Answer: Every cell in a plant contains all the genetic information to create specialized and unspecialized tissues. It uses gene expression and regulation to control what those cells become after mitosis making it easy to create different types of cells from one cell.
Explanation:
i need an explanation for this myth i have made for my science assignment "why are fish and plants not in the same phylum"
Answer:
They can't be in the same phylum because they are in two different categories on the basis of Mode of nutrition. Plants are autotrophs, while animals are heterotrophs. Cell wall is present in plant cells, while it is absent in animal cells.
Explanation:
A phylum is a major group of animals or in some classifications plants sharing one or more fundamental characteristics that set them apart from all other animals and plants/

Answer:
A
Explanation:
Even though individuals only have two alleles for any given gene, there may be many different alleles for that gene within the human population. What is the term for this phenomenon?
Group of answer choices
Multiple alleles
Genetic diversity
De novo mutation
Allelic variety
Answer:
Genetic diversity
Explanation:
Genetic diversity is when a population of a species, humans, in this case, have different genes between different individuals. One person may have blue eyes while the others have brown. This shows diversity within the gene pool.
Genetic diversity is also important to the survival of a species. Two-parent reproduction leads to genetic diversity. Having different alleles within a population allows for adaptation. On the other hand, one-parent reproduction does not allow for genetic diversity. This hinders the species because it does not let species to slowly improve the gene pool through natural selection and adaptation.
The 16s rRNA gene encodes an RNA that would be used as a component of the _________ during ____________.
a. RNA polymerase, transription
b. a protein, DNA replication
c. the ribosome, translation
d. tRNA, DNA replication
The 16s rRNA gene encodes an RNA that would be used as a component of the ribosome during translation (Option c). It is a ribosomal RNA.
What are ribosomal RNAs?Ribosomal RNAs (rRNAs) represent fundamental components of the ribosomes, the protein factories of the cell.
Ribosomes play central roles during the process of translation by which an mRNA is used as a template to produce a polypeptide.
The 16S rRNA is a constituent of the bacterial small ribosomal subunit, which is used during translation.

Explanation:
Livestock :- animals that are kept for the goods they offer and that can be sold for profit
Overharvesting :- catching or removing from a population more organisms than the population can replace
Aquaculture :- involves raising aquatic organisms for human use
Drought :- lack of water in an area causing crops to die
Famine :- the social and economic crisis in a given area that is commonly characterized by widespread malnutrition, starvation, etc.
Malnutrition :- when an organism does not consume enough nutrients needed to fulfill the body's needs
Diet :- The type and amount of food a person eats
Pesticides :- Chemicals that protect crops from harmful plants and insects
Carbohydrates :- Primary source of energy for the body
Erosion :- the wearing away of soil by wind and water
Compare and contrast each of the following pairs of terms: (a) circulatory system and cardiovascular system, (b) complete blood count and complete blood count with differential.
The circulatory and cardiovascular system are responsible for bringing nutrients and oxygen to all the cells, therefore, a complete blood count quantifies and evaluates different types of blood cells, while a complete blood count with differential consists in recognizing and assessing the proportions of the different varieties of leukocytes.
What is circulatory system and cardiovascular system?The cardiovascular system covers those structures (heart and blood vessels) that allow blood and lymphatic circulation (circulatory system).
What is a complete blood count?It is a scheme that allows to represent the composition of the blood.
What is a complete blood count with differential?It is one of the tests that allows counting each of the leukocyte types.
Differences between circulatory system and cardiovascular system, complete blood count and complete blood count with differentialCirculatory system and cardiovascular system are linked to the set of organs and structures that allow blood and lymph to travel through the body.A complete blood count examines the types and numbers of cells in the blood: white blood cells, red blood cells and platelets by performing a blood count of these main cells.A complete blood count with differential is used to diagnose and monitor many different conditions, including anemia measuring the percentages of each type of white blood cell.Therefore, we can conclude that the circulatory and cardiovascular system are responsible for bringing nutrients and oxygen to all the cells, therefore, a complete blood count quantifies and evaluates different types of blood cells, while a complete blood count with differential consists in recognizing and assessing the proportions of the different varieties of leukocytes.
