Answer:
Option B, Xylem --> phloem --> endodermis --> stele --> epidermis --> cortex --> cambium ///
Explanation:
The start of water transportation via roots takes place through the Xylem as these are the specialized cell in roots to intake water from the ground. These cells are arranged in the form of layer and filters the water before transporting. After the filtration in Xylem, water then passes to phloem (which are also part of conducting system of plants and runs parallel to the xylem). After the phloem, water then goes to the central part of the root which is known as stele and then it reaches the epidermis. From epidermis , absorbed water then goes to the cortex of other tissues and organ and finally it reaches the cambium.
Hence, option B is correct
the length of its year
B.
the length of its day
C.
the length of its month
D.
the length of its decade

Answer:
The correct answer is B-cells
Explanation:
There are two types of lymphocytes B- lymphocytes and T- lymphocytes. B lymphocytes or B cells when interacts with the antigen with its B cell receptor it differentiates into two cell memory B cells and plasma B cells.
Plasma B cell is responsible for secreting various antibodies and these antibodies bind to the epitope region of antigen and helps in opsonization and killing of antigen. Memory B cell helps in generating quick immune response when that antigen comes again in the body. Therefore the correct answer is B cells.
The chromosomal mutation is C. Nondisjunction .Therefore , C. Nondisjunction is correct .
There are a number of factors that can increase the risk of nondisjunction, including:
Age: The risk of nondisjunction increases with age, especially in women.
Genetic factors: People with certain genetic conditions are at increased risk of nondisjunction.
Environmental factors: Exposure to certain environmental toxins, such as radiation, can also increase the risk of nondisjunction.
There is no cure for nondisjunction, but there are a number of things that can be done to manage the symptoms and improve the quality of life of people with nondisjunction-related birth defects.
Here are some additional details about nondisjunction:
Nondisjunction can affect any chromosome, but it is most common on chromosomes 21, 13, and 18.
Nondisjunction is estimated to be the cause of 50-60% of all miscarriages.
Nondisjunction is also the cause of some stillbirths and birth defects.

Identification of mutation type, such as point mutation, silent mutation, insertion, deletion, transversion, or transition, depends on the specific changes in DNA or RNA sequences. For example, a change in a single base pair signifies a point mutation.
A thorough identification of the type of mutation seen on Chromosome 20 goes beyond merely looking at the question diagram. It depends on the specific alteration of the DNA or RNA sequences. Several types of mutations exist including point mutations, silent mutations, insertions, deletions, transversions and transitions, among others.
As an illustration, suppose the mutation involved a single base pair alteration, this would be a point mutation where one nucleotide is substituted with another. Transversions involve switching a purine with a pyrimidine or vice versa. If the mutation led to an addition or removal of a base pair, this would be termed an insertion or deletion respectively. Occasionally, a fraction of DNA from one chromosome may get transported to another chromosome or a different part of the same chromosome, a scenario known as translocation.

Answer: Exergonic reaction; Endergonic reaction
In coupled reactions, the energy released by an exergonic reaction is used to drive an endergonic reaction. ATP breakdown is often coupled to cellular reactions that require an input of energy.
Explanation:
Cellular reactions include Exergonic and endergonic reactions. An exergonic reaction is one that occurs spontaneously and brings about the release of energy (in form of ATP). On the other hand, an endergonic reaction proceeds only with the input of energy.
Thus, exergonic reactions are usually coupled to endergonic reactions
In coupled reactions, the energy from an energy-releasing exergonic reaction, like the breakdown of ATP, is used to drive an energy-requiring endergonic reaction. These reactions usually occur together in a cell.
In coupled reactions, the energy released by a exergonic reaction is used to drive an endergonic reaction. An exergonic reaction is a chemical reaction where energy is released, often in the form of ATP (Adenosine Triphosphate). On the other hand, an endergonic reaction requires energy to proceed.
In a cell, these types of reactions often happen together (or are coupled) so that the energy released by an exergonic reaction, like the breakdown of ATP, gets immediately used to power an endergonic one, such as the synthesis of cellular components or the transport of molecules across the cell membrane.
