In general, when recombination experiments are conducted with bacteria, participating bacteria are mixed in complete medium, then transferred to a minimal growth medium. Why isn't the protocol reversed: minimal medium first, complete medium second?
We can confirm that if we used a minimal medium first and attempted to transfer from that to a complete medium second, certain types of bacteria would not be able to survive the first medium.
What bacteria would be affected?This has to do with many kinds of bacteria, but particularly auxotrophs. These are bacteria who have trouble producing the substances they need to survive, so in an incomplete medium, these bacteria would not have a high chance to survive until moved to the complete medium.
Therefore, we can confirm that if we used a minimal medium first and attempted to transfer from that to a complete medium second, certain types of bacteria would not be able to survive the first medium.

Plants have openings on their leaves called stomata, through which gases, including water vapor, can pass in and out of the plant. Plants open and close stomata in order to regulate the exchange of gases with the atmosphere. Why might it benefit plants to keep their stomata closed under certain conditions?
Plants open and close stomata in order to regulate the exchange of gases with the atmosphere. It benefits plants to keep their stomata closed under certain conditions is to conserve water and to prevent damage from excess light and high temperatures.
What is stomata?
Stomata are tiny pores on the surface of the leaves that allow plants to exchange gases such as carbon dioxide and oxygen.
When stomata are open, water vapor can escape from the plant, leading to transpiration. In a condition of drought and high temperatures, closing stomata can help the plant conserve water.
When light intensity is too high, closing stomata can help the plant protect the plant from stress.
Therefore, closing the stomata can help the plant conserve water and prevent damage from excess light and high temperature.

According to the gate control theory, what is one reason we are able to block the perception of pain?
Answer:
Gate theory claims that pain sensations must pass through a space, or gate, in the spinal cord, which can be closed to block pain signals sent from the brain or peripheral receptors.
Explanation:
According to the gate control theory, the activities of large fibres cause the excitation of inhibitory neurons. This reduces the transmission of pain signals.
What is gate control theory?
This is a type of defence mechanism by our nervous system. In this mechanism, the signals that are sent to the brain, by the spinal cord for the perception of pain, are managed by the spinal cord itself.
This may include the mechanism of reducing or increasing the pain. Therefore, the gate theory can heighten or decrease the perception of pain meaning the gate can either be closed or it can be open. The pain signals will pass to the brain if the gate is open and they will be restricted to the spinal cord if the gate is closed.
A painful or noxious stimulus of pain can be restricted or managed by a non-noxious stimulus. Like a backache can be managed by a gentle back massage.
Therefore, a gate control mechanism helps in blocking the perception of pain in the spinal cord.

Write a “lifeline” of a robin over the first year of its life. Include important events.
Explanation:
Robins are born in the spring or summer and are mature birds and ready to breed in the following spring or summer. They do not mate for life. Pairs usually remain together during an entire breeding season, which can involve two or three nestings. However, in spring, sometimes a male and female who mated the previous year will both return to the same territory and end up together for another year. This happens most frequently when they were successful raising babies the previous year. Robins lay one egg per day, for a total of 5–6 eggs in a clutch. The eggs hatch about 12 - 14 days after the last egg was laid. Baby robins jump from their nest when they are about 13 days old, but the range is 9 - 16 days. After leaving the nest (fledging), it takes another 10-15 days for babies to become strong fliers and independent birds. The parents continue to feed their young during this period.
Most robins die their first year. But the lifespan goes up dramatically for the ones that survive this critical time, because they've learned so many important life skills. Of those that survive their first year, most wild robins live to be about 5 or 6. As of February, 2001, the longest-living banded wild robin ever recorded had survived 13 years and 11 months, according to the Bird Banding Laboratory at the Patuxent Wildlife Research Center. In captivity, robins have survived longer than 17 years.
Answer:
In the spring, robins travel north and mate. Much chirping and singing go on among the robins before they mate. The eggs are fertilized inside the female's body. Newborn robins are nearly helpless. Their eyes are closed. They cannot feed themselves, so their parents get insects and bring them to the young. When another animal or bird gets near the nest, the parents protect the young robins. After the little robins grow enough to survive on their own, they are pushed from the nest by the parents.

Which of the following best explains how higher concentrations of nitrogen and phosphorus contribute to eutrophication?
Answer:
See the answer below
Explanation:
It seems that you forgot to include the options for the question.
Nevertheless, one of the best explanations for how higher concentrations of nitrogen and phosphorus contribute to eutrophication is the fact that after light, both nutrients represent the most important limiting factor for algal growth. The overabundance of these two nutrients leads to the stimulation of the growth of various algal species present in the ecosystem, eventually causing what is referred to as algal bloom.
Apart from constituting a nuisance to waterways, the bloom of algae causes a host of problems to the environment which include the blockage of sunlight from getting to water bodies, the release of toxins into water by algal species, hypoxia of water bodies, and eventual death of aquatic species.

In 1915, the scientist Thomas Hunt Morgan discovered that certain genes on chromosomes are associated with specific traits in fruit flies. However, the mechanism through which this process occurs was not detailed until 1966. That is when Marshall Nirenberg and several other scientists demonstrated that specific sequences of nucleotides in DNA correspond to specific proteins. After gene sequencing was introduced in 1977, scientists were able to use Nirenberg's discoveries to predict an organism's proteins from its DNA sequences.
How does the information above illustrate the nature of science?
A.
It shows that scientific progress is made primarily through observational rather than experimental evidence.
B.
It shows that earlier scientific ideas are typically incorrect since genes code for proteins and not traits.
C.
It shows that scientific ideas are durable but are developed as new data are collected.
D.
It shows that scientists like Nirenberg did not rely on ideas of others in making major discoveries.
