Answer:
Parent material is the underlying geological material (generally bedrock or a superficial or drift deposit) in which soil horizons form. Soils typically inherit a great deal of structure and minerals from their parent material, and, as such, are often classified based upon their contents of consolidated or unconsolidated mineral material that has undergone some degree of physical or chemical weathering and the mode by which the materials were most recently transported.
In pea plants the trait for being tall (T) is dominant over the trait for being short (t) and having green peas (G) is dominant to having yellow peas (g).
A heterozygous (for both traits) tall, green pea plant is crossed with a short, yellow pea plant.
Use T/t for height and G/g for color to answer the questions.
Part A
PARENT 1: What is the genotype of the heterozygous tall, heterozygous green parent?
PARENT 2: What is the genotype of the short, yellow parent?
Match the statements.
Answer:
PHOTOSYNTHESIS:
- Light energy is absorbed
- Glucose and oxygen are products
- Carbon dioxide and water are inputs
- Chemical energy is produced
CELLULAR RESPIRATION:
- Carbon dioxide and water are outputs
- Chemical energy is released
- Glucose and oxygen are inputs
- ATP, motion and heat energy are produced
Explanation:
- Photosynthesis is process by which autotrophic organisms synthesize their food (glucose) in the presence of sunlight. The process combines carbon dioxide (CO2) and water (H20) to produce glucose (C6H12O6) and oxygen (O2), by the energy derived from absorbing light. In the process, light energy is transformed to chemical energy (glucose). The reaction is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
- Cellular respiration is the opposite of photosynthesis as it involves the metabolic breakdown of glucose molecule to produce energy usable by the cell (ATP). Cellular respiration combines glucose and oxygen (inputs) to yield carbon dioxide and water (outputs). ATP, motion and heat energy are produced in the process. The equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O

ATG - CCG - AAT - TCG
Answer:
AAG GGU CUA AAA
it's U because RNA contain Uracil instead of Thymine
Answer:
AAG - GGU - CUA - AAA
Explanation:
This happens because in the RNA synthesis, Thymine is present in Uracil giving it a U symbol. The conversions between the bases go between Cytosine and Guanine, or Thymine (Uracil) and Adenine. Whenever you switch to the other strand, it becomes the opposite base for the other strand so they fit together perfectly in the chromosome or chromatid. Example: C - G contain opposite characteristics that fit so they only go together, Adenine or Guanine will not ever be present with either of those bases.
what is an important effect of mars low temperature and low air pressure
Standing on the ground and looking up, you are looking through the atmosphere. It might not look like anything is there, especially if there are no clouds in the sky. But what you don’t see is air – lots of it. We live at the bottom of the atmosphere, and the weight of all the air above us is called air pressure. Above every square inch on the surface of the Earth is 14.7 pounds of air. That means air exerts 14.7 pounds per square inch (psi) of pressure at Earth’s surface. High in the atmosphere, air pressure decreases. With fewer air molecules above, there is less pressure from the weight of the air above.
Pressure varies from day to day at the Earth’s surface - the bottom of the atmosphere. This is, in part, because the Earth is not equally heated by the Sun. Areas where the air is warmed often have lower pressure because the warm air rises. These areas are called low pressure systems. Places where the air pressure is high, are called high pressure systems.
A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation. Because of Earth’s spin and the Coriolis Effect, winds of a low pressure system swirl counterclockwise north of the equator and clockwise south of the equator. This is called cyclonic flow. On weather maps, a low pressure system is labeled with red L.
A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator. This is called anticyclonic flow. Air from higher in the atmosphere sinks down to fill the space left as air is blown outward. On a weather map, you may notice a blue H, denoting the location of a high pressure system.
How do we know what the pressure is? How do we know how it changes over time? Today, electronic sensors in weather stations measure air pressure. These sensors are able to make continuous measurements of pressure over time. In the past, barometers were used and measured how much air pushed on a fluid, such as mercury. Historically, measurements of air pressure were described as “inches of mercury.” Today, meteorologists use millibars to describe air pressure.
Air pressure depends on temperature and density.
When you inflate a balloon, the air molecules inside the balloon get packed more closely together than air molecules outside the balloon. This means the density of air is high inside the balloon. When the density of air is high, the air pressure is high. The pressure of the air pushes on the balloon from the inside, causing it to inflate. If you heat the balloon, the air pressure gets even higher.

the digestive system is responsible for breaking down food into usable nutrients for the body, which other organ system works with the digestive system to transport nutrients to all the muscles, organs, and cells in the body?
Answer:
Circulatory System
Explanation:
As soon as 5he digestive system has broken down the foods to their smallest unit, the circulatory system helps to move the nutrient to where they are needed.
Blood is a medium of transport in higher vertebrates and is being pumped by the heart and flows through network of capillaries. Blood also transport oxygen that helps in the breakdown of carbohydrates to produce energy and get rid of waste such as carbondioxide through the excretory system.
Instructions: Look at the motion graphs shown below. Match the descriptions here to the coorect graph.
Description a. A car moving at a constant speed stops and then moves in the opposite dorection at the same speed.
Description b. A car moving at a constant speed stops and then moves faster in the same diresction.
Description c. A car moving at a constant speed changes to a higher constant speed
Description d. A car moving at a constant speed changes to a lower constant speed.
Answer:
A-2
B-4
C-1
D-3
Explanation:
In description A, the car is first moving at a constant speed, which means it will have a constant slope. Then, it stops, which causes a slope of 0. Finally, it moves in the opposite direction, which will cause a negative slope. The second graph has a positive, zero, and negative slope; therefore, it fits A.
Description B has a constant slope, a zero slope, and a higher slope. Graph 4 goes up normally, then stops, and finally goes steeper. This fits description B.
Description C has a constant and then a higher slope. Graph 1, increases steadily and then sharply increases; which fits C.
Description D has a constant and then a lower slope. Graph 3 increases fast but then flattens, which matches the slopes in the description.
In a codon which of the nucleotides tends to be less important for determining the corresponding amino acid and why
Answer:
el sapo
Explanation:
Since many proteins share the same first two bases, the third base is the least important.
What is codon?A codon is a three-nucleotide (DNA or RNA) sequence that forms a unit of genomic information encoding a specific amino acid or signaling the end of protein synthesis (stop signals).
There are 64 different codons, 61 of which specify amino acids and three of which serve as stop signals.
As a result of genetic code degeneracy, many amino acids share the third base and differ only in the first two bases, making the third base less important.
Stop codons are base triplets that do not code for amino acids; there are three stop codons: TAG, TAA, and TGA.
Thus, these tends to be less important for determining the corresponding amino acid.

What is fossils?Fossils generally helps in relative dating of rocks. The Trilobites are considered the oldest in this rock sequence when we apply the principle of superposition of strata. The principle states that "in an undeformed/undisturbed sequence of rock, the oldest is always at the bottom while the youngest is on top". This principle therefore explains why the Trilobites at the base are considered the oldest.
How is the layer of iridium used to tell the relative age of different rock strata and fossils" it can be said that rock strata and fossils can have there ages detected by following the layer of irudium over the newer ones recently dropped.
It is important to note that iridium is an element that has had its deep root on earth for the longest of times Because of this unending deposition of iridium all over the earth. There is a particle of iridium on most rock strata and fossils allover the earth. Now rock strata and fossils can have there ages detected by following the layer of irudium over the newer ones recently dropped.
