Answer:

This question lacks options, options are: A) DNA replication is semiconservative. B) DNA replication is conservative. C) RNA synthesis is conservative. D) DNA replication is not conservative. The correct answer is A.

Explanation:

Watson and Crick proposed the semi-conservative hypothesis (later demonstrated by Meselson and Stahl in 1957), according to which new DNA molecules formed from an old one have an old and a new strand. This replication model assumed that the double helix DNA separates its two strands and each one serves as a template to synthesize a new strand following the complementary rules of nitrogenous bases. This model was called Semiconservative, since the two newly synthesized double helices have an old strand (an old half) and a new strand (a new half).

The process of the formation of new DNA from the older DNA is called replication.

The answer to the following question is semi conversation of DNA.

In the replication, there are two-strand in which one stand is template strand and the other stand is called leading strand. Both the strands act as a template strand and is being copied by the DNA polymerase.

These template strands formed the new DNA and joined it by the DNA ligase to complete it.

Hence, In DNA replication, the resulting daughter molecules contain one strand of the original parental DNA and one new strand. This phenomenon is known as semi-conservation.

Answer:

The correct answer is - fibrous, cartilaginous.

Explanation:

In the body, there are joints named after the type of tissue attached to them and these joints are:

1. fibrous joints - these are connected with dense connected tissues and called immovable or fixed joints.

2.cartilaginous joints - these are joined by cartilage tissue. These joints are also not able to move freely.

3. synovial joints are known as movable joints and can move freely. These are present in a fluid-filled capsule for better movement.

Answer:

Tracheal, vessel or vascular cells have one or more pores in their terminal walls. They reabsorb the common walls. They adopt a vertical position and are linked together forming a continuous tube or glass. They constitute the Xylem of angiosperms, plants that have flowers, and their function is to conduct water and other nutrients.

Explanation:

The vascular elements or vessels are specialized tracheids whose terminal walls are crossed by one or more pores; a vertical series of vascular elements that form a continuous tube is called a vessel. The tracheids are cells that conduct water and salts of the xylem, through which the raw sap circulates. It is typical of gymnosperms. The tracheids are unicellular, very elongated and with numerous simple, areolate pits, through which they intercommunicate.

C. Natural disaster is a density-independent factor affecting population growth. Density-independent factors are those that affect the population irrespective of the population size or density.

Natural disasters such as floods, hurricanes, earthquakes, and wildfires can reduce population sizes regardless of how many individuals were present in the population before the disaster occurred. The other factors listed - competition, disease, and predation - are all density-dependent factors, which means that they become more significant as the population size or density increases.

Competition is an example of a density-dependent factor, as it increases as the population size increases. As more individuals compete for limited resources such as food, water, and shelter, the rate of population growth slows down.

Disease is another density-dependent factor, as it spreads more easily in crowded populations where individuals are in close contact with one another.

On the other hand, natural disasters such as floods, hurricanes, and wildfires are examples of density-independent factors. These events can affect a population regardless of its size, and they can cause significant decreases in population size.

Predation can be both a density-dependent and density-independent factor. In some cases, predation can increase as the population size increases, making it a density-dependent factor. However, predators can also reduce the population size through random hunting or selective hunting of weaker individuals, making it a density-independent factor.

Understanding the factors that affect population growth is important for predicting and managing population sizes in both natural and human-made ecosystems.

Answer:

Nitrogenous

Explanation:

Transfer RNA, also known as tRNA, is one of the three types of RNA. It is involved in the translation process. The shape of the tRNA allows it to be a very important component of the translation process.

The morphological structure of the tRNA is in such a way that a sequence of nitrogenous bases called ANTICODON attach to one of its ends while an amino acid is attached to the other end. This way the tRNA molecule is able to read the mRNA codon using its anticodons and carry the corresponding amino acids.

N.B; the anticodons are composed of three nitrogenous bases just like codons. Codons are complementary to anticodons.

Answer:

D. Adenosine DIPHOSPHATE

Explanation:

ATP is hydrolysed to ADP in the reaction ATP+H20->ADP +Pi + energy

When Adenosine Triphosphate is used, it breaks down into Adenosine Diphosphate.

Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atoms of ribose. The diphosphate group of ADP is attached to the 5’ carbon of the sugar backbone, while the adenine attaches to the 1’ carbon.

ADP can be interconverted to adenosine triphosphate (ATP) and adenosine monophosphate (AMP). ATP contains one more phosphate group than does ADP. AMP contains one fewer phosphate group. Energy transfer used by all living things is a result of the dephosphorylation of ATP by enzymes known as ATPases. The cleavage of a phosphate group from ATP results in the coupling of energy to metabolic reactions and is a by-product of ADP.ATP is continually reformed from lower-energy species ADP and AMP. The biosynthesis of ATP is achieved throughout processes such as substrate-level phosphorylation, oxidative phosphorylation, and photophosphorylation, all of which facilitate the addition of a phosphate group to ADP.

Answer: They don’t have microvili because they don’t need it.

Explanation:

Animal cells have this because it increase surface area and helps absorb food and water molecules.

Plant cells do not have microvilli because they do not require the same type of surface area enlargement as animal cells.

Microvilli are small, finger-like projections that extend from the surface of animal cells. They help to increase the surface area of the cell, which is important for functions such as absorption and secretion.

Whereas plant cells have a rigid cell wall that provides structural support and protection. They have evolved unique structures to meet their specific needs, such as chloroplasts for photosynthesis and a cell wall for support and protection.

So, the absence of microvilli in plant cells is not a disadvantage since they do not require the same surface area enlargement as animal cells.

Therefore, the absence of microvilli in plant cells is due to their unique structural and functional needs.

Answer:

Extrachromosomal or cytoplasmic inheritance

Explanation:

Extrachromosomal or cytoplasmic inheritance refers to hereditability transmission controlled by cytoplasmic genes.

This form of inheritance lays in genes that are out of the nucleus. Information for some characters is placed in organelles in the cytoplasm, such as mitochondria and chloroplasts. These organelles have a well-defined portion of the total cellular genome.

Although mitochondrial inheritance is mostly maternal, recent studies have demonstrated that it might also be paternal.

Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.
