2. How do thermometers work?

Answers

Answer:

1.a current in a fluid that results from convection.

2.measures temperature through a glass tube sealed with mercury that expands or contracts as the temperature rises or falls.

Explanation:

Answer:

1.A convection current is a process that involves the movement of energy from one place to another. It is also called convection heat transfer. What is the reason that makes you feel hotter when placing hands above a campfire or when sitting next to it? Or, why is the movement of liquid so rapid when water is boiled in a pot? These things happen as a result of the Convection Currents.

Which protein is damaged at the nerve endings during mercury toxicity
a. keratin
b. tubulin
c. pilin

Answers

Answer:

b. tubulin

Explanation:

Tubulin is a superfamily of proteins that make up microtubules who have many functions including intracellular trasport of neuron's vescicles

Tubulin protein is damaged at the nerve endings during mercury toxicity.

What do you mean by Mercury Toxicity?

Mercury toxicity occurs when an individual is highly exposed to mercury.

The inhalation of mercury vapor can produce harmful effects on the nervous, digestive and immune systems, lungs, and kidneys, and may be fatal. This is considered as one of the severe toxicity that a person suffers.

Tubulin proteins are a very important class of proteins that helps in the formation of microtubules that have numerous functions in our body including the cytoskeletal arrangement of cells, intracellular transport of neuronal vesicles. And when a person suffers from mercury toxicity, such proteins are damaged and result in improper conduction of nerve impulses.

Therefore, Tubulin protein is damaged at the nerve endings during mercury toxicity.

Which substance has a low albedo?
A. A black asphalt road
OB. A beach of white sand
O O O
C. A shiny building
D. An iceberg

Answers

It’s a guess but it’s not C. Because that would be high albedo. Low albedo would probably be D. An Iceberg

Explanation: Albedo is the measure of the reflectivity of a material. A high albedo means it reflects a lot of light and a low albedo means it absorbs a lot of light.

My Second Explanation: The higher the albedo, the more the surface reflects light. Snow and ice have high albedos; a dark rock would have a lower albedo.

Nanotechnology produces new and faster kinds of computers, more efficient power sources and more effective medical treatments. Main disadvantages include threats to security, privacy, health and the environment. More research must be done in this field to get more benefits from it.

7. Apply: Look carefully at the picture below and you will see an insect called a
katydid. Katydids evolved from grasshoppers through natural selection. Use
what you have learned to explain how this could have happened.

Answers

Answer: This description is an example of camouflage adaptations.

Explanation:

The grasshoppers are the insects which feed on plant parts and they are able to change their color with respect to their surrounding environment. For example, if they are living on the brown tree trunk they change their color to brown and on the green grass or green leaves they change to green to remain undetected by the predators. This way they are able to camouflage their predators this adaptation allows their survival in their environment with due course of natural selection. The phenotypic trait that is grasshopper is able to change its color increases the chances of survival of the grasshopper. Kaytids have evolved from grasshoppers means they have camouflage traits as that in parent grasshopper species. They have structure which blends with surrounding environment, that is they have wings that mimic that of pattern of leaf venation, also when they change the color to brown the shape of the body appears to be as that of stem. This structural adaptation help them to camouflage their predators.

Perhaps no one cares more about being able to see in the ocean than do divers. The Cayman Islands, Bonaire and the Bahamas are all popular dive destinations due to both submarine features, such as coral reefs, and water clarity. Under the best of circumstances, visibility in these locations is between 50 ft (15 m) to 150 ft (45 m). Based on this, and what you have learned about sound, write a paragraph describing those ways in which humans and marine organisms use sound for some underwater tasks and light for others.

Answers

Answer:

Humans and marine organisms use sound finding depth of the ocean and objects.

Explanation:

Humans and marine organisms use sound for some underwater tasks such as finding depth of the ocean and objects. Human use sonar which is a device used to explore the ocean and animals use echolocation to find food and identify objects that comes in their way. Sonar is present in submarine uses sound waves to detect objects that comes in their way so both humans and marine organisms use sounds.

The following chemical equation shows the combustion of ethane. Balance the equation by filling in the coefficients.

Answers

Answer:

2 C2H6 + 4 O2 → 2 C + 2 CO2 + 6 H2O

Explanation:

2 C2H6 + 4 O2 →  2 CO2 + 6 H2O is the balance equation for the combustion of ethane. In the question, the equation for combustion of methane is unbalanced i. e. C2H6 + O2 → CO2 + H2O so by putting coefficient 2 in front of ethane, 4 in front of oxygen, 2 in front of carbondioxide and 6 in front of  water which can balance the unbalanced equation for combustion of ethane

The role of the RNA-induced silencing complex (RISC) in RNA interference is to cleave tRNAs to slow the rate of translation. disrupt gene expression by cleaving mRNAs that are complementary to the guide strand of the RNA duplex that was introduced. cleave the introduced RNA duplex. disrupt gene expression by interfering with mRNA export to the cytoplasm. create a passenger strand to bind to the mRNA and keep the mRNA from being translated.

Answers

Answer:

disrupt gene expression by cleaving mRNAs that are complementary to the guide strand of the RNA duplex that was introduced

Explanation:

The RNA-induced silencing complex (RISC) is a ribonucleoprotein complex composed of proteins that associate with regulatory small non-coding RNAs (sncRNAs) such as, for example, microRNAs (miRNAs) and small interfering RNAs (siRNAs) in order to regulate gene expression by the RNA interference (RNAi) pathway. These sncRNAs (around 18-30 nucleotides in length) are complementary or nearly complementary to messenger RNAs, thereby they can bind to target mRNA sequences in order to trigger RNAi via mRNA degradation, translational repression, etc. The core component of the RISC complex is an evolutionary conserved Argonaute (Ago) protein that cleaves target mRNAs.

QUESTION 1
Which of the following statements are true of arteries and veins? (Read carefully and select all of the correct statements.)
A. Venous anastomoses ensure that oxygenated blood will get to tissues.
B. The endothelium of both arteries and veins contributes to the prevention of abnormal clotting.
C. The smooth muscle layer of veins is thicker than that of arteries because veins are farther from the heart.
OD. Only veins have valves, which keep the blood moving between heartbeats.
E. The fibrous connective tissue layer of arteries is relatively thin because the blood is moving fast.
OF Arterial anastomoses ensure that blood will be able to return to the heart.

Answers

Answer: B, D

Explanation:

Is this a Med School K Question? The endothelial lining of blood vessels have many functions, including, preventing clotting. Veins carry blood that has very low pressure and have valves to control the one-way flow of blood. The rest are false. Only the pulmonary vein carries oxygenated blood. Arteries have more smooth muscles than veins. The anastomoses are present to act as alternative pathways to reach cells.

Which statement best explains the ideas of phyletic gradualism and punctuated equilibrium?

A. Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is
B. Phyletic gradualism states that many species evolve rapidly at specific points in time, and punctuated equilibrium states that speciation occurs constantly over time
C. Phyletic gradualism states that speciation occurs constantly over time, and punctuated equilibrium states that many species evolve rapidly at specific points in time
D. Phyletic gradualism is supported by the fossil record, but punctuated equilibrium isn't

Answers

A is the correct answer

A. Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is

Punctuated equilibrium and phyletic gradualism are two opposing evolutionary tendencies that can be seen in the geological record. Species in punctuated equilibrium tend to demonstrate morphological stasis between rapid speciation episodes, whereas species in phyletic gradualism change more frequently. "Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is," says the statement that best summarizes the ideas of phyletic gradualism and punctuated equilibrium.
