Answer:
passive
Explanation:
Observe: The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis?
Form hypothesis: Which color of light do you think will maximize the rate of photosynthesis?
Gather data: Set the Light wavelength to 400 nm. (The symbol “nm” stands for nanometers. A nanometer is a billionth of a meter.) Visible light ranges from 400 to 700 nm.
On the TABLE tab, click Record data. Then set the Light wavelength to 420 nm, and repeat. Continue recording data in the Gizmo every 20 nm until the wavelength is 700 nm.
Which colors were absorbed best by the plant?
Which colors were absorbed the worst?
If tested throughout an experiment, one would come to find that the color of light does in fact affect the rate at which photosynthesis takes place, with red and blue light being the most effective at promoting photosynthesis.
Photosynthesis is a series of chemical reactions performed by plants in order to transform light energy, in most cases being light from the sun, into molecular energy in the form of ATP molecules. Experiments have shown that the color of light to which plants are exposed can have positive or negative effects on photosynthesis rates depending on the color used.
Plants appear green to us due to the fact that they absorb all frequencies of light except green light, which is reflected. This reflection of green light serves to explain why plants show the lowest rates of photosynthesis when exposed to green-colored light. At the same time, the highest rates are when exposed to high-frequency blue or red spectrum light.

What is the relationship between wavelengths and frequency of electromagnetic waves
Answer:
The relationship among the speed of propagation, wavelength, and frequency for any wave is given by vW = fλ, so that for electromagnetic waves, c = fλ, where f is the frequency, λ is the wavelength, and c is the speed of light.

Why would the cell theory change over time?
Answer:
The invention of the microscope led to the discovery of the cell by Hooke. While looking at cork, Hooke observed box-shaped structures, which he called “cells” as they reminded him of the cells, or rooms, in monasteries. This discovery led to the development of the classical cell theory.

Mitosis
DEFINITION:
Meiosis
DEFINITION:
Answer:
Mitosis a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Explanation:
Meiosis a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
Answer :
Mitosis : Mitosis is a process of asexual reproduction observed in unicellular organisms.
Meiosis : Meiosis is the process in which a single cell divides twice to form four haploid daughter cells. These cells are the gametes – sperms in males and egg in females.

Which characteristic explains why algae blooms are more likely to grow out of control in lentic ecosystems instead of lotic ecosystems?
O Photosynthetic organisms can grow undisturbed in sunlit, nutrient-rich lentic ecosystems.
O More photosynthetic organisms are found in lentic ecosystems than in lotic ecosystems.
O Lotic ecosystems have lower nutrient and dissolved oxygen levels than lentic ecosystems.
O Lentic ecosystems have higher turbidity, which is preferred by photosynthetic organisms.
Given the characteristics of lentic ecosystems, we can conclude that algae blooms are more likely to grow out of control because photosynthetic organisms can grow undisturbed in sunlit, nutrient-rich lentic ecosystems.
Lentic ecosystems are those whose water is still. This kind of ecosystem includes bodies of water such as:
LakesPondsReservoirs SeepsPoolsand so on. These can be temporary or permanent and are found in a wide range of sizes.
Lentic ecosystems minimize the mixing of the water, allowing the water to absorb more sunlight and become warmer. Warmer water allows organisms such as algae to move easier, allowing them to float to the surface quicker and absorb more sunlight. This creates a chain reaction given that the sunlight absorbed by the algae heat the water even more, thus promoting more algae growth. For these reasons option one is correct.

Juan is visiting Costa Rica. He notices there is a lot of moisture in the air and lots of biodiversity, but the soil is thin and lacking nutrients. What type of biome is he in?
Desert
Temperate grasslands
Tropical rain forest
Tundra
Answer:
C. Tropical rain forest
Explanation:
C. Tropical rain forest
When there is a lot of moisture in the air and lots of biodiversity, but the soil is thin and lacking nutrients, this biome is a condition for tropical rain forest.The air beneath is almost always humid. The trees themselves give off water through the pores (stomata) of their leaves. Tropical rainforests are lush and warm all year long! Temperatures don't even change much between night and day.The soils in this biome are very old and low in fertility, but since there is a dry season, more of the nutrients can stay in place. In the tropical rainforest, however, rainfall is year round, and can be daily. This strips out most of the nutrients.Learn more:

what vegetable grows fast enough that you can hear it
Answer: Rhubarb
Explanation: Rhubarb Triangle. A stretch of land where the sour-sweet vegetable is cloaked in darkness and grows so fast you can hear it crack, squeak, and pop.
No vegetable develops at a rate that makes its development audible. Vegetables develop slowly taking days, weeks, or even months for any changes to become apparent.
Thus, vegetable development requires cell division, elongation, and differentiation—processes that don't produce sound. Even though certain plants, like bamboo, can grow swiftly, they do not produce audible noises while doing so.
The metaphor of "hearing" plant development emphasizes the observable changes and advancement that may be seen visually over time. The growth of vegetables is a silent process, involving biochemical and physiological changes that occur over time, without producing audible sounds.

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.
