what do u mean by this chromosones contain information of inheritance of character from parent to next genration in the form of dna
Answer:
Explanation:
DNA are the building blocks of chromosome. Think about a blueprint. Blueprint contain instructions of how to build something, the actual instructions are the drawing and those drawings are housed on the blue paper.
So if you connect that analogy to this, DNA is actually the code that tells your cell how to do, what to do and such, they are actual genetic codes with bases such as Adenine, Guanine, Cytosine, and Thymine arranged in a double helix pattern. The chromosomes are the structures that are a result of arrangement of billions and billions DNA bases, thus they are the structures that house DNA and gene (part of DNA that codes for stuff)

I really need help with this one
Answer:
The prey population, the rabbits, and the predator population, the foxes, directly rely on one another. As the rabbit population grows, more food becomes available for the fox population to grow, therefore the fox population grows. The rabbit population now has more predators, but an assumed constant amount of food, causing the rabbit population to fall. The rabbit population falls and less food becomes available for the fox population, so the fox population falls. Both the predator and prey species are majorly responsible for the carrying capacities of the other species.

A species was added into a particular ecosystem to control the population of a prey species. This method of introducing a new species is called (biological augmentation) , (bioremedation) , or (reforestation). The population of the added species increased, leading to an imbalance in the ecosystem. This increase happened because (the competition for resources increased in the ecosystem) , (the population of prey species increased in the ecosystem) , or (the amount of resources increased in the ecosystem).
Answer:
A species was added into a particular ecosystem to control the population of a prey species. This method of introducing a new species is called bioremediation. The population of the added species increased, leading to an imbalance in the ecosystem. This increase happened because the competition for resources increased in the ecosystem.
Explanation:
The method of introducing a new species into an ecosystem to control the population of a prey species is called "biological augmentation" but in the given scenario, the population of the added species increased, leading to an imbalance in the ecosystem.
Biological augmentation is a method of introducing a new species into an ecosystem to control the population of a particular species that is causing problems. For example, if a particular species is overpopulating and causing damage to an ecosystem, introducing a predator or parasite that preys on that species can help control its population.

Scientists have observed unusual "benefits" of parasites in other species. This observation has led to some scientific debate regarding whether some relationships that were once considered parasitic may, in fact, be more mutualistic. Does the article support the idea of the existence of a mutualistic relationship between tapeworms and brine shrimps? Explain your answer using evidence from the text.
Answer:
Explanation:
Mutualism is a type of relationship where the organism involved both benefit from the relationship. This so true of tapeworms and shrimp as the infection caused by tapeworm on the shrimp bring about longetivity of the shrimp because it help them to survive in water containing arsenic toxins. Tapeworm lives on it host the shrimp and shrimp also benefit from tapeworm through its infection.
Answer:
No, the article doesn’t support the idea of the existence of a mutualistic relationship between tapeworms and shrimps. The article explains that it’s to the parasite’s benefit to keep the host alive, which explains why it may offer some protective benefit to the organism. The tapeworm still causes harm to the shrimp. So, the tapeworm still fits the definition of a parasite.

Answer:
c: Single-celled organisms released oxygen into the air when they photosynthesized.
Explanation:
got it right on edge. also if there were no oxygen animals and humans could not live
The event in Earth’s history that most directly allowed life to exist on land is "Single-celled organisms released oxygen into the air when they photosynthesized." Thus, the correct option is C.
What are Single-celled organisms?Single-celled organisms may be defined as those organisms that are constructed by only one cell. This single cell carries out all of the functions needed for the organism. They lack compartmentalization.
Single-celled organisms mainly bacteria evolve themselves in such a way that they released oxygen into the air when they photosynthesized. Such bacteria are known as photosynthetic bacteria.
These bacteria are only the source that brings this diversity among living entities on the earth's surface by making the availability of oxygen on this planet.

Batesian mimicry is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both. It is named after the English naturalist Henry Walter Bates, after his work on butterflies in the rainforests of Brazil.
Answer:
Mimicry
Explanation:
Mimicry can described or explained as the process whereby one organism copy the action of others and do exactly the same as that copied organism.
This is usually done when the action copied from the organism is useful in escaping from predators or being seen by other organisms as a predator and allow it to have access to the available resources.

What situation is an example of equilibrium
Answer:
Answer is the amount of water in a cup doesn't change.
Explanation:
"Equilibrium is achieved when the state of a reversible reaction of opposing forces cancel each other out. While in a state of equilibrium, the competing influences are balanced out. Imagine a cup with a hole in it being filled with water from a tap. The level of water in this cup would stay the same if the rate at which the water that flows inside is the same as the water that flows outside and thus, option C will be the correct answer."
"Equilibrium is defined as a state of balance or a stable situation where opposing forces cancel each other out and where no changes are occurring. An example of equilibrium is in economics when supply and demand are equal. An example of equilibrium is when you are calm and steady."
