As human travel increases, the number of introduced species likely
decreases.
increases
stays the same
is eliminated
Answer: The correct answer to the question is option B
INCREASES.
As human travel increases(As humans move from one place to another),the number of introduced species likely increases because as humans move from one place to another,they introduce new species of organisms to their new environment.
These non-native species grow in this new environment,becomes economically important and doesn't pose any harm to their new ecosystem unlike invasive species that poses a substantial harm.
The number of introduced species are likely to : ( B ) Increases
As Humans migrate from one place to another they introduce new species into their new environment naturally or artificially.
MigrationThe movement of humans or any type of organism comes with the introduction of new species because as they move they take along with them certain species that naturally do not belong to their new environment.
Hence we can conclude that As human travels The number of introduced species are likely to Increase.

PLEASE HELP ME I'LL MAKE YOU BRAINLIEST!!!!!!!!!! Lichens can best be described by which of the following? a) autotrophic organisms and fungi in a mutualistic relationship b) photosynthesizing fungi that can live in harsh environment conditions c) saprophytic fungi that secretes acids to grow on and colonize rocks d) two heterotrophic fungi species that thrive on nutrients from the air
Answer:
a) autotrophic organisms and fungi in a mutualistic relationship
Explanation:
A lichen "is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species".
It is cyanobacteria + fungi, so it has to be two separate groups, and both cannot be fungi.
Your question has been heard loud and clear.
answer is option C , lichens do colonize on rocks most of the time , this is because they really are saprophytic fungi , that secrete acids to melt and make the rocks suitable for growing on.
Water intoxication results from: A. Dilute body fluids B. Osmosis of water from ICF to ECF C. Decrease in water intake D. Decrease in the osmolarity of interstitial fluids E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids
Answer:
E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids
Explanation:
When there is excessive water intake into the body, it can lead to water intoxication. It occurs as result of a combination of dilute body fluids and decrease in the osmolarity of interstitial fluids.
When excess water is taken into the body, the extracellular fliuds become very dilute, this results in a decrease in osmolarity , therefore, water will then move into the intracellular fluid by osmosis in order to establish equilibrium.. This causes the cells to swell, and in the brain, this swelling will result in increase in pressure within the cranium. This increase in pressure leads to the symptoms found in water intoxication such as nausea, confusion, and fainting. If not treated, it can result in death.
From the given options;
A. Dilute body fluids is only a part of the cause
B. Osmosis of water from ICF to ECF does not result in water intoxication because in water intoxication, water moves into the ICF from ECF
C. Decrease in water intake is wrong because it is an increase in water intake that results in water intoxication
D. Decrease in the osmolarity of interstitial fluids is only one part of the cause of water intoxication
E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids is the correct option.

What process is similar in function to genetic engineering but different in the mechanism it uses? A. Replication in a bioreactor B. Cellular Respiration C. Breeding for specific traits D. Genetic Calculus
Option C. Breeding for specific traits is a similar process in function to genetic engineering but different in the mechanism it uses.
Genetic engineering refers to the process of using recombinant DNA methodologies to alter the genome of a particular organism and thus obtain the desired characteristics/traits in organisms derived from them. An example of genetic engineering is the use of recombinant DNA methodologies to develop Escherichia coli strains that generate human insulin.Moreover, selective breeding refers to the process aimed at developing organisms with desirable characteristics by choosing parents with these traits in order to cross them and produce offspring with these phenotypic traits.For example, wheat plants with better yields can be obtained by crossing between wheat varieties that exhibit desired phenotypic traits.In conclusion, Option C. Breeding for specific traits has a similar objective that genetic engineering but the mechanism to reach this objective is different.Learn more in:

The notion that the traits that help a species survive and reproduce are passed along more frequently than those that do not (i.e. differential reproduction and adaptation) is known as
Answer:
Natural selection
Explanation:
According to Darwin's theory, natural selection is the process by which individuals better adapted to their environments have more chances to survive and reproduce, and thereby their descendants will be better represented in the next generation. This mechanism exploits the existence of natural variation among members in the population which is used to select those individuals that are better adapted (i.e., with a higher adaptive fitness) for their environments. Natural selection is a key mechanism of evolution by which species change across time.

