Two major scientific discoveries provide strong support for the Big Bang theory:
• Hubble’s discovery in the 1920s of a relationship between a galaxy’s distance from Earth and its speed
• the discovery in the 1960s of cosmic microwave background radiation.
1. Hubble’s discoveryin 1924 astronomer Edwin Hubble used a technique pioneered by Henrietta Leavitt to measure distances to remote objects in the sky.Hubble used spectroscopic red-shift data to measure the speeds these objects were travelling then graphed their distance from Earth against their speed.He discovered that the speed at which astronomical objects move apart is proportional to their distance from each other2. discovery in the 1960s of cosmic microwave background radiationOn May 20, 1964, American radio astronomers Robert Wilson and Arno Penzias discovered the cosmic microwave background radiation (CMB)It states that the ancient light that began saturating the universe 380,000 years after its creation.It also supports the big bang theoryThus, Two major scientific discoveries provide strong support for the Big Bang theory:
• Hubble’s discovery in the 1920s of a relationship between a galaxy’s distance from Earth and its speed
• the discovery in the 1960s of cosmic microwave background radiation.

What is the locomotory structure of yeast
Answer:
Yeast cell structure
Each yeast cell has a distinct cell wall enclosing granular cytoplasm, within which can be seen a large vacoule and a nucleus (Fig. 214). The vacuole varies much in size according to the state of activity of the cell.
Yeast contains almost the same organelles of a mature eukaryotic cell. Nucleus, Golgi apparatus, mitochondria, endoplasmic reticulum, vacuole, and cytoskeleton are the most important one. Yeast cell particle size is typically of 5×10μm.
Explanation:
Yet, we don't always think of yeast as something remarkable. Instead, it's often perceived as plain or dull—a single-celled organism that, like a plant, lacks the ability to move on its own accord.

Why is the moisture of cirrus clouds mostly in the solid state?
A The higher altitude allows for lower temperatures, leading to frozen water crystals.
B. The density of the clouds creates solidified crystals.
C. The low amount of wind allows the clouds to form water crystals.
D. The higher altitude and farther distance from Earth's surface mean there is less gravity to form ice crystals.
Answer:
A The higher altitude allows for lower temperatures, leading to frozen water crystals.
Explanation:
These clouds are a signal of good weather conditions. They characterize for being at very high altitudes, reflecting the direction of the wind, which moves them and constantly changes their shapes.
The higher they are, the lower the temperatures, son water vapor turns into crystals, which are moved by the wind in different directions.
Cloud formation occurs when humid air ascends and suffers adiabatic cooling, due to the high. As the air gets higher in altitude, it´s density and pressure decrease, so the air tends to expand with elevation in response to the reduced pressure. Gases in expansion experiment adiabatic cooling, losing caloric energy as their molecules move getting farther away from each other. As the air gets higher, it gets colder, and hence, denser.

Explanation:
A school bus leaves school to drop students off at their homes. It travels in a loop that heads 2 miles west, then 1 mile north, then 2 miles east, then 1 mile south before arriving right back where it started (at school). What is the total distance the bus traveled and what is its displacement?
Answer:
[tex]6\ \text{miles}[/tex]
0
Explanation:
The distance traveled in the loop is [tex]2+1+2+1=6\ \text{miles}[/tex].
The journey starts and ends at the same point. Displacement is the shortest distance between the starting and ending of a journey.
Here, the bus leaves and arrives at the same point after the completion of the journey so, the displacement of the bus is [tex]0\ \text{mile}[/tex].

solar energy from the sun is converted into chemical energy that is stored in the bonds of glucose molecules
chemical energy that is stored in the bonds of glucose molecules is converted to energy stored in ATP molecules
chemical energy that is stored in the bonds of glucose molecules is converted to energy stored in ATP molecules
energy stored in the bonds of ATP molecules is released by breaking off the bond with the last phosphate group during cellular respiration
energy stored in the bonds of ATP molecules is released by breaking off the bond with the last phosphate group during cellular respiration
Thermal energy from making smores is converted into chemical energy in the bonds of glucose molecules
Answer:
chemical energy that is stored in the bonds of glucose molecules is converted to energy stored in ATP molecules
Explanation:
Cellular respiration is the process of extracting energy from glucose into Adenosine triphosphate (ATP). That is glucose is converted into ATP.
The process of cellular respiration involves oxygen from the air we breathe mixing with glucose, thereby breaking the glucose to give carbon dioxide and water as the end product. During this process, ATP is released.
One molecule of glucose can be converted to get about 38 molecules of ATP.

