Answer:
Mendel's first law of Segregation of Gametes says that "The alleles of a given locus segregate into separate gametes during meiosis"
Explanation:
The two alleles of a gene pair separate from each other during the process of meiosis and each gamete have an equal probability of producing either allele of the gene.
One parent pea plant is homozygous for inflated pods and green (suppose GGII) which is dominant in nature. Another parent pea plant is homozygous for deflated pods and yellow (suppose ggii) which is recessive in nature.
•) Then both the homozygous parent plants (GGII and ggii) which are dominated and recessive are crossed.
•) The gametes which will be obtained are GI and gi.
•) The resultant progeny is heterozygous with dominant traits GgIi.
Answer:
endocrine control, because melatonin is secreted into the blood and regulates body processes
Explanation:
Answer:
D. A waxy coating on a plant
Explanation:
A cuticle can be described as a waxy covering which preserves or protects certain parts of plants like leaves, shoots etc. Lipid molecules which are saturated with waxes make up the cuticle. Cuticle majorly functions in stopping the evaporation of water from the cell's epidermal layers. All the species of plants possess this waxy coating of cuticle because it plays important role in stopping the loss of water from the cells.
Answer:
Explanation:
The molecular and cellular mechanisms and processes that explain muscle contraction in striated muscle occur in the myofibril sarcomere. Their understanding depends on the organization's understanding of the structure of the sarcomere. In an imaginary experiment we first assemble an ideal sarcomere.
Remember that the myofibril is a set of cylindrical compartments that are located next to each other, constituting an elongated cylinder. Each of these cylinders is a sarcomere and borders its neighbor on a line or band called, line or band z.
On each side of the z line, thin cylindrical filaments that are actin filaments are inserted. Each actin filament is formed by a double strand of actin molecules that are rolled over each other. In this organization, actin is called actin F.