A water strider (which can walk on water)has legs that are coated with a hydrophobic substance. What might be the benefit? What would happen if the substance were hydrophilic?
Answer:
The water striders are the species, which are about half an inch in length and exhibiting a thin body with three legs set. The legs of water striders exhibit small hairs, which helps in repelling water and holding air. The water striders by repelling water stand on the surface of the water and the captivated air permit them to float and move readily.
The legs of water striders are coated with hydrophobic substances, which helps in repelling water and assists in keeping the terminals of the legs from getting coated with water. In case, if the legs of the species were coated with a hydrophilic substance, then water would be drawn up by the legs and would make the striders break through the surface and thus would have a tough time to walk on water.

What results if a broken chromosomal fragment becomes reattached as an extra segment to a sister or non-sister chromatid? A Duplication B Inversion C Polyploidy D Nondisjunction
Answer:
The correct answer is option A "Duplication".
Explanation:
Chromosomal duplication is defined as a type of rearrangement of genetic material at which extra copies of a DNA fragment are created. In this case if a broken chromosomal fragment becomes reattached, this fragment will represent an extra copy, and therefore the resultant genetic material is considered a chromosomal duplication.

What are emergent properties?
Answer:
Emerging properties may arise by transient interactions such as individual organisms building a population. Human interaction in populations leads to the emergence of language, poetry, musical composition, and art. When populations of different species interact, communities form. Many emergent properties are the result of interactions between species in communities.
Emergent properties are characteristics of a system that do not exist in any of its constituent parts individually but originate as a result of interactions between those parts.
What does the characters indicate at ?These characteristics are frequently intricate and challenging to forecast. Emergent characteristics are a crucial idea in several disciplines, including physics, chemistry, and biology.
Emergent qualities in biology can be observed in an organism's behaviour. For instance, a flock of birds' behaviour is an emergent characteristic of the individual birds that make up the flock.
The behaviour of the flock is a product of interactions among the individual birds and is not exhibited by any one individual bird. Similar to this, a school of fish's behaviour is an emergent characteristic of each fish.
Emergent features in chemistry can be observed in how molecules behave. An emergent attribute of a substance's individual molecules, for instance, is the substance's boiling point. The boiling point is not a property of any one molecule, but rather the outcome of interactions between the molecules.
Particle behaviour in physics exhibits emergent features. An emergent attribute of a material's individual particles, for instance, is the material's electrical conductivity.
The interactions between the individual particles produce the electrical conductivity, which is not a property of any one of the individual particles. As a result, emergent properties are characteristics of a system that develop.

Arrange the sentences in order to describe how oxygen from air is transported to the cells in the kidneys.
Answer:
The pulmonary veins carry oxygenated blood to the heart. Air enters the bronchioles in the lungs and reaches the alveoli. The capillaries join together to reach the arteries, transferring the oxygen. The oxygen-rich blood moves from the aorta and reaches the kidneys through a series of blood vessels.
Because he was well aware of the effect his theory of evolution would have on the public and on the Church of England, Darwin delayed publishing his work for several decades while he gathered additional evidence. After invoking selective breeding of domesticated species as evidence that groups of organisms are capable of change, he then proposed that natural populations can change as well. On which two lines of evidence did he base this proposal? a) Individuals within a population vary, yet island species around the world all appear to be related to each other.b) Organisms produce more offspring than can be supported by their environment, and adaptations to specific environments increase an organism's ability to survive and reproduce.c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.d) Some individuals leave more descendants than other individuals, but the individuals in a population are essentially identical to each other.e) Some individuals within a population have greater success in survival and reproduction than others, and favorable traits within a population will accumulate over generations.
Answer:
c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.
Explanation:
Darwin's theory was based on the evidence of natural selection and survival of the fittest.
Evidence of Darwin's theory were observed from the variation in the population which is supported by the environmental factor (natural selection) and these population than produce offspring, resulting in competition for survival within the population (survival for fittest).
Hence, the correct option is "c".
