Fossil records indicate that between 80 million and 60 million years ago the structure of the horned dinosaur frequently underwent rapid changes separated by long periods of stability. This pattern of change best illustrates the concept of -
Answer:
punctuated equilibrium
Explanation:
The punctuated equilibrium theory is a model of evolution by bursts of speciation, which was proposed by the paleontologists Niles Eldredge and Stephen J. Gould (1972). The theory of punctuated equilibrium states that evolution is characterized by rapid changes followed by longer periods of stasis where little observable evolution seems to occur judging from the fossil record. The punctuated equilibrium theory does not propose that Darwin's evolutionary gradualism is wrong, but this theory suggests that important evolutionary changes occur in short periods of time that are linked to speciation events. In consequence, fossils record does not represent transitional forms because of their small population size compared to the observed in stasis periods.
You are replicating Gregor Mendel's famous experiment with sweet peas. The genotype for dominant smooth-seeded parent is designated AA, while the genotype for the wrinkled-seeded parent is aa. Using a punnet square predict the first generation for this cross. What are the genotypic and phenotypic ratios? SHOW ALL WORK.
Answer:
The correct answer is -
A. genotype ration = 1/1 or 100% of Aa.
B. phenotype = all smooth-seeded.
Explanation:
According to the question, in this experiment, the smooth seed is the dominant trait over the wrinkled seed. The wrinkled seed is recessive, therefore, represented by aa and dominant is represented by AA
gametes: A and A from smooth seeded parent and a and a from the wrinkled-seeded parent.
Punnett square:
A A
a Aa Aa
a Aa Aa
In this cross of F1 generation, all the offsprings are Aa in genotype 4/4 or 1/1 or 100 percent chances.
And phenotypically 100% chances of the smooth seed plants.

Certain mental problems are thought to be caused by not having enough
neurotransmitters. Why would a lack of neurotransmitters cause problems?
A. Neurons would not be able to receive sensory messages.
B. Neurotransmitters send signals from neuron to neuron.
C. Neurons would not be able to grow longer.
D. Neurons would not be able to move to new areas.
Answer:
B. Neurotransmitters send signals from neuron to neuron.
Explanation:
Lack of neurotransmitters may cause problems because neurotransmitters send signals from neuron to neuron.
The lack of neurotransmitters cause problems because neurotransmitters send signals from neuron to neuron. Therefore, option (B) is correct.
A neurotransmitter is a molecule that a neuron secretes to influence another cell at a synapse. Another neuron, a gland or muscle cell, or the target cell, could be the cell that receives the signal.
Your body cannot function without chemical messengers called neurotransmitters. Chemical signals, or "messages," are carried from one neuron (a nerve cell) to the next target cell by them. The following objective cell can be another nerve cell, a muscle cell or an organ.

Answer:
The correct answer is 4. Plateaus.
Explanation:
A plateau is a relatively flat, relatively high-lying part of the earth's surface that is wholly or almost wholly bounded by steeply sloping terrains. There is a pronounced slope on at least one side. The original flat area has mostly risen vertically as a whole due to geological factors. It may possibly have been cut by rivers, giving the impression of a hill or mountain landscape, but this is not it.

Summarize the differences between early succession, mid-succession, and late succession?
The pH of a solution is a measure of how acidic or basic it is. The greater the pH, the more basic the solution is. Corals and other marine invertebrates require less energy to make their exoskeletons and shells when ocean water is slightly basic. As carbon dioxide concentrations in Earth’s atmosphere rise, ocean water absorbs carbon dioxide and becomes more acidic. This process is called ocean acidification. How do you think ocean acidification will affect the coral reef?
Explanation:
Because coral reefs have limestone (calcium carbonate), the coral reefs will be greatly affected. The increase in hydrogen ions in the ocean will corrode the coral reef, making it inhabitable for species. This will affect the crabs that get their food and the community that lives within in it. Making countless of species to loose their lives and their way if living.

Cardiac output is the amount of blood pumped by the heart in one minute. Which of these will increase cardiac output?
decreased blood volume
increased physical activity
decreased metabolic activity
increased resistance in blood vessels
Physical activity will increase cardiac output. Therefore, the correct option is "B".
What is cardiac output?Cardiac output is related to the heart's health. It tells the amount of blood pumping in and out of the chambers of the heart. This mechanism helps in circulation of the blood throughout the body. The blood can be oxygenated and deoxygenated. The circulation of blood to the vital organs and the main organ brain is circulated through this process.
The calculation of the cardiac output is oxygen consumption in ml per minute is divided by the oxygen concentration in arterial blood and minus oxygen concentration in venous blood in the body.
Therefore, the calculation of the cardiac output helps in the identification of the heart's health.

What is the DNA sequence that was used for synthesizing this mRNA sequence? A.TTTgctatactatagtac ...
Answer:
The generated mRNA sequence will be AAACGAUAUGAUAUCAUG...
Explanation:
DNA consists of nucleotides, which are composed of nitrogenous bases that are called Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). These nitrogenous bases must pair with each other for the DNA molecule to be formed. In DNA, Adenine only pairs with Timine, while Guanine only pairs with Cytosine. In this case, we can say that the nitrogenous bases pair with other bases that are complementary to them.
The mRNA is formed from the DNA and the enzyme that produces the mRNA, uses the sequence of nitrogenous base pairs of DNA to produce the mRNA, however, the mRNA does not have the Thymine base, but the Uracil (U) base that pairs with Adenina. In this case, when the DNA contains the Adenine base, the mRNA produced will present the Uracil base. When the DNA has the Guanine base, the mRNA will have the cytosine base.
Thus, a DNA with the base sequence TTTgctatactatagtac will present an mRNA with the base sequence AAACGAUAUGAUAUCAUG ...
