How is oxygen carried from the lungs to the tissues?
a. It is carried by cilia through the bronchioles.
b. It binds to a protein called hemoglobin in red blood cells.
c. It leaves the alveoli and enters mucus.
d. It leaves the bronchi and enters capillaries.
Answer:
Oxygen transport within the human body occurs through both convection and diffusion. ... Oxygen diffuses from both the alveoli into the pulmonary capillaries and the systemic capillaries into the tissues, according to Fick's laws of diffusion and the random walk of the diffusing particles
Explanation:
Hope this helps
Answer: It binds to a protein called hemoglobin in red blood cells.
Explanation:
Haemoglobin (Hb) is a protein found in the red blood cells that carries oxygen in your body and gives blood its red colour.

Why is it necessary for the cell to grow and duplicate its DNA before the start of meiosis?
Answer:
Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis. Since the cell is dividing it needs two copies of its DNA - one is kept by the parent cell and the other is passed to the daughter cell. ... So this process of duplicating DNA is very important.
Viruses replicate the host cell
True, viruses replicate the host cell
False, viruses replicate the virus, inside the host cell
Answer: False viruses replicate the virus inside the cell so that it will overfill and burst and let the viruses infect other cells.

If no energy is transferred, how much work is done?
Answer:
Explanation:The potential energy is converted to kinetic energy in the process. But I see no transfer of energy between the earth and the body.
And how does energy transfer takes place in case of negative work ? When a body is moved across a surface which has friction, the friction does negative work. Does it mean that a sort of energy transfer occurs between the surface (source) and the body (object

Identify the 2 constructive processes from the list below.
A) A river wears away the land creating a canyon.
B) Over time a mountains top becomes less jagged and more rounded.
C) A volcano erupts and lava flows down its sides.
D) Silt is deposited at the mouth of a river.
Answer:
C, D.
Explanation:
C: The flowing lava creates extra rock. For example, entire islands are formed via this process of volcanos erupting, lava cooling, repeat.
D: Silt from erosion (erosion itself is considered destructive, but the resulting silt can turn into something constructive.) can build up entire mounds or mountains over time.
how do homologous structures develop
Answer:
Explanation:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor.the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor.

Which type of precipitation is most likely to occur when both air and cloud temperatures are above freezing?
A) Rain
B) Snow
C) Hail
D) Sleet
Answer:
it should be A or rain to be specific
Answer:
rain
Explanation:
If the ar is above freezing, the precipitation will most likely be rain. If the air is below freezing, the precipitation will most likely be snow. When air temperature is only a few degrees above freezing, precipitation may fall as sleet. Hail is most commonly formed within the cumulonimbus clouds of thunderstorms.
Which of the following statements about natural selection is true:
• Individual organisms change over time
•Populations of organisms change over time
•Organisms do not change over time
Answer:
Option 2 (Population of organisms change over time.
A piece of wood that measures 3cm by 6cm by 4cm has a mass of 80g.
What is the density of the wood?
Answer:
1.1 would be the densiry
explanation
p=m/v is the density formula p being density and m being mass and v being volume
multiply 3 by 6 by 4 to get volume of 72
80÷72 = 1.1

if glucose is in higher concentration outside the cell than inside, but the plasma membrane and other surface layers of the cell do not allow glucose to pass through, which is the most likely type of transport for glucose? and Why?
a simple diffusion
b Osmosis
c Facilitated diffusion via a gated channel
d Facilitated diffusion via an aquaporin
e Facilitated diffusion via an ion channel
Answer:
a
Explanation:
ok ok as you were saying you said it is hard for the glucose concentration in the body this also had to go out so but the plasma membranes and other surfaces layers cell layers of the layer of the soil do not allow to close glucose to pass through which is most likely type of transport type of transport for kids and you still said why it is because it gives energy to the body

What do biogeochemical cycles represent?
Answer:
Explanation:
Biogeochemical cycles represent the main system by which the energy of the Sun is transformed into energy of the chemical compounds by living beings and products of their activity. :)
Answer:
Biogeochemical cycles represent the main system by which the energy of the Sun is transformed into energy of the chemical compounds by living beings and products of their activity.
Which is correct if it is not correct, correct it.
Simple or facilitated diffusion requires cellular energy.
Diffusion results in a net flow of solute down a concentration gradient, while active transport works against the concentration gradient.
Secondary active transport uses energy to set up a concentration gradient which then allows some passive diffusion to occur, recapturing some of the energy expended.
Membrane proteins are required for all membrane transport into and out of cells.
