Answer:
Explanation:
This is because ferns are vascular plants i.e they have vascular tissues which are xylem and phloems which help to conduct water and nutrients while mosses are non vascular plants.
2. Ferns sporophytes are differentiated into true leaves, stems and true roots while mosses lack true roots, stems and leaves.
Underground stems are modified part of plants that are derived from stem tissues which grow under the ground. Underground stems grow beneath the soil. Examples include Rhizomes, ginger, tubers e t.c.
Answer:
Yes because if you put salt in water soon after the water will be clear
The correct answer is signal transduction.
Signal transduction also called cell signaling refers to the conduction of molecular signals from the external of the cell to its internal. The signals perceived by the cells must be conducted efficiently into the cell to make sure an effective response. This step is stimulated by cell-surface receptors.
There are three phases in the procedure of communication or cell signaling, that is, reception, transduction, and response.
Answer:
Helicase
Explanation:
DNA replication is the process in which DNA makes copies of itself.
The process of DNA replication is supported by several enzymes.
The initial step of DNA replication is unwinding of double stranded DNA which is catalyzed by helicase enzyme. Helicase enzymes breaks the hydrogen bond between the DNA strands and prepare them for replication process.
Hence, the correct asnwer is "Helicase".
Answer:
Drive-reduction theory
Explanation:
Drive reduction theory is a motivation theory which is based on the principle that organisms are born with certain psychological needs and that they experiment a state of tension when these needs are not satisfied.
This state of tension pushes them to find a way to satisfy those needs, and when those needs are satisfied again, drive is reduced and the person returns to a state of homeostasis and relaxation.
According to this theory, <u>motivation happens when we experiment the state of tension and it's this motivation that drives us to satisfy our needs and be able to feel better. </u>
Dr. Williams is a psychologist who believes that motivation is produced when we feel an uncomfortable internal state that pushes us to find a way to feel better.
In this case, Dr. Williams thinks that our motivation originates from an uncomfortable state (state of tension) that pushes us to find a way to feel better (in order to reduce the drive and be back to homeostasis).
We can observe that Dr. Williams belief is very similar to the drive-reduction theory.
Note:
<u>a) Incentive theories of motivation state that people are motivated by incentives that are given to them (either internally or externally) when they do a expected behavior.</u>
<u />
<u>b) Maslow's hierarchy of needs states that our needs are based on a hierarchy in form of pyramid in which we first need to satisfy the needs at the bottom (physiological needs) to be able to proceed with the other needs that are higher on the hierarchy until we reach the self-fulfillment needs. </u>
<u />
<u>d) Instinct theory states that we are driven by instinct that we need to satisfy in order to experience balance and homeostasis. </u>
