How do you find the number of electrons for any atom?
Answer:
To find the number of electrons an atom has, start by looking up the element you're working with on the periodic table and locating its atomic number, which will be in the upper left-hand corner of the square. Then, identify the charge of the ion, which will be written as a superscript to the right of the element.
Hope this helps!
Answer:
the atomic number of an element is simpliy
the amount of electron present in an atom

A trait I which the alleles are not dominant over one another
Answer:
They are co-dominance and incomplete dominance.
Explanation:
Co-dominance occurs when both alleles in a heterozygous genotype for a trait are both equally expressed. An example is the human AB blood group, in which both the A and B alleles are equally expressed.
Incomplete dominance occurs when the heterozygous genotype for a trait is expressed as a blend. An example is blue feather color in chickens, in which a black allele and white allele together are expressed as blue feather color.
Does the King Fish have the same organ of respiration as Dolphins do? Justify your answer
Answer:
Dolphins are mammals, not fish. Unlike fish, who breathe through gills, dolphins breathe air using lungs.
They don't have gills, so they can't breathe underwater like fish. They breathe through a set of nostrils on top of their heads known as a blowhole. While swimming or resting under the water, they can take breathes by exposing only the tops of their heads to the air.
Like all mammals, dolphins have lungs and breathe air. They are the organ of the respiratory system which process the air inhaled through the spiracle.

Germination can not be observed here, but if it is a monogenic trait controlled by complete dominance, then the genotype can be homo-zygous (e.g., AA) or heterozygous (e.g., Aa).
What is a dominant trait?In genetics, dominance refers to the phenomenon where one allele completely masks the expression of another allele (the recessive allele) in heterozygous individuals.
In this case, the genetic cross might be Parental 1 (AA) x Parental 2 (Aa) >> Filial 1 F1 1/2 AA + 1/2 Aa.
In conclusion, germination can not be observed here, but if it is a monogenic trait controlled by complete dominance, then the genotype can be homo-zygous (e.g., AA) or heterozygous (e.g., Aa).

Algae are the primary producer in the trophic levels. Therefore, option "C" is correct.
What are tropic levels?Tropic levels are the levels or steps in the food chain. In tropic levels, the energy is transferred to different levels through food produced by the lower levels. The source of nutrition varies in different food chains.
There are four types of tropic levels, first primary producers are the autotrophs which produce their own food. Second, are herbivores which consume the autotrophs also called primary consumers. Third are secondary consumers who are carnivores and fourth are the tertiary consumers who are also carnivores.
example: sun, plants, deer, and tigers.
Tropic levels play a key role in understanding the flow of energy.

What are the components of DNA? What’s the structure of nucleotides and how do they connect?
Answer:
Components of DNA includes ribose sugar, phosphate group and four nucleotides(Adenine,cytosine,thymine,guanine).
Explanation:
DNA is made up of two linked strands that are wrapped around each other in a coiled pattern forming the double helix.Each strand of the DNA is made of a backbone that consist of a ribose sugar and a phosphate group.Each phosphate group is attached to one of the four nucleotides(Adenine,cytosine,thymine,guanine).The two strands of a single DNA molecule are linked by the nucleotides.Adenine and Guanine are called purines.cytosine and Thymine are called pyrimidines.Adenine from one strand makes a double bond with Thymine from another strand linking the two strands of DNA molecule.Cytosine from one strand makes a triple bond with Guanine from another strand linking the two strands of DNA molecule.A picture of DNA and nucleotide structure is attached below.I hope it helps.why is it an advantage to move food around your mouth before you swallow it?

what is meiosis?Meiosis, also called reduction division, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or germ cells.
The process of meiosis is characteristic of organisms that reproduce through fusion. Such species have in the nucleus of each cell a diploid (double) set of chromosomes, consisting of two haploid sets (one inherited from each parent). These haploid sets are homologous—i.e., they contain the same kinds of genes, but not necessarily in the same form.
