The deeper we breathe, the lower the percentage of (d) dead space is. Therefore, option d) dead space is the correct answer.

Dead space refers to the air that fills the respiratory system but does not participate in gas exchange with the blood. It includes the air that remains in the conducting airways of the lungs (such as the trachea, bronchi, and bronchioles) and does not reach the alveoli where gas exchange occurs.

When we take deep breaths, more air reaches the alveoli, which means that there is less air remaining in the conducting airways, and therefore less dead space. This results in a higher percentage of air that participates in gas exchange, leading to more efficient gas exchange and a higher oxygen uptake.

A clam uses gills for gas exchange, and its mantle cavity to take in oxygen.

Clams are bivalve mollusks that live in aquatic environments. Like other aquatic organisms, clams need to extract oxygen from the water in order to survive. Clams use their gills to extract dissolved oxygen from the water, which is then transported to the rest of the body for use in respiration. The gills of a clam are highly specialized structures that are adapted for gas exchange, with a large surface area and thin membranes that allow for the efficient diffusion of gases. In addition to their gills, clams also use their mantle cavity to take in oxygen. The mantle cavity is a space located between the clam's body and its outer shell. It is filled with water, which the clam pumps in and out of the cavity using specialized structures called siphons. As water flows over the mantle cavity, oxygen is extracted and transported to the rest of the body for use in respiration.

Nicotinic cholinergic receptors are a type of ionotropic receptor found in both the central and peripheral nervous systems.

Mechanism of action of nicotinic cholinergic receptors are:
1. Binding of neurotransmitter: The process begins when the neurotransmitter acetylcholine (ACh) is released into the synaptic cleft and binds to the nicotinic cholinergic receptors, which are a type of ligand-gated ion channel found on the post-synaptic membrane.
2. Ion channel opening: Upon binding of ACh, the receptor undergoes a conformational change that causes the ion channel to open. This opening allows the passage of specific ions, such as sodium (Na+) and potassium (K+), through the channel.
3. Ion flow and membrane depolarization: The flow of positively charged ions, particularly Na+, into the cell leads to a depolarization of the post-synaptic membrane. This depolarization is known as an excitatory postsynaptic potential (EPSP) and can result in the generation of an action potential if the threshold is reached.
4. Termination of signal: The signal is terminated when ACh is broken down by the enzyme acetylcholinesterase (AChE) and the ion channel returns to its closed state. The breakdown products of ACh are then taken up by the pre-synaptic neuron and recycled.

In summary, the mechanism of action of nicotinic cholinergic receptors involves binding of acetylcholine, opening of the ion channel, ion flow, and membrane depolarization, followed by termination of the signal.

Double fertilization is the process of fertilization of an egg by one sperm and an endosperm-forming cell by another sperm.

This unique event occurs in flowering plants and results in the formation of both a zygote and endosperm, which supports the development of the embryo within the seed.

During double fertilization, two sperm cells are delivered to the female gametophyte (embryo sac) within the ovule by the pollen tube. One sperm cell fertilizes the egg cell, resulting in the formation of a diploid zygote, which develops into the embryo of the plant.

The other sperm cell fuses with the central cell of the female gametophyte, which contains two polar nuclei, to form a triploid (3n) endosperm cell.

The endosperm is a nutrient-rich tissue that supports the growth and development of the embryo within the seed. It provides the developing plant with a source of carbohydrates, proteins, and lipids, and also plays a role in hormone production and storage.

The process of double fertilization is regulated by several genes and proteins that control the timing and specificity of sperm cell delivery to the female gametophyte.

When you are cold, your body's internal temperature drops, and to maintain homeostasis or a stable internal environment, your body activates a response called thermoregulation.

One of the first responses of thermoregulation is to constrict the blood vessels in your skin to reduce heat loss from the body's surface. Then, your body's muscles begin to contract involuntarily, generating heat through friction, which helps to raise your internal temperature. This process is called shivering.

Shivering helps the body maintain homeostasis by generating heat and raising the internal temperature to an optimal level. The heat generated during shivering is the body's way of compensating for the loss of heat due to the cold temperature. This process ensures that the body's internal temperature remains stable, which is necessary for proper cellular function and metabolism. Without shivering, the body would not be able to maintain its temperature, and this could lead to various complications such as hypothermia. Therefore, shivering is a crucial mechanism that helps the body to maintain homeostasis.
