what is the main point of the villi
Answer:
The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions. The villi number about 10 to 40 per square millimetre (6,000 to 25,000 per square inch) of tissue.
In order to perceive forms and patterns from incoming stimuli, individuals utilize____.
A. feature analysis
Group of answer choices.
A. feature analysis
B. change blindness
C. selective attention
D. inattentional blindness
Answer:
A. feature analysis
Explanation:
Stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ. Therefore, the senses are necessary for behavior because stimuli must be sensed in order to respond.
Stimulus control can be defined as a phenomenon that arises when a living organism responds or behaves in the presence of a stimulus and in another way in the absence of a stimulus.
For example, opening the door of a microwave oven as soon as its timer beeps.
Example II; When your body touches a hot object, you quickly move away and feel some pain subsequently.
In order to perceive forms and patterns from incoming stimuli, individuals utilize feature analysis of the signals from the environment.

Storz (2007) describes an adaptive response to low partial pressure of oxygen in an environment at high elevation. Describe three other environmental conditions besides high elevation that might result in adaptation to hypoxia. List an organism found in each of the described environmental conditions that would be predicted to exhibit adaptive responses to low partial pressure of oxygen.
Answer:
Enhanced ventilatory abilities, enhanced percentage removal of O2 from the ventilatory stream and large gill surface areas.
Explanation:
Enhanced ventilatory abilities, enhanced percentage removal of O2 from the ventilatory stream and large gill surface areas are the three other environmental conditions besides high elevation that might result in adaptation to hypoxia. These abilities will increase the resistance to lower oxygen levels in the surrounding environment. Fish is the organism which used these types of adaptation for their survival in the surrounding of low oxygen levels.

As you are walking home from studying at the library late one evening, you get startled by a strange sound behind you. This activates your sympathetic nervous system. What affect does this change have on stroke volume? Group of answer choices Stroke volume will increase due to an increase in contractility. Stroke volume will decrease due to reduced blood pressure. Stroke volume will increase due to increased blood pressure. Stroke volume decreases due to an increase in contractility. Stroke volume will increase due to a decrease in contractility.
Answer:
Stroke volume will increase due to an increase in contractility.
Explanation:
When the individual is going through a stressful situation, the sympathetic nervous system, in conjunction with the hypothalamic-pituitary-adrenal (HPA) system, sends signals to prepares the body for stressful situations.
The body gets ready to respond to stress by increasing heart biting frequency and strength, contractibility, blood pressure, stimulating respiration and dilating respiratory tracts.
Stroke volume refers to the blood volume ejected from the ventricles as a result of the heart contraction. As said before, stressful situations increase heart bitting frequency and strength, as well as contractibility. Contractibility also influences stroke volume.
Stroke volume is determined by the difference in values of the end-diastolic volume and the end-systolic volume → SV = EDV - ESV
Contractility is one of the main factors that influence stroke volume, by affecting the end-systolic volume. It does not alter the diastolic volume. Consequently, there is an increase in stroke volume.
The central factor of systolic ejection is the myocardium sarcomere contractibility. The sarcomere´s contractile capability generates strength to become shorter after myosin heads join to the uncovered actin-binding points forming cross-bridges.

A biologist explored a remote island and discovered a new living organism. After several observations were made of the
organism, the biologist claimed that it was a vascular plant. His notes are listed below.
"I have found a new organism during my explorations. The organism was found low to the ground and is green. Based on
experiments, the organism seems to require sunlight to survive. Small, oval seeds were
found on the organism; they grew
into identical organisms when put in the soil. The organism had sharp spikes around the main body, most likely for
protection. The organism was able to absorb water from the surrounding soil. It was also observed that the organism used
specialized veins to carry water throughout its body. Based on these observations and experiments, I have determined that
this organism is a vascular plant."
Which of the following observations LEAST supports his claim?
A)
The organism is low to the ground.
B)
The organism reproduces with seeds.
The organism requires sunlight.
D)
The organism was able to transport water through specialized veins.
Answer:
The organism requires sunlight.

how contractile vacuole function in osmoregulation
Answer: A contractile vacuole (CV) is an organelle, or sub-cellular structure, that is involved in osmoregulation and waste removal. ... In freshwater environments, the concentration of solutes inside the cell is higher than outside the cell. Under these conditions, water flows from the environment into the cell by osmosis. The contractile vacuole (CV) complex is an osmoregulatory organelle of free-living amoebae and protozoa, which controls the intracellular water balance by accumulating and expelling excess water out of the cell, allowing cells to survive under hypotonic stress as in pond water.

determines which end of the egg will become the head and which end will become the tail.
is found only in adult somatic cells.
Answer:
represses gene transcription and promotes mRNA translation.
Explanation:
Homeotic gene refers to any group of genes that controls the pattern of formation of body structure during early embryonic development of organisms. These genes encode proteins which is called transcription factors that direct cells to form various parts of the body. Homeotic genes is the master control genes that regulate other groups of genes that are responsible for the development of body parts that will develop in different locations.
