A ball is dropped from height of 45 m. A second ball is thrown downwards from the same
with an initial vity both the balls reach the ground at the same time, culate the value of u
Answer:
h = 45 m
g(acceleration due to gravity) = 9.8 m/s^2 or 10 m/s^2
Final velocity ( v ) = 0 m/s
v = ?
we know theirs equation of motion, v^2 = u^2 + 2gh
0 = u^2 + 2(-10)(45) [ The acceleration due to gravity is ALWAYS negative. Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing.]
0 = u^2- 900
900 = u^2
u = √900 = 30 m/s

As per the experimental values, When the temperature decreases the time taken for the starch to be digested increases. This means that when the temperature is decreased, the metabolic rate also decreases resulting in the decrease in the rate of digestion. As we decrease the temperature everytime by the value of [tex]10^0[/tex]C, the rate of reaction decreases by the factor of 2.
_____________________________________A2)The slowest experiment was at Temperature [tex]20^o[/tex]C by the rate of 0.066 and The fastest experiment was at Temperature [tex]40^o[/tex]C by the rate of 0.32.
REASON:The reactants must contain sufficient kinetic energy to overcome a barrier called Activation Energy. Activation energy is the minimum amount of energy required to change the reactants into products. The Fastest reaction is at high temperature because when the temperature increases the molecules collide with one another more frequently, when the kinetic energy increases, more molecules make the effective collisions due to, so more molecules make up to the threshold energy. So increase in temperature increases the rate of the reaction.
_____________________________________A3)The optimum temperature for enzyme amylaze is 40 degree C because it has the fastest rate of reaction at that temperature. At high temperatures the shape of the enzyme is altered so that it is no longer complementary to its specific substrate., thus optimum temperature is 40 degrees, that is the reason why human body has temperature of 40.

A) less likely to produce offsprings
B) less likely to be eaten by birds
C) more likely to make with monarchs
D) more likely to eat milkweed
Answer:
B Trust me
Explanation:
Less likely to be eaten by birds
The similarity in appearance between monarch butterflies and viceroy butterflies developed because viceroy butterflies that closely resemble monarchs are less likely to be eaten by birds. Thus, option B is correct.
What are viceroy butterflies?Limenitis archippus is scientific name of viceroy butterflies which is a North American butterfly. Since the viceroy is distasteful to predators, it is considered a Müllerian mimic.
The viceroy found in most of the contiguous United States as well as parts of Canada as well as Mexico. The caterpillar of viceroy butterflies feeds on trees in the willow family Salicaceae which includes willows, poplars, cottonwoods. The caterpillars isolate salicylic acid in their bodies, and therefore tastes bitter, and upsets predators' stomachs.
In natural phenomenon called Müllerian mimicry two or more well-defended species, which are foul-tasting and sharing common predators, mimic each other's honest warning signals.
Therefore, Monarch butterflies and viceroy butterflies are less likely to be eaten by birds so option B is correct.

how does the carbon and water cycle work in wetlands? (simple answer please
Answer:The role of wetlands in the carbon cycle
Department of Sustainability, Environment, Water, Population and Communities
Inter-tidal wetlands, such as mangroves, play an
important role in carbon sequestration.
(Shane Cridland)
Wetlands play an important role in landscape function, including cycling of carbon, water and nutrients, food and fibre production, water purification, regulation of flows, provision of habitats, and tourism and recreation services.
The role of wetlands in carbon sequestration and storage has generally been under-estimated. Wetlands cover approximately six to nine per cent of the Earth's surface and contain about 35 per cent of global terrestrial carbon. As wetlands are centres of high productivity in the landscape, they have a high capacity to sequester and store carbon. As depositional areas, wetlands can also store carbon-rich organic sediments. However, under anaerobic conditions, wetlands can also produce greenhouse gases such as methane and nitrous oxide, though this is limited in saline conditions. Clearing or drainage of wetlands can lead to large losses of stored organic carbon to atmospheric carbon dioxide.
Greater consideration needs to be given to the roles of wetlands as carbon sources, sinks and storages when designing climate protection and natural resource programs. Therefore, in consultation with the Wetlands and Waterbirds Taskforce, the Australian Government Department of Sustainability, Environment, Water, Population and Communities has developed an issues paper, The role of wetlands in the carbon cycle. This paper considers the role of wetlands in carbon cycling, the implications of climate change for wetland functions and services, and mechanisms to promote protection and restoration of wetlands for multiple benefits including carbon sequestration.

