Answer:
Bacteriophages have a lytic or lysogenic cycle.
Explanation:
The lytic cycle leads to the death of the host, whereas the lysogenic cycle leads to integration of phage into the host genome. Bacteriophages inject DNA into the host cell, whereas animal viruses enter by endocytosis or membrane fusion.
Together organ systems make us healthy and living.
Answer:
The question is incomplete as there are no options, the options are:
What would be the next step in this experiment?
A. construct a hypothesis and record data
B. make observations and draw a conclusion
C. ask questions and construct a hypothesis
D. analyze the results and make a conclusion
The answer is D
Explanation:
According to this question, a student performs an experiment where she places apple fruit on one location and places apple and banana together in another location. She follows the steps of the scientific method in performing this experiment.
The steps involved in the scientific method include:
- Making an observation
- Constructing an hypothesis
- Testing the hypothesis (experimentation)
- Analyse the result
- Draw a conclusion
The student in this question has already made the observation that when bananas are kept near other fruits, the other fruits ripen faster. She has hypothesized that bananas must have an influence on the ripening process. She tests the hypothesis via an experiment described above. Hence, the next step is to ANALYZE THE RESULTS she will get after 5 days and DRAW A CONCLUSION based on that.
What animals did the grant study in galapagos island?
Galapagos finches did the grant study in Galapagos island.
Galapagos finches is a piece of evidence supporting the theory of evolution.
Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.
What did he observe?
During the survey voyage of HMS Beagle, Darwin was unaware of the significance of the birds of the Galapagos. He had learned how to preserve bird specimen while at the University of Edinbugh and and had been keen on shooting, but he had no expert in ornithology and by this stage of the voyage concentrated mainly on geology. Nonetheless, these birds were to play an important part in the inception of Darwin’s theory of evolution by natural selection.
What was the brief goal of their studies?
All of Darwin's observations and insights, plus reading of increasing population growth and demand for limited resources, brought him to his theory of natural selection. Briefly, this means that individuals better adapted to their environment survive and increase in number through reproduction.
What did they conclude?
Conclusion:
Charles Darwin deserves primary credit for the theory of evolution. He developed existing ideas about descent with modification while providing a large body of evidence in support of them, and he was the first person to perceive thatnatural selection is the primary force behind evolution.
<h2>Co-evolution </h2>
Explanation:
A series of reciprocal adaptations in predator and prey populations describes co-dependence or co-evolution
- In co-evolution, two species which are in association evolve together due to their relationship
- Both the species have different ancestry
- Interactions exhibited by co-evolution are: host parasite interaction, prey predator association, evolution of long proboscis in insects for taking nectar from flowers
- Predation is a very short term behavior in which two different species interact with each other for the demand of energy, one is prey and the other is predator
- For successful predation, predator wants minimum energy investment and maximum energy
- Increase in prey population in any given area attracts predator population, hence population of predator also increases in that area
- Increase in predator population results in decrease in prey population after some time decrease in prey population leads to decrease in predator population also
