Researchers think the cheetah population in Africa experienced extremely low numbers around 10,000 years ago, and then also again around 100 years ago. During both times, the low numbers rebounded back. Predict the consequence of this on the cheetahs of today.
a. Cheetahs are a very resilient population and unlikely to become extinct.
b. Cheetahs today are the strongest and fastest cheetahs ever.
c. Cheetahs today have very little genetic variation.
d. Cheetahs today are slower than those before the population fell.
Answers
Answer:
Cheetahs are a very resilient population and unlikely to become extinct.
Explanation:
LH Gunderson (2000) Defined ecological resilience as "the amount of disturbance that an ecosystem could withstand without changing self-organized processes and structures."
When a population is resilient, it tends to bounce back after major perturbations.
For instance, the Cheetah population was at the brink of extinction around 10,000 years ago, and then also again around 100 years ago yet the population was able to recover at both periods and never went extinct.
This implies that Cheetahs are a very resilient population and unlikely to become extinct.
Answer:
c. Cheetahs today have very little genetic variation
Explanation:
Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.
Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.
Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.
In the exposed example, the low numbers of cheetah around 10,000 years ago, and then also again around 100 years ago, might have been due to some natural disaster or extensive hunting that acted as a pressure that significantly reduced the number of animals. Probably, the population experienced one or many small-sized generations. Even though the low numbers rebounded back, the survivors did not have the whole genetic pool of the original population, meaning the genetic diversity might not have recovered. When the small groups increased in size, they had a genetically different composition from the original one. There is a reduced genetic variability, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation. It might involve even more individuals each time and increase the probability of developing a genetic disease.

When it was time to go outdoors, 3-year-old Casandra said she didn’t want to play and headed for her locker. At the teacher’s gentle insistence, Casandra reluctantly joined the other children on the playground. Tears rolled down her cheeks when the teacher boosted Casandra onto a swing seat and began to push her. The teacher stopped the swing and helped Casandra off. She held her closely for a few minutes and then asked why she was crying. Casandra initially denied that anything was wrong. However, when the teacher persisted, said she "had fallen the night before and hurt her bottom."
The teacher took Casandra inside and asked to see where she had been hurt. When Casandra pulled down her shorts, the teacher noted what appeared to be a large burn with blisters approximately 2 inches in length by 1 inch in width on her left buttock. Several small bruises were also evident along one side of the burn. Again, the teacher quietly asked Casandra how she had been hurt, and once again she replied that she "had fallen."
What actions should Casandra’s teacher take?
Answers
Answer:
casandra was scared around others
Explanation:
in the passage i notesed that she went to her locker and started crying
Answer: 1. Casandra's teacher should take her to the nurse and just tell the nurse that she got hurt in the playground 2. The teacher should gather more evidence until she knows that something is going on because she can't prove that something is really happening 3. She shouldn't tell the parent yet because they would probably accuse the teacher of doing it 4. If it was the first time , I would feel bad for the girl and just tell her to be careful but if it kept happening, I would tell the principal and her parents and I would feel angry

Which of the following situations would be most likely to engage the anterior cingulate cortex?
A waiter walks over to your table at a restaurant and holds an open menu in front of you.
You walk into the elevator of your apartment building and press the button for your floor.
You enter your classroom and find someone sitting in your usual seat.
A good friend asks you to remind him of your telephone number.
Explanation:
In order to meet the demand of the surrounding environment by adjusting the motor outputs from the brain to the environments ,a part of the emotion control part of the brain( limbic system) called the anterior cingulate cortex is responsible for this.
Anatomically, the limbic system is made up of the primarily the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia and cingulate gyrus.
Based on the this its(anterior cingulate cortex) functions are formation of emotion in the limbic system, and possessing of memory and learning.
it is also a major parts of of pain networks for pain modulation and perception.
Therefore whenever there is change in the environment from the prestored condition in the brain,(e.g the usual seat in the class room occupied above) the anterior cingulate cortex adjust the motor input from the brain to adapt to the new environment to take an action,whih in this case leads to the reclaiming of the seat or any other necessary proactive action.

When observing an ECG, you will see many different deflections from baseline known as waves. These deflections represent various electrical events taking place in the heart that give rise to the mechanical events that help move blood. In addition to the waves that can be observed, there are flat lines between waves and successive cardiac cycles called segments that also represent particular electrical events that take place in the heart. Finally, certain combinations of waves and segments, known as intervals, also identify important events recorded by the ECG. Match each of the following events with the correct phase of an ECG. Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
A. P wave
B. ST segment
C. QRS complex
D. PR segment
E. T wave

Answer:
1. Ventricular depolarization −−QRS complex
2. Total time it takes for the ventricular muscle to depolarize and repolarize −−QT interval
3. Atrial depolarization −−P wave
4. Conduction through the atrioventricular (AV) node −−PR segment
5. Ventricular repolarization −−T wave
6. The ventricles are in their depolarized state −−ST segment
7. Conduction through the atrioventricular (AV) bundle −−Q wave
Explanation:
ECG or electrocardiogram is the graphical representation of the heart's rhythm and electrical activity measured by electrical signals. The contraction of the heart shows electrical activity.
There are various deflections shows from baseline and known as specific waves and there are also some flat lines between waves called intervals. This atrial depolarization is called P wave and ventricular repolarization called T wave and the time between ventricular muscles depolarization ( QRS complex) and repolarization is QT interval. Conduction through the atrioventricular (AV) bundle is known as Q wave.

A. Methane gas
B. Vehicle exhaust
C. Building materials
D. Industrial emissions
Answers
Indoor air pollutants can be dangerous because the air pollutants stay in small space rather than circulating throughout the atmosphere. Option C is the correct answer.
What is the methane gas ?It is the gas that is produced by the cow dung and the gas is produced by the various chemical reactions in it.
Building materials pollution can be reduced out by many ways. Here are a few examples:
Low-VOC Paints: Volatile Organic Compounds (VOCs) are chemicals found in many paints, which can emit harmful fumes into the air for years after the paint has dried. Low-VOC paints contain fewer or no harmful chemicals, reducing indoor air pollution and improving air quality.
Air-Purifying Plants: Certain indoor plants, such as peace lilies, spider plants, and Boston ferns, can help remove harmful pollutants from the air. These plants absorb pollutants such as formaldehyde, benzene, and xylene, improving indoor air quality.
Green Roofs: Green roofs are roofs covered in vegetation that can help absorb pollutants from the air, reducing air pollution in urban areas. Green roofs also provide insulation, reducing energy costs, and can help mitigate the urban heat island effect.
Therefore ways like these should be adopted.

According to the base-pairing rules for DNA, which of the following statements is
not true?
A always pairs with T.
C always pairs with G.
Talways pairs with G.
Answers
Answer:
T always pairs with G
Explanation:
According to the complementary base pairing rule as postulated by Chargaff, an Adenine base (A) will always hydrogen pair with a Thymine base while Cytosine base (C) will always hydrogen pair with Guanine base (G) in a DNA molecule.
That is; A - T and G - C
Hence, based on the question, the pairing of Guanine and Thymine is incorrect.
