Explanation:

<u>A.light intensity</u>

<u />

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen

At the compensation point, the rate of CO2 production by respiration matches the rate of CO2 utilization in photosynthesis- there is no net CO2 production . Since photosynthesis is rate limited, the rate of energy intake can be reduced in order to reach the compensation point; lowering the light intensity would slow the rate of photolysis and thus photosynthesis. Similarly, an increase in light intensity

  • increases the rate of photosynthesis- the CO2 level would be reduced as more inorganic CO2 is fixed, together with producing O2 as waste.
  • would increase the temperature of the environment- light energy is converted to heat energy which increases temperature.
  • lead to higher levels of humidity- the heightened temperature increases the rate of evaporation of water from tissues, and thus increases the humidity (water vapor content of the surrounding air)

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.

List 2 adaptations that helped Darwin's finches survive.?
Vaselesa [24]

Answer:

Two adaptations of Darwin's Finches that helped them to survive are:

  • Beak structure.
  • Behavioral adaptations to use tools for foraging.

Explanation:

There are fourteen species of Darwin's finches that originated from a single  species of ground dwelling seed eating finch.

These Finches occupied different niche in the Galapagos island  and were widely studied by Darwin.

These finches are one of the best Examples of Adaptive radiation.

Studies state that during severe drought in Galapagos island most vegetation dried out and a few softer seeds were left.

These few seeds were quickly fed upon by the birds and only dry , hard seeds were left.

Only birds who had large and hard beaks could feed on these hard dry seeds.

To Ensure survival the Finches developed adaptations which resulted in hard and large beaks so that they can feed on those dried hard seed.

Some groups started feeding on insects and got their beaks adapted to capture and kill insects.

Second line of adaptation included changes in behaviour and cognitive intelligence where birds started using tools for foraging.

Compare the normal allele for hemoglobin with the sickle cell allele. How does this difference affect the person’s red blood cel
Readme [11.4K]

Answer:

Sickle cell anemia is an inherited condition in which there aren't enough healthy red blood cells to carry oxygen through an individual's body. The red blood cells of a healthy individual are flexible and round, and they move through blood vessels with no problem, transporting oxygen successfully. However, a person with sickle cell anemia has rigid, sticky red blood shaped like sickles or crescent moons. These cells often get stuck in small blood vessels, which can slow or block blood flow and oxygen delivery to different parts of the body.

The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene, while the regular red blood cell trait is found on the dominant allele. This means that a person must have two copies of the recessive allele (one from their mother and the other from their father) to be born with this condition. People who have one dominant and one recessive allele or both dominant alleles will have healthy red blood cells.
