Not always because there could be birth defects, mutations, or other variables.
Answer:
Plasmin
Explanation:
Plasmin is a serine protease also referred to as fibrin digesting enzyme, it is responsible for the dissolving or degradation of blood clot. The process by which plasmin degrades blood clot is called fibrinolysis. Note that plasmin (active) is formed from an inactive enzyme called plasminogen.
Answer:
Option C.
Scientist explain the incomplete fossil record because not all organisms become fossils. Processes like erosion and mountain building can change rock layers, causing fossils to be spread over multiple layers or destroyed.
Explanation:
- Fossils are the remains of organisms that are found on the rocks after they die.
- So, no one can be 100% sure about the complete fossil record because of the continuous process like erosion and other natural calamities.
- The sediment must cover any organism's remains to start the fossilization process to start. Most of the organisms start decomposing before this process can be executed.
a chemical landfill is where chemical waste is stored once it has been used
if it is secure it means that the waste cannot pollute the environment through water, air etc
Answer: d. mothering style affecting the developing brain
Explanation:
Epigenetics is the study of features or "phenotypes" which do not involve changes in the DNA sequence. Epigenetics is about how genes are expressed and used instead of the DNA sequence of the genes themselves.
The behaviour of a person's genes depends not only on the DNA sequence of the genes, but also on so-called epigenetic factors. Effects on genes from the external environment can affect disease, and some of these effects can be inherited in humans.
So, Mothering style which affects the brain development is an exampe of epigenetics which do not show any genetic feature.
Hence, the correct option is d.
