Answer:
D
Explanation:
Brain can create new connection between neurons.
Answer:
Explanation:
1- the purpose of blood flow-circulatory system- is to convey Oxygenated blood, oxygen bonded with haemoglobin in the RBC with Nutrients - and distributed these through the arteries and capillaries away from the heart, to reach the cells and tissues, and transported the wastes of theses cells and tissues , with C02 through the veins back to the heart and the kidney.
2. During diastole,deoxygented blood from the inferior and superior vena cavae entering the R.atrium, passes through the tricuspid valve into the Right Ventricle. Simultaneously, oxygenated blood returning through the pulmonary veins enters the left Atrium,emptied through the bicuspid valve into the Left.Ventricle.
During systole, the two ventricles contracts. The Right ventricle contracts, the pressure of the blood forces the tricuspid valve to close,and therefore de -oxygenated blood pushes the pulmonary valves to open and blood passes through the pulmonary artery to reach the lungs where exchanges of oxygen with carbon dioxide occurs.The blood is now oxygenated and returns to the left atrium via pulmonary veins.
Simultaneously, the left ventricle contracts,the oxygenated blood it contains forced the bicuspid valve to close so that blood is forced through the aortic valve to empty into the aorta into the systemic circulation,branches of the carotid artery supplies the heart from the aorta.
The Whole cycle continues.
Answer:
The correct option is d). The process is called interstitial growth.
Explanation:
The cartilage is composed of chondrocytes, which are located in small spaces called lacunae. Its function is to synthesize the extracellular matrix of cartilage. Its growth occurs through two processes: appositional growth and interstitial growth. When chondrocytes in lacunae divide and form new matrix, it leads to an expansion of the cartilage tissue from within, the process is known as interstitial growth, this happens because the young chondrocytes divide mitotically, forming a group called isogenous, while forming the matrix, each one separates, creating its own lacunae. As a result of the increase of chondrocytes and the secretion of the new intercellular matrix, it causes the cartilage to grow (expand) from within.
Answer:
Explanation:
I think answer should be the first one
The individual organisms that frame a population are additional or less equally spaced, spread every which way with no predictable pattern, or clustered in teams. These are called the uniform, random, and clumped dispersion patterns. Uniform refers to the evenly distributed population, random means random spacing and clumped shows the distribution in clusters.
Food supply and resources are directly proportional to a particular distribution pattern. Random distribution occurs when several pollen grains of some flowers were carried by wind or bees. These flowers will then bloom where they were scattered.
hope this um ... helps hehe ........
