Phoenix [80]3 years ago
6 0

Answer:

Dark green Marchantia gametophytes (sexual plants) are branched and ribbonlike, about 1.3 cm (0.5 inch) wide and 5 to 13 cm long. The diamond-shaped markings on their upper surfaces, signs of interior air chambers, have a central pore through which air diffuses.

Explanation:

he diploid zygotes develop into sporogonium or sporophyte. The sporophyte is differentiated into the foot, seta, and capsule containing numerous sporogenous cells, which by meiosis cell divisions forms the tetrad of haploid spores that represent the first gametophytic stage.

THE NUCLEUS, BECAUSE FIRST OF THE NUCLEUS CONTROLS MOST OF THE HEREDITARY INFORMATION OF DNA YOU KNOW WHAT IS RIGHT? (DEOXYRIBONUCLEIC ACID) WHICH IS FOUND ON THE CHROMOSOMES. ALL THE OTHER ORGANELLES THAT DOES THERE OWN FUNCTIONS ARE CONTROLLED BY THE NUCLEUS. FOR EXAMPLE:

NUCLEUS: HEY RIBOSOMES!!
RIBOSOMES: YEA BOSS?
NUCLEUS: GO TO THE ENDOPLASMIC RECTULUM AND PRODUCE PROTEINS THERE
RIBOSOMES: YOU GOT IT BOSS!

SEE.... RIBOSOMES PRODUCE PROTEINS  FOLLOWING CODED INSTRUCTIONS THAT COME FROM THE NUCLEUS.  "THE CONTROL CENTER"

g The Electron Transport Complex (ETC) consists of four proteins. How many of these proteins directly contribute to the proton g
vladimir2022 [97]

Answer:

Three proteins directly contribute to the proton gradient by moving protons across the membrane

Explanation:

The Electron transport chain is a group of proteins and molecules incrusted in the internal mitochondrial membrane and organized into four complexes, I, II, III, and IV. These complexes contain the electron transporters and the enzymes necessary to catalyze the electron transference from one complex to the other. Complex I contains the flavine mononucleotide -FMN- that receives electrons from the NADH. The coenzyme Q, located in the lipidic interior of the membrane, conducts electrons from complex I and II to complex III. The complex III contains cytochrome b, from where electrons go to cytochrome c, which is a peripheric membrane protein. Electrons travel from cytochrome c to cytochromes a and a3, located in the complex IV. Finally, they go back to the matrix, where they combine to H+ ions and oxygen, to form the water molecule. As electrons are transported through the chain, protons are bombed through three proteinic complexes from the matrix to the intermembrane space. These are complexes I, III and IV.

In the area near an old copper mine,no plant grow. Go further away more and more plants are growing. An analysis of the soil nea
maks197457 [2]

Plants do not grow near the old copper mine because of the excess copper deposited in them impairs cellular processes and inhibits plant growth.

What are micronutrients?

These are required by plants in much smaller quantities less than 1% of the dry weight but are necessary for growth and development. There are 7 essential plant nutrients like boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), and, chlorine (Cl).

Copper activates some enzymes in plants that are involved in lignin synthesis and are required in the process of photosynthesis.

Excess copper causes reduced seed germination, low shoot vigour, and lower iron availability. A deficiency of copper can lead to increased to susceptibility to diseases like ergot, which can cause significant loss in the yield.

Plants growing in the old copper mine have the excess deposition of copper in one place which affects the germination of seeds hence it is found difficult to grow in the old copper mine.

Plants can grow easily in a place that is further away from the old copper mine. Because there is a high concentration of copper dissolved in water in the soil, this helps the plant to grow by exhibiting the photosynthesis process.
