The organisms is <u>D. Methanogens </u>

<h2>Explanation:</h2>

Prokaryotes are the organism which is made up of a cell that does not contain a membrane enclosed nucleus. They have a structure called as nucleiod which looks like a thread in appearance. The eukaryotes are the organism which has membrane bound nucleus.

Among the given list of organism in the options, Methanogens are microorganisms that produce methane as a metabolic result in hypoxic conditions. They are prokaryotic and have a place with the space of archaea.

Apart from this, amoeba, grass and cockroach have membrane bound nucleus.

Answer: d. mothering style affecting the developing brain

Explanation:

Epigenetics is the study of features or "phenotypes" which do not involve changes in the DNA sequence. Epigenetics is about how genes are expressed and used instead of the DNA sequence of the genes themselves.

The behaviour of a person's genes depends not only on the DNA sequence of the genes, but also on so-called epigenetic factors. Effects on genes from the external environment can affect disease, and some of these effects can be inherited in humans.

So, Mothering style which affects the brain development is an exampe of epigenetics which do not show any genetic feature.

A. Air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.

Explanation:

The most likely observation the student will record is that the air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.

This phenomenon between the differences in land and water temperature causes land sea breeze to occur.

Water has a very high specific heat capacity.
This implies it takes more heat to cause a monumental increase in its temperature.
It is expected that the student will observe that the air over the lake body will reach its highest temperature later in the day. It would have gotten heated with time.

A body such as water in a lake with a high specific heat capacity stays warm for a longer period of time compared to other substances.

Metals do not have high specific heat capacity and would not stay warm for long. They quickly lose heat.
