Myosin and actin protein filaments attach to each other . Calcium ions release into myofibrilles . Myosin filaments pull on the actin filaments
Answer:
1/2
Explanation:
Assuming the gene is represented by the allele G (dominant), the alternate form (recessive) of the allele will be g.
A heterozygous pea plant will have the genotype Gg. During gamete formation, Gg will split into G and g gametes.
<em>The probaility that a gamete will contain the recessive allele for flower color is 1/2.</em>
Sunlight is the source of energy because producers such as grass and trees use photosynthesis to make energy from sunlight. Grass and trees are then eaten by animals like cows, chickens, and pigs. The animal takes in the energy it receives from the foliage, and humans in turn, receive energy from eating the livestock.
Answer:
Intramembranous ossification begins with differentiation of mesenchymal cells.
Explanation:
Fibrous membranes are involved in the development of the bones. The process through which this occurs is termed as the intramembranous ossification.
The cells of the mesenchyma begin to split. These cells differentiate into specialized cells each performing different functions. The following bones are formed by the process of intramembranous ossification:
- mandible
- clavicle
- some bones of the skull
