Answer:
lysogenic
Explanation:
Phages can generate the lytic cycle or the lysogenic cycle, although very few are able to carry out both. If lysis is carried out, lysogeny cannot be carried out and vice versa. In the lytic cycle, phage host cells are lysed (destroyed) after replication and encapsulation of viral particles, so that new viruses are free to carry out a new infection.
On the contrary, in the lysogenic cycle there is no immediate lysis of the cell. The phage genome can be integrated into the chromosomal DNA of the host bacterium, replicating at the same time as the bacterium does, or it can remain stable in the form of a plasmid, independently replicating bacterial replication. In any case, the phage genome will be transmitted to the entire progeny of the originally infected bacteria. The phage is thus in a state of latency until the conditions of the environment are deteriorated: decrease of nutrients, increase of mutagenic agents, etc. At this time, endogenous phage or phage are activated and give rise to the lytic cycle that ends with cell lysis.
Answer:
a. Type O blood - No A or B antigens on RBCs-Anti-A antibodies in plasma-Anti-B antibodies in plasma
b. Type A blood - A antigen on RBCs- Anti-B antibodies in plasma
c. Type B blood - B antigen on RBCs- Anti-A antibodies in plasma
d. Type AB blood - A antigen on RBCs- B antigen on RBCs- Neither anti-A or anti-B in plasma
Explanation:
ABO blood grouping system represents multiple allelism which was discovered in humans by Karl Landsteiner. The blood group is determined by the presence or absence of A & B antigens and antibodies.
The 4 blood groups which exist in ABO system are O, A, B and AB. Also, allele A and B are co-dominant i.e. if they both will exist on the surface of an RBC then both will be equally expressed which implies that there will be no dominant or recessive allele.
Type O blood group has H antigen on the surface of RBC and has both the antibodies i.e. antibody A and B. The absence of antigens A and B makes it a universal donor.
Type A blood group has A antigen on RBC and has antibody B in the plasma.
Type B blood group has B antigen on RBC and has antibody A in the plasma.
Type AB blood group has both the antigens i.e. antigen A and B on RBC and does not have any antibody in the plasma which makes it a universal acceptor.

Answer:
Cool water at the surface traps nutrients deep in the lake to provide food during the winter.
Explanation:
During winter, <u>ice forms on the surface of the lake</u> when the temperature drops below 4 degrees Celsius. However, the <u>water below remains warm</u> because the ice layer on top also acts as insulation of heat transfer in case of further temperature drops. Further, ice formation <u>retains/seals off</u> nutrients and gases flow below the ice sheet. The amount of nutrients is sufficient for phytoplankton activity during light hours (there is no complete darkness even after thick ice sheet is formed). Resultantly, the <u>photosynthesis</u> produces <u>oxygen and food</u> for aquatic organsism within the lake environment and support their <u>survival during winter season</u>.
