What are marine algal blooms, red tides, and dead zones? How might biological magnification play be part in human illness?

Answers

Answer 1

Answer:

Cyanobacteria, a type of photosynthetic bacteria also known as blue-green algae, are often the cause of algal blooms in freshwater and occasionally in marine water. ... Cyanobacteria HABs produce multiple toxins, including liver, nerve, and skin toxins, which can affect human and animal health.

Many red tides produce toxic chemicals that can affect both marine organisms and humans. The Florida red tide organism, K. brevis, produces brevetoxins that can affect the central nervous system of fish and other vertebrates, causing these animals to die.

Genetic engineers use plasmids. A plasmid is
A. a map of a gene.
B. a cell that is not yet specialized.
C. a small, circular piece of DNA.
D. an enzyme that can cut DNA into pieces.

Answers

Answer:

C. A small, circular piece of DNA

Explanation:

A plasmid, usually circular but sometimes linear, is a small double-stranded DNA unit, which is chromosome independent and is capable of self-replication. Each plasmid carries only a few genes. Carrying only a few genes, the plasmid’s size ranges from 1 to more than 1000 kbp. Genes required for organism survival and those that are generally beneficial to the host organism, such as antibiotic resistance, are often found in plasmids [1].

Mostly plasmids can be found in bacteria, but they are also present in multicellular organisms and archaea. Plasmids usually contain at least one gene and are not considered independent life forms even though they possess separate genes from their hosts

The answer is C.
A plasmid is a small, often circular DNA molecule found in bacteria and other cells. Plasmids are separate from the bacterial chromosome and replicate independently of it. They generally carry only a small number of genes, notably some associated with antibiotic resistance.

Which of the following is true about the founder effect?
A) The founder effect results in an increase in genetic variation.
B) The smaller population remains the same as the original, larger population.
C) The founder effect inhibits the expression of rare traits.
D) The founder effect is a type of genetic drift.
E) none of the above

Answers

Answer:

Among the following statements shown, the most accurate concerning the founder effect is that (b) It results when a small population breakers away from a larger one. Founder Effect is defined as the reduced genetic diversity which is most likely caused when a population is descended from a small number of colonizing ancestors.

The true statement about founder effect is "the smaller population remains the same as the original, larger population".

A force of 2.20 N is exerted on a 7,20 g rifle bullet. What is the bullet's acceleration? (Enter your answer in m/s^ 2 )

Answers

Answer:

The answer is 306 m/s^2

Explanation:

F = m*a

We can rearrange this formula to get a = F / m.

The SI unit for mass is kilograms (kg).

The SI unit for acceleration is m/s^2.

There are 1000 grams in a kilogram.

7.20 g = 0.00720 kg

Force (2.20 N) / 0.00720 kg = 305.56 m/s^2

Accounting for Sig Figs, the answer is 306 m/s^2.
