In the larval stage, females in most species of bees can develop into a queen or a worker, depending on the food they received. If only 0.01% of females develop as a queen, what percentage are coerced into becoming worker bees by the queen limiting their food?
If only 0.01% of females develop as a queen, 85 percent are coerced into becoming worker bees by the queen limiting their food.
All female larvae younger than three days can develop into a queen, however, the youngest larvae, those younger than one day, create larger, more robust queens. Younger larvae have a greater chance of receiving the best nutrients and developing to their full potential because they receive more royal jelly throughout their development when they are chosen to become queens.
On the other hand, on the third day, worker-destined larvae switch to a "worker jelly" diet. Royal jelly, pollen, and nectar are all components of worker jelly. While larvae fed just worker jelly grow into sterile workers, those fed only royal jelly mature into fertile queens.

An infant has learned to use a baby spoon and now picks up a regular metal spoon. Her initial attempt to grasp the spoon is clumsy and reflects the process of assimilation. She makes subtle adjustments to her grasping movements, which reflects the process of accommodation.
Learning to use a spoon is just as vital as learning to self-feed with your fingers. It's a developmental milestone that children reach shortly after finishing the first year and master by the age of two. Children could prefer using their fingers because they receive safe-feeling input through their skin, muscles, and joints. With a spoon, the mouth, lips, and tongue are largely used for feedback.

A number of chemical treatments cause microtubules to fall apart. Colchicine is one such drug. What would happen if a dividing cell was treated with colchicine?.
A number of chemical treatments cause microtubules to fall apart. Colchicine is one such drug. If a dividing cell was treated with colchicine, chromosomes would not separate.
Microtubules can be defined as structures that are actively present in the cytoskeleton of eukaryotic cells.
The microtubules are a major part of the cell division process as they are involved in the formation of the mitotic spindle. This mitotic spindle ensures that the sister chromosomes are separated at the time of cell division. As a result of this segregation, there is an equal division of chromosomes among the daughter cells.
Hence, if a dividing cell was treated with colchicine, then the microtubules will fall apart. As a result of this, the mitotic spindle will not form and chromosomes will not separate.

Calculate the solute potential of a 0.2M NaCl solution at 30°C. Find your answers in bars.
The solute potential of a 0.2M NaCl solution of 30⁰C and the bars Ѱs = - 10.07172 bars.
Given:i = 2,
C = 0.2 (mol/L).,
R = 0.0831 L·bars/mol·K,
Formula for solute potential
Ѱs = -iCRT
The formula Ѱs = - iCRT can be used to determine solute potential. As long as there are solutes in solution, the solute potential is negative. The number of ions that the solute dissociates into is indicated by the letter ‘i’ the solute potential decreases when the solution can split into more ions.
To find T,
The Kelvin unit of measurement, "T," is equal to 273.15 plus the temperature in degrees Celsius.
T = 30°+273.15
= 303.15.
It can be expressed as either 0.00831 (liters times megapascals over moles times Kelvin) or 0.0831 (liters times bars over moles times Kelvin).
Ѱs = - (2) (0.2) (0.0831) (303.15)
Ѱs = - 10.07172 Bars
With an increase in solute concentration, solute potential (s) drops; this results in a decrease in total water potential (s).

A mediated immune response that is effective against extracellular antigens, such as bacteria, viruses, and toxins when they are outside the cell is called antibody.
What is an antibody?
An antibody is a protein-based element of the immune system that travels through the blood and detects and destroys foreign entities like bacteria and viruses. Antibodies remain in circulation in the blood after exposure to an antigen, acting as a defense against additional exposures to that antigen.
A component of the host cell's defense is the antibody. It is produced by a particular kind of white blood cell known as a B cell. Two light chains and two heavy chains make up the antibody's structure, and at its very tip is a hypervariable area that enables the antibody to produce a variety of antibodies that will react to all of the antigens that may attack the body.

Proteins in the plasma membrane are often the target of medicines. discuss why you think this is the case.
Targeting the proteins in the plasma membrane does not require the drug taken up into the cell.
The cell membrane or plasma membrane is the outer covering of the cell. It is selectively permeable which does not allow every molecule to pass through it. It only allows some selective organic molecules to enter or exit through it. It, therefore, does not allow medications to pass thorough it or alter its chemical composition. Rather the medications target the proteins there to allow their functioning.
Plasma membrane proteins transmit the signals into the cell and catalyze reactions. The chemical composition of a drug is altered by the plasma membrane and a more acceptable form is produced to facilitate absorption by the desired organ. It also performs the distribution of drugs to various organs to produce the desired therapeutic effect.
Because not all drugs or medications are natural or organic molecules, they can't enter the cell. Therefore, any medication or drug targets the proteins in the plasma membrane.

William is developing the model shown below to illustrate the process of photosynthesis. He plans to use the model to explain how photosynthesis transforms both energy and matter.
To revise the model, William wants to use color to identify the reactants of photosynthesis. Which labels should he color? Select all that apply.
William can use Green shades for chloroplasts & Chlorophyll, Blue for water, Yellow for Light and Brown for Gases.
With the aid of carbon dioxide and water as reactants, photosynthesis is the process that transforms light energy into chemical energy stored in the form of sugars. Carbon is removed from the atmosphere via photosynthesis, transported to the geosphere, and then absorbed by plants. Four steps/processes can be used to objectively divide the total photosynthetic process:
The taking up of light. Chlorophylls connected to proteins in the thylakoids of chloroplasts absorb light as the first stage in photosynthesis. Transfer of electrons, production of ATP, and carbon fixation. A reaction that is endothermic is photosynthesis. This indicates that without energy, it cannot happen (from the Sun). Chlorophyll, a green pigment found in leaves, absorbs the needed light.

Explain why the heart rate and finger pulse change during a valsalva maneuver. Include in your explanation how changes in arterial blood pressure, peripheral resistance, and autonomic nervous activity bring about these responses.
The heart rate and finger pulse change during a valsalva maneuver due to changes in arterial blood pressure, peripheral resistance, and autonomic nervous activity.
Arterial blood pressure changes during a valsalva maneuver due to the increased pressure in the chest from the contraction of the abdominal muscles. This increased pressure squeezes the heart and reduces the amount of blood that returns to it. The heart then has to work harder to pump blood, which increases the heart rate.
Peripheral resistance changes during a valsalva maneuver due to the increased pressure in the chest and abdominal muscles. This increased pressure squeezes the blood vessels and reduces blood flow. The body then has to work harder to pump blood, which increases the peripheral resistance.
Autonomic nervous activity changes during a valsalva maneuver due to the increased pressure in the chest and abdominal muscles. This increased pressure activates the sympathetic nervous system, which increases heart rate and blood pressure.
