Answer: C
Explanation:
Viruses don't have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat. Unlike bacteria, which attack your body's cells from the outside, viruses actually move into, live in and make copies of themselves in your body's cells

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.
What is the correct series of steps for the movement of energy in an ecosystem?
Answer:
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another; the levels in the food chain are producers, primary consumers, higher-level consumers, and finally decomposers.
Explanation:
Answer:
The flow of energy is always unidirectional. The energy passes from primary producers to primary consumers. From the primary consumers, the energy is passed to secondary consumers and then to tertiary consumers. Thus the energy pyramid is always upright.

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.

A homeotic gene is
Group of answer choices
represses gene transcription and promotes mRNA translation.
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.

how does natural selection lead to evolution
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.
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.
