Answer:

1. Gametophyte

2. Sporophyte

Explanation:

The life cycle of the Liverwort and mosses which are placed in the Bryophytes is divided into the sporophytic and the gametophytic phase.

Gametophyte

The gametophyte is the dominant phase of the life cycle which appears like the ribbon, green in color and posses the gamete producing structure- the antheridium and the archegonium.  

Sporophyte

The gametes fuse to form the embryo and from that is produced the sporophyte structure, an umbrella-like structure called a sporangium. This sporangium produces the spores which later will form the gametophyte.

During the process of photosynthesis,
TEA [102]

Answer:

d. less than 100% of the energy captured from sunlight is transformed into potential energy in the form of a hydrogen ion gradient and then into potential energy in the form of covalent bonds

Explanation:

Photosynthesis is process utilized by plants, several bacteria and protists to convert the light energy to chemical energy. So they utilize the photosynthesis as the powerhouse for the energy production. Heterotrophs like human that cannot synthesize their own food, use this converted form of energy by autotrophs.

During the light reaction of photosynthesis the photons from light are absorbed by photosystem I and II. These photons excites the electrons which flow through the electron transport chain from higher potential to lower potential. These electrons release the energy while moving from higher potential to lower potential which is utilized by H+ pump to pump the H+ to lumen of plastids from stroma and of course not the 100% energy is utilized some of the energy dissipates. . So this process causes the accumulation of high potential H+ ions across the membrane. These H+ ions are utilized for the production of ATP by ATP synthase complex when they flow back to lower potential across the membrane through ATP synthase complex.

The ATP and NADPH produced from light reaction are utilized to combine carbon molecules during dark reaction. The covalent bond is used to combine the carbon molecules and we know that combining carbon molecules stores energy in the form of covalent bond.

You can measure and describe climate by walking out the door and describing current atmospheric conditions. true or False
Xelga [282]

Answer:

The answer is "False."

Explanation:

The sentence above is stating that you can<u> "measure"</u> and describe climate by "walking out the door and describing current atmospheric conditions." This is "false" because climate cannot be measured by qualitative descriptions or subjectively. Measuring it entails quantity which is objective in nature. An example of this is by using "thermometers" or "rain gauges."

Although you can describe the atmospheric condition or the climate just by walking out the door,<em> you can never measure it.</em>

Thus, this explains the answer.
