Which of the following responses correctly lists the order of events in a generalized viral replicative cycle?
A) the virus enters the cell, enzymes transcribe the viral genome into mRNA, host enzymes replicate the viral genome
B) enzymes transcribe the viral genome into mRNA, the virus enters the cell, host enzymes replicate the viral genome
C) host enzymes replicate the viral genome, enzymes transcribe the viral genome into mRNA, the virus enters the cell
D) the virus enters the cell, host enzymes replicate the viral genome, enzymes transcribe the viral genome into mRNA
The correct order of events that happens during the generalized viral replicative cycle is the virus enters the cell, enzymes transcribe the viral genome into mRNA, host enzymes replicate the viral genome. Thus, the correct option is A.
What is generalized viral replicative cycle?Viruses does not have the machinery to replicate themselves hence, they require host for replication and division. There are two processes which are used by the viruses to replicate inside the host cell: the lytic cycle and lysogenic cycle. Some viruses can reproduce using the both methods, while others can only use the lytic cycle to reproduce. In the lytic cycle, virus attaches to the host cell and injects its DNA into the host DNA.
The virus replicative cycle could be divided into six steps which include: first, the attachment of virus into the cell, the virus penetrates host cell, uncoating, followed by the transcription of the mRNA of the viral genome i.e., gene expression and then host enzymes replicate the viral genome, assemble, and release the content.
Therefore, the correct option is A.

In this illustration, the small blue spheres represent water molecules. Sections A and B are divided by a membrane, with section A containing fewer water molecules than section B. In which direction will water molecules move across the membrane? Sections A and B are divided by a membrane, with section A containing fewer water molecules than section B Question 9 options: Water will move from A to B There will be no net movement of water. Water will move from B to A.
Through an osmotic process, water can freely go from a more diluted solution to a less diluted one. It follows its concentration gradient and does not need energy. Option 3 (or C) Water will move from B to A.
What is osmosis?
Osmosis is a simple passive transport process through which water molecules move from one side to the other of the membrane.
Water follows its concentration gradient, so it does not need energy to be transported. Water moves from the most diluted side to the more concentrated one.
When dilutions have different concentrations, there is a difference in the number of water molecules moving from one side to the other.
Solutions reach a dinamic equilibrium when concentrations at each side of the membrane are the same.
In the exposed example, sections A and B are separated by a semi-permeable membrane, and A contains fewer water molecules than B.
Water will move from A to B ⇒ NOThere will be no net movement of water ⇒ NOWater will move from B to A ⇒ YES
Water moves from B to A because in section B there is a greater concentration of water than in A. So water follows its concentration gradient and moves forward to A.
Option 3 is correct.

The answer of the query is the 3 laws of inheritance proposed through Mendel encompass: regulation of Dominance, regulation of Segregation, law of independent collection.
Whilst an organism makes gametes, every gamete gets simply one gene reproduction, which is chosen randomly. that is referred to as the regulation of segregation. A Punnett rectangular can be used to predict genotypes and phenotypes of offspring from genetic crosses.
Mendel's law of unbiased assortment states that the alleles of extraordinary genes get taken care of into gametes independently of each other. In different words, the allele a gamete gets for one gene does not have an effect on the allele obtained for every other gene.

why it is advantageous for population to occupy different habitats
According to the research, the correct answer is that it helps to acquire divergent and adaptive evolutionary changes. It is advantageous for population to occupy different habitats since they live in different ecological environments which allows them to have divergent evolutionary changes and better adaptation.
What is a population?It is the set of organisms that is formed by a group of specimens of the same certain species that share a habitat.
In this sense, when these organisms of the same species occupy different habitats, it allows the development of new types of species that can survive with environmental variations and adapt to environmental conditions in a different way than the rest, generating divergent evolution.
Therefore, we can conclude that according to the research, a population is a set of individuals of the same species that when occupying different habitats adapt to a process of divergent evolution.

After the oil spill, marine microbes consumed the oil under the surface but also removed ________ from the water, killing both plants and animals and creating dead zones.
Microbes consume the oil under the surface but also remove oxygen.
How microbes clean oil spill?Bacteria can break down oil into carbon dioxide and water. However, no single organism can degrade all the components of crude oil and refined fuels that enter the environment. The tens of thousands of different compounds that make up petroleum can only be biodegraded by groups of microorganisms acting in concert.
Pseudomonas putida, also known as oil eater, is a Gram-negative, rod-shaped saprophytic bacterium patented by Ananda Mohan Chakravarti for the bacterium's ability to biodegrade oil.

This information, along with the discovery that rocks along the mid-Atlantic ridge were younger, was evidence for which of the following activities?
nswer
A
Seismic activity
B
Seafloor spreading
C
Gravitational pull
D
Volcanic activity
This information, along with the discovery that rocks along the mid-Atlantic ridge were younger, was evidence for Seafloor spreading.
What is seafloor spreading?
Seafloor spreading is the hypothesis that the ocean's crust develops along the mid-ocean ridge system's undersea mountain zones and spreads out laterally away from them. The theory of plate tectonics, which revolutionised geologic thought throughout the final quarter of the 20th century, was developed in large part as a result of this concept.
When the seafloor spreads, tectonic plates, which are huge portions of the Earth's lithosphere, split apart from one another. Seafloor spreading and other tectonic activity processes are caused by mantle convection. Mantle convection is the term for the mantle's slow, turbulent circulation.
Hence the correct option is B; seafloor spreading.
