Answer:

In general, monocots do not undergo secondary growth. If they do increase in girth (like palm trees and yucca plants), it does not result in the development of a secondary xylem and phloem, since monocots don't have vascular cambium. An increase in girth without secondary growth is referred to as anomalous thickening.

Many disorders are due to the inability of an individual to break down a particular chemical. A person who has a disease called phenylketonuria (PKU).

Which prevents them from breaking down the amino acid phenylalanine, this is one example of a person who is unable to break down a chemical in their body.

Giving a person the right enzymes can help treat these diseases. Chemicals in our bodies are broken down by enzymes, which act as biological catalysts.

Therefore, if a person is deficient in the right enzyme, that person can be cured by giving them that enzyme. Let's discuss the remaining options.

Antigens are dangerous foreign substances that have gotten inside the body. The genetic material is stored on chromosomes, which are found inside the nucleus.

Organelles are cellular structures, such as the mitochondria, nucleus, and endoplasmic reticulum, that have particular roles.

Thermoregulation:  D. Muscles under the skin make body hair stand on end.

Thermoregulation means maintaining constant body temperature of 37 degrees Celsius. Through a number of physical mechanisms, the human body keeps its temperature at roughly 98.6°F (37°C). Shivering to increase body temperature, sweating to decrease it, and constricting or relaxing blood vessels to change blood flow are a few examples. An individual may overheat and develop hyperthermia if they are unable to control their body temperature. The inverse is also true: Hypothermia will result if the core temperature drops below a safe level. Both ailments have the potential to be fatal.

The skin's hairs aid in controlling body temperature. Each hair's erector muscle makes them stand straight when they're cold. Insulates by trapping a layer of warm air close to the skin.

The statement "single cells cannot exist independently" is correct.

Cells are the basic unit of life and are essential for the functioning of living organisms. Single cells, such as bacteria and protozoa, can exist independently, but they are still dependent on the external environment for survival. For example, they need a source of energy, such as sunlight or organic matter, and a source of nutrients, such as minerals and vitamins. Single cells also have a limited set of functions and cannot perform all the functions required for survival on their own.

However, multicellular organisms, such as animals and plants, are made up of many cells that work together to perform all the functions required for survival. These cells are specialized to perform specific functions, such as digestion, movement, and reproduction. They also communicate and coordinate with each other to ensure the survival of the organism as a whole. Therefore, it is correct to say that single cells cannot exist independently.

Answer:

Cell wall, chloroplast, vacuole. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Explanation:

The main difference between plant cells and animal cells are cell wall and chloroplast , whereas for the vacuole plants have a vacuole called vescile which is not the same as the vacuole in plant cells.

Vacuoles are very large as they are needed to store water and they mostly contain water and sugars . On the other hand, vesicles are small and contain water, nutrients, enzymes, wastes, solution of water or food etc. This is the key difference between vacuoles and vesicles. hope it helps :)

The trp operon is a group of genes for the biosynthesis of the amino acid tryptophan in bacteria.

Thus, the trp operon consists of five structural genes (trpE, trpD, trpC, trpB, and trpA), an operator region, and a promoter region. When tryptophan levels are high, the repressor protein binds to the operator region, thereby, blocking the transcription of the structural genes.

When tryptophan levels are low, the repressor protein is not able to bind the operator region, and RNA polymerase, which can initiate transcription of the structural genes. The trp operon is an negative feedback regulation of gene expression in bacteria as its presence inhibits the transcription of the genes responsible for its synthesis.

Answer: Heat transfer

Explanation:

Hot material such as hot air or liquid is more dense that cool material so it will rise. As it does so the cool material will sink towards the source of heat that is making the hotter materials hot and get heated as well which will enable it to rise and the whole cycle repeats.

This type of heat transfer is called Convection and it is very important to processes occurring on earth from basic things such as how water is heated in a kettle to how rainclouds are formed in the atmosphere.

Based on the pH scale, Milk has a pH of 6 while Tomato juice has a pH of 4, milk is 100 times less acidic than tomato juice.

The correct answer is B.

The pH scale is logarithmic, meaning that each number on the scale represents a tenfold difference in acidity or basicity.

A pH of 4 is 10 times more acidic than a pH of 5, and 100 times more acidic than a pH of 6. Therefore, to compare the acidity of milk (pH 6) and tomato juice (pH 4), we can say:

Milk (pH 6) is 100 times less acidic than tomato juice (pH 4).

Answer:

a. It's a carrier protein doing facillitated diffusion

Explanation:

Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.

The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.

Complete question:

Receptors trigger one of two effector pathways resulting in changes in neuronal activity. These changes will, ultimately, effect gene expression. Which effector pathway is characterized by ion flux through transmitter-activated channels resulting in an altered membrane potential and neuronal activity?

A.  Slow effector pathways

B.  Modulated effector pathways

C.  Rapid effector pathways

D.  NMDA glutamate receptor pathways

Answer:

D.  NMDA glutamate receptor pathways

Explanation:

The NMDA glutamatergic receptor is a cationic channel receptor modulated by a ligand that allows the transport of Na+, K+, and Ca2+. Under certain situations, it exhibits particular permeability to Ca2+. The receptor has different regions that are susceptible to modulation by endogenous and exogenous agents. The receptor can be found at most excitatory synapses, where it responds to the neurotransmitter glutamate. During synapsis, the presynaptic membrane releases L-glutamate, which is received by NMDA glutamatergic receptor. The receptor plays a regulatory role because activates signaling cascades that depend on calcium.

These receptors are involved in normal synaptic transmission, in a diverse physiological phenomenon, and might be responsible for neurodegenerative processes.

The NMDA glutamergic receptor is characterized by ion flux through transmitter-activated channels resulting in membrane potential.

Transmitter-activated channels are channels through cell membranes which are activated by binding of transmitters.

An example of a transmitter-activated channels is the NMDA glutamergic receptor.

The NMDA glutamergic receptor is a ligand-gated cationic channel that allows calcium, potassium and sodium ions through it.

The step 3 exercise tells us that a hybrid male individual and a hybrid female individual (F1) mate with each other and have offspring. In this context, by the term hybrid, we know that the exercise refers to the organisms' genotype having two different alleles for the fur color (in this case we can use B for black fur color, and b for white, for example), what would be Bb. We can complete then the Punnet squares as follows:

Here we can see the information that will be useful to do the other square, which is like the following:

We can compare these two probabilities by saying that for 3 organisms with black fur, there would be 1 with white fur, having a ratio of 3:1. This also can be approached by saying that the predicted percentage usually reflects the simulated numbers and the simulated percentages, since although there can be a lower or higher ratio, it is still near that value: 3:1.
