Answer:

The correct order of protein production is:

c) 1,2,4,3

Ribosome: Protein synthesis begins in the ribosomes, which are located either in the cytoplasm or attached to the endoplasmic reticulum.

Endoplasmic Reticulum: After the initial stages of protein synthesis in the ribosomes, the newly synthesized protein is transported into the endoplasmic reticulum (ER) for further processing and modification.

Golgi Apparatus: The proteins synthesized in the ER undergo further processing and modifications in the Golgi apparatus. This includes sorting, packaging, and modifying the proteins to their final functional forms.

Secretory Vesicles: Once the proteins are properly processed and modified in the Golgi apparatus, they are packaged into secretory vesicles. These vesicles transport the proteins to their destination, such as the plasma membrane for secretion outside the cell.

Therefore, the correct order is 1, 2, 4, 3.

Answer:

The correct order of protein production is ribosome, endoplasmic reticulum, Golgi apparatus, and secretory vesicles. So the correct answer would be c) 1,2,4,3.

Many proteins destined for the endoplasmic reticulum, the Golgi apparatus, lysosomes, the plasma membrane, and secretion from the cell are synthesized on ribosomes that are bound to the membrane of the endoplasmic reticulum. The Golgi apparatus then distributes these proteins and lipids that it receives from the ER.

The factor that does not contribute to muscle fatigue associated with prolonged exercise is not explicitly mentioned in the question.

Muscle fatigue associated with prolonged exercise is a complex phenomenon influenced by various factors.

These factors can include metabolic changes, depletion of energy stores, accumulation of metabolic byproducts, impaired muscle contractility, and central nervous system fatigue.

However, the question does not specify which factor does not contribute to muscle fatigue.

To identify the factor that does not contribute to muscle fatigue, it would be necessary to consider factors that are known to play a role in muscle fatigue and exclude those that do not have a significant impact.

Some potential factors that might not contribute to muscle fatigue include psychological factors (e.g., motivation, attention), muscle fiber type distribution (as certain fiber types may be more resistant to fatigue), and genetic factors (individual variations in fatigue resistance).

However, without further information, it is not possible to determine the specific factor that does not contribute to muscle fatigue associated with prolonged exercise.

A cross between parents who have two different alleles for a single gene of interest is called a B) Monohybrid cross.

In genetics, a monohybrid cross is a breeding experiment between two individuals that differ in a single trait or gene. The individuals being crossed are known as the parental generation (P generation), and their offspring are called the first filial generation (F1 generation).

During a monohybrid cross, each parent passes one of their two alleles for the gene of interest to their offspring. The resulting F1 generation will all be heterozygous for the gene in question (having two different alleles), and they will display the dominant trait.

When the F1 generation individuals are crossed with each other, it is called an F1 cross, and the resulting offspring are called the second filial generation (F2 generation). The F2 generation will show a 3:1 phenotypic ratio of dominant to recessive traits.

A dihybrid cross involves the study of two genes that are inherited independently, while a trihybrid cross involves the study of three genes. A backcross involves crossing a hybrid offspring back to one of the parental generations.

True. Pruning, in the context of neurological development, refers to the process through which synapses that are not frequently used or activated are eliminated.

It is a crucial mechanism in brain development that occurs during childhood and adolescence.During early brain development, there is an overabundance of synapses, forming an intricate network. However, not all of these synapses are necessary for optimal brain functioning.

Through the process of pruning, the brain refines its neural connections by eliminating weak or unused synapses, leading to a more efficient and streamlined neural network.

Pruning is influenced by various factors, including neural activity, experience, and environmental stimuli. Synapses that are frequently activated and involved in important neural pathways are strengthened, while those that are not used or receive little input are gradually eliminated.

This process helps shape the developing brain and optimize its functionality, allowing for more efficient information processing and neural communication.True is the answer.

muscle contraction increases interstitial fluid pressure and compresses the blood vessels within the active muscle. As a consequence, blood flow is highest when muscles relax between successive muscle contractions.

Explanation:

Only 10% of the energy is transferred to the next level at each rung of the food chain, with the remaining 90% being lost as heat.

