X-rays _____.
are blocked by the ionosphere
are less dangerous than ultraviolet rays
have very long wavelengths
are not emitted by the sun
Answer:
have very long wavelengths
Explanation:
The first X-ray image was captured by Wilhelm Conrad Roentgen (1895), who accidentally discovered these rays while experimenting with vacuum tubes. X-rays are high-energy electromagnetic radiation with very long wavelengths (in the range of 0.01 to 10 nanometers, nm). They are shorter in wavelength than ultraviolet rays and longer than gamma rays. X-rays have energies ranging from 100 electron-volts (eVs) to 100 kiloelectron-volts (keVs). On the other hand, the radio waves are blocked by the planet's ionosphere and, therefore, they cannot reach the Earth.
an innovation among the dicynodonts that allowed them to fill brand new niches. an innovation among the dicynodonts that allowed them to fill brand new niches. the availability of previously occupied niches. the availability of previously occupied niches. the extinction of the dinosaurs (except the birds). the extinction of the dinosaurs (except the birds)., the evolution of humans.
Complete question:
If an increase in dicynodont species diversity (in other words, number of species) occurred soon after the Permian extinction, and if it occurred for the same general reason usually given for the increase in mammalian diversity following the Cretaceous extinction, then it should be attributed to
A) an innovation among the dicynodonts that allowed them to fill brand-new niches.
B) the availability of previously occupied niches.
C) the extinction of the dinosaurs (except the birds).
D) their out-competition of many other terrestrial organisms.
Answer:
B) the availability of previously occupied niches.
Explanation:
Some species could survive massive extinctions caused by severe natural catastrophes. Some of them were small animals that could hide in certain places that were useful for their protection during the catastrophe. Those animals, that for instance, could hide underground, were able to avoid extreme temperatures and highly toxic gas concentrations caused by the phenomenon. Catastrophes caused severe damage to the Earth´s surface, causing the extinction of many other animal and vegetal species, causing changes in the morphology of the ground, and in temperature. Animals that could survive found themselves in a whole different place. Many niches were now available to be re-occupied. Survivers could specialize in different feeding strategies, finding new different shelters, and developing new morphological characteristics that lead to a rapid diversification and speciation.
The human eye is filled with a clear fluid called the aqueous humor. The production, flow, and drainage of this fluid is an active and continuous process which keeps the healthy eye at an intraocular pressure of about 15 mmHg. If the drainage becomes obstructed, fluid accumulates in the eye resulting in an increase of this pressure to the 25 to 50 mmHg range and the clinical onset of glaucoma. What is the pressure of 30 mmHg expressed in units of psi (pounds per square inch)
Answer:
The pressure will be "0.579 psi".
Explanation:
The given value is:
Hg,
= 30 mm
Density of mercury (Pm),
= 13600 kg/m³
As we know,
1 psi = 6895 N/m²
Now,
The pressure will be:
= [tex]30 \ mm \ of \ Hg[/tex]
= [tex]30\times 10^{-3}\times Pm\times g[/tex]
On substituting the given values, we get
= [tex]30\times 10^{-3}\times 13600\times 9.8[/tex]
= [tex]3,998,400\times 10^{-3}[/tex]
= [tex]3,998.4 \ N/m^2[/tex]
So,
The pressure of 30 mm of Hg will be:
= [tex]\frac{3,998.4}{6895}[/tex]
= [tex]0.579 \ psi[/tex]

At a deep sea whale fall, the Atlantic hagfish, the crustaceans, and the sand make up which of the following?
Answer:
I would say part of an ecosystem and community.
Explanation:
An ecosystem is a biological community of interacting organisms and their physical environment .In the bottom of the sea,there are already many animals living here and when the whale fall appears at the bottom of the ocean it becomes apart of the ecosystem as it provides them with food.
This is because when a whale dies, its body often falls to the seafloor. The whale's body then becomes food and shelter for organisms in the deep sea. This is called a whale fall. A deep-sea whale fall might support 200 different species for as long as 10 years! Larger species, such as Atlantic hagfish, are the first to arrive to feed on the whale flesh. Later, smaller species of snails and crustaceans come to eat the remaining flesh. Worms burrow into the sand beneath the whale body, and bacteria feed on the whale bones.
Answer:
Part of an ecosystem
Explanation:
The Atlantic hagfish and the crustaceans are living organisms. The sand is a nonliving part of the environment. An ecosystem is made up of living organisms and the nonliving parts of their environment. So, the Atlantic hagfish, the crustaceans, and the sand make up part of an ecosystem.

A.Grooves in the rocks and sediment deposits.
B.Fossil evidence of cold weather species.
C.Radioactive isotopes in the ice cores
D.Large glacial lakes still exist
Answer:
A.
Explanation:
There is also much climate evidence supporting continental drift, most notable of which is glacial activity. Alfred Wegener investigated this field and found an anomaly in the Permo-Carboniferous ice sheet that was found through glacial till deposits to have once covered all the southern major plates.

