Answer the following question given this paragraph: Structure of a Typical Leaf Each leaf typically has a leaf blade called the lamina, which is also the widest part of the leaf. Some leaves are attached to the plant stem by a petiole. Leaves that do not have a petiole and are directly attached to the plant stem are called sessile leaves. Small green appendages usually found at the base of the petiole are known as stipules. Most leaves have a midrib, which travels the length of the leaf and branches to each side to produce veins of vascular tissue. The edge of the leaf is called the margin. Figure 30.21 shows the structure of a typical eudicot leaf. Q: Some leaves are attached to the plant stem by a petiole. leaves that do not have a petiole and are directly attached to the plant stem are called this? Choices: - sheath leaves - globular leaves - transverse leaves - sessile leaves A:
sessile leaves
Answer the following question given this paragraph: A monoprotic acid is an acid that contains only one ionizable hydrogen. Hydrochloric acid and acetic acid are monoprotic acids. A polyprotic acid is an acid that contains multiple ionizable hydrogens. Most common polyprotic acids are either diprotic (such as H 2 SO 4 ) or triprotic (such as H 3 PO 4 ). Q: Which acid contains only one ionizable hydrogen? Choices: - citric acid - lactic acid - amino acid - monoprotic acid A:
monoprotic acid
Q: Answer the following question given this paragraph: Like mitochondria, plastids contain their own DNA. Therefore, according to endosymbiotic theory, plastids may also have evolved from ancient, free-living prokaryotes that invaded larger prokaryotic cells. If so, they allowed early eukaryotes to make food and produce oxygen. Q: Like mitochondria, plastids contain their own what? Choices: - riboflavin - bacteria - molecule - dna A:
A: dna
Question: Answer the following question given this paragraph: Q: Prior to ovulation, ovarian steroid hormones stimulate the uterus to prepare for support of what? Choices: - fertilization - fetus - childbirth - embryo A:

Answer the following question given this paragraph: The human skeleton is an endoskeleton that consists of 206 bones in the adult. It has five main functions: providing support to the body, storing minerals and lipids, producing blood cells, protecting internal organs, and allowing for movement. The skeletal system in vertebrates is divided into the axial skeleton (which consists of the skull, vertebral column, and rib cage), and the appendicular skeleton (which consists of the shoulders, limb bones, the pectoral girdle, and the pelvic girdle). Q: The human skeleton is an endoskeleton that consists of 206 bones in the adult. it has five main functions: providing support to the body, storing minerals and lipids, producing blood cells, protecting internal organs, and this? Choices: - Forward movement - enough movement - more movement - allowing movement A:
**Answer**
allowing movement

Answer the following question given this paragraph: Water on Mars can't be a liquid. This is because the pressure of the atmosphere is too low. The planet does have a lot of water; it is in the form of ice. The south pole of Mars has a very visible ice cap. Scientists also have evidence that there is also a lot of ice just under the Martian surface. The ice melts when volcanoes erupt. At this times liquid water flows across the surface. Q: What form does water take on the planet mars? Choices: - plasma - gas - liquid - ice A:
(A).
ice
