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.

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.

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.

Monarch butterflies are toxic to birds because monarch caterpillars eat milkweed.viceroy butterflies closely resemble the monarchs but are not toxic sinse the viceroy caterpillars do not eat milkweed. This similarity in appearance developed because viceroy butterflies that closely resemble monarchs are-
A) less likely to produce offsprings
B) less likely to be eaten by birds
C) more likely to make with monarchs
D) more likely to eat milkweed
Answer:
B Trust me
Explanation:
Less likely to be eaten by birds
The similarity in appearance between monarch butterflies and viceroy butterflies developed because viceroy butterflies that closely resemble monarchs are less likely to be eaten by birds. Thus, option B is correct.
What are viceroy butterflies?Limenitis archippus is scientific name of viceroy butterflies which is a North American butterfly. Since the viceroy is distasteful to predators, it is considered a Müllerian mimic.
The viceroy found in most of the contiguous United States as well as parts of Canada as well as Mexico. The caterpillar of viceroy butterflies feeds on trees in the willow family Salicaceae which includes willows, poplars, cottonwoods. The caterpillars isolate salicylic acid in their bodies, and therefore tastes bitter, and upsets predators' stomachs.
In natural phenomenon called Müllerian mimicry two or more well-defended species, which are foul-tasting and sharing common predators, mimic each other's honest warning signals.
Therefore, Monarch butterflies and viceroy butterflies are less likely to be eaten by birds so option B is correct.

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).
A ball is dropped from height of 45 m. A second ball is thrown downwards from the same
with an initial vity both the balls reach the ground at the same time, culate the value of u
Answer:
h = 45 m
g(acceleration due to gravity) = 9.8 m/s^2 or 10 m/s^2
Final velocity ( v ) = 0 m/s
v = ?
we know theirs equation of motion, v^2 = u^2 + 2gh
0 = u^2 + 2(-10)(45) [ The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing.]
0 = u^2- 900
900 = u^2
u = √900 = 30 m/s

After transcription, what is the role of messenger RNA?
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.
