Answer:

28

Explanation:

Binary Fission basically means each bacteria splits into two. So after the first two hours, the 7 bacteria split into 14. After the next two hours, the 14 bacteria each split and the end result is 28 bacteria.

Consider a cell in which Cl- distributes passively across the membrane according to the membrane potential. The resting membrane
UNO [17]

Answer:

1000 mM

Explanation:

Using V = -60 mV㏒₁₀[K/K'] where V = membrane potential = -60 mV, K = intracellular concentration = unknown and K' = extracellular concentration = 100 mM

So, V = -60 mV㏒₁₀[K/K']

-60  mV = -60 mV㏒₁₀[K/K']

dividing both sides by -60mV, we have

-60  mV/-60 mV = ㏒₁₀[K/K']

㏒₁₀[K/K'] = 1

taking antilogarithm of both sides, we have

[K/K']  = 10¹

multiplying both sides by K', we have

K = 10K'

K = 10 × 100 mM

K = 1000 mM

So, the intracellular Cl- concentration is 1000 mM

Explain the term "molecular clock" and describe the types of measurements and comparisons that can be made with this type of clo
arsen [322]

Answer:

In biology, a molecular clock can be described as a method to determine the time for the divergence of species which occurred by the process of evolution.

Explanation:

The mutation rates of different molecules are used in this method. The mutation rates for DNA sequences and amino acid sequences are usually considered. The molecular clock can be used to compare and estimate the splitting of a lineage. For example, by this method, one can interpret when the chimpanzees and humans diverged from each other.

Hope this helped!

Proteins are important biomolecules. Proteins are synthesized and often packaged for secretion into other cells within an organism. A variety of organelles play a role in producing, packaging, and moving proteins.

Organelles of Eukaryotic Cells

Organelle Function

Nucleus The “brains” of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA.

Mitochondria Make energy out of food

Ribosomes Make protein

Golgi Apparatus Make, process and package proteins
