The consequences of the introduction of c. Taxifolia to the coast of California is the disappearance of other algae species where C. taxifolia colonizes.
What are the impacts of C. taxifolia?This alga causes a marked decrease in biodiversity in the environments colonized by it. It was observed, in 1991, that it covered the beds of algae of Cymodocea nodosa and especially of Posidonia. Initially, the Posidonia seaweed bank seems to react positively to contact with the seaweed, increasing its production. Later, after being completely invaded, it shows signs of "stress" (leaf fall...) leading to a setback and then the total disappearance of the algae bank as well as the algae that grew together with the posidonias.
Whit this information, we can conclude that the consequences of the introduction of c. Taxifolia to the coast of California is the disappearance of other algae species where C. taxifolia colonizes.

Which of these is not an advantage of the arthropod exoskeleton?.
Answer:
One major disadvantage is the need to molt. Arthropods are highly vulnerable during this time, since the new exoskeleton starts out very soft and needs some time to harden. Until it hardens completely, the animal has almost no protection.

Which type of genetic drift occurs when many members of a population die, resulting in a great loss of genetic diversity?.
Answer:
Genetic drift is a process in which allele frequencies within a population change by chance alone as a result of sampling error from generation to generation. Genetic drift is a random process that can lead to large changes in populations over a short period of time.

Which of the following are sustainable land-use strategies for minimizing the impacts of urbanization?
I. Reducing native plant landscaping in a city's center
II. Building high-rise business centers in a city's center
III. Providing affordable housing options in a city's center
A. II and Ill only
B. Il only
C. I and II only
Answer:
A
Explanation:
Building high-rise business centers in a city's center is a sustainable land-use strategy for minimizing the impacts of urbanization. Therefore, the correct statement is option B.
What is an effective strategy for minimizing the impacts of urbanization?The sustainable land-use strategies for minimizing the impacts of urbanization involve promoting environmental sustainability, economic viability, etc. Reducing native plant landscaping in a city's center has negative impacts on ecosystem services.
Native plants support local pollinators, which helps in reducing urban heat island effects and also improves the air quality of the area. Building high-rise business centers in a city's center is a sustainable land-use strategy as it minimizes the use of non-renewable resources and promotes social and economic benefits and conserves open spaces in the area.
Providing affordable housing options in a city's center may be included in a sustainable land-use strategy as it promotes social equity and economic viability. However, it can have negative impacts on the environment if there is increased energy consumption or replaces ecological habitats so it depends on the situation.
Therefore, building high-rise business centers in a city's center is a sustainable land-use strategy for minimizing the impacts of urbanization.

If a pea plant’s alleles for height are tt, what is true of its parents? (Select all that apply.)
Where T is tall and t is short.
- Both parents contributed a dominant allele.
- Both parents were short.
- Both parents contributed a recessive allele.
- Both parents were tall.
Answer:
Both parents contributed a recessive allele.
Both parents were short.
this is because a recessive allele will only express itself in the absence of dominant allele
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
The Correct choice is C
If plant's allele is tt, then it means that the plant got both short (recessive) allele from both parents.
The variation of gene expression that is not related to the variation of the DNA, is transmissible, and is reversible is described as
Epigenetics is the variation of gene expression that is not related to the variation of the DNA, is transmissible, and is reversible
What is epigenetics?Epigenetics is the variation of gene expression which is not related to changes in the sequence of nucleotides in a DNA molecule but is as result of the interaction of the environment and the diet.
Epigenetics changes are reversible and transmissible but do not alter the DNA sequence, but they can affect how the DNA sequence is read.
Therefore, the variation of gene expression that is not related to the variation of the DNA, is transmissible, and is reversible is described as epigenetics.

Answer:
Choice E.
The plasma membrane is a selectively permeable barrier which allows only certain substances to enter and exit the cell.
The selectively permeable barrier of the cell that allows certain molecules to enter and exit the cell is F, which is the cell membrane or plasma membrane.
How cell membrane is composed?The cell membrane is composed of a lipid bilayer that separates the interior of the cell from the external environment, and contains various proteins that control the movement of molecules in and out of the cell.
The cell membrane is selectively permeable, meaning it allows some molecules to pass through while preventing others from crossing.
This is essential for maintaining the internal environment of the cell and regulating the exchange of nutrients, waste products, and other substances with the outside world.

suggest which factor carbon dioxide oxygen or water might limit the rate of photosynthesis
Answer:
Explanation:
Oxygen is not required for photosynthesis so we should just cross it out of the list. Secondly, the factors upon which photosynthesis depend are sunlight, carbon dioxide and temperature. So this also puts an end to water. As for carbon dioxide, if its amount is increased, the stomata of leaves will close and will not allow more of it to enter and thus process of photosynthesis will eventually decrease. And if we decrease the amount of carbon dioxide, plant will not be able to make its food properly.