Energy is lost as metabolic heat when animals from one trophic level are ingested by species from the next level, hence energy diminishes as it goes up the food chain.

The remaining 90% is utilised for survival, growth, and reproduction and is wasted as heat to the environment. The base of every energy pyramid is the Sun, from which energy is transported to the first trophic level of producers. Species that devour other organisms, or consumers, receive their energy from producers.

The components of the cardiac conduction system are enclosed in the image.

The cardiac conduction system is a set of nerve-muscular elements through which the currents of the heart will pass to generate heartbeats. It starts from the SA node which is the heart's pacemaker since it will send the electrical impulses to generate the contraction. This will send the signals to the AV node, which will then send the signal through the purkinje fibers, which will divide into two branches that will end up covering the walls of the ventricles.

So then heartbeats are generated by the uniform distribution of these components.

Structure and Function

Explanation:

Answer: Cells are basic units of structure and function in living things. This means that cells form the parts or an organism and carry out all of the an organism's processes, or functions.

Mitochondria for energy production, lysosomes for digestion, and the endoplasmic reticulum and Golgi apparatus for storage and processing of nutrients.

Hibernation is a state of inactivity and metabolic depression in endothermic animals, characterized by low body temperature, slow breathing, and heart rate. During hibernation, animals reduce their metabolic rate and conserve energy to survive harsh conditions.

Several organelles within cells can play important roles in the processes of consuming, digesting, and storing food in preparation for hibernation. For instance, mitochondria help to break down food molecules through cellular respiration, releasing energy for the cell to use. Lysosomes contain enzymes that can break down macromolecules such as proteins and lipids into smaller components that can be utilized for energy or stored in other organelles such as vacuoles. The endoplasmic reticulum and Golgi apparatus can also help to modify and transport proteins and lipids for use in energy production or storage. Finally, lipid droplets within cells can store excess nutrients and provide energy reserves for hibernation.

The salt will move from the chamber on the left, where it has a high concentration, to the chamber on the right, where it has a low concentration. This is because the membrane is permeable to salt, meaning that it allows the salt to pass through.

The movement of the salt from a high concentration to a low concentration is called diffusion. Diffusion is the process by which particles move from an area of high concentration to an area of low concentration until they reach equilibrium. In this case, the salt will continue to move through the membrane from the left chamber to the right chamber until the concentration of salt is equal in both chambers.

Character displacement occurs in sympatry or allopatry.

In sympatry, character displacement refers to the evolutionary divergence of traits between two species that occupy the same geographical area. When two closely related species coexist in the same habitat, they often experience competition for limited resources.

To reduce competition, natural selection favors individuals with traits that differ from those of the other species, leading to the evolution of distinct characteristics. This process promotes niche differentiation and reduces competition, allowing the coexistence of species in the same area.

On the other hand, in allopatry, character displacement can also occur. Allopatric speciation refers to the formation of new species due to geographic isolation, where populations become separated by a physical barrier such as a mountain range or a body of water.

Over time, genetic and environmental factors can drive divergent selection in the separated populations, leading to the evolution of distinct traits.

If these populations come into contact again after a period of isolation, they may exhibit character displacement to further reduce competition and facilitate their coexistence.

ATP is converted to cyclic AMP with the aid of adenylyl cyclase. The hydrolysis of PIP2 is aided by phospholipase C. Consequently, all associations are accurate save for choice (D).

The majority of cell surface receptors activate internal target enzymes, which can be connected to receptors directly or indirectly through G proteins. The downstream signaling components that transmit and increase the signal started by ligand binding are these intracellular enzymes. The process known as intracellular signal transduction typically involves a series of events that convey signals from the cell surface to various intracellular destinations. These signaling pathways usually have transcription factors as their targets because they control how genes are expressed. Thus, the cell surface and the nucleus are connected by intracellular signaling pathways, which causes changes in gene expression in response to external stimuli. Glycogen phosphorylase, which catalyzes the conversion of glycogen to glucose-1-phosphate, is in turn phosphorylated and activated by phosphorylase kinase. Adenylyl cyclase converts ATP into cyclic AMP, which is then broken down by cAMP phosphodiesterase into AMP.
