Answer:
C It moves in an orbit around Jupiter.
Explanation:
A moon is a natural satellite of some planet and is recognized as the star that circulates around a main planet, that is, does not orbit around a star, that is, to be considered moon, the star must move in a orbit around a planet. Some moons are larger than some major planets, such as Ganymede and Titan, natural satellites of Jupiter and Saturn, respectively, which are larger than Mercury. Thus, if the orbit of these moons were around the Sun, they could be considered as planets, but their orbits are around the planet Jupiter or Saturn, so they are considered moons.

Anna waters her plants with salty water to help them grow better. Is her thinking correct?
No. The salt will interfere with absorption of water and the plants will die.
No. The salt will cause the water to diffuse out of the plants and they will wilt.
Yes. Salt will increase the water uptake of the plant.
Yes. Salt will provide the plant with sodium and chloride ions.
Anna's assumption that salty water helps plants grow better is incorrect. High salinity in watering water can cause dehydration and toxicity in plants, resulting in wilting or death. While some specialized plants can tolerate high salinity, it poses serious osmotic stress for most plants.
No, Anna's thinking is not correct. Watering plants with salty water can have detrimental effects on their growth and survival. Salinity in the water creates an osmotic effect that can cause water to diffuse out of the plants, leading to wilting and death. This is due to the plants' inability to absorb water efficiently when competing with high salt concentrations. Consequently, salt does not necessarily increase water uptake in plants but rather creates osmotic stress, posing a threat to their well-being.
In high-salt conditions, two main problems arise for plants: osmotic stress and the accumulation of toxic ions. The osmotic problem emerges as the soil's salt concentrations escalate, making it difficult for plants to obtain water, evoking a state of drought stress. Additionally, toxic ion accumulation occurs when saline levels are high, leading to detrimental effects on the cells, and potentially plant death if the salts are not efficiently excluded or sequestered.
Some plants have developed mechanisms to excrete sodium or sequester it in vacuoles to cope with saline conditions. There are specialized plants, known as halophytes, that have adaptations enabling them to survive in high salt environments. However, these are exceptions rather than the norm. For most plants, exposure to high salinity can lead to deleterious outcomes and negatively impact their growth and development.

gas
Final answer:
Neutrons are found in the nucleus and have a neutral charge. The proton has a positive charge, while the electron is negatively charged. Liquids allow particles to move somewhat freely, and gases have particles that are the least attracted to each other.
Explanation:
Neutrons are found in the nucleus and have neutral charge. Therefore, the correct answer is that neutrons are found in the nucleus with a neutral charge.
The particle with a positive charge is the proton. Protons are constituents of the nucleus and carry a positive electric charge.
The particle with a negative charge is the electron. Electrons orbit the nucleus and are negatively charged.
In the state of matter where particles move somewhat freely but not enough to fill the entire space of a container, the correct answer is liquid. Unlike solids, whose particles vibrate but do not move from place to place, particles in a liquid can move around each other, although they are still attracted enough to stay together.
Particles are the least attracted to each other in the gas state of matter, allowing them to fill the entire space of a container.

Which of the following is not true concerning the flow of energy through an ecosystem? a. Most solar energy is used in photosynthesis. b. Photosynthesis and cellular respiration are performed by plants. c. Not all solar energy is used for photosynthesis. d. Most of the energy from photosynthesis flows out as heat.
Answer;
D. Most of the energy from photosynthesis flows out as heat
Explanation;
Energy flow is the amount of energy that moves through a food chain in a given ecosystem.
Producers such as green plants in a ecosystem convert energy from the the sun into carbon bonds, such as those found in the sugar glucose through the process of photosynthesis.
The amount of chemical energy storied as nutrients in the bodies and wastes of organisms flows through ecosystems from one trophic level to the next and through this flow energy also is lost as heat. And the chemical energy available to the succeeding feeding level decreases.

