Hormones that are secreted by one endocrine gland (i.e., anterior pituitary gland) and control the secretion of a hormone from another endocrine gland (i.e., adrenal gland) are generally called _____________ hormones.
A. tropic
B. glucocorticoid
C. activation
D. blood releasing
Answer:
A. tropic
Explanation:
Generally, hormones are chemical messengers that are secreted in a particular location and transported to another location to effect a physiological response. However, some set of hormones secreted by an endocrine gland functions in stimulating or regulating the secretion of other hormones by another endocrine gland. These group of hormones are called TROPIC HORMONES.
As stated in this question, the anterior pituitary gland, which is considered to be the "MASTER GLAND" secretes an hormone that controls the secretion of another hormone by adrenal gland. The hormone secreted by the PITUITARY GLAND is a TROPIC HORMONE. An example of tropic hormone is ADRENOCORTICOTROPIC HORMONE (ACTH) secreted by anterior pituitary gland.

The illustration shows one of the ways resources are removed from the deep sea. Describe what type of resources these are, including if they are renewable or non-renewable. Predict two consequences to the seafloor life if this process is not regulated.
Answer:
Marine mining is a process that can be done by dredging the seabed and is used for the extraction of mineral resources from the seabed, which are non-renewable, with a negative impact on marine ecosystems.
Explanation:
The illustration shows a process of marine mining by dredging, where the resource extracted is of a mineral nature, like copper, zinc, silver and gold. Gravel used for construction can also be extracted from the sea. Mineral resources extracted from the sea are not renewable.
The process of marine mining can be harmful to the ecosystems there, so it must be a process that requires control and management from the ecological point of view.
Two possible consequences of not regulating marine mining are:
Destruction of the habitat of life forms present on the sea floor, which endangers many species and even forces migration to more stable areas, with consequences on the food chains. Extinction of marine species that inhabit the seabed. The flora and fauna of the sea floor usually have slow reproductive cycles and, in the case of fish, spawning takes place on the bottom of the sea. Mining endangers the reproductive cycles of the species, leading to induced extinction.Responsible and controlled mining activity can be useful for humans, while avoiding negative consequences on the ecosystems that exist at the seabed.

Choose a specific site for further study where eutrophication is a problem (such as Chesapeake Bay, the Baltic Sea, or the Gulf of Mexico). List some sources of nitrogen and/or phosphorous to the water body and describe some of the ecological problems due to eutrophication at this specific site.
Explanation:
Due to the commercial farming activities in the MidWest, fertilizers and pesticides are usually washed away by precipitation and drain into the Gulf of Mexico. These elements (mainly nitrogen and phosphorus) offer much nutrients for algae causing them to thrive into algae blooms. Bacteria then find ‘fodder’ in dead algae breaking them down for energy sources. The bacteria, mostly aerobic, take up most of the oxygen from the water as they thrive. This makes the waters of the Gulf hypoxic hence the other marine organisms such as fishes cannot thrive. Actually, the ecosystem dies and the region is recognized as a' dead zone'.

Answer:
Cytochrome C is a protein found in all species, and functions in energy metabolism. The more closely related two different species are,
C. the greater the number of differences there are in their amino acid sequences in cytochrome C.
Explanation:
Cytochrome c, unlike other cytochromes, is highly water-soluble. It is an essential component of the electron transport chain, where it transfers electrons between complex III and complex IV of the respiratory chain. It undergoes oxidation and reduction when its iron atom converts between the ferrous forms to the ferric forms, but it does not bind to oxygen.
The energy used to pump hydrogen ions from the mitochondrial matrix across the inner membrane and into the intermembrane space is derived from:________
a. ATP hydrolysis
b. reactions in the electron transport chain
c. decreasing the pH in the mitochondrial matrix
d. splitting water to form oxygen and protons
Answer:
b. reactions in the electron transport chain
Explanation:
Oxidative phosphorylation, which is the process described in this question, is the third stage of cellular respiration which occurs in the MITOCHONDRION of eukaryotic cells. In this stage of oxidative phosphorylation, which encompasses electron transport chain (ETC) and chemiosmosis, ATP is synthesized.
The ATP is synthesized when protons (H+) move from the mitochondrial matrix into the intermembrane space, forming, a proton pump. The series of electron transfers (reactions) that occur in the complexes of the ETC provides the ENERGY to pump the protons/hydrogen ions out of the matrix, which creates the electrochemical gradient required for ATP synthesis with the help of ATP synthase.

The drug 2,4-dinitrophenol (DNP) destroys the proton gradient across the inner mitochondrial membrane. What would be the effect of incubating isolated mitochondria in a solution of DNP
Answer:
This question lacks options, options are:A) Oxygen would no longer be reduced to water. B) No ATP would be made during transport of electrons down the respiratory chain. C) Mitochondria would show a burst of increased ATP synthesis. D) Glycolysis would stop. E) Mitochondria would switch from glycolysis to fermentation.The correct answer is B)
Explanation:
The main mechanism of ATP production takes place in our mitochondria, which are cellular organelles, and this occurs when molecules of coenzymes or reduced prosthetic groups, coming from the process of catabolism of nutrients, are oxidized with molecular oxygen (which becomes in water), leading to the production of ATP. DNP works by increasing heat production in cells through a process known as decoupling. Dinitrophenol is an ionphoric compound that cuts mitochondrial ATP production circuits. This cessation of ATP production through the mitochondria leads to an increase in metabolic rate (as the substrate is used at a higher rate so that cytosolic ATP can sustain life) and subsequent weight loss.
Which of the following should result in a population reaching its carrying capacity sooner?a. reducing intrinsic growth rate rb. increase the intrinsic growth rate rc. decreasing the carry capacity kd. increasing the carry capacity ke. increasing initial population size No
Answer:
b. increase the intrinsic growth rate
Explanation:
Increase in the intrinsic growth rate will result in a population reaching its carrying capacity sooner because population of organisms increases due to increase occur in intrinsic growth rate. Increase in intrinsic growth rate means more organisms are born as compared to death of that organism which results in increase population and with the increase in population, carrying capacity of that environment filled very soon..
