Answer the following question given this paragraph: Vascular Plants The vascular plants are the dominant and most conspicuous group of land plants. There are about 275,000 species of vascular plants, which represent more than 90 percent of Earth's vegetation. Several evolutionary innovations explain their success and their spread to so many habitats. Vascular Tissue: Xylem and Phloem The first fossils that show the presence of vascular tissue are dated to the Silurian period, about 430 million years ago. The simplest arrangement of conductive cells shows a pattern of xylem at the center surrounded by phloem. Xylem is the tissue responsible for long-distance transport of water and minerals, the transfer of water-soluble growth factors from the organs of synthesis to the target organs, and storage of water and nutrients. A second type of vascular tissue is phloem, which transports sugars, proteins, and other solutes through the plant. Phloem cells are divided into sieve elements, or conducting cells, and supportive tissue. Together, xylem and phloem tissues form the vascular system of plants. Q: What type of plant is the dominant group of land plants? Choices: - grass plants - oxygen plants - thermal plants - vascular plants A:
vascular plants

Ques: Answer the following question given this paragraph: In polar covalent bonds, electrons are not shared equally between the two atoms, so one atom is slightly negative in charge and one is slightly positive in charge. In nonpolar covalent bonds, electrons are shared equally so the atoms remain neutral in charge. Q: Electrons are not shared equally between the two atoms in which type of covalent bonds? Choices: - wide - narrow - solar - polar A:
Ans: polar

They were the only living things until the first eukaryotic cells evolved about 2 billion years ago. Prokaryotes are still the most numerous organisms on Earth. Q: What were the first living things to evolve on earth? Choices: - eukaryotes - carbon - DNA - prokaryotes A:

Ans:prokaryotes
Ques:Answer the following question given this paragraph: 36.2 | Somatosensation By the end of this section, you will be able to: Describe four important mechanoreceptors in human skin Describe the topographical distribution of somatosensory receptors between glabrous and hairy skin Explain why the perception of pain is subjective Somatosensation is a mixed sensory category and includes all sensation received from the skin and mucous membranes, as well from as the limbs and joints. Somatosensation is also known as tactile sense, or more familiarly, as the sense of touch. Somatosensation occurs all over the exterior of the body and at some interior locations as well. A variety of receptor typesembedded in the skin, mucous membranes, muscles, joints, internal organs, and cardiovascular systemplay a role. Recall that the epidermis is the outermost layer of skin in mammals. It is relatively thin, is composed of keratin-filled cells, and has no blood supply. The epidermis serves as a barrier to water and to invasion by pathogens. Below this, the much thicker dermis contains blood vessels, sweat glands, hair follicles, lymph vessels, and lipid-secreting sebaceous glands (Figure 36.4). Below the epidermis and dermis is the subcutaneous tissue, or hypodermis, the fatty layer that contains blood vessels, connective tissue, and the axons of sensory neurons. The hypodermis, which holds about 50 percent of the body's fat, attaches the dermis to the bone and muscle, and supplies nerves and blood vessels to the dermis. Q: Somatosensation refers to what of the five senses? Choices: - balance - thought - sight - touch A:

Ans:
touch
