What steps are involved when a planarian needs to generate new cells
Answer:
Using this technique, which they termed 'chemical amputation', the team induced lesions in planaria and investigated which genes were activated over the course of the regeneration process. The pharynx lacks neoblasts, but cells near the wound quickly start dividing and regenerate the amputated organ.
The steps which are involved when a planarian needs to generate new cells include the different stages of regeneration.
What is Regeneration?Regeneration in the planarians depends on the presence of stem cells called as neoblasts. These newly formed cells are distributed throughout the body and, when part of the worm has been amputated, these parts are activated to reform the tissues which have been removed.
Planarians also use this extraordinary regenerative ability to reproduce asexually. Through the process of transverse fissions, planarians which anchor their tails and also essentially pull themselves apart from each other, resulting in two fragments which include one head and one tail that will regenerate into two genetically identical worms.

Plants are autotrophs, organisms that produce their own food through the process of photosynthesis. The chemical reaction that describes photosynthesis is shown below. How does reducing the amount of light energy affect the products of photosynthesis?
Answer:
Reducing the amount of light energy also reduces the rate at which products are formed.
Explanation:
According to this question, plants due to their ability to capture light energy using their chlorophyll pigment are said to be autotrophs i.e. perform photosynthesis to obtain their food. Photosynthesis is a process that requires light energy from the sun, and it can be measured by the amount of O2 and glucose produced as PRODUCTS.
However, in a case where the amount of light energy is reduced, this means that the amount that will be captured by chlorophyll will be low, hence, reducing efficiency. This means that reducing the amount of light energy also reduces the rate at which products are formed.

What Happened to the Anchovy? - Part 2
Natural events and human activity can threaten the health of the anchovy population off
the coast of Peru. El Niño events are natural events that occur about every two to seven
years. During these events, lower air pressure over South America results in changes to
wind patterns. Normally winds blow from east to west, pushing surface water away from
the coast of Peru. During El Niño events, winds blow from west to east. This pushes
warm surface water toward Peru's coast. The warm surface water contains less oxygen
than cold water and blocks upwelling from bringing nutrients to the surface
Commercial fishing is a human activity that harvests millions of tons of anchovies each
year. In the 1970s, the fishing Industry recognized the need to protect both the
anchovies and the ocean ecosystem. As a result, the government set limits on the
amount of anchovies a fishing boat could catch each year,
The list shows the years in which El Niño events were the strongest. The graph shows

A overfishing in previous years and warm waters with few nutrients
B. movement of anchovies to other waters and fishing of large fish
C. conservation of anchovies and habitat management
D. warm winds and low-pressure areas
Note about the question:
You will find the graph in the attached files.
Answer:
A) overfishing in previous years and warm waters with few nutrients
Explanation:
Under El Niño conditions, there is a tropical stream, which is usually weak, that acquires strength while the opposite streams debilitate. This event impedes warm water to go eastward, remaining in South America´s coasts, which produces unusual precipitations in Chile followed by floral bloom in Atacama desert and fewer precipitations events in Eastsouth Asia and North Australia. During and after the El Niño, occurs a fishery crisis because there is no upwelling on the coasts of South America, nutrients from the bottom do no ascend, and fish populations remain equal or decrease.
Around 1970, there was excessive overexploitation of fishes. This overfishing probably led to a significant decrease in the anchovy population size, reducing the number of individuals in the reproductive stage, especially the females. The graph reflects that during the following years, there were also peaks in anchovy catch. The population did not have enough time to recover from the highest peak in 1970.
From 1982-1983 El Niño event was severe. No upwelling meant no nutrients to survive, and that the remaining anchovy population, previously affected by fishery, hardly made it that year. There was probably a fishery crisis, and hence, no animals were caught in 1984.
regarding the diffusion of oxygen, which of the following statements is/are true? a. oxygen diffuses rapidly into the pulmonary capillary as a result of a large driving pressure. b. an increased thickness of the diffusion barrier will limit oxygen diffusion. c. in a process called diffusion, oxygen moves from the trachea to the blood through the capillaries (tiny blood vessels) lining the alveolar walls. d. (a) and (b) are correct; (c) is incorrect e. (a), (b), and (c) are all correct
In a cycle called dissemination, oxygen moves from the alveoli to the blood through the vessels covering the alveolar walls. Once in the circulation system, oxygen gets gotten by the hemoglobin in red platelets. the correct answer is (E).
The movement of another substance has no bearing on the direction in which a substance diffuses. The medium's concentration gradient is the determining factor. as the particles advance from the region of lower concentration to higher concentration.
Diffusion is the method by which the lungs exchange gases. When compared to blood, the alveolar air has a lower concentration of carbon dioxide and a higher concentration of oxygen. As a result, carbon dioxide diffuses from the blood to the alveoli and oxygen diffuses to the blood from the alveoli.
Dissemination is vital to cells since it permits them to acquire the helpful substances they expect to get energy and develop, and allows them to dispose of byproducts. Examples of substances required by cells and associated waste products are presented in this table.

