When living yeast cells were placed in congo red dye and examined under the microscope, the yeast cells remained colorless. However, when placed in methylene blue, they became blue. Later, dead yeast cells were placed in congo red dye. These cells turned red. Explain these three observations.
Living cells remain colorless because of the presence of an enzyme. They cannot reduce the stain. Whereas, dead cells can reduce the stain and appear red while stained with congo red dye.
What is Staining?Staining is a technique used to enhance the contrast in samples to visualize the samples clearly. This makes the identification and observation of samples easy.
Living cells have an active dehydrogenase system which reduces methylene blue stain and dead cells are unable to reduce this stain. Thus living cells are colorless under this stain while the dead cells stain blue.
The Congo red stain is used for staining amyloids in cell wall of plants, fungi, and outer membrane of gram negative bacteria. Congo red is a synthetic dye, used for the differential staining of elastic fibers present in the cells of bacteria and plants.
Yeast are observed to be oval (egg shaped) organism under high resolution microscopes. It is also possible to observe the buds present on some of the yeast cells.
Methylene blue stain is used in determination of cell mortality. If methylene blue stain is applied to a sample, a healthy cell with turn the stain colorless. This is due to the enzymes, which reduce the methylene blue, causing it to lose its color.

The part of the brain where planning, language and advanced thought occur is:the hippocampus.the amygdala.the cortex.the hypothalamus.
The cortex, particularly the frontal lobe, is responsible for planning, language, and advanced thought processes. Higher cognition, impulse control, and language production are key functions of the frontal lobe, including areas like the prefrontal cortex and Broca's area.
The part of the brain where planning, language, and advanced thought occur is the cortex, specifically within the frontal lobe of the cerebral cortex. The frontal lobe is critical for cognitive functions and control of voluntary movement or activity. It is the part of the brain that is responsible for higher mental functions, such as thinking, planning, and memory, as well as judgment and impulse control.
The other options provided, such as the hippocampus, amygdala, and hypothalamus, play roles in emotion, learning, and hormone regulation, but not primarily in the higher-level cognitive processes associated with planning and language production. The prefrontal cortex, a part of the frontal lobe, is specifically associated with advanced thought processes, including problem-solving, decision-making, and social behavior. Furthermore, Broca's area, located in the frontal lobe, is essential for language production.

A proteins is a sequence of amino acids, which is coded for by sequences of dna. what specific part of a dna sequence codes for the amino acid sequence?
A protein is a sequence of amino acids which are coded by the sequence of DNA present in the nucleus of cell. The codes are in the form of codons which is made up of three nucleotide bases each.
What are codons?
Proteins are the building blocks of body. The process of formation of proteins takes place in the ribosome of cell and this process is known as translation. They are formed by the polymerization of amino acids into the form of long chains of polypeptides which undergoes post-translational modifications to form a functional protein.
Codons are the sequence of three nucleotide bases or triplets which codes for specific amino acids as well as stop codons. These codons are the sequence of nucleotides present in the DNA of the cell.

Select all of the answers that apply. Four laws or principles are involved with the study of stratigraphy. They are _____. 1 law of original horizontality 2 law of superposition law of original lateral continuity 3 law of gravity and oppositional force 4 law of cross-cutting relationships
Answer:
Option (1), (2) and (4) are the correct
Explanation:
According to the Steno, the four laws that deals with the study of stratigraphy are as follows-
Law of Superposition- this law states that in a geochronological sequence the rock layers that are present at the top are the youngest and the rock layers that lies at the bottom are the oldestLaw of Original horizontally- this law states that the sediments usually gets deposited in a horizontal manner due to the influence of gravityLaw of Cross-cutting relationship- this law states that in a particular area when the igneous bodies (such as batholith, plutons etc) intrudes other rocks, then these intruding features are generally younger than the rocks which it cuts, maintaining a cross-cutting relationshipLaw of lateral continuity- this law states that the the sediments at first are deposited and extended laterally in every direction until they meet another geological feature that interrupts its path of lateral extensionWhat is more stable a food chain or food web?

Which experiment is most likely to have reliable results? A. An experiment that proves the hypothesis B. An experiment in which there are no controls C. An experiment that confirms predictions D. An experiment in which the outcome is repeatable
Answer: D. An experiment in which the outcome is repeatable
Explanation:
An experiment is performed by utilizing a suitable methodology. The correctness of the methodology is analyzed by repeating a process several times so as to obtain concordant readings. Similarities in such readings with subsequent attempts will make the methodology as well as the outcomes of the results valid.
On the basis of the above explanation, D. An experiment in which the outcome is repeatable. is the correct option.
