Explanation:
In simple terms, the term bipedalism refers to a term used to classify organisms that are equipped and use two legs or limp to walk, stand, jump or run.
One other nonprimate animal that is also a biped is the ostrich. When we compare the bipedalism of an ostrich with our (humans) bipedalism we discover that in terms of
Speed; an ostrich can move faster than an average human, reaching speeds of up to 70 km/h (43 mph).
limb length; its limb length can range from 10 to 16 feet (120 inches to 192 inches) which is far greater than the average length of an adult human's legs.
Which statement did Virchow's work add to the cell theory?
A. Cells contain genetic material that consists of DNA.
O B. The cell is the basic structural and functional unit of life.
O C. All living things are made of one or more cells.
O D. All cells come from other living cells.
Answer:
D
Explanation:
The German doctor Rudolf Virchow proposed that all cells result from the division of previously existing cells, and this idea became a key piece of modern cell theory.
This results from cytokinesis when he observes cells splitting into two.

There are three alleles for the ABO blood group in humans. Why are there only two alleles normally present in any individual?
1. The alleles for the ABO blood group always segregate independently during meiosis.
2. Each parent contributes only one allele for the ABO blood group to the offspring
3. Every gene for the ABO blood group must be recessive.
4. The alleles that determine the ABO blood group are on the X-chromosome.
Answer:
2. Each parent contributes only one allele for the ABO blood group to the offspring
Explanation:
Humans are diploid organisms, which means that our cells have two copies of the same gene. These copies are called alleles. We inherit one allele from each parent.
Just like most of our traits, we inherit our blood group from our parents. There are three alleles that determine our blood group: A, B, and O. We can get only two of them, though. Whether our blood group is A, B, AB, or O will depend on the combination of the alleles we inherited.
Can you please help me I am super stuck
Answer:
a.) 12 Newtons
b.) Same Direction
c.) Unbalanced
Explanation:
The system shows 2 individual forces:
A force of 5 N pulling the box LEFT
A force of 7N pushing the box LEFT
Both forces are LEFT, so they have the same direction.
Since the parallel forces both have the same direction, regardless of whether it's a push or pull or what side of the box the force acts upon, the resultant force will be the sum of the two forces in their direction:
Resultant force's magnitude is then: 5N + 7N = 12N
Resultant force's direction: unchanged = LEFT
Since the resultant force's magnitude is not 0, the system is unbalanced.

Answer:
A. An undifferentiated cell that has not yet been programmed and can become any type of cell = Stem cell
C. Traits that are influenced by more than one gene = Polygenic traits
F. Genetic engineering that exactly duplicates an organism = Reproductive cloning
G. Identical twins = Monozygotic twins
H. Making mRNA from DNA = Transcription
J. A change in the DNA sequence = Mutation
K. Fraternal twins = Dizygotic twins
L. Thirteen DNA sequences that all humans carry = Short tandem repeats
M. Traits that involve the actions of many genes but also interact with the environment = Quantitative traits
N. Uses ribose as the sugar in the nucleotide = Ribonucleic acid
Explanation:
Stem cells are undifferentiated cells that are capable of self-renewal or differentiation into many different types of cells. Polygenic traits are phenotypic traits influenced by two or more genes, while quantitative traits are phenotypic features controlled by the combined effects of many genes and environmental factors. Reproductive cloning is a laboratory technique used to produce genetically identical individuals from mature somatic cells. Monozygotic twins are identical twins obtained by fertilization of a single egg cell which then splits in two, while dizygotic twins are generated by fertilization of two different eggs. Transcription is the process where the genetic information contained in a strand of DNA is copied into a particular type of RNA (mRNA, tRNA, ncRNA, etc). A mutation is a genetic alteration in the DNA sequence of a cell of a living organism that is produced during DNA replication. Short tandem repeats (STRs) are repeated DNA sequences (2-16 nucleotides, two or more times) that are adjacent to each other. In humans, there are 13 well-characterized STR sequences known to be associated with populations of different ethnic groups.