Remoras, or scker fish, attach themselves to sharks and travel with them. When the sharks feed, the remora detach themselves and feed on pieces of fish the sharks left behind. What two types of interactions are described in this scenario?
a.
Predation and commensalism
b.
Predation and mutualism
c.
Competition and parasitism
d.
Competition and commensalism
The right option is; a. Predation and commensalism
Predation is an interaction between organisms in which one organism (the predator) benefits from another organism (the prey), while commensalism is also an interaction between organisms of different species in which one species benefits from the other without either harming or benefiting the latter. From the question, the remoras benefits from the relationship by living on sharks and feeding on the leftovers of the sharks, but the sharks are not affected in any way. The relationship describes predation and commensalism.
Compare the energy conversions in lactic acid fermentation to those in cellular respiration. Considering the differences in ATP production, why would a cell undergo lactic acid fermentation?
Answer:
2 ATPs are produced in fermentation and 38 ATPs are produced in cellular respiration
Explanation:
A cell undergo lactic acid fermentation only when there is no oxygen i.e anaerobic condition only. This usually happens when a person do rigorous exercise and the oxygen demand escalate suddenly which is unmet by normal respiration process.
In fermentation, carbohydrates such as starch or sugar convert into lactic acid or alcohol in the absence of oxygen with production of 2 ATP while in cellular (aerobic respiration) nearly 38 ATPs are produced

Marine animals are impacted by ocean plastic because
Marine animals are impacted by ocean plastic because it can lead to entanglement, ingestion, and the spread of toxins, which can cause injury, illness, and even death.
Ocean plastic poses a significant threat to marine animals through several mechanisms:
1. Entanglement:
Marine animals, such as seals, turtles, and whales, can become entangled in plastic debris like fishing nets, six-pack rings, and packing straps. This can restrict their movement, leading to injury, impaired feeding, and increased vulnerability to predators. In some cases, entanglement can be fatal.2. Ingestion:
Many marine species mistake plastic debris for food. When ingested, plastic can cause internal blockages and lacerations, leading to starvation, reduced fertility, and death. Smaller pieces of plastic, known as microplastics, are particularly problematic as they can be ingested by a wide range of organisms, from plankton to large fish, and can accumulate in the food chain.3. Chemical Contamination:
Plastics often contain additives such as phthalates, bisphenol A (BPA), which can leach into the water and be absorbed by marine life. Additionally, plastics can adsorb persistent organic pollutants (POPs) from seawater. These chemicals can disrupt endocrine systems, affect growth and reproduction, and increase the risk of disease.4. Spread of Invasive Species:
Plastic debris can act as a raft, transporting species to non-native environments. This can lead to the introduction of invasive species that can outcompete native species, disrupt ecosystems, and lead to biodiversity loss.5. Habitat Disruption:
Large pieces of plastic can damage sensitive habitats like coral reefs and seagrass beds, which are crucial for the survival of many marine species.

DFG and JKL are complementary angels. m DFG=x+2,and mJKL=x-4. Find the measure of each angle
Answer:
DFG = 48°.
JKL = 42°.
Explanation:
DFG and JKL are the complementary angles.
Complementary angles may be defined as the angles that has the sum of 90°.
∠DFG + ∠ JKL = 90°.
∠DFG = x+2 and ∠ JKL = x-4.
x+2 + x-4 = 90°
2x- 2 = 90°
x = 46°.
DFG = x+2 = 46+ 2 = 48 °.
JKL = x-4 = 46-4 = 42°.
Thus the answer is DFG = 48 and JKL = 42°.
The chemical that promotes phototropism is _____.
-auxin
-gibberellin
-cytokinin
-abscisic acid (ABA)
The chemical that promotes phototropism is auxin, which is essential for cell elongation, allowing plants to bend towards light for optimal photosynthesis.
The chemical that promotes phototropism is auxin. Auxins are plant hormones that play a crucial role in facilitating the elongation of cells, which is a key process in phototropic responses. In plants, phototropism is the bending towards light, allowing plants to maximize their light exposure for photosynthesis. Auxin accumulates on the shady side of a plant, promoting cell expansion and resulting in the bending of the plant toward the light. This process is essential not only for phototropism but also affects gravitropism, apical dominance, and root growth.
Auxins, such as indoleacetic acid (IAA), are found in actively growing parts of the plant. They are integral to plant responses to environmental changes, development, and growth. These hormones are also used in commercial applications, such as promoting the synchronization of fruit setting in crop production.
Local topography and sea surface temperature contribute to differences in climate between various localities.
