Answer and Explanation:
In homeostatic control processes any deviation from the norm sets into motion the appropriate corrective mechanisms which restore the norm. This rectification occurs through negative feedback. When you go outside wearing a sweater on a hot day, the body sends messages to the CNS and the following occurs:
- The superficial blood vessels vasodilate so that more blood flows near the surface. This encourages heat loss.
- Sweating and panting. Sweat secreted by the sweat glands evaporate from the surface of the body as it absorbs latent heat.
- The metabolic rate falls so that the body generates less heat. You also become less active
- Behavioural response by seeking cooler areas, cold drinks or removal of the sweater.

The answer is c. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.
Meiosis is a cell division which results in the reduction of chromosome number by half (from diploid to haploid) in daughter cells. It consists of meiosis I and meiosis II.
In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicates which are present as pairs of sister chromatids. When comes to separation, homologous chromosomes separates only, but not sister chromatids. Homologous chromosomes are present only in meiosis I.
In anaphase II, since the cell is haploid, there are 23 chromosomes in duplicates, which are present as sister chromatids. So, in this phase, sister chromatids are those who separates.
True rib : the first seven ribs attach to the sternum (the breast bone) in the front and are known as true ribs (or sternal ribs)
False ribs: the lower five ribs do not directly connect to the sternum and are known as false ribs
Floating ribs :The floating ribs are less stable and risk breaking because they have only one attachment
Dorsally to the vertebrae and have very thin bone tissue locked in muscle as they extend
Laterally.
The best answer is D.
A carbon sink is anything that absorbs more carbon than it produces or releases.
The main carbon sinks found in nature are plants, the ocean and soil. Plants such as trees capture carbon dioxide from the atmosphere and use it in photosynthesis. Part of this carbon is transferred to soil as the trees and other plants die and decompose.
Due to the effectiveness of trees and other plants as carbon sinks, the Kyoto protocol proposed that emission reduction can be achieved through absorption of carbon dioxide by these plants.
