9. What type of bond is pictured in the image below?
a. covalent bond
b. ionic bond
c. metallic bond
d. electron bond
ONLY 9
Answer:
c. metallic bond
Explanation:
Metallic bonding, unlike other forms of atomic bonding, involves delocalized elections. The negatively charged electrons form a "sea" around metal cations. Electrons within the valence shells of metals are only held loosely within their molecular orbits- the metals are held together due to the strong attraction between these delocalized electrons and positive nuclei.
The electrons are typically described as mobile, free, and delocalized. These traits are responsible for several metallic properties such as:

Briefly explain how each layer interacts with electromagnetic radiation from the sun by describing the temperature changes that occur
Explanation:
The layers of atmosphere are differentiated on the basis of different temperature gradients.Thus,different layers within the atmosphere are created.
Toposphere is heated from the ground. Thus, with increase in altitude temperature decreases.
In the stratosphere, temperature increases with altitude. The direct heat source for the stratosphere is the Sun. Air in the stratosphere is stable because warmer, less dense air sits over cooler, denser air.
In Mesosphere temperature decreases with altitude. Few gas molecules present in mesosphere absorb sun's radiation.The heat source is the stratosphere below. The mesosphere is extremely cold, especially at its top, about -90°C.
Thermosphere which also contains ionosphere.The density of molecules is so low in here that one gas molecule could easily go upto 1 km before it collides with another molecule. It is so little energy is transferred, the air feels very cold

When a bee visits a flower for sweet, sweet nectar, the plant's gametes are also spread to anoher plant. What kind of symbiotic relationship is this?
Answer:
Mutualism
Explanation:
Mutualism is a type of symbiotic relationship in which the two species of organisms involved benefit from one another i.e. the actions of one benefits the other.
In this question, a bee is said to visit a flower for sweet nectar, however, in the process of feeding on the flowers nectar, the plant's gametes are also spread to another plant by the bee. This is a type of MUTUALISTIC RELATIONSHIP because the plant is beneficial to the bee by providing food (nectar) while the bee also helps the plant by helping it pollinate.
Why can a planet orbit circular?
Answer:
Explanation:A circle is merely a special case of an ellipse. However, the planets do not quite move in ellipses either. The increased kinetic energy of a planet as its distance from the Sun decreases causes it to behave as though it had a greater mass, which results in the point of the orbit furthest from the Sun precessing.

Which student will most likely overcome their nerves?
A.one who thinks positively and practices the speech in advance
B.one who thinks positively and stays up late to practice the speech
C.one who gets plenty of rest and eats sugary foods for energy
D.one who gets plenty of rest and avoids practicing the speech
Answer:
A.one who thinks positively and practices the speech in advance
Explanation:
It makes more sense
Student will overcome their nerves who thinks positively and practices the speech in advance
Positive behaviourThe person who thinks positively and practices the speech in advance will most likely overcome their nerves because the positive behaviour has good effect on the personality of an individual. Those people who think negative, they will not get success in their life.
Practice's benefitsThere is a saying that practice makes a man perfect. That person who regularly practice a specific topic, they can do the speech very well or other things in their life so we can conclude that student will overcome their nerves who thinks positively and practices the speech in advance.

Question 4 of 10
Which is the smallest division of geologic time?
O A. Eon
O B. Period
O C. Era
O D. Epoch
Answer: Epoch
Explanation: An epoch is the smallest unit of time on the scale, but still encompasses a period of millions of years. Chronologically, epochs are grouped together into larger units called periods. Periods are combined to make a subdivision called an era. An eon is the largest division of geological time.
The smallest division of geologic time is an epoch. Thus, the correct option is D.
What is an Epoch?The geologic time scale is a representation of the time based on the rock record of the Earth. It is a system of chronological dating which uses the process of relating strata to time and the scientific branch of geology that aims to determine the age of rocks.
An epoch or reference epoch is an instant in time which is chosen as the origin of a particular calendar era. The epoch serves as a reference point from which the time is measured.
An epoch is a division of the geologic period and it is the smallest division of geologic time which lasts for over several million years.
Therefore, the correct option is D.

In essence, DNA is a thin and very, very long organic molecule. It is a polymer, and each of the monomers that constitute it are called ______
Answer:
Nucleotides
Explanation:
DNA is a polymer of nucleotide monomers.
Nucleotides are made of a nitrogenous base (either adenine, thymine, guanine, or cytosine), a deoxyribose sugar, and a phosphate group.
The nucleotides are joined together by phosphodiester bonds between the sugar of one nucleotide and the phosphate group of the next.
Which biomolecule provides the instructions to build enzymes?
A. Carbohydrates
B. Lipids
C. Nucleic acids
D. Proteins
Proteins are the building blocks of enzymes, and proteins are made up of amino acids that are linked together in one or more polypeptide chains. Therefore, option (D) is correct.
What are enzymes?Enzymes are proteins that aid in the acceleration of metabolic processes, also known as the chemical reactions that take place in our bodies. They are responsible for the creation of some chemicals while also decomposing others. Enzymes are present in everything that is alive. Enzymes are something that are produced by our bodies spontaneously.
Enzymes regulate most biochemical reactions in animals, plants, and microbes, thus there are many examples. Animal digestive enzymes are well-known. Gastric juices break down food with the enzyme pepsin. Salivary amylase turns starch into sugar, starting digestion.

In gel electrophoresis, fragments are separated by size and electrical charge by applying __________ to them
Answer:
Gel matrix
Explanation:
Gel electrophoresis is a technique in molecular biology used to separate fragments of biomolecules such as DNA, RNA, protein by applying electric current through a GEL medium. The basis of separation of this fragments is their sizes and electrical charge.
In the gel electrophoresis procedure, a GEL medium made of Agarose is used. The DNA fragments, which are then negatively charged begins to move towards the positive end of the gel when electric current is supplied. The smaller fragments move/migrate faster than the larger ones towards the positive end. Therefore, In gel electrophoresis, fragments are separated by size and electrical charge by applying GEL to them.
Stars form from what celestial objects ?
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example, a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. Stars begin their lives as clouds of dust and gas called nebulae. The gravity of a passing star or the shock wave from a nearby supernova may cause the nebula to contract. Matter in the gas cloud will begin to coalesce into a dense region called a protostar.
