Answer:
Convergent Evolution
Explanation:
Convergent evolution is the development of similar traits, across many lineages by plants and animals who originally do not have these traits but developed them because of the biome that they find themselves. Carnivorous plants are examples of living things that have undergone carnivorous evolution.
Plants lacking in Nitrogen have undergone carnivorous evolution for up to seven lineages. Sundews for instance have developed flypaper traps, a carnivorous property that helps them trap insects that they eventually digest.

were able to survive?
A. They have larger leaves to protect the fruit than the other strawberries.
B. They have different genetic variations that cause them to be more resistant to cold temperatures.
C. They are able to reproduce more quickly than the other strawberries.
D. The color of the strawberries is darker, and they maintain their temperature better than other strawberries.
The statement that best explains why these strawberries were able to survive is as follows:
They have different genetic variations that cause them to be more resistant to cold temperatures.Thus, the correct option for this question is B.
What is Genetic variation?Genetic variation may be defined as the differences or alterations that are generally found on the genomic sequences of the individual of the same species. Genetic variation increases the chances of survivability of individuals among large population.
It may also be characterized as the existence of differences in sequences of genes between individual organisms of a species.
The genomic sequences of those strawberries that have resistance against cold temperatures must survive in extremely cold conditions are the rest are eliminated from their habitat.

Answer:
The lithosphere is located below the atmosphere and above the asthenosphere.
Explanation:
The lithosphere layer is located at the outermost solid layer of the earth where the rocks and mountains are present, and it is also considered the earth's crust and the uppermost part of the mantle.
What is the significance of the lithosphere of the Earth?The lithosphere of the earth is significant because in this layer has all the earth's continents and ocean floors are contained, and it is the solid outer layer of the earth that has been providing the foundation for life on the earth's surface, including human civilization and other life forms. From this lithosphere layer, different earthquakes can be measured too.
Hence, the lithosphere layer is located at the outermost solid layer of the earth where the rocks and mountains are present, and it is also considered the earth's crust and the uppermost part of the mantle.

41. Which of the following does not expend (use) energy?
a. diffusion
b. active transport
C. endocytosis
d.
a sodium-potassium pump
Answer: diffusion
Explanation: Diffusion expends no energy. Rather the different concentrations of materials in different areas are a form of potential energy, and diffusion is the dissipation of that potential energy as materials move down their concentration gradients, from high to low.
Among the options given, the process of diffusion does not expend or utilize energy. Thus, the correct option for this question is A.
What is Diffusion?Diffusion may be characterized as a type of movement of individual molecules of a substance from an area of higher concentration to an area of lower concentration through a semipermeable barrier. This biological movement cannot utilize any metabolic energy.
According to the context of this question, active transport is a type of transport of individual substance against a concentration gradient that actively require the use of metabolic energy. Apart from this, endocytosis and sodium-potassium pump also required energy for successful function within the body of living organisms.
Therefore, the process of diffusion does not expend or utilize energy. Thus, the correct option for this question is A.

What trend in the complexity of life over time is seen through the fossil record?
Most animal and plant species we see in the fossil record are extinct, or no longer living. In fact, of all the species that ever lived, 98% are extinct. Animals and plants become extinct over time as a result of natural processes. Their habitat might change or a disease might wipe out a species.
The trend of extinction and difference in body parts in the complexity of life
over time is seen through the fossil record
Fossils refers to remains of living organisms which have been replaced in the form of rock particles due to its presence in the soil for a long period of time.
The fossils contain an understanding of the structures and characteristics
the animals had which is then compared to its present structures. This helps
to explain how the animals adapted to climate change through changes in
the structure, shape of parts of the body.
It also tells the location of animals and their different movements in response to challenges faced in the ecosystem.

What can we NOT learn from the fossils found in rock strata?
Answer:
The location of fossils in rock layers provides evidence of Earth's past landscapes. It is hard to guess the age of rock. Scientists have to act like detectives, piecing together a mystery to determine how long ago rocks formed. Fossils found in a particular rock layer help scientists determine the age of the rock.

What we cannot learn from the fossils found in rock strata is: the diversity of organisms at a certain location or during a certain time period.
Rock strata (layers) that are found in various parts of the world are usually different from one another because they all comprises distinct Earth's geological history, which are referred to as fossils.
A fossil can be defined as the mineral impression or remains of both living and non-living organisms that are prehistoric in nature.
This ultimately implies that, fossils are ancient organisms such as plants and animals that were formed into rocks.

Two students went for a walk in a small pond ecosystem where they observed several interactions. Read their observation below to find out what they saw. Small fish were found feeding on the green algae. Fish, frogs and snails were harder to find after a family of raccoons came to the pond. Fish and frogs were observed catching insects. As the amount of green algae increased, more insects and snails came to feed on it. A sample of the pond water contained bacteria.
Answer:
a food web
Explanation:
What they saw was a food web, which refers to connections of food chains showing how energy and nutrients are transferred from one organism to the other.
In this example, we observe there are seven organisms (fish, algae, snails, insects, frogs, raccoons + bacteria contained in the pond) in focus here.
The green algae are Producers (because it produces its own food, not dependant on others)
The bacteria act as Decomposers. ( because they process organic waste into meaningful natural nutrients again)
The other organisms are Consumers. (because they are dependant on others for their nutrition).
