How and where is NADPH produced?
Answers
Answer:
NADPH is formed on the stromal side of the thylakoid membrane, so it is released into the stroma. In a process called non-cyclic photophosphorylation (the "standard" form of the light-dependent reactions), electrons are removed from the water and passed through PSII and PSI before ending up in NADPH.

are corks prokaryotic or eukaryotic cells?
Answers
Answer:
Cork cambium (pl. cambia or cambiums) is a tissue found in many vascular plants as part of the periderm. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems.
Comparison of Eukaryotes vs. Prokaryotes. Play media. 3D animation of aprokaryotic cell that shows all the elements that compose it. A prokaryote is a single-celled organism that lacks a membrane-bound nucleus (karyon), mitochondria, or any other membrane-bound organelle.
A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes belong to the taxon Eukarya or Eukaryota
Explanation:
Corks are a type of plant part that is eukaryotic cell having well developed nucleus.
What are corks?Cork cells are dead cells found in the bark of stems. They appear hexagonal or pentagonal under a microscope. In 1665, Robert Hook used a microscope for the first time to examine cork cells.
Plant cells that mature into mature cork cells form the protective water-resistant tissue in the outer covering of stems or trunks.
Cork cells are genetically programmed not to divide and, as a result, are considered dead cells.
Eukaryotes are organisms with nuclei and other membrane-bound organelles. Eukaryotic organisms include all animals, plants, fungi, and protists, as well as the majority of algae.
Thus, it can be concluded that the corks are eukaryotic cells.

The type of light can easily make the difference in photosynthesis.
What is photosynthesis?Photosynthesis is defined as the process through which plants employ sunshine, water, and carbon dioxide to produce oxygen and sugar energy.
It can also be defined as the conversion of light energy into chemical energy by green plants and certain other creatures.
Photosynthesis usually occurs in chloroplast of the plant cell.
Plants contains pigments which is present in the leaves of the plants that helps plant to produce food through photosynthesis.
There are basically four pigments are present in leaves of plant.

Answer: Inability to convert the light energy into chemical energy.
Explanation:
The above question relates to the issue regarding photosynthesis. Plants contain chlorophyll and this helps them in the conversion of the light energy that they get from the sunlight into a chemical energy.
In the case that no yellow-leaved seedlings were found alive in either dish, the reason for this will mainly be because the plant was not able to convert the light energy into chemical energy.

The second map gives you information about those regions. Using both maps, what can you tell about the regions in Washington that get the most or the least amount of rain?
Answers
Answer:
Explanation:
In the Precipitation Map of Washington, the dark orange section indicates low rainfall in the region. Using the Shaded Relief Map of Washington, you can tell that this area is flat, possibly a plain. These areas normally don't get a lot of moisture. The Washington Precipitation Map has regions that are dark purple and dark orange. This means that they both get a lot of rain every year. If you look at these areas on the Washington Shaded Relief Map, you can see that these areas with a lot of rainfall are mountainous.

How would being near the equator shape the amount of sunlight per day in those countries? Explain your answer.
Answers
Answer:
Explanation:
The amount of daylight that is received is directly proportional to how close the sun is to each hemisphere. This happens due to Earth's inclined axis which changes as the Earth rotates and causes more daylight in the Northern or Southern hemispheres which is when summer starts in each. That being said the Equator is the only location that has an even amount of sunshine all year round. This is why it is always hot and Equator cultures only recognize dry and wet seasons but still consider it summer all year round.

From about 4 billion years ago to about 2.5 billion years ago, oxygen gas became more common in Earth's atmosphere. Oxygen was a toxic compound to most life forms from that time period. Today, oxygen is required by all but some of the most primitive life forms. Which statement best explains how early life forms that were harmed by oxygen evolved into today's life forms that require it?
Answers
Answer:
C
Explanation:
Over time, many species gradually adapted to a more oxygen-rich environment, allowing them to survive in shallow water and on land.
From about 4 billion years ago to about 2.5 billion years ago, oxygen gas became more common in Earth's atmosphere, but the early life forms were harmed by the gas, and later those who survived passed on their genes to the next generation through evolution.
What is the significance of oxygen in evolution?Evolution is a process that explains life's ability to adapt and change over time in response to environmental conditions and the process of evolution is one of the central mechanisms driving life's diversity, but the presence of oxygen harmed early life. As life forms evolve, oxygen becomes one of their most important gases.
Hence, from about 4 billion years ago to about 2.5 billion years ago, oxygen gas became more common in Earth's atmosphere, but the early life forms were harmed by the gas, and later those who survived passed on their genes to the next generation through evolution.
