What did Malthus predict about the human population?
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.

products formed in photolysis
Answer:

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

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

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.

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.

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.
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.
Using these words: cell division, Mitosis and DNA explain the product of mitosis and how it is achieved
Answer:
Mitosis is the process of cell division, that is, dividing one cell into two almost the same new cells, with the same number of chromosomes as the cell had when it began to divide.
Explanation:
Man contains 46 chromosomes in body (somatic) cells and 23 chromosomes in gametes. The process of division takes place in several phases: prophase, metaphase, anaphase, and telophase.
Before the cell division begins, the complete material is doubled, which will be divided into two "daughter cells" during the division.
This phase is called the interphase and it is the period between the two divisions. During this period, the cells grow and the amount of DNA doubles. Chromosomes are in the form of thin threads and are not visible.
Answer: Mitosis is a process in which a single cell divides into two identical daughter cells through cell division. During mitosis, one cell divides once to form two identical cells. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent's cell's cytoplasm. The major purpose of mitosis is for growth and to replace worn-out cells.

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.

Explain how index fossils can be used to date newly discovered fossils.
Identify another method that could be used to determine the age of the fossil.
Explain why determining the age of the new fossil find is important to scientists.
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.
