Answer:
SRY
Explanation:
Sex determination in mammals including humans is genetically and hormonally controlled.
Genetically gonadal sex determination is mediated by a gene called SRY. This gene is known as the mammalian Y-chromosomal testis-determining gene. It induces sex determination in males.
Recent studies revealed that SRY plays an important role in inducing Sertoli cells differentiation. The Sertoli cells, in turn, guide testis formation.
Therefore, in males, differentiation of testis is switched on by expression of the Y-linked SRY gene.
Answer:
The correct answer is - lower survival rate for caterpillars and butterflies. (assuming it is one the option)
Explanation:
The decision to stop the spraying the pesticides that control lawn pests in this butterfly project. The native plants and grass begin to invade again mostly native that increase the number of resources for the pests.
The availability of enough resources is to increase the chances and rates of the pests like caterpillars and butterflies.
Thus, the correct answer is - lower survival rate for caterpillars and butterflies. (assuming it is one the option)
Breathing/movement, animals
Answer:
A
Explanation:
Mitochondria are well known as the powerhouse of the cell, and as discussed in the section on Generation of ATP: Bioenergetics and Metabolism, in an active tissue such as heart, they are responsible for generating most of the ATP in the cell.
Explanation:
- Carbon has 4 valence electron means it can form covalent bonds with 4 different elements per carbon atoms
- Carbon can bond with itself to form long chains
- Carbon can form single, double and even triple bonds with other elements including other carbon atoms.
- Carbon atom has a small size to fit in comfortably as parts of very large molecules.
