Answer:
The true statements regarding the adrenal glands' relationship with the autonomic nervous system are:
a. The adrenal cortex is an extension of the parasympathetic nervous system.
c. The adrenal glands are strictly nerve tissue.
d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.
e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.
Explanation:
The levels of the central nervous system which play important roles in influencing the autonomic nervous system include cerebral cortex, hypothalamus, brain stem, and spinal cord. Usually, epinephrine (adrenaline) and norepinephrine are released into the blood stem when stress or a threat occurs. This alert serves as a warning signal and defense system. The purpose is to maintain homeostasis.
What are the scientific findings that support the view of biological evolution?
Explanation:
Sir/Miss,
Perhaps the most persuasive fossil evidence for evolution is the consistency of the sequence of fossils from early to recent. Nowhere on Earth do we find, for example, mammals in Devonian (the age of fishes) strata, or human fossils coexisting with dinosaur remains.

Explain the benefit of higher myoglobin levels for individuals living at high altitudes
how does this show the relationship between photosynthesis and cellular respiration
Answer:
mark me brainlist
Explanation:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
.
. Imagine the following scenario. A bacteriophage taken for the treatment of cholera infects a cholera-causing bacterium and temporarily enters the lysogenic stage. When the virus re-enters the lytic cycle, it includes some pieces of the bacterial DNA in its own genome. Specifcally, this DNA encodes information for making the cholera toxin. Imagine some of the possible consequences of this scenario. What will happen to the next bacteria that the virus infects
Answer:
The virus will transfer the DNA encoding cholera toxin to the next bacteria it infects, which will make that bacteria cholera-causing.
Explanation:
The process described in this question is a kind of gene transfer in bacteria called TRANSDUCTION. Transduction is the transfer of fragments of DNA from one bacterium to another via a virus called bacteriophage.
As stated in this question, the virus (bacteriophage) infects a cholera-causing bacterium. The bacteriophage moves from lysogenic cycle to lytic cycle and includes some pieces of the bacterial DNA, which encodes information for making the cholera toxin, in its own genome.
This means that the cholera-making toxin DNA is now a part of the virus's genome and hence, will transfer it to the next bacteria it infects in a process called TRANSDUCTION. This will make that bacteria a cholera causing bacteria.

Explanation:
5. Shawn has a hypothesis that fungicides harm bee development. Using what you now know, describe an experiment to test Shawn’s hypothesis. Be sure your response includes what data should be collected and how you would collect it.
Answer:
Yes.
Explanation:
Yes, the fungicides harm bee development by causing changes in behavior, immune health, and reproduction etc. For verifying this hypothesis, we have to take two environments, in one environment fungicides are applied to the plants while on the other environment, there is no fungicide applied to the plants. Th result shows that the bees are affected and act abnormal where fungicides are applied as compared to those bees which are normal in behaviour and other features.

When an organism encounters nitrate in its environment, which condition will determine whether the nitrate is used in an assimilatory or dissimilatory manner?
a. low concentration or ammonia
b. low concentration of sulfate
c. oxygen present
d. low temperature
e. oxygen absent
f. high concentration of nitrite
Answer:
Dissimilatory- oxygen absent
Assimilatory- high concentration of nitrite
Explanation:
In assimilatory nitrate reduction, ammonium is produced and subsequently incorporated into biomass to build up e.g., proteins and nucleic acids. Dissimilatory nitrate reduction is a process for energy conservation, in which nitrate is used as an electron acceptor in the (near) absence of oxygen . Dissimilatory nitrate reduction and nitrate storage in particular are physiological life traits that provide microbes with environmental flexibility (i.e., metabolic activity under both oxic and anoxic conditions) and resource independence (i.e., anaerobic metabolism without immediate nitrate supply), respectively. Such life traits are especially important in environments that are temporarily anoxic and/or nitrate-free and they may have developed as a “life strategy” in both prokaryotes and eukaryotes
Discuss the origin of the Neandertals in terms of biological adaptation and other forces of evolution.
Answer:
Neandertals are closest relative to modern humans as their large brains size had to do with their meat diets. There were many theories including the Allens theory or Bergman theory their larger nasal apertures to cold environments.
Smaller bodies are adapted to more hot climates, and larger bodies are adapted to more cold climates as per Bergman's rule. Allen's rule says that the principle that limbs are longer in hot environments and shorter in cold environments.
Can the use of badger control (including culling) be justified in the
prevention of the spread of bovine tuberculosis (
Answer:
no. badger vaccination is better
Explanation:
spreading mostly happens cattle to cattle
"killing badgers will not solve the problem. Badgers are not the primary cause of the spread of bTB in cattle: the primary route of infection is cattle-to-cattle contact[2]. The Government's badger cull is flying in the face of science. It should be putting more resources into speeding up the development of an effective cattle vaccine, amongst other measures"

