Hope it helps you.As an ecosystem goes through succession, which of the following is likely to
happen:
A. Increase in biodiversity
B. Ecosystem will trigger Secondary Succession
C. Decrease in competition
D. Decrease in niches
Answer:
A
Explanation:
succession is replacement of one ecosystem by another so this cause increase in biodiversity
When an ecosystem goes through succession, the biodiversity of the ecosystem tends to increase. Thus, the correct option is A.
What is Succession?Succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.
Succession is always taking place by a better competitor. The first arrived species is known as the Pioneer species. Intermediate species are known as seral communities, while the highest species is known as the Climax species.
Overall, it increases the biodiversity of the region.
Therefore, the correct option is A.

Tides occur in ocean,why?
Answer:
¿Qué Causa las Mareas? Podemos decir de una manera sencilla que las fuerzas de atracción que tanto el sol como la luna ejercen sobre la tierra, permiten una deformación y consecuente movimiento de las masas de agua de mares y océanos; esto hace que los niveles de agua suban y se formen las mareas.NOTA: Aquí anexo la respuesta en ingles.What Causes the Tides? We can say in a simple way that the attractive forces that both the sun and the moon exert on the earth, allow a deformation and consequent movement of the water masses of the seas and oceans; This causes the water levels to rise and tides to form.

how the consumers in one level of the pyramid obtain energy from the organisms at the previous level of the pyramid
Answer:
by feeding on the organism on the previous level, the consumers at each level will receive energy. However, most of the energy is lost at each trophic level and very little gets transferred from one trophic level to another. Approximately, 10% of the energy is transferred from one trophic level to another.
Explanation:
hence, when a level takes energy from a previous level, the engery transfers but slowly gets less, so some levels get less energy depending on where the engery was located.

describe what may happen to viruses that leave infected white blood cells
Answer:
White blood cells are an important part of the immune system. HIV infects and destroys certain white blood cells called CD4+ cells. If too many CD4+ cells are destroyed, the body can no longer defend itself against infection. The last stage of HIV infection is AIDS (acquired immunodeficiency syndrome).
what do viruses have in common with living things.
A- they are made up of specialized cells
B- they contain genetic material
C- they reproduce by mitosis
D- They contain chlorophyll
Answer:
B-They contain genetic material.
Explanation:
They are not made out of cells. They don't reproduce by mitosis(Only cells reproduce by mitosis).
Only specialized plant cells contain chlorophyll.

Imena is teaching her younger brother how to build a fire. As the fire sparks and starts to burn the kindling and wood in the fireplace, her
brother asks if the fire is alive because it is moving and growing. Imena tells her brother that the fire is not a living thing, and her brother asks
what makes something alive. What response does Imena give her brother?

For something to be alive, it has to have essential characteristics. Some non-living elements share some of these characteristics with living things, but not all of them. That is what distinguishes one from the other.
The characteristics that all living things have are:
organization; sensitivity; growth; reproduction; homeostasis; and metabolism.
As regards organization, the minimum unit of life is the cell. For something to be a living thing, it has to be a cell or have multiple cells. They have organelles and organize to perform different actions.
The following characteristic is sensitivity, which means that the thing has to react to a stimulus by giving a response.
Living things grow. In other words, they increase in size thanks to the elements that they take from the exterior and process them taking what they need to grow. To do so, they use metabolism.
Metabolism is the combination of catabolism( the elements that the organism destroys) and anabolism( the elements that the organism builds). Metabolism is also essential for homeostasis. These are the different reactions that an organism has to have a balance.
The last essential characteristic is reproduction. Living things have to reproduce themselves, there are different methods, and they depend on the type of living thing that they are.
In conclusion, fire is not a living thing because it does not have cells that can have metabolism, sensitivity, homeostasis, and it can not reproduce itself.
A living thing has six main characteristics:
organization sensitivitygrowthreproduction homeostasis metabolismEven though the fire seems like a living thing because it is consuming wood, making noises, and moving, as many living things do, it is not alive because it does not have cells. As it does not have cells, it can not have homeostasis, react to stimuli, or grow as cells do. It might look like a living thing, but it is not since it does not have the six characteristics that every living thing has.

Which would be considered a reliable source?(1 point)
an opinion column in your favorite magazine
an article from a scientific journal
a blog written by an anonymous author
a biology textbook from 1920
When looking for updated and reliable information, you always need to point to scientific journals, magazines, encyclopedias, or textbooks recently printed or published. In the exposed example, the most reliable source is an article from a scientific journal.
----------------------------------------
When looking for updated and reliable information, you need to be careful with the source, authors, and publishment dates.
In general, scientific journals, magazines, encyclopedias, or textbooks are sources of reliable information. The material exposed on these sources has been previously checked and evaluated by a group of people trained and capable to do so. If your favorite magazine is not a scientific one, you should look for another source.
You also want to consider the authors. Some researchers are very well known, and their publications probably reflect years of investigation. By looking for these authors´ publications you will ensure a good source. You should use a blog written by a well-known author, but not a blog that is written by an anonymous one.
You also need to consider that your source should be recently printed or published. Science is very dynamic and continuously changes. Discoveries always replace old information. So when looking for a reliable source, you need to look for recent publications. A biology textbook from 1990, although it is a reliable source, it probably has old information.

Which explains why secondary succession generally occurs more rapidly in an area than does primary succession?
A) Average precipitation is higher
B) Moderate climatic conditions exist
C) Pioneer species are microscopic
D) Soil formation has already occurred
Answer:
Secondary succession usually occurs faster than primary succession because the substrate is already present. In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.
