Answer:
Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.
C. Bats and dolphins probably share an ancestor from millions of years ago
Answer:
The correct answer is i forgot to label the probe with a reporter molecule.
Explanation:
Reporter molecule is a specific type of molecule that reports the success of cloning.
In this experiment to test the presence of N gonorrhoeae by using the DNA probe that was developed by me should be at first labelled probe sequence with a reporter gene such as lucciferase protein.
When this reporter molecule labelled DNA probe will bind to the target DNA sequence of N gonorrhoeae at that time by using the substrate specific for that reporter molecule will help me to notice the process of hybridization.
Answer:
two
Explanation:
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses.
Answer:
Answer is A. allow them to control all the variables involved.
Explanation:
Modelling in ecology means the use of constructed mathematical models for understanding of ecological processes and to predict or know how real it is for ecosystem to change.
Ecological modelling is useful in defining problems more precisely and clarity of concepts.
