Some years ago, before crude oil prices became an economic concern and an international political issue, a biologist proposed a curious-sounding plan. He suggested that a portion of our crude oil supplies be converted directly into edible food, instead of distilling it to gasoline for the typical farming methods for raising food.
Before you become nauseated at the idea, you should know that this conversion has been done on a trial basis. Making edible, non-toxic food from petroleum is feasible. Also, considering that the components of fossil fuels were once ordinary plants and animals in an ordinary food chain, maybe there is some logic in his plan. What does crude oil amount to, anyway, but dinosaur fat? (No, really it is primarily formed from microscopic organisms.)
It might be the right time to form a new corporation and market a new product. What shall we call it…”DinoSnack,” maybe? With interest in dinosaurs as high as it is, how can we go wrong?
Your task is to evaluate this suggestion, allowing for both pro and con, the positive and the negative aspects of it. Surely there will be economic and political considerations, but concentrate especially on the biological, ecological factors.

In Andalusian chickens, feather color is inherited by incomplete dominance. If one parent with black feather (BB) is crossed with a white feathered parent (WW), all the offspring will have blue feathers (BW).
What is the percent chance of producing blue-feathered offspring when crossing a blue-feathered hen with a white-feathered rooster?
Question 1 options:
25%
50%
100%
75%
Crossing a blue-feathered hen with a white-feathered rooster has a 75% probability of producing blue-feathered offspring. The correct response is option (4).
Define incomplete dominance.In a genetic condition known as incomplete dominance, heterozygous people express both alleles. A person who possesses two distinct alleles for a specific gene locus is said to be heterozygous.
Complete dominance, on the other hand, happens when the dominant allele completely obscures the recessive allele.
As a result of having distinct alleles, blue feathered chickens are NOT purebred. BW AND WW both include Ws, they both have 3 Ws which equal 75% since each letter represents 25%

Answer:
1) Weathering, Erosion, Disposition
2) Physical weathering is the breakdown of large rocks into fragments by physical forces; the chemical composition of the rock is not changed. Chemical weathering is the breakdown of rock by chemical reactions; the chemical composition is changed.
3) The four forces of erosion are water, wind, gravity, and glaciers.
4) Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.
--------------------------------------------------------------------------------------------------------
Abrasion: Abrasion is the breaking down and wearing away of rock material by the mechanical action of another rock. Three agents of physical weathering that cause abrasion are moving water, wind, and gravity. Also, rocks suspended in thence of a glacier can cause abrasion of other rocks on Earth's surface. This would be a prime example of physical weathering, or mechanical weathering.
----------------------------------------------------------------------------------------------------------
Acid Precipitation: Acid rain causes less erosion than normal rainwater does. Rainwater can break down rocks by dissolving minerals in the rocks. Acid rain is rainwater that is more acidic than normal rainwater. Acid rain can also dissolve the minerals in rocks faster than normal rainwater can. This is chemical weathering.
--------------------------------------------------------------------------------------------------------
Animal actions: Animal and plant mobility is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand. A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock. This is an example of physical weathering.
---------------------------------------------------------------------------------------------------------
Ice wedging: Ice wedging ,sometimes known as frost wedging ,can also cause rocks to break apart. Ice wedging causes cracks in rocks to expand as water seeps in and the water freezes and expands opening the crack further. Rocks formed under pressure deep within earth can become exposed at the surface. This is physical weathering
----------------------------------------------------------------------------------------------------------
Oxidation: Oxidation is another kind of chemical weathering. It occurs when oxygen from air dissolves in water and combines with chemicals in the rocks to form oxides. if the rock contains a lot of iron, then oxidation produces a brown material called iron oxide. This looks like rust on the rock.
What is the difference between weathering erosion and deposition?Weathering is the chemical and mechanical breakdown of exposed rock. The chemical changes alter the minerals and make them softer, and mechanical weathering physically breaks rock into smaller and smaller pieces.
Erosion is the REMOVAL of those chemically and mechanically softer and broken pieces of rock from their original locations, by gravity, water, ice or wind. Erosion is transport (and as a result, fresh unaltered rock is exposed to wind, water and weather, and THAT becomes weathered in turn). The material being transported is ‘sediment’: sand, silt, mud and gravel.
Deposition is when the weathered and eroded (transported) material is dropped and settles down elsewhere, forming a ‘deposit’ of transported rock material.
If this deposit remains undisturbed long enough, and is buried by enough arriving material, it will eventually go through compaction and chemical reactions forming cement between the grains - thus resulting in a brand new, sedimentary rock.
Weathering, erosion, transport, deposition, compaction and cementation are part of the ‘rock cycle’.
How can the complete rock cycle be described?Let’s start with basalt that form at mid ocean spreading centers. At mid ocean spreading centers rock material from the earth’s mantle continuously melts due to continuous decreasing in pressure from the oceanic crust spreading at this point. The molten rock quickly cools at the earth’s surface and forms rock known as basalt that makes up the oceanic crust all over the world. The newly produced oceanic crust rock slowly moves towards a boundary with a continental crust where the oceanic crust subducts beneath the continental crust due to the oceanic crust having a higher density than the continental crust. This is where things get a bit more interesting.

