Answer:
Oxygen or Minerals or Sugars (Oxygen is the most relevant one)
Explanation:
To survive, every cell must have a constant supply of vital substances such as sugar, minerals, and oxygen, and dispose of waste products, all carried back and forth by the blood cells. Without these substances, cells would die in a very short period of time.
Answer:
Energy Metabolism
Explanation:
In order to a living cell you need to be able to reproduce, have energy metabolism, etc.
<span>When the lid for a vat
of wine is slightly open, the yeast inside can continue to perform alcoholic
fermentation because the carbon dioxide produced by the yeast during
fermentation will act as a blanket over the wine. Nevertheless, the air around the fermenter
must be still and enough carbon dioxide should be produced to continue
alcoholic fermentation. However, at some point, carbon dioxide will fall and
can no longer protect the wine. This is the right time to get your wine covered
before it will be vulnerable to undesirable microorganisms. </span>
Therefore, open fermentation
is good in the early stages of fermentation because yeast need oxygen to synthesize sterols and assimilate
fatty acids to ensure the nutrients it needs to multiply and ferment the 70% of the sugar from the fruit. Furthermore,
the yeast is responsible in decomposing sugar from the grapes into alcohol and
carbon dioxide.
Answer:
A) habitat fragmentation makes it easier for cowbird parasitism to occur
Explanation:
It is a situation where by there is transformation of a large habitat into smaller patches with smaller total area secluded from one another by a habitat different from the initial one.
Habitat fragmentation can be caused due geological processes which distort the physical environment. It is also casued by human activities which could lead to loss or extinction of certain species.
Habitat fragmentation could possibly lead to loss of habitat and biodiversity.
Answer:
The correct answer is option C. "Longer beaks allow the birds to better access seeds in bird feeders".
Explanation:
Since climate change makes more difficult for "<em>Parus major</em>" birds to feed from its primary source of food in gardens, the birds are adapting to access their second source of food, which is the bird feeder. Longer beaks allow the birds to better access seeds in bird feeders, therefore, the birds are developing longer beaks in order to adapt to their new conditions.
