Answer:
Teaching about energy and physical processes is supported by 7 key concepts:
2.1 Earth is constantly changing as energy flows through the system. Geologic, fossil, and ice records provide evidence of significant changes throughout Earth's history. These changes are always associated with changes in the flow of energy through the Earth system. Both living and non- living processes have contributed to this change.
2.2 Sunlight, gravitational potential, decay of radioactive isotopes, and rotation of the Earth are the major sources of energy driving physical processes on Earth. Sunlight is a source external to Earth, while radioactive isotopes and gravitational potential, with the exception of tidal energy, are internal. Radioactive isotopes and gravity work together to produce geothermal energy beneath Earth's surface. Earth's rotation influences global flow of air and water.
2.3 Earth's weather and climate are mostly driven by energy from the Sun. For example, unequal warming of Earth's surface and atmosphere by the Sun drives convection within the atmosphere, producing winds, and influencing ocean currents.
2.4 Water plays a major role in the storage and transfer of energy in the Earth system. The major role water plays is a result of water's prevalence, high heat capacity, and the fact that phase changes of water occur regularly on Earth. The Sun provides the energy that drives the water cycle on Earth.
2.5 Movement of matter between reservoirs is driven by Earth's internal and external sources of energy. These movements are often accompanied by a change in the physical and chemical properties of the matter. Carbon, for example, occurs in carbonate rocks such as limestone, in the atmosphere as carbon dioxide gas, in water as dissolved carbon dioxide, and in all organisms as complex molecules that control the chemistry of life. Energy drives the flow of carbon between these different reservoirs.
2.6 Greenhouse gases affect energy flow through the Earth system. Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, are transparent to much of the incoming sunlight but not to the infrared light from the warmed surface of Earth. These gases play a major role in determining average global surface temperatures. When Earth emits the same amount of energy as it absorbs, its average temperature remains stable.
2.7 The effects of changes in Earth's energy system are often not immediately apparent. Responses to changes in Earth's energy system, input versus output, are often only noticeable over the course of months, years, or even decades.

Which two conditions do most seeds need in order to germinate?
A. Adequate sunlight
B. Enriched soil
C. Adequate water
D. Warm temperatures
Answer:
I believe it is a and c because plants need sunlight and water
Explanation:
The correct answer of the question about seed germination is that Adequate water and Enriched Soil are the two most important condition in order to germinate seed.
What do you mean seed germination?The fundamental process by which many plant species develop from a single seed into a plant is known as seed germination. This method has an impact on crop output and quality.The growth of a seedling from an angiosperm or gymnosperm seed is a frequent example of seed germination.Rapid water uptake by the seeds during the early stages of germination causes swelling and optimal temperature induced softening of the seed coat. Imbibition is the name given to this phase. Enzymes are activated to begin the growth process. The seed starts to create proteins, respire, and metabolise the food that has been stored after activating its internal physiology. This is the lag phase of seed germination.The seed coat bursts, allowing the radicle to emerge and develop into a main root. The seed begins to take up water from underground. After the radicle and plumule have emerged, the shoot begins to ascend.The seed cell lengthens, divides, and becomes metabolically active in the last stage of seed germination to produce the seedling.
Thus, we can conclude that after analysing and understanding the above given theory the best two realistic conditions in order to germinate good quality of seeds can be that Soil should be enriched and Adequate water supply should be there.

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?
Answer:
This question is incomplete, the complete question is as follows:
- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.
What percentage of offspring are expected to be chestnut?
The answer is 0%
Explanation:
This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.
According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;
BB - B only
bb - b only
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
Bb, Bb, Bb, Bb
All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0% of offspring are expected to be chestnut.
Answer:
its 0% love