Rocks and minerals activity Reflection questions:
1. Describe the ways mining in the real world can affect society, ecosystems, and the environment of a specific region.
2. Using your answers to the question above, list the criteria you believe should be addressed by land reclamation. Prioritize your criteria by order of importance. Explain the order you selected for your criteria.
3. Complete redamation of mined land is the solution you practiced in this cookie mining lab. What reasoning supports this solution as one that will provide the largest benefits and least costs to society and the environment ?
4. Legislation requiring the reclamation of the land makes mining more expensive. How important is this constraint to achieving complete reclamation of mined land?
Answer:
1. Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local.. 2.Mining in the real world can affect society, ecosystems, and the environment of a specific region because all the minerals that you are looking for won't be right where you want them to be. It is not going to be in the same area. Instead, it will be scattered throughout the mines and you will have to search for them. 3.Students act as mining engineers and simulate ore mining production by using chocolate chip cookies. They focus on the cost-benefit analysis of the chocolate ore production throughout the simulation, which helps them understand the cost of production. As students “mine” with tools such as paperclips and toothpicks, they keep records of their costs—land (cookie), equipment used, cookie size before and after production, and time spent. While the goal is to make as much profit as possible, other costs and goals are taken into consideration—as in real-world mining engineering. For example, mining engineers also consider the resulting amount of destruction to the lithosphere when deciding the best method to obtain ore. Thus, a line item for land reclamation cost is included from the beginning. A provided worksheet serves as a profit and loss statement. 4.Mine reclamation is the process of restoring land that has been mined to a natural or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started.
Explanation:
i don't have a explanation but i hope this helps
The extraction of minerals or other geological elements from the earth is known as mining.
How does mining affect society, ecosystems, and the environment?Society: Mining increases social conflicts, causes relocation of the community, affects the health of humans and animals and causes loss of land. However, it helps increase economic growth. Ecosystem: Mining adversely affects biodiversity and destroys the habitat.Environment: Mining causes erosion, sinkholes, deforestation, overuse of water resources, waste disposal issues, acidification of soils and water bodies, and their contamination.What is land reclamation?It is the process by which the mined lands are filled, thereby producing land that can be used. They can be used to restore the environment. However, the ecosystem and society's restoration takes a long time.
Is it beneficial?While the land that cannot be used now has been restored, the materials that have been used have been taken from a source, and that can lead to changes in the ecosystem at the source.
What is the reasoning that supports land reclamation as the solution?The goal is to produce as much profit as feasible. When determining the optimum approach to collecting ore, mining engineers, take into account the amount of lithosphere destruction, and hence, from the start, land reclamation costs are included.
What is the role of mine reclamation legislation?It ensures that land reclamation activities are planned before a mine is licensed or started.

C. Electrons flow from an outlet into a toaster, causing it to heat a

D. A person rubs a shoe on a rug, causing extra electrons to be
transferred to the shoe.
Answer:
The correct example of current electricity is C. Electrons flow from an outlet into a toaster, causing it to heat a slice of bread.
Explanation:
Current electricity refers to the flux of charged particles through a conductor material per unit of time. In general, when we refer to electric current we are talking about the electron flux. Electric energy originates from the difference of electrical potential between two points when they get in contact through a conductor. This contact provokes an electrical current that consists of the transmission of negative charges called electrons through conductor materials such as metals from the source of generation to the point of consumption.
In the exposed example, the source of electrons is the outlet, while the point of electron consumption is the toaster. In this last artifact, electrical energy is transformed into heat to toast the bread.

CELL DIVISION:
Cell division involves two processes namely: mitosis and meiosis. Mitosis results in two daughter cells that are genetically identical to one another. Meiosis, on the other hand, results in four daughter cells that are genetically different from one another. Mitosis and meiosis as types of cell divisions involves phases namely: prophase, metaphase, anaphase and telophase. The major difference between prophase of mitosis and prophase I of meiosis is that homologous chromosomes, which are similar but non-identical chromosomes from each parent, are paired.Learn more about prophase of mitosis and meiosis at: https://brainly.com/question/23718222?referrer=searchResults
