Which component of roots is a differentiating region?
A. Stele
B. Cork
Answer:
if im mistaken, is it not apical meristem?
A. Stele
Explanation:
The stele is located in the region of differentiation. "It is found at the center of the root, bound by the pericycle. It contains the vascular tissues, xylem, phloem, and cambium."
Cork and apical meristems are undifferentiation and responsible for primary and secondary growth respectively.

Energy flow within a system that contains life is necessary. Scientists have explored this idea in projects such as Biosphere 2 and conducted studies about the possibility of colonizing Mars. How might research on the flow of matter and energy through ecosystems be helpful to creating a colony on Mars?
Answer:
Energy flow is integral to any biological environment that supports life. Since energy can neither be created nor destroyed, it has to change from one form to another in order to maintain a balance. Everything within an ecosystem is interconnected, from plants as producers to herbivores that feed on the plants and the predators that feed on the herbivores. All of this will have to be established de novo at Mars using artificial means because the Mars atmosphere cannot naturally do this.

What would happen if the tubing with the yellow band was placed in a beaker of distilled water?
Answer:
the distilled water to enter the tubing
Explanation:
This question is impossible to answer without knowing exactly what is in the yellow tubing, regardless we can assume that the solution in the tubing with the yellow band is more concentrated than distilled water. This being the case then this will cause the distilled water to enter the tubing due to it being hypotonic to the solution within the tubing which means it has a higher concentration of water.
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.
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.

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.

Answer: Can result in a new variety of gene combinations in the species.
Explanation:
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.

The continents' shapes fit together well, but each continent has completely different fossils.
C.

D.
The continents' shapes fit together well, and some continents have the same fossils.
Answer:
D) The continents' shapes fit together well, and some continents have the same fossils.
Explanation:
Study Island
The continents' shapes fit together well, and some continents have the same fossils. Therefore, option D is correct.
What is Pangea's theory?Pangaea Wegener was of the opinion that the planet's continents were once a single, massive landmass known as Pangaea. Wegener, an astronomer by training, described Pangaea and continental drift using biology, botany, and geology.
Pangea is significant because it formerly linked all the continents, enabling animal migration between continents that is currently impractical. As a result, various species and distinct climates evolved.
Later it was discovered that the rock formations of western Europe, northern Africa, and eastern North America all shared a similar ancestor and that they coevolved with the existence of Gondwanaland. The continent's shapes fit together well, and some continents have the same fossils. Together, these findings provided evidence for Pangea's existence. Hence, option D is correct.

If you wanted to persuade someone that tiger poaching is wrong, do you think written,spoken or visual message might be most effective? Why?
The most effective way to convince someone that tiger poaching is unethical can be through visual communication.
What is Visual communication?Because they can rapidly and clearly convey complex ideas and facts, visual communications can have a significant impact on people's feelings and attitudes toward a given topic. His images and films of tigers in their natural habitat can be used to convey the dire effects of tiger poaching, such as the extinction of tiger populations and the destruction of their ecosystems in the case of tiger poaching.
Additionally, visual communication can be used to inform people about the value of tigers in the environment, the consequences of their extinction, and the efforts of conservationists and organizations to protect these creatures.
Therefore, the most effective way to convince someone that tiger poaching is unethical can be through visual communication.

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:
