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 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.

Hope this helps you, may i have brainliest please.
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.
Some of the information that can be learnt from the fossils found in rock strata are:

4a. By 40-60 years after farm fields had been abandoned, the amount of herbaceous plants
decreased. Give one reason why the amount of herbaceous plants decreased as the amount of trees
increased.
Answer:
See the answer below
Explanation:
The amount of herbaceous plants in an abandoned farm field will keep decreasing with time and the amount of trees would be increasing instead due to successional forces.
Succession refers to the gradual change in the species structure of a community with time. Early successional species usually colonize new habitats and with time, they are replaced with late successional species until a relatively stable community, climax community, is established.
Herbaceous species on abandoned farmland represent early successional species and as time goes on, they will be replaced by mid to late successional species in the form of shrubs and trees until a relatively stable community is formed. Hence, herbs would be decreasing while trees would be increasing.
What benefit does an organism gain by only using this method of reproduction?
Explanation:
In a stable or predictable environment, asexual reproduction is an effective means of reproduction because all the offspring will be adapted to that environment. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. On the other hand, the rapid rates of asexual reproduction may allow for a speedy response to environmental changes if individuals have mutations. An additional advantage of asexual reproduction is that colonization of new habitats may be easier when an individual does not need to find a mate to reproduce.

How do algae blooms destroy aquatic life?
by giving off toxins that kill life
A harmful algal bloom (HAB) contains organisms (usually algae, hence the name) that can severely lower oxygen levels in natural waters, killing marine life.
What, besides temperature can make ocean water significantly denser
salinity
High salinity makes water denser. This is because there is more salt packed into the water. High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense.
Which area best describes a continental slope?
Continental slopes are regions of steeply sloping seafloor that lie between continental shelves and the deep ocean basins (Figure 2). Regional gradients are typically 2–5°, but locally slopes may be much steeper.
Algae blooms destroy aquatic life because of the decomposition of algae depletes oxygen needed by organisms.
How do algae blooms destroy aquatic life?When algae and bacteria in an algal bloom die, the decomposition process consumes the surrounding oxygen which leads no presence of oxygen in the water body and the aquatic organisms die because of suffocation.
So we can conclude that Algae blooms destroy aquatic life because of the decomposition of algae depletes oxygen needed by organisms.

A. It would grow until there was no more space.  B. It would decrease steadily over time.  C. It would keep growing with no limit.  D. It would grow until it had to compete for food.
The Malthus predict about the human population as it would grow until it had to compete for food. Therefore, option (D) is correct.
What are the characteristics of human population?The total number of people alive today is referred to as the world population. In the middle of November 2022, the United Nations estimated that it had reached more than eight billion.
There are 4 primary qualities of the populace structure: age, orientation, nationality, and thickness. The population structure is influenced by three main factors: Migration, mortality, and the birth rate.
Understanding how populace attributes, for example, size, spatial dissemination, age structure, or the birth and demise rates change over the long haul can assist researchers or legislatures with simply deciding.

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

Which statement below explains why water is insoluble in the middle of the semipermeable membrane.
The water molecule cannot penetrate the semipermeable membrane so it does not go through the
membrane.
The water molecule is nonpolar and the middle of the membrane is also nonpolar trapping the water
molecule.
The water molecule is polar and the middle of the membrane is nonpolar
The membrane is made from polar phospholipids allowing water to move freely in and out of the cell
Answer:
The membrane is made from polar phospholipids allowing water to move freely in and out of the cell
Explanation:
The cell membrane is the organelle of the cell that allows for substances to be transported into and out of the cell. It is able to do this due to its semi-permeability. The membrane contains a phospholipid component, which contains a polar region that allows for polar substances such as WATER to enter and leave the cell.
The polarity of the phospholipid component of the cell membrane explains why water is insoluble in the middle of the semipermeable membrane.

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).
