In the life cycle of a Spider, there are no larvae, pupae, or nymphs stage.
Explain the life cycle of a spider.The first stage, egg
When a female has mated, she stores her spermatophores until she is ready to lay her eggs. The number of eggs is between a few and tens of thousands.
The second stage, egg sacs
The progeny develops in the egg sac, which was designed to shield the eggs from the weather and from predators like birds and ants.
The third stage, spiderlings
The young spiders that resemble their parents the most are called spiderlings.
The fourth stage, adults
The majority of spider species mature in five to ten molts. The spiderlings are prepared to reproduce and restart the life cycle once they reach adulthood.

In vesicular transport, __________ transport materials into and out of the cell using _______.
Endocytosis and exocytosis transport materials into and out of the cell using vesicles.
Endocytosis is called the process by which cells incorporate into them molecules, large or small, which are covered by the formation of a vesicle that detaches into the cell, forming phagocytic vesicles.In exocytosis, the proteins or molecules produced in the endoplasmic reticulum are wrapped in a vesicle towards the Golgi apparatus, where they are released to be used by other cells or by the body in different processes.Therefore, we can conclude that exocytosis and endocytosis are the biological processes responsible for the transport of particles and substances into and out of the cell.

What changes during a controlled experiment? A. A variable B. The results C. The conclusion D. The hypothesis
Answer:
Option B
Explanation:
The answer is option B or "the results." Wouldn't be option A because a variable depending on the type is tested during a experiment if you change the variable you have a whole other experiment going on, it wouldn't be option D because your hypothesis is a logically guess at the beginning of a experiment of what you think is going to happen and it doesn't change. It wouldn't be option C because the conclusion is at the end of the experiment after you finished testing, recorded the results, and found out if your hypothesis is correct meaning it doesn't change, leaving option B as your answer.
Hope this helps.

What would you need to do to your model to make it look like real DNA? Describe how you would make it 3-D.
Simply draw a realistic drawing of the DNA, try to add it as much details as possible. You can also use furnitures or recycling items around you if you're making a model, for example...
you could use fuzzballs or marbles for the outside, and perhaps thin construction tubes for the DNA strands?
Maybe twist paper against a pencil for the outside, with a pencil being used as the DNA strands? I sincerely hope this helped!

What direction will solutes move if a protein pump is functioning properly?
Answer:
Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane.
