Answer:
When an E.coli cell is infected by multiple phages,they will take either lytic or lysogenic pathway.
Explanation:
When lambda phage bacteriophage infects an E.coli,it can either undergo lytic cell growth and lyse the host cell or enter lysogenic pathway.
The operator region of lac operon in E.coli contain single repressor binding site whereas the lambda operators 
and 
each contains 3 repressor binding sites (
and 
) that are differently occupied under different conditions.
The differential affinity of lambda repressor for the three binding sites in these operators play an important role in the maintenance of lysogenic state of lambda prophage in E.coli.
The lytic development occurs in cells infected with lambda phage that carry 
gene.
In contrast,lysogeny will occur in bacteria that infected with lambda phage that harbor a deletion of Cro gene.
Answer: Her acceleration is -0.8 m/s²
Explanation:
The initial velocity of Sandra ( u) = 10 m/s
The final velocity of Sandra ( v) = 2 m/s
Time taken by Sandra (t) = 10 s
Let the acceleration of Sandra be 'a'
Using the equation of kinematics, we have
v = u + at
⇒ 2 = 10 + 10a
⇒ -8 = 10a
⇒ 
⇒ a = -0.8 m/s²
Hence, her acceleration is -0.8 m/s².
Answer:
A and C
Explanation:
X-linked recessive diseases are disorders caused by a mutation on the X chromosome causes the phenotypic expression in males and only when it is homozygous for females.
A small percentage of women can display the disease phenotype on rare phenomenon such as;
- X-inactivation that favors inactivation of the normal X chromosome
- Turner syndrome (a sex-chromosome aneuploidy in which women have only one X chromosome)

<h2>
Answer:</h2>
Option D) proteins, starches, and fats.
<h2>
Explanation:</h2>
- Organic compounds are compounds that contain Carbon(C) and contain Hydrogen(H) as well.
- Water, H₂O does not contain carbon is therefore it is not organic compound .
- So option A) and B) can be eliminated since they contain water.
- Carbon dioxide, CO₂, contains carbon but doesn't contain hydrogen, and therefore we can eliminate Option C) as well.
- This leaves Option D) i.e proteins, starches and fats are organic compounds, all of them are organic compounds.
Result: Option D) is the correct answer.
