Answer:
The correct answer is " two cardiac muscle cells are connected by gap junctions".
Explanation:
Intercalated discs are microscopic features seen in the microscope as cardiac fibers, found between the myocardial cells of the heart. These features correspond of two cardiac muscle cells connected by gap junctions. The intercalated discs allow the interconnection of multiple cardiac cell muscles to work simultaneously as a single functional organ or syncytium.
Answer:
Blue offspring only
Explanation:
If A blue budgie is crossed with a white budgie.
i.e yyBB or yyBb × yybb
let use yyBb for blue budgie,so we have; yB, yb, yB, yb representing the columns on the horizontal rows of the punnet square.
on the other hand, in white budgie yybb, we will have yb, yb, yb, yb representing the rows on the vertical column of the punnet square.
if a dihybrid cross occurs among these representative, all progeny in the punnet square will be yyBb, showing that they are all Blue offspring only.
False
Facts are simple observations of the world, and they do not change over time until unless the theory was changed due to different research . Theories are hypotheses about what these facts mean, or how they should be understood, and they could change over time..
Answer:
<h2>1. larvae</h2><h2>2. metamorphosis</h2><h2>3. juveniles</h2>
Explanation:
- All organisms that may be unicellular or multicellular organisms are formed or developed from a single cell.
- In the case of multicellular organisms, a single cell that is called zygote divides and changed into different stages and finally forms an individual.
- In certain organisms the young animals do not resemble their parents or adults and are called larva such as Caterpillar that is the larval stage of the butterfly.
- Such type of the mechanisms or process by which larval stage changes into adult forms is known as metamorphosis.
- When organisms look like their parents but are sexually immature then such types of organisms are called juvenile organisms.
