Q: What occurs when spores from two parents fuse and form a zygospore? Read this paragraph and choose the correct option from the provided answers: The majority of fungi can reproduce both asexually and sexually. This allows them to adjust to conditions in the environment. Yeast reproduce asexually by budding. Other fungi reproduce asexually by producing spores. Sexual reproduction occurs when spores from two parents fuse and form a zygospore. Choices: - twins - asexual reproduction - internal reproduction - sexual reproduction A:
sexual reproduction

Q: Which type of arthritis causes the immune system to attack joints? Read this paragraph and choose the correct option from the provided answers: In rheumatoid arthritis, the immune system attacks joints. This causes joint damage and pain. Choices: - Osteoarthritis - Gout - Spondylarthropathies - rheumatoid A:
rheumatoid

Q: Q: In prokaryotes, what are the regions called that repressors bind to? Read this paragraph and choose the correct option from the provided answers: For a bacteria, many aspects of gene regulation are due to the presence or absence of certain nutrients. In prokaryotes, repressors bind to regions called operators that are generally located immediately downstream from the promoter. Activators bind to the upstream portion of the promoter. Choices: - elements - enablers - consumers - operators A:
A: operators

Question: Q: What type of waves start when a source of energy causes a disturbance in the medium? Read this paragraph and choose the correct option from the provided answers: Mechanical waves are waves that transfer energy through matter, called the medium. Mechanical waves start when a source of energy causes a disturbance in the medium. Types of mechanical waves include transverse, longitudinal, and surface waves. Choices: - fluid waves - mechanical currents - magnetic waves - mechanical waves A:
Answer: mechanical waves

Q: What is the name for the stratospheric gas layer that protects living things from uv radiation? Read this paragraph and choose the correct option from the provided answers: The stratosphere contains a layer of ozone gas. Ozone consists of three oxygen atoms (O 3 ). The ozone layer absorbs high-energy UV radiation. As you can see in Figure below , UV radiation splits the ozone molecule. The split creates an oxygen molecule (O 2 ) and an oxygen atom (O). This split releases heat that warms the stratosphere. By absorbing UV radiation, ozone also protects Earth's surface. UV radiation would harm living things without the ozone layer. Choices: - carbon layer - atmospheric layer - toposphere - ozone layer A:
**Answer**
ozone layer

(Q).
Q: Very large stars eventually become what extremely dense space regions, which are so dense that no light can escape from them? Read this paragraph and choose the correct option from the provided answers: The largest-mass stars become black holes . These extremely large stars end their life in the same way as a medium-mass star in that they become a supernova. After the outer layers are blown away in the supernova, however, the core of the star shrinks down in volume but still has a huge mass. The density of this object is extremely high, even denser than neutron stars. This dense object will have a gravitational force so large that not even light can escape from the body. (A companion topic to this occurs in The General Theory of Relativity where we see than extremely strong gravitational attraction can even attract light. ) These objects appear black because light cannot leave them, that is, they pull all light back to their surface. Black holes capture everything nearby due to their massive gravity and so they grow in size. Black holes are a common topic for science fiction but keep in mind, they are simply a very dense ball of matter with intense gravitational attraction. Choices: - worm holes - dark matter - moons - black holes A:
(A).
black holes
