Why are leaves green​

Biology
1 answer:
wolverine [178]3 years ago
8 0

Because plants cannot obtain their own food source, so they must create it using photosynthesis, and in order for that process to happen, it requires a green pigment called chlorophyll to absorb light photons and start up the process. So, leaves contain chloroplasts, which contain chlorophyll, which is green.

Blank is an inheritance pattern in which a trait is controlled by many genes?
professor190 [17]

Answer:

Polygenic inheritance.

Explanation:

Polygenic inheritance is also known as multi gene inheritance that are included in the group of non epistatic gene. The genes of the polygenic tratit are additive in nature.

More than two different genes are involved in the polygenic inheritance. This inheritance controls the trait of the organism by multiple genes. Polygenic inheritance shows the different pattern as compared with Mendelian inheritance and environment also plays an important role in the polygenic inheritance. Human skin color is controlled by seven genes and hence referred as polygenic inheritance.

Thus, the answer is polygenic inheritance.

Most of the ATP supplies for a skeletal muscle undergoing one hour of sustained exercise come from _______. A) creatine phosphat
TiliK225 [7]

Option A is correct. For skeletal muscle, there are 37 molecules of ATP produced from one Glucose-6-phosphate derived from glycogen, assuming the presence of the glycerol-3-phosphate shuttle.

<h3>How does skeletal muscle use ATP for the duration of exercise?</h3>

1. Contracting skeletal muscle is capable to use a quantity of intra- and extramuscular substrates to generate ATP at some point of exercise. These include creatine phosphate (CP), muscle glycogen, blood-borne glucose, lactate and free fatty acids (FFA), derived from either adipose tissue or intramuscular triglyceride stores.

<h3>What produces the most ATP for muscle contraction?</h3>

Aerobic respiratory produces giant amounts of ATP and is an environment friendly capability of making ATP. Up to 38 ATP molecules can be made for every glucose molecule that is damaged down. It is the desired approach of ATP production by body cells.

What does it mean for a membrane to be selectively permeable?Select two specific components of the cell membrane and explain how
saw5 [17]

Answer:

Selective transport enables the substances to move rapidly through the cell membrane (for instance, H2O, O2 and CO2), while other substances pass through the cell membrane more slowly. Moreover, there are also compounds that can't pass through this barrier.

Explanation:

The selective transport of the substances across the cell membrane enables the cell to maintain the homeostasis of the system by maintaining the ionic equilibrium on both sides of the cell membrane. Moreover, selective transport also is required for carrying out cellular mechanisms, since this mechanism enables the entry and the exit of macromolecules used by the cell to maintain its function and structure.  

The most common mechanisms of selective transport are diffusion and transport active. Endocytosis and exocytosis are active transport process where proteins, lipids, and different types of macromolecules are transported to both sides of the cell membrane through vesicles. Polar molecules (such as for instance, calcium and iron ions) may be transported via transport active, while hormones and vitamins may be transported via passive diffusion.
