The zebra mussel, a mollusk native to Eurasia, was first discovered in the Great Lakes of North America in 1988. Zebra mussels a
Anvisha [2.4K]

Answer:

Please see below

Explanation:

A. Zebra mussels are located in the areas of the United States that they were introduced to but it continues to spread across the US as time progresses.

B. Since the Zebra mussels can attach itself to solid surfaces, boats are no exceptions. They are able to go a few days out of water which gives them enough time to remain attached until a boater takes the vessel to another lake or isolated body of water.

C. Since these are filter feeders they are growing without a natural predator since they are an invasive specie. They feed on the algae in the water and use up almost all of this food supply and makes resources for other native specie (fish) that depend on this food source to die out.

D. Burmese pythons in the Florida everglades are an invasive specie. The prey on endangered species, have no real predator and have voracious feeding habits that affect the numbers in the animal population.  

E. Non- native mongoose was introduced on Jamaica to control the snake population. The problem with introducing a non native specie would be that this new organism is also without a natural predator. After the target specie has been eliminated it may try to feed on other animals in the ecosystem as well.    

F. Invasive species need to adapt to weather conditions and should be able to hunt/acquire its food in order to survive in its new environment.

In a population of Mendel's garden peas, the frequency of the dominant A (yellow flower) allele is 80%. Let p represent the freq
k0ka [10]

Answer:

C) 64% AA, 32% Aa, 4% aa

Explanation:

The frequency of dominant allele A is = 80% = 0.8

Since the population is in Hardy-Weinberg equilibrium, p+ q =  1

Here, p= frequency of dominant allele

q = frequency of recessive allele

Given, p= 0.8

So, q = 1-p = 1-0.8= 0.2

Frequency of genotype AA = p2 = 0.8 x 0.8 = 0.64 = 64%

Frequency of genotype aa = q2 = 0.2 x 0.2 = 0.04 = 4%

Frequency of genotype Aa = 2pq = 2 x 0.8 x 0.2 = 0.32 = 32%

There are two forms of endoplasmic reticulum (ER) found in a cell. They are the rough and the smooth ER. What does the rough ER
Trava [24]

Answer:

RER is involved in protein synthesis, folding, transport and modification.

Explanation:

The Endoplasmic Reticulum is an organnelle found in eukaryotic cells. They are of two types; Rough Endoplasmic Reticulum and Smooth Endoplasmic Reticulum, so named based on the appearance of their surface. The Rough Endoplasmic Reticulum (RER) obtains it rough appearance from the membrane bound ribosomes attached to it.

Due to the ribosomes that attach to them during protein synthesis, their function is very much associated with protein synthesis. They are primarily involved in protein production, which would either remain in their lumen for further modification/processing called Glycosylation (adding sugar to proteins to form glycoproteins) or be transported through secretory vesicles to the Golgi apparatus. They also fold this proteins in their inner membrane structure called cisternae.
