The brightness of light is related to intensity or the amount of light an object emits or reflects.
What is brightness?Brightness depends on light wave amplitude, the height of light waves. Brightness is also somewhat influenced by wavelength.
When a source appears to be reflecting or radiating light, it is said to be bright. It's critical to comprehend the terminology and technology utilized in the lighting sector.
Lumens are a unit of measurement for light output from a bulb. A light's lumen count indicates its brightness; a lower lumen count indicates a dimmer light. Weight is like bananas, To milk are gallons, Lumens enable you to purchase the desired amount of light.
Therefore, The brightness of light is related to intensity or the amount of light an object emits or reflects.

The model that shows the positions of the Sun, Moon, and Earth that have the greatest effect on ocean tides is the spring tide model.
What happen during the spring season?During spring tides, the Sun, Moon, and Earth are in alignment, which causes the gravitational pull of the Sun and Moon to reinforce each other, leading to higher high tides and lower low tides.
Spring tides occur twice a month, during the new moon phase and the full moon phase.
In contrast, neap tides occur when the Sun, Moon, and Earth form a right angle, which causes the gravitational pull of the Sun and Moon to counteract each other.
This leads to lower high tides and higher low tides. Neap tides also occur twice a month, during the first and third quarter moon phases.
It's important to note that the positions of the Sun, Moon, and Earth aren't the only factors that affect ocean tides. Other factors, such as the shape of the coastline and the depth of the ocean floor, can also influence the height and timing of tides in a particular area.

the presence of a lophophore in a newly discovered species would suggest that the species ________.
Answer: the answer is has an exoskeleton
The lophophore is the feeding organelle in aquatic organisms. Its presence in a species suggests that the species is a suspension feeder. Thus, option D is correct.
What are lophophores?
Lophophores are the feeding organelles present in the marine invertebrates like Brachiopoda, Hyolitha, etc., of the Lophophorata group. They are used for respiration, brooding, and collecting food.
Suspension feeders use these lophophores to collect and feed on the suspended organic matter and particles in the water. Lophophorates are a major example of suspension feeders.
Therefore, the presence of the lophophores suggests the species to be a suspension feeder.

briefly describe the nebula theory formation of our solar system use the words protostar and protoplanets in your discussion
Answer:
Below!
Explanation:
Currently the best theory is the Nebular Theory. This states that the solar system developed out of an interstellar cloud of dust and gas, called a nebula. This theory best accounts for the objects we currently find in the Solar System and the distribution of these objects. The Nebular Theory would have started with a cloud of gas and dust, most likely left over from a previous supernova. The nebula started to collapse and condense; this collapsing process continued for some time. The Sun-to-be collected most of the mass in the nebula’s center, forming a Protostar.
A protostar is an object in which no nuclear fusion has occurred, unlike a star that is undergoing nuclear fusion. A protostar becomes a star when nuclear fusion begins. Most likely the next step was that the nebula flattened into a disk called the Protoplanetary Disk; planets eventually formed from and in this disk.
Three processes occurred with the nebular collapse:
Temperatures continued to increase The solar nebula spun faster and faster The solar nebula disk flattenedThe orderly motions of the solar system today are a direct result of the solar system’s beginnings in a spinning, flattened cloud of gas and dust.

Why does crab grass do so well when ordinary grass struggles in late summer? Is this a phenomenon ? Or is this based on a scientific principles, what is it that causes crab grass to thrive in relation to the different type of plants ?
Crab grass does so well when ordinary grass struggles in late summer
because its seed germination is higher when exposed to hotter
temperatures.
The seeds of crab grass are mostly dormant and their germination is
dependent on the soil temperature. During summer, the temperature of the
soil is usually higher which aids its growth .
This therefore explains the reason why crab grass does well than ordinary
grass in late summer periods.

II. Apply (what you already know)
7. Sketch a model of typical plant cell and identify the mitochondria and chloroplasts.
8. What will happen to plants that are kept in the dark?
Plants will die since plants need daylight to deliver food. If there is no admittance to sunlight, the Light Dependent response will not happen.
9. What will happen if you forget to water your plants?
The plants will die since water is a necessary reactant photosynthesis.
10. What happens to animals that are deprived of oxygen?
Those animals will not be able to perform cellular respiration.
III. Big Ideas
11. One hypothesis regarding the extinction of dinosaurs is that a meteor hit the earth causing an explosion so powerful that dust blocked out the sun. Consider the model above and explain why would this have caused a mass extinction?
Obstructing the Sun would cause the powerlessness for essential makers, for example, plants, to go through photosynthesis, in this way not creating its own food fundamental for development and energy.
12. When you walk your dog, you are using energy from the sunlight to power this activity.
Explain. Sunlight gives the energy to essential makers to make their own food, using the carbon dioxide and delivering oxygen gas as a result of photosynthesis. The oxygen that is delivered into the environment is taken in by life forms as a reactant in respiration. Oxygen allows for ATP creation. The ATP is the substance energy structure that is needed to convey all cell processes such as walking your dog.
