Answer:
The vessels draining Myocardium of the heart join to form <u>Coronary Sinus </u> that ultimately opens into <u><em>THE RIGHT ATRIUM.</em></u>
Explanation:
<u><em>CORONARY CIRCULATION:</em></u>
The heart muscles are called as Myocardium. Circulation of myocardium is known as Coronary Circulation. The heart needs to work continuously and requires an uninterrupted supply of blood.
<u>Coronary Arteries</u> supply oxygen rich blood to the myocardium and <u>Coronary Veins</u> remove deoxygenated blood from heart muscles and join to form Coronary Sinus that ultimately drains into the Right Atrium of heart. Some veins from the myocardium also drains directly into the right atrium.
Answer:
Motor protein kinesin can "walk" along a microtubule while carrying vesicles and by changing its shape the kinesin.
Explanation:
Motor protein kinesin is an important microtubule based motor protein that is conserved among all eukaryotic organisms. Its movement along the microtubule is ATP powered. Most of the kinesins walk towards the plus end of the microtubule.
Due to its ability it is responsible for unidirectional transportation of cargos including membranous organelles and mRNA.
mitosis has 5 different stages: interphase, prophase, metaphase, anaphase and telophase.
the process of cell division is only complete after cytokinesis, which takes place during anaphase and telophase

Answer:
Carbon dioxide moves in; oxygen moves out
Explanation:
The pigment that offers the green pigmentation for green plants is known as Chlorophyll. On the surface of the leaves on green plants are microscopic openings known as Stomata in the epidermis of leaves. Stomata are generally more numerous on the underside of leaves. They provide for the exchange of gases between the outside air and the branched system of interconnecting air canals within the leaf.
On a sunny day, The concentration of carbon dioxide in the air is a regulator of stomata opening in many plants. The stomata opens (then Carbon dioxide moves in and in-turn releases oxygen after photosynthetic activities has taken place) and closes in response to the internal pressure of two sausage-shaped guard cells that surround it. The inner wall of a guard cell is thicker than the outer wall.
The main function of these Guard cells are to control excessive water loss, closing on hot, dry, or windy days and opening when conditions are more favourable for gas exchange.
