Answer:
A earthquake happens when rocks along the fracture slowly bend, then suddenly slip, which is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves or you could just say its a seismic event
The answer is D.
If not sorry
(1) wave frequency is the number of waves passing a point at a certain time. Usually, this is expressed in a unit of 1/s or Hz.
f = (600 waves) / (8 hours x 3600 seconds/1 hour) = 1/48 or 0.02 Hz
(2) wave period, T = 1/f
T = 1/48 Hz = 48 s
(3) wave speed
speed = (600 waves)(3 ft/1 wave) / 8 hours
= 225 ft/h
Answer:
A) Dendritic cells and macrophages, although they are also found in other cells that belong, or not, to the immune system.
B) The innate immune response
Explanation:
The immune system is equipped with specialized receptors for the detection of pathogens such as bacteria or viruses, which are called receptors that recognize patterns (PRRs). These proteins are a key element in the innate system and are expressed primarily in antigen presenting cells, such as <u>dendritic cells and macrophages, although they are also found in other cells that belong, or not, to the immune system.</u>
<u>
The innate immune response</u> begins with the recognition of highly conserved molecular structures and present in large groups of microorganisms called 'molecular patterns associated with pathogens' (PAMP). This recognition is done by the 'pattern recognition receptors' (RRP) of the host.
The best known bacterial PAMPs are:
Lipopolysaccharides (LPS)
Peptidoglucan
Lipoteic Acids
Mananas (Mannose
)
Bacterial DNA
Double stranded RNA
Glucans
These PAMP are essential for the survival and pathogenicity of bacteria.
Answer:
Catabolite repression
Explanation:
Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.
It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:
- sensory systems-detects ratios of glycolytic intermediates,
- global regulators-control the expression of genes that encode for enzymes.
