Explanation:
The first creatures that evolved the first are fish. The first creatures they were evolved before amphibians,reptiles and mammals were fish.
What is the king organism of reptiles ?The king organism of reptiles category is crocodile.
Amphibians, reptiles, mammals and birds evolved after fish where the first amphibians that evolved from a lobe-finned fish ancestor about 365 million years ago. Fishes were the most earliest vertebrates to live on land but they had to return to water in order to reproduce.
The first vertebrates were therefore the fishes that had the different categories from chordates and vertebrates where few had the notochord and few had the vertebral columns.

how many trials did it take for half of the virtualium atoms to decay?
Answer:
Carbon-14 has a half-life of 5,730 years. Taking one atom of 14C, this will either have decayed after 5,730 years, or it will not. But if this experiment is repeated again and again, it will be seen that the atom decays within the half life 50% of the time.

Describe the pathway in a eukaryotic, somatic cell, from DNA to extracellularly secreted protein. Include detailed descriptions of each mechanism, process, location, molecules and potential outcome.
Answer: The pathway involves the transcription and translation processes.
Explanation:
The DNA present in the somatic cells of the eukaryotic organisms undergoes transcription in which the DNA is used as a template to form mRNA. It occurs in nucleus
The mRNA encodes for a amino acid chain for a specific protein in the process of translation. It occurs in cytoplasm and require a cell organelle called ribosome.
The amino acid sequence for different proteins are different.
why is freshwater beneficial to plants
Explanation:
freshwater beneficial to plants is because estuaries are usually shallow, sunlight can reach all levels of the water. Plants and algae are important to freshwater biomes because they provide oxygen through photosynthesis,
They enhance water quality and facilitate stop alga growth by victimisation nutrients created by fish waste, unconsumed food and organic scrap. They turn out element throughout daylight, that is employed by fish and helps stabilize pH scale. Fish, in turn, unleash unleash, that plants use as a food supply.

The mass of an element is the sum of the atomic number and the number of
A. electrons.
B. ions.
C. neutrons.
D. protons.
Answer:
a. electrons
Explanation:
The mass of an element is the sum of the atomic number and the number of protons.
What is atomic mass?Atomic mass is the total weight of all the particles (protons, neutrons, and electrons) in a single atom. It is expressed in atomic mass units (amu) or daltons (Da). The atomic mass of an element is determined by the number of protons and neutrons in the atomic nucleus.
Each proton and neutron has a mass of approximately 1 amu, and the atomic mass of an element is determined by the total number of these particles in the nucleus. The atomic mass of an element is unique and remains constant, regardless of the number of atoms of that element present. This value is important in determining the chemical properties of an element and the behavior of compounds and mixtures.

How does the burning of fossil fuels and deforestation contribute to the overall amount of carbon dioxide?
Answer:
Forests store large amounts of carbon. When fossil fuels are burned, carbon from dead and decayed plants, animals and phytoplankton that lived hundreds of millions of years ago (before dinosaurs existed), is released into the atmosphere in the form of carbon dioxide. .
To ensure that a human gene is translated properly in a bacterial cell, you should clone the _____________ for the gene instead of the genomic DNA fragment that contains the gene.
Answer:
complementary DNA (cDNA)
Explanation:
The complementary DNA (cDNA) is a region of DNA that is synthesized from an RNA template by using a reverse transcriptase enzyme. cDNA is usually used to clone genes from eukaryotic organisms in prokaryotes. cDNA cloning is a technique that consists of isolating and amplifying a self-replicating prokaryotic organism that includes in its genome a cDNA of interest. This technique enables the insertion of fragments of eukaryotic DNA (cDNA) into plasmids that subsequently are multiplied by cloning and finally sequenced.

Rust - An example of a common oxide mineral.
Native Element Minerals - Contains atoms of a single element.
Sulfate minerals - Contains the elements sulfur and oxygen.
Explanation:
I just took the test and its correct. Hope you make a good grade!
The minerals categories matched to their best description are :
Halide minerals: Minerals that contain elements that combine with chlorine, fluorine, bromine, or iodine.Rust: An example of a common oxide mineral.Native Element Minerals: Contains atoms of a single element.Sulfate minerals: Contains the elements sulfur and oxygen.What are minerals?A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement.
Halide minerals are those that combine with halogens. Rust is a common oxide mineral. Sulfate minerals consist of sulfur and oxygen. Native minerals (originally found) are those that consist of only toms of a single element in pure form.
Therefore, the minerals are matched with their correct description.

Answer:
lungs
explanation:
Asbestosis (as-bes-TOE-sis) is a chronic lung disease caused by inhaling asbestos fibers. Prolonged exposure to these fibers can cause lung tissue scarring and shortness of breath. Asbestosis symptoms can range from mild to severe, and usually don't appear until many years after continued exposure
Answer:
C.Asbestosis is long term inflammation and scarring of the lungs due to asbestos fibers. Symptoms may include shortness of breath, cough, wheezing, and chest tightness. Complications may include lung cancer, mesothelioma, and pulmonary heart disease. Asbestosis is caused by breathing in asbestos fibers.

The development of retinoblastoma is associated with a mutation in the 13q14.2 region of the human genome. What is the principle of indexing different parts of the genome?
Answer:
Genome indexing is a strategy to find a pattern (i.e., a short sequence read) in a long text (i.e., the genome)
Explanation:
Genome indexing is a similar strategy used when a book is indexed. This strategy is used to find more rapidly a given sequence by allowing to align the problem sequence and thus approximate to the putative origin of the query sequence within the genome. Genome indexing enables to design PCR primers/probes, map probes at genome level, understand data obtained from gene expression analyses, etc.
