Answer:
Properties of the solution which changed
1. The temperature of the solution
2. The concentration of the solution
Explanation:
The properties of the solution that changed are:
1. The temperature of the solution: Once the ice cubes were added, (we will assume that the ice cubes were at 0 degrees Celcius) The system had to attain thermal equilibrium. Hence, the higher temperature of the solution melted the ice, while the ice, cooled the entire mixture.
2. The concentration of the solution reduced. We need to remember that ice is water. As the ice was added, we were indirectly adding more water to teh solution, thus diluting its concentration

All of the following are characteristics of proteins EXCEPT:
A They contain genetic information
B They can catalyze chemical reactions.
c They can transport materials.
D They can repair tissues.
Answer: A.
Explanation: Proteins are made by decoding genetic information carried by DNA, but contain no genetic information themselves. Although the sequence of amino-acids in a protein matches the code in DNA, there is no process for using protein as a template for DNA.
Proteins may be structural, like collagen in tendons or keratin in hair and fingernails, or enzymes active in metabolism, or in transport, such as haemoglobin that transports oxygen, or in transporting ions into and out of cells against a concentration gradient.

The levels of organization of the human body, from the simplest to the most complex is in the following order: Cells, Tissue, Organ, Organ System, Organism. (True or False)
Answer:
True.
Explanation:
It is true that biological levels of organization of living things arranged from the simplest to most complex are:
organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.What is biological level of organization?Levels of organization are natural systems that are frequently described by part-whole connections, with higher ones being made up of lower levels. The atomic, molecular, cellular, tissue, organ, organismal, group, population, community, ecosystem, landscape, and biosphere levels of organization are common in the literature.What is cell?The smallest unit in biology that can exist on its own and makes up all living creatures and bodily tissues. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.Hence, the above statement is true.

Considering information given in the passage and data found in the graph, select the response below that supports the argument that biotechnology has had a positive impact on both society and the United States' economy.
A.
Shull's hybrid corn seeds created a new type of science in the United States—biotechnology. After the success of his seeds, other individuals entered the field and created their own hybrids. This caused the industry to grow and gave farmers a bigger selection of seeds from which to choose. Today, farmers can purchase everything they need for a successful corn crop from their seed distributors. The hybrid seed industry in the United States makes billions of dollars each year.
B.
From 1866 to 2011, farmers produced many bushels of corn each year. They could have produced more corn if weather conditions had been favorable. The drought during the Dust Bowl was hard on farmers growing corn. Hybrid corn seeds had no effect on corn production. The impact on society and the economy were small compared with the impact of the Dust Bowl droughts.
C.
Shull developed hybrid corn seed about 100 years ago. Some farmers bought the seed when it was first produced, but others did not. Farmers would have grown corn either way. Hybrid corn seed did not have an effect on corn production overall. It helped the economy by making more money for Shull and other scientists that produced hybrid corn seeds.
D.
Shull's creation of hybrid corn seed allowed farmers to produce more corn consistently throughout the years. Overall, the number of bushels harvested each year trends higher, as shown in the graph, between 1918 and 2011. Increased corn production meant more income for the farmers, which allowed them to take better care of their families and farms. Hybrid seed performed, even during the Dust Bowl, when non-hybrid farmers struggled to produce corn.

Instinct or learned behavior?
A lizard becoming ill after eating a poisonous insect?
The response of a lizard becoming ill after eating a poisonous insect is most likely an instinctual behaviour rather than a learned behavior.
What is instinctual behaviour?Instinctual behavior, also known as innate behavior, is a type of behavior that is genetically programmed in an organism and does not require prior learning or experience. These behaviors are often complex and are typically exhibited in response to specific environmental stimuli or triggers. Instincts are common in animals and are often associated with survival and reproduction.
Examples of instinctual behavior in animals include migration, hibernation, nest building, territoriality, and courtship displays. In many cases, instinctual behavior is triggered by external environmental cues such as changes in light, temperature, or food availability.
Humans also exhibit instinctual behavior, although to a lesser extent than many other animals. For example, newborn infants exhibit innate reflexes such as rooting, sucking, and grasping. Some researchers also believe that certain aspects of human behavior, such as language acquisition and social bonding, may have an innate or instinctual component.

Ocean ecosystems are sensitive to the chemical composition of the water. Any excess compounds can upset the balance and cause damage to organisms. In three to five sentences, describe how reducing consumption of fossil fuels can help the ocean ecosystem. (
Answer: The sustainable management, conservation and restoration of coastal and marine ecosystems are vital to support the continued provision of CARBON sequestration and other ecosystem services on which people depend.
Protection and restoration of coastal ecosystems is also needed. Policies to prevent the conversion of these ecosystems to other land uses, for example regulating coastal development, can ensure their protection.
Globally ambitious efforts are also needed to reduce the use of fossil fuels, increase the use of renewable energy systems and enhance energy efficiency. This will reduce the impacts of CO2 and other GHGs on the ocean.

How humans changed the balance of the park ecosystem
Answer:
Humans change ecosystems in many ways, such as habitat destruction, pollution, introduction of invasive species, and overexploitation of species.
The most common way that humans damage ecosystems is by destroying habitat. For example, we remove trees, change the flow of water, and change grasslands into farms. These practices can lead to local extinctions of species and cause other species to migrate to new areas.

If a cell normally has 32 chromosomes, what would be the results of going through mitosis?
Answer:
For mitosis, the DNA content of the daughter cells and the mother cell will always be identical. Since the number of cells have doubled, so has the DNA. The 16 chromosomes in the mother cell will be duplicated, then the duplicates split and evenly divided into the daughter cells. The 16 chromosomes in each daughter cell will be non-duplicated at first.
