Answer:
Gender schema
Explanation:
<em>The cognitive organization of the world accroding to male and female is referred to as gender schema.</em>
<u>More specifically, gender schema is an organized set of gender-related beliefs that dictates how an individual behaves in a society.</u>
The gender schema theory was developed by Sandra Bem in 1981 and it explained that the formation of basic gender identity by children makes them to develop gender schema in relation to how they interact and observe others as well as their environment.
Answer:D
Explanation: hope this helps
Answer: Lac operon
Explanation: the same cells when grown in glucose media utilize the glucose as source if energy by blocking the activity of the enzyme beta- galactosidase. the operator site of the operon is blocked thereby preventing the activity of the collective functional genes.
Answer:
Explanation:
Bacterial count in stock- 1.85x10^6 cfu/ml
Dilution methods
Take 100 uL or (0.1ml) from stock and add to 900ul (0.9ml) saline and mixed it- this makes 10^1dilution.
Now take 100ul from 10^1 dilution and add to next 900ul saline this is 10^2 dilution, similarly do upto 10^5 dilution.
Then take 100ul from 10^ 4 and 10^5 dilution seperately and plate on LB agar plate seperetely and count the colonies.
Cfu/ml formula= (No.of colonies x dilution factor)/0.1 ml
So suppose, 18 colonies formed on 10^4 dilution then total no. Of cells in stock will be 18x10^4/ 0.1= 18x10^5 cfu/ml.
If we dilute 10^4 or 10^5 that's leads to colony count of 18-19 colonies on 10^4 dilution while 2 colonies should come on plate of 10^5 dilution.
Answer: give new gene sequences to the host bacteria.
Explanation:
Bacteriophages are viruses that infect bacteria. Viruses are the most numerous organisms on earth and play functions in the biotic component of virtually every ecosystem. They are distinct biological entities and the main feature of this group is the dependence on specific hosts for reproduction, hence known as obligate intracellular parasites. In the lysogenic cycle, phage nucleic acid recombines with that of the bacteria forming a prophage and replicates in the host cell from one generation to another without cell lysis. By doing this, the bacteriophages give new gene sequences to the host bacteria, contributing to bacterial virulence.
