Why can't a hair shaft be used to collect an individual's DNA
Answer:
A hair w/out the follicle and its nuclear DNA, or genetic material in its nucleus, cannot provide individual evidence. Physical examination of the hair can only yield class evidence.
Explanation:
Answer: Hope this helps!
Explanation:
When performing a hair DNA test for the purpose of paternity, it is a must to have a complete hair sample – with hair shaft and hair follicle. On the other hand, if the purpose of hair DNA testing is for forensic use, a cut hair sample even with no follicle can still be of use. However, a complex procedure has to be made.

How can extinctions and expansions occur in the same habitat? Explain your answer.
When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time.
Extinctions are associated with biodiversity changes, thereby affecting species expansion.
What is extinction?Extinction refers to the disappearance of a given taxonomic group (e.g. species-level extinction).
This process of disappearance (extinction) modifies the trophic relationships in the ecosystem.The modification may lead to the expansion of a given species (e.g., prey in the case of predator extinction).In conclusion, extinctions are associated with biodiversity changes, thereby affecting species expansion.

An ecological footprint A) is a means of determining increases in populations that lived in the past. B) is a means of understanding resource availability and usage. C) measures dispersion and adaptability. D) will estimate population movements.
Answer: An ecological footprint is a means of understanding resource availability and usage. The correct option is B.
Explanation:
The ecological footprint is a method which is used to measure the rate as which humans use natural resources in their environment and generate waste from them compared with how fast nature can absorb these wastes and generate the used resources again. The productive areas which are measured through this means are:
--> cropland,
--> grazing land,
--> fishing grounds,
--> built-up land,
--> forest area, and carbon demand on land.
The importance of ecological footprint to the environment should no the over emphasizes. When properly observed, different environmental pollution would be dealt with. Generally, there would be:
--> decreased desertification,
--> decreased global warming
--> availability of fresh unpolluted air and
--> decreased carbon emissions.

A.physical protection of internal organs from disease-causing organisms B.filtration of disease-causing organisms from the body C.production of white blood cells that can destroy disease-causing organisms
D.storage of calcium that makes bones stronger and less prone to attack from disease-causing organisms
The correct answer is C.production of white blood cells that can destroy disease-causing organisms as it protects the body against infection.
White blood cells guard your frame in opposition to contamination. As your white blood cells tour thru your bloodstream and tissues, they find the contamination and act as a military widespread to inform different white blood cells in their region to assist shield your frame from an assault of an unknown organism.
How are white blood cells produced in the skeletal system?White blood cells start withinside the bone marrow in a manner referred to as hematopoiesis. All blood cells descend from a not unusual place hematopoietic stem cell (HSC). This is likewise referred to as a "pluripotent" stem cell.

Scenario Questions Read the following scenario to answer the following questions. Birds are a widespread group of animals with approximately 10,000 different species found throughout the world today. Because they are relatively easy to find and so visually appealing, they have been studied more thoroughly than many other groups of animals. They are also valuable biological indicators because many species live in different habitats during different times of the year and cover long migration routes. According to the World Conservation Union, extinction threatens over 1,200 bird species today, and at least 179 are critically endangered. Some of the most endangered species include the Tahiti monarch, with only 10 pairs remaining, and the Bali starling, with only 12 wild individuals left. In Hawaii, the last captive po'ouli died in 2005, and the last two known to be alive in the wild have not been seen since 2003-2004. Common birds are also disappearing. In North America, red-winged blackbird populations declined by at least 1 percent each year between 1980 and 1999. These examples can serve as a warning. Habitat loss through destruction, degradation, and fragmentation are serious problems that affect 86 percent of threatened birds and are exacerbated by unsustainable forestry practices and intensifying agriculture. All of this shows that conservation of habitats is critical if many of the world's bird species are going to be saved from extinction in the near future.
What is the greatest threat to birds today?
A) pollution
B) poaching
C) habitat loss
D) the illegal pet trade
Answer: C) habitat loss
Explanation:
There are over 1,200 birds threatened with extinction and of this number, 86% are classified as such because they lost their habitats. That means that habitat loss is overwhelmingly the biggest challenge facing birds today.
The habitat loss is mostly as a result of human actions such as deforestation and land degradation stemming from unsustainable forestry and agricultural practices. For instance (not in excerpt), the Amazon rainforest which is home to a lot of birds is being destroyed at an alarming rate and the clearing of forests in developing countries for settlement are some examples of human actions leading to habitat loss.
C) habitat loss
The greatest threat to birds and the common denominator of biodiversity loss is the destruction and degradation of habitats. Habitat loss includes fragmentation, destruction, and alteration of the natural areas that birds need to complete their annual or seasonal cycle

