v)b

vi)c

Answer:

a

Explanation:

a

Answer: a!!

Explanation: this is correct!

Answer:

d

Explanation:

Answer:

the rate of change of velocity with time is called acceleration.

it can also be defined as the increase in velocity per second.

The S.I. unit of acceleration is meter per second square or ms−2.

formula; a = Δv / Δt

where a is acceleration,

Δv is the change in velocity,

and Δt is the amount of time it took for that change to occur.

The correct answer would be that substance A is rice, and substance B is sugar.

For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.

Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.

Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

Explanation:

Answer:

The answer is C.

Explanation:

This is because the objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object.

Energy is transferred from a warmer to a cooler object through the phenomenon of heat. For instance, a large pan of lukewarm water will gain heat from a lit match (a higher temperature object) (lower temperature object). Thus, option C is correct.

It feels warmer in your hands to hold a hot cup. The heat is moving from one object to another, which is what you are feeling. Your hands receive the hot chocolate's thermal energy.

Heat is exchanged when two objects are at different temperatures. Up until the two items are at the same temperature, the cooler object warms up. Always, heat energy moves from a hot object to a cooler one.

The colder end will get energy from the hot end as it passes through the rod. The temperature will eventually equalize across the entire rod. Wearing gloves is crucial when working with hot metal, for this reason.

Therefore, The warmer object transfer heat energy to the cooler object.

Answer:

Water, high specific heat capacity

Explanation:

The temperature fluctuations are relatively small in Jameson city because takes water longer to heat up and cool down due to its high specific heat capacity because water has high heat capacity that is it absorb alot of heat before it start to get hot. takes more energy to increase the temperature of water compared to other substances which help to regulate extremes in the environment.

Water surrounding cities take longer to heat up and longer to cool down so cities that are near the oceans will tend to have less change and less extreme temperatures compared to inland cities.

Answer:

The pulmonary veins carry oxygenated blood to the heart. Air enters the bronchioles in the lungs and reaches the alveoli. The capillaries join together to reach the arteries, transferring the oxygen. The oxygen-rich blood moves from the aorta and reaches the kidneys through a series of blood vessels.

Answer:

Genus, Specific epithet

Explanation:

The scientific name was created to establish a standardized language that would allow scientists and scholars around the world to be able to present living beings independently of their native language.

For this purpose, it was decided that the scientific name would be a binomial composition, that is, it would use two names. The first name refers to the genus to which the species belongs, the second name refers to the specific epithet that is the specific descriptor of that species. In addition, the scientific name should be written in italics and have the first initial letter written in uppercase. Ex: Homo sapiens.

Answer:

Rayleigh wave

Explanation:

Rayleigh waves are a type of surface acoustic wave that travel along the surface of solids. They can be produced in materials in many ways, such as by a localized impact or by piezo-electric transduction, and are frequently used in non-destructive testing for detecting defects.

please mark it the brainliest!

Rayleigh wave, surface acoustic waves called Rayleigh waves move along the surface of solids, hence option D is correct.

They are commonly employed in non-destructive testing to find flaws and can be created in materials in a variety of methods, as by a localized impact or by piezoelectric transduction.

These include what are known as Rayleigh waves. A Rayleigh wave's amplitude decreases with depth below the surface and becomes noticeably tiny at depths greater than a few wavelengths.

As a result, the disturbance is limited to a solid's surface layers. The motion experienced by the surface layers includes both transverse and longitudinal components.

Therefore, Rayleigh wave type of seismic wave is highlighted in the image.

Explanation:

Answer:

Tonicity is the concentration of a solution compared to another, with regards to the number of solutes in these solutions. Too many solutes in a cell may cause them to be hypertonic hence absorb water too much water and lyse. Therefore, these solutes are excreted to the blood-stream through active transport and facilitated diffusion. These solutes are then excreted by the kidneys. If they are not excreted, the osmotic pressure (due to the inflow of water to the bloodstream by osmosis) may cause high blood volumes being pumped by the heart hence high blood pressure

Explanation:

Tonicity is the concentration of a solution compared to another, with regards to the number of solutes in these solutions. Too many solutes in a cell may cause them to be hypertonic hence absorb water too much water and lyse.

The solutes are excreted to the blood-stream through active transport and facilitated diffusion. These solutes are then excreted by the kidneys. If they are not excreted, the osmotic pressure due to the inflow of water to the bloodstream by osmosis may cause high blood volumes being pumped by the heart hence high blood pressure.

Osmosis is the net movement of water across a semi-permeable membrane from an area of lower gradient concentration to an area of higher gradient concentration. On the other hand, tonicity is the ability of an extracellular fluid to make water move into or out of a cell through osmosis. A solution's tonicity is related to its osmolarity or the total concentration of the solutes in a solution.

Therefore, Tonicity is the concentration of a solution compared to another, with regards to the number of solutes in these solutions.

Answer:

Induced fit

Explanation:

Induced fit (IF) is a model used to understand enzyme-substrate interactions, which can be considered as a development of the classical lock-and-key model. This model (IF) was proposed by Daniel Koshland (1958) in order to understand protein conformational changes during the binding process. The model states that the active site of the enzyme, i.e., the region where the substrate binds and catalyzes the reaction, is reshaped when it binds with its substrate in order to improve the fit. The IF model assumes that the active site of the enzyme is flexible and is capable of changing its shape until the substrate is completely bound.

Answer:

the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.

Hey there!

Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunligh, so we eat the plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the reen pigment found in the chlorookasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Answer:

Dramatic evolution within human genome may have been caused by malaria parasite. A genetic mutation that protects people from a common form of malaria spread like wildfire in sub-Saharan Africa about 42,000 years ago, according to a new study.

People develop sickle-cell disease, a condition in which the red blood cells are abnormally shaped, if they inherit two faulty copies of the gene for the oxygen-carrying protein haemoglobin. The faulty gene persists because even carrying one copy of it confers some resistance to malaria.05-May-2011

Explanation:

An evolutionary force, called balancing selection, appears to be responsible for maintaining defects in our DNA associated with diseases, such as sickle cell anemia, because the mutation's damaging effects might be offset — in a biological way of thinking — by its potential benefits.
