A structure within a cell that performs a specific function is a(n)
A. organelle
B. organ
C. endoplasmic reticulum
D. flagella
Answer:
A structure within a cell that performs a specific function is an organelle.
Explanation:
An organelle is a structure inside the cell that preforms functions that are necessary for the cell.
Examples of organelles are the ER, the Golgi Apparatus, and the Mitochondria.
Hope this helps.
A structure within a cell that performs a specific function is an organelle. An organelle is a subcomponent of a cell.
What are cell organelles?Cell organelles are the ultrastructure's present in the cell and they show division of labor.
These organelles perform specific function for the cell and thus constitute the framework of all living organisms.
The basic structure of cell contains a plasma membrane, nucleus and cytoplasm. However, ultra-microscopic structures are embedded in the cell cytoplasm and they are designated as organelles in a cell.
Endoplasmic reticulum, Golgi apparatus, mitochondria, ribosomes, microtubules, lysosomes etc. are the specialized organelles present in cell.
Each of these organelles perform specific function. For instance, mitochondria help in energy production, Golgi helps in protein modification and packaging.
Cell organelles are thus important structural and functional elements of a cell.

1. Which is the correct order of the stages of the cell cycle? *
Cytokinesis, Mitosis, Interphase.
Cytokinesis, Interphase, Mitosis
Mitosis, Cytokinesis, Interphase
Interphase, Mitosis, Cytokinesis
my best guess would be
→ Interphase, Mitosis, Cytokinesis ←
Explanation:Interphase - stage where the cell prepares for Mitosis. During this stage the cell grows and replicates DNA.
Mitosis - part where the chromosomes are separated and are separated into 2 nuclei.
Cytokinesis - part where cells officially splits into two daughter cells.
Cell cycles are events that involve various series of steps for the cell to grow. It follows the order of interphase, mitosis, and cytokinesis. Thus, option D is correct.
What is the cell cycle?The cell cycle is an important part of the growth and cell division of the eukaryotic cell. It includes interphase comprising the G₁, S (synthesis/replication), and G₂ phase, mitotic phase, followed by cytokinesis and G₀ phase.
The cell spends the majority of its time in interphase where the genetic material undergoes preparations and gets duplicated for the further process. In mitotic division the actual division of the organelles and the nucleic acid takes place.
Mitosis is followed by cytokinesis where the cytoplasm of the cell gets separated to form two daughter cells after the telophase stage. The cell then undergoes the G₀ phase which is the quiescent stage of the cell division where no cell division occurs.
Therefore, option D. interphase, mitosis, and cytokinesis are the correct order of the cell cycle.

Cell organelles have different functions that help maintain homeostasis within the
cell. The processes of photosynthesis and cellular respiration depend on these
organelles working properly. Identify the letter of the organelle whose function is to
store water and dissolved salts?
The function of the vacuole is to maintain the turgid pressure that is to maintain the cell turgidity. It stores water along with the dissolved salts in it. The answer is option B.
What are the other parts that are present in the structure of vacuole ?There are various enzymes that are present in the vacuoles and it is just like the pool of the plant cell which stores the various enzymes along with the water molecules and the dissolved salts.
With its roles that perform or help in the plant cell function that are the central vacuole which stores salts, minerals as well as nutrients, along with proteins and pigments that helps in the plant growth and plays important structural kind of role for plant. The organelle that is the central vacuole of plant cells that helps it to just maintain the volume along with the structure.
Vacuoles store the materials like water along with salts and proteins as well as the carbohydrates. Most of the plant cells that are having a single or the large central vacuole. The function of them is that they just store the salts with the sugars with few type of proteins and even the plant colors. They are even working as the storage bags for cell.

In shorthorn cattle, when a red bull (RR) is crossed with a white cow (WW), all the offspring are roan—a spotted, red and white color. What offspring are expected from mating a roan bull and a roan cow?
Answer:
25% red
50% roan
25% white
Explanation:
When RR (red) is crossed with WW (white), it results in roan color.
RR (red) x WW (white)
RW (roan)
Two roan individuals are then mated.
RW x RW
RR RW RW WW
Offspring
1/4 RR - Red
1/2 RW - Roan
1/4 WW - White
Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.
