As the territory of Africanized bees continues to expand, what is the most likely outcome?
Answers
Answer:
Competition among nectar- and pollen-feeding invertebrate pollinators and resource partitioning are affected by introduced Africanized Honey Bees. When Africanized Honey Bees compete with other species of honey bees for flowers, the Africanized bees may displace the other bees from the food sources.
In which of the following organisms did photosynthesis most likely first
evolve?
A. Algae
B. Prokaryotes
C. Plants
D. C4 plants
Answers
Compared to prokaryotic organisms such as bacteria, plants and animals have a relatively recent evolutionary origin. DNA evidence suggests that the first eukaryotes evolved from prokaryotes, between 2500 and 1000 million years ago.
The following organisms did photosynthesis most likely first evolve - B. Prokaryotes
Sufficient evidence indicates that eukaryotic photosynthesis originated from endosymbiosis of cyanobacterial-like organisms
ultimately these prokaryotes became chloroplasts in eukaryotic cells.So the evolutionary origin of photosynthesis is to be found in the bacterial domain.The geological record indicates that this transforming event took place early in Earth's history, at least 2450–2320 million years agoThus, The following organisms did photosynthesis most likely first evolve - B. Prokaryotes

Two ecosystems are compared in terms of population size and species diversity. One ecosystem has a large number of individuals but low species diversity, while the other ecosystem has fewer individuals but greater species diversity due to high mutation rates. Which of the following statements best describes how these two ecosystems would respond to an environmental stress such as drought?
The ecosystem with greater diversity is less dependent upon resources and would suffer less from the drought.
The ecosystem with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
The ecosystem with more individuals is less likely to suffer because it is more productive and, therefore, more stable.
The ecosystem with more individuals is more likely to have members that are drought-resistant and will survive and reproduce.
Answers
Answer: I had the same problem in one of my exams. I think the answer is "the ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
Explanation:
I chose this because it seems like the most logical explanation.
"The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.
What is biodiversity?Biodiversity is considered as the variety of living things found in the various habitats, such as terrestrial, marine, and desert ones, as well as the ecological groups to which they belong.
The variety of the creatures present in an ecosystem, as well as their relative abundances, is referred to as biodiversity. It also depicts the various stages of organism organization.
In ecosystem there are thirteen different grass species present and in ecosystem Y 1 species of grass present, that is, ecosystem X has a greater amount of biodiversity. So, during the drought, the bison in ecosystem X are better able to survive.
Therefore, "The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.

The following is a growth curve of bacteria. What type of growth curve is pictured? A) linear growth B) logistic growth C) exponential growth
Answers
Answer:
C) exponential growth
In the given figure, exponential growth curve is pictured.
What is exponential growth?It is the pattern of data, which demonstrates greater enhancements with passing time, giving rise to a curve of an exponential function. During the growth cycle of bacteria, the cells of bacteria goes through different phases, that is:
Lag phaseExponential phaseStationary phaseDeath phaseIn the case of bacteria, the cells enter the log or the exponential phase after the lag phase. This is the time when the cells get differentiate by the process of binary fission and double in numbers after each generation time.
In this pattern of growth, the metabolic activity is high as RNA, DNA, the components of the cell wall, and other substances essential for growth are generated for differentiation.
Thus, the pattern of growth demonstrated in the given figure is exponential growth.

(8.9B) A student made a chart to classify plates by the types of boundaries. What crustal
feature is most likely found between the South American and African plates? *
A Folded mountain
B Ocean trench
C Mid-ocean ridge
D Fault
Answers
Answer:
folded mountain
hope it will help you
The crustal feature is most likely found between the South American and African plates is folded mountain. The correct option is A.
What is folded mountain?When two or more of the tectonic plates of Earth are forced together, fold mountains are formed.
Rocks and debris are bent and folded into rocky outcrops, hills, mountains, and entire mountain ranges at these interacting, compressing limits. Orogeny, a process, is what produces fold mountains.
While having a narrower width than their length, fold mountains are very long.
Concave and convex slopes are typically present on opposite sides of fold mountains. Most fold mountains are located on the edges of continents that face the ocean.
A student created a chart to categorize plates according to the different boundary types. The folded mountain is most likely the crustal feature that lies between the South American and African plates.
Thus, the correct option is A.

Various factors influences the fluidity of the phospholipid bilayer of the cell membrane. If we were to chart the composition of cell
membranes in organisms as we move north from the equator to higher latitudes around the Arctic circle, we would expect to find
phospholipids with
A)
fewer hydrophilic heads.
B)
fewer interspersed cholesterol molecules.
both saturated and unsaturated fatty acid tails.
D
an increase in the length of the fatty acid tails.
Answers
Answer:
D
an increase in the length of the fatty acid tails.
Explanation:
As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated
and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and
decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and
more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity
