Answer:
Explanation:
The P cross produces F1 offspring that are all heterozygous for both characteristics. The resulting 9:3:3:1 F2 phenotypic ratio is obtained using a Punnett square.
Answer:
d. Epinephrine
Explanation:
The adrenal glands which are located at the top of each kidney are made up of two parts: the cortex and the medulla.
The adrenal cortex is the outer part of the adrenal gland, while the inner part is the adrenal medulla.
The adrenal medulla has tissues that are composed of popstganglionic sympathetic nervous system neurons which are involved in stimulating the medulla to secrete the epinephrine and norepinephrine hormones.
Epinephrine functions to increase cardiac output and increase level of glucose in the blood when the body is exposed to threat or stress.
The answer is <span>D) the second filial generation, or the "grandchildren" of the original mating pair.
In a monohybrid cross, the original mating pair is called a parental generation (P). The offspring of parental generation is the first filial generation (F1). The offspring of the first filial generation (and the "grandchildren" of the original mating pair) is called the second filial generation (F2).</span>
Answer:
1. Muscle: soft, contractile tissue important to produce force and motion in animals.
2. Fascicle: multiple bundles of skeletal muscle fibres which is surrounded by a type of connective tissue called perimysium.
3. Muscle fibres: bundles of cylindrical organelles myofibrils formed by the fusion of myoblasts via myogenesis process.
4. Myo-fibril: basic unit of a muscle cell made of thick and thin myofilament arranged in parallel columns along the length of muscle fibres.
5. Myo-filament: strands of actin and myosin proteins which pack a muscle fiber and are force generating structures.
