The control variable is a group that serves as a baseline for comparision. The independent variable is not applied or only applied at a baseline level.
The independent variable is the covering of the ice with different materials. Because group 4 wasn't covered, it is the control variable.
The control group in this experiment is group 4, which remained uncovered.
In an experiment, the control group is the group that does not receive any treatment or manipulation. It serves as a baseline for comparison to the other groups. In this case, the control group is not covered with any material, which means it is not subjected to any additional factors that could affect the melting rate of ice.
By comparing the results of the other groups (group 1 covered in plastic, group 2 covered in paper, and group 3 covered in aluminum) to the control group, the researchers can determine the effect of different materials on the melting rate of ice.
I hope this helps you. :)

Answer;
- Sensory receptors
After receiving a stimulus, the sensory receptors send(s) signals to the appropriate area of the body.
Explanation;
-Sensory receptors are structures that reacts to a physical stimulus in the environment, whether internal or external. They are sensory nerve endings that receives information and conducts a process of generating nerve impulses to be transmitted to the brain for interpretation and perception.
-The sensory receptors include those for tactile sensations, such as touch, pain, and temperature, as well as those for vision, hearing, smell, and taste.
Answer:
Image result for How is cellular respiration, both anaerobic and aerobic
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.

Answer:
an objective summary of an article on plant and animal reproduction, it would be important to include key information such as:
1. Overview of plant and animal reproduction processes: Provide a general description of how plants and animals reproduce, including the different mechanisms and strategies involved.
2. Importance of reproduction for species survival: Highlight the significance of reproduction in ensuring the continuation and survival of plant and animal species.
3. Key factors influencing plant and animal reproduction: Discuss the various factors that can impact plant and animal reproduction, such as environmental conditions, mating behaviors, pollination, seed dispersal, and reproductive strategies.
4. Reproductive adaptations and diversity: Explore the diverse range of reproductive adaptations and strategies found in different plant and animal species, showcasing the remarkable variety of reproductive mechanisms in nature.
5. Implications for conservation and management: Address the relevance of understanding plant and animal reproduction for conservation efforts, ecosystem management, and addressing issues related to declining populations or endangered species.
Remember, the specific statements to include in an objective summary would depend on the content and focus of the article you are summarizing.
Explanation:
Answer:
Acquired traits are due to changes in the life style, injury, loss of body parts, disuse of some body parts. These are the traits which occur in the somatic cells. Changes in the somatic cells are not passed on to the offspring belonging to next generation. Hence acquired traits cannot be passed on to next generation.
