Answer:
Transpiration
Explanation:
The process of converting the genetic message from DNA into RNA is called transcription.
Transcription is the phase of gene expression in which a certain part of DNA is copied into RNA. Transcription is carried out by the enzyme RNA polymerase which joins nucleotides to produce an RNA strand and uses a DNA strand as a template. The three stages involved in transcription are initiation, elongation, and termination.
Answer:
A is a eukaryotic cell while B is a prokaryotic cell
Explanation:
The researcher can conclude that cell A is eukaryotic while cell B is prokaryotic.
In eukaryotic cells, the DNA is located majorly in the nucleus and the replication of the DNA happens in the nucleus. Hence, it is only logical to find segments of new DNA in the nucleus of cell A during replication.
Prokaryotic cells, however, lack a nucleus. Their DNAs lie freely within the cytoplasm. This thus means that replication can only happen in the cytoplasm. Hence, it follows logically to find a new DNA segment in the cytoplasm of cell B.
I.
The second step of meiosis I is called
I.
Answer:
Prophase I
Metaphase I
Explanation:
One of the methods of cell division that results in four daughter cells is called meiosis. These cells have half of the number of chromosomes when compared to the parent cell. The sub-phases are prophase, metaphase, anaphase, and telophase. So the first and longest step is called prophase and the second step is called metaphase.
Answer:Prophase!Metaphase I!

The macromolecule that a dietician should monitor closely in a patient is : Carbohydrate
Macromolecules are molecules which are consisted of a large number of atoms. The macromolecule that the dietician should monitor closely is carbohydrates because carbohydrate consists of monosaccharides which includes sugar(glucose).
Hence we can conclude that The macromolecule that a dietician should monitor closely in a patient is : Carbohydrate

Answer: The statement which summarizes the law of segregation is as follows :
During the process of gamete formation, two different forms of a gene ( also called allele) segregate from one another in a random manner and each gamete thus formed, receives one copy of gene.
This is called the law of segregation. It was proposed by Gregor Mendel.
For example- The gene for plant height in pea exists in two forms which are T ( dominant allele- represents tall height ) and t ( recessive allele- represents dwarf height ). If a plant is heterozygous ( having different alleles Tt), it will give two different gametes ( T and t ) during gametogenesis.
These alleles are segregated in accordance with the law of segregation.
The Law of Segregation states that paired genes separate evenly into gametes during meiosis, giving offspring equal chances of inheriting either gene. This observation, derived from experiments with pea plants, is the basis for predicting offspring traits using a Punnett square. The mechanism enforcing this law is the first division of meiosis, though this was not understood during Mendel's lifetime.
The Law of Segregation, proposed by Gregor Mendel, states that paired genes (unit factors) separate or segregate equally into gametes (eggs or sperm) during meiosis. This means that offspring have equal chances of inheriting either gene from their parents. Observations from experiments with true-breeding pea plants led to this law. For instance, the F1 generation expressed the dominant trait while the F2 generation exhibited both dominant and recessive traits in a 3:1 ratio. This segregation of alleles is what allows for accurate predictions of offspring traits using a Punnett square.
Gametes receive one allele from each parent, resulting in three possible combinations for the F2 generation from a monohybrid cross: homozygous dominant, heterozygous, and homozygous recessive. Heterozygotes can result from two pathways, receiving one dominant and one recessive allele from either parent, which alongside homozygous dominant individuals, are phenotypically identical, hence supporting Mendel's observed 3:1 phenotypic ratio.
The physical basis of the law of segregation is the first division of meiosis where homologous chromosomes bearing different versions of each gene segregate into daughter nuclei. This underlining mechanism, however, was not understood by the scientific community during Mendel's lifetime.
