Answer:
Anabolism
Explanation:
As a noun:
the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy; constructive metabolism.
Anabolism is the set of metabolic pathways that construct molecules from smaller units. These reactions require energy, known also as an endergonic process. Anabolism is the building-up aspect of metabolism, whereas catabolism is the breaking-down aspect. Anabolism is usually synonymous with biosynthesis.

Describe the process of asexual reproduction in the following I)Amoeba 2) Rhizopus 3)yeast 4)spirogyra
Answer:
1)Amoeba reproduces by the common asexual reproduction method called binary fission. After replicating its genetic material through mitotic division, the cell divides into two equal sized daughter cells. ... In this process, the nucleus of the Amoeba first divides to form two daughter nuclei by the process of Karyokinesis.
2)Rhizopus is the species of a fungus. They reproduce asexually by the formation of the spores. ... The sporangium is a swollen structure at the tip of the filaments bearing the spores. The spores are tough and resistant structures which are dispersed by the breaking of the sporangium.
3)Budding in Yeast .Most yeasts reproduce asexually by an asymmetric division process called budding. First it produces a small protuberance on the parent cell that grows to a full size and forms a bud. The nucleus of the parent cell splits into a daughter nucleus and migrates into the daughter cell.
4)Spirogyra species can reproduce both sexually and asexually. Asexual, or vegetative, reproduction occurs by simple fragmentation of the filaments. Sexual reproduction occurs by a process known as conjugation, in which cells of two filaments lying side by side are joined by outgrowths called conjugation tubes.

Which statement about an isotonic solution is correct? * 7 points The solution has the same solute concentration as the cell. The solution has a higher solute concentration than the cell. A cell in the solution will lose water. A cell in the solution will gain water.
Answer:
The solution has the same solute concentration as the cell.
Explanation:
Tonicity of a solution refers to the ability for a solution to direct the flow of water into or out of a cell via osmotic process. Based on this, a solution can either be hypertonic, hypotonic and isotonic.
- A hypertonic solution is a solution in which the solute concentration is high in relation with that of an intracellular solution. Hence, water moves out of the cell.
- A hypotonic solution is a solution which solute concentration is low in relation to that of an intracellular solution. Hence, water moves into the cell.
- An ISOTONIC solution is a solution that has the same solute concentration as that of an intracellular environment i.e. equal solute concentration. There is a net water movement

1. Yeast uses photosynthesis to provide its own energy. True or False 2. Yeast has chlorophyll. True or False 3. Given the statements below, choose the one that is true about one-celled living things. 1. Under normal conditions, yeast produces spores. 2. The adult stage for one-celled organisms is usually extremely long. 3. Algae can only be unicellular. 4. Because of its size, algae does not make much oxygen for the earth.
Answer:
1. False
2. False
3. The adult stage for one-celled organisms is usually extremely long.
Explanation:
1. Yeast is a fungus that uses heterotrophic means of obtaining food. A yeast cell does not have the ability to perform photosynthesis (provide energy source) because it cannot make use of light energy from the sun. Hence, the answer is FALSE.
2. The cells of a yeast lacks chlorophyll pigment needed for the capturing of light energy. Hence, this statement is FALSE.
3. Yeast is a unicellular organism that reproduces via spores and budding. Budding is the asexual form of reproduction while they produce spores when stressed. However, the adult stage for one-celled organisms is usually extremely long.

Explanation:
. A researcher confirmed her hypothesis by obtaining data through a scientific study. She published her work and results, while proudly stating she had developed a new theory. How would other scientists most likely react to this claim? A. They would support her claim of a new theory because she supported it with data. B. They would support her theory because she published her research for others to use. C. They would reject her new claim because her hypothesis probably disagrees with others' studies. D. They would reject her claim of a new theory because she was the only person to complete the scientific study.
Answer:
A. They would support her claim of a new theory because she supported it with data.
Explanation:
A scientific study is done to confirm the hypothesis which is based on scientific data. Scientific data is defined as factual information collected by doing experiments or methods for studying a specific purpose.
As shown in the question, a girl publishes her work and results based on scientific study and scientific data, so she would get support from other scientists on her claim of a new theory because she supported it with data. A new theory based on scientific data is more accurate and true.
Hence, the correct answer is "A."

Explain why the muscular system cannot act alone to perform a skill such as rock climbing. Describe what other systems must be a part of this rock climber's game plan.
Answer:
It has to act together with the nervous system.
Explanation:
The muscular system executes the actions that are coordinated and given by the nervous system, without this neuromuscular set manufactured by the motor plate, the muscle would even be hypotonic and atrophied in addition to not being able to execute the action of climbing.
Answer:
Since the muscular system performs acts that are orchestrated and given by the nervous system, the muscular system must work in conjunction with the nervous system. Without this neuromuscular collection manufactured by the motor plate, the muscle will be hypotonic and atrophied, as well as unable to perform the operation of climbing.

How does the cell membrane help maintain homeostasis for the cell? * 1 point By providing a circular structure for all cells By making proteins to provide the cell with energy By regulating the transport of materials in an out of the cell By storing food as future energy for the cell
Answer:
By regulating the transport of materials in an out of the cell
Explanation:
Cell members regulate homeostasis by regulating transport of material in the cell.
Cell membrane serves as boundary that separate the internal environment from the external environment in the cell, It is selectively permeable allowing some materials pass through while it regulate the passage of other material.
Molecules are transported across the cell membrane using two mechanism the active transport and passive transport.
Active transport requires the use of energy while passive transport occurs when molecules moves randomly.
The cell membrane helps maintain homeostasis for the cell by regulating the transport of materials in and out of the cell.
The cell membrane is a selectively permeable barrier that surrounds the cell and separates its internal environment from the external environment. It plays a crucial role in maintaining homeostasis, which is the stable internal balance of the cell.
One of the primary functions of the cell membrane is to regulate the movement of substances in and out of the cell. It controls the entry of essential molecules, such as nutrients and oxygen, into the cell, while also allowing waste products and other substances to be expelled. This regulation is important for maintaining the appropriate concentrations of substances within the cell, which is essential for its proper functioning.
The cell membrane achieves this regulation through various mechanisms such as passive diffusion, facilitated diffusion, and active transport. It uses specialized proteins embedded in the membrane, such as channels, carriers, and pumps, to selectively allow or block the passage of specific substances. This control over the transport of materials helps the cell maintain the optimal internal conditions necessary for its survival and function.
By regulating the transport of materials, the cell membrane helps maintain homeostasis by preventing the entry of harmful substances and ensuring the availability of essential nutrients. It also helps in maintaining the appropriate balance of ions and molecules within the cell, which is critical for various cellular processes.
In summary, the cell membrane plays a crucial role in maintaining homeostasis by regulating the transport of materials in and out of the cell, allowing for the proper functioning and survival of the cell in its specific environment.

Butter is a fat that is a solid at room temperature. What type of fatty acids does butter contain? If you studied its molecular structure what would you se tht is different from fats that are liquid at room temperature
Answer:
saturated fatty acids
Explanation:
Butter is a fat that is solid at room temperature because it is a saturated fatty acid and contains 70 percent of It. Butter comes from a cow, which is an animal source.
Fats that are liquid at room temperature are unsaturated fatty acids. The molecular structure of saturated fatty acid and unsaturated fatty acid are different as saturated fatty acids lack double bonds while unsaturated fatty acids consist of at least one double bond. saturated fatty acids are linear and unbranched while unsaturated fatty acids are branched.
Hence, butter contains saturated fatty acids.
