Explanation:
Which of the following organelles are found in plant cells? Select all that apply.
A: cell wall
B: nucleus
C: central vacuole
D: flagella
E: lysosomes
Answer:
cell wall, central vacuole, and nucleus
Explanation:
The organelles that are found in plant cells are the cell wall, nucleus, and central vacuole. The correct options are A, B, and C.
What is a plant cell?Plants cells are the cells present in plants. These cells are the same as the animal cell, but they contain a cell wall and the animal cell does not contain a cell wall.
Plants cells also contain vacuole which is filled with water, that is missing from the animal cells. They are eukaryotic cells and these cells also contain a nucleus that is the brain of the cell.
The cell wall is made up of cellulose, filaments, and pectin protein. It gives the plant cell rigidity and protection. The vacuole is filled with water.
Thus, the correct options are A, cell wall, B, nucleus, and C, central vacuole.

In a well-structured paragraph, evaluate the experimental design of the investigation into the osmolarity of different types of apples for adequate controls and measurement techniques .
Answer:
To determine the osmolarity of two types of apples in this experiment they use four sucrose solutions and twenty-four apple cylinders. They let these cylinders stand overnight in separate beakers of sucrose solutions, and repeat the procedure for the second variety. For the first variety, they record the temperature for the sucrose solution and remove the core to determine their combined mass. Then they will record the final masses and calculate percent change by using the percentage change in mass formula. After, they repeat these same steps for the second variety.

How long ago do scientists believe the continents formed Pangaea?
about 135 million years ago
about 180 million years ago
about 300 million years ago
about 4.5 billion years ago
The scientists believe the continents formed Pangaea about 300 million years ago. The correct option is C.
What is Pangaea?According to National Geographic, the Pangaea theory proposed that the tectonic plates that make up the planet's external crust glided over the inner layers until they consolidated as a landmass encircled by a huge ocean called Panthalassa.
After a while, the Angaran continent near the North Pole began to move south and combined with the northern part of the expanding Euramerican continent, forming the Pangea supercontinent. This process was completed approximately 300 million years ago.
Alfred Wegener observed the same thing in 1912 and proposed that the continents were once scaled down into a single protocontinent known as Pangaea.
Thus, the correct option is C.

When viewing a specimen in a microscope, which parts allow you to physically SEE the image?
stage
eyepiece Only
objective only
eyepiece and the objective
Answer:
When viewing a specimen in a microscope, what allows to physically see the image are both lenses, eyepiece and objective.
Explanation:
In optical microscopy, the lenses used to observe microscopic samples play an important role and are necessary for the study of such samples.
- An objective lens is the first to capture the image, providing clarity and proper focus, as well as eliminating color or shape distortions.
- Eyepiece lens obtains the image provided by the objective lens and enlarges it, so that the observer can appreciate the characteristics of the specimen studied.
Regarding other options:
Stage allows to see the prepared sample, ready for its study, but the microscopic characteristics are not appreciated. The eyepiece and objective work together to provide a proper microscopic image.Describe a form of energy transformation that occurs in Earth's atmosphere.

A structure that performs a specialized function within a cell is known as
A) a tissue
B) an organ
C) an organelle
D) a system
A structure that performs a specialized function within a cell is known as is system.
What is system?Humans and other sophisticated multicellular organisms have coordinated organ systems that perform the functions necessary to sustain life.
The body is organized at many stages that progress together. Organ systems are made up of tissues, which in turn are made up of tissues and organs.
The coordinated activity of an organ system's organs determines how well it functions. In sophisticated multicellular animals like people, the cells are arranged into tissues, which are collections of comparable cells that collaborate on a particular activity. Organ systems are collections of organs with connected.

Asexual Reproduction occurs when there is only one parent that gives rise to an offspring which has the identical genetic makeup of the parent. It occurs in most single celled organisms such as bacteria and some multicellular organisms such as fungi and some plants. Some advantages of asexual reproduction are it is fast and efficient. It does not require a male and a female. Organisms can reproduce quickly! A disadvantage is that there is no genetic diversity and it can only be done by simple organisms.
Sexual Reproduction involves the combining of genetic information from two parents to produce a new organism that is a combination of both parents. It occurs in most complex organisms. Some advantages to sexual reproduction are that it creates genetic diversity. It allows for evolution of the species. A disadvantage is that it requires two organisms to reproduce, a male and a female. It also requires more energy than asexual reproduction.
Using the table below, list at least two advantages and disadvantages of Asexual and Sexual Reproduction.

How does the cell membrane help maintain health in life
Answer:
The cell membrane controls the substances that enter and exit the cell
Explanation:
The cell membrane defines the boundaries of the cell, separating the internal components from the external environment.
The membrane is a semi-permeable barrier that lets some substances in and out, but not others.
Therefore, the cell membrane controls many of the activities of the cell. As a result, it is crucial to maintain the normal functioning of the organism

Does respiration expend more energy than photosynthesis?
Answer:
Explanation:
Photosynthesis vs Cellular Respiration Photosynthesis and cellular respiration are two basic metabolic processes occurring in the energy conversion of ecosystems. During photosynthesis, carbon dioxide and water are used in the synthesis of organic compounds with the aid of sunlight. This organic compounds can be used by cells as food. During cellular respiration, energy in the form of ATP is produced by breaking down food. The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.

Identify the names, labels, and roles of three eukaryotic organelles that are involved in the transport, packaging, and export of a protein synthesized on a bound ribosome in this cell.
Answer:
Three eukaryotic organelles that are involved in the transport, packaging, and export of a protein synthesized on a bound ribosome in this cell are -
Endoplasmic reticulum Golgi bodiesRibosomesExplanation:
ENDOPLASMIC RETICULUM - The endoplasmic reticulum ( ER) is a broad, dynamic structure that serves many cell functions, including the storage of calcium, protein synthesis and metabolism of lipids. Separate regions, consisting of tubules, sheets and the nuclear envelope, perform the diverse functions of the ER.GOLGI BODIES -: A membrane bound organelle found in most cells is the golgi apparatus. Before secretion, it is responsible for packaging proteins into vesicles and thus plays a key role in the secretory pathway.RIBOSOMES -: The organelles which aid in protein synthesis are ribosomes. For many cell activities, protein is necessary, such as damage repair and other chemical processes.A ribosome is composed of two subunits:
the small ribosomal subunits- these read the mRNA. The large ribosomal subunits - form amino acid polypeptide chains.Hence , the labelled diagram of eukaryotic cell is attached below.
