Answer:

membranes are semipermeable so only let certain materials in and out; if there are carrier or channel proteins, then passive transport can occur otherwise active transport is required which requires energy.

Answer:

A catalyst is a chemical substance that affects the rate of a chemical reaction by altering the activation energy required for the reaction to proceed. This process is called catalysis. A catalyst is not consumed by the reaction and it may participate in multiple reactions at a time.

SIGHT.

If one is experiencing Na channels deactivating the plasma membrane,the sense that is being activated is SIGHT,

this is because in the red blood cell,the light induced isomerization of the moiety retinal rhodoesin produce activated opsin which goes ahead to activate the signal transducing G-protein transducin,this it does by catalyzing exchange of GTP (Guanosine triphosphate) for bound GDP(guanosine diphosphate) on the subunit.

This GTP in turn activates the level of CGMP (Cyclic guanosine monophosphate) phosphodiesterase and it further acts to lower the level of CGMP.

Upon this reduction,it leads to the closing of CGMP-gated Na+ channels and hyperpolarization of the membrane.

50 people because the widow's peak is dominant. Those who don't have a widow's peak do not have the gene.

If the gene for the hair pattern "widow's peak" is dominant, it means that individuals with at least one dominant allele will express the trait. We would expect 50 people to be heterozygous (Ww) for the widow's peak trait.

Heterozygous refers to a genetic condition in which an individual possesses two different alleles for a specific gene. Alleles are alternate forms of a gene that can code for different variations of a particular trait. In a heterozygous individual, one allele is dominant and the other is recessive.

The dominant allele is expressed in the phenotype, meaning it determines the physical appearance or characteristic, while the recessive allele remains hidden and does not show in the individual's observable traits. The notation for a heterozygous trait is typically represented by two different letters, one for each allele (e.g., Aa).

Assuming that "W" represents the dominant allele for widow's peak, and "w" represents the recessive allele.

Given that 50 people in the population have a widow's peak (homozygous dominant, WW), we can deduce that the other 50 people must have the genotype for heterozygous (Ww) to express the trait.

Answer:

fishes

Explanation:

A progenitor feature found in early boney fish served as the basis for the development of the vertebrate lung.

The lung of modern vertebrates evolved from a structure that was present in the ancestors of early boney fish.

Lungs in vertebrates originated as extra air-breathing organs in primordial fishes and were ventilated by buccal pumping when they first appeared. In more modern fishes, the organ formerly known as the lungs has been replaced with the hydrostatic swimbladder. This fundamental kind of unicameral lungs and the buccal pumping ventilation observed in these lungs can also be found in more modern amphibians.

A forest ecosystem is more stable than a potato field.

Explanation:

The forest ecosystem is a natural one and all the elements are balanced, they are managed by the nature itself.

The forest ecosystem is a natural one, and all the components are in harmony since nature herself manages the ecosystem.

Thus, A forest ecosystem, or simply a forest, is a community of plants, animals, microorganisms, and other species that interact with the chemical and physical elements of their environment.

The species in a forest ecosystem are depending on one another in order to survive, and they can be roughly categorized as producers, consumers, and decomposers based on their ecological roles.

The boreal forest that surrounds the Earth in northern latitudes is an example of a vast forest ecosystem. A forest ecosystem can also be as small as a microsite on a tree limb where mosses, insects, and microscopic species coexist.

Thus, The forest ecosystem is a natural one, and all the components are in harmony since nature herself manages the ecosystem.

The scientific process is important when learning about diseases because it allows to obtain reliable and valid knowledge about the different existing diseases, it helps in solving problems correctly and it is the best tool to nullify arbitrary opinions regarding a diagnosis or treatment, taking into account each of its stages.

Explanation:

The scientific method is a process through which relationships between facts are established to arrive at the verification of something. Through this step by step in which facts are discarded and added, the answers to findings are based. It is through the information generated by the research that it is possible to associate and / or integrate a set of symptoms and signs with a probable nosological diagnosis. Similarly, the selection of treatment and even the prognosis of patients depend on the information obtained from a population of subjects who share attributes; they depend, in a word, on research. Bearing in mind the scientific process, scientific thinking develops with practice, and for this it is necessary that there be constant reflection on the problems, have guides for the interpretation of medical reading, develop research protocols, learn to collect and analyze data about diseases.

Scientific is very important in order to obtain information about the disease.

The scientific process is important when learning about diseases because it provides information about various aspects of diseases as well as provides solution about cure of the disease.

This scientific process or method can be used for obtaining information about the causes of disease, its causing agents and cure for the disease so we can conclude that scientific is very important in order to obtain information about the disease.
