The correct sequence for the general adaptation syndrome is:_________
a) Exhaustion phase, alarm phase and resistance phase
b) Alarm phase, resistance phase and exhaustion phase
c) Resistance phase, exhaustion phase and alarm phase
d) Alarm phase, exhaustion phase and resistance phase
Answers
Answer:
The correct sequence for the general adaptation syndrome is: b) Alarm phase, resistance phase and exhaustion phase
Explanation:
The general adaptation syndrome describes what happens to our body when it is under stress.
The first phase is the Alarm phase. In this stage, the body activates the fight or flight response, causing an increase in adrenaline and cortisol, blood pressure, respiratory frequency, amongst other things that prepare us to react in a situation that we perceive as dangerous.
The second phase is the resistance one. During this phase, the body undergoes a different process that adapts it to manage the stress, with an elevated amount of cortisol and blood pressure.
The third phase is the exhaustion phase. If the stress levels continue to be high, the body passes to this stage. The body is exhausted and cannot keep dealing with stress, which causes mental and physical problems such as anxiety, depression, fatigue, stress-related illnesses, among other symptoms.
A plasmid that encodes resistance to ampicillin and tetracycline is digested with the restriction enzyme PstI, which cuts the plasmid at a single site in the ampicillin-resistance gene. The DNA is then annealed with a PstI digest of human DNA, ligated, and used to transform E. coli cells. (a) What antibiotic would you put in an agar plate to ensure that the cells of a bacterial colony contain the plasmid
Answers
Answer:
tetracycline
Explanation:
When the DNA insert is ligated in Pstl site, the ampicillin gene is disrupted while tetracycline gene is still intact.
- If the bacterial colony is growth in a medium with only ampicillin, only the cells that contains the plasmid with the insert will grow.
- If the bacterial colony is growth in a medium with only tetracycline, the cells which have incorporated the plasmid will survive. We cannot distinguish between cells with plasmid + insert and plasmid alone.
- If the bacterial colony is growth in a plate with ampicillin + tetracyclin, only the cells with the plasmid without the insert will grow.
Therefore, to ensure that the cells of a bacterial colony contains the plasmid, they have to be seeded in a plate with tetracycline.

Agrobacterium, a tumor-producing bacterium that infects plants, has been of recent interest because of its possible use as a vector for genetically engineering plants.
A. True
B. False
Answers
Answer:
A. True
Explanation:
A tumor producing bacteria named Agrobacterium tumefaciens is very much in use in the field of biotechnology recently. The bacteria consists of a tumor producing gene that is incorporated in the plasmid called as 'Ti plasmid' or the tumor causing plasmid. The gene of the interest is incorporated in the plasmid and the plants is infected by it. In this way the plant receives the gene interest.
This agrobacterium can be used as a vector in the genetically engineered plants.
Hence the answer is true.

Explanation:
Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.
Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.

The tropical regions are warmer than the polar regions due to the angle of the Sun's rays. As a result, there is generally higher pressure at the poles and lower pressure at the equator, so which way does the wind blow on Earth's surface.... Answers --> A. The wind blows cold air toward the equator from the poles.... B. The wind blows warm air from the poles to the equator..... C. The wind blows cold air from the equator to the poles...... D. The wind blows warm air from the equator to the poles
Answers
Answer is Letter B
The wind blows warm air from the poles towards the equator on the surface of the Earth. So, the correct option is B.
What is Wind?Wind is defined as the natural movement of air or other gases relative to a planet's surface which occurs on a variety of scales, from thunderstorms lasting tens of minutes, to land masses lasting a few hours. The wind blows warm air from the poles towards the equator on the surface of the Earth.
Global winds result from differences in the absorption of solar energy between climate zones on Earth, to local breezes that results from the warming of land surfaces. Gentle or moderate wind is known as the breeze while strong and gusty wind is known as the storm, when accompanied by thunder and lightning and small gusts of wind moving at high speed are known as gusts.
So, the correct option is B.

Answer:
Yes, this lab will address the lesson question.
The procedure shows two different food situations—three foods and two foods.
However, the initial populations of birds are the same.
Therefore, in the end, you can compare generation three for each food situation and measure the effect of the food change.

Which of the following factors most likely triggers arousal from hibernation?
A) the sun rising in the morning B)snow falling onto the ground
C) the environmental temperature dropping below 0 °C
D) a significant decrease in the animal's respiration rate
Answers
Answer:
A) the sun rising in the morning
Explanation:
In biology, hibernation refers to a physiological state where a plant or animal is metabolically inactive in the winter period (characterized by extreme cold). As far as the animal or plant is concerned, the cold weather during winter is an adverse condition, hence, they undergo hibernation in order to conserve their energy.
According to this question, arousal or wakening from hibernation would be triggered in the presence of heat source, which in this case is the SUN RISING IN THE MORNING.

Answers
Answer:
Viruses replicate only inside host cells.
Explanation:
Viruses are not used as evidence to support the cell theory because they are not considered a cell and cannot carry out vital life processes without getting into host cells.
According to the cell theory, the cell is the basic unit of life, all living organisms are made up of cells and cells arose from preexisting cells. A virus that is not in a host cell is just a piece of DNA/RNA surrounded by a protein coat and is not capable of carrying out any life process for it to be considered living.
Viruses are only able to reproduce and multiply when they get access to a living host. They use the genetic mechanisms of the host to replicate their DNA/RNA using the lytic or lysogenic cycle. Hence, they are not used to support the cell theory.

Explanation:
In Leonardo da Vinci’s time, nobody knew that the arteries were joined to the veins by tiny, invisible capillaries. This means that even though he studied the heart in detail, he thought that the arteries and veins were dead ends. Why did this make it difficult for him to understand how the heart worked?
Answers
Answer:
It was difficult for him to understand how the heart worked because he wasn't fully aware of the pumping mechanism of the heart and how the circulation of blood goes inside the body. Not seeing the capillaries meant that the heart pumped blood towards the vessels and into a dead end. He couldn't understand where the blood that was being pumped goes to.
Explanation:
Leonardo da Vinci is considered one of the earliest persons to study the heart. Although he made an exceptional observation of the different parts of the heart, he couldn't track the capillaries. He didn't know that these tiny structures connected the arteries and the veins. He believed that the heart was meant to transfer heat from the liver going to the muscles. He also believed that the lungs helped cool the blood.

Genetic variation
Explanation:
Genetic variability (diversity) stems from two basic processes: mutation and recombination.
If there were no mutations, all genes would exist in only one form, they would not have alternative forms.
Since phenotypic variability also depends on genetic variability, it is clear that the processes of mutation and recombination contribute to the creation of a large number of different phenotypes.
