The cell organelle that digests molecules, old organelles, and foreign substances is the Lysosome. The main constituent of lysosomes is hydrolase enzymes. The hydrolase enzymes of the lysosome, a membrane-bound vesicle, break down aged organelles and proteins into smaller molecules like amino acids.
Lysosomal hydrolytic enzymes are also helpful in destroying invading pathogens. Upon any bacterial/fungal/viral infection, the cell engulfs the pathogenic particle in a double membrane-bound vesicle called a phagosome, via phagocytosis. Phagosomes get fused with lysosome and hydrolytic enzymes help in the clearance of the pathogen.

In eukaryotic cells, the cell cycle is divided into two main phases in which the cell spends most of its time and metabolic energy. these two phases are?
Interphase and mitosis are the two main phases of the eukaryotic cell cycle where the cells spends most of time as well as as its metabolic energy.
The cell cycle involves the different stages which a cell goes through as it grows and divides in order to form new cells. Cell cycle requires metabolic energy as well as the availability of nutrients. In eukaryotes, this cycle is basically divided into interphase and mitosis.
The interphase can be subdivided into G1, S and G2 phases. The cell spends most of its time in this stage. It involves the duplication of the nuclear DNA which is present in the cell and during this stage the cell grows in size. No division of the cell takes place during interphase. This stage is succeeded by mitosis. This stage involves the division of the cell, that is, the single eukaryotic cell divides and results in the formation of two daughter cells which are genetically identical to their parent cell.

The fluid that enters vertebrate nephrons is called the filtrate. What is the source of the filtrate
the source of the filtrate is Loop of Henle.
The Henle loop is surrounded by tissue fluid with a high ion concentration. Osmosis causes water to move out of the descending limb. As a result of the more concentrated filtrate, ions move out of the loop in the thin ascending limb.
The nephron consists of a single long tubule and a ball of capillaries called the glomerulus. Using hydrostatic pressure, plasma is forced through the walls of the glomerulus, becoming filtrate as it crosses, and then collecting within Bowman's capsule. The fluid that enters vertebrate nephrons is called the filtrate.
Which part of the nephron is called the loop of Henle?A million nephrons are the filtering units of the human kidney, which is a complex and highly vascular organ. Each filters water and solutes from the blood that flows through it into the surrounding space and is the cavity between the cup's walls. The other part resembles a U-shaped loop that transports the filtered fluid deep into the medulla.
Functions of NephronThe primary function of the Nephron is to flush out waste products from the blood, which include solid waste and other excesses. This blood is transformed into urine through secretion and excretion.
The nephron, a basic structural unit of the kidney, is a microscopic structure composed of a renal corpuscle and a renal tubule.

Which synapse(s) are specifically responsible for the sensitization of the withdrawal response?
Answer choices:
Sensory neuron to facilitating interneuron
Sensory neuron to excitatory interneuron
Facilitating interneuron to excitatory interneuron
Sensory neuron to inhibitory interneuron
Sensory neuron to motor neuron
Excitatory interneuron to motor neuron
The correct option is (e) sensory neuron to motor neuron, responsible for the sensitization of the withdrawal response.
The central nervous system receives the excitation from a sensory neuron that has been stimulated by its nociceptors. Notably, these fibres deliver excitement to the sensory neuron's cell body, which is located in the spinal cord's dorsal root ganglia. The sensory neuron in the dorsal root ganglion transmits excitatory postsynaptic potentials (EPSPs) to motor neurons and interneurons after receiving the action potential from these fibres.
By releasing neurotransmitters into the central nervous system, the sensory neuron does this. Excited somatic motor neurons contract and depolarize the targeted muscles to complete the withdrawal reflex. The motor neuron, which leaves the spinal cord and enters the peripheral nervous system, is where this depolarization travels.
Therefore, sensory neuron to motor neuron is responsible for the sensitization of the withdrawal response.

Geologists have observed that a portion of Africa is breaking away from the main continent. This is happening because the African Plate is in the process of splitting up into two parts. Scientists have named the two new tectonic plates the Nubian Plate and Somalian Plate. Both of these plates are not only moving away from each other but also away from the Arabian Plate.
Based on this information, determine the type of boundaries these two new plates would share with each other and the Arabian Plate.
In divergent boundaries, plates separate from each other and new crust is created between them. The boundary these two new plates would share with each other and the Arabian Plate is the divergent boundary.
What are the three types of boundaries?I. Divergent
A new crust is created by the rising molten materials coming from the mantle.
Two plates separate, and a stream of hot material creates a new seabed between them. It occurs in an expansion of the sea bottom.
As old plates get separated, new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.
II. Convergent.
When two plates move forward to each other, they end up colliding and causing the deformation of one or both plates.
Three possible collisions might occur,
• Two oceanic plates might collide ⇒ subduction
• Two continental plates might collide ⇒ obduction
• Oceanic plate and continental plates collide ⇒ Subduction
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur on the continental plate.
In the exposed example, the African plate is splitting up into two parts, meaning these two parts are separating from each other. A new seabed is created between the Nubian Plate and Somalian Plate.
Since these plates are also separating from the Arabian Plate, we can also assume a new seabed is emerging between them.

When RNA polymerase synthesizes a new mRNA, interactions between the RNA polymerase, the DNA, and the RNA hold the complex together. When a hairpin loop forms in the nascent mRNA:
When a hairpin loop forms in the nascent mRNA: The hairpin will destabilize the interaction and possibly lead to transcriptional termination.
Transcription in prokaryotes like E. coli is terminated either by a rho-dependent process or a rho-independent process. Intrinsic termination is controlled by the specific sequences of RNA .
When the termination process starts, the transcribed mRNA forms a stable secondary structural hairpin loop, also known as a stem-loop. Several uracil nucleotides follow this RNA hairpin. The uracil and adenine connections are exceedingly weak. NusA, a protein attached to RNA polymerase, attaches to the stem-loop structure so firmly that it momentarily stalls the polymerase.
The polymerase is pausing at the same time that the poly-uracil sequence is being transcribed. The RNA-DNA duplex can unwind and separate from the RNA polymerase because the weak adenine-uracil interactions reduce the energy of destabilization for the RNA-DNA duplex. Overall, transcription is terminated by the modified RNA structure.
