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:

The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

I'd love to hear you explain this to a Muslim or Islam. Why pick on Christians and not Hindus or Buddhists? You are saying they are wrong by claiming evolution is real. Also, maybe give some evidence next time you blindly state information.

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.

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.

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.

more exposure to sunlight and therefore increase photosynthetic production

Explanation:

Answer:

c. Frame shift mutation.

Explanation:

Frame shift mutation is a type of mutation which causes more damage to the DNA of the cell. It causes changes in the amino acid sequences in a polypeptide chain. Point mutation is a type of mutation in which only one amino acid changed, while on the other hand, frameshift mutation changes the whole sequence of amino acids so we can say that frame shift mutation is more damaging to the DNA molecule.

Development of simple bacteria --> RNA formation --> DNA formation

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.

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.

Therefore, The sequence of events best describes the current theory of the origin of life on Earth development of simple bacteria --> RNA formation --> DNA formation.

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.

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.

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.

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.
