He was able to detect increased concentrations of carbon-14 in the goats' lipids, proteins, carbohydrates, and DNA
Answers
Answer:
See the answer below
Explanation:
A researcher performed an experiment in which he exposed young corn plants to a harmless, radioactive form of carbon dioxide gas containing carbon-14 instead of carbon-12. he then began feeding corn produced by the plants to a small group of goats. after several weeks, the researcher took blood and tissue samples from the goats. he was able to detect increased concentrations of carbon-14 in the goats' lipids, proteins, carbohydrates, and dna. which statement best explains the researcher's findings?
a. uptake of radioactive carbon dioxide gas caused carbon atoms to be found in places they wouldn't normally be found.
b. carbon atoms found in the sugar molecules of the corn were used by the goats' bodies to form other large molecules.
c. like the corn plants, the goats experienced prolonged exposure to carbon dioxide gas containing carbon-14.
d. eating corn containing radioactive carbon-14 caused many of the goats' other carbon atoms to become radioactive.
The correct answer here would be that the carbon atoms found in the sugar molecules of the corn were used by the goats' bodies to form other large molecules.
This is usually what happens when organisms feed on nutrient-containing substances. The nutrients are extracted during digestion and are utilized in the anabolic processing of important biomolecules in the body of the organism.
Carbon is an important element in all biomolecules of life such as lipids, proteins, nucleic acids, etc. and as such, the carbon present in the corn consumed by the goats must have been used to form some of these molecules in the bodies of the goats.

Based on the data, what is the probability a randomly chosen cell will be observed undergoing cell division? You may use the calculator. A.15% A. 15% B.18% B. 18% C.30% C. 30% D.85% D. 85%
Answers
Answer:
A
Explanation:
The active state of cell division covers the prophase, metaphase, anaphase, and telophase. The total number of observed cells that were undergoing cell division can, thus, be calculated by adding the number of cells in each stage of the cell division.
Total number of cell in division = 20+4+2+4
= 30
Probability that a randomly chose cell will be undergoing cell division = number of cells in division/total number of cells
= 30/200
= 0.15 or 15%
The correct option is, therefore, A.
describe or draw where each of the 6 junctions would be found on an epithelial cell
Answers
Epithelial cells are polarized, meaning they have distinct apical and basolateral domains. There are six types of junctions that can be found in epithelial cells:
1. Tight junctions (also known as occluding junctions): These junctions are located at the apical end of the lateral membrane between adjacent epithelial cells.
Tight junctions form a barrier that prevents the movement of molecules between the cells and are critical for maintaining tissue integrity.
2. Adherens junctions: These junctions are found just below the tight junctions, at the apical end of the lateral membrane.
Adherens junctions anchor the actin cytoskeleton of one cell to that of an adjacent cell, providing structural stability to the tissue.
3. Desmosomes (also known as macula adherens): These junctions are located along the lateral membrane between adjacent cells, below the adherens junctions.
Desmosomes provide strong adhesion between cells and are important for tissue strength.
4. Gap junctions (also known as nexus): These junctions are found throughout the lateral membrane of epithelial cells.
Gap junctions allow small molecules and ions to pass directly between cells, enabling communication and coordination between cells.
5. Hemidesmosomes: These junctions are located at the basal end of the lateral membrane, where the cell attaches to the underlying basement membrane.
Hemidesmosomes anchor the intermediate filaments of the cell to the basement membrane, providing structural stability to the tissue.
6. Focal adhesions: These junctions are located at the basal end of the cell, where the cell attaches to the extracellular matrix.
Focal adhesions anchor the actin cytoskeleton of the cell to the extracellular matrix, providing structural stability and allowing the cell to migrate and interact with its environment.

Answers
The importance of stem cells is that they are differentiated and can become daughter cells.
Why are stem cells important in differentiation?Stem cells have the potential to serve as the foundation of treatments for a wide range of illnesses due to their capacity to develop into almost any type of cell in the body. Standardized methods for stem cell cultivation and differentiation will be created as research advances.
In the body, stem cells have the capacity to differentiate into a wide variety of cell types. They act as the body's system for repairs. Adult stem cells and embryonic stem cells are the two primary categories of stem cells.
Therefore, one can say that daughter cells are created when stem cells divide properly in the body or a lab to create more cells. These daughter cells either differentiate into more stem cells or into cells with a more focused purpose.

The energy animals need to survive was once energy from the sun.
What evidence from the article supports this claim? Think about energy pyramids, then explain how the evidence from the article supports this claim.
Answers
Answer: The energy from the sun is the only source of energy which has the ability to sustain life on earth.
The energy pyramid states that the transfer of energy is unidirectional and it flows from the producers to the consumers.
There are different trophic levels at which the organism are found say herbivores, carnivores and top predators.
All of the organism are dependent on the producers for their source of energy.
hence, the sunlight helps autotrophs to make food and herbivores feed on them and then the carnivores animals feed on herbivores and then the top predators feed on the carnivores animals.
So, ultimate source of energy on earth is sun, which directly or indirectly provides energy to the producers and other animals.

Answers
Centrioles are the organelles involved in cell division
What is cell division?
The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle. Meiosis is a type of cell division that creates haploid gametes for sexual reproduction by reducing the number of chromosomes from two of each type in the diploid parent cell to one of each type in the daughter cells. Mitosis is a type of cell division that produces daughter cells that are genetically identical to the parent cell.Role of centrioles in cell division:
The fundamental units of centrosomes are centrioles, which are tiny cylinders (microtubules). Each centrosome is made up of two centrioles, which are each made up of nine microtubule triplets organized in the shape of a cylinder. Centrioles are hypothesized to be involved in the completion of cytokinesis during the process of cell division and are in charge of arranging the spindle fibers in the mitotic spindle apparatus.Hence the centrioles are the organelles involved in the prosses of cell division
