Answer:
Option B, Observation 2
Explanation:
The four main observation of Darwin’s areas follows –
Observation 1 – Variation occurs in the species with time leading to evolution. Offspring of two parents vary distinctly in traits such as height, color, weight etc. These variations are also affected by the surrounding environment
Observation 2-
Based on observation 1, Darwin concluded that offspring inherit traits from their parents. These traits improve the odds of survival and only genetic traits will be passed. Traits developed in an individual due to environment will not be passed on.
Observation 3 –
Offspring compete among themselves to survive.
Observation 4
The fittest among the competing species for survival will survive and pass on its traits to the next generation.
Since here the Pigeon breeders want to exemplify the looks (a genetic trait) of parents to their offspring, observation 2 applies here
Hence, observation b is correct
The movement of nutrients into the vascular stele requires energy, unlike the movement of water that does not require energy. This energy is provided by the phloem. Sugars are produced in the leafs, as part of the photosynthesis process, so whenever a new root is growing, or a fruit needs to grow, the phloem gets in action. With the help of the water the sugars get in the phloem, which can most simply be seen as an elevator inside the plant, that is moving nutrients up and down, on the places in which they are most needed.
Answer: Well for one, Differentiate is when a cell matures and is used in a specific function. Meristem is a cell which never differeates and constantly divides so it is a mitotic cell. Elongation is the plant growing length wise therefore the meristem elongates the plant. Vascular cambium is the cambium which starts out in vascular bundles of the plant and then grows to form a ring inside the stem of plants that live for more than year- it causes and increase in thickness of the stem and branches.
