The correct match of the protein type with its description is: (1) Membrane Channel - protein with a pore that admits some molecules but not others; (2) Digestive enzyme - protein that has a binding site that fits a particular molecule; (3) Muscle protein - protein consisting of contractile fibers; (4) Structural Protein - protein with a cable-like structure

Proteins are the organic biomolecules composed of amino acids as the monomers. These monomers are joined together by the peptide bonds. The proteins are very essential for the body as they perform a variety of functions like structural, enzymatic, signaling, transport, etc.

Digestive enzymes are the proteinaceous molecules that aid in enhancing the rate of various chemical reactions involved in the process of digestion. The example of digestive enzymes are: amylases, lipases, proteases, etc.

Complete question:

Receptors trigger one of two effector pathways resulting in changes in neuronal activity. These changes will, ultimately, effect gene expression. Which effector pathway is characterized by ion flux through transmitter-activated channels resulting in an altered membrane potential and neuronal activity?

A.  Slow effector pathways

B.  Modulated effector pathways

C.  Rapid effector pathways

D.  NMDA glutamate receptor pathways

Answer:

D.  NMDA glutamate receptor pathways

Explanation:

The NMDA glutamatergic receptor is a cationic channel receptor modulated by a ligand that allows the transport of Na+, K+, and Ca2+. Under certain situations, it exhibits particular permeability to Ca2+. The receptor has different regions that are susceptible to modulation by endogenous and exogenous agents. The receptor can be found at most excitatory synapses, where it responds to the neurotransmitter glutamate. During synapsis, the presynaptic membrane releases L-glutamate, which is received by NMDA glutamatergic receptor. The receptor plays a regulatory role because activates signaling cascades that depend on calcium.

These receptors are involved in normal synaptic transmission, in a diverse physiological phenomenon, and might be responsible for neurodegenerative processes.

The NMDA glutamergic receptor is characterized by ion flux through transmitter-activated channels resulting in membrane potential.

Transmitter-activated channels are channels through cell membranes which are activated by binding of transmitters.

An example of a transmitter-activated channels is the NMDA glutamergic receptor.

The NMDA glutamergic receptor is a ligand-gated cationic channel that allows calcium, potassium and sodium ions through it.

Answer:

A) A) The gene encoding miR-5 is in a region of chromatin with hypoacetylation.  

D) The gene encoding miR-5 in a region of heterochromatin.

B) D) the absence of the UCD protein due to miR-5 inhibiting translation of the UCD mRNA transcript

Explanation:

MicroRNAs (miRNAs) are small regulatory RNA sequences (approximately 20-24 nucleotides in length) that regulate gene expression by RNA interference (RNAi) mechanisms. These sequences (miRNAs) bind by base complementarity to messenger RNAs and thus inhibit protein translation and/or trigger mRNA degradation. In this case, miR-5 binds to the 3’UTR of the mRNA transcript of the UCD gene, thereby inhibiting/slowing protein UCD synthesis. The UCD protein is an allosteric regulator that binds and activates the expression of the p101 protein, thereby the miR-5 RNAi pathway also indirectly decreases the expression of the p101 gene. Moreover, hypoacetylation is an epigenetic mark generally associated with gene silencing (heterochromatin is a transcriptionally inactive state of chromatin).

The main skeletal features used to construct a cladogram include the presence or absence of specific bones/structures, bone shape/structure, dental characteristics, skeletal adaptations, and skull morphology.

Cladograms are phylogenetic trees that illustrate the evolutionary relationships between different organisms. When constructing a cladogram, various skeletal features can be used as characters to determine the branching patterns and common ancestry among organisms. Here are some main skeletal features used in cladistic analysis:

Presence or absence of specific bones or structures: The presence or absence of certain skeletal elements, such as wings or limbs, can provide insights into evolutionary relationships.

Bone shape and structure: Comparing the shapes, sizes, and structures of bones can help identify shared characteristics and infer common ancestry.

Dental characteristics: The structure and arrangement of teeth, including the type and number of teeth, can provide information about evolutionary relationships and dietary adaptations.

Skeletal adaptations: Features like the presence of a notochord, presence of a bony skeleton, or modifications for specialized locomotion (e.g., wings, fins, limbs) can be used to infer evolutionary relationships.

Skull morphology: Examination of the skull, including the shape of the cranium, presence and structure of specific cranial bones, and jaw structure, can help determine evolutionary relationships and functional adaptations.

By analyzing these skeletal features and comparing them across different organisms, cladistic analysis aims to identify shared derived characteristics (synapomorphies) that indicate common ancestry and to construct a branching pattern that represents the evolutionary relationships between the organisms being studied.

Recessive traits are coded by two copies of recessive alleles. The inheritance pattern is autosomal recessive. Yellow pod color and cystic fibrosis are inherited by autosomal recessive genes.

Recessive traits are those coded by recessive alleles and can only be expressed in individuals whose genotyope is homozygous recessive. This is, individuals who only carry recessive alleles for that trait.

Alleles (dominant and recessive) are variants of the same gene.

The gene codes for a characteristic, and the allele codes for one variant of the characteristic, which is the trait.

So recessive traits are coded by the recessive variant of a gene.

Autosomal recessive inheritance characterizes by the expression of the recessive trait. Two copies of these alleles are needed to express the recessive phenotype and no dominant alleles.

For instance,

Mitochondria make use of the Electron Transport Chain to build an electrochemical gradient by pumping protons across the internal mitochondrial membrane, while chloroplast chemiosmosis refers to the use of the free energy difference to phosphorylate ADP in order to generate ATP drives by the ATP Synthase.

The Electron Transport Chain is a key process in the mechanism of oxidative phosphorylation, which represents the third step of cellular respiration. During this process, electrons move through a series of carriers, and the energy it is used to pump protons across the inner mitochondrial membrane.

Subsequently, the electrochemical potential generate is used to generate ATP by chemiosmosis, which uses the fee energy and a series of protein complexes located in the mitochondrial membrane.

Based on the given information, the top consumers in the food chain would be the coyote and the red fox.

A food chain is a representation of the feeding relationships between different organisms in an ecosystem. It shows how energy and nutrients are transferred from one organism to another through consumption.

In a food chain, each organism occupies a trophic level, which represents its position in the chain based on its source of food. At the base of the food chain are primary producers, such as plants or algae, which produce their own food through photosynthesis. Herbivores, which feed on primary producers, occupy the next trophic level.

These animals are positioned at the highest trophic level in the food chain, indicating that they consume other organisms but are not themselves preyed upon by any other organisms in the given food chain.

Therefore, the correct selections from the organisms provided are the coyote and the red fox.
