Answer the following question given this paragraph: A vesicle is a small, spherical compartment that is separated from the cytosol by at least one lipid bilayer. Many vesicles are made in the Golgi apparatus and the endoplasmic reticulum, or are made from parts of the cell membrane by endocytosis. Vesicles can also fuse with the cell membrane and release their contents to the outside. This process is called exocytosis. In addition to the Golgi apparatus and ER, vesicles can also fuse with other organelles within the cell. Q: What is a small, spherical compartment separated by at least one lipid layer from the cytosol? Choices: - capillary - cuticle - cortex - vesicle A:
vesicle

Answer the following question given this paragraph: Other protists have what are called transient pseudopodia , which are like temporary feet. The cell surface extends out to form feet-like structures that propel the cell forward. An example of a protist with pseudopodia is the amoeba. Q: What are temporary feet that protists have called? Choices: - pedicules - spontaneous pseudopodia - temporary flagella - transient pseudopodia A:
(Answer)
transient pseudopodia
Ques: Answer the following question given this paragraph: Astronomers use many tools to study things in space. Earth-orbiting telescopes view stars and galaxies from the darkness of space ( Figure below ). They may have optical and radio telescopes to see things that the human eye can't see. Spacecraft travel great distances to send back information on faraway places. Q: What type of scientist uses earth-orbiting telescopes? Choices: - astrologer - biologist - anthropologist - astronomer A:
Ans: astronomer

Answer the following question given this paragraph: Solid-state radiation detectors convert ionization produced in a semiconductor (like those found in computer chips) directly into an electrical signal. Semiconductors can be constructed that do not conduct current in one particular direction. When a voltage is applied in that direction, current flows only when ionization is produced by radiation, similar to what happens in a Geiger tube. Further, the amount of current in a solid-state detector is closely related to the energy deposited and, since the detector is solid, it can have a high efficiency (since ionizing radiation is stopped in a shorter distance in solids fewer particles escape detection). As with scintillators, very sophisticated information can be obtained from solid-state detectors. PhET Explorations: Radioactive Dating Game Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating to work. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object. Q: Solid-state radiation detectors convert ionization produced in a semiconductor (like those found in computer chips) directly into what? Choices: - thermal energy - microwaves - isotopes - electrical signal A:
(A).
electrical signal
Ques:Answer the following question given this paragraph: Head hair protects the scalp from ultraviolet light exposure and loss of body heat. Hair in eyelashes, eyebrows, and nostrils traps water, dust, and other irritants. Nails protect the ends of fingers and toes and enhance the sense of touch. Q: What protects the scalp from ultraviolet light exposure and loss of body heat? Choices: - ground hair - temporal hair - receding hair - head hair A:

Ans:head hair
Ques:Answer the following question given this paragraph: A desmosome is a cell junction specialized for cell-to-cell adhesion. They are found in simple and stratified squamous epithelium, and in muscle tissue where they bind muscle cells to one another. These junctions are composed of complexes of cell surface adhesion proteins and linking proteins. These proteins have both an intracellular and extracellular region. Inside the cell, they attach to intracellular filaments of the cytoskeleton. Outside the cell, they attach to other adhesion proteins. Q: Where are the desmosome found in a cell? Choices: - epithelial - neuron - coating - epithelium A:

Ans:
epithelium
