Answer:
Explanation:
Medicines are chemicals or compounds used to cure, halt, or prevent disease; ease symptoms; or help in the diagnosis of illnesses. Advances in medicines have enabled doctors to cure many diseases and save lives.
Answer:
2.447 × 10⁴ years
Explanation:
Step 1: Given data
- Half-life of the radioactive atom (t1/2): 3,500 years
- Parent-daughter ratio ([A]/[A]₀): 1:127 (1/127)
Step 2: Calculate the rate constant
Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.
k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹
Step 3: Calculate the time elapsed (t)
For first-order kinetics, we will use the following expression.
ln ([A]/[A]₀) = -k × t
t = ln ([A]/[A]₀)/ (-k)
t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y
Ftsz, mreb, and cres ,proteins regulate the shape and structure of bacterial prokaryotic cells. These proteins are homologous to the Cytoskeleton in eukaryotes. Homologous meaning they have the same evolutionary origin but not necessarily having the same function. Cytoskeleton forms a framework for the movement of organelles around the cytoplasm, most organelles are attached to the cytoskeleton.
Minerals must have a definite chemical composition which may differ within specified limits. According to geologists minerals must be:
<span>>naturally occurring-meaning, people did not make it.
>inorganic- means not made by an organism
>solid-not a liquid, not a gas at standard temperature and or pressure
>definite chemical composition-</span><span> all occurrences have a chemical composition which varies within a specific limited range.</span><span>
>ordered internal structure-</span><span> meaning, atoms are arranged in a systematic and repeating pattern.</span>
It will reproduce through Binary Fission. The bacteria will replicate all of its DNA, then divides into two parts and gives each new organism a copy of the DNA
