Q: What is the leading cause of skin cancer? Read this paragraph and choose the correct option from the provided answers: Forms of radiation that cause cancer include ultraviolet (UV) radiation and radon ( Figure below ). UV radiation is part of sunlight. It is the leading cause of skin cancer. Radon is a natural radioactive gas that seeps into buildings from the ground. It can cause lung cancer. Choices: - artificial light - dehydration - smoking - sunlight A:
sunlight

Q: Humans possess greater diversity of what type, compared to laboratory animals? Read this paragraph and choose the correct option from the provided answers: Choices: - lifespans - elements - pathogens - genetics A:
(Answer)
genetics

Ques: Q: When atomic orbitals hybridize, the valence electrons occupy these? Read this paragraph and choose the correct option from the provided answers: When atomic orbitals hybridize, the valence electrons occupy the newly created orbitals. The Be atom had two valence electrons, so each of the sp orbitals gets one of these electrons. Each of these electrons pairs up with the unpaired electron on a chlorine atom when a hybrid orbital and a chlorine orbital overlap during the formation of the BeCl bonds. Choices: - newly created elements - newly developed orbits - expanded pathways - newly created orbitals A:
Ans: newly created orbitals

Q: What state of matter has a definite volume, but not a definite shape? Read this paragraph and choose the correct option from the provided answers: Liquids have a definite volume, but no definite shape. A gallon of milk will keep the same volume whether it is stored in a one-gallon milk jug or a ten-gallon barrel. The volume is the same, but the fluid will either fill the jug or spread out over the bottom of the barrel. Choices: - gas - solid - mixture - liquid A:
(A).
liquid

Ques:Q: A trait controlled by a single gene that has two alleles is given what name, after the scientist who studied inheritance? Read this paragraph and choose the correct option from the provided answers: A Mendelian trait is a trait that is controlled by a single gene that has two alleles. One of these alleles is dominant and the other is recessive. Many inheritable conditions in humans are passed to offspring in a simple Mendelian fashion. Medical professionals use Mendel's laws to predict and understand the inheritance of certain traits in their patients. Also, farmers, animal breeders, and horticulturists who breed organisms can predict outcomes of crosses by understanding Mendelian inheritance and probability. Choices: - darwinian trait - rosilin trait - carlinian trait - mendelian trait A:

Ans:mendelian trait

Question: Q: Of the four nerve plexuses, two are found at the cervical level, one at the lumbar level, and one at which level ? Read this paragraph and choose the correct option from the provided answers: Of the four nerve plexuses, two are found at the cervical level, one at the lumbar level, and one at the sacral level (Figure 13.24). The cervical plexus is composed of axons from spinal nerves C1 through C5 and branches into nerves in the posterior neck and head, as well as the phrenic nerve, which connects to the diaphragm at the base of the thoracic cavity. The other plexus from the cervical level is the brachial plexus. Spinal nerves C4 through T1 reorganize through this plexus to give rise to the nerves of the arms, as the name brachial suggests. A large nerve from this plexus is the radial nerve from which the axillary nerve branches to go to the armpit region. The radial nerve continues through the arm and is paralleled by the ulnar nerve and the median nerve. The lumbar plexus arises from all the lumbar spinal nerves and gives rise to nerves enervating the pelvic region and the anterior leg. The femoral nerve is one of the major nerves from this plexus, which gives rise to the saphenous nerve as a branch that extends through the anterior lower leg. The sacral plexus comes from the lower lumbar nerves L4 and L5 and the sacral nerves S1 to S4. The most significant systemic nerve to come from this plexus is the sciatic nerve, which is a combination of the tibial nerve and the fibular nerve. The sciatic nerve extends across the hip joint and is most commonly associated with the condition sciatica, which is the result of compression or irritation of the nerve or any of the spinal nerves giving rise to it. These plexuses are described as arising from spinal nerves and giving rise to certain systemic nerves, but they contain fibers that serve sensory functions or fibers that serve motor functions. This means that some fibers extend from cutaneous or other peripheral sensory surfaces and send action potentials into the CNS. Those are axons of sensory neurons in the dorsal root ganglia that enter the spinal cord through the dorsal nerve root. Other fibers are the axons of motor neurons of the anterior horn of... Choices: - cranial - vascular - peripheral - sacral A:
Answer:
sacral
