Answer:
Palm oil plantations have lesser habitats, communities, trophic levels, and niches that result in weak ecosystems.
Explanation:
Oil palm plantation is a crop that is high in demand for the extraction of palm oil used for various purposes like the formation of soaps, cleaning products, washing powder, and production of food products.
Oil palm plantation is mainly responsible for deforestation, pollution, and habitat fragmentation. Trees are grown at a particular distance and neighboring other species are removed so that the palm trees receive the nutrients from the soil and it will also facilitate easy harvest. Only one tree species is palm tree allowed to grow and other species are restricted as they can mask the sunlight by their canopy making it unavailable for oil palm plants.
Thus due to habitat fragmentation involving discontinuity in an organism's preferred environment of survival fewer habitats of species can be found as few species which can inhabit the oil palm plants can survive, and the ecosystem becomes weak. As the species are interdependent on each other for food needs. The low number of plant species will reduce the population of faunal species from the location. The functional roles or niches are affected by species, the whole biotic community or ecosystem gets disturbed. This will reduce the population of the species and reduce the overall biodiversity of a region.

Which shows the levels of organizational hierarchy listed from least complex to most complex?
O population, community, ecosystem
O ecosystem, population, community
O community, population, ecosystem
O community, ecosystem, population
Answer:
I think the answer to this question is O population, community, ecosystem.
Population, community, and ecosystem show the levels of organizational hierarchy from least complex to most complex. Therefore, the correct statement is option A.
What is the community consisting of?A community is made up of all the populations of different species that live in the same area and interact with one another. A population is a group of people from the same species who live there.
A biological system remembers every one of the living organic entities for a local area, as well as the actual climate in which they live and connect. In this order, the population is the most un-complex level, as it alludes to a gathering of people of similar species.
Community is more complicated because it involves interactions between multiple species populations. Because it encompasses all living and nonliving components of an area as well as their interactions, the ecosystem level is the most complex.
Therefore, population, community, and ecosystem show the levels of organizational hierarchy from least complex to most complex.

Society has changed its view of smoking since the 1960's. The major cause of this change was
All else being equal, as compared to an organism with a lower surface-area-to-volume ratio, an organism with a higher surface-area-to-volume ratio would likely have less difficulty maintaining a constant internal environment. lose more heat to the environment in cold environments. have greater thermal inertia. lose less heat to the environment in cold environments.
Answer:
lose more heat to the environment in cold environments
Explanation:
This is because as an animal have large surface area, it is exposed largely and prone to loss of heat. The larger the size of an animal, the larger the surface area and volume. It's surface area expose the tendency for the animal to sweat alot , through sweating heat is loss to the environment. In cold environment, the animal try to maintain internal homeostasis and through this heat is generated and loss to the environment.
If something is 12 grams and has a volume of 1.6 cubic centimeters, how many grams per cubic centimeter.
Answer: 7.5 grams per cubic centimeter.
Explanation:
We area given that , Mass of something is 12 grams
Volume of that thing is 1.6 cubic centimeters
To find gram per cubic centimeters, we will divide Mass by Volume ( which computes Density)
Number of gram per cubic centimeters = [tex]\dfrac{12}{1.6}[/tex]
Number of gram per cubic centimeters = 7.5
Therefore, 7.5 grams per cubic centimeter. (density of the thing)
Glycolysis results in a net gain of ____ ATP molecules.
A.
1
B.
3
C.
2
D.
4
Answer:
C: 2
Explanation:
Glycolysis yields two ATP molecules, two NADH molecules, and two pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, generates energy in the form of ATP, NADH, and pyruvate, which then feeds back into the citric acid cycle to generate additional energy.
In the process of glycolysis, glucose eventually decomposes into pyruvate and energy, yielding a total of 2 ATP. Therefore, option (C) is correct.
What is glycolysis?The metabolic mechanism known as glycolysis is responsible for the transformation of glucose into pyruvate. This process results in the liberation of free energy, which is then put to use in the production of high-energy molecules such as adenosine triphosphate and reduced nicotinamide adenine dinucleotide. Enzymes are responsible for catalyzing each of the ten processes that make up glycolysis.
The breakdown of glucose into pyruvate and energy occurs at the end of glycolysis. This process results in the production of a total of two ATP molecules.
Therefore, option (C) is correct.

Which of the following requirements for the Hardy-Weinberg equilibrium is not being met?
Answer:
A
Explanation:
All mating must be totally random
Hardy-Weinberg equilibrium is a mathematical model that describes the genetic equilibrium of a population in terms of allele frequencies. It states that allele frequencies in a population remain constant over time in the absence of any evolutionary forces.
What are the requirements of the law ?In order for this balance to be maintained, five basic requirements must be met: large population size, random mating, no mutations, no migration, and no natural selection. In this case, the starfish population does not satisfy the fifth requirement for no natural selection.
Natural selection occurs as individuals with the purple allele die off, resulting in the red allele becoming more common over time. This type of directional selection causes allele frequencies to deviate from Hardy-Weinberg equilibrium.
Therefore, no natural selection requirement is met in this starfish population. This causes allele frequencies to change over time, leading to a deviation from Hardy-Weinberg equilibrium.

A population of tree frogs lives in an area that has many types of plants and trees. The skin of most of the frogs is gray, which blends in better with the bark of trees than with the leaves of plants. Some of the frogs have skin that is greener in color, which blends in better with grasses and leaves. Snakes and birds are predators of the frog. Humans have come to the area and are beginning to cut down the trees. Describe the probability of survival for the three frogs of each genetic variation of skin colour if most of the trees are cut down. Use evidence in the paragraph to support your answer.
Answer:
with the normal natural predators their chances of survival are high but when humans step in entire forests can be wiped out which will endanger every species of frog
If most trees are cut down, grey individuals will not survive because they will be more exposed to predation. Green frogs will show a greater survival rate. Directional selection is favoring the green phenotype and its genotype.
What is directional selection?
Directional selection is one of the different types of natural selection.
It increases the proportion of individuals with an extreme phenotypic trait.
It causes a decrease in the number of individuals expressing intermediate phenotype, and the other extreme phenotype.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
In the exposed example, there is a natural environmental pressure: predation. Frogs need to camouflage to avoid being seen by birds and snakes.
Most frogs are grey. They camouflage with the bark of treesSome other frogs are green. They camouflage with the grass and leaves.The curve in a graph frequency vs phenotype shows a higher frequency of gray individuals.
When humans cut down the trees, they are applying another pressure to the population.
Since humans remove trees, grey frogs remain without a substrate in which to camouflage. They are now exposed to predation.
Birds and snakes can detect the gray frogs better and prey on them.
The grey phenotype and its genotype are affecting the animals' fitness. Grey frogs do not get to survive. So natural selection does not favor it.
Natural selection tends to benefit the green phenotype, which is now the one that increases the frogs' fitness. Green animals are not seen by predators, so they get to survive.
The curve in a graph frequency vs phenotype now shows a higher frequency of green individuals and a sharp decrease of grey frogs.
If more trees are cut down, grey individuals will not survive. However, green frogs will show a greater survival rate.
Directional selection is favoring the green phenotype and its genotype.
