Answer:

B. The foam has tiny air pockets that slow the transfer of thermal

energy away from the water in the pipe

Explanation:

Air cannot conduct heat well and can be used as a good insulator. Poor heat conduction of the insulator. When it is cold outside, the temperature gradient will adapt to the environment. The temperature of the water in the pipe is relatively high. It loses heat to the environment. The foam layer prevents this form of heat exchange due to surrounding air pockets.

Answer:

B. The foam has tiny air pockets that slow the transfer of thermal

energy away from the water in the pipe

Explanation:

Air is a poor conductor thermal energy and can be used as good insulator. Insulators are poor conductors of heat.

When it is freezing outside, the temperature gradient will tend to adjust to the ambient one. The water in the pipe being at a higher temperature will tend to lose heat energy to the surrounding.

The layer of foam will prevent this form of heat exchange from happening because of the air pocket that is present around.

During the production of gametes, the chromosomes of a cell have condensed, and the chromatids of homologous chromosomes are cro
snow_tiger [21]

Answer:

The correct answer will be the cell is in prophase I of meiosis and will enter metaphase I next.

Explanation:

Meiosis is a type of cell division which is involved in the formation of haploid gametes.

During meiosis the division of the genetic material is markedly observed and based on this meiosis is divided into 4 phases: prophase, metaphase, anaphase and telophase.

During prophase: the chromatin structure of DNA starts condensing to form chromatids which attaches to homologous chromatids and are known as sister chromatids. These sister chromatids exchange their genetic material via a process called called recombination or crossing over which takes place during pachytene stage of prophase I. After crossing over it is proceeded by the next stage that is metaphase I in which chromosomes gets aligned at the center of the cell.

Thus, the cell is in prophase I of meiosis and will enter metaphase I next is the correct answer.
