Answer:
Because they are triploblastic ( Triblastica ).
Explanation:
Their body is composed of endoderm, mesoderm and ectoderm. While Cnidaria are Diblastica, so they are composed only from two layers: endoderm and ectoderm.
In addition larvae of Echinoderms are bilaterally symmetrical and they become nearly-radial only as adults.

Answer:
The last one : D
Explanation:
The diagram that represents the modelling of a full moon is : ( D ) Diagram 4
Full moonA Full moon occurs when the moon moves from its new moon position by 180°. At this new position, the sun ( light source ) ,earth and the moon forms a straight line.
During full moon the moon is completely illuminated when viewed from the Earth's position as well.
Hence we can conclude that the diagram that represents the modelling of a full moon is Diagram 4

Explanation:
pls help!!! osmosis help needed!!
Answer:
1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic
Explanation:
1. Given the image, it shows there is 10% glucose outside the cell.
2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)
3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.
2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water outside the cell than in. So, yes, osmosis will occur.
3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).
3. The cell will swell, since water is getting moved in.
6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always swell, as water moves into it.
Hopes this helps!^^ I tried the best I could at explaining.
Can anyone help me write hydroelectric essay
INTRODUCTION:
BODY:
CONCLUSION:
Please I really have bad life
Answer:
A competitive firm’s marginal revenue always equals its average revenue and price. This is because the price remains constant over varying levels of output. In a monopoly, because the price changes as the quantity sold changes, marginal revenue diminishes with each additional unit and will always be equal to or less than average revenue. A conclusion is the last paragraph of your essay, or, if you’re writing a really long essay, you might need 2 or 3 paragraphs to conclude. A conclusion typically does one of two things—or, of course, it can do both: Summarizes the argument. Some instructors expect you not to say anything new in your Hydro-power is the energy harnessed from running water-streams, rivers or any other artificial or natural water flow. It is one of the oldest method of energy production. Even in the medieval period, people used to derive energy from water wheels. The contribution of hydel power in the world energy production scenario is immense and ever-increasing.
Hydro-electricity now contributes nearly 7% of global electricity production when only 15.3 percent of the global exploitable hydro-electric potential is being used. Ever increasing awareness of ecology and social costs of hydro-plant construction failed to debar the increasing use of hydro-electricity.

Which of the following stages of photosynthesis involves carbon fixation, reduction reactions, and the ribulose 1,5-bisphosphate regeneration?
photoreduction
light-independent reaction
light-dependent reaction
first stage photosynthesis
Answer:
light-independent reaction
Explanation:
Photosynthesis, which is a unique metabolic process where plants synthesize their food (glucose) in the presence of sunlight, occurs in two stages namely: light dependent stage and light-independent stage.
The light independent stage is also known as dark stage because it does not require light to occur. It occurs in the stroma of the chloroplast where ATP and NADPH are used to fix carbon into the production of glucose. This stage involves three major processes:
- Carbon fixation of CO2
- Reduction reactions of G3P
- Regeneration of ribulose 1,5-bisphosphate (RUBP).

Explanation:
In dense forests, obtaining sunlight for plants can be tricky. Growing on the ground is not always effective for plants because there is not much sunlight hitting the ground. Orchids are epiphytes, or plants that grow on other plants. They grow on branches of trees high up in the canopy. They get more sunlight and have more access to pollinators up in the high branches. Orchids lay their roots on the bark of a tree and obtain nutrients and water from their surrounding environment.
In a short answer, identify and describe the type of symbiotic relationship between orchids and the forest trees, and explain the effect of this interaction on each species involved.
Explanation:
The symbiotic relationship between orchids and trees is called commensalism, which means the orchid and tree host depend on eachother to survive.. The orchid provides the tree with sunlight, (nutrients created by sun- exposure).
the tree provides a solid base for the orchid to climb up the tree, they are dependent on eachother for survival...
The type of symbiotic relationship between orchids and forest trees is commensalism.
What is commensalism?Commensalism is a relationship in which one species benefits while the other is neither helped nor harmed. In this case, orchids benefit from the elevated position and access to sunlight provided by the trees, while the trees are neither helped nor harmed.
The effect of this interaction on orchids is that they are able to thrive in a challenging environment where they would not otherwise survive. The effect on forest trees is neutral, as the orchids do not harm or compete with them for resources. However, the presence of orchids on the tree bark may attract pollinators or other organisms, which could potentially benefit the trees indirectly.

Answer:
Without the force of gravity from the Earth, it would just float away into space. This mix of velocity and distance from the Earth allows the Moon to always be in balance between fall and escape. If it was faster, it would escape; any slower and it would fall!

how would this affect the cells made from the cell cycle? passage: timmy has a disease that effects his cell cycle, it causes the S phase (part of interphase) to not work correctly.
Answer:
No cells are produced.
Explanation:
If the S phase of cell cycle did not work properly, the cells produced are abnormal or no cells are produced because no extra copy of chromosomes are present for cell division. If there is no extra copy of chromosomes is present in the cell, the cell will not go to the G2 phase and as a result the cell cycle is remain incomplete. So that's why we can say that no cells are produced if S phase did not work properly.
