Answer:

a. The letters Na with one dot

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.

Sodium is a chemical element that is found in group (1) of the periodic table and as such it has 1 electrons in its outermost shell. Also, the chemical symbol for Sodium is Na and it has one (1) valence electron.

A Lewis structure can be defined as a structural representation of an atom or molecule by using a dot to show the position and distribution of electron(s) around the atom or molecule.

Hence, the letters Na with one (1) dot is a correct Lewis structure diagram for Sodium (Na) because it has just one (1) valence electron in outermost shell.

For example, the Lewis structure diagram for Sodium (Na) is •Na.

Answer:

Na with 1 dot

Answer:

heterozygous; dominant; recessive; h.o.mo-zygous

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.

This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.

Trait can be defined as a distinguishing quality or characteristic of a living thing.

Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.

Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

In Genetics, when an individual has two (2) different versions of a gene, he or she is said to be genetically heterozygous.

In traits with a simple pattern of inheritance, only the trait conferred by the dominant form of the gene from the parent organism will be visible in the offspring of a living organism. The other form of the gene is recessive : it confers a trait that is only visible when the individual is genetically , or has two identical copies of the gene.

Answer:

Methionine- Lysine- leucine- stop

Explanation:

This question is describing the processes of transcription and translation, which are both involved in protein synthesis. Transcription is the synthesis of a mRNA molecule from a DNA template while translation is the synthesis of a polypeptide/amino acid sequence from a mRNA template.

The following DNA molecule was given as follows; TAC TTC AAA ATC. Firstly transcription will synthesize an mRNA molecule based on complementary base pairing rule. The resulting mRNA will be: AUG AAG UUU UAG

Next, the process of translation which involves the synthesis of an amino acid sequence from mRNA. Using the genetic code will produce the following:

Methionine- Lysine- leucine- stop

Answer:

The purpose of the crest was to provide a surface for masticatory muscle attachment or insertion.

Explanation:

This crest is called the sagittal crest. It is present in extinct hominids, such as Australopithecus and Paranthropus, and can also be found in living animals such as gorillas or lions and some reptiles.

The sagittal crest is a bony structure that crosses the hominids´ skull longitudinally, and it is so well-developed that it stands out notoriously.

This crest, like others in the skulls, provides an attachment surface for many muscles. In the particular case of the sagittal crest, it is believed to provide an insertion area to mastication muscles.

It seems that Australopithecus had a special diet composed of tough items. The hominid probably needed to strong bite while eating. The strong jow muscles gave them the possibility to bite but needed a wide area for insertion. The sagittal crest provided that wide surface. There was a direct relationship between the size of the crest and the muscle mass. The bigger the crest was, the more developed the muscle was.

It is believed that in living animals, such as gorillas, the development of the crest in males is for sexual selection and reproductive success. The bigger the crest is, the more attractive the male is, and the more chances to be selected by the female to mate it will have. Some hypothesize that the development of the crest in Australopithecus could also be related to sexual selection.

Two different routes by which blood in the left side of the heart can get to the right side of the heart in circulatory system are the right ventricle and the right lung

The circulatory system is involve in for delivering nutrients, oxygen, and hormones and removing waste from the body.

The major components are the heart, blood, and blood vessels.

The heart is a muscular organ present in the chest pumps blood continuously around the body through the network of blood vessels.

The heart ensures every cell of the body receives nutrients and oxygen through the blood.

Blood is a fluid connective tissue, the major types of cells are red blood cells, white blood cells or leukocytes, and platelets or thrombocytes.

The function of blood include transporting oxygen and nutrients, removing waste, protecting our immune system, and maintaining  homeostasis.

Answer:

Forms sedimentary rocks

When any organism die, it releases carbon dioxide during decay, forms sedimentary rocks as well as fossil fuels. The correct option is D.

The carbon cycle is nature's way of recycling carbon, which travel from the atmosphere into lifeforms on Earth and then back into the atmosphere.

During decay, formation of sedimentary rocks, and formation of fossil fuels, carbon re-enter the environment after an organism die.

The carbon cycle exemplifies how carbon moves among various reservoirs on Earth. This cycle is crucial for keeping Earth's breathable atmosphere and carbon balance.

Without carbon, there wouldn't be any life on Earth. This is largely attributable, in part, to carbon's ability to readily form bonds with other atoms, which allows for greater flexibility in the form and function of biomolecules such as DNA and RNA.

Thus, the correct option is D.

✅ C. amoeba

just took the test

The organism that is an animal-like protist is the amoeba.

Amoebas are a group of single-celled organisms belonging to the phylum Amoebozoa. They are classified as protists, which are a diverse group of eukaryotic microorganisms that do not fit into the categories of plants, animals, or fungi.

Amoebas are characterized by their ability to move and change shape through the use of pseudopodia, which are temporary extensions of their cell membrane. These extensions allow amoebas to engulf and surround their food, typically consisting of bacteria, algae, or other small organisms.

Amoebas are single-celled protists that move using pseudopodia, which are temporary extensions of their cell membrane. They are classified as animal-like because of their ability to move and capture food in a similar manner to animals. Amoebas belong to the phylum Amoebozoa and are commonly found in freshwater and soil environments.

b. diffusion and osmosis across semi-permeable membranes

Explanation:

ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.

In the above options, the processes listed as follows require ATP to occur:

- The active transport of glucose from the small intestine to the blood

- The movement of the flagella of sperm for motility

- Exocytosis of waste substances across a semi-permeable membrane

However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.

Answer:

(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.

Explanation:

Considering the fact that there may be some other causes of periodontitis aside from the lowered levels of the enzyme.

Therefore, should there be some other causes of periodontitis, hence, it can be concluded the process of restoring the enzyme to normal levels might not be sufficient for eliminating periodontitis.

Hence, the author's argument is solely based on this assumption, and option. Hence, option (E) is the correct answer.
