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.

Hence, the correct option is d.

an igneous rock forms quickly. which characteristics could the rock have? small sand grains. Large mineral crystals. smooth, sha
Shalnov [3]

Igneous rocks are formed by hot melted magma coming from the Earth's core that crystalizes when gets in contact with air. They can be either intrusive or extrusive. B) <em>Large mineral crystals.</em>

<h3>What is the igneous rock?</h3>

These rocks come straight from the interior of the Earth.

A liquid mass of silicate composition comes from the Earth's core. This melted mass comes at an extremely high temperature.

Magma begins to cool and solidify during its ascent to the Earth's surface. It solidifies and crystallizes into igneous rock following the magnetic field orientation.

Thre are two types of igneous rocks

• plutonic rocks ⇒ in areas close to the terrestrial crust ⇒ intrusive

• volcanic rocks ⇒ on the surface ⇒ extrusive

According to this description, the correct option is B. <em>Large mineral </em><em>crystals</em><em>.</em>

How do trees act as carbon sinks?
Romashka [77]


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.
