Answer:
The Earth can be divided into 5 main layers according to their physical properties: the lithosphere (most superficial layer of the Earth: rigid and cold), the asthenosphere (Second most superficial layer of the Earth: soft and ductile), the mesosphere or lower mantle ( Middle layer of the Earth: rigid and hot, able to flow gradually), the outer core (Second innermost layer of the Earth: liquid) and the inner core (innermost layer of the Earth: solid). The flow of heat inside the Earth will depend on the temperature and the characteristics of the material. The crust behaves like a solid and has relatively low temperatures. The mantle behaves like a fluid and since convection is much more efficient in this case, that is the main means of transport, even though the relatively high temperatures make it possible for energy to also be transported by means of radiation.
Explanation:
As you descend into the Earth's interior, the temperature, pressure, and density of the rocks gradually increase. The Earth can be divided into five main regions based on its physical properties (temperature and pressure) and according to its mechanical resistance: lithosphere the chemical composition of this layer is notably different, it also acts as a unit that shows a rigid behavior (not can be bent), mainly because it is cold and consequently resistant, asthenosphere located in the upper mantle (at a depth of about 660 km), there is a comparatively plastic soft layer, mesosphere (lower mantle) more rigid layer and it is because as the pressure increases, it counteracts the effects of the higher temperature and the resistance of the rocks increases gradually with depth. Despite their resistance, the rocks of the mesosphere are still very hot and are able to flow in a very gradual way, the outer core is a 2270 km thick liquid layer. The convective currents of iron in this area are those that generate the Earth's magnetic field and the inner core of the material is more resistant than the outer core (due to the enormous pressure to which it is subjected) and behaves like a solid. When penetrating the crust of the Earth a change in temperature is observed, in general it increases; this variation in temperature with depth is called a geothermal gradient. The heat flux on the Earth's surface is calculated as the product of the geothermal gradient and the thermal conductivity of the rocks, these two parameters being directly determined. The Earth is basically made up of three concentric layers: the innermost core has a composition of cast iron at a temperature of over 4,000 ºC; the mantle that is the intermediate layer formed by iron and magnesium silicates and its temperature varies from 4,000 ºC in its contact with the core to 800-1000 ºC of its outer surface that contacts the crust that is the most superficial layer and visible by man. This crust has a variable thickness of 5 to 35 km and is made up of aluminum and magnesium silicates, its temperature varying between 800-1000 ºC of contact with the mantle and 15-20 ºC of the surface that we know.

HELP!! I WILL MARK BRANLIEDT!! HERES A PIC ITS ABOUT NATURAL AND SELECTIVE BREEDING:)
Answer:
Natural Selection
- The process happens due to environmental activity
- It takes a relatively long period of time.
- Excessive warmer temperatures in a region have caused rabbits with longer fur to slowly disappear.
Selective Breeding
- Organisms do not choose to thrive but are selected because they are best adapted to the environment.
- A Labradoodle is created by scientists to be hypoallergenic but still look like a Labrador.
- It takes place over a relatively short period of time.
- Humans have a decision in the outcome of the offspring.
- Apples have gotten much larger over the last 30 years due to customer demand
Explanation:
From the above, I have been able to place them in their respective categories.
Natural selection simply has to do with nature. It is a process in nature that leads to the better adaptation of organisms to survive and reproduce in their environment. This type has to do with the natural environment. As nature plays out, it can take longer time and the environment can affect survival rate. Natural selection can lead to speciation.
Selective breeding can also be referred to as artificial selection. This process has to do with the input of man in developing new organisms that possess desirable characteristics and that can adapt to a specific environment. In other words, humans control and decide the outcome of the species that are reproduced. Such breeding process take relatively short time.

The diagram below shows a single animal cell with many of the cells organelles. Which structure contains the instructions for making a copy of the cell?
Answer:
The nucleus (On the image, it's the sphere in the middle)
It is the nucleus, which contains the instructions for making a copy of the cell.
What is a nucleus and its functions?It is a double-membrane-bound cell organelle found only in the eukaryotes, which comprises the genetic material. The prime function of the nucleus is to monitor a cell's reproduction and growth. It does not only store DNA, it also performs various essential cellular procedures.
The duplication of the DNA, that is, DNA replication takes place within the nucleus of the cell. It comprises the instructions for producing two identical copies of the cell, and each cell produced will get its own set of instructions. It is also the site for the process of transcription.
Thus, the nucleus is the structure that comprises the instructions for producing a copy of the cell.

