7. Pollution that is ______
will break down over time. A good example would be ______
Biodegradable / Grass clippings.
Persistent / An aluminum can.
Pollutants that is biodegradable will break down with time, for example, grass clippings.
• The wastes emerging from the households, which can be decomposed by microbes are known as the biodegradable pollutants.
• These components can be easily degraded with time by naturally occurring agents like water, oxygen, UV rays, acid rains, and microbes.
• Some of the examples of biodegradable pollutants are wastes products from animal and humans waste, dried leaves, plant products, grass, flowers, and fruits.
Thus, biodegradable pollutants get dissociate with time, and one of the example is grass clippings.

Which of the following statements about secondary consumers is false?
a. reproduce more slowly than primary consumers
b. are larger than primary consumers
c. are smaller than tertiary consumers
d. could be more regerred to as "carnivoires"
e. are more numerous than primary consumers
Answer:
e
Explanation:
The correct answer would be that they are more numerous than primary consumers.
Secondary consumers are never more numerous than primary consumers. This is primarily due to the fact that the higher we move up the food chain, the less efficient the amount of energy derived from food. Up to 90% of energy is sometimes lost at each trophic level as we up. Due to this inefficiency, the available food at top consumer levels can only support a few organisms. Hence, the higher we move up the food chain, the lesser the number of organisms the available food can support.
The correct option is e.

Which complex carbohydrate contains only a-1,4-glycosidic linkages?
Answer: Amylose
Explanation: Which complex carbohydrate contains only a-1,4-glycosidic linkages? Amylose (Amylose is formed from a-1,4-glycosidic linkages of glucose.)
Amylose has α 1 ⟶ 4 α glycosidic linkage, besides this carbohydrate, all other carbohydrates have β 1 ⟶ 4 glycosidic linkages.
What is a Glycosidic bond?A Glycosidic bond is the type of linkage that occurs between two or more sugar molecules. It is formed between the hemiacetal or hemiketal group of one saccharide and the hydroxyl group of another saccharide.
The compound has a glycosidic bond known as a glycoside.
Two types of glycosidic bonds are observed such as 1,4 alpha and 1,4 beta glycosidic bonds.
The 1,4 alpha glycosidic bond is named when the OH on the carbon-1 is below the glucose ring, while the 1,4 beta glycosidic bond is formed when the OH is above the plane of a glucose ring.
Amylose has been the compound that contains only alpha 1, 4 glycosidic linkages.

How are carrying capacity, ecosystems, and biodiversity interrelated with one another?
Help pleasee!!!
The ecosystem, biodiversity, and carrying capacity are interrelated as everything is related to the living diversity present in an ecosystem.
What is an ecosystem?An ecosystem is a group of living things that communicate with one another. It is the geographic area that contains plants, animals, and other biotic and abiotic factors.
The quantity of biodiversity that can be sustained in a region is known as its carrying capacity. An ecosystem is a group of living things that communicate with one another. The biodiversity of plant and animal species is known as its biodiversity.
A space's carrying capacity reveals how long and how much of an ecosystem it can support, which in turn reveals how much biodiversity is possible.
Thus, because everything is connected to the living diversity present in an ecosystem, the ecology, biodiversity, and carrying capacity are all interconnected.

A. mitochondria, cell membrane, and chloroplasts.
B. a cell membrane, cytoplasm, and nucleus.
C a cell membrane, cell wall, and nucleus.
D. mitochondria, a cell wall, and chloroplasts.
Both plant and animal cells contain a cell membrane, cytoplasm and nucleus because animal cell does not contain cell wall and plant cell have cell wall but both of the cell contain cell membrane, cytoplam and nucleus.Thus option B is correct.
What is the difference between plant and animal cell?Plant cell consist cell wall but in animal cell, cell wall is absent. Nucleus is present in both of the cell. animal cell does not contain cell wall and plant cell have cell wall but both of the cell contain cell membrane, cytoplam and nucleus.
The main function of vacuoles present in plant cell as it help in storage of waste materials in a plant cell and maintain a proper pressure in a plant cell.
Both plant and animal cells contain a cell membrane, cytoplasm and nucleus because animal cell does not cotain cell wall and plant cell have cell wall but both of the cell contain cell membrane, cytoplam and nucleus.Thus option B is correct.
There are various differences are found in plant and animal cell. The very first difference is shape of the cell, plant cell is square or rectangular in shape but animal shape is irregular in shape.
