Answer:
<h2>Lytic cycle: involve that there is rupture( lysis) of the host cell and release many copies of virus.
</h2><h2>Lysogenic cycle: involve the insertion of the nucleic acid of a bacteriophage into host genome, known as prophage.
</h2>
Explanation:
There are many similarities and differences between lysogenic and lytic cycles that;
1. Lysogenic cycle of bacteriophage :
i) in lysogenic cycle: bacteriophage insert its DNA with that of a host, known as prophage and it replicates with host.
2. Lytic cycle of bacteriophage:
i) lytic cycle is that it results in many copies of the virus very quickly and the cell is ruptured and many copies of virus are released.
4. Similarity is that in both cycles bacteriophase inter into the host and use their machinery.
Dinoflagellate is a type of neurotoxin which is found in the red-tide algae.
The answer is:
d. people can get paralytic shellfish poisoning during dinoflagellate blooms
Dinoflagellate algal blooms, during red-tide, release strong neurotoxins that can be ingested by shellfish and passed on to humans who eat the infected shellfish. The most significant public health problem that has been known to cause this harmful algae poisoning is: Amnesic Shellfish Poisoning (ASP).
Since we were given only one point, we have to test each exponential function for the point
Since exponential functions are of the form
, The correct option is between option A and option C.
For option A,
On substitution, we have;
.
Since the point satisfied the exponential function
, the exponential function goes through it.
Hence the correct answer is option A.
No need to test for option C again.
Answer:
Most likely diagnosis is Basal Cell Carcinoma (BCC), most likely caused by years of prolonged exposure to sunlight over time.
Explanation:
Basal Cell Carcinoma (BCC) is a common type of skin cancer that develops when the basal cells that is responsible for producing new skin cells when they die, become mutated and causes the basal cell to abnormally multiply rapidly and continues to grow. The accumulation of these abnormal cells is what results in cancerous tumors that appears like ulcers on the skin. Prolong and intense exposure to the ultraviolet (UV) radiation from sunlight has been linked to the most likely cause for the mutation of the DNA in the basal cells which leads the abnormal cell growth and multiplication. People who expose themselves to the radiation of the sun for longer periods, over time, are at high risk of developing this cancer.
Answer:
<h2>1. unconditioned stimulus, </h2><h2>2. loud noise</h2>
Explanation:
Such type of stimulus that is trigger by the neutral in nature is called a conditioned stimulus such as the sound of the bell and some other. Such type of stimulus that is biologically potent is called an unconditional stimulus such as the taste of food and some other things. When the biologically effective stimulus is used with neutral stimulus then the classical conditions are formed that are used in the learning process.
