme groups. This state is favored in the presence of low oxygen concentration, such as in the tissues, where hemoglobin releases oxygen for cellular respiration.
The transition between the T and R states is controlled by various factors, including the concentration of oxygen, carbon dioxide, and pH. The regulation of hemoglobin's affinity for oxygen is essential for maintaining adequate oxygen delivery to the body's tissues and organs.

Why do ions need membrane transport proteins to help them cross the plasma membrane?
a. Because they are not proteins
b. Because of their charge
c. Because they are not charged
d. Because of their size
Ions need membrane transport proteins to help them cross the
plasma membrane B. because of their charge.
The plasma membrane is a selectively permeable barrier that separates the cell's internal environment from the external environment. The membrane is composed of a lipid bilayer that is impermeable to most ions and polar molecules.
Ions are charged particles that cannot freely pass through the hydrophobic interior of the lipid bilayer. Therefore, they require specialized transport proteins to facilitate their movement across the membrane. These transport proteins allow ions to pass through the membrane via a variety of mechanisms, such as channels, carriers, or pumps.
The transport proteins are specific to the type of ion they transport, and they often require energy in the form of ATP to move the ions against their concentration gradient. Without these transport proteins, the movement of ions across the membrane would be severely limited, which could have significant effects on cellular function and homeostasis.
In summary, membrane transport proteins are necessary for ions to cross the plasma membrane due to their charge, as the hydrophobic interior of the lipid bilayer is impermeable to charged particles.

in a photosystem, the ____ complex captures light energy and passes it to the ____ center where electrons are transferred out of the system.
In a photosystem, the light-harvesting complex captures light energy and passes it to the reaction center where electrons are transferred out of the system.
Photosystems are structures located in the thylakoid membranes of plants' chloroplasts, which are responsible for the initial stages of photosynthesis. Photosystems consist of pigments such as chlorophyll, as well as associated proteins that facilitate light energy capture and electron transfer.
During photosynthesis, there are two main photosystems, Photosystem I (PSI) and Photosystem II (PSII). These photosystems work together to convert light energy into chemical energy through a series of redox reactions.
Light energy is first absorbed by the pigments in the light-harvesting complex, which then transfers the energy to the reaction center where it is used to excite an electron to a higher energy state. This excited electron is then passed through a series of electron carriers, releasing energy as it goes, until it eventually reaches a terminal electron acceptor where it is used to reduce another molecule (usually NADP+) to NADPH.
This process is called electron transfer, and it is a critical step in the production of ATP and NADPH during photosynthesis.

There are only about 40 tRNA molecules that represent 40 anticodons but there are 61 codons that each specify the addition of a specific amino acid.
How is that possible?It is possible that different tRNA molecules with different anticodons can recognize and bind to the same codon. As a result, a single tRNA molecule can be used to read multiple codons that all specify the same amino acid. The wobbling or degeneracy of the genetic code makes it possible for multiple codons to encode the same amino acid, allowing for fewer tRNAs to be utilized.
To provide an example, there are 4 codons that specify the amino acid alanine (GCN, GCU, GCC, and GCA), but only two tRNA molecules with the anticodon 5′-CGA-3′ are needed to bind all four codons because the third position of the codon can wobble to bind the G or the A base.
