Answer:
A) hybridization; morphospecies
Explanation:
The biological species concept is the concept which can define a species as an individual of a large population which can interbreed and produce an offspring in a population. The concept was given by Ernst Mayr.
Morphospecies refers to the species which can be characterised by the differences in their morphological features like in the Oak, willows and the dandelions.
The biological species concept is not valid or complicated in the case of the morphospecies like in the Oak, willows and the dandelions as the individuals of these three population can exchange their genes through the process of hybridization.
Thus, Option-A is the correct answer.
Answer:
A
Explanation:
We do not gain the mass of the food we eat. Therefore, B is wrong. Our cells do not grow in size, they only grow in number. Therefore, C is wrong. Although the puppy's body does, in a way, stretch out, A is a better option. Therefore, D is likely to be wrong.
The added energy is need to break hydrogen bonds between water
Answer:
The electron has a negative charge. The electron is smaller than the other particles and can be found outside of the nucleus, which is another name for the center of the atom. In the center, there are protons and neutrons. The neutron have no charge but weigh a lot compared to the electron. The proton has a positive charge. In order to get the atomic mass, add the number of protons and neutrons together.
Explanation:
Marble is a metamorphic rock.
Most of marble forms at Earth’s convergent plate boundaries where Earth’s crust is exposed to metamorphism (process in which sediments will pile over top each other on either sedimentary or igneous rock. The rocks will be exposed to extreme During metamorphism, marble can be exposed to hot magma body that will recrystallize the calcite (CaCO3) and its texture will change over time. Minerals in marble can also change. During this process, marble will eventually change to limestone because calcite contains other minerals such as micas, quartz, pyrite, iron oxides, and graphite.
