1. Compare and contrast ATP and NADH.
Answer:
Glycolysis produces 4 ATP molecules, giving it a net gain of 2 ATP molecules. The four high energy electrons that are removed by glycolysis are picked by an electron carrier called NAD. NAD becomes NADH.As it spins it grabs an ADP molecule and attaches a phosphate, forming high energy ATP.
Explanation:
Both NADPH and ATP are phosphorylated compounds, both are very important catabolic as well as anabolic processes. To explain the difference, their respective functions/roles in biochemical processes should be described along with relevant chemical properties.
ATP (Adenosine triphospahte) is called an energy rich molecule because of the large negative free energy of its hydrolysis (And has nothing to do with high bond energy).
30.5 kilo Joules or 7.3 kilo calorie energy is liberated after hydrolysis of one ATP molecule to form ADP (Adenosine diphosphate) and phosphate.The reaction is almost irreversible

How are the cells at the end of meiosis different from the cells at the beginning of meiosis?
Answer:
The cells that enter meiosis II are the ones made in meiosis I. These cells are haploid—have just one chromosome from each homologue pair—but their chromosomes still consist of two sister chromatids. In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes.

What is the relationship between undisturbed sedimentary rock layers and fossils?
Fossils only can be found in the youngest sedimentary rock layers.
Older fossils are found in deeper layers of sedimentary rock.
More recent fossils are found in the deepest of the rock layers.
Answer:
Older fossils are found in deeper layers of sedimentary rock.
Explanation:
The relationship between undisturbed sedimentary rock layers and fossils is that older fossils are found in deeper layers of sedimentary rocks.
This is one of the premise of the law of superposition and principle of fossil and fauna succession.
An undisturbed sequence is one in which the sedimentary layers have been arranged sequentially. The oldest is at the bottom and the youngest on top. Also, fossils grade in this manner too. The oldest fossils will be in the oldest bed which is the deepest layer. The youngest bed will contain the youngest fossils in like manner too.The muscular system helps with ____ and the skeletal system helps with ____. Question 1 options: movement; oxygen exchange movement; structure structure; movement oxygen exchange; structure
Answer:
The correct answer is movement; structure.
The muscular system helps with movement and the skeletal system helps with structure.
Explanation:
The human muscular system constitutes 40% of the total weight of our body and is made up of three types of muscles, which, together with different tendons and thanks to their contraction capacities, allow us to move. The muscular system and the function of the muscles allow the movement of our body and it is the one that works in tune with other systems of our body to guarantee normal general functioning..The skeletal system is the set of organs that support, shape, structure and protect the body. The skeleton is a dynamic structure, specifically the axial skeleton, it is to serve as a support or as a scaffold that supports the organs and structures of the body. This is how bones together with muscles work as a team to allow the mobility of the human body.

For each pair of terms, explain how the meanings of the terms differ. 6. Understory and canopy 7. Latitude and altitude 8. Chaparral and desert 9. Tropical rain forest and temperate deciduous forest
Answer and Explanation:
Understory: vegetation, mainly herbs, bushes, and shrubs, that grow under the trees in a forest. It is the lowest stratum in a forest, nearest the floor, and under the canopy. Young small trees migh also be found in the understory, among the other plants. Limited solar radiation reaches this stratum. It also characterizes by its high humidity level. Canopy: Refers to the areal part of a tree occupied by the branches and foliage. This area might be projected ground to study its size and the area occupied by them. In general, the canopy interrupts the pass of light to the ground, shading it. Under the canopy there is a special environment where smaller plants might grow, composing the understory vegetation. Latitude: Refers to the distance, measured in degrees, from the equator to the north or to the south. Altitude: Refers to the distance from the sea level to the top of a certain place or object. Chaparral: Biome that characterizes for precipitations between 250-1000 mm. and temperature between 10-20ºC. The dry season occurs during the summer, while the wet season occurs in winter. The dry season is very hard due to the elevated temperatures. Fanerophits dominate the vegetation. There are low forests, with sclerophyllous shrubs and trees.Desert: This is the hottest biome in the world, characterized by very limited precipitations that oscillate between 0-500 mm. and elevated temperatures. There is a hydric deficit almost the whole year. There are different kinds of deserts according to the temperature and the precipitation degree. Different species are adapted to live in this environment, such as cryptophytes, pterophytes, and deciduous phanerophytes. All of them avoid dehydration by developing different strategies. Succulents, sclerophytes, and phreatophytes resist elevated temperature and lack of water. Tropical rain forest: The tropical rainforest as a biome is located in areas near the equator, where precipitations are abundant and the average temperature is elevated most of the year. As a result of the climatic conditions, this biome gives shelter to a huge number of living organisms. Also, the canopy structure provides many refuges for plants and animals and is an important source of food. It also favors interactions between species. There are too many species in the rainforest that have not been discovered. Temperate deciduous forest: Template forest biome characterizes for having deciduous trees such as oaks, maple, or olms, among other phanerophyte species. These plant species lose their leaves every year during the cold and dry autumns and winters, as it is the most limiting period over the year. Foliage resprout again during the warmer wet season when it rains more often, during spring and summer. These forests are located between 30º and 60º latitude in both hemispheres. Precipitations might be over 1000mm. Soils are very fertile and deep, due to the leaves´ loss that provides nutrients to the soil and protects it from erosion.16.

PLS HELP DOES ANYONE KNOW OR REMEBER THE ANSWER TO THIS QUESTION ILL GIVE 40 POINTS
Answer:
The correct answer is - option 3. Energy for life processes can be stored within the chemical bonds of both molecules.
Explanation:
Sugar molecule and fat molecule both are organic molecules and use as nutrients that are made up of respective atoms or monomers. Sugar molecules are made up of monosaccharides by linking together with bonds. Similarly in fat molecules, are made up of glycerol backbone and fatty acids.
The bonds present in these molecules store the energy and by breaking the bonds they release a high amount of energy. The bonds present in fats release more energy than sugar molecules.
The covalent bonds including both components potentially absorb excess for biological activities.
Sugar, as well as fat compounds, would both be chemical compounds that are used as nourishment and therefore are mainly composed of individual atoms.Monosaccharides are already joined together across connections to form glucose molecules. Likewise, adipose molecules are formed of something like a glycerol framework as well as unsaturated fats.
Thus the above approach i.e., "option 3" is right.
