The doubling time of a bacterium was measured at two different temperatures. Which results would be expected of a thermophile
Answer:
Increase in high temperature.
Explanation:
The population of the thermophile bacteria increase at high temperature as compared to other bacteria at high temperature because thermophile bacteria needs high temperature for growth and survival. Thermophile bacteria that flourish at relatively high temperatures ranging from 41 to 122 °C (106 and 252 °F) so we can conclude that the thermophile bacteria increase in population in the high temperature conditions.

It is impossible for sperm to be functional (able to fertilize the egg) until after ________. Group of answer choices
Answer:
The answer is "they undergo capacitation"
Explanation:
Sperm migrate through uterine contractions and the energies of its flagella to the uterine tube. In sperm motility, reverse peristalsis is engaged in the uterus and uterine tubes. For a sperm cell to fertilize an egg, it takes approximately 24 hours. The surface of the egg changes as the sperm penetrates the egg, therefore no sperm is allowed within. The kid is fully genetic, including whether it's a boy or a girl at the time of fertilization. Until they are trained it is difficult for sperm to be working.
How can a scientist determine if two species are obligate mutualists? The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then add an invading species to see if it outperforms one of the other species. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then transplant both species to a new location to observe if they do better or worse than the individuals in their old location. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then remove one of the species to see if the other species does not survive.
Answer:
The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die
Explanation:
When two species are obligate mutualists, both species benefit one another in such a way that one cannot survive without the other. Hence, in order to find out if two species are indeed obligate mutualists, they should be transplanted together away from other species on one side, and also transplanted individually on another side.
If they are obligate mutualists, the individual transplant would find it difficult to survive and should die in no time while the transplant done together should survive. All other factors being kept constant.

Answer:
a. The hog farmer does not notice the barn smell from the working boots when he wears them on the porch of the house.
Explanation:
The hog farmer does not notice the barn smell from the working boots when he wears them on the porch of the house is the example of sensory adaptations. Sensory adaptation is a decrease in sensitivity to a stimulus after regular exposure to it. So the farmer can't smell his own boots due to regular exposure to the smell so we can say that it is an example of sensory adaptations..

During the process of genetic recombination, crossing over occurs between two nonsister chromatids. DNA segments are exchanged between two nonsister chromatids during meiosis I. None of the above. maternal and paternal chromosomes pair and physically exchange DNA segments. All of the above.
Answer:
DNA segments are exchanged between two non-sister chromatids during meiosis I.
Explanation:
An exchange of chromosome segments or parts between non-sister homologous chromatids occurs which is also called crossing over. This crossing over occurs in the meiosis I that is responsible for the variation in the offspring produced. The formation of hybrid species occurs due to this exchanged of DNA segments between two non-sister chromatids.

A man with Type B blood has children with a woman with type A blood. Their children have the following blood types, A, AB, B, and O. What are the genotypes of the parents? What would be the genotypes of the parents if the offspring could only have type AB or A blood
the child has the blood type of Ab its obvious
Explanation:
only when both alleles is O, the blood group can be O. Thus both parents must have O as one allele
Thus man's genotype: BO or
[tex] { | }^{b} i[/tex]
Woman's genotype : AO or
[tex] { | }^{a} i[/tex]
When
the children can not have O blood
The children cannot have B blood
means the man have BO
[tex] { | }^{b} i[/tex]
and woman have AA
[tex] { | }^{a} { | }^{a} [/tex]
Because
if man have BB, and woman have AA
children can only have AB
if man have BB, and woman have AO
children can only have AB and B

Which statement best describes the step in muscle contraction when the sarcomere is the shortest?
A The sarcomere is contracted, and the actin and myosin filaments are partially overlapped.
B The sarcomere is relaxed, and the actin and myosin filaments are partially overlapped.
C The sarcomere is contracted, and the actin and myosin filaments are completely overlapped.
D The sarcomere is relaxed, and the actin and myosin filaments are completely overlapped.
Answer:
C The sarcomere is contracted, and the actin and myosin filaments are completely overlapped.
Explanation:
In rest, the tropomyosin inhibits the attraction strengths between myosin and actin filaments. Contraction initiates when an action potential depolarizes the inner portion of the muscle fiber. Calcium channels activate in the T tubules membrane, releasing calcium into the sarcolemma. At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to troponin C, troponin T alters the tropomyosin position by moving it and unblocking the binding sites. Myosin heads join the uncovered actin-binding points forming cross-bridges, and while doing so, ATP turns into ADP and inorganic phosphate, which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament. Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Finally, Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.
In the sarcomere, which is the contractile unit of skeletal muscles, there are
Thick myosin myofilaments in the central region belonging to the A band. Thin filaments united to the Z lines, extending in the interior of the A band until they reach the border of the H band. Thin actin filaments composing the I band, which belong to two sarcomeres adjacent to a Z line.When the muscle contracts, the muscular fiber gets shorter and thicker due to the reduction in the length of the sarcomere. The H line and the I band get shorter. The Z lines get closer to the A band, meaning that they get closer to each other. A band keeps constant in length. This change is produced by movement mechanisms that involve a change in the relative position of actin and myosin filaments.

Just after they taste a sweet liquid, mice are injected with a drug that produces an immune response. Later, the taste of the sweet liquid by itself triggers an immune response. This best illustrates
Answer:
This question lacks options, options are:
a) classical conditioning
b) observational learning
c) spontaneous recovery
d) operant conditioning.
The correct answer is a.
Explanation:
The classical conditioning theory derives from the experiments of the Russian physiologist Ivan Pavlov, he hypothesized that when any stimulus predicts the occurrence of another stimulus that triggers an automatic response, that first stimulus would acquire the ability to trigger that response, in other words , is a type of learning according to which an originally neutral stimulus, which does not provoke a response, becomes able to provoke it thanks to the associative connection of this stimulus with the stimulus that normally provokes said response. The conditioning of the immune response is built on the same principles of the classical conditioning paradigm described by Ivan P. Pavlov in which an environmental stimulus that by itself does not produce any immune reaction (conditioned stimulus), is associated with substances that stimulate or they suppress immune function (unconditioned stimulus), and finally, by presenting the conditioned stimulus alone, trigger the appropriate immune response.
