in parallel
Answer the following question given this paragraph: The specific heat capacity (c) of a substance, commonly called its "specific heat," is the quantity of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius (or 1 kelvin): q c= mT Specific heat capacity depends only on the kind of substance absorbing or releasing heat. It is an intensive propertythe type, but not the amount, of the substance is all that matters. For example, the small cast iron frying pan has a mass of 808 g. The specific heat of iron (the material used to make the pan) is therefore: c iron =. Q: What is the term for the quantity of heat required to raise the temperature of 1 gram of a substance by 1 degree celsius? Choices: - thermal heat capacity - transferable heat - heat requirement - specific heat capacity A:
specific heat capacity
Q: Answer the following question given this paragraph: The geologic time scale is divided into eons, eras, periods, and epochs. Q: The geologic time scale is divided into eons, eras, periods, and? Choices: - cultures - tropics - zones - epochs A:
A: epochs
Question: Answer the following question given this paragraph: Each pollen grain has two coverings: the exine (thicker, outer layer) and the intine (Figure 32.7). The exine contains sporopollenin, a complex waterproofing substance supplied by the tapetal cells. Sporopollenin allows the pollen to survive under unfavorable conditions and to be carried by wind, water, or biological agents without undergoing damage. Female Gametophyte (The Embryo Sac) While the details may vary between species, the overall development of the female gametophyte has two distinct phases. First, in the process of megasporogenesis, a single cell in the diploid megasporangiuman area of tissue in the ovulesundergoes meiosis to produce four megaspores, only one of which survives. During the second phase, megagametogenesis, the surviving haploid megaspore undergoes mitosis to produce an eight-nucleate, seven-cell female gametophyte, also known as the megagametophyte or embryo sac. Two of the nucleithe polar nucleimove to the equator and fuse, forming a single, diploid central cell. This central cell later fuses with a sperm to form the triploid endosperm. Three nuclei position themselves on the end of the embryo sac opposite the micropyle and develop into the antipodal cells, which later degenerate. The nucleus closest to the micropyle becomes the female gamete, or egg cell, and the two adjacent nuclei develop into synergid cells (Figure 32.8). The synergids help guide the pollen tube for successful fertilization, after which they disintegrate. Once fertilization is complete, the resulting diploid zygote develops into the embryo, and the fertilized ovule forms the other tissues of the seed. Q: Each pollen grain has two coverings: the exine (thicker, outer layer) and the what? Choices: - tube nucleus - pollen tube - cytoplasm - intine A:
Answer: intine

Answer the following question given this paragraph: People have long known that offspring are similar to their parents. Whether it's puppies or people, offspring and parents usually share many traits. However, before Gregor Mendel's research, people didn't know how parents pass traits to their offspring. Q: Whether it's puppies or people, offspring and parents usually share many of what? Choices: - clothes - insects - fruits - traits A:
**Answer**
traits

Answer the following question given this paragraph: The hypothalamus is actually part of the brain (see Figure below ), but it also secretes hormones. Some of its hormones that "tell" the pituitary gland to either secrete or stop secreting its hormones. In this way, the hypothalamus provides a link between the nervous and endocrine systems. The hypothalamus also produces hormones that directly regulate body processes. These hormones travel to the pituitary gland, which stores them until they are needed. The hormones include antidiuretic hormone and oxytocin. Q: What organ is the hypothalamus a part of? Choices: - Nervous system - liver - heart - brain A:
**Answer**
brain
