Why do different types of cells have different lifespans?
Answer:
One reason cells age is because every time they divide, they lose a little bit of DNA from the ends of their chromosomes. This eventually leads to a loss of important DNA, and they die. The solution to this problem is the telomere.
Explanation:
Different types of cells have different lifespans because it depends on the differences in the cellular metabolic rate of the body.
What is a cell?A cell may be defined as the basic structural and functional unit of life in living organisms. It controls and coordinates all the processes which are required for the proper development and maintenance of the body.
One reason behind the unequal life span of the cell is that cells undergo division multiple times in their life, where they lose a little bit of DNA from the ends of their chromosomes.
Ultimately this leads to complete loss of DNA and other factors and eventually, death occurs.
It may be estimated that neutrophil cells might last for only two days, while the cells in the middle of your eye lenses will last for your entire life.
Therefore, it is well described above.

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
List 10-15 Facts About the Vaquita.
Answer:
1 The vaquita, Phocoena sinus, is the world’s smallest cetacean, weighing around 55 kilos.
2 Females grow to be around 1.5 metres long. They are longer than the males, whose length tops out at about 1.4 metres.
3 They eat small fish and squid.
4 They have unique facial markings with a black ring around each eye and curved, black lips that make them look as if they are smiling.
5 Their dorsal surface is dark grey, their sides pale grey, and their underside is white with light grey markings. Newborn calves are darker.
6 Vaquita have proportionally large dorsal fins, possibly as an adaptation to warmer water to allow heat to dissipate.
7 Like other porpoises, vaquitas use sonar to communicate and navigate.
8 Vaquitas are very rarely seen. When they are spotted, they are either alone or in small groups of two or three. They are thus thought to be quite solitary animals.
9 Researchers estimate that vaquita live for around 20 years.
10.They feast on fish, prawns and crabs but are known to have particular preference for squid.
11. Unlike dolphins that will follow boats, vaquitas are shy, private creatures and as such very little is known about them. In fact, these little sea creatures were not discovered until as late as 1958 when three vaquita skulls were discovered on a beach.
12.Although they tend to spend their time in the shallow waters of the coast line or in the open sea no more than 25km (16 mi) from shore, they are so timid that it is very lucky spot a vaquita. The closest sighting has been from a far distance of 300ft [90m].
13.Since they are elusive, not much is known about the social behaviour or the reproductive cycle of the vaquita. Sightings have reported small groups of 2-4, larger groups of up to 10 and even solitary vaquitas.
14.Vaquitas can communicate with each other and navigate using sonar.
15.Sadly, the vaquita is classified as critically endangered with less than 100 thought to survive.

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.

describe the effects of varying frequencies/ wavelengths
Answer:
When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases. The opposite is also true— as frequency decreases, wavelength increases.
Explanation:
The number of complete wavelengths in a given unit of time is called frequency. As a wavelength increases in size, its frequency and energy decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

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.3. During the Krebs Cycle, high-
energy electrons and hydrogen
ions are transferred to carrier
molecules to form NADH and
FADH2. What are the two other
molecules released during the
Krebs Cycle?
Answer:
ATP and Carbon
Explanation:
Carbon is released and so is ATP.
Krebs cycle is also known as Citric acid cycle. It is a process involved in cellular respiration which produces ATP in the cell. The pyruvate formed in the glycolysis undergoes catabolic reactions to produce ATP and other two carbon compounds.
What is Krebs cycle?The Krebs Cycle is also known as the citric acid cycle, which is the second major step in oxidative phosphorylation. During glycolysis, glucose a 6-carbon compound breaks into smaller 3-carbon molecules Pyruvate. The citric acid cycle transfers energy from pyruvate molecules to electron carriers, which will be later used in the electron transport chain to produce ATP.
During the Krebs cycle, pyruvic acid from glycolysis is used to make carbon dioxide, NADH, ATP, and FADH₂. Citric acid is broken down into a 5-carbon compound, which is further converted into a 4-carbon com- pound. Along this way, two more molecules of CO₂ are released, and electrons join to NAD⁺ and FAD, to form NADH and FADH₂.