EOC Biology STAAR Test Prep
In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codiminant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes.
O only
A or B only
A, B or O only
A, B, AB, or O
Please explain, also this is not a test its a test PREP
Answer:
D. A, B, AB, or O
Explanation:
We can start by visualizing all the possible genotypes of the offspring by drawing a Punnett square, which is a visual representation of the different possible combinations of alleles:
Individual 1 = AO, Individual 2 = BO
A O
B AB BO
O AO OO
Here we can see that there are 4 possible genotypes: AB, BO, AO and OO based on the alleles of the parents. Now we can match the genotypes to phenotypes to answer the question:
A and B are codominant, meaning that both will be expressed equally if both are present. Therefore the genotype AB will result in an AB phenotype.
Next, since A and B are both dominant over O, they are the alleles that will be expressed in the phenotype if paired with an O. This means that the genotype AO will result in an A phenotype, and likewise, genotype BO will result in phenotype B.
Finally in the genotype OO, although O is a recessive allele, there are no dominant alleles here to mask them, therefore O is expressed in the phenotype.
Hence, from the genotypes AO and BO, the possible offspring genotypes are AB, BO, AO and OO, translating to the possible phenotypes: A, B, AB or O.

Explanation:
which part of cellular respiration provide most of the energy to run
Answer: The electron transport chain.
Explanation:
Cellular respiration is defined as the mechanism by which living organisms converts organic substances from food such as glucose with the use of oxygen into energy-carrying biomolecules (e.g. adenosine triphosphate or ATP). There are different stages of cellular respiration which includes:
--> glycolysis,
--> pyruvate oxidation,
--> the citric acid or Krebs cycle, and
--> oxidative phosphorylation.
The oxidative phosphorylation also referred to as the ELECTRON TRANSPORT CHAIN occurs in the inner membrane of the mitochondria. It transfers electrons donated by the reduced electron carriers NADH and FADH2 (obtained from glycolysis, the citric acid cycle or fatty acid oxidation) through a series of electrons acceptors, to oxygen.
The electron transport chain is said to produces most of the energy which is 34 ATP molecules, as compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle.

Sophia discovered two objects in space with the help of her telescope. She noted down the characteristics of the objects in the chart below.
Which of these statements is most likely correct about Object 1 and Object 2 discovered by Sophia?
A. Object 1 is an inner planet and Object 2 is a comet.
B. Object 2 is an inner planet and Object 1 is a comet.
C. Object 1 is an outer planet and Object 2 is an asteroid.
D. Object 2 is an outer planet and Object 1 is an asteroid.
Answer:
C. Object 1 is an outer planet and Object 2 is an asteroid.
Explanation:
While inner planets can have moons, many moons are a more common feature of outer planets (ex. Jupiter has 79 moons, while Mars has 2). Plus, moons don't orbit asteroids or comets since moons are usually larger. This rules out any of the options involving Object 1 being an inner planet, comet, or asteroid. As for object two, both an asteroid or a comet would make sense as they both have irregular shapes. The only answer that has Object 1 as an outer planet is C. Also Object 1 has rings, which shows that it's an outer planet.

What types of food molecules make up chicken? (Carbs, Proteins, and/or Fats?)
no links!!
but its fats right??
Answer:
Fats
Explanation:
Chicken contains many different amino acids with different R-groups. In particular, chicken contains a large number of Tryptophan amino acids, which are amino acids that contain the side chain known as “indole”.
The type of food molecules that make up chicken is Proteins. It generally contains about 20% of proteins.
What do you mean by Food molecules?Food molecules are those which give energy to living organisms and contain chemicals that are required for the growth and repair of cells and their functions in the body of living organisms.
Proteins are the polymers of amino acids, which are linked via peptide bonds. The side chains of amino acids are varied from one to another. These side chains provide stability to the amino acid sequence. Mostly, the side chain of tryptophan and arginine gives the makeup to the food molecules of chicken.
Therefore, the type of food molecules that make up chicken is Proteins.

Air at the equator is warm and has a ______density, which creates ________ in comparison to the air at the poles.
Answer:
Lower, low pressure
Explanation:
The temperature at equator are mostly higher than at the poles almost all times of year. This high temperature causes air at the equator to warm up quickly and thus, the air density reduces and it becomes lighter. Now, light air rises upwards. Thus, creating a low pressure region at equators. This low pressure causes the air near the poles gush towards the equator.
Hence, the blanks will be filled with the words
Lower, low pressure.
