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.

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.

Explanation:

Brainliest please?

Answer:

[tex]\boxed {\boxed {\sf H. \ Enzymes \ act \ as \ catalysts \ to \ drive \ chemical \ reactions \ forward}}[/tex]

Explanation:

Enzymes are catalysts.

They lower the activation energy required to carry out a reaction, which speeds up the reaction. They attach to a molecule known as a substrate at the active site in a specific way.

Enzymes are incredibly important for life. Many reactions wouldn't occur at a rate that can support life, but enzymes allows this to happen. They assist in digesting food, replication genetic material, and more.

So, we know that enzymes are catalysts that make reactions efficient. Therefore, choice H is the best answer.

What benefit does an organism gain by only using this method of reproduction?

Answers

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.

with an initial vity both the balls reach the ground at the same time, culate the value of u​

Answers

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

A strawberry farmer finds that, after a hard freeze, some of his strawberries are still alive. Which best explains why these stran

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.

Answers

The answer is B. They have different genetic variations that caused them to be more resistant to cold temperatures.
Explanation:
Sorry if I’m wrong.

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.

a. diffusion
b. active transport
C. endocytosis
d.
a sodium-potassium pump

Answers

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.

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.

Answers

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.
