Answer:

The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface.

The relationship between surface tension and cohesion is that Cohesion is directly proportional to surface tension.

Cohesion is the attraction of same molecules and surface tension occurs due to the attraction of molecules .

Therefore as the cohesion becomes high, surface tension becomes here.

We can say that the Cohesion is directly proportional to surface tension.

means As cohesion increases, surface tension increases.

Hence, the relationship between surface tension and cohesion is that Cohesion is directly proportional to surface tension.

Photosynthesis involves light-dependent reactions (electron transporter chain) and light-independent reactions (The Calvin cycle). Formula: 6CO₂ + 6H₂O + Light energy ⇒ C₆H₁₂O₆ + 6O₂. 1. Light reactions: Reactants:Light energy and water. Products: oxygen, ATP, and NADPH. 2. Electron transport chain: Reactants: NADP + Pi + ADP + 6H₂O. Products: O₂ + NADPH + H + ATP. 3. Dark reactions: Reactants: CO₂ + ribulose-1,5-bisphosphate + ATP + NADPH. Products: C₆H₁₂O₆. Summary below.

Photosynthesis involves two stages: light-dependent and light-independent reactions.

During these, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions.

Photosynthetic pigments are in charge of light absorption.

When sunlight reaches the pigments, electrons get excited and move along the electron transport chain, placed in the thylakoid membrane.

As electrons get excited, new electrons provided by water molecules replace the excited ones.

The final products are oxygen, ATP, and NADPH.

During the Calvin cycle, sugars or carbohydrates are synthesized.

When carbón dioxide, CO₂, enters the leaves through stomas, it diffuses to the chloroplast stroma.

Carbon atoms fixate, meaning that they incorporate into organic molecules. These molecules are used to produce 3-C sugars.

The whole process is impulsed by ATP and NADPH coming from light-dependent reactions.

Formula: 6CO₂ + 6H₂O + Light energy ⇒ C₆H₁₂O₆ + 6O₂

1. Light reactions:

reactants: Light energy and water

products: oxygen, ATP, and NADPH

summary of major events: light energy reaches the plant and exite electrons which move along the electron transporter chain in the thylakoid membrane. New electrons donated by water molecule replace the exited ones. Electrons move through photosystems while ATP and NADPH are produced.

2. Electron transport chain:

reactants: NADP + Pi + ADP + 6H₂O

products: O₂ + NADPH + H + ATP

summary of major events: Light energy is transformed into chemical energy (ATP and NADPH). Electrons are exited and move along the chain. Through photolysis, each water molecule provides two new unexited electrons and release two protons and one oxygen. Photoreduction of NADP occurs producing NADPH from exited electrons and protons released by water. Photophosphorilation of ATP occurs using ADP, Pi, and energy released by electrons as they move along the chain.

3. Dark reactions:

reactants: CO₂ + ribulose-1,5-bisphosphate + ATP + NADPH

products: C₆H₁₂O₆

summary or major events:

1. During the carbon fixation phase, a CO₂ molecule combinate with a ribulose-1,5-bisphosphate (5-C molecule) to form 6-C molecules, which will divide into two 3-phosphoglycerate molecules, 3-PGA (3-C molecules).

    CO₂ + ribulose-1,5-bisphosphate ⟶  6-C molecule ⟶ 2  3-PGA

2. During the reduction phase, ATP and NADPH are used to produce the sugar molecule glyceraldehyde-3-phosphate (G3P) from 3-PGA molecules.

NADPH donates its electrons to turn 3-PGA into glyceraldehyde 3-phosphate, G3P.

                  3-PGA + ATP + NADPH  ⟶ G3P + ADP + NADP⁺

3. During the regeneration phase,

• some glyceraldehyde 3-phosphate molecules leave the cycle and go to the cytosol to form glucose.

• Other G3P get recycled to regenérate the RuBP acceptor. This last reaction needs ATP and a series of other reactions.

When three CO₂ enters the cycle, 6 G3P are produced. One of them leaves the cycle, and the remaining five are recycled and generate three RuBP.

Explanation:

Nervous system has two divisions called central nervous system (CNS) and peripheral nervous system (PNS).

Nervous system is responsible for transmitting signals all over the body. It has two main parts: central nervous system (CNS) and peripheral nervous system (PNS). CNS include brain and spinal cord, and PNS includes the nerves branching off from the CNS and travelling all over the body. PNS is further divided into somatic nervous system and autonomic nervous system.

The primary role of PNS is to send messages from brain and spinal cord all over the body that helps in reacting to the stimuli.

Somatic system helps to carry signals to and from the CNS and controls voluntary movements. It comprises sensory and motor neurons. Sensory neurons helps to carry messages to the CNS and motor neurons are responsible for carrying messages out of the CNS.

Autonomic system helps to control involuntary functions like blood flow, etc. It has two sub-categories: sympathetic and parasympathetic systems. Systematic system responds to environmental threats while parasympathetic system is responsible for maintaining involuntary functions of the body.

No, the bacteria would not be expected to transcribe the gene. Introducing a eukaryotic promoter sequence into a prokaryotic cell would likely result in the bacteria being unable to recognize and properly initiate transcription from the modified promoter.

