Answer:
Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection)
Explanation:
Which type of bleed would typically be more urgent to treat—venous or arterial?
Answer:
Arterial bleeding is more dangerous than venous bleeding. The arteries carry blood from the body and back into the heart. If the arteries become damaged and start to bleed out, an individual can suffer loss of life within five minutes if the bleeding is severe and if no medical attention is received.

Answer: Identify the promoter and the stop signal (terminator).
Explanation:
DNA is a molecule that contains the genetic information in all living things. This information is used for the synthesis of proteins that make up the body and carry out vital functions of the organism.
The DNA molecule consists of two strands that wind around each other to form a double helix structure, where each strand has a central part formed by sugars (deoxyribose in the case of DNA) and phosphate groups. The four basic components of DNA are nucleotides: adenine (A), thymine (T), guanine (G) and cytosine (C). The nucleotides are joined together (A to T and G to C) by chemical bonds and form base pairs that connect the two strands of DNA. Depending on the sequence of nucleotides (which have different bases), different proteins are synthesized.
DNA replication consists of synthesizing another identical DNA molecule, using enzymes called polymerases, which are molecules specifically dedicated only to copy DNA. Transcription, on the other hand, is the process by which a copy of messenger RNA (mRNA) is generated from the sequence of a gene in the DNA. This RNA molecule leaves the cell nucleus and enters the cytoplasm, where it directs protein synthesis (a polymer made up of many amino acids).
Protein synthesis, or translation, involves translating the sequence of an mRNA molecule into an amino acid sequence during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding sequence of amino acids it encodes. To begin translation, a start codon (set of 3 bases) must first be identified, which is usually AUG that also codes for the amino acid methionine. Then, the codons that follow are read and the corresponding amino acids are added according to the genetic code. The transfer RNA (tRNA) is complementary to the anticodon at specific codons in the messenger RNA and carries the amino acid coding for the codon. In addition, ribosomal RNA (rRNA) is an RNA that is part of ribosomes and is essential for protein synthesis in all living things. rRNAs form the framework of ribosomes and associate with specific proteins to form ribosomal pre-subunits. To finish the translation, a termination codon has to be read, which can be UGA, UAG or UAA.
To revise the model to show transcription to form mRNA, the research should identify the promoter and the stop signal. The promoter is a DNA sequence required to turn a gene on or off. The transcription process starts at the promoter which is usually located near the beginning of a gene and has a binding site for the enzyme that is used to make a messenger RNA (mRNA) molecule. The enzyme RNA polymerase will keep doing the transcription until it reaches a sequence of DNA that is signal which indicates it should stop. This process is called termination, and it happens once the enzyme reaches this sequence, called terminator.
how do radiation, conduction, and convection affect the atmosphere?
Answer:
Conduction, radiation and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere.

If your cells couldn't go through meiosis- how could this affect you?
Answer:
An organism would not be able to reproduce without meiosis.
Explanation:
Between meiosis and mitosis, meiosis is by far not as important. If you are a asexual organism, this would be NOT IMPORTANT whatsoever. If you are a sexual organism, this would LARGLY effect you. But on a world scale, this is NOT AS IMPORTANT.
This is because, without mitosis, you could not heal and would die much much younger since your cells could not be replaced. On the other hand, without meiosis, any organism that reproduces sexually would be unable to do so, which could lead to extinction in many, many species. This would not be harmful, however, to species that can also or mainly reporuduce asexually through budding, fragmenting, or sporing. So overall:
Organisms that produce sexually would go extinct.
This is the only real affect I can think of. Since meiosis does not produce any cells aside from reproductive cells. And asexual organisms produce reproductive cells through other means.

Explanation:
In a sample of double stranded dna if 27% of the nitrogenous bases are thymine what percentage of nitrogenous bases are cytosine?
Answer:
73%
Explanation:
Given: 27%
To find: Percentage of nitrogenous bases are cytosine
Solve: [tex]\frac{27}{100}[/tex] × [tex]\frac{100}{1}[/tex]
Firstly, divide 100% by thymine and cytosine
[tex]\frac{100}{2}[/tex] = 50
Now, If it is 50 / 50, but thymine has 27 then subtract 27 from 100
100 - 27 = 73
So, the percentage of nitrogenous bases are cytosine 73%
Identify how information for specifying the traits of an organism is carried in the DNA.
Answer: DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).
Explanation:
The traits or characters are present in the DNA in the form of genes. Genes are short stretches of nucleotides present in DNA and represent the encoded message that is present in the individual.
What is a gene?Genes are present in the DNA. It carries information about the traits that are expressed in an individual. Genes come from parents to offspring, so they are hereditary and pass from one generation to the next. From DNA, mRNA is formed from the gene by the process of transcription.
This mRNA is again converted to proteins or polypeptides by the process of translation. This product is the result of the message that is present in the gene. Example: melanin pigment and skin color variation. As different persons have variations in their genes, the production of this melanin protein synthesis varies, and as a result, skin color among individuals varies.
Hence, the information for specifying the traits is carried by genes present in DNA.

Autosomal Recessive
Explanation:
The method of inheritance is autosomal recessive. Notice how the disease skips the parent generation. This indicates that parents have the recessive allele but do not express the trait. The individuals who are shaded in have two recessive alleles that were passed on from their parents, therefore they have the disorder.

Why are archaea in a different domain from bacteria?
A. They are multicellular, but bacteria are unicellular.
B. They are thought to have separate paths of evolutionary
development
C. They are able to perform endosymbiosis, but bacteria are not.
D. They have no similar characteristics.
Answer:B
Explanation:
Archaea is in a different domain from bacteria because they are thought to have separate paths of evolutionary development. Therefore, the correct statement is option B.
What are the differences between archaea and bacteria domains?Archaea and bacteria are both prokaryotic organisms, but archaea are more closely related to eukaryotes than bacteria. Archaea have unique lipid membrane and cell wall components that are different in composition than those found in bacteria.
These differences suggest that archaea and bacteria evolved to have separate paths of evolutionary development early in the history of life on Earth and then classified into Archaea and Bacteria domains.
Based on the phylogenetic tree constructed by researchers, the tree has classified life into three domains which are Archaea, Bacteria, and Eukarya These domains are based on their fundamental genetic and biochemical differences.
Therefore, archaea and bacteria are in a different domain because they followed separate paths of evolutionary development.
