6 0

The symbol on a regulatory marker that indicates hazards such as rocks or stumps is an Orange Diamond. Regulatory markers are types of non-lateral markers such as white and orange markings that are used as navigation aids that give directions, warn of dangers and marks controlled locations. Orange diamond shapes warns of dangers such as rocks, stumps or construction.

Certain varieties of chrysanthemums contain 18, 36, 54, 72, and 90 chromosomes; all are multiples of a basic set of nine chromos
AlekseyPX

The question is incomplete as it does not have the options which are:

aneuploids

allopolyploids

amphipolyploids

autopolyploids

Answer:

Autopolyploids

Explanation:

Autopolyploid refers to the ploidy condition in organisms in which the ploidy level of organism increases that is multiple set of a single chromosome is formed in tissues.

The autopolyploids condition is observed more frequently in the plants than the animals when the tissue cells divide.  In the given question, the chromosome number increases or double that is from 18 to 36 to 54, 72 and 90. This shows that the ploidy level is increasing.

Thus, Autopolyploids is correct.

Digest excess or Worn-out cell parts, Food particles, and invading viruses or bacteria.
nataly862011 [7]

the answer could not be D because a Golgi Apparatus  is a tiny structure, or organelle, in a cell that "packages" nutrients for use inside the cell. The answer could not be c. because a nucleus  is a tiny structure, or organelle, in a cell that "packages" nutrients for use inside the cell. The answer could not be  Endoplasmic Reticulum because that is where proteins are transported from one part to the other. So the only answer left is Mitochondria, because the Mitochondriamain function is to produce ATP, the energy currency of the cell.

The frequency of autosomal alleles K and k in a large population of snails is 0.6 and 0.4. What is the approximate genotypic fre
Flura [38]

Answer:

Option (b).

Explanation:

The frequency of alleles K and k in population are 0.6 and 0.4. The inbreeding coefficient is 0.3.

The heterozygote frequency can be calculated by the formula:

F = \frac{2Kk-H}{2Kk}

Here, K = 0.6, k= 0.4, F = 0.3 and H = approximate genotypic frequency of heterozygote Kk.

Put the values in the above formula

0.3 = \frac{2\times2\times0.6\times0.4-H}{2\times0.6\times0.4}

H = 0.36 ≈ 0.34.

Thus, the approximate genotypic frequency of the heterozygote Kk is 0.34.

Hence, the correct answer is option (b).
