21. This table classifies organisms into one of three domains. What is the
basis of this classification system?
Your answer
Answer: The table shows 3 domain Bacteria , Archae and Eukarya on the basis of the difference in sequence of nucleotide in the rRNA and cells lipid structure and its sensitivity towards antibiotics.
Explanation:
The three domain system was given by Woese and others. They classified the organism into three domain based on the sequence of the nucleotides in the ribosomal RNA and lipid structure (cell membrane) and its sensitivity towards antibiotics.
rRNA was useful for classification because they carry out the same function and its structure has a very little change over the period of time. So, by studying the dissimilarities and similarities in the rRNA we can compare how closely related the species are.
The lipid cell structure(some might contain peptidoglycan others might not) of these three domains are different and their sensitivity towards antibiotics are also different so, these characters combinely helps in classification system.
7. _______________ plant growth increases the length of shoots and roots, while _______________ growth results in an increased girth as layers of woody tissue are laid down.
Answer:
Primary plant growth increases the length of shoots and roots, while secondary growth results in an increased girth as layers of woody tissue are laid down.
Explanation:
Primary growth is as a result of rapid cell division in the shoot apical and root apical meristem. Primary growth leads to an increase in the length of the shoot and the root.
Secondary growth is as a result of cell division in the lateral meristems (vascular cambium and the cork cambium) thereby making the root and stem thick. Secondary growth leads to an increase in thickness or girth of the plant as layers of woody tissue are laid down.

Inbreeding can cause physical defects because _____________ are passed on to the next generation.
a.
DDT
c.
PCBs
b.
estrogen
d.
deleterious recessive genes
Answer:
d. deleterious recessive genes
Explanation:
Inbreeding occurs when offsprings result from two individuals who have a similar genetic sequence because they are closely related. The offsprings borne are prone to be defective because of the similarity between their parents' genes. Inbreeding depression also occurs because the offsprings are not physically fit and can easily succumb to death.
The opposite of inbreeding is crossbreeding which prevents the negative traits that are associated with inbreeding.

Describe the general flow of energy through an ecosystem beginning with the Sun and going through a third order consumer.
Answer:
1) Autotrophs transform solar energy into chemical energy.
2) Herbivores and omnivores (primary consumers) eat producers, make use of some of the energy, making from it their biomass.
3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy.
4) Decomposers (last order in the chain) recycle all the dead organic material and make use of some of the stored energy.
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.
From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.
Organisms that can use light, and turn it into organic matter according to their own needs are producers, and they are called autotrophic organisms. These organisms are by excellence all plants, algae, and bacteria that photosynthesize. Organisms that are incapable of producing their food are called heterotrophic. They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy. In the trophic web, heterotrophic organisms occupy the first, second, or third consumer level, after producers. There are different types of heterotrophic animals: carnivorous, herbivorous, omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.
At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.
The progressive reduction of energy determines the number of trophic levels in the chain (4 or 5).
1) Autotrophs use water, CO2, and solar energy to produce O2 and glucose, by the process of photosynthesis and convert it into biomass. Producers transform solar energy into chemical energy.
2) Herbivores and omnivores (primary consumers) make use of some of this energy to survive, making from it their biomass. The rest of the energy is lost.
3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy. The rest of the energy is lost.
4) When different organisms die, decomposers (last order in the chain) recycle all the organic material and make use of some of the energy stored in their tissues. The rest is lost.

Which amino acid sequence is coded for by the mRNA segment AUG-CCC-CAC-GAA-UAC?
The amino acid sequence that is coded for by the mRNA segment AUG-CCC-CAC-GAA-UAC is: Methionine-Proline-Histidine-Glutamic acid-Tyrosine.
What is amino acid sequence?In the process of protein synthesis, mRNA carries the genetic information from DNA to the ribosome, where it is translated into a protein. The sequence of nucleotides in the mRNA is read in groups of three, known as codons, which code for a specific amino acid. The amino acids are then joined together to form a protein.
In this case, the mRNA segment AUG-CCC-CAC-GAA-UAC corresponds to the codons AUG, CCC, CAC, GAA, and UAC, which code for the amino acids Methionine, Proline, Histidine, Glutamic acid, and Tyrosine, respectively. These five amino acids are joined together to form a specific sequence, which determines the structure and function of the resulting protein

Why does blue light cause a negative photosynthesis rate? (If algae is grown under blue light, why is the rate of photosynthesis slower than other colors?)
Blue photons drive the photosynthetic reaction, although from an energy standpoint, one might consider them less efficient than green or red photons because their high energy isn't fully utilized; some of the energy is essentially lost compared to photosynthetic photons with a longer (less energetic) wavelength.
Which of the biochemical processes do yeast perform in order to obtain energy that their cells can use to do work?
Answer:
Fermentation
Explanation:
Fermentation is a catabolic, anaerobic process, which is not usually accompanied by electronic transport and whose final product is an organic compound. Yeasts are unicellular bodies (generally spherical in shape) with a size of around 2 to 4 μm and that are naturally present in some products such as fruits, cereals and vegetables. They are what are called: facultative anaerobic organisms, that is, they can develop their biological functions without oxygen. Yeasts carry out alcoholic fermentation. Its biological purpose is to provide anaerobic energy to unicellular microorganisms (yeasts) in the absence of oxygen, to dissociate glucose molecules and obtain the energy necessary to survive, producing alcohol and CO2 as fermentation waste.

Answer:
Compression is a reverse fault, tension is normal fault and shear is strike slip fault.
Explanation:
Compression is a reverse fault, tension is normal fault and shear is strike slip fault. Reverse fault is opposite of normal fault which occurs due to the stress of compression on an object in which both object come close together. Due to tension stress, rocks pulling apart from each other, produces a normal fault. Shear is strike slip fault because in strike-slip fault, the two blocks slide over one another
