Answer:
Cyclic
Explanation:
It is cyclic because as the number of predators increase in the ecosystem, the number of preys decreases with time. This decrease in preys means lesser food resources for the predators which then decreases the population of the preys. As the predators decrease the number of preys starts to recover and increase in population.
The cycle goes on and on which makes it a cyclic relationship in the nature of predator-prey dynamics in stable communities
The word that described the nature of predator-prey dynamics in stable communities is Cyclic.
What is Cyclic?It should be cyclic since the no of predators should be raised in the ecosystem also the number of prey should be decreased along with time. Here the reduction of prey represents that there are fewer food resources due to which it reduced the preys population. Also, when the predators reduced the no of preys so it begins to recover due to which the population is increased.

Imagine that all plant life on earth was suddenly wiped out. What effect would this have on the atmospheric gases and how would this ultimately affect earths climate?
Five closely related species of frogs live in ranges that overlap. Some breed in woodland ponds, some in lowland swamps, and some in streams. How do these five species of frogs remain separate and do not attempt to mate?
Answer:
The diversity within the same species is what makes it not possible to reproduce, since it can have different methods of appearance and even different zones or mechanisms of reproduction since this was adapted to each particular climax.
Explanation:
Frogs that have different qualities in the same species are because they are subject to different environmental characteristics, therefore it is a way of natural adaptation.
By having different adaptation methods, this conditions that there is no cross reproduction between them.
Cell differentiation occurs when various genes are expressed to a different extent in different cells. What does it mean for a gene to be "turned off," or not expressed?
A. Transcription into RNA does not occur for that gene.
B. That gene is removed from the cell's DNA.
C. The RNA for that gene is not translated into protein.
D. The proteins sequenced by that gene are broken down inside the cell.
Answer:
C.
Explanation:
When it is said that a gene is "turned off" this usually means that this particular gene is no longer making the directions that need to be followed in order to make proteins. Therefore the proteins that are needed for a specific job, such as tolerating lactose, are not being produced. So the answer in this question would be that the RNA for that gene is not translated into protein.
Answer:
Answer is A.Transcription into RNA does not occur for that gene.

Which of the following statements best describes the formation of volcanoes?
A.
At a transform plate boundary, the crusts slide against each other to form magma by frictional heat.
B.
At a convergent plate boundary, the oceanic crust is pulled beneath the continental crust, where magma forms and moves upward.
C.
At a divergent plate boundary, the pressure of seawater rushing into the oceanic crust rift creates a volcano.
D.
At a convergent plate boundary, the continental crust collides with another continental crust to form volcanoes.
Answer:
B). At a convergent plate boundary, the oceanic crust is pulled beneath the continental crust, where magma forms and moves upward.
Explanation:
Volcano is described as the fissure in the crust of the earth through which the molten rock, lava, or hot gases are allowed to escape from this chamber. The second option most appropriately states that 'the oceanic crust is pulled beneath the continental crust at a convergent plate boundary where the formation of magma takes place and makes it to the surface(through eruption in the form of lava).' The process can have both the creative as well as destructive impacts as it brings a lot of useful minerals that makes the soil rich and fertile while on the other hand, the ash is fatal for the environment. Thus, option B is the correct answer.
The statement which best describes the formation of volcanoes is: B. At a convergent plate boundary, the oceanic crust is pulled beneath the continental crust, where magma forms and moves upward.
A volcano can be defined as a mountain or hill that has a large circular or conical hole at the top through which volcanic ash, rock fragments, gases, dust, hot lava, steam etc., are expelled from the vent of a planetary-mass object, either at regular intervals or continuously.
A convergent plate boundary refers to a boundary where two (2) plates move towards each other, thereby, resulting in subduction or collision.
As a result of the oceanic crust being pulled beneath the continental crust at a convergent plate boundary, molten magma are formed and then moved upward as volcanoes.
In conclusion, the collision between two (2) plates as a result of subduction causes an oceanic crust to be forced underneath the mantle, thereby, forming volcanoes.

