Answer: D
Explanation: Because The Chloroplast is the Gate to move waste out of the cell and nutrients into the cell. Most plants do not contain a cell membrane.
Animal cells have a chloroplast and plant cells don't have a chloroplast because plant cells uses the chloroplast to produce energy from the chloroplast. So, option B, i.e., plant cells need chloroplast to make food because plant cannot move to get their food on their own, is correct.
The plants produce energy or their food with the help of a process known as photosynthesis.
The chloroplast is a green colored cell organelle which is responsible for carrying out photosynthesis.
In the photosynthesis, the light energy from sun is converted into chemical energy which is utilized as food by the plant.
Therefore, option B, plant cells need chloroplasts to make food because most plants cannot move to get food on their own.

C)chemical change
D)physical change
The color is one among the B) physical properties.
The physical properties are visible or observable. The physical properties are measured with physical system. There are many physical properties which include color, size, radiance, luster, and so on. There are two types of physical quantities which includes intensive property and extensive property. This property depends on the change in the structure of the material.
The color of the substance depends on the color it is observing and illuminating which depends on the reflective property of the substance.
The color of ink is basically a physical property. The correct option is B.
Ink's colour is a tangiblecharacteristic. A substance's physical attributes are traits that may be seen or quantified without affecting its chemical makeup. Ink's appearance is referred to as its colour, which is determined by how it responds to light.
There are no chemicalreactions taking place, and the ink's chemical makeup does not change because it is an inherent quality of the ink itself.
Colour, smell, density, melting point, boiling temperature, and other qualities are examples of physicalproperties.
In the case of ink, the colour is a physical characteristic that aids in differentiating and identifying various types or ink formulations.
Thus, the correct option is B.

The mass of the products equals the mass of the reactants because the same matter is present.
The mass of the products equals the mass of the reactants because there is no energy involved in the reaction.
The mass of the products is less than the mass of the reactants because energy is given off by the reaction.

Answer and Explanation:
The human being has a bone system made up of 206 bones that grow and develop in childhood and adolescence. Thanks to these bones, people can stand up and move around. The function of the bone system is to support the body, allow locomotion, and protect the organs. The bones that make up the system are linked through joints and are made up of a class of cells known as osteocytes.
The bones form various cavities that protect the internal organs from possible trauma. For example, the skull protects the brain from hits, and the rib cage, made up of ribs and sternum, protects the lungs and heart. On the other hand, various minerals such as calcium and phosphorus are stored in the bones, not only to provide them with hardness, but to later use them as an input in muscle contraction and other organic processes
B. lakes
C. rivers
D. ponds
Answer:
The correct answer is A. Marshes. :)
Explanation:
An example of a wetland ecosystem would be marshes, as they are regions where water is the primary factor controlling the environment and the associated plant and animal life. Lakes, rivers, and ponds are examples of aquatic ecosystems, not wetland ecosystems.
The correct answer to your question, 'Which of the following would be an example of a wetland ecosystem?' is marshes (option A). Wetlands are regions where water is the primary factor controlling the environment and the associated plant and animal life. They occur where the water table is at, or near the surface of the land. Different types of wetland ecosystems include marshes, swamps, and bogs.
Marshes, specifically, are a type of wetland where vegetation is dominated by herbaceous plants. Lakes, rivers, and ponds (options B, C and D respectively) are all instances of aquatic ecosystems, rather than wetland ecosystems. Lakes and ponds are standing or lentic waters, while rivers are flowing or lotic waters.
