Third option is the keeping a nanny, who will take care of their needs for the designated time everyday.
9. They need take more interest in what their children are studying at school, help with their homework and projects etc.
10. Parents should take into consideration the needs of the child and how responsible that particular childcare facility would be at delivering it.

What is the function of ATP? *
Answer:
ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus.
Explanation:
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.

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.

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.

How does the paradise flycatcher protect its young from predators? It wraps its wings around its chicks. It puffs out its feathers to look bigger. It builds a camouflaged nest. It builds an underground burrow.
Answer:
It builds a camouflaged nest.
Paradise flycatcher is a bird which can protect the young from predators. It builds a camouflaged nest.
The paradise flycatcher cannot protect the young ones from predators by wrapping its wings around the chicks, nor by puffing the feathers to look bigger, and does not build an underground burrow. Paradise flycatcher can protect the bird by camouflaging its nest. The material used for camouflaging a nest is different from the conventional material used for making nest by other birds like soft grass, spider web, animal hair, lichen, and leaves. Predators are not able to identify the flycatcher nest to be a bird nest this helps in protection of young ones.Learn more about predator:

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.

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.
