Andrew did a mutant screen with his favorite bacterium that he used for marine phage hunting. He identified three base-substitution mutations on the bacterial recA gene:
Mutant A: A base substitution occurred, which changed T to C, and consequentially abolished transcription of the recA gene.
Mutant B: A base substitution, which changed codon 2 from ACC to ACT, which did not change encoded amino acid.
Mutant C: A base substitution occurred, which changed codon 3 from TCA to a stop codon TGA.
Based on the above info, which of the mutants would still have functional RecA protein?
a. Mutant B
b. Mutant A
c. Mutant C
Answers
Answer:
a. Mutant B
Explanation:
This question is describing a kind of mutation called SUBSTITUTION MUTATION, in which one or more nucleotide base is replaced by another in a sequence. In this case, the base-substitution mutations occcurs in the bacterial recA gene sequence.
However, base substitutions can be grouped into three based on the different results it yields namely: missense mutation, nonsense mutation, silent mutation.
- In Mutant A: A base substitution occurred, which changed T to C, and consequentially abolished transcription of the recA gene. This is an example of missense mutation because it changes the sequence.
- In Mutant B: A base substitution, which changed codon 2 from ACC to ACT, which did not change encoded amino acid. This is an example of silent mutation because it does not alter the sequence of the gene.
- In Mutant C: A base substitution occurred, which changed codon 3 from TCA to a stop codon TGA. This is an example of nonsense mutation because it leads to a STOP CODON.
According to the question, MUTANT B would still have functional RecA protein because it doesn't change the encoded amino acid sequence, which will still lead to the production of the RecA protein.

List and explain types of tropic response in plants?
Answers
Plants exhibit various types of tropic responses, which are directional growth movements in response to external stimuli. Here are four types of tropic responses commonly observed in plants:
1. Phototropism: Phototropism is the growth response of plants towards or away from a light source. Typically, plant shoots exhibit positive phototropism, meaning they grow towards the light, while roots exhibit negative phototropism, growing away from the light. The hormone auxin plays a crucial role in mediating phototropic responses by redistributing growth hormones unevenly in plant tissues.
2. Geotropism/Gravitropism: Geotropism, also known as gravitropism, is the response of plants to gravity. Plant roots exhibit positive geotropism, growing towards the pull of gravity, while shoots exhibit negative geotropism, growing against the force of gravity. The differential distribution of auxin in response to gravity influences the growth patterns in roots and shoots.
3. Thigmotropism: Thigmotropism is the response of plants to touch or mechanical stimuli. It involves directional growth in response to contact with solid objects. For example, tendrils of climbing plants exhibit thigmotropic responses by coiling around supports for stability and attachment. Thigmotropism is often mediated by changes in the growth hormone auxin.
4. Hydrotropism: Hydrotropism is the growth response of plants towards or away from water. Roots typically exhibit positive hydrotropism, growing towards moisture, which aids in water absorption. This response allows plants to effectively navigate their roots towards water sources and ensure their survival in water-scarce environments.
These tropic responses are critical for plant survival and adaptation to their environment. They enable plants to orient their growth towards essential resources such as light, gravity, mechanical support, and water, maximizing their chances of obtaining necessary nutrients and ensuring optimal growth and development. The mechanisms underlying these tropic responses involve complex interactions between hormones, growth factors, and environmental cues, allowing plants to respond and adapt to their surroundings.

How come a person can only increase his/her oxygen levels in the body by only three to five percent when hyperventilating?
Answers
Answer:
Hyperventilating can only increase a person's oxygen levels in the body by only three to five percent because the body has a natural mechanism to regulate the levels of oxygen and carbon dioxide in the blood. When a person hyperventilates, they exhale more carbon dioxide than they inhale, which leads to a decrease in carbon dioxide in the blood. This decrease in carbon dioxide causes the blood vessels to constrict, which reduces the amount of oxygen that can be delivered to the body's tissues. This is why hyperventilating can only increase a person's oxygen levels in the body by a small amount.

DNA analysis indicates that the genes for antibiotic resistance are not normally present in bacterial chromosomal DNA. Which of the following statements best explains how the genes for antibiotic resistance can be transmitted between bacteria without the exchange of bacterial chromosomal DNA?
a. The antibiotic-resistant bacteria release a hormone that signals neighboring bacteria to become resistant.
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
c. The antibiotic-resistant bacteria are the result of bacteria that specifically modify their own chromosomal DNA to neutralize the antibiotics

b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
Explanation:
Transformation is a genetic process by which bacteria take up foreign genetic material from the surrounding environment. In consequence, this process does not involve direct cell-to-cell interaction. Transformation allows the occurrence of horizontal gene transfer (HGT) events among different bacteria capable of exchanging extrachromosomal DNA plasmids, thus increasing genetic diversity in bacteria.

What is the main strategy birds use to maintain their body temperature?
A-using energy from food to keep their bodies warm
B- nesting in warm, sunny location
C- eating warm food on cold days
D- spending the day in the shade of trees
Answers
Birds are endothermic, which means they generate their own body heat. They have a high metabolic rate and generate heat by breaking down food. This heat is then used to maintain their body temperature. To conserve this heat, birds have adaptations such as feathers, which provide insulation, and a high surface-to-volume ratio, which reduces heat loss. Birds can also fluff up their feathers to create air pockets that trap heat close to their bodies.

In Activity 2, which of the respirometers serves as a control? Explain your answer! Why was it the control? You should write at least 3 sentences to explain this. Respirometer A contains germinated beans. respirometer B contains dormant beans and plastic beads respirometer C contains plastic beads.
Answers
In Activity 2, the respirometer C serves as the control. A control is an essential part of any scientific experiment as it provides a baseline against which the experimental results can be compared.
Respirometer C containing only plastic beads does not contain any living organisms and therefore does not undergo cellular respiration. By comparing the results of respirometers A and B with the control (respirometer C), any changes in oxygen consumption and carbon dioxide production can be attributed to the metabolic activity of the germinated beans in respirometer A and the dormant beans in respirometer B.
This allows researchers to determine the specific effects of germination on cellular respiration by isolating the variables and eliminating any external factors that could influence the results.

The two geological processes involved in changing an igneous rock to a sedimentary rock are weathering and erosion. Weathering is the breakdown of rocks due to physical or biological processes, while erosion is the transport of weathered rock materials.
Thus, the two geological processes involved in changing a sedimentary rock to a metamorphic rock are heat and pressure which changes the minerals and textures of the sedimentary rock and a metamorphic rock is formed.
The two geological processes involved in changing a metamorphic rock that has been developed from sedimentary rock to an igneous rock are melting and solidification. James Hutton developed a model that explains the rock cycle which explains that the geological processes of Earth operate continuously and uniformly over long periods.
