Most plant leaves contain yellow and orange carotenoids as well as green chlorophylls. Why then are most leaves greenish
Answer:
Because the leaves contain a greater concentration of green chlorophylls than yellow and orange carotenoids.
Explanation:
Chlorophyll and carotenoids are both pigments found in the cells of organisms like plants. They have differing color range depending on which wavelength of light they absorb and which they reflect. For example, chlorophyll pigment are green because they reflect green light and absorb others.
According to this question, the leaves of most plants contain yellow and orange carotenoids in addition to green chlorophylls but leaves are mostly green. This is because there is an abundant of chlorophyll pigment than any other pigment in the leaves of most plants. Hence, GREEN COLOR conferred by chlorophyll dominates and masks the color appearance of the other accessory pigments like yellow and orange carotenoids.

Why does the moon have a effect on the sea?
will give BRAINLIEST and a thank you!
Answer:
The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. ... High tides and low tides are caused by the Moon give me brainliest
contrast ionic covalent bonds. what happens to the valence electrons how does it affect the elements/compounds
Answer:
The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. ... To form a covalent bond, one electron from the halogen and one electron from another atom form a shared pair.
Write a short essay on a local natural resource that is mined in your region and the uses that come from this mineral. List ways in which the environment is affected by resource extraction.
Answer:
Gypsum and limestone.
Explanation:
Mining of valuable stones such as gypsum and limestone occur in my location. These valuable stones are used in the formation of beautiful tiles and in painting materials. Due to extraction of these valuable stones, erosion of the land occur as well as air pollution increases by the use of machines for extracting these minerals so it caused adverse affect on the environment so this mining has to be limited in order to both save the environment and get benefits from these minerals
Answer:
(Answers may vary.)I live in Utah. Copper is mined in my state. Bingham Canyon Mine is the copper mine in Utah. Copper mining has played a vital role in the economic and social development of my state.Copper is used for variety of purposes. Most electrical appliances use copper. Moreover, water pipes, weather stripping, and wires use copper. Copper is used for making automobiles, ships, airplanes, and various other materials that we use on a daily basis.Copper in Utah is mined in open pit mines. They are severely impacting the environment. The hazardous pollutants, such as lead and arsenic, emitted during the mining process are affecting the fish and wildlife habitats in the nearby areas. Apart from impacting wildlife, the mines are polluting the groundwater in our state.Copper mining in Utah has positively affected economic development in the state. However, it has negatively affected wildlife and groundwater.

3. How can diversity within an ecosystem be compromised?
O by regulating human activity within an ecosystem
O by helping to maintain habitats that have been disturbed
O by building structures on natural habitat areas
O by leaving the ecosystem alone to fend for itself
Answer:
O by building structures on natural habitat areas
Explanation:
The diversity within an ecosystem can be compromised by building structures on natural habitat areas.
An ecosystem is part of the environment made up of living and non-living components in their natural habitats.
Diversity entails variations in the life forms within a particular ecosystem. When human-induced pressure begins to impact the environment, diversity is threatened Nature has its balancing effect the allow for a wide range of organisms to thrive. When human builds structures, part of the natural habitat is lost.Answer:
building structures on natural habitat areas

What distance would be covered in 10
minutes by a train that travels at a constant
speed of 500 meters per minute?
Answer:
The correct answer would be - 5000 meter or 5 kilometers
Explanation:
Given:
Speed = 500 meter/minute
Time = 10 minutes
Distance would be covered = ?
Formula used:
speed = distance/ time
then, Distance = speed*time
Solution:
Putting values in the provided formula:
Distance = speed*time
distance = 500*10 meters
= 5000 meters or 5 kilometer (1000 meter = 1 kilometer)

What do ocean waves and
currents have to do with energy waves and
electrical currents?
Answer:
they are both waves and currents
Explanation:
gl studyinggg
Ocean waves, currents, and energy although both waves and electrical currents involve the movement of energy, they are distinct phenomena that occur in different mediums and generate electricity in different ways.
What is the significance of the ocean waves?Ocean waves are caused when the wind blows or passes over the surface of the water, which leads to the generation of larger waves and these waves transfer energy through the ocean's water, which can be used to generate electricity using wave energy converters. They are caused by a variety of factors, including differences in water temperature and salinity, the rotation of the earth, and winds etc.
Hence, ocean waves, currents, and energy although both waves and electrical currents involve the movement of energy, they are distinct phenomena that occur in different mediums and generate electricity in different ways.