2) cream - 25%
bay - 25%

3) co-dominance
Explanation:
Ok so a run down on Punnett Squares, all you have to do is put the parent's genes on the top and right hand side and combine those two genes in the middle as I did in the picture. Now, co-dominance, this basically means that there is no dominant allele. For example, imagine a white flower (W) and a red flower (R). If these two plants were to breed, you would get a pink flower (WR). This means the red allele and the white allele are both co-dominant. It is basically a combination of both genes that result in a mixed phenotype of the two genes, aka red and white makes pink. This is also how you get an AB blood type.

Answer: ok so im so mixed up between A & C
Explanation: because Deoxyribonucleic acid (DNA) is a molecule that contains the instructions needed for an organism to develop and function. These instructions are stored as a code made up of 4 chemical bases: adenine (A), guanine (G), cytosine (C) and thymine (T). butttttt its simlier to a gene : segment of a DNA molecule (a sequence of bases) Which that'd be A ... that codes for a particular protein and determines the traits (phenotype) of the individual. A gene is the basic unit of heredity in a living organism., im pretty sure its C but it could also be A... hope this helps :/. good luck!!

Which is a non-Mendelian trait?
A. A trait controlled by many genes
B. A trait with a clearly dominant form
C. A trait controlled by one gene
D. A trait with two alleles
Answer:
The answer would be A.
Explanation:
Non-Mendelian traits are traits that are not passed down with dominant and recessive alleles from one gene. Examples of polygenic traits are hair color and height. ... Other traits, such as blood type, show codominance, where there is no dominant or recessive allele.
A non-Mendelian trait would be a trait that is controlled by many genes. The right option would be A.
Mendelian traits are traits that obey the principles of the Mendelian laws While non-Mendelian traits simply do not conform with the principles and laws of Mendel.
A trait that is Mendelian would have the following:
Show simple dominance or recessive formControlled by a single geneEach gene must have 2 alleles. The 2 alleles can be the same (homzygous) or different (heterozygous).Thus, a trait that is controlled by many genes is clearly a non-Mendelian trait.

The answer is D. All of the above
Answer:D!!!!!!!!!
Explanation:
Freshwater wetlands can be found All of the above.
What are Freshwater wetlands?At least part of the year, a wetland is completely submerged in water. This seasonal flooding has varying levels of intensity and duration. Transitional areas include wetlands.
Since they have aspects of both, they are neither entirely on dry land nor entirely beneath water. The vegetation that surrounds a marsh depends on how saturated the soil is. Wetland plants have special adaptations to their hydric (watery) soil.
Hydrophytes are plants that grow in wetlands. Wetlands that experience seasonal dryness or have slow-moving water can frequently host trees and other hardy vegetation.

DNA replication requires all of the following EXCEPT: a template, that is, a strand or strands to be copied. the monomers that are assembled into the new strand, including dCTP. the enzymes that carry out the process, including primase. the enzymes that carry out the process, including topoisomerase. Actually, all of these are required for DNA replication.
Answer:
Actually, all of these are required for DNA replication.
Explanation:
This is because DNA replication is the process where double stranded DNA are copied and produced from the parent DNA molecule. For DNA replication to occur there must be a strand of DNA that must be copied, the monomers from the parent molecule, the enzymes that carry out replication process, primase and topoisomerase.

Which geologic term or phrase explains why the reason rock layers typically form parallel to each other? Cross-cutting relationships Original horizontality Superposition Unconformities
Answer:
Original Horizontality Principle is the Relative Chronology Principle which states that sediments are always deposited in horizontal layers. Any geological phenomenon that changes the horizontality is always after sedimentation.
Explanation:
Answer:
Original Horizontally
Explanation:
First of all, the principle of original horizontality explains why sediments form horizontal and parallel layers. Rocks broken down by weathering are distributed according to how they retain the least energy.
2. Scientists use the term "unconformity" to refer to a place in a body of rock where rock is missing. Unconformities lead geologists to hypothesize about past events, but they may not be able to find conclusive proof for their hypotheses. Some types of rock weather more quickly than others, further complicating the analysis of rock layers.
3. According to the Law of Superposition, the bottom layer is generally the oldest layer of rock. Therefore, fossils found in the lower strata are older in relation to fossils found in higher rock layers.
4. Picture Below (at the end it mentions cross-cutting relationships)
