Answer:

Yeast cell structure

Each yeast cell has a distinct cell wall enclosing granular cytoplasm, within which can be seen a large vacoule and a nucleus (Fig. 214). The vacuole varies much in size according to the state of activity of the cell.

Yeast contains almost the same organelles of a mature eukaryotic cell. Nucleus, Golgi apparatus, mitochondria, endoplasmic reticulum, vacuole, and cytoskeleton are the most important one. Yeast cell particle size is typically of 5×10μm.

Explanation:

Yet, we don't always think of yeast as something remarkable. Instead, it's often perceived as plain or dull—a single-celled organism that, like a plant, lacks the ability to move on its own accord.

Answer:

Substitution, missense mutation

Explanation:

Mutation is a change in the DNA sequence that can subsequently alter the genetic message.

Substitution mutations occurs when a base is replaced with another different base.

A good example is the one given in the question where the third A in the sequence ACAAAC is replaced by a T.

If this kind of mutation occurs in a protein-coding gene, it will be classified as a frameshift mutation.

Missense mutation is caused when there is a change in a single nucleotide that results to the coding of a different Amino acid

A natural disaster caused a piece of land to break away from the mainland.

Viktor [21]

Answer:

The correct options are :

A) The biodiversity will decrease because there are fewer species on the newly formed island.

D) The species on the island will likely have lower genetic diversity than the species on the mainland.

Explanation:

When a larger population is broken down and a smaller population is formed, the genetic diversity in the smaller population will be lower as it has fewer species. As a result, options for genetic variations will be lesser. Hence, the landmass which drifted away will have lower biodiversity than the mainland. There will be more number of species on the mainland hence the genetic diversity will be more there.

Exponential decay, a paleontologist finds a bone that might be a dinosaur bone. in the laboratory she finds that the carbon-14 f

Nitella [24]

The half-life of Carbon-14 is 5760 years.
For carbon-14 to have decayed down by a factor of 12, we know between 3 and 4 half-lives must have elapsed. Since 4 half-lives is only 23,000 years, the sample is considerably younger than a dinosaur bone. (Unless we assume it's been contaminated with modern carbon, in which case, any age calculation based on carbon-14 is worthless.) 
The decay equation is y = ae^(-0.0856t) with t in days. 
To find the half-life, we solve for t such that y/a = 0.5. 

0.5 = e^(-0.0856t) 
Take natural logs of both sides: 
-ln(2) = -0.0856t 

-0.6931 = -0.0856t 
Divide both sides by -0.0856... 
8.096 = t 

The half-life is 8.096 days.
