Answer:
Fertilized eggs attach to the sides of the uterus, which is in the vagina.
Answer:
Mice have four legs, four feet and one tail per unit-mouse.
There are three types of microscope with the ability to produce three-dimensional images. The scanning electron microscope<span> (</span>SEM<span>) and </span>transmission electron microscope<span> (</span>TEM<span>) both use beams of electrons to produce an image of the sample. The </span>confocal<span> laser scanning microscope uses a laser beam to produce an image.</span>
Answer:
0.153
Explanation:
We know the up-thrust on the fish, U = weight of water displaced = weight of fish + weight of air in air sacs.
So ρVg = ρ'V'g + ρ'V"g where ρ = density of water = 1 g/cm³, V = volume of water displaced, g = acceleration due to gravity, ρ'= density of fish = 1.18 g/cm³, V' = initial volume of fish, ρ"= density of air = 0.0012 g/cm³ and V" = volume of expanded air sac.
ρVg = ρ'V'g + ρ"V"g
ρV = ρ'V'g + ρ"V"
Its new body volume = volume of water displaced, V = V' + V"
ρ(V' + V") = ρ'V' + ρ"V"
ρV' + ρV" = ρ'V' + ρ"V"
ρV' - ρ"V' = ρ'V" - ρV"
(ρ - ρ")V' = (ρ' - ρ)V"
V'/V" = (ρ - ρ")/(ρ' - ρ)
= (1 g/cm³ - 0.0012 g/cm³)/(1.18 g/cm³ - 1 g/cm³)
= (0.9988 g/cm³ ÷ 0.18 g/cm³)
V'/V" = 5.55
Since V = V' + V"
V' = V - V"
(V - V")/V" = 5.55
V/V" - V"/V" = 5.55
V/V" - 1 = 5.55
V/V" = 5.55 + 1
V/V" = 6.55
V"/V = 1/6.55
V"/V = 0.153
So, the fish must inflate its air sacs to 0.153 of its expanded body volume
Answer: Option C) leaves
Explanation:
Autotrophs including green plants consists of cells that have chloroplasts, these chloroplasts possess a green coloured pigment called chlorophyll that are abundant in the leaves, and helps in receiving trapping sun light among other simple inorganic molecules like atmospheric carbon dioxide and water, necessary for the synthesis of sugar molecules during the process of photosynthesis.
Thus, the abundant presence of chlorophyll in leaves makes photosynthesis occur more in leaves
