Answer the following question given this paragraph: Plants are multicellular eukaryotes that are placed in the Plant Kingdom . Plant cells have cell walls that are made of cellulose. Plant cells also have chloroplasts. They allow plants to make food by photosynthesis. In addition, plants have specialized reproductive organs that produce gametes. Male reproductive organs produce sperm. Female reproductive organs produce eggs. Male and female reproductive organs may be on the same plant or on different plants. Q: Plant cells have cell walls that are made of what? Choices: - carbonate - nucleus - tissue - cellulose A:
cellulose

Answer the following question given this paragraph: Photosynthesis takes place in the organelle of the plant cell known as the chloroplasts. Chloroplasts are one of the main differences between plant and animal cells. Animal cells do not have chloroplasts, so they cannot photosynthesize. Photosynthesis occurs in two stages. During the first stage, the energy from sunlight is absorbed by the chloroplast. Water is used, and oxygen is produced during this part of the process. During the second stage, carbon dioxide is used, and glucose is produced. Q: What takes place in the organelle known as the chloroplast, which distinguishes animal from plant cells? Choices: - digestion - reproduction - perspiration - photosynthesis A:
(Answer)
photosynthesis
Ques: Answer the following question given this paragraph: The reverse reaction (amide hydrolysis) is very useful in the study of protein structure. Proteins are long chains of amino acids (each amino acid contains an amine group and a carboxyl group, both attached to a central carbon atom). The amino acids are linked together by amide bonds to form the long protein chain. One of the techniques for looking at protein structure is to break those amide linkages so we can learn the identity of the amino acids in the chain. We do this through a hydrolysis reaction:. Q: What are long chains of amino acids? Choices: - lipids - Fatty Acid Chains - cells - proteins A:
Ans: proteins
(Q).
Answer the following question given this paragraph: Reproduction of Green Algae Green algae reproduce both asexually, by fragmentation or dispersal of spores, or sexually, by producing gametes that fuse during fertilization. In a single-celled organism such as Chlamydomonas, there is no mitosis after fertilization. In the multicellular Ulva, a sporophyte grows by mitosis after fertilization. Both Chlamydomonas and Ulva produce flagellated gametes. Q: In a single-celled organism such as chlamydomonas, there is no what after fertilization? Choices: - germination - spawning - meiosis - mitosis A:
(A).
mitosis
Ques:Answer the following question given this paragraph: The uterus is a hollow organ with muscular walls. The part that connects the vagina with the uterus is called the cervix . The uterus is where a baby develops until birth. The walls of the uterus grow bigger as the baby grows. The muscular walls of the uterus push the baby out during birth. Q: What is the name of the part that connects the vagina with the uterus? Choices: - urethra - ovary - vulva - cervix A:

Ans:cervix
Answer the following question given this paragraph: Freshwater biomes are defined by their low salt concentration, usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration, such as the ocean. There are different types of freshwater biomes: ponds and lakes ( Figure below ), streams and rivers, and wetlands. Ponds and lakes range in size from just a few square meters to thousands of square kilometers. Streams and rivers are bodies of flowing water moving in one direction. They can be found everywhere. They get their starts at headwaters , which may be springs, melting snow, or even lakes, and then travel all the way to their mouths , emptying into another water channel or the ocean. Wetlands are areas of standing water that support aquatic plants. Wetlands include marshes, swamps, and bogs. Q: What are fresh water biomes defined by? Choices: - high salt content - moving water - animal species - low salt concentration A:
low salt concentration
