Can Someone Pls Help Me With This 2 Questions!!

Answers

Answer 1

Answer:

water contracts and ice sinks

Answer 2

Answer:

For #2, water expands when it freezes, therefore it floats!

Explanation:

Water first condenses when it freezes until it reaches about 4 degrees Celsius, where it then slowly expands by about 9%. It also floats! You can observe this yourself by placing ice into a glass full of water.

Ice floats because it is less dense than the water below.

Study the pedigree chart. ( picture above)

Which of these can be determined about the trait based on this chart?

○ The trait is recessive. the parents of A were both carriers

○ The trait is recessive. The parents of A were both affected

○ The trait is dominant The parents of te were both affected.

○The trait is dominant The parts of A were both carriers​

Answers

Answer: The trait is recessive. the parents of A were both carriers

Explanation: The correct answer should be the trait is recessive.

Since we can only see A mothers tree and she is not affected by the trait she is a carrier.

Unfortuately, the tree does not show her father's side of the tree so we can only "assume" based on the options that he also is a carrier of the trait.

So answer it will be "The trait is recessive. the parents of A were both carriers"

I am able to fill a glass of water to the top and it does not overflow…which property of water allows this to happen

Answers

Answer: surface tension

Explanation:

Answer:

When we fill the glass with water, we notice right away that it can go over the brim of the glass without spilling. This is because of surface tension. Surface tension holds the water together and acts against what would normally cause the water to fall – gravity – because each molecule of water is attracted to the other water molecules around it.

Explanation:

extra facts Water molecules are attracted to each other and is why you can fill a glass and as it gets to the top it will stay together to a certain point. However that stick together ability is pretty mild so when gravitational forces take effect the bonds are broken and it flows down the sides of the glass. Unfortunately, the attraction between the water molecules is only so strong. As we add coins, the amount of water spilling over the edges is getting larger and larger until the water just can’t take it anymore! Gravity is pulling on too many of the molecules for their attraction to keep them up, and the water spills down the side of the glass.What to Do. Place the glass on the saucer and fill the glass of water all the way to the brim. You’ll notice that the water hangs slightly over the top of the glass but doesn’t spill out just yet. Now, add the coins one at a time to the glass of water, dropping them in rim-first (not face down).

I looked up the definition of transmitted and it fits better

DNA is transcribed to mRNA, which then attaches to a ribosome where it is translated into a protein. The correct answer is option C.

What is the role of mRNA ?

mRNA is the code of DNA that carries the information of coding proteins from the nucleus to the cytoplasm.

DNA is transcribed into mRNA where it is transcribed intro message to which kind of protein is about to be formed. A triplet forms one amino acid and this process is taking place in the ribosome.

The chain of amino acids forming a protein is released in the cytoplasm and the proteins is then assigned a particular position where so ever is them needed mostly in the cytoplasm.

Therefore, DNA is transcribed to mRNA, which then attaches to a ribosome where it is translated into a protein. The activity takes place in the ribosome.

Joe, age 14, recently fractured his forearm midway between his wrist & elbow. Should his physician be concerned about his epiphyseal plate being affected and causing bone growth to stop?

Answers

Joe's doctor must be concerned that his bone growth will be hampered by damage to the epiphyseal plate.

We can arrive at this answer because:

The epiphyseal plate is a set of cartilage present at the end of long bones, such as the bones present in the forearm.The epiphyseal plate is responsible for the longitudinal and lateral growth of the bone.This growth occurs during childhood and adolescence, for this reason, it is essential to maintain the good integrity of this plaque during this time of life.

In the case of Joa, who is still a teenager, a fractured forearm can damage his epiphyseal plate and affect his body's bone growth, so his doctor should be concerned about this.

It is important to note that during adult life, the epiphyseal plate is replaced by an epiphyseal line.

The hypotheses about the dwarf planet Pluto can be divided into the following:

Non-falsifiable

Pluto has an unpleasant climate.Pluto's landscape is dull and boring compared to other dwarf planets in its vicinity.  

Falsifiable

Pluto's surface is made mostly of frozen nitrogen..Pluto's orbit is slowing down due to tidal friction.What is Falsifiable and Non-falsifiable hypotheses?

Falsifiability is the capability for some proposition, statement, theory or hypothesis to be confirmed wrong. That capacity exists as an important component of the scientific approach and hypothesis testing. In a scientific context, falsifiability exists sometimes regarded synonymous with testability.

The falsifiable hypothesis can be denied by tests done with the most delinquent technology. The non-falsifiable hypotheses on the other hand can't refuted as tests have confirmed them to be true.

Hence,

The hypotheses about the dwarf planet Pluto can be divided into the following:

Non-falsifiable

Pluto has an unpleasant climate.Pluto's landscape is dull and boring compared to other dwarf planets in its vicinity.  

Falsifiable

what is the effect of water temperature on corals from inshore and offshore reefs?

Answers

Answer:

When the water gets too warm, the algae can no longer live inside corals, so they leave. The corals then turn from green to white, called coral bleaching. Climate change has been causing the Earth's air and oceans to get warmer. With warmer oceans, coral bleaching is becoming more widespread.

Explanation:

When the water temperature rises too high, algae can no longer live inside corals and leave. Coral bleaching occurs when the corals turn from green to white.

What are coral reefs?

A coral reef is an underwater ecosystem characterized by corals that build reefs. Reefs are made up of coral polyp territories hosted along by calcium carbonate.

The vast bulk of coral reefs are mainly composed of stony corals, which have polyps that coalesce together.

Coral reefs grow in shallow water with temperatures ranging from 68° F to 97° F. The Indo-West Pacific biogeographic region contains more than 90% of the world's coral reefs.

When the temperature of the water rises too high, algae can no longer live inside corals and must leave. Coral bleaching occurs when corals alter color from green to white.

The Earth's air and oceans are becoming warmer as a result of climate change. Coral bleaching is becoming more common as the oceans warm.

Thus, this is the effect of water temperature on corals from inshore and offshore reefs.
