Answer and Explanation:
FALSE
Personal boats and watercraft DO contribute to ocean pollution.
Most water vehicles need fuel to be powered and go through the water. This fuel can sometimes go into the water, polluting the surrounding area.
Watercraft that don't use fuel, but instead are man-powered, can still contribute to ocean pollution. People can bring items such as soda cans, beer bottles, fishing equipment, etc., and any of these items tend to be discarded into the water, leading to pollution and degradation of the ecosystem, harming any wildlife that lives there.

How does the thickness of a material affect insulation?
Which of Nikola Tesla's inventions was the coolest?
Do all objects fall to the ground at the same speed?
Which laboratory experiment is the most fun?
The following are the questions in which a testable hypothesis be developed:
Does the width of a rubber band affect how far it will stretch?How does the thickness of a material affect insulation?Do all objects fall to the ground at the same speed?Thus, the correct options are 1, 2, and 4.
What is Hypothesis?A hypothesis may be defined as a proclamation or group of information which is mandated to be experimented with using an investigation procedure.
The width of the rubber is a variable quantity that can be measured, observed, and recorded in the conclusion. Similarly, the thickness of the material is also varied with respect to certain terms and conditions, and hence can be measured observed, and recorded in the experimental data.
Therefore, it is well described above.

Based on the reactivity of catalase in the enzyme concentration lab, do your results in testing enzyme concentration support your hypothesis?
There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.
What is an enzyme?The enzymes are the chemical molecules that alter the chemical reaction when added in a specific amount, it either increases the reaction, or decrease it.
There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.
Because the substrate concentration increased each time, there was a greater chance that the substrate would bind to the active site and carry out the reaction.
Thus, this way the enzyme concentration affects the reactivity.

The molecular bonds between atoms are considered to be _____ in a food item, before you eat it.
Group of answer choices
chemical energy

cytoplasmic energy
Answer:
Chemical energy
Which form of energy does our food contain?
Yes, food serves as a basic source of the nutrients and energy needed to maintain and grow the body. Food contains what is referred to as "chemical energy" in terms of energy. This is nothing more than the bonds between the atoms that make up the specific food item, which the body may break down to release energy that it can use to create, repair, and ensure appropriate bodily function. This chemical energy is ultimately sunshine energy, which plants have the extraordinary capacity to use and store in the chemical compounds they produce, mostly in their leaves, using sunlight, water, and atmospheric carbon dioxide. Food does indeed contain energy, but that energy ultimately originates from the sun. Since people have known this for thousands of years, many civilizations revere the sun, along with water, air, and of course fire, as the source of life. For the body to function, energy is required by the muscles, brain, heart, and liver. The food we eat provides us with this energy. Our bodies break down the food we consume by combining it in the stomach with fluids (acids and enzymes). The carbohydrate (sugars and starches) in food is broken down into another form of sugar, termed glucose, during digestion in the stomach. The glucose is absorbed by the stomach and small intestines before being released into the circulation. Upon entering the bloodstream, glucose can either be utilized right away for energy or stored for later use. But in order to utilize or store glucose for energy, our systems need insulin. When insulin is absent, glucose remains in the circulation, which raises blood sugar levels. The glucose is burnt inside of your cells to create heat and adenosine triphosphate (ATP), a chemical that stores and releases energy as the cell requires. Either oxygen is present throughout the process of converting glucose into energy, or it is not. In the mitochondria, which are microscopic structures located in the gel-like fluid that fills every cell, glucose is transformed into energy using oxygen. This conversion results in waste products including water and carbon dioxide as well as energy (ATP, heat). Without oxygen, red blood cells convert glucose into energy because they lack mitochondria. ATP, heat, and lactic acid are produced as a result. Muscle cells also use glucose as a source of energy. Muscle cells are, well, double-jointed when it comes to converting glucose into energy. They can metabolize glucose with oxygen because they contain mitochondria. However, if the muscle cell's oxygen level plummets, the cells can simply convert glucose into energy on their own without it. When you have been working out so hard that you are physically out of breath, this is most likely to occur.

help meee,A study was carried out on the emission of N2O in a sewage treatment plant (ETE) in the metropolitan region of Rio de Janeiro.
of January. During the study period, this ETE received sewage from 470,000 inhabitants. One particularity observed is that in addition to receiving domestic sewage, this station received, during a certain period of the day,the material leached from a sanitary landfill, responsible for causing an increase in the load of organic matter in the ETE in study. Continuous measurements of dissolved oxygen concentration and N2O emission were carried out at this station for 3
hours, in the period prior to the entry of the material leached from the landfill and in the period immediately after the entry of this material.
1-Why, soon after the material from the landfill, the concentration of dissolved oxygen decreased;
2-Why is there a significant increase in the emission of N2O soon after the entry of the leached material from the landfill? What bacterial processes can contribute to the increase in the emission of this observed gas
in this experiment?
The emission of N2O from the landfill site is called denitrification and it is caused by the action of denitrifying bacteria.
What is dissolved oxygen?The term dissolved oxygen refers to the amount of oxygen that is present in a water body. Now, we know that the addition of organic matter into water requires oxygen to break it own thus the dissolved oxygen content will go down in response to the added organic load.
The process that leads to the emission of N2O from the landfill site is called denitrification and it is caused by the action of denitrifying bacteria.

Geopolitics can be given as the study of the influence factors such as geography, economics, and demography on politics and especially the foreign policy of a state. Thus, the correct option is D.
Who coined the term geopolitics?Around the turn of the 20th century, the Swedish political scientist Rudolf Kjellén first used the term "geopolitics," which expanded throughout Europe in the years between World Wars I and II (1918–39) before becoming widely used during the latter. Geopolitics is frequently used as a colloquial term for international politics in modern speech.
After World War II, geopolitical theory lost favor due to its links to imperialistic Japanese and Nazi German aggression as well as because the development of nuclear weapons and ballistic missiles diminished the importance of geographical variables in the global strategic balance of power.
The definition of geopolitics stands for the analysis of the factors including geography, economics, and demography on politics and foreign policy. Thus, option D is correct.

A student, who is studying two different cells A and B in cell cycle, notices that cell A has 5 picograms of DNA while cell B has 10 picograms of DNA. Both cells are from the same organism. Which of the following is the best description of the cell cycle stage of each cell?
A. Cell A is in prophase of mitosis; Cell B is in metaphase of mitosis.
B. Cell A is in G1 phase; Cell B is in G2 phase.
C. Cell A is in G1 phase; Cell B is in between G1 and S phase.
D. Cell A is in G2 phase; Cell B is in G1 phase.
Answer:
As the cell enters meiosis 1, it's DNA replicates in S phase and then reduces to half when the cell splits into two. Hence, the amount of DNA remains 10 pg.
During meiosis 2, there is no DNA replication but only division between cells, leading to 5 pg of DNA in all four daughter cells.
So, the correct option is '10 pg and 5 pg respectively'
