How does an individual with a competitive advantage lead to the evolution of an entire species?(1 point)
A) Some individuals are better at competing for resources, and that allows them to survive droughts or other major ecological events, leading to the extinction of certain species and the survival of others.
B) Traits that are advantageous help certain individuals reproduce at higher rates, so those traits are more common within the population.
C) Those who have traits that help them survive are able to reproduce, and their offspring have those traits, leading to a change in the species over time.
D) Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland.
Answer: the answer i belive it is; is D
An individual with a competitive advantage lead to the evolution of an entire species because : ( D ) Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland.
Evolution of speciesThe evolution of species is the change in the characteristics of species overtime and this is made possible through natural selection. Individuals with competitive advantage survives better than individual without competitive advantage therefore they lead to the evolution of species through natural selection by expanding their range.
Hence we can conclude that Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland.

Describe briefly the quark model of hadrons, including the properties of quarks.
Answer:
Experiments in which electrons are scattered from nucleons have revealed that neutrons and protons are not fundamental particles but are composed of yet smaller particles, quarks. There are three quarks: up, down and strange and each has a corresponding antiquark of opposite charge.
Explanation:
Suppose you travel to a tropical place like the Bahamas and watch the coastal poikilotherms, such as fish, crabs, and starfish, swim and crawl about in the warm waters. Suppose then that you travel to northern Maine and watch the related species of poikilotherms in the cold waters there. It would not be unreasonable to expect to see the animals in Maine moving about in slow motion compared to those in the Bahamas. In fact, however, rates of locomotion are likely to look to your eye to be more similar than different in the two places. Design experiments to assess whether the Maine animals are especially able to be active in cold waters. If you find that they are, how might their high ability for activity in cold waters be explained
Answer:
The correct answer is -
exposure of the opposite environments to the species and see if they are able to be active in cold waters.
If they are then species of organism in Maine and could have more ice-nucleating agents which are responsible for their high ability for activity in cold waters.
Explanation:
To test the assess if the Maine species of organisms are especially able to be active in cold waters an experiment can be designed where one needs to place the species or animals from Maine and Bahamas in reverse conditions.
Maine animals are placed in warm water environments and species from the Bahamas can be placed in cold water. Finding if they are able to adapt in reverse condition by calculating various processes and motion, if yes then it shows that it is not a special ability to survive in cold temps. However, if it is not then the Maine poikilotherms are specially designed for their environment. In case of yes then species of organism in Maine and could have more ice-nucleating agents

If the left primary sensory cortex were damaged along the longitudinal fissure, a person could have trouble detecting sensation in the __________. tongue left hand right foot right buccal area
Answer:
right foot
Explanation:
The primary sensory (somatosensory) cortex is a region of the brain that receives nerve signals, which is located in the anterior part of the parietal lobe. The primary sensory cortex processes somatic sensory info from receptors for pain, pressure, touch, and temperature. The primary somatosensory cortex on the left side of the brain coordinates the sensory data of the right side of the body, while the primary somatosensory cortex on the right side of the brain coordinates the sensory data of the left side of the body.

Energy is released during chemical reactions that occur in
Answer:
Mitochondria
Explanation:
Living organisms, no matter how microscopic, require energy for their metabolic activities. However, this energy is released for use in form of ATP when the organism undergo the process of cellular respiration, a metabolic process that breaks down food to release its stored energy.
However, this cellular respiration is a chemical reaction that takes place in an organelle of an eukaryotic cell called MITOCHONDRION (plu- mitochondria).

In the experiment, "Do white cats eat more than black cats?" the independent variable would be:
the color of the cat.
how much each cat weighs.
how much food each cat eats.
the temperature of the food.
In the given experiment, the independent variable would be the color of the cat. Thus, the correct option for this question is A.
What is an Independent variable?An independent variable may be defined as a type of variable that significantly and effectively stands alone and isn't changed by the other variables you are trying to measure. The independent variable is the cause. Its value is independent of other variables in your study.
According to the context of this question, the color of the cat would not depend on how much food a particular type of cat eats. This will depend on the nature and diet of the cat along with its physiology and pattern. So, the color of the cat would be thought to be the independent variable in the experiment because it does not make any sense in the eating cat.
Therefore, in the given experiment, the independent variable would be the color of the cat. Thus, the correct option for this question is A.

AMP-PNP is the abbreviation for a structural analogue of ATP in which the second and third phosphate groups are linked by an NH group (instead of an oxygen atom). AMP- PNP can bind to the ATP-binding site of most ATPases. It differs from ATP in that the
terminal phosphate cannot be removed by hydrolysis (so you cannot create ADP, therefore, you cannot get energy from AMP-PNP). Based on this information, explain the following
a. When isolated myofibrils are placed in a flask containing Ca2+ and AMP-PNP, contraction is quickly arrested. Where in the contraction cycle will contraction stop? Be specific.
b. What affects would you predict for cilia on a paramecium to which AMP-PNP is added? Be specific as to the proteins / molecules whose function would be inhibited and what would be the overall affect?
c. When researchers incubated purified vesicles, axoplasm (containing motor proteins), and MT from the giant squid axon and added AMP-PNP, the vesicles did not move along the MT. Explain this observation using specific proteins / processes affected.
Answer:
Explanation:
a.
Actin and myosin, two contractile proteins, make up myofibrils. ATPase activity is present in the myosin head. Troponin tropomyosin complex is displaced by calcium ions, exposing myosin's entire surrounding binding site on actin. Myosin heads execute the power stroke, and detachment of the head is needed for the second cycle. Myosin head detachment is aided by ATP binding & hydrolysis. Since the solution contains AMP-PNP instead of ATP, myosin heads are unable to hydrolyze and detach from myosin-binding sites on actin, thereby preventing contraction.
b.
The active ATPase correlated with both the dynein arms is found in cilia and flagella. Dynein is a motion motor protein family that walks around microtubules. The core of cilia is made up of microtubule bundles linked to the motor protein dynein. In the presence of AMP-PNP, the net reaction will be to stop the ciliary movement by inhibiting dynein motor proteins.
c.
Kinesins and Dyneins, two groups of motion motor proteins with ATPase activity, are involved in axonal transportation. All the motion motor proteins use energy from ATP hydrolysis to transfer secretory vesicles through microtubules. Since the inclusion of AMP-PNP does not supply electricity, vesicular transport does not occur.

difference between respiration and breathing
Answer:
Breathing is a physical process that involves various organs like the lungs, windpipe, nose, and others for exchanging the gases that are inhalation or taking of oxygen and expelling the carbon dioxide in the body.
Respiration is a chemical process that takes place inside of the cell by breaking the sugar using oxygen taking from breathing to produce energy. These both processes are different, however, interrelated to one another as breathing provides oxygen for respiration, and respiration gives up carbon dioxide to expel out by breathing.
