Answer:

Why do you think the winter layers are darker than the summer layers in the ice core? The winter layers are darker than the summer layers because little snow falls in the winter. ... The summer layers are lighter because the snow that falls in the summer is cleaner; there are fewer particles caught in the snowfalls.

Explanation:

You can put it in your own words if you want. Hope this helps!

The winter layers are darker than the summer layers in the ice core because the summer snow is less tightly packed with particulate matter, therefore, it is brighter while the winter snow is more tightly packed due to the compaction and therefore it is darker.

Ice core may be defined as a structure of ice in a cylindrical shape which are plugged from the ice sheets or glaciers.

In winter, the snow that falls on the earth's surface is mixed with the more particulate matter due to compaction and hence it looks more darker as compared to summer snow.

Therefore, it is well described above.

Answer:

As shown in the pictures above, the ice is absorbing heat energy from the hand and the surroundings, which results in the melting of the ice- a process of change of state from solid to liquid. The hand feels cold .

Note: The question is incomplete as it is lacking some details.

Explanation:

Melting is a change of state process which involves the change from solid to the liquid state. Solids when they absorb heat, change to liquids at a temperature known as the melting point. This change of state occurs because the molecule of the substance acquires enough energy which to be able to overcome the intermolecular forces holding the ice crystals together, as a result, the molecules begin to melt.

In the picture,the melting of the ice held by the hand is because the ice absorbs heat from the hand as well as from the surroundings . As a result of this loss of heat from the hand, the hand feels cold after. The process of this heat transfer is by conduction whereby heat is conducted away from the hand in order to melt the ice which is contact with the hand.

Answer:

Heyaa!! My name is Pinky and i'm here to inform you that your answer is...

Explanation:

!!! an organism will adapt to survive an environment. For example if an environment is very cold the organism will develop a thicker coat to trap in heat. Another example is if it is an environment with many trees, an organism might develop claws to climb trees or a tail to assist with balance and climbing !!!

Have a nice dayy!!

Answer: Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal's genes are expressed, which ultimately affects the animal's phenotype. Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes are turned on and off, thereby influencing the way an organism develops and functions. include temperature, food, pollutants, population density, sound, light, and parasites. brainliest?

Get bigger graph paper as it says "The X-axis should be years and the Y-axis should be coal production." On the X-axis (Horizontal Line) write "Years" and on the Y-Axis (Vertical Line) write "Coal Production."

Now, your gonna start listing all the years on the X-Axis 1996 through 2011, And on the Y-Axis list all the coal productions 145 and all the numbers through 634. Make sure you have the regions, Appalachian, Interior and Western.

Answer:

decreases

Explanation:

Answer:

Yes

Explanation:

Natural selection was first postulated by Charles Darwin. It is the idea that organisms that are best adapted to their environment are able to survive and reproduce thereby transmitting their favorable characteristics to their offspring.

In our experiment, the insects that were able to survive were allowed to reproduce thereby transmitting their favorable characteristics to their offspring. This is a demonstration of natural selection.

Answer:

Herbivore, of course, I'm really sure that we all know exactly what a herbivore is, but as a refresher, a herbivore is like a vegetarian, they have a diet strictly based on plants. Carnivore's eat meat, not vegies, and an omnivore eats both, most humans are labeled as omnivores, except vegetarians. So your answer is Secondary Consume. This is because they only receive 10% in vegies, Primary Consume get 90%, Herbivores are Primary Consume's.

Answer:

1. Fossil record  

2. Comparative anatomy

3. Embryology

4. Biogeography  

Explanation:

Evolution is descent with modification. The organic evolution theory states that present complex life forms have evolved from the earlier (simpler) forms of life over time. Some of the most important pieces of evidence in support of the theory of organic evolution are:  

1. Fossil record: fossils are dead remains of past living organisms preserved in the rocks of the remote past. These fossils demonstrate the existence of past living organisms that are related to present-day organisms.  

2. Comparative anatomy refers to the study of similarities in the anatomy of different species, which provides direct evidence for identifying common ancestry between related species.

3. Embryology: the more recent the ancestor is that two species share, the greatest similarities in embryo structures and the more closely related the species are. In this regard, it is important to highlight that often homologous organs/structures (i.e., organs/structures descended from a common ancestor) can be observed only in embryos.

4. Biogeography refers to the spatial distribution of organisms and species. Species distribution reflects the evolutionary process when it is combined with geological change. For example, taxa that had already appeared before ​the separation of the continents are often distributed worldwide.

Answer:

The tires lose air pressure in the winter because it contracts. If you have 35 lbs in the summer, with 85 degrees, when it gets cold, down to -10, your air pressure can get down to about 25 lbs. So before it gets bitter cold, inflate your tires up a little. You don’t want to be putting air in your tires once it is freezing out. Sometimes the schrader valve doesn’t seat properly because of frost and the rubber seal is hard. I have had several tires go flat on me because of this.

The question is incomplete, the complete question is;

A ray of light travelling in medium 1 strikes and travels into another transparent medium, medium 2. If the speed of light is greater in medium 1, the ray will ............ *

refract away from the normal.

undergo total internal reflection.

refract towards the normal.

have an angle of incidence smaller than the angle of refraction.​

Answer:

refract towards the normal.

Explanation:

Refraction refers to the bending of light waves or change in the direction of light waves as a result of change in the speed of light at the boundary between two media.

Whether the rays bend towards or away from the normal depends on the density of the both media. When light travels from medium 1 to medium 2 and medium 1 is less dense than medium 2(shown by a greater speed of light in medium 1 than medium 2) then the ray of light refract towards the normal and vice versa.
