In sensory memory, auditory stimuli are to echoic memory as visual stimuli are to iconic memory.
What is Sensory memory ?After the initial stimulus has stopped, humans can still remember their impressions of sensory information thanks to sensory memory, which is a very short memory. It is frequently considered the first stage of memory, registering a huge amount of information about the surroundings for a very short time.
Examples of sensory memory :The information we get from our senses is stored in the sensory register and memory. Examples of sensory memory include smelling chicken noodle soup, feeling gum under a chair, and seeing a dog. These signals are sent to the brain by our eyes, noses, and nerves.

What structure appears to be underdeveloped or missing in the microtubules of the sperm flagellum affected by kartagener syndrome?
The Pairs of microtubules structure appears to be underdeveloped or missing in the microtubules of the sperm flagellum affected by kartagener syndrome.
Kartagener syndrome is a subset of PCD and consists of the triad of situs inversus, bronchiectasis, and chronic sinusitis.About 90% of the sperm's length is made up of the flagellum, which also comprises axoneme and peri-axoneme structures including the fibrous sheath, outer dense fibres, and the mitochondrial sheath. The flagellum is also where the sperm's ability to move is controlled.Microtubules determine the functional capacity of sperm since they are essential for organelle transport and cellular divisions during spermatogenesis and the sperm motility process. Axoneme and manchette, which are microtubule-based structures, are also essential for the development of the sperm head and tail.To learn more about sperm.

_____ dictate(s) the types and amounts of nutrients in food that will be transformed and reassembled into body structures and compounds.
Genes dictate the types and amounts of nutrients in food that will be transformed and reassembled into body structures and compounds.
Gene expression is induced by genes and thus alters the phenotype of an individual. In the converse single nucleotide polymorphisms taking place in a range of genes that are important in inflammation as well as the metabolism of lipids tend to alter the biological activity of important pathways of metabolism and mediators that influence nutrient ability to interact with them.
The genotype or allele set of genes is a unique combination of genes or genetic makeup of a particular individual. Thus genotype can be considered as a complete set of instructions that guides the body of a person to synthesize proteins which in turn pass information to make nutrients present in food to reassemble body structures.

In the __________, the reproductive cycle entails alternation of generations; a spore-producing generation alternates with one that produces eggs and sperm.
Answer:
In the ferns, the reproductive cycle entails alternation of generations; a spore-producing generation alternates with one that produces eggs and sperm.
Explanation:
A fern is a specific type of vascular plant which reproduces through spores rather than seeds or flowers. Ferns are plants with roots, stalks, and leaves, much like blooming plants. Unlike blooming plants, unfortunately, ferns lack flowers and seeds and rather than reproduce sexually by secreting microscopic spores or occasionally by vegetative means, as is the case with the walking fern.
In previously, many vascular plants that yield spores were loosely classed with ferns and referred to as "fern allies." Surprises concerning the connections between ferns and their companions have been revealed by recent genomic investigations. First, ferns and horsetails seem to have a lot in common. Horsetails are really now included in the fern family. Second, the flora club moss as well as quillworts, which are sometimes referred to as "fern allies," are in no way related to ferns.

Which division of the autonomic nervous system arouses the body and mobilizes its energy in stressful situations?
Answer:
The sympathetic nervous system (SNS) is the division of the autonomic nervous system arouses the body and mobilizes its energy in stressful situations.
Explanation:
The SNS is a part of the central nervous systems which are responsible for producing reflex cardiovascular system modifications as well as localised changes (such sweating in reaction to a rise in body temperature). The defence response, which is a broad rapid reaction, is produced when the SNS is fully engaged under stress. Large amounts of adrenaline are released from either the adrenal gland during this response, which is also characterized by a rise in cardiac function, heart rate, as well as skeletal muscle dilatation as well as pupillary dilation, bronchial dilatation, and piloerection. The ultimate result is to have the person ready for possible danger.

Biological variety is important to all our lives. Our world is home to a wide variety of life forms thanks to diversity. For each species to survive and find a niche in which to flourish, diversity is crucial. Without delving into the idea of evolution, diversity within our own species is evident in a number of observable traits, like height, and functional traits, such as the capacity for biotransformation. The pharmacogenomics discipline is emerging as a result of the latter source of variability. Unfortunately, biological diversity makes it difficult to examine the effects of treatments, even when the trial is planned and overseen beforehand.
