Seismic waves are waves produced by earthquakes. This occurs
when rocks under the earth suddenly break or explode. There are two MAIN TYPES
of seismic waves called body waves and surface waves.
<span>Body waves have the capacity to travel through the Earth's
inner layers. They have a higher frequency and they are the ones that first
occur under water at the onset of an earthquake. They can be subdivided
into two types, the primary and secondary waves that arrive at seismic records
one after another.
Surface waves can only traverse through the surface of the planet like ripples
in the water. These waves can easily be detected on a seismogram result. These
waves arrive after body waves and they are the ones mostly responsible for
damages and destruction bought by earthquakes.</span>

Ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
<span>As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.</span>
2 or more different atoms are combined in definite proportions in any compound.
I believe it is A
sorry if I'm wrong but I hope it helps!
please make my answer brainliest!!
Thanks!!
Q2. The answer is <span>C. Gymnosperms.
</span>
The word 'Gymnosperms'<span> is derived from two greek words: 'gymnos' = naked and 'sperm' = seed. Literally, their seeds are naked, i.e. they </span>do not form inside an additional structure. Their seeds develop on the surface of scales modified to form cones. This group of plants <span>include pine trees, cycads, and cedar trees.
Q3. The answer is </span><span>A. Angiosperms.
Angiosperms or flowering plants are seed-producing plants, just like Gymnosperms. Their seeds</span> form inside additional structures known as fruits. This group is the most diverse group of plants and include nearly 300,000 species. Angiosperms include <span>grasses, roses, maple trees, and many other plants with flowers.
Q4. The answer is </span><span>B. Lichen.
Lichen consists of hyphae (just like other fungi) that surround cells of </span><span>green algae or other photosynthetic organisms. This partnership between fungi and algae is known as mutualistic symbiosis. As in any other mutualistic symbiosis, both partners have benefits: fungi gain nutrients from algae and algae gain protection from fungi.
</span>
Q5. The answer is <span>C. Vertebrate.
Vertebrates are organisms with an</span><span> interior skeleton, or endoskeleton, and a backbone. Unlike vertebrates, invertebrates do not have a backbone or interior skeleton. The basic body plan of vertebrates includes vertebral column and/or notochord, the gastrointestinal tract below the notochord and the spinal cord above the notochord. Vertebrates include fish, amphibians, reptiles, birds, and mammals.
</span>
Q6. The answer is <span>B. Invertebrate.
Invertebrates are organisms without an internal skeleton and backbone. The main difference between vertebrates and invertebrates is that vertebrates have backbone and internal skeleton and invertebrates lack in those structures. Invertebrates</span> include all animals that are not vertebrates and include about 97% of all animals. Some of them are <span>insects, sea anemones, and worms.
Q7. The answer is </span><span>A. Bilateral Symmetry.
Bilateral symmetry </span><span>is symmetry around a single line. That means that only one plane divides an organism into two matching halves, left and right. Thus, this type of symmetry is also known as left-right symmetry. Word 'bilateral' comes from two Latin words: 'bi-' means 'two' and 'latero' means 'side', literally 'bilateral' = 'two sides'. Human beings are the example of organisms with bilateral symmetry.
Q8. The answer is </span><span>C. Asymmetry
</span>
Asymmetry means without symmetry. The word 'asymmetry' is derived from two Greek words: 'a-' = 'not' and 'symmetros' = symmetry, <span>commensurable. Not all animals are symmetric. There are some species that show asymmetry, such as some sponges and flatfish.
Q9. The answer is </span><span>B. Radial Symmetry.
A symmetry around any point is radial symmetry. The body of radially symmetric organisms can be divided into equal parts about a central point and they have </span>no left or right side of the body. This type of symmetry is characteristic for sea stars, sea cucumbers, sea anemone, jellyfish, corals.
