Construction workers attach ropes and pulleys to wooden timbers on an old bridge.
They use the rope and pulley system like the one in the diagram below to move the
timbers away from each other, in order to dismantle the bridge.
Answer:
It is a safe and efficient method.
Explanation:
This method of dismantle the bridge is also a good one but there are some other methods also that are used instead of rope and pulley system such as destroy the bridge by using bombs at the base of pillars and cutting of each part in order to dismantle the bridge. This rope and pulley system is also an efficient way to dismantle the bridge so that's why the engineers used this method instead of other methods due to its safe method.
write four observable differences between rat and toad
Answer:Frog or toad: how to tell the difference
Skin
If there was ever a tell-tale sign to indicate which amphibian you are looking at, it’s the texture of their skin. Toads are warty-looking, covered in little lumps and bumps, while frogs are sleek and smooth. Toads also virtually always have dry skin, whereas frogs look wet even when they are out of the water.
Location
If you’ve spotted an amphibian making its way along a pavement or ambling through some grass, chances are it’s a toad. Toads cope much better with dry conditions than frogs, as their skin is more waterproof. Frogs lose moisture a lot more easily, and so are rarely seen too far away from water, which explains why they always look moist.
Legs
Frogs have long legs, longer than their head and body, which are made for hopping. Toads, on the other hand, have much shorter legs and prefer to crawl around rather than hop.
Explanation:
Answer:
1. color.
2. texture and or roughness. the rat will be smooth and the toad will feel rough against the skin.
3. growth/ size. rats can grow to be huge and toads tend to stay kind of small.
4. rat has a tail and toad does not.

the chemicals in cigarette smokers are known to cause cancer propose a series of steps that could lead to the development of lung cancer in a smoker
Answer:
Cell deterioration
Explanation:
Once the cells first come in contact, they immediately create a cell shield that is composed of weaker cells, while the rest continue their work, the problem with this, is that their is a lack of cells to do work and the weaker cells are slowly dying and creating holes for the harmful chemicals to enter, as the cells deteriorate they clot together and create a lump in a final attempt, and it ends up creating deadly weight in the lungs.

A mutation that could be inherited by offspring would result from-?
Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.
Explanation:
A mutation that could be inherited by offspring would leads from a base substitution in gametes during meiosis. The correct option is D.
What is mutation?Any alteration to a cell's DNA sequence. Alterations in cell division can result in specific mutations.
As can exposure to environmental DNA-damaging substances. Mutations may be negative, positive, or ineffective.
Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
A base substitution in gametes during meiosis would result in a mutation that might be passed on to progeny.
Thus, the correct option is D.

What are the features of boulder rocks?A boulder is defined as any rock larger than 16” in diameter. They are available in two basic shapes: round and angular. Round boulders have smooth edges and curves.
Moreover, a boulder is a rock fragment with size greater than 25.6 centimetres (10.1 in) in diameter. Smaller pieces are called cobbles and pebbles.

1. Explain the pathway of Endosymbiosis, and explain the job of all the organelles involved.
Answer:
All living things are made up of cells. Even though there are many millions of life forms on earth, all of them are made up of only two basic types of cell: prokaryotes and eukaryotes.Cells contain DNA. Prokaryotes (pro-carry-oats) are small and simple and have rings of circular DNA floating free inside the cell. Eukaryotes (you-carry-oats) are large and more complex.

In order for two new cells to be created during mitosis, each cell must receive an identical copy of DNA. In order to accomplish this task efficiently prior to mitosis, a cell will condense DNA into
Answer:
chromosomes
Explanation:
A cell must condense DNA into chromosomes before it can divide mitotically to form two new cells with identical copies of DNA.
The condensation of the DNA happens at the initial phase of the mitosis - the prophase - during which the DNA thickens and condenses to form chromosomes.
These chromosomes then align at the cell's plate during metaphase and they become separated into sister chromatids through the pulling of the spindle fiber at anaphase. Separated chromatids of the same chromosome are then transported to the opposite ends of the cell where they decondense before cytokinesis takes place.
