if an earthworm is 18mm long and is photographed and the picture is magnified 2.5x how long will it be in the picture?
Answer:
The earthworm will be 45 mm long in the picture
Explanation:
From the problem, we can take the original size of the earthworm to be 18mm.
Magnification can be obtained using the formula:
magnification = observed size/ original size.
Recall, we are given that the magnification is 2.5.
Hence, can evaluate the size in the picture to be
2.5 X 18mm = 45mm

Does a Hematopathologist work with unicellular or multicellular organisms? Select the BEST answer.
Select one:
a. Multicellular
b. Both equally
c. None
d. Unicellular
Answer:
b
Explanation:
A hematopathologist is a health care professional who works with the unicellular or multicellular organisms, both equally. Thus, the correct option will be B.
Who is a Hematopathologist?Hematopathologists can be referred to as the specially trained healthcare professionals who are responsible for the diagnosis of the diseases related to the different types of blood cells.
Hematopathologists use the specialized tests such as flow cytometry studies and the immunohistochemistry. The hematopathologist uses the results of these tests for the analysis and diagnosis of the infections and diseases of the blood, lymph nodes and the bone marrow.
A hematopathologist works with both the unicellular and multicellular organism equally.
Therefore, the correct option will be option B.

the earliest form of spongy bone in a developing long bone is termed
Answer:
Osteoid
Explanation:
The earliest form of spongy bone in a developing long bone is termed as Osteoid.
Osteoid is defined as the the unmineralized, matrix material that is made up of a fibrous protein, collagen, and mucopolysaccharide and forms prior to the maturation of bone tissue.
Osteoblasts, the process of formation of bones takes place when inorganic salts starts depositing over osteoid to form the hardened material.
Hence, the correct answer is "Osteoid".

An individual has the genotype Aa Bb CC Dd ee FF. How many different types of gametes could it produce in terms of unique allelic combinations of these genes?
Answer:
64
Explanation:
The individual in this question with genotype: Aa Bb CC Dd ee FF has six (6) different traits encoded by six (6) genes. The diploid number of the organism in this question is 12, however, the number of possible allelic combinations in each gamete can be calculated by using 2^n where n = haploid number of chromosome or number of allele that can be in one gamete.
Using this simple formula, 6 possible alleles can be in the gamete of this organism with the above genotype, hence, the individual can produce 2^6 = 64 different types of gametes in terms of unique allelic combinations of these 6 genes.

- Which occurrence is the result of the cell cycle in unicellular organisms?
A. cell repair
B. cell growth
C. cell replacement
D. cell reproduction
Answer:
D
Explanation:
Cell reproduction is the result of the cell cycle in unicellular organisms. The correct option is D.
What is cell reproduction?Cells split to produce multiple cells with similar, if not identical, contents. This process is known as cellular reproduction.
Nuclear division during mitosis produces two somatic cells that are genetically identical to the parent cell and have the same genetic complement.
Asexual reproduction in prokaryotes takes the form of cell division in unicellular organisms.
When an organism splits in half, it creates two totally distinct daughter cells, a process known as binary fission. The daughter cells are identical to the parent cells genetically.
Most of the time, Paramecium reproduces asexually via budding, however in poor circumstances, they produce sexually.
Unicellular organisms have a variety of asexual reproduction strategies, including multiple fission, fragmentation, and budding.
Thus, the correct option is D.
