Answer: I believe the Lateral Lines are made of mechanoreceptors called neuromasts....
I know that hair cells, like the ones inside a human ear, are used as well.
Is chemistry for reactions to take place energy must be provided. As heat is a form of energy, the more the heat, the more the energy, the faster the reaction occurs
Answer:
Each one has two fatty acid chains and the glycerol backbone is bonded to a small polar group.
Explanation:
Phospholipid is a unique form of lipid. The bonding of the glycerol backbone to the polar phosphate group makes phospholipid to have dual solubility unlike general triglycerides.
The polar head is said to be hydrophillic that is <u>water loving,</u> while the two carbon chains that retained lipid features are hydrophobic <u>water hating.</u>
Therefore if a phopholipid is placed in water, in relation to its functions as component of cell membrane, it forms a bi-layer in which the water loving portion hydrophilic head points into the surrounding watery medium, while the hydrophobic layer points inwards far away from the watery medium into the internal cellular layer to form an impermeable barrier to hydrophilic (polar) substances.
This forms the basis of the phospholipd bilayer of the cell membrane. And it controls the permeability of the cell membrane to influx substances into the cells.
Answer:
1) Recursive definition: 
2) At the beginning of the 4th interval
Explanation:
1)
The initial population of the bacteria at time zero is
Here we are told that the reading is taken every two hours; we call this time interval "n", so
And also, after every time interval n, the number of bacteria has tripled.
This means that when n = 1,
And when n=2,
Applied recursively, we get
And substituting p0,
(1)
2)
Here we want to find at the beginning of which interval there are
bacteria.
This means that we can rewrite eq.(1) as
By simplifying,
Which means that
However, this means that the number of bacteria is 1,350,000 after 3 time intervals; therefore, at the beginning of the 4th interval.
Answer:
These facts are true and disturbing
Explanation:
Genetics is a discipline that has advanced incredibly in the last years. For example, by using the versatile CRISPR-Cas9 genome editing system, we are now able to insert literally any sequence into a given genome in vivo. The CRISPR-Cas9 is a technology that can be used in a regular molecular biology laboratory. It is expected this technique will enable in the near future to correct genetic disorders that have plagued mankind since times immemorial. However, genomic technologies like that could be used by malignant persons to hurt innocent people, thereby it is imperative that countries regulate their use.
