There are two main processes of glacial erosion<span>. The first is plucking, which is defined as the </span>erosion<span> and transport of large chunks of rocks. As a </span>glacier<span> moves over the landscape, water melts below the </span>glacier<span> and seeps into cracks within the underlying bedrock.</span>

Read the passage “ a river for everyone”, then answer two questions below.( the entire passage is in the image above)
Anna007 [38]

Answer:

1. Moving the facilities such as crops, lawns, golf courses, and sewers etc would be unrealistic to change because many of the owners would not comprise (costs so much already), yet there are solutions. For example, the town can restrict farmers from poluting the rivers with pesticides as well as fining them and the house developments golf courses and land owners in which the money can be used towards the filteration cost. Another idea would to build cheaper wells to soak up water from different river locations or build barriers around settlements from the river. Another idea would to simply grow natural filters such as using the trees and soil they already had.

2. Of course their are limits such as costs, and figuring out the landscapes of where to build wells, add soil and trees (trees take time to grow) and more that would need plan of action from community leaders in which the people would need to speak with the advisors or the management of the buildings nearby. Without clean water people will get sick or die, and building managers need healthy people to live in their houses and work and grow crops so they'll have to make change.

<h2>Diatoms</h2>

Explanation:

  • Diatoms are one of the most important and abundant components of marine phytoplankton with two valves (frustules) composed mainly of silica (SiO2). Average size is 10-100µm
  • Inhabit all aquatic environments. They occur in the body of the water as plankton or on the bottom where they may be attached to plants or rocks or sand particles or maybe free-living and able to move between particles of the substratum. In the open ocean, they live only in the upper 200 m of the surface water.  
  • Diatoms produce an estimated 20% to 25% photosynthesis on the planet .
  • Hence, diatoms are correct answer this is because the primary producer it must be resistant to physical damage from wave action

4.4-1 Anaerobic Respiration
Vesna [10]

For lactic acid fermentation, the correct options are:

  • pyruvate
  • hydrogen
  • NADH
  • lactic acid
  • Lactic acid
  • pyruvate
  • mitochondria

For ethanol fermentation, the correct options are:

  • pyruvate
  • CO₂
  • acetyl CoA
  • acetyl CoA
  • acetaldehyde
  • Acetaldehyde
  • hydrogen
  • NADH
  • ethanol

<h3>What is a anaerobic respiration?</h3>

Anaerobic respiration is respiration which occurs in the absence of oxygen.

Oxygen is used as an electron acceptor during respiration. However, when oxygen is absent or insufficient, other molecules are used as electron acceptors in order to produce energy.

Anaerobic respiration in large organisms may result in the formation of lactate known as lactic acid fermentation.

In lactic acid fermentation, after glycolysis, the two pyruvate molecules receive hydrogen atoms from NADH creating lactic acid. Lactic acid can be converted back into pyruvate in the liver. The pyruvate can then enter into the mitochondria and cellular respiration, can proceed.

On the other hand, anaerobic respiration in microorganisms produce ethanol and is known as ethanol fermentation.

After glycolysis, the two pyruvate molecules lose a CO₂ atom, creating acetyl CoA. The acetyl CoA atom combines with hydrogen to form acetaldehyde. Acetaldehyde receives a hydrogen atom from NADH, resulting in the production of ethanol.

In conclusion, anaerobic respiration can occur either as a lactate fermentation or ethanol fermentation.

During photosynthesis, plants use _____ to make sugars and starches.
AysviL [449]

Answer;

Carbon dioxide, water and light energy;

Explanation;

-Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves.

-Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy by the process of cellular respiration and may also be used to make other substances like cellulose and starch.
