Tommy is investigating a strain of bacteria. He observes that the bacteria is only found in environments with a pH range from 6 to 8. His lab partner prepares a growth medium for this bacteria with a pH of 5. Which explanation best predicts what will happen to the bacteria grown in this growth medium?
A
The bacteria will quickly die because the growth medium is too acidic for survival.
B
The bacteria will grow quickly and then begin to die because they will run out of food.
C
The bacteria will grow slowly because the growth medium will provide fewer resources.
D
The bacteria will grow quickly because they can change the pH level of the growth medium.
Answer: A
The bacteria will quickly die because the growth medium is too acidic for survival.
Explanation: it was only found in 6 to 8 pH range so it will not survive in pH of 5

Answer:
A. cycled by carbon-fixing bacteria
Explanation:
This process is also called "Biological carbon fixation."
Here is a more in-depth answer:
Biological carbon fixation or сarbon assimilation is the process by which inorganic carbon (particularly in the form of carbon dioxide) is converted to organic compounds by living organisms. The compounds are then used to store energy and as structure for other biomolecules.

The french taxonomist who, in 1809, was the first scientist to suggest that organisms that use one part of their body repeatedly would increase their ability was Jean Lamarck
Organisms will not pass acquired physical traits to the next generation.
In his theory, Lamarck proposed how species adapted to the changed environment by passing down acquired physical traits to the next generation. But, after Charles Darwin published his theory of evolution, Lamarck's theory was rejected. Now, it is known that acquired physical traits could not be inherited and epigenetics is a good proof for that.

Suggest 2 types of learned behaviors and two innate behaviors that you have observed in animals (cats, dogs, whales, humans)
A persistent change in behavior that develops through experience is called Learned behavior. They can be developed by trial and error methods.
What do you mean by Behaviors?Behaviors may be defined as the observable response of organisms to external or internal stimuli.
The two examples of learned behaviors include operant learning (rat pressing lever experiment) and classical conditioning (Food and bell experiment).
The two examples of innate behaviors include feeding their young ones by humans, and fighting against male stickleback fish.
Therefore, it is well described above.

Does biomass contribute to global climate change?
Biomass may contribute to global climate change because certain trophic levels produce greenhouse gases.
What are greenhouse gases?Greenhouse gases are specific types of gases that can maintain heat (solar radiation) on Earth's surface and thus increase Earth's temperature.
The ruminant animals produce methane, which is an important greenhouse gas associated with the global climate.
In consequence, the sudden increase in animal husbandry due to human activities may also increase the effects of climate change.

Create two Punnett squares for a fictional trait, “Star-bellied.” “S” represents a dominant star-bellied gene, and “s” represents the recessive trait. For the first Punnett square, the mother and father both have star bellies and the recessive gene; what is the chance their child will have a star-belly? For the second square, the mother has a star-belly and the recessive gene, and the father does not have a star-belly; what is the chance their child will have a star-belly?

In humans, free earlobes (F) is a dominant trait to attached earlobes (f) . If parents with the genotypes FF have a child, what is the probability that the child will have earlobes different from its parents?
Answer:
0%
Explanation:
Mother: FF
Father: FF
From the Punnet Square, we can conclude that the only possible genotype from these parents is FF --> free earlobes.
This means that there is a 0% chance of having a child with attached earlobes.
