Answer
After inland population after migration allele frequency is 0.62 or 62%
Explanation:
Given,
Coastal striped phenotype freq. = 0.22
ss = 0.22

= 0.22
Similarly, inland striped phenotype freq. = 0.43
= 0.43

=
= 0.4690
= 0.47 i.e. 47%

= 0.655
= 0.66 i.e. 66%
the migration range (m) is given as 20%
m= 0.2
allele freq. after migration = pre migration + ∆q
here,
∆q = change in the allele frequency
or
migration of allele freq. from coastal to inland
=
= 0.2 (0.47 – 0.66)
=
= - 0.0382
∆q = -0.04 i.e. 4%

When the blood conce
Explanation:
When the blood ca+ concentration falls below the standard of 4.4-4.5mg/dL,that is below 4.4mg/dL the clinical condition is called hypocalcemia. It is caused by hypothyroidism,due to malfunction of the parathyroid gland.
Generally, Ca+ is needed for contraction of muscles by causing the fusion of the vesicles containing neurotransmitters to the presynaptic membrane for the passage of neuro transmitters to fuse with the receptors on the sarcolemma to initiate muscular contractions by opening of ligand gated Na+. It also interact with the ligand gated sodium ion channels
Generally,Ca+ inhibits depolarization of ligand gated Na+ channels. Thus blocks the opening of these channels and therefore the rate of excitability.Therefore, If the is low serum levels of Ca+,There is increased in the threshold of depolarization because more ligand gated Na+ channels are opened,Thus their is increased excitability of nerves and muscles fibres therefore in the clinical manifestations listed above.
It can be treated with infusion of Ca+ into the blood.

Explanation:
Chloroplasts are composed of three membrane systems. Surrounding the organelle we can find the external membrane. To the interior of the organelle, there is the internal membrane. These two systems are separated by the intermembrane space. According to the endosymbiotic theory, the presence of a double membrane is the characteristic that reinforces the idea of a prokaryote being phagocyted by a eukaryote. The internal membrane looks identical to the membrane of bacterias, while the external membrane looks like the eukaryotic one.
Thylakoids are located in the interior of the organelle. These structures are also surrounded by a membrane, and in their interior, there is the thylakoid space. Each thylakoid looks like a hollow sac, and together with other thylakoids, they form piles, known as grana. Different piles or grana connect to each other by longer membranes. These internal structures together compose the third system of membranes. The photosynthetic pigments are located in the thylakoids, where it occurs the light-dependent reactions.
Surrounding the thylakoids there is a dense liquid called the stroma. Here takes a place the Calvin cycle.
The atomic number of hydrogen is 1 (count the protons). The atomic mass number of hydrogen is also one (there are no neutrons!). For carbon, the atomic number is 6, and the atomic mass number is 12 (6 protons plus 6 neutrons). Adding the two neutrons changes our atom.
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels.

Carbon moves from plants to animals. ...
Carbon moves from plants and animals to soils. ...
Carbon moves from living things to the atmosphere. ...
Carbon moves from fossil fuels to the atmosphere when fuels are burned. ...
Carbon moves from the atmosphere to the oceans.
