If a drug was administered that would impede the binding of NAD+ to electrons what steps of cellular respiration would this substance affect
Answer:
The correct answer is - not getting all NAD+ so burning more ATP to make up for the energy loss.
Explanation:
If the drug was administered and it would cause impedetion of the binding of NAD+ to electrons which causes decrease availability of the NAD+ that leads to less energy formation due to the use up more ATPs in the process of cellular respiration.
If NADH couldn't be formed as NAD+ will not binding, the cells will lose out on ATP produced. It will lead to weight loss due to burning out more ATP to make up for the energy loss.
How are Photosynthesis and Cellular Respiration Cycles connected?
1)The products of one cycle become the reactants of the other.
2)The sun provides energy for both photosynthesis and respiration.
3)Photosynthesis and respiration both take place in the mitochondria.
4)Animals eat plants for food and then do not need to perform respiration

Does every gene combination show up in the offspring?
Answer:
Answer!
Explanation:
Okay so, genes come in different varieties; which are called allele. somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. BUT, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
During meiosis I, chromosomal pairs randomly align along the metaphase plate. Each chromosome pair member carries one allele for each gene. Every gene combination shows up in the offspring.
Chance determines which of the 23 homologous pairs of both parents' chromosomes are inherited. The possible combinations of 23 chromosomal pairs total 8,324,608. As a result, the chromosomal combinations of two gametes are almost never identical.
Actually, each parent has two distinct gene pools. Additionally, only half of each parent's DNA is passed on to their offspring. and that the randomness of the portion that is passed down. All of these factors work together to guarantee that every child has a distinct collection of genes.

What type of plants commonly grows in the lower biomes of a mountain? (1 Punto)
Answer:
Alpines, Mosses, Lichens etc
Explanation:
These type of plants survive in very harsh conditions in which the mountain regions are associated with.
The conditions include a higher degree of temperature, little or no amount of soil particles, dryness and a very low degree of nutrients available to them which makes their growth usually stunted when compared to plants in other regions.
The three main constituent minerals of granite stones are feldspar, mica, and quartz. The textures of different types of
granite stones are shown in the picture.
Based on the textures, it can be said that
A)
the proportion of mica in all the forms of granite is fixed.
B)
the proportion of quartz in all the forms of granite is fixed.
the three minerals vary in proportion in each form of granite.
D)
the three minerals are in the same proportion in each form of granite.
Answer:
Option C
Explanation:
Granite is composed of coarse-grained quartz and feldspars in varying proportions and due to the varying proportions of these two constituent materials, the texture of granite varies as shown in the image.
Thus, option C is correct
Options A and B and D are incorrect because the constituent material of granite is not fixed. It varies from from place to the other.
The power in our homes and buildings cycles at a frequency of 60Hz. If someone accidentally dropped a power line into a holding tank for frogs their muscles would immediately become stiff. This is because the high frequency stimuli is causing:_______
a. rigor mortis.
b. tetanus.
c. fatigue.
Answer:
a. rigor mortis.
Explanation:
Electricity refers to the power generated from various power sources or power plants such as hydroelectric, wind turbine, solar, nuclear, etc.
Generally, the power supplied to homes, offices and buildings cycles at a frequency of 60 Hertz or 50 Hertz depending on the parameters chosen in countries. If a power line is dropped accidentally into a holding tank for frogs, it would immediately cause their muscles to become stiff due to the current flowing through the power line i.e because the power line is energized and has electrons moving across its terminals. This stiffness is because the high frequency stimuli is causing rigor mortis.

Explanation:
the potential for antibiotic resistance was recognized in the early 1940s, almost immediately after the first large-scale clinical use of penicillin, the first antibiotic. mass production of penicillin was part of the war effort of world war ii, when the drug was used widely by military populations to treat the wounded. however, even before the war had ended, resistance to penicillin was already being reported. in 1940, british biochemists sir ernst boris chain and sir edward penley abraham published a report about a bacterial enzyme capable of destroying penicillin. in the following decades, overuse and repeated exposure to antibiotic agents favored the selection and replication of numerous strains of antibiotic-resistant bacteria. select all of the statements that accurately portray the role of natural selection in antibiotic resistance. a) when bacteria are repeatedly exposed to antibiotics, they learn how to avoid the antibiotic and survive to reproduce. b) when people overuse antibiotics, the bacteria get resistant to the antibiotic and it is no longer an effective treatment. some bacteria possess a gene for bacterial resistance. these bacteria are likely to survive a course or antibiotics and reproduce. 09 d) bacteria containing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce. when someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. the bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce. e
Answer: c,d,e
Explanation:
I did this and this is correct
Answer:
The following Statements accurately portrays role of natural selection in antibiotic resistance
c) some bacteria possess a gene for bacterial resistance. these bacteria are likely to survive a course or antibiotics and reproduce.
d) bacteria containing the gene for antibiotic resistance can share a plasmid of the gene with other bacteria, allowing the population of bacteria with antibiotic resistance to survive and reproduce
e) when someone quits taking an antibiotic when they are feeling better, they likely kill only the weaker bacteria. the bacteria with a gene for antibiotic resistance survive, giving them the opportunity to reproduce
Explanation:
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features to succeeding generations.
As in option C , bacteria possessing better gene will b selected by the nature and hence portrays Natural selection
In option d Bacteria reproduce by plasmid (extra chromosomal DNA ) transfer . Bacteria with antibiotic resistant gene with pass these genes to the succeeding generations.
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving bacteria possessing gene resistant against antibiotics. Here, Darwin’s theory of natural selection comes in. This gives the bacteria an advantage over other(which do not possess antibiotic resistant gene) this bacteria will grow better than its neighbors and can increase in numbers
In option e When one quits antibiotics before completing the entire course of any prescribed antibiotic. The antibiotic resistant bacteria survives. Bacteria that are not controlled or killed by antibiotics. They are able to survive and even multiply in the presence of an antibiotic.

Explanation:
because that is the 2nd decompers
B group would represent the decomposer organisms. Therefore, the correct option is B.
What are Decomposers?Decomposers are organisms that convert decaying organic matter into more basic components. They are an important component of the nutrition cycle because they convert complex chemical substances, such as nitrogen and carbon, into direct nutrients that can be absorbed by plants and other living things.
Some species of bacteria, fungi and insects are specialized decomposers. These organisms are essential to maintaining healthy soil because they aid in the recycling of nutrients and the breakdown of organic matter, which would otherwise build up and cause nutrient imbalances. Decomposers, which break down dead organisms and aid in the containment of pathogens, may be important in disease prevention.
Therefore, the correct option is B.