Which work against each other to maintain homeostasis?
A. Hormones and neurotransmitters
B. Motor neurons and sensory neurons
C. Somatic and autonomic nervous systems
D. Sympathetic and parasympathetic nervous systems
Answer:
D.
Explanation:
I just did this unit 5 test on ap ex, this is correct.
Sympathetic is kind of the reaction to something, like the stress or when you can't stop breathing because you're panicking.
Parasympathetic is the opposite, it calms you down after you've freaked out. Right after you've been scared like crazy, and then you see it's just your best friend, you breathe and relax because you realized it's a joke.
So these work "against" each other to maintain homeostasis and the well being and balance of your body.
PLZ mark me brainliest for explaining!
The system that works against each other to maintain homeostasis is sympathetic and parasympathetic nervous systems. The correct option is D.
What is homeostasis?Homeostasis is the state of constant internal, physical, and chemical conditions maintained by living systems in biology.
This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.
Homeostasis, derived from the Greek words for "same" and "steady," refers to any mechanism by which living things actively maintain relatively stable conditions required for survival.
Homeostasis is regulated by a series of regulatory systems functioning at the organ, tissue or cellular level.
Substrate demand, activation or inhibition of individual enzymes and receptors, enzyme synthesis and degradation, and compartmentalization are examples of control mechanisms.
The sympathetic and parasympathetic nervous systems compete with one another to maintain homeostasis.
Thus, the correct option is D.

What is most unusual about parasites
Answer: pls mark me branniest
Explanation:
It depends on its host for survival. Without a host, a parasite cannot live, grow and multiply. For this reason, it rarely kills the host, but it can spread diseases, and some of these can be fatal. Parasites, unlike predators, are usually much smaller than their host and they reproduce at a faster rate.

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:
6CO2 + 6H2O + light C6H12O6 + 6O2 C6H12O6 + 6O2 6CO2 + 6H2O + energy
How do these equations explain why the total amount of O2 and CO2 remains the same?
Answer:
During photosynthesis, to form 1 molecule of glucose, 6 molecules of CO2 is needed to be used as a reactant. 6 molecules of O2 is released as a by-product.
However, during aerobic respiration, to hydrolyse 1 molecule of glucose, you will need 6 molecules of O2 as a reactant, releasing 6 molecules of CO2 as by-product.
Essentially, the total amount of CO2 and O2 remains the same assuming the rate of aerobic respiration is the same as the rate of photosynthesis, resulting in no net gain or loss of both CO2 and O2 in the atmosphere.

What evidence does Dr. White use to describe the species Ardi as “neither a chimp, nor …human.”
Answer:
It means that the anatomical characteristics found by Dr. White, are different enough for him to affirm that what he found does not belong to the species of the Chimp or to the human being.
Explanation:
This question refers to the 4.4 million-year-old partial skeleton of Ardipithecus ramidus, which Dr. Tim White and his colleagues discovered in 1994. Upon realizing that this skeleton, possibly belonged to a primate, everyone was caught up in the research, thinking that it could be an ancestor of human beings, however, the anatomical characteristics of this skeleton, diverged greatly from those found in Chipanzé skeletons and human skeletons, which made Dr. Tim conclude that the skeleton did not belong to any of these two species and indicated a different species.

An indicator for a protein is added to a solution
that contains protein and to a solution that does
not contain protein. State one way, other than the
presence or absence of protein, that the two
solutions may differ after the indicator has been
added to both. [1]
Answer:
There would be a color change
Explanation:
Biuret solution is used to identify the presence of protein. Biuret reagent is a blue solution that, when it reacts with protein, will change color to pink-purple.
Since one of the solutions does not contain protein, the blue color of the Biuret reagent will not change.
3. If a daughter has an X-linked recessive disorder, such as color-blindness, she inherited the
trait from
a. her mother
b. her father
c. both parents
d. neither parents
Answer:
She inherited the trait from C: both parents.
Explanation:
The daughter, being female, has the chromosomes XX. Since the disorder is recessive, both of the chromosomes need to have the disorder's allele in order for it to activate. The daughter's chromosomes can be labeled as X(c)X(c); where the c stands for the color-blindness allele. She needs one X chromosome from the father, and one X chromosome from the mother. Both of these chromosomes contained the (c) allele, as said before, so the mother has one X(c) and the father has one X(c). This means that she inherited the trait from both parents. The final answer is C.
