Answer: Oxaloacetate
Explanation: The krebs cycle starts with the pyruvic acid that is obtained after glycolysis. The Kreb's cycle begins when the Acetyl coA combines with a four molecule oxaloacetate.
The main product formed is citric acid thats why the cycle is also called as citric acid cycle. After the citric acid is formed it goes through a series of reactions to form NADH, FADH2 and ATP.
The carbon dioxide is also released during this process. The oxaloacetate formed is used to start the cycle so its is regenerated again and again.
Oxaloacetate is the molecule that is essential to regenerate at the end of the Kreb's cycle to start the process again.

all yellow
B.
all green
C.
three-fourths yellow and one-fourth green
D.
three-fourths green and one-fourth yellow
Answer:
The correct answer would be A. all yellow.
Let "Y" be the dominant allele and "y" be the recessive allele of the gene responsible for the color of the seeds.
Dominant allele "Y" codes for the yellow color of the seeds when present in homozygous as well as heterozygous condition whereas recessive allele "y" codes for the green color of the seeds only when present in homozygous condition.
Now, the genotype of a true-breeding plant with yellow seeds would be YY and that of a true-breeding plant with green seeds would be yy.
The gametes formed by yellow seed plant would be Y and gametes formed by green seed plant would be y.
The cross will result in the production of offspring each with genotype Yy.
Hence, all the offspring plants would produce yellow seeds as yellow is a dominant character.
The purpose of ethical guidelines for handling of experimental subjects is to ensure the safety and well-being of all living creatures in an experiment.
Ethical guidelines include issues such as human rights, animal welfare, safety compliance with the law, conflicts of interest, health standards..
Ethical guidelines are the norms for the acceptable and unacceptable behaviors of the researchers.
Answer: To ensure the safety and well-being of all living creatures in an experiment
Explanation:
During S phase, DNA replication occur during the cell cycle for each daughter cell to receive a complete copy of DNA.
A cell'sgrowth and division are accompanied by a sequence of processes known as a cellcycle.
A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.
Following this, the celldivides into two daughter cells, distributing one copy of the duplicated material to each. When each daughter cell has its own outer membrane around it, the cell cycle is finished.
Genetically speaking, the parentcell, together with the two brand-new daughter cells, are all the same.
Prior to mitosis and cell division, DNA replication takes place during the S phase (also known as the Synthesis phase) of the cell cycle.
Thus, the DNA replication occur during Sphase of the cell cycle.

Prominences are indeed a common phenomenon observed in the Sun's atmosphere, specifically in the solar chromosphere and corona.
A prominence is a relatively cooler and denser structure composed of solar gases, primarily hydrogen and helium, that becomes visible as a bright, arch-like or loop-like feature extending from the Sun's surface. Location: Prominences are located above the Sun's visible surface, known as the photosphere, in the outer layers of the solar atmosphere. They are best observed during solar eclipses or through specialized solar telescopes equipped with filters to block out the intense brightness of the Sun's photosphere. Types of Prominences: There are two main types of solar prominences: quiescent prominences and eruptive prominences.
prominences are prominent features seen in the Sun's outer atmosphere, characterized by arch-like structures formed by cooler and denser solar gases. They are manifestations of the Sun's complex magnetic activity and provide valuable insights into solar behavior, contributing to our understanding of solar physics and space weather phenomena.
