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.

An ecosystem experiences a volcanic eruption that covers the area with lava. Which of the following organisms is most likely to be a
pioneer species in this ecosystem?
Answer:B
Explanation
to be completely honesty i have no knowledge if learning the current benefactor of the object asked in this particular question.
An ecosystem experiences a volcanic eruption that covers the area with lava. Organisms moss is most likely to be a pioneer species in this ecosystem.
What do you mean by ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes.

Which term refers to one species eating another, such as the red-tailed hawk
eating the prairie dogs?
A. Prey evasion
B. Interspecific competition
C. Predation
D. Herbivory
Answer:
Predation
Explanation:
Predation is the interaction where one organism, the predator (red-tailed hawk), kills and eats another organism, its prey (praire dog).
It is not the other three because:
Prey evasion is when the prey attempts to avoid its predator; however, in this case, the prairie dog is being eaten by the red-tailed hawk.
Interspecific competition is when individuals of different species compete for the same resources in an ecosystem.
Herbivory is the consumption of plant material by animals, and herbivores are animals adapted to eat plants. There are no plants being involved in this scenario.
What makes a variation different from an adaptation? Use an example to explain.
Here's an example of what your answer should look like. A bird has red feathers. That’s a variation. That same bird also has hollow bones. That’s an adaptation. The reason that the feathers are a variation but the hollow bones are an adaptation is because...
You come up with an example and figure out the "because" part of the answer on your own.
Answer:
A variation is different to an adaptation as a variation is a difference or variety inside a species, for example a different breed of dog such as a spaniel is a variety of the dog species, whereas an adaptation is a genetic mutation that has developed in order to help an animal survive, such as giraffes having a long neck. Adaptations continue throughout the species due to natural selection.

A young child does something he knows is wrong and immediately looks at an adult for a reaction. This child has learned to?
Answer:
This child has learned to act from its adults.
Explanation:
This child has learned to act according to the reaction of the adult. If a child done something wrong and the adult reaction is not good the child will not repeat it because he knows that this act is bad while on the other hand, when the child done something good and the adult gives a good reaction so the child will continue doing this action so we can say that a child learn most of the things from their adults.

function of the spinal cord.
A)
serves as a minor reflex center
B)
conducts motor information from the brain to various
effectors
C)
processes sensory inputs and initiates appropriate motor outputs
D)
conducts sensory information from the peripheral nervous system to the
brain
Answer:
c)
Explanation:
The central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.
What is the central nervous system?The brain and spinal cord make up the central nervous system. The brain directs our thoughts, memories, movements, and emotions. Between the brain and the nerves that run throughout the body, the spinal cord relays messages.
It regulates cognition, personality, memory, emotion, speech, and the capacity to feel and move. The corpus callosum, a band of nerve fibers in the middle of the brain, connects the left and right hemispheres of the brain.
Thus, the central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.

what are 5 functions of carbohydrates
☁️ Answer ☁️
PROVIDES INSTANT ENERGY TO THE BODY:
This appears to be the primary function of carbohydrates in the body.
Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.
RESERVE FOOD:
Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.
CARBOHYDRATES FORM OTHER BIOMOLECULES:
Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.
DETOXIFICATION OF THE BODY BY METABOLISM:
Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.
SPARING PROTEIN
In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.

2. What is the relationship between air temperature and air pressure at the
equator?
Answer:
Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure.
the pressure patterns associated with global circulation patterns. On the equator areas, since air is heated and rises, a zone of lower pressure will result.
Explanation:
mark it as brainliest. thnku hope it is helpful.
Explanation:
at the equator the air is moist and hot and when air is hot it's density decreases and so does the pressure exerted by it. and also air that contains water vapour is less denser than the air containing no or less water vapour so air containing less water vapour exerts more pressure
Suppose you have the same mass of water and air. If you want to raise the temperature of water and air from 20°C to 30°C, which substance will require more energy, Q, to do so?
Answer:
Water has a higher specific heat than air. So, it will require more energy to raise the temperature of water from 20°C to 30°C compared to what is needed to raise the temperature of the same mass of air.

Why is it advantageous for plants to respond to environmental stresses by going dormant and dropping leaves?
When they lose their leaves they need much less resources to survive (because they don’t need nutrients to support the leaves). For example trees lose their leaves in the winter because the ground freezes up and it’s harder to suck up nutrients.
