why does the rate of photosynthesis increase when the light intensity increases.

please don't say "because there is more light available to drive the reactions of photosynthesis. "

Answers

Answer:

As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. ... A limiting factor could be the amount of chlorophyll molecules that are absorbing the light.

Answer:

If you continue to increase the intensity of light that a plant receives, what happens? The rate of photosynthesis increases with light intensity. ... The rate of photosynthesis increases and then levels off.. As the light intensity increases the rate of photosynthesis follows (point B on the graph). This means more carbon dioxide is being absorbed by the plant for photosynthesis. So this means more carbon dioxide uptake occurs. The graph shows this increase in carbon dioxide uptake.

Answer:

Mitosis, part of asexual reproduction because it produces diploids

Explanation:

Meiosis and mitosis are both kinds of cell division.

During mitosis, the DNA of a diploid cell is duplicated and passed on to two daughter cells, each with a diploid genome. This can be used as a method of asexual reproduction (reproduction without the need of a second organism).

Meiosis is a type of cell division specific to sexual reproduction. A diploid parent cell duplicates its DNA, then undergoes two rounds of replication to create four haploid cells. These haploid cells are the gametes. The gametes of two individuals (sperm and egg) fuse during sexual reproduction to create a zygote.

Mitosis, part of asexual reproduction because it produces diploids. The Option A.

Is mitosis a part of asexual reproduction?

Mitosis is a cellular process that involves the division of a cell's nucleus into two identical daughter nuclei. It is commonly associated with asexual reproduction because it allows for the production of genetically identical offspring.

During mitosis, the replicated DNA is evenly distributed to the daughter cells resulting in the preservation of the original genetic material. This process typically occurs in diploid cells, which contain two sets of chromosomes.

The correct statement about biogeochemical cycles is:

move through abiotic and biotic regions

What are biogeochemical cycles?

They are the connection and movements that exist between living elements (biotic factors) and non-living elements (abiotic factors) in order for energy to flow.

Characteristics of biogeochemical cycles

It is the exchange of chemical elements between living beings and the environment that surrounds them

They involve both the different forms of life (plant, animal, microscopic, etc.), as well as inorganic natural elements and compounds (rain, wind, etc.)

Therefore, we can conclude that biogeochemical cycles deal with a perpetual displacement of matter from one place to another and two parts or compartments can be recognized: the biotic and the abiotic.

What do you think happens to the number and the branches of nerve cells as babies mature

Answers

As a child grows, the number of neurons remains relatively stable, but each cell grows, becoming bigger and heavier. The proliferation of dendrites accounts for some of this growth. The dendrites branch out, forming “dendrite trees” that can receive signals from many other neurons when babies get mature.

What main idea about the nature of the cell did historical scientists disagree on?
PLEASE HELP IM GONNA FAIL SCIENCE

Scientists didnt belive that there are cells untill robert hooke (1665). He observed the cells in a cork slice with the help of a PRIMITIVE microscope

Leeuwenhoek (1674), with the help of an improved microscope, discovered free living cells in pound water for the first time.

It was robert brown in (1831) who discovered the nucleus in the cell.

Purkinjie in 1839 coined the term 'protoplasm' for the fluid substance of the cell.

THE CELL THEORY, that all plants and animals are composed of cells and that the cell is the basic unit of life, was presented by two biologists, schleiden (1838) and schwann(1839). The cell theory was fuether expanded by virchow (1855) by suggesting that all cells aris form PRE-EXISTING cells. With the discovery of the electron microscope in 1940,it was possible to observe and understand the complex structure of the cell and its various organelles.

Well, thats the history of the discovery of cells.
