Answer the following question given this paragraph: Nutrients the body needs in relatively large amounts are called macronutrients . They include carbohydrates, proteins, lipids, and water. All macronutrients except water can be used by the body for energy. (The energy in food is measured in a unit called a Calorie. ) The exact amount of each macronutrient that an individual needs depends on many factors, including gender and age. Recommended daily intakes by teens of three macronutrients are shown in Table below . Based on your gender and age, how many grams of proteins should you eat each day?. Q: Nutrients the body needs in relatively large amounts are called what? Choices: - vitamins - micronutrients - minerals - macronutrients A:
macronutrients

Answer the following question given this paragraph: From the end of the eighth week until birth, the developing human organism is referred to as a fetus . Birth typically occurs at about 38 weeks after fertilization, so the fetal period generally lasts about 30 weeks. During this time, as outlined in Figure below , the organs complete their development. The fetus also grows rapidly in length and weight. Q: What is the developing human organism referred to as from the end of the eighth week until birth? Choices: - egg - nucleus - babies - fetus A:
(Answer)
fetus
Ques: Answer the following question given this paragraph: Introduction All living organisms need nutrients to survive. While plants can obtain the molecules required for cellular function through the process of photosynthesis, most animals obtain their nutrients by the consumption of other organisms. At the cellular level, the biological molecules necessary for animal function are amino acids, lipid molecules, nucleotides, and simple sugars. However, the food consumed consists of protein, fat, and complex carbohydrates. Animals must convert these macromolecules into the simple molecules required for maintaining cellular functions, such as assembling new molecules, cells, and tissues. The conversion of the food consumed to the nutrients required is a multi-step process involving digestion and absorption. During digestion, food particles are broken down to smaller components, and later, they are absorbed by the body. Q: Plants obtain the molecules for cellular function though what? Choices: - tissues - nutrients - Plants - photosynthesis A:
Ans: photosynthesis

Answer the following question given this paragraph: possess a single, undivided lobe. Eutherian mammals also possess a specialized structure that links the two cerebral hemispheres, called the corpus callosum. Q: Eutherian mammals possess a specialized structure called the corpus callosum that links what hemispheres? Choices: - cortical - appendages - spatial - cerebral A:
(A).
cerebral
Ques:Answer the following question given this paragraph: Structures like the human tail bone are called vestigial structures . Evolution has reduced their size because the structures are no longer used. The human appendix is another example of a vestigial structure. It is a tiny remnant of a once-larger organ. In a distant ancestor, it was needed to digest food. It serves no purpose in humans today. Why do you think structures that are no longer used shrink in size? Why might a full-sized, unused structure reduce an organism's fitness?. Q: What purpose does the appendix serve in humans today? Choices: - work - filters blood - digests food - none A:

Ans:none
Answer the following question given this paragraph: 11.2 Mechanisms of Evolution There are four factors that can change the allele frequencies of a population. Natural selection works by selecting for alleles that confer beneficial traits or behaviors, while selecting against those for deleterious qualities. Mutations introduce new alleles into a population. Genetic drift stems from the chance occurrence that some individuals have more offspring than others and results in changes in allele frequencies that are random in direction. When individuals leave or join the population, allele frequencies can change as a result of gene flow. Q: Out of the four ways that allele frequencies of a population can be changed, which way is caused by individuals leaving or joining the population? Choices: - Allopatric speciation - spontaneous mutation - mass extinction - gene flow A:
gene flow
