____ are responsible for the vast majority of the ocean’s primary productivity. a. phytoplankton b. seaweeds c. extremophiles d. chemosynthetic organisms

Answers

Answer 1

The organisms that are responsible for the vast majority of the ocean's primary productivity are phytoplankton. Phytoplankton are small, drifting organisms that are the base of the marine food chain.

They are autotrophic organisms that produce their food using sunlight via photosynthesis. These tiny organisms can be found in both freshwater and saltwater environments, but are most commonly found in the upper layers of the ocean, where sunlight is abundant.

They are important for the ocean because they are responsible for most of the photosynthesis in the ocean, which means they produce most of the oxygen we breathe. In addition, phytoplankton serve as a food source for a variety of marine animals, including zooplankton, small fish, and whales. Thus, phytoplankton is the correct answer to the question.

Consider a population of lizards living on the coast of Africa. A storm creates piles of debris that the lizards use to raft to a faraway uninhabited island. Which evolutionary process is happening?
A) founder effect
B) bottleneck effect
C) coalescence
D) mutation-selection balance

Answers

The evolutionary process that is happening in the scenario where a storm creates piles of debris that the lizards use to raft to a faraway uninhabited island is founder effect.

The founder effect is a situation that occurs when a small group of individuals breaks off from a larger group to form a new population. These individuals are the founders of the new group, and they carry only a small fraction of the genetic diversity found in the original population.

In other words, the genetic diversity of the new population is constrained by the alleles present in the founding population. Therefore, genetic drift, which is a random variation in the frequency of alleles in a population, will be significant and potentially drive the new population's .

the proximal convoluted tubule is the portion of the nephron that attaches to the collecting duct.

Answers

The statement: "the proximal convoluted tubule is the portion of the nephron that attaches to the collecting duct" is false

Understanding Proximal Convoluted Tubule

The proximal convoluted tubule does not directly attach to the collecting duct. The proximal convoluted tubule and the collecting duct are distinct segments of the nephron, which is the functional unit of the kidney.

The proximal convoluted tubule is located immediately after the glomerulus in the renal cortex. It is responsible for the reabsorption of the majority of filtered water, ions, and nutrients such as glucose, amino acids, and electrolytes. It plays a crucial role in the reabsorption of substances needed by the body while also selectively secreting certain waste products into the tubular fluid.

On the other hand, the collecting duct is a later segment of the nephron that receives tubular fluid from multiple nephrons. It extends from the cortex to the medulla of the kidney. The collecting duct is responsible for further adjusting the composition and volume of urine by reabsorbing water and electrolytes or secreting additional waste products as needed. The collecting ducts from multiple nephrons eventually merge together and empty urine into the renal pelvis for elimination.

The__________nerve transmits afferent impulses for the special senses of hearing and balance.vestibulocochlear

Answers

The vestibulocochlear nerve transmits afferent impulses for the special senses of hearing and balance. This nerve, also known as the eighth cranial nerve, is responsible for carrying sensory information from the inner ear to the brain. It is composed of two branches: the vestibular branch, which transmits impulses related to balance and spatial orientation, and the cochlear branch, which transmits impulses related to hearing.

When it comes to hearing, the vestibulocochlear nerve carries the afferent impulses generated by the hair cells in the cochlea of the inner ear. These hair cells are responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. The impulses travel along the vestibulocochlear nerve to the brain, where they are processed, allowing us to perceive and understand sound.

In terms of balance, the vestibulocochlear nerve carries afferent impulses that provide information about the position and movement of the head. This information is crucial for maintaining balance and coordinating movements. The impulses originate from sensory cells located in the vestibular organs of the inner ear, which sense changes in head position and movement. The vestibulocochlear nerve then transmits these impulses to the brain, where they are interpreted and used to maintain our sense of balance.

In summary, the vestibulocochlear nerve plays a vital role in transmitting afferent impulses for the special senses of hearing and balance. It carries information related to hearing from the cochlea and information related to balance from the vestibular organs.

Explain what a feedback is. (for climate)
Explain what positive and negative feedbacks are. (for
climate)
Give and explain at least two examples of positive feedbacks in
the Earth’s climate system.

Answers

Feedback is the process by which a certain effect is amplified or counteracted by the inputs that initiated it. In the context of climate, feedback refers to the way in which Earth's climate system responds to changes, whether those changes are initiated by natural or human factors. Positive and negative feedbacks are two types of feedback in climate.

