all plant bodies(root,stem and leaf) are externally covered by epidermis but why woody plant is covered by barks
Answer:
Bark comprises all the tissues surrounding the xylem in woody plants. Broadly, bark includes an inner and mostly living region and an outer, dead one. Of all plant structures, bark has the most complex anatomical structure and ontogenetic origin involving two (and often three) different meristems.
As to why, the bark adds layers to the inside ring of the vascular cambium, the outside is pushed outward. The cells die off, and the fibrous matrix of cellulose and lignin molecules remain. This hard structure forms the bark, and protects the tree or plant from many forms of damage.

Answer:
The time required to double the population is going down.
Explanation:
2022 Accelerate (option D)
According to the human population today, the time required to double the population is going down.
What do you mean by human population?"Population is the whole number of inhabitants occupying an area and continually being modified by increases (births and immigrations) and losses (deaths and emigrations)." As of now, the rate of birth and immigration is higher than that of death and emigration, due to which population is increasing rapidly.The current human population estimated to have exceeded 7.9 billion.Hence, the correct option is C. The time required to double the population is going down.

what is the meaning of
•molecule
•compound
•atom
•element
•organic compound
•inorganic compound
Molecule: a molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of two or more atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among said atoms. Although oxygen is an element, it naturally has 2 atoms (O2), because it is a halogen and in order to reach 8 valence electrons and become stable and unreactive, it bonds with another oxygen atom. This means that oxygen atoms and oxygen molecules are different; one is an element, the other is a molecule.
Pure Substance: can be divided into two sub-categories: compounds and elements.
Compound: A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound, meaning that oxygen molecules (O2) are NOT compounds. NaCl, or table salt, is.
Atom: An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms.
Element: An element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nuclei. Elements are the base, more "pure" of the pure substances. Each element is assigned a symbol. Perhaps the most recognizable of them is H, for hydrogen.
Organic Compounds: organic compounds are generally any chemical compounds that contain carbon-hydrogen bonds. The study of these is called organic chemistry. I mean, carbon is the basis of ALL known life.
Inorganic Compounds: They are any substance in which two or more chemical elements (usually other than carbon) are combined, nearly always in definite proportions. Compounds of carbon are classified as organic when carbon is bound to hydrogen. THE OPPOSITE OF ORGANIC COMPOUNDS.

what is the botanical name of milk
Answer:
Milk of magnesium's scientific name is magnesium hydroxide, and the scientific name for milk of sulfur is precipitated sulfur.
The botanical name of milk is not applicable, as it is not a plant or a plant product. Botanical name is the scientific name given to plants, fungus and algae.
Milk is a nutrient-rich fluid produced by mammals. It is frequently consumed as a source of nutrients and is renowned for having a lot of calcium. Water, lipids, proteins, carbs, vitamins, and minerals are all present in milk in complicated proportions.
There is no particular botanical name for milk in the field of biology, which is the study of plants and their categorization. Different plant species are identified and categorized using botanical names.
Milk lacks a botanical name since it is a byproduct of animals, not plants.

Why is the genetic code common to all organisms!
Answer:
Why Is DNA Considered a Universal Genetic Code? DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... All organisms also use DNA to transcribe RNA, and then they translate that RNA into proteins. Every living organism uses that same system.
Explanation:
The genetic code is universal because it is the same among all organisms. Replication is the process of copying a molecule of DNA. Transcription is the process of converting a specific sequence of DNA into RNA.
Protein-encoding genes specify the sequences of amino acids, which are the building blocks of proteins. In turn, proteins are responsible for orchestrating nearly every function of the cell. Both protein-encoding genes and the proteins that are their gene products are absolutely essential to life as we know it.

The cell cycle is the life of the cell from the time it is first formed from a dividing parent cell until its own division into two cells
Explanation:
cell cycle is made up of three main parts: interphase, mitosis, and cytokinesis. Most biologists agree that interphase makes up the period of time that a cell would be preparing for cell division. Cells spend the majority of their lives in this stage. During interphase a cell is going to be growing, replicating its genetic material and essentials to carry out cell division, and proofreading the genetic material to ensure replication has occurred correctly. This doesn’t sound like much, but it’s actually the longest part of the cell cycle. Once this is complete, the cell will then go through cell division and, theoretically, split into two new cells (cytokinesis).
How cytokinesis works will depend upon the type of cell that is dividing. Here is an image that summarizes the differences in cytokinesis in plant cells and animal cells, which is the classic example used in many introductory biology courses:
in pcr,
a. the gene sequence is determined
b. multiple copies of the dna sample are made
c. dna is destroyed so it has no value
Answer:
b. multiple copies of the dna sample are made
Explanation:
Polymerase chain reaction (PCR) is a method used to make millions to billions of copies i.e. complete copies or partial copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it. The new fragments of DNA that are synthesize during Polymerase chain reaction (PCR) also serve as templates to which the DNA polymerase enzyme can attach and start making DNA. The result of this attachment in a production of huge number of copies of the specific DNA segment in a short period of time.
Organisms of either extreme characteristic dying out while organisms with the medium characteristic have a higher fitness is identified as?
Answer: Stabilization selection
Explanation:
Natural selection involves the differential survival and growth of organisms which have suitable traits to survive in unfavorable or adverse environment. Such traits are passed on to the next generation. Stabilization selection is a type of natural selection in which the nature selects the non-extreme phenotypic traits. Middle traits are selected and such organisms grow and reproduce. Example can be given that of human babies in which babies with low weight lose more heat and babies with high weight are difficult to be delivered from the pelvis. Therefore, babies with middle weight are expected to survive more than that of low or middle weight.

Using the allele symbols in the table, identify the genotype of a guinea pig that is recessive for hair length, heterozygous for hair color, and homzygous dominant for hair texture.
Answer:
Hair length: hh
Hair color: Bb
Hair Texture: RR
Explanation:
In order for the recessive gene to show for hair length, two of the same alleles must be present, so, in this case, hh.
The question states "heterozygous for hair color." This tells you that the genotype will be Bb. Heterozygous means two of the different alleles. This is different from homzygous.
The question states "homzygous dominant for hair texture." This tells you that it will contain two of the same alleles. The question also tells you that it is homzygous dominant, which means there will be two of the same dominant alleles, so, RR.
