A)a tsunami
B)a volcano
C)a meteorite
D)an earthquake
Answer:
Option C, A meteorite
Explanation:
It is believed that a celestial object has hit the earth some 60 million years ago which has caused the extinction of dinosaurs. This celestial object is believed to be either an asteroid or a meteorite. As per the latest research by scientist it is believed that the dinosaurs were killed by the great tsunami caused by the collision of asteroid with planet earth.
Hence, option C is correct

How are fossils helpful in identifying ancestral and derived traits of organisms?
Give an example of how you could determine whether or not a trait was displaying incomplete dominance. What would you do? What would your results have to be for the trait to be incomplete dominant?
Answer:
If one has to find that whether a trait is showing incomplete dominance, then post-mating the two species should produce an offspring that will demonstrate an intermediate character of the two parents. For example, in snapdragon flower, when red-colored flowers were crossed with the white one, the F1 generation exhibited all pink flowers, that is, a trait, which is an intermediate between the two.
The outcomes, which shows that whether a trait is incomplete dominant are that the F1 generation should exhibit an intermediate character of the two parents, and the F2 progeny should exhibit a phenotypic and genotypic ratio of 1:2:1.
At which latitude would the sun be directly overhead at noon on April 21?
8°N
8°S
23.5°N
0°
On April 21, the sun would be directly overhead at the equator (0° latitude) as the sun is beginning to shift from the equator towards the northern hemisphere.
Explanation:On April 21st, the sun is directly overhead at the equator, which is at 0° latitude. During the equinox, which occurs roughly around March 21st and September 21st, the sun's rays are perpendicular to the Earth's surface at the equator. By April 21, the sun is beginning to shift northward but has not reached its maximum declination of 23.5°N, which happens during the summer solstice in late June. Therefore, the sun is still overhead at the equator at this time.

Which cell letter from the graphic organizer matches the fungus structure that releases digestive enzymes and absorbs digested organic material?
A. A
B. C
C. D
D. E
Answer: B hypha and D rhizoids
Explanation:
most of the fungi are saprotroph. They secretes digestive enzymes from hypha (B) of the mycelium on the dead and decaying matter. Digestive enzymes digest complex organic materials into simpler and soluble form in the external medium. With the help of root like structure called rhizoids (D) absorb nutrients from external medium into their body.
The fungal structure that releases enzymes and absorbs nutrients is the mycelium, made of hyphae; however, without the graphic organizer, an exact letter match can't be provided.
Explanation:The fungus structure that releases digestive enzymes and absorbs digested organic material is known as the mycelium, composed of hyphae. These hyphae are specially adapted to maximize their surface area to volume ratio, ensuring efficient nutrient absorption following the extracellular digestion that occurs when the fungus releases hydrolytic enzymes into the environment. Since the list of options (A, B, C, D, E) provided from the graphic organizer does not directly correspond to the detailed structure of fungus, none of the options can be chosen with confidence without seeing the graphic organizer itself.

A nurse is providing disaster care in an event that is known to involve gamma radiation. when admitting victims of the disaster, what should the nurse do to best reduce victims' risks of injury?
The right answer is Remove victims' clothing and have them wash thoroughly.
The doctrine of medical management of accidental contaminations with the presence of injured, burned or shocked victims (blast effect ), is clearly established and internationally recognized. It comes down to a golden rule: the medical emergency takes precedence over the radiological emergency. The management of accidental contaminations is essentially operational with a reflex phase where the emergency medical teams must deploy at the accident site an advanced medical post including chains of decontamination, undressing, and showers. The objective is to perform a medical sorting of the victims and to eliminate the radioactivity deposited on the clothes and the skin.

Solar energy from the Sun's rays is absorbed by the Earth's land and water surfaces. This absorbed energy is then radiated back to the atmosphere as infrared radiation. Most of the radiation cannot be transmitted and is absorbed by the atmosphere. This absorption adds heat to the atmosphere and helps keep the Earth warm enough to support life. The process described above is known as
Answer: The process described above is known as:
Thermal Radiation.
Explanation: Thermal radiation is an electromagnetic radiation generated by the thermal motion of particles in matter.
The greenhouse effect is the process where solar energy absorbed by the Earth's surface is radiated back as infrared radiation, which is mostly absorbed by greenhouse gases, thus warming the atmosphere.
The process described above, where solar energy is absorbed by the Earth's surface and then radiated back into the atmosphere as infrared radiation, most of which is then absorbed by the atmosphere and greenhouse gases, is known as the greenhouse effect. This effect helps to keep the Earth warm and is vital for sustaining life. The greenhouse effect is a natural process and without it, the Earth's average temperature would be significantly lower, making it inhospitable to most forms of life.
The incoming solar radiation, which is mostly in the form of shortwave radiation including visible light, ultraviolet, and some infrared, is absorbed by the land and oceans, heating the Earth's surface. This heat is then emitted as longwave infrared radiation. Greenhouse gases, such as water vapor, carbon dioxide, and methane, absorb this infrared radiation and then reradiate the heat back to the Earth's surface, maintaining the Earth's temperature.

The answer choices to this question are:
a. Learned helplessness.
b. Stimulus discrimination.
c. Aversive conditioning.
d. Vicarious learning.
The best answer choice is:
a. Learned helplessness
Explanation: Learned helplessness was studied by Seligman as a potential animal model of depression. Learned helplessness occurs when people or animals feel helpless to avoid negative situations. Martin Seligman first observed learned helplessness when he was doing experiments on dogs. He noticed that the dogs didn't try to escape the shocks if they had been conditioned to believe that they couldn't escape.
What is the correct order for the reactions of the calvin cycle?
The correct order for the reactions of the calvin cycle is Carboxylation → reduction → Regeneration.
What is calvin cycle?A series of chemical reactions known as the Calvin cycle, light-independent reactions, biosynthetic phase, dark reactions, or photosynthetic carbon reduction cycle of photosynthesis occurs during the phase of photosynthesis in which carbon dioxide and hydrogen-carrier compounds are converted into glucose.
Carbon dioxide is fixed during the first stage of the Calvin cycle, which is also the stage in which the light-independent processes begin. ATP and NADPH are responsible for the reduction of 3PGA to G3P during the second stage of the C3 cycle. After then, ATP and NADPH undergo a reaction that produces ATP and NADP+. RuBP is regenerated during the last stage of the process.