The presence of freckles (F) is dominant to no freckles (f). Jake and his mom have
freckles, but his sister and Dad do not have freckles. Complete the Punnett square
that shows Jake's family.
Answer/Explanation:
(F) => dominant allele for presence of freckles
(f) => recessive allele for no freckles
Since Jake has freckles while his sister has no freckles, therefore:
Jake's dad must be => (ff) (this is the only instance the recessive trait of no freckle can manifest)
Jake's mum would be => (Ff)
Let's complete the Punnett square that shows Jake's family:
Dad------|---f---|---f---|
Mum--F-| Ff | Ff
----------f-| ff | ff
(ff) × (Ff) - Jake's Parent
Ff - Jake
ff - Jake's sister

While walking through a rainforest, a zoologist spots a colorful organism growing on a dead tree stump. Further examination reveals this organism is a
multicellular organism, possesses a nucleus, and has cell walls but no chloroplasts. The zoologist would most likely place this organism into which kingdom?
O A Plantae
OB. Decomposers
C. Prokaryotes
OD. Fungi
Answer:
D:fungi
Explanation:
The zoologist would most likely place this organism into Fungi kingdom. The correct option is D.
What is kingdom Fungi?Any member of the eukaryotic group of organisms, which also includes the more well-known mushrooms and microbes like yeast and mould, is referred to as a fungus.
Eukaryotic creatures known as fungi include yeasts, moulds, and mushrooms as well as other microbes.
These organisms fall under the category of fungus. The creatures that make up the Kingdom Fungi are pervasive and have a cell wall.
As a biologist notices a vibrant organism sprouting on a stump from a dead tree.
A closer look reveals that this organism is multicellular, contains a nucleus, cell walls, but no chloroplasts. He probably would have put this organism in the kingdom of fungi.
As prokaryotes and decomposers are not having the characters given by the zoologist and plant also possesses chloroplast, so it can come under Fungi Kingdom.
Thus, the correct option is D.

1. If your child had a child with a man with sickle cell disease, predict whether that child
would also have sickle cell disease. Explain the reasoning and describe the information
you used to make your prediction.
Answer:
Sickle cell disease (SCD) is a blood disorder that a child is born with. It's passed down through a parent’s genes. Children with SCD make an abnormal type of hemoglobin. This is the protein in red blood cells that carries oxygen to all parts of the body. With SCD, the body organs and tissues don’t get enough oxygen.
Explanation:
Healthy red blood cells with normal hemoglobin are round and move easily through blood vessels. When a child has SCD, the red blood cells are hard and sticky. They are shaped like the letter C (and like a farm tool called a sickle). These damaged red blood cells (sickle cells) clump together. They can’t move easily through the blood vessels. They get stuck in small blood vessels and block blood flow. This blockage can cause pain. It can also damage major organs.
Sickle cells die sooner than healthy cells. Normally the spleen helps filter infections out of the blood. But sickle cells get stuck in this filter and die. Having fewer healthy red blood cells causes anemia. The sickle cells can also damage the spleen. Without a healthy spleen, children are more at risk for serious infections.
There are several complex types of the sickle cell gene. Some don’t cause symptoms or severe problems, but others do. Talk to your child’s healthcare provider about the specific form of sickle cell your child has.
Most children with SCD will start showing symptoms during the first year, often around 5 months.
Answer:
IN my opinion I dont really thinkthe child would have ssickle cell because the mother or father dont have it, its only one part of its family have it but if the one part of its family sickle cell jeans is storng thn yes the child may get it .

Jason is swimming in his backyard pool and notices that sounds underwater are different than sounds above water. What best explains the difference in sounds?
Answer:
The different speed of the sound waves in water and in air.
Explanation:
Sound waves are defined as the mechanical waves that are resulted from the vibrations back and forth of the particles of the medium through which the sound is moving.
The speed of the sound is faster in water than in air. Sound travels much faster in water than in air. In air the speed of the sound waves is 343 meter per second while the speed of the sound waves in water is 1480 meters per second.
In the context, Jason who is swimming in his pool hears sound differently underwater and above the water because of the difference in the speed of the sound waves above the water and in water.
