Answer:
Genetic analysis, structure analysis and study the behaviour.
Explanation:
Genetic analysis, structure analysis and study the behaviour of organisms are the observations or tests that would make it possible to determine whether it is a protozoan, fungus, or algae because these analysis provides information about the genetic makeup and structure of their cell. If the cell wall is made of chitin then it is considered as fungi, if the cell wall is made of peptidoglycan then it is an algae and if the cell wall is not present then it is considered as animals like protist.

1. Cerebral Cortex
2. Hypothalamus
3. Brainstem
4. Spinal Cord
(1)The cerebral cortex, also known as the cerebral mantle, is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. The cerebral cortex mostly consists of the six-layered neocortex, with just 10% consisting of allocortex.
(2)The hypothalamus is a small region of the brain. It's located at the base of the brain, near the pituitary gland. While it's very small, the hypothalamus plays a crucial role in many important functions, including: releasing hormones. regulating body temperature.
(3) The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata Ten pairs of cranial nerves come from the brainstem.
(4)The spinal cord is a long, fragile tubelike structure that begins at the end of the brain stem and continues down almost to the bottom of the spine. The spinal cord consists of bundles of nerve axons forming pathways that carry incoming and outgoing messages between the brain and the rest of the body.

In pulsus paradoxus, even if the pulse cannot be palpated, it can still be heard by using a BP cuff and stethoscope.
a. True
b. False
Answer:
False.
Explanation:
Pulse can't be heard by using a BP cuff and stethoscope because these devices are used to measure the heartbeat and blood pressure of the body. Digital monitors display both blood pressure and heart rate, but you can determine the pulse by checking your pulse by using hand while on the other hand, heartbeats can easily be heard using a good stethoscope so we can say that pulse can't be heard through BP cuff and stethoscope.

Discuss how important you think it is to protect ecosystems from human-induced change, such as changes in habitat or introduction of invasive species. Should natural conditions be preserved at all costs, should human needs always prevail, or is the answer somewhere in between? Discuss the negative consequences of taking an approach that you disagree with.
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. ecosystems are vital for human welfare and survival, as they provide us with essential products and benefits.
Over 90% of our food comes from terrestrial ecosystems, which also provide energy, building materials, clothes, medicines, fresh and clean water, and clean air. Protecting wildlife and preserving it for future generations also means that the animals we love don't become a distant memory. And we can maintain a healthy and functional ecosystem.

Which two of these characteristics does an organism with bilateral symmetry possess?
Answer:
symmetrical in many ways across a central axis" and "presence of a head".
Explanation:
Bilateral symmetry is a characteristic that many organisms has at which if we divide the body using an imaginary line, we will see two mirror images. Two characteristics that an organism with bilateral symmetry possess are symmetrical in many ways across a central axis (known as well as the sagittal plane), and presence of a head that is at the middle of the central axis. The great majority of organisms posses bilateral symmetry, including the humans.

stay safe healthy and happy...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

A technological advancement is an attempt to develop current materials, devices, products or processes by further understanding of science. technological advancement provides innovations of existing technology or formation of new technology in order to better the life style and make easier our work. If the technological advancement did not occur, we are unable to increase efficiency of various instruments and machines.
The protein calcineurin binds to the protein calmodulin with an association rate of 8.9 × 103 M-1s-1 and an overall dissociation constant, Kd, of 10 nM. The dissociation rate kd is:_____. Please explain step by step.
A. 8.9 × 10^3 M-1s-1
B. 8.9 × 10^2 s-1
C. 1.1 × 10-10 s-1
D. 8.9 × 10-5 s-1
Answer:
D
Explanation:
From the information given:
Association rate [tex]K_a[/tex] = [tex]8.9 \times 10^3 M^{-1}s^{-1}[/tex]
dissociation constant [tex]K_D[/tex] = 10 nM
dissociation rate [tex]K_d[/tex] = ???
Using the following relation from equilibrium dissociation constant to determine the dissociation rate, we have:
[tex]K_D =\dfrac{ K_d}{K_a}[/tex]
[tex]K_d = K_D \times K_a[/tex]
[tex]K_d =(10*10^{-9} \ M) \times (8.9*10^3 \ M^{-1}{s^{-1})[/tex]
[tex]\mathbf{K_d =8.9*10^{-5} \ {s^{-1}}}[/tex]
130 and 14C are isotopes of 12C, which has 6 electrons, 6 protons, and 6 neutrons. What is the arrangement of subatomic particles in 14c?
A. 6 electrons, 7 protons, and 6 neutrons.
The correct answer is C. 6 electrons, 6 protons, and 8 neutrons.
Explanation
An isotope is a type of atom that is characterized by having a nucleus with a different number of neutrons. Additionally, isotope atoms are those that have the same number of protons in the nucleus (in the case of carbon 6 protons), but different mass numbers. In the case of the isotope of carbon, it has 8 neutrons (2 more neutrons than the regular carbon) and 6 protons in the nucleus, that is, that its mass is 14 (6 protons + 8 neutrons equals 14). According to the above, the correct answer is C.