List the seven major fish body forms. For three of the seven body forms, briefly
describe how physical characteristics are related to the habitat and niche of fish
species in that category.
The seven major fish body forms are- fusiform, compressiform, anguilliform, filiform, depressiform, sagittiform, and globiform.
Below are the descriptions of the three body forms and how their physical characteristics are related to their habitat and niches:Fusiform body form: This body form has a streamlined shape that allows for easy movement through the water. It is most commonly found in open-water fish, such as tuna and mackerel, that need to move quickly to catch prey and avoid predators. Its narrow shape reduces drag, which increases its swimming speed. The fusiform body form is particularly adapted for fast swimming, and it is typically found in fish that are pelagic (live in open water).
Compressiform body form: This body form is flattened from side to side, which gives the fish a ribbon-like appearance. The compressiform body form is well adapted to moving through the water by means of quick, darting movements. They are generally found in areas of shallow water or near the bottom of the sea floor, where they can quickly move to escape danger. For example, eels use the compressiform body form to move quickly through small crevices.Anguilliform body form: This body form is characterized by a long, thin shape that allows the fish to easily move through the water.
This body form is found in fish like eels, which live in narrow spaces such as burrows, rock crevices, or coral reefs. The elongated and flexible body structure of anguilliform fish enables them to move through complex environments easily.In summary, the physical characteristics of fish are related to their habitats and niches. Each of these three body forms is adapted to different environments, from open water to rocky crevices, and each is suited to a different type of swimming or movement.

A system releases 7.9kj of heat while 6.5kj work is done on it. Calculate
A system releases 7.9kj of heat while 6.5kj work is done on it. Calculate the total change in internal energy during these operations in kJ.
Answer:14.4kJ
Explanation:
The first law of thermodynamics which states that the total change in internal energy (ΔU) of a system is the sum of the total heat (Q) released by the system to its surroundings and the total work done (W) on the system by its surrounding, can be expressed mathematically as follows:
ΔU = Q + W -------------------(i)
From the question;
Q = 7.9kJ
W = 6.5kJ
Substitute these values into equation(i) as follows;
ΔU = 7.9kJ + 6.5kJ
ΔU = 14.4kJ
Therefore, the change in internal energy is 14.4kJ
Beans and coal both have stored energy. Which of the following correctly identifies where the energy that is stored in beans and coal comes from?
The energy that is stored in beans and coal comes from the sun. Both beans and coal are products of photosynthesis, which is the process by which plants convert sunlight into chemical energy.
In the case of beans, this energy is stored in the form of carbohydrates, proteins, and fats, which can be used as fuel by animals and humans.
In the case of coal, this energy is stored in the form of carbon, which was formed from the remains of ancient plants and animals that lived millions of years ago. Over time, heat and pressure caused these remains to be transformed into the fossil fuel we know as coal. So while beans and coal may seem very different, they both owe their energy content to the same source: the sun.
In summary, the stored energy in beans and coal ultimately comes from the sun. However, the energy in beans comes directly from living plants that recently performed photosynthesis, while the energy in coal comes from ancient plant matter that has undergone geological transformations over millions of years.
