(JSYK: this is technically biology)

Anyways, a gymnosperm is a plant (usually a tree) that has unprotected seeds, this means it bears no fruits and can include (but are not limited to) connifers, cycads, and the ginko. Angiosperms produce flowers to help fertilization and have protected seeds. They are also likely to produce fruits or vegetables.

DNA and RNA have base pairs that form hydrogen bonds with complementary bases. The DNA molecule shown contains adenine, cytosine, guanine, and thymine. Which base does RNA not have?
A) Thymine B) Adenine C) Guanine D) Cytosine

Answers

Answer:

Thymine

Explanation: I took the test

The DNA molecule shown contains adenine, cytosine, guanine, and thymine. The base that RNA does not have is Thymine. The correct option is A.

What are DNA and RNA?

DNA and RNA both are genetic materials, and they both represent the genetic material of living organisms. All animals contain DNA in their body. Some plants or bacteria contain RNA as genetic material.

DNA and RNA both contain bases that are attached with a hydrogen bond. These bases are adenine, cytosine, guanine, and thymine. In RNA, the same bases are present.

In RNA, in place of thymine, there is uracil present. Uracil and adenine are joined together with a hydrogen bond. Cytosine and guanine are present together with a hydrogen bond.

Thus, the correct option is A.Thymine, regarding the base present RNA.

state two advantages of parallel over series connection in table form?

Answers

Advantages of parallel combination over series combination are:

1) In parallel combination each appliance gets the full voltage.

2) If one appliance is switched on/of others are not affected.

3) The parallel circuit divide the current through the appliances. Each appliance gets proper current depending on its resistance.

4) In a parallel combination it is very easy to connect or disconnect a new appliance without affecting the working of other appliances.

choose what you like!

Note that there are also some disadvantages to using parallel connections over series connections, such as increased complexity in wiring and the need for additional safety measures when working with high voltage circuits. The choice between series and parallel connections depends on the specific requirements of the circuit and the devices being used.

Calculate the density of an object using the following information: Mass = 50 grams and the initial water level is 30-ml in a graduated
cylinder, but rose to 40-ml after the object was dropped into it.

Answers

The density of an object = 5 g/ml

Further explanation

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

The unit of density can be expressed in g/cm³ or kg/m³

Density formula:

[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]

ρ = density

m = mass

v = volume

Mass = 50 g

Volume of the object =

[tex]\tt 40-30=10~ml[/tex]

So the density :

[tex]\tt \rho=\dfrac{50}{10}\\\\\rho=\boxed{\bold{5~g/ml}}[/tex]

How does the atomic mass of the atom change when an electron is added or removed?

Answers

If you could magically make two neutrons in the nucleus of an atom disappear, the atomic number and the electrical charge of that atom would remain unchanged. Neutrons do not carry an electrical charge so adding or removing them from the nucleus does not change the electrical charge of the nucleus. It does, however, change the mass of the nucleus. Adding or removing neutrons from the nucleus are how isotopes are created.

Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium. (Actually, a few neutrons have to be added as well to make the new nucleus stable, but the end result is still helium.) Keep in mind that atoms, by definition, are electrically neutral and always contain the same number of protons and electrons.

What is a Chemical reaction?When atoms establish or break chemical bonds, chemical processes take place. Reactants are substances that begin a chemical reaction, while products are the compounds that are created as a result of the reaction. Until the reactants are exhausted, some chemical reactions merely proceed in one direction. It is claimed that these responses are irreversible. Some responses are categorized as reversible. Reactions that are reversible can occur both forward and backward. Reactants change into products in a reversible reaction, but products can also change back into reactants. In actuality, both the forward response and its reverse will occur simultaneously. This oscillation lasts until a particular relative balance between reactants and products is attained a condition known as equilibrium. The forward and backward processes continue to occur at equilibrium, but there is no longer any change in the relative concentrations of products and reactants.
