<span>a. replicate DNA at the appropriate time.

Prokaryotes are one celled organism that only reproduce by binary fission. A copy of a copy, of course the DNA is copied as well. DNA is duplicated a succinct period of time when necessary since the energy needed to perform this process is necessarily abundant. </span>

The primary factors which determine each biome are: (Multiple choice)

s2008m [1.1K]

Answer:

The primary factor which determines a biome is the climate. Temperature and precipitation essentially determines what kind of growing season or soil quality the terrain may have,which therefore affects the growth of plants living there.

A wild-type tomato plant (Plant 1) is homozygous dominant for three traits: solid leaves (MM), normal height (DD), and smooth sk

Brut [27]

Answer: In this type of cross between MmDdPp and mmddpp, the phenotypic ratios in the eight possible phenotypes are as follow; a. solid, normal, smooth = 1:8

b. solid, normal, peach = 1:8

c. solid, dwarf, smooth = 1:8

d. solid, dwarf, peach = 1:8

e. mottled, normal, smooth = 1:8

f. mottled, normal, peach = 1:8

g. mottled, dwarf, smooth = 1:8

h. mottled, dwarf, peach = 1:8

Explanation: The number of gametes that can be formed from a particular genotype is given as 2^n where n is the number of heterozygous loci. In the genotype MmDdPp, n = 3. Therefore, 8 gametes can be formed.

In genotype mmddpp, n = 0. Therefore, only one type of gamete can be formed.

Crossing the two genotype (MmDdPp and mmddpp) as shown in the attached image, 8 possible offsprings can be achieved. Phenotypes of these offspring had been stated earlier. The phenotypic frequency of each of these offspring is one out of eight (⅛).

Which of the following statements represent evidence supporting the endosymbiotic theory? Check all that apply.

Tems11 [23]

Answer:

The statement that says " The mitochondrion contains a circular chromosome that has bacterial DNA sequences" is true among the all statement given above.

Explanation:

The Endosymbiotic theory that is other wise known as the symbiogensis illustrates the occurrence of the eukaryotic cell from the prokaryotic cells. Mitochondria and plastids are the most studied example in support of this theory. This theory explains that the aforementioned organelles are formed as they are taken inside in one another by the prokaryotic cell. Some of the evidences in support of this theory are mentioned below:

Phylogenetic similarity between the mitochondria and chloroplast to the proteobacteria and cynobacteria respectively.
Ability of these organelles to divide only through binary fission as the bacterial population.
The associated ribosomes are similar to the bacterial ribosomes.
Presence of porins in these organelles similar the bacterial membrane.
