If different masses of water are heated to the same temperature, the sample that will absorb more energy will be the mass of water with the greatest amount of water mass, because the larger the material, the greater the amount of heat needed.

<h3>What is the specific heat of water?</h3>

Water has a specific heat of 1 cal/g. ºC This means that the energy of 1 cal is required for a variation of 1 °C in 1 g of water.

With this information, we can conclude that Water's specific heat power is 4.2 joules per gram per Celsius degree or 1 calory per gram per Celsius degree.

Assume that an organism exists in which crossing over does not occur, but that all other processes associated with meiosis occur

expeople1 [14]

Answer:

The options are missing, they are:

a.The daughter cells of meiosis I would be diploid, but the daughter cells of meiosis II would be haploid.

b.The two sister chromatids of each replicated chromosome would no longer be identical.

c.The four daughter cells produced in meiosis II would all be different.

d.The two daughter cells produced in meiosis I would be identical.

e.There would be less genetic variation among gametes.

f.Independent assortment of chromosomes would not occur.

The correct answer is E, there would be less genetic variation among gametes.

Explanation:

Crossing-over or also called recombination is a phenomenon peculiar to meiosis alone. Meiosis is that kind of division that is employed by sexual-reproducing organisms to produce gamete/sex cells. Crossing-over is a process that may or may not occur, if it does, it occurs in prophase of meiosis I, and it involves exchanging equal chromosomal segments between two non-sister chromatids or homologous chromosomes. Crossing-over is the means by which sexually reproducing organisms use to bring about genetic variation among their species.

It is worthy to note that the non-occurrence of crossing-over does not affect the number of chromosomes as a normal meiotic division will always yield haploid gametes right from meiosis I.

Since crossing-over did not occur, the homologous chromosomes (similar but non-identical chromosomes) will separate into each cell during meiosis I, meaning that each cell will have chromosomes that are either maternal or paternal. This will reduce the chance of genetic variation occuring among species.

Put the steps of zygomycete sexual reproduction in the right order. Start with the production of multinucleate gametangia at the

Vesnalui [34]

Answer:

Choice 4 of 5. Hyphae produces multinucleate gametangia

Choice 1 of 5. Gametangia fuse

Choice 2 of 5. Karyogamy occurs and zygosporangium develops

Choice 5 of 5. A dark, thick-walled zygospore develops

Choice 3 of 5. Meiosis occurs to produce haploid spores

Explanation:

The steps of zygomycota sexual reproduction are;

Germination step; Hyphae produces multinucleate gametangia

Plasmogamy step; Gametangia fuse when compatible mating types of mycelia are brought close to each other by the formation gametangia between

The fusion of the nuclei results in the formation of zygosporangium that has multiple haploid nuclei and a thick wall

Karyogamy step; A zygote having multiple diploid nuclei is formed by the fusion of nuclei

Germination and Meiosis step; The sporangia grows and haploid spores are produced

Therefore, we have;

Choice 4 of 5. Hyphae produces multinucleate gametangia

Choice 1 of 5. Gametangia fuse

Choice 2 of 5. Karyogamy occurs and zygosporangium develops

Choice 5 of 5. A dark, thick-walled zygospore develops

Choice 3 of 5. Meiosis occurs to produce haploid spores
