Lamarck's theory of inheritance of acquired characteristics states that the physical changes in the body parts of an organism are inherited to their off spring from generation to generation. During his study of physical appearance ( phenotype) of organism Lamarck said that the characters adopted according to the changes in environment by organism as a physical change in body are inheritable e.g giraffes long neck due to shortage of food the giraffes in order to reach to higher trees had to make their neck long so their neck length was increased and they had long necks so the new offspring when burn had long necks so on this basis he said that the physical changes are inherited. Giraffes with long neck had more chances of survival in the environment.
<h3>1.The correct answer is:</h3><h3>b.earthquake</h3><h3>Explanation:</h3>
An earthquake is created by tectonic plates becoming united and placing a force on the ground. The tension grows so great that rocks give way by cutting and driving along fault extensions.
<h3>2.The correct answer is:</h3><h3>These mountains likely formed from compression.</h3><h3>Explanation:</h3>
Mountain embodiment relates to the geological methods that hold the extension of mountains. Various aerial enduring continental margins various reasonable share the identical mechanism of uplift. where folding is created by horizontal compression operating on a thin to the thick crust development zone .
<h3>3.The correct answer is:</h3><h3>formed when crust pulled apart
</h3><h3>
formed at a divergent boundary
</h3><h3>
formed when tectonic plates separated </h3><h3>Explanation:</h3>
The Rift Valley was created by powerful subterranean oppression that ripped aside the earth's crust. These powers prompted huge parts of the crust to decline between parallel lapse lines and drive up the molten stone in volcanic explosions.
<h3>4.The correct answer is:</h3><h3>expanding gases</h3><h3>Explanation:</h3>
As they rise, gas particles in the magma arise out of suspension and make bubbles and as the bubbles rise they expand. Eventually, the pressure from these bubbles is greater than the enclosing solid rock and this neighboring rock fissures, letting the magma to get to surface.
The majority of the lipids contained in our diet and retained in our bodies are triglycerides, esters made of one glycerol (an alcohol) molecule and three fatty acid molecules (carboxylic acids).
The ester of glycerol and three fatty acids is known as a triglyceride. In humans, other vertebrates, and vegetable fat, triglycerides make up the majority of the body fat. Obesity and the metabolic syndrome, a group of diseases marked by excess body fat around the waist, high blood pressure, high triglycerides, high blood sugar, and abnormal cholesterol levels, are two conditions that frequently accompany high triglycerides and increase the risk of heart disease and stroke. A blood supply blockage to your heart or brain could result from extremely high triglyceride levels. Chest pain may be one of the signs of a heart that is receiving less blood. Numbness, vertigo, disorientation, blurred vision, or a severe headache all be signs of a reduced blood supply to your brain. A particular health risk is quite curable.
