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.

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:

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.

The Malthus predict about the human population as it would grow until it had to compete for food. Therefore, option (D) is correct.

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.

Stephanie will test substances to make sure quality and safety standards are met.

Explanation:

got it right on the quiz

Answer:

C & B.

Explanation:

Answer:

Digestive enzymes speedup reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecules the body can use. Without digestive enzymes, animals would not be able to break down food molecules quickly enough to provide the energy and nutrients they need to survive.

Explanation:

Explanation:

The common dietary monosaccharides galactose, glucose and fructose are all reducing sugars. Disaccharides are formed from two monosaccharides and can be classified as either reducing or nonreducing.

Answer:

ATP, oxygen, and hydrogen

Explanation:

The photolysis is the breakdown of water in the presence of light. (H₂O->2H⁺,2e⁻,1/2O₂). From this equation ,we can safely deduct that the products that are directly formed from photolysis are 2 hydrogen protons, 2 electrons and 1/2 oxygen molecules

Answer:

Homeostasis is the way animals maintain a stable internal balance in their body. It allows animals to function in the changing external conditions surrounding their body. Homeostasis is important to Chinook salmon because they depend on the functioning of its cells to help its survival and ability to reproduce.

Answer: Incomplete dominance

Explanation: In incomplete dominance, there will be a mixture of the two alleles. In codominance, both alleles are expressed in the phenotype. In this case, an example of codominance would be the flower being half white and half red.

Answer:

Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.

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.

Answer:

Kinetic energy of moving water

Explanation:

A hydroelectric facility is a special type of power plant that uses the energy of falling or flowing water to generate electricity. They do this by directing water over a series of turbines which convert the potential and kinetic energy of water into the rotational motion of the turbine.

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

Answer:

1) Index fossils are of organisms that lived over a wide area. They lived for a fairly short period of time. An index fossil allows a scientist to determine the age of the rock it is in.

2) Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

Explanation:

Answer:

Some fossils, known as index fossils, help geologists balance rock layers. A fossil must be broadly dispersed to be a valuable index fossil and indicate a form of organism that has lived for a short time. Index fossils are valuable when the relative ages of the rock layers are told.

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.
