What is cognition?The mental action or process of obtaining psychological features and apprehension through self-satisfaction, experience, and the senses is the definition of cognition.
Cognitive psychologists are interested in the investigation of mental functions. This relates to the study of cognition, memory, learning, and problem-solving processes in people. Cognitive psychologists are interested in how people think or react psychologically to various situations.
On the other side, behavioral psychologists are interested in researching and observing behavior. It is additional research on the interactions between stimulants and outcomes.
Therefore, the statement is true about cognition.

Natural selection and selective breeding can cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason, selective breeding is sometimes called artificial selection.

Exoplanets
Explanation:
Exoplanets (also known as extrasolar planet) are other planets outside the solar system. Exoplanets are of different categories, some of them orbit around other stars while some called rogue planets orbit the galactic center.
There are more than 4000 exoplanets which have been discovered, these planets have been discovered using the process of Transit photometry and Doppler spectroscopy.
Sea otters regulate the presence of the sea urchins and thus, kelp is regulated for all organisms in the ecosystem. They help to keep enough kelp for other wildlife to feed on. Also, due to their ability to absorb carbon dioxide, the kelp aid in mitigating climatic change and also reduce erosion by reducing the speed of water at the coast.However, if there were too many sea urchins and no sea otter to regulate their production, the kelp would reduce and thus with no food in the ecosystem, it would collapse. As a result, the sea otter protects the kelp forests by checking the local sea urchin population. The sea otter is an example of a
Answers
Answer:
keystone species
Explanation:
The sea otter is an example of a keystone species in the scenario.
A keystone species is an organism that has a significant influence on the functioning of the entire ecosystem. Without this species, the ecosystem would either cease to exist in total or entirely different in structure. In other words, a keystone species is a fastener that holds the ecosystem together.
In this case, the sea otter indirectly regulates kelp for all organisms in the ecosystem by directly regulating the presence of sea urchins. Without kelps, several ecosystem functions such as climate change mitigation and erosion reduction would cease. Thus, the sea otter is playing a significant role as a keystone species.
An archer shot a 0.06 kg arrow at a target the arrow accelerated at 5,000 m/s squared to reach a speed of 50.0 m/s as it is left the bow.During this acceleration what was the net force to the nearest newton?
Answers
Answer:
the net force to the nearest newton is 300 N
Explanation:
The computation of the net force to the nearest newton is shown below:
According to the newton second law of motion, the force is proportional directly to the change rate in momentum
So,
Resulted force = mass × acceleration
F = 0.06 kg × 5,000 m/s
= 300 N
Hence, the net force to the nearest newton is 300 N
Answer:
300 N

Note:

Answer:
(i) Because they share the same genera, Vespula.
(ii) Because Morphologically, insects 1 and 2 are more alike than insect 3.
Explanation:
(i) Explain how the binomial names indicate that insects 1 and 2 are more closely related.
In taxonomy, many categories are used to aggregate organisms according to their evolutive relationship. These are Domain, Kindom, Clase, Order, Family, Genera, Species, Subspecies. All species might be recognized by their common name and their scientific name, which is more reliable. The binomial names of living beings indicate the scientific name by which the organisms can be recognized. A species scientific name is composed of two parts:
- Generic name or genera: correspond to many species that share common characteristics. In the example, Vespula is the genera
- Specific epithet: useful to identify each species in particular and differentiate organisms that are included in the same superior taxes. In the example, flavopilosa and rufa are the epithets that differentiate one species from the other.
According to this, we might assume that species 1 and 2 are more closely related because they share the same genera: Vespula. This suggests that they share more characteristics in common with each other than with Callicera.
(ii) Explain how the appearance of the three insects suggests that insects 1 and 2 are more closely related.
Morphologically, insects 1 and 2 are more alike than insect 3. Traits such as body shape, pigmentation pattern, antenna, wings, total body size, among others, are very similar in species 1 and 2. On contrary, species 3 is smaller, with a thinner antenna, different pigmentation patterns, different wings size and shape.

Negative adaptations will become more common in a population is NOT a principle of evolution.
what is population ?A discrete accumulation identifiable characteristics such as people, animals with the objective of analysis and data collection is called a population.
A population consists of a same group of species who reside in a particular geographical place with their reproductive capacity to interbreed.
In a population Not all individuals are able to survive and reproduce due to genetic variations in them, a local population is restricted to a smaller area or can occupy a larger area, making up for the entire species.
