Answer:

Experimental Procedure:

Mix 10 drops of tincture of iodine with 30 drops of water to make an iodine solution. Put a cracker on a plate, and test it for starch using a drop of the iodine solution. Chew a second cracker for 60 seconds until it is completely mixed with saliva.

Mountain Pine Beetle.

They only attack in Douglas Fir Trees.

Answer:

Environmental causes such as habitat fragmentation, climate change, natural disasters, human overexploitation, and pollution, or evolutionary changes in its members (genetic inbreeding, poor reproduction, decline in population numbers).

Answer:

Ribosomes create the thermoreceptors of the body. Another example of a homeostatic condition maintained by proteins is blood-glucose levels. When our blood-sugar levels get too high, specialized cells in the body release a protein hormone called insulin.

Answer: Ribosomes play a key role in homeostasis. Without ribosomes, a cell would not make proteins. A cell with no ribosome would simply not function. With no protein reproduction to maintain the cell wall there would be no barrier to keep invasive bodies from damaging the inner workings of the cell, there would be no way to produce the needed proteins for rebuilding and maintaining the cell.

Vertebrae are the 33 individual bones that interlock with each other to form the spinal column.

Explanation:

The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

The selection that acts over evolutionary time to preserve traits that increase an individual's ability to mate is known as se_xual selection.

The expression 'se_xual selection' makes reference to the type of evolutionary constraint on the individual's ability to mate.

Se_xual selection is fundamental to increase the genetic variation and thus enhance adaptive chances.

Se_xual selection can be considered a special type of natural selection that acts at an individual level.

Photosynthesis ceases when leaves wilt, mainly because stomata close, preventing CO2 from entering the leaf.

Photosynthesis is a series of chemical reactions by which plants can produce simple carbohydrates in presence of light.

Photosynthesis requires carbon dioxide and light to produce glucose and release oxygen.

In plants, the interchange of carbon dioxide and oxygen during photosynthesis occurs in specialized structures called stomata.

Answer:

Friction

Explanation:

When an object comes into contact with another object, friction is created, some objects have lower or higher friction when they meet each other, tires and the road for instance. Wheels are designed to lower friction, just as an ice skate is made to glide across the ice.

The code contains 64 codons. The genetic code is almost universal.All living organisms store their genetic informations using the same molecules which are DNA and RNA

Explanation:

Answer:

The answer would-be producers. The fact that there are primary consumers today, you would know that producers make up the bigger population. If it were smaller, the primary consumers would have eaten them all up and eventually would die out because they would have no more food source. This would be bad for all higher-level consumers.

The most likely cause potential flooding in the area will be saturation of the ground with water.

This is defined as a situation in which an overflow of water submerges land that is usually dry.

When the ground is already saturated with water, a forested area receiving a lot of rain in a short amount of time will lead to flooding.

Deforestation increases the risk of floods in an area tree roots improve soil water retention.

When deforestation takes place, the top layer of soil can be dislodged – this is also known as soil erosion.

When the top layer of soil is unstable, it is unable to retain any of the water that falls on it, resulting in increased surface run-off, which, in turn, increases the risk of flooding.

Thus, option "D" is correct.

The Miller Urey experiment refer to a form of chemical experiment that simulated the conditions present on the early Earth and tested the chemical origin of life using those conditions . The experiment performed at the time supported Alexander Oparin's and J. B. S. Haldane's hypothesis that putative conditions on the primitive Earth is important for chemical reactions to produce more complex organic compounds from simpler inorganic precursors.

The first was the “primordial soup” which was a conclusion that when Earth was young, the oceans were filled with simple chemicals important for life and this assemble into living cells.

We are changing the content in the formula to the content in cell D8.

The question refers to the cells that we find in computer data processing programs that include a spreadsheet as the main tool.

In these programs we can edit each cell with different information and include formulas so that the cell data depends on others.

According to the situation presented, the first action we performed was to establish a formula in cell C8 to obtain the result of an operation in that cell. Later, we change it to cell D8, then we will see the result of that same operation in cell D8.
