Volcanic eruptions occur when magma rises upwards through ___ to reach the ____
Volcanoes eruption when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.
When Melting takes place?Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. Volcanoes are the large volcanic buildings with long, and generally the conical shape, usually with a small crater on the summit and the steep flanks, that constructed by the interleaving of lava flows and the pyroclastic products emitted by one or more conduits.
Compound volcanoes are present in all regions of the volcanism, but it has in the plate convergence zones, where the tectonic plate subdows plunges toward the earth's mantle beneath another tectonic plate, that these volcanic buildings are the most abundant.
The magmatic expression of a converging plate margin environment is usually a series of sub-regularly spaced Compound Volcanoes, forming a sub-parallel volcanic arch to the tectonic fossa.
Therefore, Volcanic eruption when molten rock called magma rises to the surface.

O A. Parasites and disease weaken or kill a constant percentage of the rabbit population, regardless of its density.
o B. As the density of the rabbit population increases, parasites and disease weaken or kill a greater percentage of rabbits.
O
C. As the density of the rabbit population increases, parasites and disease weaken or kill a lesser percentage of rabbits.
o
D. Parasites and disease weaken or kill mostly the youngest and oldest rabbits, and not the rabbits of average age.
Answer:
The correct answer is - As the density of the rabbit population increases, parasites and disease weaken or kill a greater percentage of rabbits
Explanation:
Disease and parasitism are types of density-dependent limiting factors that affected or influenced by the change in the population density, In this case, parasitism and disease affect the population of the rabbits.
If the density of the rabbit population increases the both density depending on the limiting factors parasites and disease weaken or ill a greater numbers of rabbit population.

How do molecules in the cells of the body release energy
Explanation:
Chemical energy is stored in the bonds of sugars. When the bonds of a sugar molecule are broken, a burst of energy is released that the cell can use. Cells can release energy in two basic processes: cellular respiration and fermentation. ... In cells use oxygen to release energy stored in sugars such as glucose.

Why do bacteria numbers start to decline when treated with antibiotic C but then
begin to increase as time goes on?
15
A) Some bacteria with resistance to antibiotic C were selected for over time.
B) Additional bacteria were added to the experimental group.
18
C) Antibiotic C degraded and thus was no longer effective.
D) This is the normal course of bacterial growth no matter which antibiotic is
applied.
Answer:
The correct answer is - option A) Some bacteria with resistance to antibiotic C were selected for overtime.
Explanation:
In the given question it is stated that the bacteria number initially declines when they are treated with antibiotic C but then started to increase as time passes on. It is clear with the given data that initially the number of bacteria declines due to bacteria does not resistant to antibiotic C but after some time some bacteria developed resistance to the antibiotic and were selected and increased overtime.

Fruit production in anthophytes develops from: a. a female reproductive structure b. a male reproductive structure c. both male and female reproductive structures d. photosynthetic signals
Answer:
a. a female reproductive structure
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.
Division Antophyta are classified into two (2) main categories and these includes;
I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.
II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.
Fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.

Cell organelles are any of a number of organized or specialized structures within a living cell.
What is a cell?A cell may be defined as the fundamental structural and functional unit of living organisms. Each living organism is made of a cell. It is responsible for each metabolic function that is necessary for the survival of living entities.
Inside each living cell, a fluid jelly-like substance known as cytoplasm is filled. This provides an environment for the cell to accomplish all sorts of its task. Within the cytoplasm, a number of various organized or specialized structures are present which are known as Cell organelles.
A cell organelle may be characterized as a small structure in a cell that is surrounded by a membrane and has a specific function.

How does natural selection explain why some organisms are more likely to survive and reproduce than other organisms?
A. Some organisms inherit traits enabling them to adapt better to the environment.
B. Some organisms acquire traits during their lifetimes that they pass to their offspring.
C. Some organisms do not reproduce as many offspring during their lifetimes.
D. Some organisms die before they reproduce any offspring.
Any heritable characteristic that aids an organism in surviving and reproducing in its environment is referred to as an adaptation. Some organisms are more likely to survive and reproduce than others as some of them inherit traits enabling them to adapt better to the environment.
Why do organisms adapt?To live, all species must adapt to their surroundings. This entails adjusting to survive the ecosystem's climatic conditions, predators, and other species seeking the same food and space.
Organisms with heritable features which enable them to better adapt to their environment relative to other members of their species will be more likely to live, reproduce, and pass on more of their genes to the next generation the theory of evolution by natural selection.
Thus, the correct option is A.
