Answer:
Surface properties have less to do with virus lifespan than does the type of virus. Viruses tend to remain viable for longer on non-porous materials than on porous ones. Viruses tend to remain viable longer on surfaces with low moisture content.
Explanation:
The surface properties in the lifespan of a flu virus are associated with the fact that viruses tend to remain viable for longer on non-porous materials than on porous ones.
Influenza (flu) viruses are contagious viral infections capable of affecting the airways of the lungs.It has been shown that flu viruses survive on human tissues for only 15 min because of their surface properties.Moreover, it has been shown that these viruses cannot survive on non-porous metal/plastic surfaces by more than 9 hours.In conclusion, the surface properties in the lifespan of a flu virus are associated with the fact that viruses tend to remain viable for longer on non-porous materials than on porous ones.

are worm neurons alive????
Answer:
Yes
Explanation:
In the inner-world perspective of the simulation, the worm is absolutely alive as it is obeying the laws of physics as presented by the simulation.
Answer: Yes
Explanation:
Growing to just one millimeter in length, these simple creatures have only 302 neurons, or nerve cells, in their bodies, a tiny fraction of the 80 billion or so neurons in the human brain. ... They found the circuit has "command neurons" that release serotonin to increase movement in the worms.
What transport substances to where they need to go
in the cell
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion
Explanation:
Transport proteins generally perform two types of transport: “facilitated diffusion,” where a transport protein simply creates an opening for a substance to diffuse down its concentration gradient; and “active transport,” where the cell expends energy in order to move a substance against its concentration gradient
If fossils of fish and sea shells are found in an area that is now desert, we might assu
that:
• Fish could breathe air at one time in their history.
• Sea shells could live on land millions of years ago.
• The area in which the fossils were found was once covered with water.
• None of the above.
Answer:
The area once contained water.
Explanation:
Fish do not have the anatomical structures necessary for breathing on land. Even if they did, they would likely desiccate in the arid environment of the desert. The same reasoning applies to seashells. As a result, the environment must have been different in order to support the needs of these creatures. Since the Earth's continents are continuously shifting due to plate tectonics, and the Earth's climate changes over time, it would be reasonable to say that the desert was once a body of water that could support marine life.

(d) Predict the most likely cause of the F2 ratio obtained by the students in the second analysis between parental flies that are true-breeding for gray bodies and long wings and flies that are true-breeding for ebony bodies and curly wings. Provide reasoning to justify your prediction
Based on ransom crossing, the genotypic and phenotypic ratio of offspring depends on whether each trait is dominant or recessive.
What determines the phenotype of offspring in a cross between parents?The phenotype of the offspring or filial generation of a cross is determined by the genotype of the parents and the nature of the allele of the genes in the parents, whether they are recessive or dominant.
When two true-breeding species of organisms are crossed, the phenotype of the offspring will be determined by the dominant trait.
For examples, if parental flies that are true-breeding for gray bodies and long wings and flies that are true-breeding for ebony bodies and curly wings are crosed, the genotypic ratio and the phenotypic ratio will be as follows:
GGLL × ggll = GgLl, GgLl, GgLl, GgLl
Phenotypic ratio = 1 Genotypic ratio = 1Where:
G = gray body is dominantg = ebony body is recessive L = long wings is dominantl = curly wings is recessiveTherefore, the genotypic and phenotypic ratio of offspring depends on whether each trait is dominant or recessive.

When a strand of dna was replicated, one base was left out. Why would this be more damaging than if the base was only changed?.
Leaving out a base during the process of replication is quite dangerous because this may result in a non-functional protein.
Incomplete proteinWhen a base is left out during replication and the mRNA generated is used to synthesize protein, the codons will be incomplete and will result in an incomplete or non-functional protein.
Codons are in a base of 3. Thus, leaving out a base means that an entire codon has been rendered useless. This also means that the amino acids of the protein synthesized will be incomplete.
This either results in a totally different or non-functional protein.

What two characteristics of life are described in the following statement? “A human begins life as a single cell, whereas an adult is made up of trillions of cells.”
Answer:
Cellular Organization and Growth & Development
Explanation:
The fact that a human is initially defined by "a single cell" and later defined as "trillions of cells" demonstrates that all living things are made up of an organization of cells as cells are the building blocks of all life. The contrast of the single cell with the trillions shows the growth and development from the beginning of life to the fully developed form of an adult human.

1. Explain the concept of "natural selection" using your moths as an example (please use the data you collected to support your answer).
Answer: Natural selection can be seen in peppered moths, according to Tutt. In the gloomy bush, the brilliant moth's camouflage had worn off. Because dark moths live longer, they have more time to breed in a dark forest. All living creatures are impacted by natural selection. The peppered moth's evolution is an evolutionary example of moth population-directed color change as a result of industrial pollution.
The natural selection is based on the suitability and adaptation of an organism with that environment.
What is natural selection?Natural selection is the process in which populations of living organisms are selected by natural forces. Nature selects organisms that have traits better suited to the environment than others.
