How does a universal genetic code relate to the hypotheses about the origin of life on earth

Biology
1 answer:
Vikentia [17]3 years ago
7 0
The referenced universal genetic code is understood to be DNA. Its multilevel coded intelligent design structure is a complex information system more complex than anything else in the universe and considerably more complex than anything humans have ever produced. The DNA structure is comprised of homochiral amino acids and pentose sugars that cannot be created through any naturalistic processes.

It is estimated that the the simplest organism is comprised of 600-1500 gene products, requiring >1 million nucleotides to properly decode and produce the proteins, RNA, enzymes and ribosomes that the cell is structured of.

Abiogenesis, the naturalistic hypothesis for the origin of life, has no explanation for the origin of life processes required to produce life. The intelligent designed DNA is proof of the existence of God, the creator of the universe and life.

On ten acres of native forest there are eight white-tailed deer, seven coyotes, 45 armadillos, and 231 loblolly pine trees. Whic
Natasha2012 [34]

loblolly pine trees

Explanation:

Population density refers to the amount of organisms living in a particular area:

            Population density = \frac{number of organisms}{Area}

Area of the forest = 10acres

Population densities of:

  White-tailed deer = \frac{8 white tailed deer}{10acres}

                                 = 0.8white tailed deer/acres

   Coyotes = \frac{7 coyotes}{10acres}= 0.7coyotes/acres

   Armadillos = \frac{45 armadillos}{10acres} = 4.5armadillos/acres

   loblolly pine = \frac{231loblolly pine trees}{10acres} = 23.1loblolly pine trees/acre

The population with the highest density is that of the loblolly pine trees with 23.1 of the trees in an acre.

G protein‑coupled receptors (GPCRs) and receptor tyrosine kinases (RTKs) are two basic receptor types by which cells transduce s
weqwewe [10]
<h2>GPCRs and RTKs</h2>

Explanation:

1) Phosphorylation of receptor can terminate signal or desensitize receptor: GPCRs because when signal persists a protein kinase receptor is activated,this further catalyse the phosphorylation of several serine residue at cytosolic phase of 7 transmembrane

Phosphorylated transmembrane recognized by arrestin protein blocks interaction between trimeric G protein and receptor thus blocks signal transduction

2) Autophosphorylation of receptor can initiate signal: RTKs because receptor dimerization activates intrinsic tyrosine kinase activity by which they phosphorylate its own tyrosine residue on cytosolic phase

3) Structure contains seven transmembrane helices: GPCRs because it consists of single polypeptide and spans the membrane 7 times hence called 7 transmembrane;it recognizes external signal and activates trimeric G protein

4) Ligand binding induces conformational change in receptor: RTKs because normally RTK exist in monomeric form in absence of any ligand molecule but when any ligand molecule binds receptor starts to dimerize

5) Receptor activation causes phosphorylation of its cytosolic subunits: RTKs because when receptor gets activates the intrinsic tyrosine kinase activity by which they phosphorylate its cytosolic subunits

6) An example is the insulin receptor: Insulin receptor is present on plasma membrane and belongs to RTK family and always exist in dimeric form

7) Transports some ligands through the membrane: Neither GPCR nor RTK;ligand gets transported through the membrane through ligand gated channel

8) An example is the epinephrine receptor: Epinephrine is an endocrine  hormone produced by adrenal glands in stress condition and prepare body for fight and flight;Epinephrine uses GPCR signalling pathway by four different types of membrane receptors in different tissues

9) Activate heterotrimeric G proteins directly: Transmembrane protein of GPCR recognizes the external signal and activates G protein,activated G protein binds with effector enzyme and activate it which further produce or destroy secondary messenger that carry message from cell surface to cell interior

Earth's early atmosphere was primarily composed of
Paul [167]

Answer:

The correct answer is ''carbon dioxide, water vapor and nitrogen.''

Explanation:

About 4.5 billion years ago, Earth was a very geologically active planet. So many volcanic fumes formed the primitive atmosphere, which was mostly made up of water vapor, carbon dioxide, sulfur, and nitrogen. At this point, oxygen was barely present and the oceans did not yet exist. The primitive atmosphere is the one before the Precambrian, it was reductive, that is, it lacked free oxygen, and only had ammonia, methane and hydrogen, the high temperature of the atmosphere in its early stages facilitated the reaction of these gases to form organic compounds from which life may have emerged. UV rays passed, because ozone did not exist.
