Explanation:
Understanding the molecular basis of life helped in developing many technologies some used to further discover the cell, and others used to diagnose diseases or create organs or perform surgeries. Choose one technology and describe it briefly indicating its uses. 2. In what ways might genetically engineered organisms pose a threat to the health and safety of human populations
Answer:
1- The CRISPR-Cas system
2- Genetically modified organisms raise concerns associated with allergic reactions, horizontal gene transfer and outcrossing
Explanation:
The CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-Cas (CRISPR-associated) technology is widely used in medicine and research. The CRISPR-Cas is a versatile RNA-programable genome editing system capable of introducing genetic modifications at target DNA sequences. This technology is based on the natural bacterial immune system that cleaves bacteriophages and plasmid DNA sequences. Moreover, Genetically Modified Organisms (GMO) have historically raised three major concerns on human health: 1-the allergenicity of GMO foods, 2-the ability that GMOs might have to insert genes through horizontal transfer and 3-outcrossing between GMOs and (genetically) unmodified crops, which are further consumed as non-GM foods.
The diagram below shows the structure of an animal cell.
Which number label represents the cell membrane?
A)1
B)2 C)4 D)6
Answer:
1
Explanation:
1 number label represents the cell membrane, materials moving into and out of the cell are controlled by the cell membrane, hence option A is correct.
What is a cell membrane?A durable barrier between two aqueous compartments is formed by the phospholipid bilayer, which is the membrane's basic structural component.
They have receptors and channels that let particular molecules like ions, nutrients, wastes, and metabolic products that mediate cellular and extracellular activities pass between organelles and between the membrane.
Therefore, biological membranes are semipermeable and serve three main purposes, they prevent toxic substances from entering the cell, hence option A is correct.

vocalizations during courtship. These visual and auditory signals may make then more likely to attract predators and be killed.
Evaluate the statements to find the best description for the evolution of male coloration and vocalization in birds.
-0,)
A)
Colorful and vocal birds may be eaten by predators with greater frequency,
so this is a poor adaptation.
B)
Colorful and vocal male birds may attract the most mates and pass on
their genes. This is an adaptive trait.
Colorful and vocal birds mimic their drab counterparts when predators are
nearby, so predators are just as likely to eat any member of the population.
O
D)
Colorful and vocal birds will only mate with colorful and vocal females,
meaning these groups will become a different species from their drab
counterparts.
Answer:
A)
Colorful and vocal birds may be eaten by predators with greater frequency,
so this is a poor adaptation.
Explanation:
Colourful and vocal male birds may attract the most mates and pass on their genes. Therefore, option (B) is correct.
What is evolution?Evolution is the process of gradual change in the characteristics of a population over time through the mechanisms of natural selection, genetic drift, and gene flow, resulting in the emergence of new species.
While it is true that colourful and vocal birds may be more visible to predators and more likely to be eaten, the fact that they have evolved to develop these traits indicates that the benefits of attracting mates and passing on their genes outweigh the risks of predation. Male birds use their coloration and vocalizations to attract females and demonstrate their genetic fitness, and females select mates based on these traits. Therefore, over time, the male birds with the most attractive traits will be more successful at reproducing, leading to the evolution and persistence of these traits in the population.

What effect did the human population have on Easter Island? How did they change the island's natural cycling of matter and energy?
Answer:
The population history of the island remains highly controversial. In addition to internal conflict, the population crash has been attributed to “ecocide,” in which the Island's resources were exhausted by its inhabitants, reducing its ability to support human life.
Explanation:
Europeans was known to discovered Easter Island in 1722 and it's name was given by Captain Admiral Jacob Roggeveen.
The human population growth had a negative effect on the Easter Island.
The ecocide hypothesis is the one explanation to how the human population increased exponentially since its colonization and as such
Human populations did over increased the carrying capacity of the Island to support sustainable crops, and in consequence, the island was severely deforested.
The island's natural cycling of matter and energy also reduced or change and as such the people fought among themselves for scarce resources of the island. They had little food and were starving and they resorted to cannibalism.
The island was also plaque by blackbirding from 1862 to 1863.

matter and energy move through ecosystems between different organisms. how does matter travel through an ecosystem and through earths spheres?
Answer: In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter.

Over 30 children younger than three years of age developed gastroenteritis after visiting a local water park. These cases represented 44% of the park visitors in this age group on the day in question. No older individuals were affected. The causative agent was determined to be a member of the bacterial genus Shigella. The disease resulted from oral transmission to the children. Based only on the information given, can you classify this outbreak as an epidemic? Why or why not? If you were an epidemiologist, how would you go about determining which pools in the water park were contaminated?
Answer:
No this is not an outbreak
Explanation:
No it cannot be classified as outbreak because an outbreak is when the number of affected individuals in an epidemic is much higher as compared to the estimated values. However, an epidemic is the one that affects the people around different countries of the globe.
This can be considered as endemic that is restricted to a certain set of people in a community
I would have studied pattern of movement of affected kids. The common pool to which all these kids visited can be the infectious one. Also one can test the pathogen in infected kinds, and look for similar pathogen in pool water through testing.

Answer:biological parents provide a rearing environment for a child
Explanation:
According to Sandra Scarr's description on the correlation that exist between heredity and the environment, passive genotype-environment correlations occur due to the fact that certain genes evoke environmental support.
It should be noted that passive genotype-environment correlation takes place due to the fact that there's passive inheritance on the genes of the children and the environment which are provided by their parents.An example of such characteristics is when the child is athletically inclined as it's possible for the family to be athletes.In conclusion, the correct option is D.

Answer:

Explanation:
The sequence of events best describes the current theory of the origin of life on Earth development of simple bacteria --> RNA formation --> DNA formation.
What is RNA?According to the hypothesis and researchers, it seems to confirm that RNA was the first genetic or hereditary material that was present in the simple form of bacteria developed first.
RNA is the molecule responsible for the origin of life on the earth and evolved all the required processes and methods for carrying and expressing the genetic information of an organism before DNA. DNA is evolved from RNA molecules of simple bacteria.
Nucleic acid is one of the biological molecules in living organisms. The two types of nucleic acids are DNA and RNA. DNA (deoxyribonucleic acid) is a double stranded biological molecule that stores genetic information in living cells. They are made up of monomers called nucleotides.
