Answer: It is Atom and the charge would be postive.

Explanation: If the atom had 8 protons and 8 electrons (oxygen for example), knocking one of the electrons out, makes 8 protons and 7 electrons. The atom now has a net charge of +1 because the 7 electrons cancil the positive charges of 7 of the protons in the nucleus, but there is one remaining proton with a positive charge.Oxygen's 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron. Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!

Hope this helps :) Can u plz mark me branliest :)

A particle of oxygen has 8 protons and 8 electrons in an atom and the charge on it is zero.

It is the smallest particle of matter composed of electrons and a nucleus of protons and neutrons.

It is an atom with a positive or negative charge due to either loss or gain of electrons.

Every atom tends to have a noble gas configuration for stability and they either tend to lose, gain, or share electrons to achieve it.

The oxygen atom generally gains 2 electrons to complete its octet and has a net -2 charge.

Answer:

Because they are triploblastic ( Triblastica ).

Explanation:

Their body is composed of endoderm, mesoderm and ectoderm. While Cnidaria are Diblastica, so they are composed only from two layers: endoderm and ectoderm.

In addition larvae of Echinoderms are bilaterally symmetrical and they become nearly-radial only as adults.

Explanation:

The only true reactant of glycolysis is a molecule of glucose. Two molecules each of ATP and NAD+ (nicotinamide adenine dinucleotide, an electron carrier) are introduced during the series of reactions.

Answer:

The correct answer is - sea cucumber.

Explanation:

Hydra, aurelia, and sea anemone belong to Phylum - Coelenterata or cnidaria while sea cucumber is a member of echinoderms. Cnidaria is radially symmetrical, free-swimming or fixed, aquatic and solitary or colonial animals. While sea cucumber are animals like starfish or sea urchin.

They found on the seafloor and have pentaradial symmetry however, developes bilateral symmetry later.

Explanation:

Nucleic acids are made up of chains of many repeating units called nucleotides (see bottom left of Figure 1 below). The DNA molecule actually consists of two such chains that spiral around an imaginary axis to form a double helix (spiral.)  Nucleic acid molecules are incredibly complex, containing the code that guarantees the accurate ordering of the 20 amino acids in all proteins made by living cells.  Surprisingly though there are only a few different nucleotides: only four different nucleotide units comprise DNA, the nucleic acid of interest to the genealogist.  

This figure is a diagram of a short stretch of a DNA molecule which is unwound and flattened for clarity. The boxed area at the lower left encloses one nucleotide.  Each nucleotide is itself make of three subunits:

A five carbon sugar called deoxyribose (Labeled S)

A phosphate group (a phosphorous atom surrounded by four oxygen atoms.) (Labeled P)

And one of four nitrogen-containing molecules called nucleotides . (Labeled A, T, C, or G)

Alternating sugar and phosphate units form the two sides of a ladder-shaped arrangement with the rungs or steps each formed by a pair of nucleotide bases. Figure 2 below shows the structural formula of DNA in greater detail. The nitrogen bases are ring compounds with their carbon and nitrogen atoms arranged in single or double rings.  Only certain bases can pair together to form base pairs.  In DNA, Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).  

Notice that in the two figures above, the two strands of a DNA molecule are antiparallel, that is, they run in different directions. The side of the chain on the left begins with a free phosphate group at the top and ends with a sugar molecule at the bottom.  In contrast, the complementary chain on the right begins at the top with a sugar molecule and ends at the bottom with a phosphate group.  

Happily, it is not necessary to hold the details of DNA structure in your mind at all times!   As the sugar and phosphate sides of the molecule are constant they are frequently represented by parallel lines.  Even better, each of the nitrogen bases is conveniently represented by the first letter of its name.  These conventions allow the simplified representation of the molecule shown in the figure below

Or, even easier, a section of a DNA molecule is often abbreviated to show the bases of just one strand:

A T G G C T A C

Knowing the base pairing convention of A always pairing with T and G always pairing with C makes the complementary strand of the molecule understood.  It is this feature of complementary base pairing that insures an exact duplicate of each DNA molecule will be passed to its daughter cells when a cell divides.

A. Recombinant DNA

Recombinant DNA is created by a process called genetic recombination. In this process, we insert a exogenous gene to let another organism, a bacteria in this case, produce a protein that can not be produced otherwise

Answer:

Genus = Elephas

Species = maximus

Explanation:

Carolus Linnaeus, who is considered to be the FATHER OF TAXONOMY for his immense contribution to the classification of living organisms. Carolus Linnaeus between the year 1735 and 1758, developed a scientific system of naming organisms using two-way naming system called BINOMIAL NOMENCLATURE.

The two Latin names given to organisms were derived from their generic and specific epithet i.e. one of the names is GENUS and the other SPECIES. According to this question, the scientific name using the binomial naming system for Indian elephant is Elephas maximus. This means that Elephas is the part that refers to GENUS while maximus is the part that refers to SPECIES.

A nucleotide is a compound containing three component units namely a pentose sugar, a heterocyclic nitrogenous base and a phosphate group. The nitrogenous base present may be either purines or pyrimidine.

The sickle cell anemia is one of a group of inherited disorders known as the sickle cell disease. It affects the shape of the red blood cells which carry oxygen to all parts of the body. In sickle cell anemia some red blood cells are sickle shaped.

Red blood cells are usually round and flexible, so that they move easily through blood vessels. The sickle shaped red blood cells are also called crescent moons. These sickle cells also become rigid and sticky which slow or block the blood flow.

SCD causes a basal substitution of adenine A to thymine T in the sixth codon of beta globin. This leads to the replacement of glutamic acid with valine in polypeptide chains of haemoglobin.

Explanation:

Answer: D. Digestion increases as the volume of the enzyme increases.

Explanation:

Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster.

Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.
