Answer:
chewing gum
Explanation:
when chewing gum you'll likely think back to the last time you had gum. The trick is to study while chewing gum and, when you chew another piece of gum, you'll remember back to when you had it earlier along with the information that you remembered as you were chewing the gum.
Answer:
The correct answer is option a-"oceanic lowstand".
Explanation:
An oceanic lowstand is defined as a geological phenomenon at which the sea level is at a low point and the continents are mostly emergent. The Earth has been on onceanic lowstands historically. This has been identified by different evidence, including the Gulf Coast rivers formation of braided channels.
Answer:
Wingless offspring
Explanation:
Complementation is the terminology used for finding difference in the mutation of same or different gene.
Two groups with same complementation have failed to complement each other.
Thus, two wingless flies will have the same genotype i.e “ww”
When two wingless flies are crossed following offspring are produced
ww * ww
ww, ww, ww, ww
All the offspring are wingless too
Answer:
1. 80 chromosomes are found in each of the daughter cells. 2. Two daughter cells are produced. 3. The daughter cells are identical to each other.
Explanation:
Mitosis is simply a process of cell division whereby two daughter cells that are genetically identical are produced from a single parent cell. A cell having 80 chromosomes would undergo Mitosis through these various stages:
Interphase: This can be referred to as the rest phase between cell division when mature enough for reproduction. This is a preparatory stage where DNA is duplicated and ready for the division of chromosomes
Prophase: This stage marks the beginning mitosis of the cell with 80 chromosomes. The chromatin threads start a coiling process in which the chromosomes become condensed to enable easy distribution to daughter cells without tangling.
Prometaphase: This phase commences toward the end of the prophase, where the nuclear envelop breaks down. The chromosomes move toward to the center of the cell.
Metaphase: At this stage, the duplicated chromosomes line up on the mid plane or equator of the cell. During this stage, each chromatid is condensed completely and appears thick and distinct.
Anaphase: At this stage, the chromosomes move toward the poles as each replicated copies of the DNA of the cell ends up on either side of the cell. What we would have here at this stage is an entirely two new sister chromatid having 80 chromosomes. Cytokinesis begins towards the end of this stage as the parent cell cytoplasm divides which also continues at telophase.
Telophase: This is the final phase of Mitosis where two separate nuclei are formed and Cytokinesis takes place to complete the division of the cell to form two daughter cells having the same number of chromosomes. These cells are genetically identical to the original parent cell.
The second law of thermodynamics states that a spontaneous process increases the entropy of the universe, S(univ) > 0. If ΔS(univ) < 0, the process is nonspontaneous, and if ΔS(univ) = 0, the system is at equilibrium
<h3>What is thermodynamics ?</h3>
The science of thermodynamics examines the connections between heat, work, temperature, and energy. The rules of thermodynamics explain how energy moves inside a system and whether or not the system is capable of performing beneficial work on its surroundings.
- Energy cannot be generated or destroyed, according to Thermodynamics' First Law. The entropy of the cosmos increases for spontaneous processes, according to the second law of thermodynamics. Third Law of Thermodynamics: Entropy is zero in a flawless crystal at absolute zero Kelvin.
