Answer the following question given this paragraph: Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass, which is how much matter the object contains. It also depends on the downward acceleration of the object due to gravity, which is the same all over Earth. Weight can be represented by the equation:. Q: What is the term for the measure of the force of gravity pulling down on an object? Choices: - mass - density - pressure - weight A:
weight
Answer the following question given this paragraph: Cells with different functions often have different shapes. The cells pictured in Figure below are just a few examples of the many different shapes that cells may have. Each type of cell in the figure has a shape that helps it do its job. For example, the job of the nerve cell is to carry messages to other cells. The nerve cell has many long extensions that reach out in all directions, allowing it to pass messages to many other cells at once. Do you see the tail-like projections on the algae cells? Algae live in water, and their tails help them swim. Pollen grains have spikes that help them stick to insects such as bees. How do you think the spikes help the pollen grains do their job? ( Hint: Insects pollinate flowers. ). Q: Different shapes often correlate with different what in cells? Choices: - systems - enzymes - types - functions A:
functions
Q: Answer the following question given this paragraph: Introduction Animal reproduction is necessary for the survival of a species. In the animal kingdom, there are innumerable ways that species reproduce. Asexual reproduction produces genetically identical organisms (clones), whereas in sexual reproduction, the genetic material of two individuals combines to produce offspring that are genetically different from their parents. During sexual reproduction the male gamete (sperm) may be placed inside the female's body for internal fertilization, or the sperm and eggs may be released into the environment for external fertilization. Seahorses, like the one shown in Figure. Q: What kind of reproduction produces genetically identical organisms or clones? Choices: - Prophase I - Meiosis - Sexual - asexual A:
A: asexual
Question: Answer the following question given this paragraph: 19.2 Population Growth and Regulation Populations with unlimited resources grow exponentiallywith an accelerating growth rate. When resources become limiting, populations follow a logistic growth curve in which population size will level off at the carrying capacity. Populations are regulated by a variety of density-dependent and density-independent factors. Life-history characteristics, such as age at first reproduction or numbers of offspring, are characteristics that evolve in populations just as anatomy or behavior can evolve over time. The model of r- and K-selection suggests that characters, and possibly suites of characters, may evolve adaptations to population stability near the carrying capacity (K-selection) or rapid population growth and collapse (r-selection). Species will exhibit adaptations somewhere on a continuum between these two extremes. Q: When resources become limiting, populations follow a logistic growth curve in which the size will level off at a point called what? Choices: - believed capacity - full capacity - containing capacity - carrying capacity A:
Answer: carrying capacity

Answer the following question given this paragraph: Halogens have filled valence electron configurations. Halogens tend to form salts with metals. As the free elements, halogens are monatomic. Halogens have appreciable nonmetallic character. Halogens tend to have an oxidation state of 1. Halogens are good reductants. Q: Halogens tend to form salts with what type of element? Choices: - nonmetals - metalloids - man-made - metals A:
**Answer**
metals
(Q).
Answer the following question given this paragraph: All plants have a characteristic life cycle that includes alternation of generations. Asexual reproduction with spores produces a haploid gametophyte generation. Sexual reproduction with gametes and fertilization produces a diploid sporophyte generation. Q: Alternation of generations is characteristic of the life cycle of all what? Choices: - cells - animals - organs - plants A:
(A).
plants
