Explanation:
In Earth’s history before the Industrial Revolution, Earth’s climate changed due to natural causes not related to human activity. Most often, global climate has changed because of variations in sunlight. Tiny wobbles in Earth’s orbit altered when and where sunlight falls on Earth’s surface. Variations in the Sun itself have alternately increased and decreased the amount of solar energy reaching Earth. Volcanic eruptions have generated particles that reflect sunlight, brightening the planet and cooling the climate. Volcanic activity has also, in the deep past, increased greenhouse gases over millions of years, contributing to episodes of global warming
Answer:
D) Cartilaginous synchondrosis
Explanation:
Cartilaginous synchondrosis is a joint in which the bones are joined to the hyaline cartilage or the hyaline cartilage joins the bones.
The synchondrosis is of two types- the temporary and permanent synchondrosis in which the temporary synchondrosis represents the growth plate or epiphyseal plate of the hyaline cartilage which connects the shaft of the bones to the end of the bone.
The thickness of the epiphyseal plate in the children does not change as the bone lengthens.
Thus, D) Cartilaginous synchondrosis is the correct answer.
Mitochondria = known as the powerhouses of the cell.
They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.
The offspring will inherit one allele from each parent.
<h3><u>Explanation</u>:</h3>
The genetic crossing experiments lead to the formation of different hybrids which has several characters unlike their parents. Here the parents are homozygous.
One of the parent is homozygous yellow with respect to seed colour. So genetic combination of the parent will be YY.
The other parent is homozygous green with respect to seed color. So genetic combination of the parent will be yy.
Now as they are crossed the offsprings will have genetic combination of Yy.
This is seen that the offsprings carry one allele from both the parents.