Prokaryotic and eukaryotic cells have different transcriptional machinery and regulatory mechanisms. Prokaryotic promoters have specific sequences recognized by prokaryotic RNA polymerase, which initiates transcription. Eukaryotic promoters, on the other hand, have distinct sequences recognized by RNA polymerase II. By replacing the prokaryotic promoter with a eukaryotic promoter in a prokaryotic cell, the cell's RNA polymerase would not be able to efficiently recognize and bind to the eukaryotic promoter. As a result, the gene would not be transcribed, and the bacteria would not express the gene. Therefore, introducing a eukaryotic promoter sequence in a prokaryotic cell would not lead to the transcription of the gene.

Therefore, it is unlikely that the bacteria would transcribe the gene. The absence of the appropriate transcription factors and machinery necessary for eukaryotic gene expression would hinder the recognition and initiation of transcription from the modified eukaryotic promoter sequence in the prokaryotic cell.

Before transcription can begin, RNA polymerase must find the location and direction of a gene on the chromosome based on its sequence. RNA polymerase ends transcription at a clear origin located at the end of a gene. It is common for amino acid biosynthetic genes to be transcriptionally activated in the presence of tRNAs as a result of the Stringent response, which requires charged sigma factor to bind RNA polymerase. An sRNA can inhibit mRNA translation by the ribosome through complementary base-pairing to the sequence in its target mRNA. During DNA replication, the sequence of the daughter strand being synthesized is determined by complementary base-pairing with the parent template strand, however, DNA polymerase can incorporate a base-pair that can result in a point mutation if it is not repaired. A bacteria can repair these mistakes and distinguish the original parent strand of DNA from the new daughter strand of DNA through methylation of certain nucleotides. In order to replicate their genomes, all SSRNA viruses must package an RNA-dependent RNA polymerase within their capsid.

RNA (Ribonucleic acid) is a single-stranded nucleic acid consisting of nucleotide monomers that performs essential roles in coding, decoding, regulation, and expression of genes.

The signal released from the synaptic vesicles is a neurotransmitter, and the type of signal it represents is chemical, option (b) is correct.

Neurons communicate with each other through synapses, which are specialized junctions between the presynaptic neuron (sending neuron) and the postsynaptic neuron (receiving neuron). When an action potential reaches the end of the presynaptic neuron, it triggers the release of chemical signals called neurotransmitters from synaptic vesicles into the synaptic cleft, which is the small gap between the two neurons.

These neurotransmitters diffuse across the synaptic cleft and bind to specific receptors on the postsynaptic neuron's membrane. This binding process initiates a series of biochemical events in the postsynaptic neuron, leading to the generation of electrical signals and the transmission of information from the presynaptic neuron to the postsynaptic neuron, option (b) is correct.

Answer:Each muscle in the body is made up of cells called muscle fibers. Muscle fibers are long, thin cells that can do something that other cells cannot do—they are able to get shorter.

Explanation:

IM not sure if this would help but their you go.

Muscle fibers are the cells that make up each muscle in the body. Muscle fibers are long, thin cells with the unique ability to shrink. Most cells cannot do this.

Cross-striations are the most noticeable histological characteristic of muscle fibres, which are massive multinucleated cells. Many myofibrils with tiny cylinders made of bundle of myofilaments can be found in the cytoplasm.

Myofilaments are made up of both thick filaments primarily made of myosin and thin filaments primarily made of actin. Due to their regular overlap, which is kept in register from across diameter of the muscle fiber, the thick and thin filaments create the cross-striations.

Thus, the cells that make up each muscle in the body are known as muscle fibres. Long, thin cells called muscle fibres have the unusual ability to contract and expand. Most cells are unable to achieve this.

Based on the experiment, you can determine the solute concentration by measuring the mass of the solute dissolved in a known volume of solvent and calculating the molarity. This can be done using a balance and volumetric flask or through titration methods.

To be more specific, first weigh the mass of the solute and dissolve it in a known volume of solvent, using a volumetric flask for accuracy. Then, calculate the molarity (moles per liter) by dividing the moles of solute (which can be determined by dividing the mass of the solute by its molar mass) by the volume of the solution in liters.

Alternatively, you can use a titration method, where a solution with a known concentration is added to the sample until the reaction is complete. By knowing the volume of titrant added and its concentration, you can determine the concentration of the solute in the sample.

When cells respond to an extracellular signal, they most often convert the information carried by this molecule from one form to another this process is called signal transduction.

Signal transduction is A fundamental process in molecular cell biology in which a signal from outside the cell is transformed into a functional change inside the cell.

During this process, the cell detects the extracellular signal and transforms it into a different form so that it can carry out the intended task. For instance, when a hormone binds to a receptor on the cell surface, cAMP molecules carry the signal into the cell.

The receptor protein undergoes some form of alteration when the signaling molecule binds to the receptor. The transduction process is started by this change. Usually, there are multiple steps in a pathway for signal transduction. The next molecule in the signal transduction pathway is altered by each relay molecule.
