Why would it be hard to find the ideal CO2 level if the light intensity were very low?

I'm assuming this question refers to the rate of photosynthesis.
Plants need both light and CO2 to photosynthesize (PHOTOsynthesis means using light to use CO2 to make O2 and other nutrients). If the light intensity were very low, the plant wouldn't have enough energy to photosynthesize much.
You could have all the CO2 in the world, but if there's not enough light, the plant wouldn't be able to photosynthesize.
In short, it'd be difficult to find the ideal CO2 level if the light intensity were very low because the plant needs a certain light level to even photosynthesize. You could only find the ideal CO2 level if you had enough of all other nutrients, and CO2 level was the only variable you were changing.

7. In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white

kondor19780726 [428]

Answer:

See the answer below

Explanation:

Genotype is the genetic composition of organisms and a gene is made up of two alleles.

a) Since the allele for black is B, the genotype for black chickens would be BB.

b) Since the allele for white is W, the genotype for white chickens would be WW.

c) Since erminette color is heterozygous, the genotype would be BW.

d) Two erminette were crossed:

BW x BW

BB BW BW WW

i. Probability of having black chick (BB) = 1/4

ii. Probability of having a white chick (WW) = 1/4

iii. Probability of having erminette chicken (BW) = 1/2

Trophic Levels describe the transfer and different stages of the organisms transferring energy. I just called it Trophic level energy flow in school.

Two cell divisions mitosis or meiosis

Troyanec [42]

Cell division is the process by which a parent cell divides into two or more daughter cells.[1]Cell division usually occurs as part of a larger cell cycle. In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis),[2] and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes(meiosis). Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions. Homologous chromosomes are separated in the first division, and sister chromatids are separated in the second division. Both of these cell division cycles are used in the process of sexual reproduction at some point in their life cycle. Both are believed to be present in the last eukaryotic common ancestor.

Prokaryotes (bacteria) undergo a vegetative cell division known as binary fission, where their genetic material is segregated equally into two daughter cells. All cell divisions, regardless of organism, are preceded by a single round of DNA replication.

For simple unicellular microorganisms such as the amoeba, one cell division is equivalent to reproduction – an entire new organism is created. On a larger scale, mitotic cell division can create progeny from multicellular organisms, such as plants that grow from cuttings. Mitotic cell division enables sexually reproducing organisms to develop from the one-celled zygote, which itself was produced by meiotic cell division from gametes. After growth, cell division by mitosis allows for continual construction and repair of the organism.[3] The human body experiences about 10 quadrillion cell divisions in a lifetime.[4]

The primary concern of cell division is the maintenance of the original cell's genome. Before division can occur, the genomic information that is stored in chromosomes must be replicated, and the duplicated genome must be separated cleanly between cells.[5] A great deal of cellular infrastructure is involved in keeping genomic information consistent between generations.

Chromosomes often exchange segments of DNA during meiosis. How might this increase the survival of a species?

il63 [147K]

Answer:

Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase

What can easily pass through the cell membrane?

Grace [21]

Answer:

i dont rlly get what ur asking but basically gasses diffues across the cell membrane from high conc to low concentration.

i dont know what passive transport is but active transport goes against the concentration gradient so im guessing passive is the opposite and goes with the conc gradient
