(English )Is it correct to say that energy follows a linear flow in the food sections, while nutrients are constantly recycled? Explain.
(Portuguese) É correto afirmar que a energia segue um fluxo linear nas cadaeias alimentares, enquanto os nutrientes são constantemente reciclados? Explique.
Answer: Yes.
Responder: Sim.
Explanation: (*English) A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.
(*Portuguese) Uma cadeia alimentar é uma sequência linear de organismos através dos quais nutrientes e energia passam enquanto um organismo come outro; os níveis na cadeia alimentar são produtores, consumidores primários, consumidores de nível superior e, finalmente, decompositores.

Animal cells (like a muscle cell) that require a lot of energy probably have many _____?
A. mitochondria
B. chloroplasts
C. lysosomes
D. ribosomes
Answer:
mitochondria
it produces energy, and the cells are animal cells
Animal cells are the eukaryotic cells defined by the presence of the organelles and nucleus. The muscle cells that require a lot of energy probably have many mitochondria. Thus, option A is correct.
What is the function of mitochondria?Mitochondria is one of the major organelles that are present in large numbers in animal cells. They are majorly involved in the biochemical process for energy production and have been made of double membranes.
Muscle cells have a large number of mitochondria in their cells as they need maximum energy to perform various activities and functions. They are the powerhouse that fuels the cell by ATP production. All the cellular functions and the activities of the muscles system are regulated by the mitochondria.
Therefore, option A. mitochondria is the correct blank.

Boats are able to stay afloat because of the force caused by...
a) gravity
b) hydraulics
c) viscosity
d) buoyancy
Answer:
d) buoyancy
Explanation:
Buoyancy can be defined as an upward force which is created by the water displaced by an object.
According to Archimede's principle, it is directly proportional to the amount (weight) of water that is being displaced by an object.
Thus, the greater the amount of water an object displaces; the greater is the force of buoyancy pushing the object up.
The buoyancy of an object is given by the formula;
[tex] Fb = pgV [/tex]
[tex] But, \; V = Ah [/tex]
[tex] Hence, \; Fb = pgAh [/tex]
Where;
Fb = buoyant force of a liquid acting on an object.
g = acceleration due to gravity.
p = density of the liquid.
v = volume of the liquid displaced.
h = height of liquid (water) displaced by an object.
A = surface area of the floating object.
The unit of measurement for buoyancy is Newton (N).
Additionally, the density of a fluid is directly proportional to the buoyant force acting on it i.e as the density of a liquid decreases, buoyancy decreases and vice-versa.
Boats are able to stay afloat because of the force caused by buoyancy. This simply means that, a boat is able to float because the volume of water it displaces weigh more than its own weight. Thus, if a boat or any physical object weighs more than the volume of water it displaces, it would sink; otherwise, it floats.

Explanation:
look carefully at the diagram. state why process 2 is necessary in sexual reproduction
The process 2 is necessary in the sexual reproduction. This process is known as fertilization. This involves the fusion of both the gametes to result in the formation of a diploid zygote.
What is Fertilization?Fertilization can be defined as the union or fusion of two different gametes which include male and female gametes. During the process of fertilization, haploid sperm and egg cells fuse to form a diploid zygote for the initiation of the prenatal development. In mammals, the process of fertilization involves multiple ordered steps, such as the acrosome reaction, zona pellucida penetration, sperm and egg attachment, and the membrane fusion.
In case of normal reproduction, fertilization combines two haploid meiotic nuclei or gametes of the sperm and egg cells, and also ensures a high efficiency of the normal development and the genetic diversity in the progeny produced.

A local town has a problem with too many mice running around. In response to this they start a war on the mice, and get neighboring communities to join them. As a result, all of the mice for 40 square miles are wiped out. The town's people are very happy, hypothesize what kind of impact you think this may have on the ecosystem in this area.
Answer:
See the answer below
Explanation:
The impacts of wiping out the mice can be classified into two - positive or negative.
The positive impact resulting from wiping out the mice would be felt in terms of reduced destruction to properties, transmission of pathogens, and constituting a nuisance to the environment.
The negative impact, however, will largely be felt on the existing food chains in the community. Organisms that serve as food for the mice will experience a boost in their population as a result of reduced predation while organisms whose source of food depends on the mice will see a decline in their own population as a result of inadequate food. This might create a chain reaction that may lead to a major disruption to the food chains and the overall functioning of the ecosystem.