Many of the phenotypes of DiGeorge syndrome have been traced back to one of the genes that is in the deleted region, TBX1. Some of the evidence for the important role of TBX1 in DiGeorge syndrome came from individuals who have some of the symptoms of DiGeorge syndrome without having the typical deletion. Closer examination showed that some of these individuals had SNV in the TBX1 gene. Which of the following SNVS would be most likely to create a similar phenotype to the deletion?
A. A variant in the promoter region of TBX1 that increases its expression
B. A variant in the intronic region of TBX1 that does not affect splicing. X
C. A nonsense variant near the 5' end of the TBX1 gene.
D. A silent variant near the 5' end of the TBX1 gene.
Answer:
D. A silent variant near the 5' end of the TBX1 gene.
Explanation:
TBX1 gene is wild type human being. It gives instructions for making protein called T-box 1. It plays an important role in tissue formation and organs during embryonic development.

Given the latitudinal differences in sunlight intensity, how might you expect the carrying capacity of a plant species found at the equator to compare with that of a plant species found at high latitudes? Explain your answer
Answer:
The carrying capacity of a plant species expect in the equator is higher as compared to the carrying capacity at high Latitudes. This is due to the equator the plants have more light available, so the ecosystem can give them better conditions to survive and reproduce. Remembering that the carrying capacity is the largest population size an ecosystem can support without degrading itself, in the equator would be higher as it can have better conditions of light, so they would survive and reproduce more and the largest population the ecosystem could support would be higher.

In human populations of northern European origin, the disorder called hemochromatosis causes excess iron uptake from food and affects one in 200 adults. Among individuals 15 to 50 years old, men are ten times as likely as women to suffer from iron overload. Part A Taking into account this range of ages, what explains this difference
Answer:
Females of reproductive age lose iron through menstrual blood
Explanation:
Iron is an essential micronutrient involved in the formation of hemoglobin, myoglobin and many enzymatic groups. Moreover, hemochromatosis is a genetically inherited disorder caused by mutations in genes associated with the processes of absorption, transport and storage of iron. The excess of iron is stored in different organs (e.g., liver, heart, pancreas, etc), causing characteristic tissue damage. During each menstrual cycle, women and girls suffer a blood loss of approximately 40 ml, which is associated with an average loss of 1.6 mg of iron. In consequence, it is expected that women of reproductive age (ie, 15–49 years) lose iron during their menstrual periods, thereby avoiding iron overload caused by hemochromatosis.
You are out hiking and walk past a great outcrop of granite that is part of an exposed batholith. Looking closer you notice pieces of sandstone within the batholith. Which rock is OLDER, the granite or the sandstone?
Answer:
Sandstone is younger than the granite rocks
Explanation:
As the rocks layer found at the bottom are the oldest and closer to the ground surface are the younger. This is due to the law of superimposition and as when looking at the outcrops you will notice pieces of sandstone within the batholith that indicates that the base is formed by granite and is later cemented by sandstone rockThe energy source for active transport is ________ , while the force driving facilitated diffusion is ________.
