Answer the following question given this paragraph: Q: Karyotyping shows whether what structures, which contain genetic information, are normal in number and appearance? Choices: - neutrons - ribosomes - nucleoids - chromosomes A:
chromosomes
Answer the following question given this paragraph: The epidermis of the leaf consists of a single layer of tightly-packed dermal cells. They secrete waxy cuticle to prevent evaporation of water from the leaf. The epidermis has tiny pores called stomata (singular, stoma) that control transpiration and gas exchange with the air. For photosynthesis, stomata must control the transpiration of water vapor and the exchange of carbon dioxide and oxygen. Stomata are flanked by guard cells that swell or shrink by taking in or losing water through osmosis . When they do, they open or close the stomata (see Figure below ). Q: What type of cells make up the epidermis of a leaf? Choices: - chloroplasts - endothermic cells - mesophyll - dermal cells A:
dermal cells
Q: Answer the following question given this paragraph: Seedless vascular plants have vascular tissue but do not have seeds. Q: What type of plants have vascular tissue but do not have seeds? Choices: - rocky vascular plants - ofen vascular plants - starchy vascular plants - seedless vascular plants A:
A: seedless vascular plants
Question: Answer the following question given this paragraph: Major climate types are based on temperature and precipitation. Latitude plays an important role in determining the climate of a region. However, many other factors play a role in climate. Oceans and mountain ranges influence climate in the same ways worldwide ( Figure below ). You can see where the climate types are on the map, and then read about them below. Q: Latitude plays an important role in determining what in a region? Choices: - drought - landscape - migration - climate A:
Answer: climate

Answer the following question given this paragraph: Role of Endocrine Gland Stimuli Reflexes triggered by both chemical and neural stimuli control endocrine activity. These reflexes may be simple, involving only one hormone response, or they may be more complex and involve many hormones, as is the case with the hypothalamic control of various anterior pituitarycontrolled hormones. Humoral stimuli are changes in blood levels of non-hormone chemicals, such as nutrients or ions, which cause the release or inhibition of a hormone to, in turn, maintain homeostasis. For example, osmoreceptors in the hypothalamus detect changes in blood osmolarity (the concentration of solutes in the blood plasma). If blood osmolarity is too high, meaning that the blood is not dilute enough, osmoreceptors signal the hypothalamus to release ADH. The hormone causes the kidneys to reabsorb more water and reduce the volume of urine produced. This reabsorption causes a reduction of the osmolarity of the blood, diluting the blood to the appropriate level. The regulation of blood glucose is another example. High blood glucose levels cause the release of insulin from the pancreas, which increases glucose uptake by cells and liver storage of glucose as glycogen. An endocrine gland may also secrete a hormone in response to the presence of another hormone produced by a different endocrine gland. Such hormonal stimuli often involve the hypothalamus, which produces releasing and inhibiting hormones that control the secretion of a variety of pituitary hormones. In addition to these chemical signals, hormones can also be released in response to neural stimuli. A common example of neural stimuli is the activation of the fight-or-flight response by the sympathetic nervous system. When an individual perceives danger, sympathetic neurons signal the adrenal glands to secrete norepinephrine and epinephrine. The two. Q: What types of stimuli control endocrine activity? Choices: - light and pressure - temperature and light - pressure and chemical - chemical and neural A:
**Answer**
chemical and neural

Answer the following question given this paragraph: Because the organs of the integumentary system are external to the body, you may think of them as little more than "accessories," like clothing or jewelry. But the organs of the integumentary system serve important biological functions. They provide a protective covering for the body and help the body maintain homeostasis. Q: What provides a protective covering for the body and helps maintain homeostasis? Choices: - unadorned system - endorcrine system - lysogenic system - integumentary system A:
(A).
integumentary system
