Answer:

Viruses like Influenza reproduce via the lysogenic cycle.

Explanation:

Viruses are pathogenic, disease-causing microorganisms. They reproduce and spread in a variety of ways, and their life cycle or lytic cycle influences the symptoms of their specific infections.

Influenza viruses, in particular, exploit receptors on the cell surface for entry into the cell. They reproduce by using the host cell's replication mechanism in the nucleus. They and use the host's cellular machinery in order to replicate.

This cycle usually lasts for 2-7 days, after which the virions bus from the host cell, incorporating parts of their lipid bilayers. The viral particles spread via infective particles or droplets from the lung tissue of their host.

What are the biological structures
vesna_86 [32]

Answer:Biological structures are able to adapt their growth to external mechanical stimuli and impacts. For example, when plants are under external loads, such as wind force and self-weight, the overloaded zones are reinforced by local growth acceleration and the unloaded zones stop growing or even shrink. Such phenomena are recorded in the annual rings of trees. Through his observation of the stems of spruce, K. Metzger, a German forester and author, realized that the final goal of the adaptive growth exhibited by biological structures over time is to achieve uniform stress distribution within them. He published his discovery in 1893.12 A team of scientists at Karlsruhe Research Centre adopted Metzger's observations and developed them to one single design rule: the axiom of uniform stress. The methods derived from this rule are simple and brutally successful like nature itself. An excellent account of the uniform-stress axiom and the optimization methods derived from it is given by Claus Mattheck in his book ‘Design in Nature’.13 The present study utilizes one of these methods, stress-induced material transformation (SMT), to optimize the cavity shape of dental restorations.

Describe what molecular biologists mean by an rna world
Karo-lina-s [1.5K]
<span>The RNA world is the hypothesized format of chemical life that existed prior to our current DNA and RNA world. In the RNA world, RNA molecules formed in the primordial soup and began to evolve by self-replication and mutation. This led to increased complexity, natural selection of "better" RNA and diversification of RNA based life.</span>

On the graph below, what would explain why the rabbit population levels drastically increased instead of decreasing drastically?
Ilia_Sergeevich [38]

Based on factors affecting population, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

<h3>What is population increase?</h3>

Population increase refers to the increase in the number if species of an organism found in a given habitat over time.

Increase in population can be brought about by factors such as;

  • abundance of food
  • high fertility rate
  • favorable environmental conditions
  • lack of predators

Therefore, the rapid increase in the rabbit population could be dues to high fertility rate, abundance of food and lack of predators.

Which two features indicate that a cell is a plant cell and not an animal cell? A. cell membrane, flagella B. lysosome, vacuole
Triss [41]
c. cell wall, vacuole

Among the choices above, the two features that indicate that a cell is a plant cell is the cell wall and vacuole. The cell wall can only be found in plant cells. It is the rigid cell that surrounds the cell membrane. The vacuole of a plant cell and animal cell are way too different. The vacuole of an animal cell is usually more than one and small, even smaller that that of the plant cell. On the other hand, the vacuole of the plant cell is only one in fact a large one that takes up almost 90 percent of the volume of the cell