Explanation:
The human body is arranged into a hierarchical organization, starting from a single cell to a complete organism.
Answer: Subatomical particles, atom, molecules, organelles, cells, tissues, organs, systems, organisms.
Explanation:
The biological organization is the hierarchy of complex biological structures and systems using a reductionist approach. Each level in the hierarchy represents an increase in the complexity of organization, each "object" being composed of basic units of the previous level but the properties and functions found at a given hierarchical level are not present at lower levels.
The hierarchy is classified into a first level (chemical level) made up of subatomical particles, atoms, molecules and macromolecules. And a second level (biological level) made up of organelles, cells, tissue, organs, and systems.
The first of the levels of organization, the chemical level, of living beings describes the most primitive factors, but which constitute the basis for the conformation of the following levels. In this level we have abiotic factors such as atoms, which are some of the smallest constituents of the chemical components, but which in turn from the union of several of these atoms give rise to what is known as molecules. From the union of the basic biomolecules are created larger compounds called inorganic and organic biomolecules. In the inorganic ones we find simple molecules such as water and mineral salts. And in the organic ones, which are exclusive of living beings, there are macromolecules such as proteins, lipids, glucides and nucleic acids. These macromolecules in turn will form essential elements for biological life such as structures and organelles (cell wall, membranes, ribosomes), which will be fundamental at the next level.
The second level of organization of living beings is the biological level, constituted by biotic factors, starting with the most basic steps such as the conformation of the cell and its organelles. The biomolecules that constitute the biological beings, also undergo a small classification that allows us to visualize how the union of several molecules are integrating molecules with increasing complexity.
Firstly, the grouping of these cells form tissues, these tissues are characterized by the fact that they are formed by thousands of cells that come from the same origin and also perform the same function. Examples of these tissues are epithelial tissue, bone, and others. The union at the tissue level can form organs, whose purpose is to perform a specific activity and which is essential for survival (for example, kidney, heart, liver) The next level is the systems, an organization of multicellular organisms based on the fact that some organs that are constituted by the same tissues, perform particular and different functions (for example skeletal system or muscular system) At last, we have organisms which are functional grouping of systems.
So, a summary of the hierarchical organization is:
Subatomical particles: Protons, neutrons and electronsAtom: Structure in which matter is organized in the physical world or in nature, composed of subatomical particles.Molecules: Group of atoms.Organelles: Subunit of the cell related to a certain cellular function. For example, a mitochondrion, the main site of ATP generation in eukaryotes.Cells: Basic unit of life and a grouping of organelles, the smallest structural unit of living things capable of functioning independently. Eukaryotic cells can unite to form multicellular organisms which have a higher level of organization.Tissues: Functional grouping of cells in multicellular organisms.Organs: Functional grouping of living tissues, a group of cells that perform a certain function. For example, cardiac muscle tissue. Systema: Functional grouping of organs that are organized to perform a certain function. For example, the circulatory system.Organisms: Basic life system, a functional grouping of lower components with at least one cell. For example, a plant or an animal.✧･ﾟ: *✧･ﾟ:* hello *:･ﾟ✧*:･ﾟ✧

The E-site A) is found on the RNA polymerase enzyme. B) is responsible for the release of the tRNA. C) is found on the 35S polysome. D) is the aminoacyl site on the ribosome. E) is another name for anticodon.
Answer:
B) is responsible for the release of the tRNA.
Explanation:
A transfer ribonucleic acid (tRNA) is an RNA molecule that connects a particular triplet of nucleotides or 'codon' of a messenger RNA (mRNA) to a particular amino acid during protein synthesis (translation) in the ribosomes. In a cell, tRNAs can be found in three different forms: aminoacyl-tRNAs, peptidyl-tRNAs, or deacylated tRNAs. Moreover, during translation, the tRNA binds to the ribosome at three different sites. The E-site (E for exit) refers to the final binding site for deacylated tRNAs in the ribosomes (i.e., before their dissociation from the ribosomes) during protein synthesis. The first binding site for tRNA in the ribosome is the A-site (A for aminoacyl), while the second binding site is called P-site (P for peptidyl). These three sites are oriented in inverse sense (5' to 3' E-P-A) with respect to the mRNA.

Two completely new strands of DNA built from the lagging strand
Two strands of DNA that are joined, running antiparallel
Two strands of DNA that each contain one strand of the original DNA molecule
The immediate result after DNA replication during meiosis is two strands of DNA that each contain one strand of the original DNA molecule.
Meiosis is a reductional cell division by which a cell produces four daughter cells with half of the chromosomes.
Meiosis is preceded by a stage called interphase in which DNA is replicated. The phase of the interphase in which genetic material is duplicated is known as Synthesis (S) phase.
During DNA replication, a new DNA molecule consists of one original DNA strand bound to one strand of newly synthesized DNA.
It is for that reason that DNA replication is said to be semiconservative.
In conclusion, the immediate result after DNA replication during meiosis is two strands of DNA that each contain one strand of the original DNA molecule.
