What are organelles and which type of cell has organelles? *
Answer:
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
eukaryotes have organelles
Answer:
membrane bound and nonmembrane bound . Non-membrane bound organelles are ribosome and cytoskeleton whereas membrane bound organelles are nucleus and endoplasmic.
Explanation: Prokaryotic cells have organelles
Uncle Smiley, who is heterozygous for a yellow face, married a woman with a green face. Both of them have always wanted a large family! If they were to have 12 children, how many of the 12 children would have yellow faces? How many of the 12 children would have green faces? Create a Punnett square to to help you find your answers. Hint: Yellow face is dominant to green face
Answer:
Since Yellow is dominant over green then almost all of the children will have yellow faces. The punnet square below will show what the offspring will have but my guess is
50% will have yellow faces
50% will have both yellow and green
1% will have a green face
But since Yellow is dominant over green the 50% of both colors will mostly show a yellow dominant.
I apologize if my drawing looks messy.

A normal cell has a high concentration of potassium on the inside and a low concentration of potassium on the outside. Also, a normal cell has a low concentration of sodium on the inside and a high concentration on the outside. Yet, the net movement of potassium is into the cell and the net movement of sodium is out of the cell. What type of transport is involved?
Osmosis
Facilitated diffusion
Active transport
Diffusion
Answer:
Is there a higher concentration of potassium inside or outside the cell?
The sodium and chloride ion concentrations are lower inside the cell than outside, and the potassium concentration is greater inside the cell. These concentration differences for sodium and potassium are due to the action of a membrane active transport system which pumps sodium out of the cell and potassium into it.

What force is present at a divergent boundary?
A. Shearing
B. Torsion
C. Tension
D. Compression
Tension force is present at a divergent boundary. Therefore, option (C) is correct.
What do you mean by tension force?Tension is defined as the force transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.
Tension formula is articulated as. T=mg+ma. Where, T= tension (N or kg-m/s2) g = acceleration due to gravity (9.8 m/s2)
All physical objects that are in contact can exert forces on each other. We give these contact forces different names based on the types of objects in contact. If one of the objects exerting the force happens to be a rope, string, chain, or cable we call the force tension.

What happens to the energy that is passed to the primary consumer
Answer:Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. ... At each level, called a trophic level, about 90% of the energy is lost.

What are the components of a multicellular organism?
Answer:
Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells.
Answer:
Because the first multicellular organisms were simple, soft organisms lacking bone, shell or other hard body parts.

C. A eukaryotic animal cell
D. A eukaryotic plant cell
Answer:
it would be answer c
Explanation:
A eukaryotic plant cell is the correct classification of this cell. So, the correct option is D.
What is a Eukaryotic cell?A eukaryotic cell is defined as the type of cell that has a true nucleus, and other organelles are well defined and enclosed in a membrane that has a large and complex cell that distinguishes them from prokaryotes.
This is the cell with a true and well-defined nucleus, lysosomes, cell membrane, and a cell wall is a characteristic of a plant cell because they are enclosed in a cell wall, unlike animal cells. Eukaryotic cells are found in animals and plants, while bacteria and archaea have prokaryotic cells.
Therefore, a eukaryotic plant cell is the correct classification of this cell. So, the correct option is D.

which statement best describe the relationship between the products of photosynthesis and the reactants in cellars respiration
Answer:
Photosynthesis products serve as a chemical energy suppliers for reactants and cellular respiration.
Since photosynthesis creates oxygen and oxygen needed for cellular respiration in the production of carbon dioxide and energy, carbon dioxide is used to generate plant energy and oxygen.
Explanation:
Photosynthesis products produce chemical energy by reacting to cellular respiration. Photosynthesis products interact to extract ATP from cells in cellular breathing reactants.
Photosynthesis products inhibit the reactants in the presence of light in cellular breathing.

When an organism can tolerate specific chemicals meant to kill it, it is said that the organism has developed a(n) ______________________ to the chemical.
Answer:
Immunity.
Explanation:
The organism has developed an immunity to the chemicals meant to kill it. An immunity allows the organism to not be effected anymore by it and survive.
Hope this is correct, have a great day!
When an organism can tolerate specific chemicals meant to kill it, it is said that the organism has developed an Immunity to the chemical.
What is meant by the term Immunity ?Immunity pertains to an individual body’s ability to restrict the incursion of pathogens. Pathogens are foreign disease-generating substances, which includes bacteria and viruses, and humans are susceptible to them on a daily basis.
Antigens are attached to the surface of pathogens which further arouses an immune response in the body of an individual. Immune response or immunity refers to the body’s capability to defend and to fight against antigens and protect the body.
There are various types of immunity, which consists of innate immunity, passive immunity, and acquired/active immunity.\
1) Innate immunity refers to standard protection that a person is born with already acquired since birth, consisting physical barriers (skin, body hair), defense mechanisms (saliva, gastric acid), and generic immune reactions (inflammation).
2) Passive immunity refers to an individual body’s ability to resist pathogens by “borrowing” antibodies. For illustration, antibodies could be transmitted to a baby from a mother’s breast milk, or via blood products consisting antibodies like immunoglobulin that can be diffused from one person to another.
Thus, when an organism can tolerate specific chemicals meant to kill it, it is said that the organism has developed an Immunity to the chemical.
