Suppose you want to know what the temperature of the universe was 1 billion years ago. Where along the horizontal axis should you look?.
Answers
We should almost entirely focus on the far right along the horizontal axis, once we knew about the temperature of the universe, 1 billion years ago.
The term "universe" (from the Latin "universus") refers to the entirety of space, time, and all of its objects, including galaxies, planets, stars, and other types of matter and energy.
The term "universe" refers to the entirety of existence, particularly all physical substance, such as all the stars, planets, galaxies, etc.
The Big Bang, an explosion of space, marked the beginning of our cosmos. Space expanded, the cosmos cooled, and the basic elements emerged from a very high density and temperature starting point. The first stars and galaxies were created as a result of the slow gathering of stuff by gravity.
The temperature of the universe was recently measured most precisely by the Cosmic Background Explorer spacecraft, which found it to be 2.726 0.01 kelvin.

A substitution mutation occurred and changed the 5th base in the DNA from a C to a T. Write the sequence of RNA codons that would result from this kind of mutation. **Separate each codon with a space. TACACGCAATTACCAGGGTAGCCATTGATT
Answers
The sequence of RNA codons resulting from the substitution mutation that changed the 5th base in the DNA from a C to a T is AUGUGCGUUAUCCAGGGUAGCCAAUUGA.
In DNA, the base C (cytosine) pairs with G (guanine), while in RNA, the base C pairs with G. However, due to the substitution mutation, the original C is replaced by a T (thymine) in the DNA sequence.
In RNA, thymine is replaced by uracil (U). Therefore, the RNA codons corresponding to the mutated DNA sequence can be derived by replacing each T with U and maintaining the sequence order.
The original DNA sequence TACACGCAATTACCAGGGTAGCCATTGATT would have the corresponding RNA codons AUGUGCGUUAUCCAGGGUAGCCAAUUGA. Each codon consists of three bases and represents a specific amino acid or a start or stop signal in the translation process of protein synthesis.
It's important to note that the given DNA sequence is provided as a single continuous string, and without additional information about the reading frame or specific gene sequence, it is not possible to determine the precise protein sequence or the functional implications of the mutation.

What is DNA?DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

describe how a plant takes in carbon dioxide from the air and mineral ions from the soil
Answers
Answer:
Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
Plants take in carbon dioxide from the air through their leaves and mineral ions through their root hairs
Plants take in carbon-dioxide through the atmosphere during photosynthesis in the presence of sunlight and gives out oxygen to the atmosphere in the process as well. while the mineral ions found in the soil are absorbed by a plant through its root hairs in the form of ions dissolved in water ( solutes ). these solutes are deposited in ground water by the humus soils which enables the absorption of the mineral ions by the plants.
Hence we can conclude that plants take in carbon dioxide from the air through their leaves and mineral ions through their root hairs.

Compare the sugar-phosphate arrangement in the backbone of the DNA from the plant, the manmal and the bacterium. Are there any differences?
Answers
Answer:
No, there are no differences
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two polynucleotide chains that interact together in order to form a double helix. This molecule (DNA) carries the genetic instructions that make each species unique. In DNA, each polynucleotide chain is composed of nucleotide monomers: a nucleotide is composed of a deoxyribose sugar attached to a phosphate group and one nitrogen-containing base (i.e., adenine, thymine, guanine and cytosine). This basic structure is the same among different species, and, therefore, genetic differences between different groups (in this case, animals, plants, and bacteria) are caused by differences in the nucleotide-base sequences of their DNA molecules.

the aggregation formed by antibodies binding cellular antigens or large particles is called
Answers
The aggregation formed by antibodies binding to cellular antigens or large particles is called immune complex.
An immune complex is a structure that forms when antibodies (produced by the immune system in response to foreign substances) bind to cellular antigens (molecules on the surface of cells or large particles that the immune system recognizes as foreign). This binding of antibodies to antigens results in the formation of an immune complex, which helps to neutralize and eliminate the foreign substance from the body.
When antibodies encounter antigens on the surface of cells or large particles, they can bind to them, leading to the formation of immune complexes. These immune complexes are composed of multiple antibody molecules bound to the antigens they recognize. This binding triggers a series of immune responses, including the activation of complement proteins and the recruitment of immune cells to the site of immune complex formation. Immune complexes can be found in various diseases, such as autoimmune disorders and certain infections. Their presence can contribute to tissue damage and inflammation, as well as play a role in the pathogenesis of immune-related disorders.

Explanation:
These scientists group the found fossil with birds on the basis of physical structures because first the scientists relate the fossil to the feathers of the bird and later the scientists relate it to the bone structure to determine the resemblance between the birds and the fossil of an obscure group of small dinosaurs so we can conclude that the scientists observe the found fossil on the basis of physiological characteristics of that fossil.
write a paragraph that describes where DNA is found inside cells and how it is packaged. If desired, add a drawing to support your paragraph. Underline each of the following terms at least once as you use it: Eukaryotic Cells, Prokaryotic Cells, Organelles, Nucleus, Nucleotides, DNA, Histones, Chromosomes And he said use all of terms for the paragraph and this is for biomedical science pltw and use your own words too please
Answers
Explanation:
DNA (Deoxyribonucleic acid) is the repository of genetic information in living things. It is biological macromolecule made up of several units called nucleotides. In Eukaryotic cells (organisms with membrane-bound nucleus), the DNA is found in the nucleus. This is however different in prokaryotic cells, as the DNA is found in a nucleus-like body in the cytosol called the nucleoid. In Eukaryotes DNA is ordered and packed by structural proteins called histones. A histone is a protein that provides structural support to a chromosome. In order for very long DNA molecules to fit into the cell nucleus, they wrap around complexes of histone proteins, giving the chromosome a more compact shape.
The DNA storages the genetic information. It is made of nucleotides that combine in different ways forming sequences that store specific information. In Prokaryotic cells, as there is not a nucleus, the DNA is on the cytosol in an area known as the nucleoid. On the other hand, in Eukaryotic cells, the DNA is separated from the rest of the organelles. It is in the nucleus surrounded by a membrane. For the DNA to fit in the nucleus, it has to be packed. Histones, which are proteins, wrap the DNA chains around them. As a result, they give support to a DNA molecule, also known as chromosomes.
The terms used in the paragraph refer to how DNA is in relation to other elements and according to the cell in which they are:
Eukaryotic cells: They are cells that have organelles and different compartments.Procaryotic cells: they are cells that do not have different compartments. The DNA is in the cytosol. An example of these types of cells is bacteria.Organelles: the different elements that a Eukaryotic cell has. Each has a function.Nucleus: the place in the Eukarityc cell that contains the DNA.Nucleotides: it is one of the components of DNA.Histones: Proteins that compact the DNA in order for it to fit in the nucleus.DNA: desoxyribonucleic acid, a molecule that contains genetic information.Chromosome: a molecule of DNA.All in all, after knowing what each concept means, we can relate them in a paragraph.
