The action is Fixed Action Pattern.  It is a highly typecasted sequence of behaviors that, once begun, is usually carried to completion. It is triggered by a sign stimulus. The egg outside the nest is the stimulus.b <span>It is performed virtually the same by all regardless of environmental conditions. </span> Even if the egg is removed or slips away, she completes the behavior by returning an "imaginary" egg to the nest.

Nonvascular plants have a system that transports water and nutrients throughout the plant’s body
solniwko [45]

Answer:

False

Explanation:

Plants, based on whether they can conduct water and nutrients, are classified into vascular and non-vascular plants. Vascular plants also called TRACHEOPHYTES are plants that possess certain special tissues called vascular tissues used for conducting water and nutrients in a plant. These conducting tissues are xylem and phloem.

On the other hand, non-vascular plants do not possess vascular or conducting tissues, hence, they cannot transport water and nutrients throughout the plant. Hence, such plants are naturally found in moist areas e.g. mosses. Therefore, based on the question asked, the answer is FALSE.

How does the anaphase stage differ in the two phases of meiosis?
Ronch [10]

The answer is c. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells.


Meiosis is a cell division which results in the reduction of chromosome number by half (from diploid to haploid) in daughter cells. It consists of meiosis I and meiosis II. 

In anaphase I, the sister chromatids separate from each other to the opposite sides of the cells. In meiosis I there are 46 chromosomes in duplicates which are present as pairs of sister chromatids. When comes to separation, homologous chromosomes separates only, but not sister chromatids. Homologous chromosomes are present only in meiosis I.

 In anaphase II, since the cell is haploid, there are 23 chromosomes in duplicates, which are present as sister chromatids. So, in this phase, sister chromatids are those who separates.
