Answer:
biology is the study of living things and other branches of pure science include physic and chemistry.
The introductory passage discusses the importance of being able to study anme in a pure culture instead of in the consortium that exists in nature. Many bacteria exist in biofilms in nature. Based on the information in the passage and in the chapter, is it possible to create a pure culture of a species that normally exists in biofilms?.
Yes, as a biofilm can include a single species and numerous species can have planktonic growth or reside there.
Plankton- Microalgae, sometimes referred to as phytoplankton, are comparable to photosynthetic organisms in that they have chlorophyll and need sunlight to survive and develop. The upper ocean, where sunlight may reach the water, is where the majority of phytoplankton floats since they are buoyant. The growth of plankton is known as Planktonic growth.
Biofilm- An extracellular polymeric material matrix surrounds an assembly of surface-associated microbial cells that is known as a biofilm. Van Leeuwenhoek is credited with discovering microbial biofilms because he discovered bacteria on tooth surfaces using his crude microscopes.

In a classic medical case study, it was written that phineas gage became emotionally labile and unable to restrain his impulsive behaviors after a severe head injury. While this account appears to have been vastly overstated, because of this story, these functions were associated with damage to which part of the brain?.
The functions are associated with damage to the frontal lobes part of the brain.
The frontal lobe is a part of the brain that controls important processes such as consciousness and communication, memory, attention, and others. In the brain, the frontal lobe is a part of the cerebral cortex. Injury to the prefrontal cortex in the frontal lobes of the brain can create dramatic personality changes in the absence of any obvious neurological impairments, as in Gage's case.
The prefrontal cortex's cardinal role is temporal organization of behavior, which is supported by the subordinate functions of short-term memory, motor attention, and inhibitory control. Gage's personality shift would be compatible with injury to the orbitofrontal cortex of his frontal lobe's ventral aspect, influencing his emotions.

Wild-type mice have brown fur. You have two strains of pure breeding mutant mice, both of which have white fur. When you cross the two strains with each other, all of the progeny have wild-type brown fur. What does this genetic complementation tell you?.
The phenotypic of coat color is influenced by several genes.
A gene have 2 alleles which decide the phenotype character. By crossing 2 mutant strain can result in the formation of wild type mice which have brown fur.
Gene- In every type of living creature, a gene is a highly precise sequence of nucleotide monomers that has the power to fully or partially regulate the expression of one or more features. Deoxyribonucleic acid (DNA) and, in the case of certain viruses, ribonucleic acid (RNA) polymers are used to create genes.
Phenotype- An observable characteristic is simply referred to as a "phenotype." Pheno, which has the same origin as the term "phenomenon," simply means "observe." It may therefore relate to anything ranging from a common attribute, like height or hair color, to the absence or presence of a disease. It is also an observable kind of an organism.

If a plant's stomata were temporarily inhibited from opening during the daytime, how would this affect the plant?
The plant would be unable to perform cellular respiration, and cells would become starved for energy.Carbon dioxide wanted for photosynthesis is acquired thru open plant stomata. At night time, whilst daylight is not to be had and photosynthesis isn't occurring, stomata near. This closure prevents water from escaping thru open pores.
Because flowers should change gases thru their stomata, final them prevents flowers from taking on carbon dioxide (CO2). Without CO2, flowers can't make carbohydrates, and flowers can most effective reap this vital molecule whilst stomata are open.
Plants lose the bulk in their water thru stomata. Thus, they near their stomata at night time to save you extra lack of water thru them. Stomata cannot be closed withinside the daytime, due to the fact the plant has to consumption carbon dioxide for the manner of photosynthesis.

According to the above formula, the percentage of genes that code for proteins is 97.95%.
Briefing:4380 genes are found in total.
4290 total proteins are encoded by the genes.
There are 5175720 base pairs overall.
Percentage of genes that code for proteins: Although there are 4380 genes overall, only 4290 of them code for proteins.
Total number of protein-coding genes divided by the total number of genes present gives the fraction of protein-coding genes (4290/4380), which equals 0.9795.
Percent fraction of genes encoding proteins

What impact does photosynthesis have on atmospheric carbon dioxide? Does it use or produce carbon dioxide?
Answer:
As photosynthetic organisms, plants take up atmospheric CO2, chemically reducing the carbon. This represents not only an acquisition of stored chemical energy for the plant but also provides the carbon skeletons for the organic molecules that make up a plant's structure. Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

the ganglion that supplies postganglionic parasympathetic innervation to the submandibular and sublingual salivary glands to increase their secretions is the
-The Submandibular Ganglion is the ganglion that provides postganglionic parasympathetic innervation to the submandibular and sublingual salivary glands to augment their secretions.
-The human autonomic nervous system includes the submandibular ganglion, often known as the submaxillary ganglion in earlier sources. It belongs to the head and neck's four parasympathetic ganglia. (The otic ganglion, pterygopalatine ganglion, and ciliary ganglion are the others.)
Where is it found?
Little and fusiform in shape, the submandibular ganglion is modest. It is located on the hyoglossus muscle, close to the posterior border of the mylohyoid muscle, over the deep part of the submandibular gland.
The ganglion "hangs" from the lower border of the lingual nerve by two nerve filaments (itself a branch of the mandibular nerve, CN V3). Two anterior and two posterior filaments support it from the lingual nerve. It receives a branch from the chorda tympani nerve, which runs in the sheath of the lingual nerve, through the posterior of these.
Fibers:
The submandibular ganglion, like other parasympathetic ganglia of the head and neck, serves as the synapse for parasympathetic nerve fibres as well as carrying other types of nerve fibre that do not synapse in the ganglion. The following is a list of the fibres carried in the ganglion:
sympathetic fibres from the face nerve and its branches, which travel through the external carotid plexus. In this ganglion, they do not synaptize.
Preganglionic parasympathetic fibres from the superior salivary nucleus of the Pons travel to this ganglion through the chorda tympani and lingual nerve.
salivary glands of the submandibular, sublingual, and oral mucosa are all served by postganglionic parasympathetic fibres. They act as these glands' secretomotors. After re-entering the lingual nerve, some postganglionic fibres travel to the sublingual gland.