What is aquatic ecosystem?In contrast to terrestrial ecosystems that are built on land, an aquatic environment is an ecology that is created around a body of water.
Communities of species that depend on one another and their surroundings make up aquatic ecosystems.
An aquatic ecosystem encompasses marine and freshwater habitats such as the ocean, intertidal zone, reefs, seabed, and freshwater habitats such as lakes, ponds, rivers, streams, wetlands, and swamps.
The habitat for all living things that require water, such as animals, plants, and bacteria, is the aquatic ecosystem.
A living thing that alters its surroundings is referred to as a biotic factor. Examples of organisms found in a freshwater habitat include algae, fish, amphibians, and aquatic plants. A particular ecosystem is the result of the interaction of biotic and abiotic components.
As aquatic biome abiotic factors include sunlight, temperature, nutrients, pH (acidity), depth, and salinity, if a chemical company were to dump a large quantity of acid into an estuary, this will increase the pH and also the salinity of water.
Thus, this will adversely affect the biotic life of the aquatic ecosystem.

Make a list of the energy carriers involved in the Krebs cycle. Include their names before and after they accept the electrons.
Answer: All told, the Krebs cycle forms (per two molecules of pyruvic acid) two ATP molecules, ten NADH molecules, and two FADH2 molecules. The NADH and the FADH2 will be used in the electron transport system.
Explanation:
All told, the Krebs cycle forms (per two molecules of pyruvic acid) two ATP molecules, ten NADH molecules, and two FADH2 molecules. The NADH and the FADH2 will be used in the electron transport system.
Kreb's cycle or Tricarboxylic acid cycle is a series of redox reactions, which take place in the mitochondrial matrix. The cycle yields energy in the form of GTP.
The carriers of the cycle are two ATP molecules, reduced 10 NADH and 2 FADH2, two carbon dioxide, and the initial product of two molecules of pyruvate.
The cycle can be described as:
The initial product is pyruvate, which is broken down into a two-carbon compound, acetyl coenzyme A to be utilized in Kreb's cycle. The series of reduction, hydration, oxidation, and dehydration results in the complete breakdown of the glucose.The products yielded from the cycle are carbon dioxide, GTP, NADH, and FADH2.The molecules NADH and FADH2 are the carriers, which are reoxidized in the electron transport chain, to yield overall energy in the form of ATP.Thus, the Krebs cycle yields NADH and FADH2, which enter the electron transport chain.

how air enters from our mouth to toe?
When you breath in air through your mouth (or through your nose, but this question is asking about your mouth) it goes into your lungs. This oxygen then goes to various places round your body, one of these places being your blood stream. When the oxygen enters your blood stream, the blood could travel to your toe. This is how air would enter your mouth and get to your toe.
Answer:
When we breath air, it enters our trachea, which is the main passageway to our lungs. The lungs have something called bronchioles, which put that oxygen into tiny sacs and that air is delivered all across your body through arteries and veins! Vains reach to your toes, hands, and head, so they distribute oxygen everywhere.
In terms of the image below, the box on the top right is the example of the sacs of air in the bronchioles. The larger part of the image to the left is the overall respiratory system, and the arteries on the sacs of air are what deliver the air throughout the body.

a. diffusion
b. active transport
C. endocytosis
d.
a sodium-potassium pump
Answer: diffusion
Explanation: Diffusion expends no energy. Rather the different concentrations of materials in different areas are a form of potential energy, and diffusion is the dissipation of that potential energy as materials move down their concentration gradients, from high to low.
Among the options given, the process of diffusion does not expend or utilize energy. Thus, the correct option for this question is A.
What is Diffusion?Diffusion may be characterized as a type of movement of individual molecules of a substance from an area of higher concentration to an area of lower concentration through a semipermeable barrier. This biological movement cannot utilize any metabolic energy.
According to the context of this question, active transport is a type of transport of individual substance against a concentration gradient that actively require the use of metabolic energy. Apart from this, endocytosis and sodium-potassium pump also required energy for successful function within the body of living organisms.
Therefore, the process of diffusion does not expend or utilize energy. Thus, the correct option for this question is A.
