Answer: Scientific observation
Explanation:
The reason for this is, Ben is observing the plants, coming up with questions.
Answer:
The scientific study of life, called <u>Biology</u><u>, </u>can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has <u> emergent properties</u> that result from interactions among component parts. Life's basic unit of <u>structure and function</u> is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, <u>nutrients and chemicals</u><u> </u>cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of <u>evolution </u>all of life is related by common descent. Life was diversified as <u>natural selection</u> had led to the gradual accumulation of adaptations that fit populations to the environment.
Explanation:
Emergent properties- Properties that is exhibited by a group of individuals as a result of interaction among them.
Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.
Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.
Answer:
Relationship between Yucca plant and Yucca moth is OBLIGATE MUTUALISM.
Explanation:
Obligate mutualism- The mutual relationship between two partners where both partners are benefited by each other and can not survive without each other.
In case of Yucca plant and Yucca moth,they cannot survive without each other.Yucca moth larvae feed on seeds of Yucca plant and Yucca plant have a single pollinator i;e, Yucca moth. Yucca moth collects pollen from anther and fly to another flower and transfer that pollen to other flowers stigma. In this way they transfer the pollen , usually they make a hole in the ovary to lay eggs and directly transfer pollen to the inside of the stigma.
After laying eggs they mark it with some special kind of pheromone which alerts other moths not to lay egg inside the same flower or lay some eggs not much. So that they can be protected inside the flower and can be developed well.
Fertilization which unites the sperm and egg.
What is a germ cell mutation?
A germline mutation, or germinal mutation, is any detectable variation within germ cells (cells that, when fully developed, become sperm and ovum). Mutations in these cells are the only mutations that can be passed on to offspring, when either a mutated sperm or oocyte come together to form a zygote.
What is affected in a germ cell mutation?
Somatic mutations differ from germ line mutations, which are inherited genetic alterations that occur in the germ cells (i.e., sperm and eggs). Somatic mutations are frequently caused by environmental factors, such as exposure to ultraviolet radiation or to certain chemicals.