Answer:
The perception of pain throughout the body arises when neural signals originating from the terminals of nociceptors are propagated to second-order neurons in the spinal cord or brainstem, whereupon they are transmitted to specific higher-order brain areas (Price, 2000). Recent studies have begun to elucidate some of the molecular mechanisms underlying the transduction of noxious stimuli. Many stimuli have been found to activate ion channels present on nociceptor terminals that act as molecular transducers to depolarize these neurons, thereby setting off nociceptive impulses along the pain pathways (Price, 2000; Costigan and Woolf, 2000). Among these ion channels are the members of the transient receptor potential (TRP) family. To date, the most studied member of the TRP family is the TRPV1 receptor. This is because it is the only one activated by capsaicin, the compound in chili pepper responsible for its “hot” taste; also, inhibiting TRPV1 has been shown to have therapeutic value (DiMarzo et al., 2002; Cortright and Szallasi, 2004). Although we will focus on the presence of these channels in nociceptors, we note that they have been identified in many other cell types and in various cortical and subcortical areas (Toth et al., 2005). The transient receptor potential vanilloid 1 (TRPV1) channel is predicted to have six transmembrane domains and a short, pore-forming hydrophobic stretch between the fifth and sixth transmembrane domains (see Figure 5.1A). It is activated not only by the vanilloid capsaicin (Caterina et al., 1997), but also by noxious heat (>43°C) and low pH (Caterina et al., 1997; Tominaga et al., 1998), voltage (Gunthorpe et al., 2000; Piper et al., 1999), and various lipids (Julius and Basbaum, 2001; Caterina and Julius, 2001; Clapham, 2003; Cortright and Szallasi, 2004, Szallasi and Blumberg, 1999; Prescott and Julius, 2003; Jung et al., 2004; Bhave et al., 2003). In cells, TRPV1 is inactivated by its binding to PIP2 and is released from this block by PLC-mediated PIP2 hydrolysis (Prescott and Julius, 2003). TRPV1 is widely expressed in central nervous system (CNS) tissue and highly expressed in sensory neurons of the dorsal root ganglion [19]. This receptor also localizes to neurons that line the oral and nasal cavities [10], where it is found in a subpopulation of sensory afferent nociceptive nerve fibers [20].
(this is for question 1.)
Explanation:
Answer:
see explanation :)
Explanation:
a) R groups in the transmembrane domain should be hydrophobic while R groups in either terminus should be hydrophilic, and the TRPV 1 protein is synthesized on the ribosomes attached to the rough endoplasmic reticulum.
b) Cyclins cannot activate cyclin-dependent kinases which normally phosphorylate other proteins to move the cell through a cell cycle checkpoint.
c) Apoptosis will be induced and if NFAT2 cannot be phosphorylated, it will be able to inhibit ATF3 expression, which which enables activity of pGoG which will induce apoptosis.
d) If Calcineurin is inhibited, then the steps in this pathway that follow from calcineurin activation will be unable to block cell division/induce apoptosis. Since cancer is characterized by excessive cell division, this drug would be an inappropriate treatment for cancer.

What process causes a zygote (one cell) to become a blastocyst (hundreds of cells)
Answer:
Fertilization
Answer:
lastocyst formation
The zygote develops by mitosis, and when it has developed into 16 cells becomes known as the morula. Until this stage in development, all cells (blastomeres) are autonomous and not specified to any fate. In many animals, the morula then develops by cavitation to become the blastula.
Explanation:
By the if you want to know what type of system this is part of the reproductive system.
photosynthesis, respiration, volcanic eruption, decomposition
Answer:
-> photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
-> respiration: a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
-> volcanic eruption: Volcanic eruptions happen when lava and gas are discharged from a volcanic. Volcanic eruptions often cause temporary food shortages and volcanic ash landslides called Lahar. The most dangerous type of volcanic eruption is referred to as a 'glowing avalanche'.
-> decomposition: Dead organisms are broken down into smaller pieces by the process of decay.
Explanation:
Hope you get your answer correct!
Have a good day :D
Answer:
Photosynthesis: Photosynthesis is the process by which plants convert light energy to starch and chemical energy to manufacture their own food.
Respiration: Respiration is the process by which a living thing breathes in air. humans breathe in oxygen and breath out carbon dioxide, on the other hand plants breathe in carbon dioxide and breathe out oxygen.
Volcanic Eruption: Volcanic eruption is the process when a volcano sends out lava to the outer surface of the earth due to tectonic plate movements.
Decomposition: Decomposition is the process by which dead organic substances or decaying matters are broken down into simpler organic or inorganic matters with the help of natural processes.
