A new born has soft spot on he top of its head. This is called as fontanelle and is diamond in shape present on the top of the head of the baby.

Babies skull is very soft and can be very easily moulded, to help them squeeze through the birth canal at the time of delivery.

Moulding is done in the skull of the babies as it is most largest part of the body during the time of delivery.

As soon as the skull and bones of the baby meet and fuse they become hard gradually.

kobusy [5.1K]

Answer:

The product of glycolysis is two molecules of pyruvate. It is a three-carbon compound. This pyruvate again undergoes oxidation in the cytoplasm. This process is called pyruvate oxidation which produces Acetyl CoA. The Acetyl CoA is a two-carbon molecule.

Acetyl CoA again used for the citric acid cycle. This is also called as Kreb's cycle / TCA cycle. Because citric acid has 3 carboxylic groups. The acetyl coenzyme produces NADH, FADH2, ATP. The citric acid cycle occurs in the mitochondrial membrane. This is an 8 step process. The first product is citric acid. The other products of each step are isocitrate, alpha-ketoglutarate, succinyl CoA, succinate, Fumarate, L - malate, and Oxaloacetate (OAA).

Another process of aerobic respiration is the electron transport chain ( ETS). Here the energy stored in NADH, FADH2 in the citric acid cycle are utilized. It is a chain of electron carriers. ETS occurs in the inner membrane of mitochondria.  

In short, the glucose splits by glycolysis and produces ATP, NADPH, and final product pyruvate. The pyruvate is oxidized and forms acetyle coenzyme. This is used in the TCA / citric acid cycle. In this process also NADH, FADH2 which forms electrons are produced. Theses electrons are carried by different electron carriers and accepted by oxygen.

In the process of pyruvate oxidation 6 ATP, and in Kreb's cycle 18 ATPs, in ETS, 4 ATPs are produced. In addition to this in glycolysis produces 4 ATPs. The total number of ATP in aerobic respiration is 32 ATP.

If the pinsulin receptor, a, example of an integral membrane protein, is cotranslationally inserted into the ER membrane with th
kicyunya [14]

Answer:

The correct answer is option C.

Explanation:

As the proteins are produced in the endoplasmic reticulum membrane, they amalgamate with the vesicles and then they are conducted towards the membrane's cell surface where they act as an integral membrane protein.  

The outer end will bind with the ligand and the other one will get attached towards the cytoplasm. Thus, the pinsulin in the given case will combine with the C terminus of the protein.

Some people see wind energy as a clean alternative to fossil fuels. Others believe that utilizing this renewable energy resource
Y_Kistochka [10]

Answer:

Renewable energy resource as an obstacles for the growth of migratory salmon populations: It is now believed that the reduce access to spawning grounds and nursery areas, leading to a decrease in migratory fish populations is due to the dam structures of large storage-type schemes, which can create great obstacles for the movement of migratory fish species.

Explanation:

  • Storage-type schemes ( big dams) can significantly change the downstream flow regime,and may also alter water temperature and quality, and even make it inhabitable for fish to live.
  • As the storage of water can be linked with high evaporative losses, which in turn results in high life cycle water footprints compared to other sources of electricity.

<u>Run-of-river (ROR) schemes are HEP schemes: </u>

They operate without water storage, using the flow within a river channel.They are ecologically friendly and do not disturb the natural mechanism for the migrating salmons.

Working Principle:

They are normally used to regulate water levels, which allows a proportion or part of flow to be diverted down a secondary channel to a turbine before it is returned to the main channel further downstream.

There are some modern turbine types used in ROR HEP(hydroelectric power) schemes, which are also designed to allow fish to pass through the system unharmed if the fish do pass through the intake screens.

PLEASE HELP!! <br><br> How is a karyotype useful?
Firlakuza [10]
Karyotyping can be used to detect a variety of genetic disorders. For example, a woman who has premature ovarian failure may have a chromosomal defect that karyotyping can pinpoint. The test is also useful for identifying the Philadelphia chromosome. Hope this helps :)
