Answer the following question given this paragraph: Magnesium (Mg) and calcium (Ca) are also important macronutrients. The role of calcium is twofold: to regulate nutrient transport, and to support many enzyme functions. Magnesium is important to the photosynthetic process. These minerals, along with the micronutrients, which are described below, also contribute to the plant's ionic balance. In addition to macronutrients, organisms require various elements in small amounts. These micronutrients, or trace elements, are present in very small quantities. They include boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni), silicon (Si), and sodium (Na). Deficiencies in any of these nutrientsparticularly the macronutrientscan adversely affect plant growth (Figure 31.4. Depending on the specific nutrient, a lack can cause stunted growth, slow growth, or chlorosis (yellowing of the leaves). Extreme deficiencies may result in leaves showing signs of cell death. Q: What process is magnesium important to? Choices: - dna replication - carbon cycle - absorption - photosynthetic A:
(Answer)
photosynthetic
Ques: Answer the following question given this paragraph: Members of the genus Trypanosoma are flagellate protozoa that cause sleeping sickness , which is common in Africa. They also cause Chagas disease , which is common in South America. The parasites are spread by insect vectors. The vector for Chagas disease is shown in Figure below . Trypanosoma parasites enter a person's blood when the vector bites. Then they spread to other tissues and organs. The diseases may be fatal without medical treatment. Q: Members of the genus trypanosoma are flagellate protozoa that cause what? Choices: - cancer - hypertension - mutations - sleeping sickness A:
Ans: sleeping sickness
(Q).
Answer the following question given this paragraph: An embryo is an organism in the earliest stages of development. Embryos of different species may look quite similar, even when the adult forms look very different. Look at the drawings of embryos in Figure below . They represent very early life stages of a chicken, turtle, pig, and human being. The embryos look so similar that it's hard to tell them apart. Such similarities provide evidence that all four types of animals are related. They help document that evolution has occurred. Q: What is defined as an organism in the earliest stages of development? Choices: - a zygote - a gamete - an nucleus - an embryo A:
(A).
an embryo
