Answer:
Random variation in the population led to a population with a favorable adaptation
Explanation:
Insecticide resistance can be defined as an evolutionary process that causes a decreased susceptibility of an insect population to a particular insecticide. The evolution of the insecticide resistance occurs by the mechanism of natural selection, where most resistant insects survive and thus pass on their acquired heritable resistance to their offspring. Moreover, the evolutionary origins of the resistance trait may be associated with different processes: 1-de novo mutations (i.e., the emergence of beneficial genetic changes in the population), 2-standing variation in the original population which is selected under the selective agent (in this case, the pesticide), 3-migration of resistant specimens originally resistant to the pesticide, and 4-even interspecific transfer (i.e., horizontal transfer between different species).

What evidence partly supports the idea that the carbon in the cellulose of the tree is the same
carbon that was in the atmosphere before?
O The carbon combined with oxygen to make CO2.
O A chemical reaction occurred that converted sugar from within the tree into starch.
O The oxygen in the cellulose is the same oxygen that was in the air.
O A chemical reaction occurred in which the carbon in the atmosphere became part of a sugar molecule.
If the oxygen in the cellulose molecule found in a tree is the same oxygen that was found in the air, it can be used as evidence to support that the carbon in the cellulose is the same as the one in the atmosphere.
Carbon fixationCarbon, in the form of carbon dioxide, in the atmosphere is fixed into plant tissues as carbohydrates during the process of photosynthesis.
Oxygen is released during the process but the oxygen comes from the splitting of water.
Thus, if the oxygen found in the cellulose of a plant corresponds to the oxygen found in the atmosphere, it is an indication that the carbon in the cellulose is also the same carbon in the atmosphere.

What occurs during a solar eclipse?
Earth is closest to the Sun.
There are small tides across Earth.
The moon’s shadow falls on Earth.
The moon is covered in Earth’s shadow.
Answer:
C) The moon's shadow falls on Earth
Explanation:
I got it right on a quiz :)
During a solar eclipse the moon’s shadow falls on Earth. Hence option c is correct.
What is solar eclipse?Solar eclipse is defined as the Moon blocks some or all of the Sun's light from reaching Earth as it travels between Earth and the Sun. Eclipses of the sun happen when the moon passes in front of the earth and the sun. Earth is covered in a shadow because the moon prevents the sun's light from reaching it. If the moon fully obscures the sun, it is said to be a total solar eclipse.
When the Moon travels directly between the Sun and Earth, a solar eclipse occurs, covering Earth's surface with its shadow. The Moon's orbit doesn't quite align with the Sun and Earth, thus its shadow typically crosses the planet either above or below.
Thus, during a solar eclipse the moon’s shadow falls on Earth. Hence option c is correct.

Which of the following describes how humans can create a sustainable practice between the meat system and the green system?
Reducing the number of livestock to increase the number of crop farms
Using the waste and byproducts of livestock to help create more arable land for crops
Reducing the number of crops consumed by livestock by placing more animals in feedlots
Using the grass and seeds that are not consumed by livestock to feed nations with food scarcity
The option that describes how humans can create a sustainable system is : ( B ) Using the waste and byproducts of livestock to help create more arable land for crops
Ways to balance the meat and green systemTo balance the meat system and the green system, the systems should be interdependent on each other, that way excessive waste will be reduced and both systems will gain mutually. One way to achieve this collaboration is the use of waste products from livestock as manure to create more arable land which in turn will lead to better crop production.
Hence we can conclude that The option that describes how humans can create a sustainable system is Using the waste and byproducts of livestock to help create more arable land for crops.

Which is required for both anaerobic respiration and aerobic respiration?
oxygen
O water
O mitochondria
O glucose
Answer: Glucose
Explanation: Substrate is always required. Glucose is the substrate. Anaerobic respiration in absence of o2 and aerobic in presence of o2.
Aerobic respiration totally converts glucose into carbon dioxide and water, whereas anaerobic respiration only fully converts glucose into lactic acid or alcohol (alcohol fermentation) (lactic acid fermentation). Thus, option D is correct.
What similarity in anaerobic and aerobic respiration?The fact that glucose is used as the first molecule in both aerobic and anaerobic respiration is one of their similarities.
Additionally, both aerobic and anaerobic respiration result in the production of ATP, but aerobic respiration generates far more ATP than anaerobic respiration.
For a modest output of ATP, glucose is partially broken down in the cytosol during anaerobic respiration.
For a higher yield of ATP, aerobic respiration uses oxygen to completely break down glucose in the mitochondria.
Therefore, glucose is required for both anaerobic respiration and aerobic respiration.