Which of the following does not yield wool ? (a) yak (b) camel (c) goat (d) woolly dog
Explanation:Why is option A (yak) not correct?
The Himalayan region is home to the yak, a type of cattle. They have a reputation for having long, shaggy hair, which is used to create many different textiles, including wool. Yak wool is popular because it is soft, warm, and long-lasting and is frequently used to manufacture clothes and blankets.
Why is option B (camel) not correct?Camels are widely known for their capacity to survive in difficult desert situations, and their wool is a valuable resource in many parts of the world. Clothing, rugs, and other textiles are frequently made from camel wool because it is cosy and soft.
Why is option C (goat) not correct?Goats are another typical source of wool, especially in warmer locations where other types of wool are less common. Depending on the breed of goat and the quality of the wool, the term "mohair" or "cashmere" is frequently used to describe the wool from goats. Cashmere is appreciated for its warmth and luxurious feel, while mohair is renowned for its softness, sheen, and insulating qualities.
Why is Option D (woolly dog) correct?Despite the fact that there are numerous dog breeds with long, shaggy hair, none of them actually produce true wool. Dog hair is not often used to produce textiles since it is formed of a different kind of fibre than wool. Although some dog hair can be spun into yarn and used for crafts, it is not regarded as a true wool and is not widely utilised for the manufacturing of textiles.

In blood vessels innervated by only sympathetic axons, increased sympathetic stimulation causes the vessels to constrict while decreased sympathetic stimulation causes the vessels to dilate.
Blood vessels are the hollow tube-like structures that function to carry blood to different parts of the body. There are three types of blood vessels: arteries, veins and capillaries. Arteries carry blood away from the heart, veins carry blood to the heart and capillaries mediate the exchange of oxygenated and deoxygenated blood at the target location.
Sympathetic axons are the the one that connect with the blood vessels having large diameters. These axons therefore help in regulation of blood pressure of the body.

years, she repeated the measurements and observed that the tree gained 74 kg (164
lbs) but the soil had not changed much at all (only lost 57 g, approximately 0.12 lbs).
1. Use evidence, from the results, to explain that the idea that the mass of a tree
comes from the soil, is incorrect. 2 points
2. Why is it incorrect to say that the tree's mass comes from sunlight? 1 point
3. If the mass of the tree does not come from the soil or sunlight, explain the trees
increase in mass. 2 points
Explanation:
The fact that the soil did not change significantly after five years, while the tree gained 74 kg, suggests that the tree's mass did not come from the soil alone. If the tree had gained all its mass from the soil, the soil would have lost an equivalent amount of mass, which did not occur. Therefore, this evidence suggests that the mass of a tree does not come solely from the soil.
While sunlight is necessary for photosynthesis, which allows the tree to produce glucose, the mass of a tree does not come directly from sunlight. Rather, the tree uses the glucose produced during photosynthesis to build its own tissues, such as leaves, branches, and roots. Therefore, while sunlight is necessary for the tree to grow, it is not the source of the tree's mass.
The tree's increase in mass is primarily due to the process of photosynthesis. During photosynthesis, the tree uses energy from sunlight to convert carbon dioxide and water into glucose, which it then uses to build new tissues. Additionally, the tree may have also taken up nutrients, such as nitrogen and phosphorus, from the soil, which it incorporated into its tissues. However, it's important to note that the majority of the tree's mass comes from the carbon that it takes up during photosynthesis, rather than the nutrients in the soil.

Temperatures that might be too excessive or too low can severely harm and, in the intense temperature ranges, kill the cellular via their impact at the cellular membrane.
Physiologically ordinary intracellular pH is maximum generally among 7.0 and 7.4, even though there may be variability among tissues (e.g., mammalian skeletal muscle has a tendency to have a pHi of 6.8–7.1). There is likewise a pH version throughout special organelles, that can span from round 4.5to 8.0.
Water concentration:
Water molecules flow into and out of the cell at an identical fee, so the length stays constant. then a cell. This method of water attention is better within the cell than outside. Thus, water flows out of them, inflicting them to shrivel or maybe die.
Salt concentration:

Answer:
Why is eating pizza an external source of energy for the body? Why is ATP an internal source of energy?
Answer:
Eating pizza provides the body with an external source of energy because it contains nutrients such as carbohydrates, fats, and proteins that can be broken down by the body's digestive system to release energy. Once these nutrients are absorbed into the bloodstream, they are transported to the body's cells where they are used as fuel to generate ATP (adenosine triphosphate), the primary energy currency of the body.
On the other hand, ATP is an internal source of energy because it is produced by the body's own metabolic processes. ATP is synthesized through cellular respiration, a series of chemical reactions that occur within the cells of the body. During this process, nutrients such as glucose are broken down to release energy, which is then used to synthesize ATP. Once formed, ATP can be used by the body's cells to power a wide range of biological processes such as muscle contraction, protein synthesis, and nerve impulse transmission.
In summary, external sources of energy such as food provide the raw materials that the body needs to synthesize ATP internally, which is then used as the primary source of energy for various cellular processes.
