Answer:

The correct option is d). The process is called interstitial growth.

Explanation:

The cartilage is composed of chondrocytes, which are located in small spaces called lacunae. Its function is to synthesize the extracellular matrix of cartilage. Its growth occurs through two processes: appositional growth and interstitial growth. When chondrocytes in lacunae divide and form new matrix, it leads to an expansion of the cartilage tissue from within, the process is known as interstitial growth, this happens because the young chondrocytes divide mitotically, forming a group called isogenous, while forming the matrix, each one separates, creating its own lacunae. As a result of the increase of chondrocytes and the secretion of the new intercellular matrix, it causes the cartilage to grow (expand) from within.

Give one example of how the testing of Platismatia glauca could benefit future ecological research of this forest.
storchak [24]

Answer:

Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.

hope this helps:)

Skin color in a certain species of fish is inherited by a single gene with four different alleles. How many different types of g
k0ka [10]

Answer:

4

Explanation:

According to Mendel's law of purity of gametes, each gamete contains single allele for a gene. The alleles of a gene segregate during gamete formation and each gamete has one allele for a gene irrespective of the total number of alleles for a gene.  

If the gene for skin color in a fish species has four alleles, an individuals fish would have only two alleles which in turn would segregate during gamete formation.

Since there are four different alleles of the gene (let's assume a,b,c, and d), total possible gametes produced by this organism will be = 4. A gamete can have one of the total 4 alleles making total 4 types of the gametes each with a or b or c or d allele.

Which characteristic of the genetic code lowers the likelihood of mutation?
Rudik [331]
Degeneracy

Degeneracy simply means that most of the amino acids produced during protein synthesis from DNA is coded by more than one codon. A codon is a sequence of 3 <span>nucleotides that codes for a specific amino acid.

Because more than 1 codon can produce the same amino acid, the chances of having the synthesis of proteins affected by mutations (i.e. point mutations) is decreased. For example, if the codon with the nucleotide series GAA, which codes for the amino acid glutamate, becomes the codon GAG, the codon will still produce glutamate because the code is degenerate. </span>

Streptomycin is an effective antibiotic because _____________.
Slav-nsk [51]

Answer: Option C.

Both

Explanation:

Streptomycin is an antibiotics produced from bacteria and fungi and it is used to treat bacteria infections (prokaryotic ) such as tuberculosis, mycobacterium infection e.t.c.

It's inhibit protein function in prokaryotes because it's affects the function and performance of 70 s RIBOSOMES which is an organelles for protein production.

Streptomycin does not affect eukaryotes because it does not bind to the RIBOSOMES of eukaryotic cells which in turn does not affect protein production.
