After trying to push the heavy barrel up the ramp, the man decides to use a shorter ramp leading up to the landing. Will this ma

ke it easier or more difficult to roll the barrel up the ramp? Explain. A) More difficult because the steeper slope requires more effort force to overcome gravity. B) More difficult because the barrel's mass will increase. C) Less difficult because the steeper slope requires less effort force to overcome gravity. D) Less difficult because the effect of the earth's gravity on the barrel will decrease.

slavikrds [6]

Answer:

pressure of the gas inside the lungs will be =1.35 atm

Explanation:

so for calculation of pressure of gas we will use the formula

(remember to convert *C to kelvin)

PV₁/T₁ = P₂V₂/T₂           As we know that Temperature = 310.5 k =37 degree

so for pressure P₂

P₂=P₁V₁T₂/T₁V₂

= ((1.00atm)(2.20L)(310.15K))/ ((298.15K) (1.70L)

=1.35 atm

(remember to convert *C to kelvin)

When colorblind women married a male with normal vision, all their daughters have normal vision and all their sons are colorblin
worty [1.4K]

Answer:

X-linked recessive

Explanation:

The trait is a sex-linked trait because the daughters are not colorblind, but the sons are. We know this its recessive because the daughters have inherited the mother's X chromosome that has the colourblindness trait, but are not colorblind because the father's X does not have the colourblindness trait. The sons are colourblind because they inherited the X from their mother with the colourblindnese trait and a Y from their father. The colourblindness trait or normal vision trait is not carried on the Y, so the mother's X chromosome's trait is expressed.

Sorry if it's confusing i tried my best to explain it

How might adding trees, other plants, and phytoplankton to the biosphere impact global climate change?
astraxan [27]

Answer:

B) The biosphere will absorb carbon dioxide, and the temperature of the atmosphere may decrease or the warming of the atmosphere will slow.

Explanation:

The Climate is constantly influenced by changes caused by the increase in global temperature called Global Warming. Global warming is caused by the emission of green house gases which includes carbondioxide (CO2). Hence, one way to prevent the climate from further deterioration is to find a way of removing gases like CO2 from the atmosphere.

Plants like trees and phytoplanktons like algae are photosynthetic organisms. This means they have the ability to perform the process of photosynthesis, which is the usage of light energy from sun to synthesize food in form of organic molecules (glucose) from an inorganic source. The inorganic source is Carbondioxide (CO2). Plants take in CO2 via the stomata on their leaves. Carbondioxide is a vital raw material for photosynthesis, hence, the photosynthetic process helps remove Carbondioxide from the atmosphere.

If trees, other plants, and phytoplankton are added to the biosphere, they will perform photosynthesis and absorb a good amount of Carbondioxide (CO2), which contributes to global warming, from the atmosphere. Hence, the temperature or warming of the atmosphere caused by global warming will decrease.
