Out of the choices given, active and passive transport of solutes across a membrane typically differ because active transport always involves the utilization of cellular energy, whereas passive transport does not require cellular energy. The correct answer is B.
<h2>Inside the cones of pine tree</h2>
Explanation:
- The life cycle of a pine tree starts in the strobulus, the sexual conceptive structure in a completely adult pine tree. Strobulii is otherwise called the "pine cones." Male strobulii are in the lower some portion of the tree, while the female structures are in the upper part. The strobulli are viewed as unisexual structures since they have either male or female sexual organs. The male strobulli in a pine tree contains microsporocytes, grains that in the end form into dust. In the spring months, male strobulli discharge dust into the air, which is focused on the pine tree's female strobulli.
- A pine seed finds the right micro-climate, it will in the eventually sprout and a pine seedling begin to develop. Be that as it may, pine seeds are typically discharged in a torpid state, which is regularly broken by chilly stratification. Therefore, a pine seed won't grow until the accompanying spring when warm climate and some spring dampness are available. Since pine seeds are created in rich numbers, and just a small rate should be successful in building up new seedlings.
Answer:
Homeostasis is the process of maintaining a constant internal environment of the body with the help of certain mechanisms such as feedback loops.
Explanation:
Homeostasis refers to the maintenance of a relatively constant internal environment of the body. It includes maintaining several parameters such as acid-base balance, blood glucose level, body' temperature, etc. within the narrow range.
Homeostasis is mainly maintained with the help of negative feedback loops wherein the deviation of any parameter from the normal physiological range is counteracted and restored.
For example, the blood glucose level remains within the range of 70 and 110 milligrams of glucose per 100 milliliters of blood under normal physiological conditions. Any deviation from the range is restored with the help of pancreatic hormones insulin and glucagon.