For the following three cultures, using any resource find out if they are obligate aerobes, facultative anaerobe, or obligate anaerobe- o Escherichia coli o Micrococcus luteus o Clostridium sporogenes
Answer:
Escherichia coli - Facultative anaerobe
Micrococcus luteus - Obligate aerobe
Clostridium sporogenes - Obligate anaerobe
Explanation:
In simple terms, obligate aerobes are organisms that require oxygen to grow and metabolize molecules such as fats and sugars to produce energy. Many animals fall under this category. Other examples are Mycobacterium tuberculosis and Micrococcus luteus.
Facultative anaerobes are organisms (usually bacteria) that can grow both in the presence and absence of oxygen. The most example of this are the Escherichia coli.
Obligate anaerobes are organisms (usually microorganisms) that cannot survive when exposed to normal atmospheric concentration of oxygen. Examples are Clostridium sporogenes and Clostridium botulinum.
Toluene crosses pure lipid bilayers many hundreds of times faster than a related compound, phenylalanine. Suggest two different properties of these molecules that would account for this difference.
Answer:
The lipid bilayer is hydrophobic that is hydrophobic and it can easily cross the lipid bilayer.
Toulene is a hydrophobic and neutral molecule compound so it can easily pass through the bilayer. It is an aromatic compound with a methane group attached to the benzene ring. It is smaller in comparison to Phenylalanine.
Phenylalanine-- It is an amino acid with a benzene ring attached to it. This amino acid is less hydrophobic than the aliphatic amino acids. Because of its less hydrophobic nature, it travels slowly compared to Toluene. It is also larger and has amino and carboxyl groups attached to it. On the other hand, Phenylalanine is a polar compound which has -COOH and -NH2 group. which prevents its delay in its transport across the lipid bilayer.

1. A week after returning from a backpacking trip, four teenagers developed nausea and severe diarrhea. All had consumed untreated water from a stream which doctors concluded was infested with the organism, Giardia. Think about the symbiotic relationships that you studied in this unit. What type of relationship exists between the teens and the organism?
2. As humans burn fossil fuels for energy, the percent of carbon stored in fossils is reduced while the carbon in the atmosphere is increased. If green plants are also being removed, how might the carbon cycle and greenhouse effect be influenced?
3. How are decomposers critical to the carbon cycle?
Answer:
Explanation:
1) The relationship that exists between the teens and the organism (Giardia) is Parasitism. Because in such symbiotic relationship one species (the parasite-Giardia) benefits while the other species (the host- the teens) is harmed.
2) Plants remove Carbon dioxide (a major green house gas) from atmosphere during photosynthesis. But, if plants are also being removed with increase in use of fossil fuels, the CO2 that escapes the fossil fuels will remain in the atmosphere for longer as there are not enough plants to "suck" them back into a stored form of Carbon. Carbon Dioxide increases green hourse effect thus green house effect will increase and earth's temperature might rise due to this.
3) Without decomposers we would not be able to continue the carbon cycle because we could not release the stored carbon from plants and animals into the atmosphere. Decomposers break down dead material from organism and release carbon dioxide into the atmosphere, where it's available to plants for photosynthesis. Without them, we could not recycle nutrients or carbons in our ecosystem and thus, they are critical for the carbon cycle.
How do sinkholes form? Be sure to provide a detailed explanation of sinkhole formation.
Answer:
See below
Explanation:
Over hundreds of thousands of years, layers of rocks like bedrock and limestone erode. Then, a hole or cavity forms when it erodes. Slowly, the matter above the cavity falls in. This causes it to expand. Drought is also another reason that sinkholes form in the ground.
Answer:
Sample Answer edge 2021
Explanation:
When it rains, rainwater, which is slightly acidic, soaks into the ground and becomes more acidic as it moves through the soil. When this water comes in contact with the bedrock, it reacts with the limestone, dissolving it. As the water flows through the ground, it carries the dissolved limestone away with it, enlarging the natural holes and cracks that were already present in the rock. Over time, large cavities may form in the bedrock. Sinkholes often form when the overlying sediments become too heavy for the ceiling of an underground cavity to support. The ceiling gives way and the overlying sediments collapse into the cavity.
