Answer:
C. A law describes the observation, while the theory explains the how or why.
Explanation:
So in general science, an observed phenomenon is the description of the scientific law. However the explanation of the phenomenon is called a scientific theory. Which would make this answer: c. A law describes the observation, while the theory explains the how or why.

What will happen if there were no enzymes to aid in reactions
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.

A red flower is mixed with a white flower and the offspring come out all pink what type of dominance is this?
A. Incomplete
B. Codominance
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.
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.
What is the function of enzymes in biological systems?
f Enzymes act as substrates when the
necessary proteins are unavailable.
g Enzymes bond with substrates to
create the new reaction products.
h Enzymes act as catalysts to drive
chemical reactions forward.
j Enzymes act as products to create
new chemical reactions.
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.
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.
products formed in photolysis
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

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

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.

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.
