According to the graph, what condition is best for enzyme activity?
O A. A temperature above 30°C
B. A temperature of 0°C
C. A temperature of 25°C
D. A temperature below 20°C
According to the graph, the condition that is best for enzyme activity is a temperature of 25 °C. The correct option is C.
What is enzyme activity?The enzyme is a protein that works in many functions or reactions and increases its speed.
The graph is at its highest between 20 and 30, so its activity will be highest at this phase.
Thus, the correct option is C. A temperature of 25 °C.

A hydroelectric dam has heated a nearby body of water.
Answer:
Not Healthy
Explanation:
Because the Fact that you said "aquatic ecosystem" changes the statement. Even though that this dam is hydroelectric, It doesn't benefit Aquatic life very much. Garbage does not come from electricity. No matter how it is made. You may get toxic gases, But not garbage. The warm water can kill the fish who may need a stable condition if no mutations occur. It can attract new praetors or fungi also.

(a) The oscilation in the pressure inside arteries and arterioles is called by the cardiac rythm. During ventricular systole the pressure rises and during ventricular diastole it decreases
(b)Because when referring to capliaries there is a smaller diameter in the cross section but the surface is bigger. This means that the pressure decreases and the blood has a steady flow instead of periodic bursts.

How many atoms of carbon, hydrogen, and oxygen are there in the reactants of photosynthesis?
Answer:
The reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms. IN HYDROGEN ATOMS It takes six atoms of carbon (C) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6). These atoms come from carbon dioxide (CO2) and water (H2O). IN OXGYEN It takes six atoms of carbon (C), six atoms of oxygen (O) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6).
In photosynthesis, the reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

In the sample of water, there are 100 atoms of oxygen and 200 atoms of hydrogen. How will the mass of oxygen compare to the mass of hydrogen?
Answer:
The ratio of the mass of an oxygen atom to the mass of a hydrogen atom is therefore approximately 16:1. If we have 2 atoms of each element, the ratio of their masses is approximately 32:2, which reduces to 16:1—the same ratio.
The mass of oxygen compared to the mass of hydrogen is approximately 16:1.
What is a chemical reaction?
There are several types of chemical reactions depending on the reaction mechanisms: combination, single-displacement, double-displacement, combustion, decomposition, combustion and redox reactions.
Thus, 16:1 is the answer.

Describe three other features of a bacterial cell.
Answer:
hope it helped
Explanation:
Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
The features of a bacterial cell are the following:
Bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.
They are essential in the decomposition processes of organic matter, necessary for the recycling of elements such as carbon or nitrogen.
They reproduce quickly and by asexual procedures, which consist of the replication of the progenitor cell in two exactly equal to it (binary fission).They are made up of a single cell without a cell nucleus, but with a nucleoid (an irregular region where the circular DNA of prokaryotes is found).They have a peptidoglycan cell wall that covers the cell outside the plasma membrane.Scattered throughout the bacterial cytoplasm are ribosomes (in which protein synthesis takes place) and there are also often plasmids (small non-chromosomal DNA molecules).Some bacterial cell also have capsules, a rigid protective structure that is outside the cell wall and flagella to move (if they are mobile).Therefore, we can conclude that bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.

Where does the oxygen released during photosynthesis come from
Answer:
Oxygen liberated during photosynthesis comes from the splitting or hydrolysis of water in the green plants. Cornelius van Niel experimentally proved for the first time that the oxygen liberated during photosynthesis comes from water and not from carbon dioxide.
Answer:
Oxygen liberated during photosynthesis comes from the splitting or hydrolysis of water in the green plants.
Oxygen is just a by product of this splitting, and will be removed from the plant.
it was proven by Cornelius Van Niel that oxygen liberated during photosynthesis comes from water not carbon dioxide

A person can become sunburned as
B. Sunlight is an electromagnetic wave carrying energy that is absorbed by the skin.
Sunlight as an Electromagnetic wave:Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon.
Sunlight is an electromagnetic wave that gains energy as it travels through the air to reach the person.

In snapdragon the gene that affects flower color has two alleles: red (R) and white (W). In heterozygous individuals, the phenotype is pink. If two pink flowers were crossed what would be the probability of a pink offspring?
A. 25%
B. 50%
C. 75%
D. 100%
Answer:
The correct answer is - 50%
Explanation:
In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:
R W
R RR RW
W RW WW
here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%
