Explanation:
Homeostasis is maintained by which of the following organ systems in humans?
A. Multiple organ systems working together
B. The muscular system
C. The endocrine system
D. The nervous system
A. Multiple organ systems working together
Explanation:
All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.

A motorcycle accelerates 3 m/s2 due to a force of 330 N. What is the mass of the motorcycle? Mass of motorcycle = _____ kg
Answer:
110 kg
Explanation:
Given
Acceleration (a) = 3m/s²
Force (F) = 330N
Required
Determine the mass of the motorcycle
This question is an illustration of Newton's second law and will be solved using:
Force = Mass * Acceleration
F = m * a
This above implies that force applied on the motorcycle is a product of its mass and its acceleration
Substitute values for F, and a
330N = Mass * 3m/s²
Make Mass the subject
Mass = 330N/3m/s²
Mass = 110kg
Hence, the calculated mass of the motorcycle is 110kg
Answer:
110

What would happen if the sedimentary rock was exposed to energy from the sun and then millions of years later to energy from Earth’s interior?
Answer:
They would become igneous rocks
Explanation:
If originally, sedimentary rocks are exposed to energy from the sun, no changes will occur to them.
One will hardly spot any difference in their mineralogical composition as such.
The temperature of the sun does not any significant alteration on earth materials. The heat from the interior has a very significant effect on rocks, especially sedimentary rocks. Heat from the interior can reach a staggering 6000°C which is more than enough to cause a metamorphic change in a body rock. In fact, at this temperature, igneous rock will be produced from the sedimentary rock.Igneous rock will be produced from the sedimentary rock if the sedimentary rock was exposed to energy from Earth’s interior for millions of years.
The temperature of the sun does not make any significant changes on sedimentary rocks.
The heat from the interior has a very significant effect on sedimentary rocks.Heat from the interior can reach upto 6000°C which is able to cause a metamorphic change in a rock.Therefore, igneous rock will be produced from the sedimentary rock if the sedimentary rock was exposed to energy from Earth’s interior for millions of years.

how do photosynthesis and cellular respiration form a cycle?
Answer:
The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Which best describes a codon?
a cell structure that gives the master instructions for an organism
a segment of DNA that is the basis of heredity in organisms
the sequence of three bases that codes for a specific amino acid
the basic unit of structure and function of all living things
Answer: the sequence of three bases that codes for a specific amino acid
Explanation: I took the test and i got this answer correct so i hoped this helped!!
Codons are generally a sequence of three bases in the DNA and RNA that codes for specific amino acids. So option C is correct.
What is a genetic code?A genetic code is a set of information that helps to convert the genetic information stored inside the genetic material into a defined sequence of amino acids called a protein.
Though the DNA has nucleotide sequences that contain information for producing the proteins, the DNA cannot directly synthesize the proteins. It is first converted to mRNA in order to be translated into a specific protein.
There are in total 64 codons, out of which 61 code for specific amino acids while the remaining three codons are known as stop codons and are used in terminating the process of translation of proteins.

En un experimento un floricultor cruzó plantas de flores púrpuras con plantas de flores blancas, los resultados obtenidos durante la primera generación fueron de un 100% de flores púrpuras, y en la segunda generación un 25% de flores serán de color blanco y el resto de color púrpura. Los genotipos de los parentales (P)
Answer:
Los genotipos de los parentales son:
- pp (homicigota dominate con flores púrpura)
- bb (homocigota recesivo con flores blancas)
Explanation:
Alelos:
p: púrpura y b: blanco
Genotipos parentales:
- pp: homocigota dominante (flores púrpura)
- bb: homocigota recesivo (flores blanca)
Cruzamiento parental: pp X bb
F1: 100% pb
Cruzamiento F1: pb X pb
F2: 25% pp (flores púrpuras), 50% pb (flores púrpuras) y 25% bb (flores blancas)
En este caso, el alelo que determina el color púrpura es dominante sobre el alelo que determina el color blanco. Es por esta razón que en la F1 todas las plantas heterocigotas exhiben un fenotipo con flores púrpura. En la F2 la proporción fenotípica será 1:2:1 (1 homocigota dominante, 2 heterocigotas y 1 homocigota recesivo), mientras que la proporción genotípica será 3:1 (3 plantas con flores púrpuras y 1 planta con flores blanca).

How might retaining too much heat be a disadvantage to an organism?
Excessively heat can damage the plasma membrane and disrupt subcellular structures such as membrane proteins and enzymes.
What are subcellular structures?The following are the primary subcellular structures found in animal cells: The nucleus is where genetic material is stored.
Cell membranes regulate what enters and exits the cell. Mitochondria: aerobic respiration site. Ribosomes are the sites where proteins are synthesized.
Protein denaturation occurs at high temperatures and affects protein folding, bonding, and other types of behavior.
Furthermore, membrane proteins play an important role in cell function regulation. If these are disrupted, the system will be unable to maintain homeostasis, or a stable internal environment.
Heat can damage the plasma membrane and disrupt subcellular structures like membrane proteins and enzymes.
Thus, this way, retaining too much heat can be a disadvantage to an organism.

Which of the following must occur before DNA replication can take place?
Answer:
Before replication can occur, the length of the DNA double helix about to be copied must be unwound. In addition, the two strands must be separated, much like the two sides of a zipper, by breaking the weak hydrogen bonds that link the paired bases.

How does the chromosome number of daughter cells compare with the amount of chromosomes in parent cells?
Answer:
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

What cell membrane structure allows water-soluble materials to be passively transported to the cytoplasm?
A. Endocytosis vesicles
B. Carrier proteins
C. Hydrophilic phospholipid tails
D. Golgi complex vesicles
Answer:
B. Carrier proteins
Explanation:
Water-soluble materials, such as glucose, amino acids, and ions, need help to cross the membrane because they are repelled by the hydrophobic tails of the phospholipid bilayer. The tails are not hydrophilic.
Endocytosis vesicles are an example of active transport, they require energy to allow large molecules to be taken into the cell through a system of vesicles.
Golgi complex vesicles deliver proteins and other macromolecules outside of the cell from the inside.
Carrier proteins can participate in both active and passive transport across cell membranes. For example, carrier proteins with channels can help molecules cross the membrane passively.
Why is the protein coding of most human genomes identical?
