Determination is the term that refers to the regulatory events that establish a specific pattern of gene activity and developmental fate for a given cell.

Cell determination is a feature of a cell by which it decides its fate. Cell determination leads a cell to follow a specific pathway in order for it to turn into a specialized cell. The process of cell determination occurs through inductive signaling.

The process of cell determination occurs in totipotent embryonic stem cells. Cell determination recognizes the portions in an embryonic or pre-mature cell that need to be expressed, hence turning the cell into a specialized one.

The process of cell determination leads to cell differentiation. By cell determination, a cell determines which gene regulatory changes need to be done for it. After cell differentiation, the cell changes into a certain type performing a certain specialized function.

Neurotransmitters are the effector molecules in intercellular signal transduction in neurons. They transmit signals across synapses by binding to receptors on postsynaptic neurons or target cells, initiating further biochemical events.

The effector molecule at the synapse of an intercellular signal transduction process in a neuron is a neurotransmitter. Neurotransmitters are chemical messengers that transmit signals across the synapse, the junction between two neurons or between a neuron and its target cell (such as a muscle or gland).

When an action potential reaches the presynaptic neuron's terminal, it triggers the release of neurotransmitter molecules into the synaptic cleft. These neurotransmitters then bind to specific receptors on the postsynaptic neuron or target cell, initiating a series of biochemical events that propagate the signal.

The specific type of neurotransmitter released and the receptors present on the postsynaptic neuron or target cell determine the nature and outcome of the signal transmission. Examples of neurotransmitters include acetylcholine, dopamine, serotonin, and gamma-aminobutyric acid (GABA).

Overall, neurotransmitters serve as the effector molecules in intercellular signal transduction in neurons, playing a critical role in the transmission of electrical impulses and communication between neurons in the nervous system.

A weak, subthreshold stimulus will result in a small depolarization at the receiving end of the neuron.a weak, subthreshold stimulus will primarily result in a small depolarization at the receiving end of the neuron, but it will not initiate an action potential or trigger neurotransmitter release.

When a neuron receives a stimulus, it can either be strong enough to generate an action potential or be subthreshold, meaning it does not reach the threshold necessary to trigger an action potential.

In the case of a weak, subthreshold stimulus, the neuron will undergo a small depolarization at the receiving end, known as the dendrites and cell body.

The dendrites and cell body of a neuron contain numerous ion channels, including ligand-gated channels and voltage-gated channels.

These channels regulate the movement of ions, such as sodium (Na+), potassium (K+), and chloride (Cl-), which are crucial for generating electrical signals in the neuron.

When a subthreshold stimulus is received, it causes a small influx of positive ions, typically sodium ions, into the neuron through ligand-gated channels.

This influx of positive charge results in a slight depolarization of the neuron's membrane potential.

However, the depolarization does not reach the threshold required to initiate an action potential.

As a result, the subthreshold stimulus is unable to propagate as an action potential along the axon of the neuron.

Instead, the small depolarization may weaken as it travels along the neuron's dendrites and cell body.

This weak signal may not be sufficient to trigger the release of neurotransmitters at the axon terminal, which is necessary for communication between neurons.

The time it takes for a body to float after drowning can vary depending on several factors, such as the individual's body composition, clothing, water conditions, and other variables. It is challenging to provide an exact timeframe as it can be influenced by numerous factors and is highly unpredictable.

When a person drowns, their body initially sinks due to the negative buoyancy caused by the air trapped in the lungs. Over time, as the body undergoes decomposition and gases are produced, it can eventually become buoyant and rise to the water's surface. This process is known as "bloating."

Bloating usually occurs within 1 to 4 days after a person's death, but it can take longer in some cases. However, it's important to note that there is significant variability, and the timeframe can be influenced by environmental conditions, temperature, and other factors.

It's crucial to rely on professional search and rescue personnel, medical examiners, or forensic experts for accurate information and investigations related to drowning incidents.

The time it takes for a body to float after drowning can vary depending on several factors, including the body's composition, water temperature, and surrounding conditions.

The process of a body floating after drowning is attributed to the accumulation of gases produced during decomposition. When a person drowns, water fills their lungs, preventing them from floating immediately. Over time, bacteria in the body begin to break down organic matter, releasing gases such as methane and carbon dioxide. These gases gradually build up within the body, causing it to become buoyant and eventually rise to the water's surface.

The time it takes for a body to float can be influenced by multiple factors. One significant factor is the body's composition, as factors like body fat percentage and muscle density can affect the rate of decomposition and gas production. Additionally, water temperature plays a role, as warmer water accelerates the decomposition process and the subsequent release of gases. Other variables such as water depth, currents, and the presence of obstacles can also affect how quickly a body resurfaces. Therefore, while the general timeframe for a body to float after drowning is around 1-2 days, it is important to remember that individual circumstances and environmental conditions can cause significant variations.

Explanation:

Answer:

c

Explanation:

Answer:

Passive transport moves molecules and ions from a higher concentration to a lower concentration without any energy while active transport does the same thing only it uses energy. Osmosis deals with the net movement of solvent molecules through a membrane with a higher solute concentration. Osmosis and active transport both work together, while osmosis does its own movement the active transport moves the dissolved solutes across a membrane against a concentration gradient.

Active transport and passive transport are almost the same they function the same only one doesn't require energy while the other one does. Hence why active transport and osmosis work well together it's because of the energy that helps transport dissolved solutes.

Gibberellins are plant hormones that help to regulate various plant processes such as seed germination, stem growth, and flowering.

They are mainly transported in plants from the roots to the tips of the leaves by the xylem.Gibberellins, like other hormones, are manufactured in certain parts of the plant, such as the tips of the leaves, and then transported to other parts of the plant where they are required. To move throughout the plant, hormones must enter the xylem, which is the long-distance water and nutrient transport system of the plant. The hormone molecules can then enter the plant's vascular system, where they are transported to the other parts of the plant, such as the roots. Gibberellins are transported from the roots to the tips of the leaves through the xylem vessels.The ability of gibberellins to promote stem elongation is based on the fact that they stimulate the growth of the cells in the stem, causing the stem to lengthen. Gibberellins can be produced naturally by the plant or can be applied as a foliar spray or as a seed treatment to enhance plant growth and development.
