<h2>Question:-</h2><h3> Which structure is found in all animal cells?</h3>
<h2>Answer :- Centrioles </h2>
<h2>Explanation:- </h2>
- They are barrel shaped cell organelles only found in animal cell
- There function is to help in division of cell membrane by forming microtubules which help in division of chromosomes ( spindle fibres)
- They play role in arranging microtubules which act as endoskeleton of the cell
- They also help in formation of cell structure like cilia and filaments
A relationship in which two or more species benefit is called a mutualistic relationship.
Answer:
diffusion and osmosis
Explanation:
diffusion is the movement of molecules across the membrane from an area of high concentration to an area of low concentration occurring with or without the help of membrane protein. Osmosis is the diffusion of water molecules.
Anatomy: the study of body placement
Physiology: the study of how the body functions
Differ: How it functions vs. where something is located
Hello. This question is incomplete, you forgot to show the necessary experiment for this question to be answered. It is important to remember that you need to post the full question so that we can answer it as you deserve.
The experiment is shown in the figure attached below.
Answer:
The dependent variable is the intracellular signaling pathways in hepatocytes. The negative control would be the activation of different signaling pathways, through the similar regulation of carbohydrate metabolism by hepatocytes when cells are treated with growth hormone or insulin. The scientists continued the experiment for 240 minutes, because the hormones have different signaling times.
Explanation:
Dependent variable is one that is influenced by the independent variable and generates a result. In the case of the experiment shown in the figure below, we can see that scientists wanted to evaluate the influence of growth hormone and insulin, on the activation of intracellular signaling pathways in hepatocytes, the same or different. For this reason, we can see that the dependent variable was the intracellular signaling pathways in hepatocytes.
Negative control is a biological process that promotes a result contrary to the stimulus performed. With that, we can affirm that a negative control in the addition of hormones, would be the activation of different signaling pathways, through the similar regulation of carbohydrate metabolism by hepatocytes when cells are treated with growth hormone or insulin.
Finally, scientists decided to keep the experiment for 240 minutes, because different homorns, have different action times, so 240 minutes would be the ideal time for the two hormones to have acted and their results could be analyzed.
