Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.
Nurse Evers suggested to Dr. Brodus to give the men fifty dollar for burial expense. Dr. Brodus was happy to offer men the fifty dollars because he knew that it would hold onto the men approaching back for treatment management.
I think all three ideas should be selected since they were all in the blue box so it seems like it’s included
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.
Answer:
on a tyrosine residue
bind to insulin
Explanation:
The insulin receptor substrate-1 (IRS1) is a signaling protein that can be phosphorylated on multiple tyrosine and serine/threonine residues. IRS1 contains several conserved domains including a pleckstrin (PH) domain and a PTB domain involved in protein phosphorylation and ligand binding. In the first place, IRS1 is phosphorylated on a tyrosine residue, and then IRS1 binds to insulin or the insulin-like growth factor-1 (IGF-1), thereby activating transduction pathways such as, for example, MAPK/ERK. Moreover, RS1 is also phosphorylated on serine residues, thereby triggering opposite effects in insulin-associated signaling.