Positive feedback amplifies the initial response of the climate system to external factors, resulting in further changes that reinforce the initial response. This may lead to runaway effects in the climate system. A simple example of positive feedback in the Earth's climate system is the ice-albedo feedback. When snow and ice melt, the albedo (reflectivity) of the surface decreases. This means that less sunlight is reflected back into space and more is absorbed by the Earth, leading to further warming. This, in turn, causes more melting, which further reduces albedo, and so on.

Negative feedback counteracts the initial response of the climate system to external factors, resulting in changes that dampen the initial response. This may lead to a stabilizing effect on the climate system. A simple example of negative feedback in the Earth's climate system is the carbon cycle feedback. When atmospheric CO2 levels increase, more CO2 is absorbed by the oceans and terrestrial ecosystems. This, in turn, reduces the amount of CO2 in the atmosphere, leading to less warming.

b) The heads are repelled by the water inside and outside the cell.
c) The tails are nonpolar and form hydrogen bonds with one another.

Answers

The reason for phospholipids spontaneously forming a bilayer in an aqueous solution with the heads of the phospholipids pointing out and the tails pointing towards one another is option A.

The tails are repelled by the aqueous environment, and the heads will directly interact with the aqueous solution. phospholipid bilayer is the basic structure of the cell membrane. It is made up of two layers of phospholipid molecules, each having a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail.

The tails of the phospholipids are made up of fatty acids, which are hydrophobic, while the heads are made up of a glycerol molecule and a phosphate group, which are hydrophilic. Because of this, the heads of the phospholipids will interact directly with the aqueous environment (either inside or outside of the cell) while the tails will avoid water and instead associate with one another.Phospholipids spontaneously form a bilayer in an aqueous solution because the hydrophilic heads are attracted to water molecules, whereas the hydrophobic tails are repelled by water and will interact with each other instead.

how and why where africanized honey bees originally imported to brazil

Africanized honey bees were originally imported to Brazil in the 1950s by a geneticist named Warwick Kerr. Warwick Kerr was a Brazilian geneticist who worked for the Brazilian Ministry of Agriculture in the 1950s.

The goal of his work was to create a new type of bee that could better survive in Brazil's tropical environment and produce more honey. Kerr decided to import African honey bee queens from Tanzania and crossbreed them with European honey bees that were already present in Brazil. The hope was that the hybrid bees would inherit the African bees' hardiness and the European bees' honey-producing abilities.

However, the new hybrid bees turned out to be much more aggressive than either the African or European varieties. They quickly spread throughout Brazil and eventually into other parts of South America, Central America, and the southern United States.The Africanized honey bees are now infamous for their aggressive behavior and tendency to attack in large numbers. Despite this, they are still used for honey production in some areas, and efforts are being made to breed less aggressive strains of the bees.

Incidence rateb. Cumulative incidencec. Point prevalenced. Period prevalence Which of the following statements regarding the Capital Allocation Line (CAL) is false? Multiple Choice The CAL determines the optimal portfolio of a risk-averse investor. The slope of the CAL equals the increase in the expected return of the complete portfolio per unit of additional standard deviation. The slope of the CAL is equal to the Sharpe ratio of the risky portfolio. The CAL shows feasible risk-return combinations. Assume that adults have 1Q scores that are normally distributed with a mean of 99.7 and a standard deviation of 18.7. Find the probability that a randomly selected adult has an 1Q greater than 135.0. (Hint Draw a graph.) The probabily that a randomly nolected adul from this group has an 10 greater than 135.0 is (Round to four decimal places as needed.) There is a0.9985probability that a randomly selected27-year-oldmale lives through the year. A life insurance company charges$198for insuring that the male will live through the year. If the male does not survive the year, the policy pays out$120,000as a death benefit. Complete parts (a) through (c) below.a. From the perspective of the27-year-oldmale, what are the monetary values corresponding to the two events of surviving the year and not surviving?The value corresponding to surviving the year isThe value corresponding to not surviving the year is(Type integers or decimals. Do not round.)Part 2b. If the30-year-oldmale purchases the policy, what is his expected value?The expected value is(Round to the nearest cent as needed.)Part 3c. Can the insurance company expect to make a profit from many such policies? Why?because the insurance company expects to make an average profit ofon every30-year-oldmale it insures for 1 year.(Round to the nearest cent as needed.) center (5,-3)and the tangent line to the y-axis are given. what is the standard equation of the circle For the following reaction. 6.02 grams of silver nitrate are mixed with excess iron (II) chloride.
