Answer:
Autonomic regulation of heart is via two reflex centers that are found in medulla oblongata
Explanation:
Medulla oblongata contain long stem that makes the upper part of brain case and this is a cone shaped structure which is responsible for autonomic regulation like controlling heart rate,vomiting,respiration,breathing etc.
The heart rate is controlled by autonomic nervous system that are mainly sympathetic and parasympathetic nervous system that releases hormones like catecholamine (epinephrine and non epinephrine) which helps in controlling the heart rate.
Medulla oblongata mainly connects the brain with the spinal cord that are responsible for responsible for the autonomic functions which contain -
Controlling the ventilation via signalling system regulated by chemo receptors which detects change in acidity of the blood.
Acts on cardiovascular centers.
Controlling the reflex centers like vomiting,coughing,sneezing,swallowing etc.
The correct answer is the G2 phase. The G2 phase is usually the shortest of the three phases pf interphase. During G2 phase, many of the organelles and molecules required for cell division are produced. When the G2 phase is completed, the cell is ready to enter Mitosis and begin cell division. Hopes this helps!
Answer:
In humans, implantation is the stage of pregnancy at which the embryo adheres to the wall of the uterus. At this stage of prenatal development, the conceptus is called a blastocyst. It is by this adhesion that the embryo receives oxygen and nutrients from the mother to be able to grow.
Explanation:
The answer is hyperosmotic urine.
A counter current mechanism system refers to a process, which spends energy to produce a concentration gradient. It is witnessed broadly in nature and mainly in mammalian organs. For example, it can signify towards the process of urine concentration, that is, the generation of hyperosmotic urine.
The hyperosmotic urine exhibit greater osmolarity in comparison to the blood. The kidneys generate hyperosmotic urine in response to a deficiency of water as an effort to return to homeostasis.
