The answer would be skeletal markers and DNA analysis.
Skeletal markers are often used to identify the biological gender of skeletal remains. The most commonly used skeletal markers can be observed in the skull and in the pelvic bone.However, the accuracy of his method is limited to adults only the differences between male and female skeletal markers usually become visibly only after maturation.
DNA analysis is more widely uses nowadays because with the technology of today, laboratories can now detect and X and Y chromosome-specific sequences, which help them identify the biological gender.
Answer:
it also can provide good fertilizer as well
Explanation:
The answer is Charles Darwin. He was the first to theorize evolution from a common ancestor.
The nitrogen in the air cannot be used by producers and consumers. It must be fixed or converted by bacteria in the ground into a useable form for plants called nitrates. Some plants called legumes (beans and clover) actually have bacteria in their roots.
Answer:
-20 kcal/mol (It stays the same)
Explanation:
Enzymes will reduce the Gibbs free energy of activation, but will neither increase or decrease the free energy of reaction.
Enzymes means of activity is by decreasing the activation energy (Ea or ΔG✳) for a reaction. This in turn raises the reaction rate.
Free energy of reaction
= free energy of product - free energy of substrate
The free energy of the product remains constant even without the enzyme. Hence, the enzyme would show no effect on the free energy of the reaction.
The attached image shows the effect of changes in enzyme concentration on the free energy.
