Answer:
Heredity is important to all living organisms as it determines which traits are passed from parent to child. Successful traits are more frequently passed along and over time can change a species. Changes in traits can allow organisms to adapt to specific environments for better rates of survival.

The macromolecule shown here is an amino acid because of the carbon that bears the amine group and the acid group.
<h3>What is a macromolecule?</h3>
The term macromolecules refers to those molecules that have a large molecular weight. They can mostly be found in biological systems and play various roles in the body
The macromolecule shown here is an amino acid because of the carbon that bears the amine group and the acid group. There are four elements present as follows;
- Carbon - 6
- Hydrogen - 14
- Nitrogen - 2

Answer:
I don't think there is enough information for me to answer this
Explanation:
Answer:
Used the C1V1 = C2V2 method for calculations
Explanation:
Component Calculation Volume of Stock to be added
FBS: 100*V1 = 10*25 2.5 mL
Glutamine: 200*V1 = 2*25 0.25 mL
Penicillin: 10000V1 = 100*25 0.25 mL
Streptomycin: 10000V1 = 100*25 0.25 mL
NB: C1 = Stock Concentration; V1 = Volume of stock required; C2 = Final concentration required; V2 = Final volume required
The order in which the earliest organisms evolved -
- Archaea and bacteria
- Protists
- Fungi and shell-less invertebrates
- Green algae
- Shelled Invertebrates
On the earth, various kinds of organisms evolve at different geological times, and on their evolution, they consider the oldest or youngest organisms:
- Archaebacteria and bacteria was the oldest living organism on earth was, they lacked a membrane-bound nucleus and cell.
- The protists evolved after the bacteria, they were multicellular prokaryotic organisms.
- Fungi and the shell-less invertebrate, much-developed organisms in terms of body organization and structure. These have membrane-bound, well-defined cell membranes, and a nucleus. They even had a tissue level of organization.
- Green algae evolve after protists which belong to the division Thallophyta of the plant kingdom. These are photosynthetic as they have chlorophyll in the cell.
- Shelled Invertebrates are the youngest organisms that evolved recently among these.
Thus, the correct order is -
- Archaea and bacteria
- Protists
- Fungi and shell-less invertebrates
- Green algae
- Shelled Invertebrates
