Explanation:

Answer: promoters

Explanation:

Promoters are DNA sequences that direct RNA polymerase to the initiation site. Promoter sequences are simply DNA sequences that helps in defining where the gene transcription by RNA polymerase will start.

Promoter sequences are located directly upstream and are an important part of the expression vectors as the binding of DNA to the RNA polymeras are being controlled by them.

Answer:

nutrients

Explanation:

A natural process in which elements are continuously cycled in various forms between different compartments of the environment (e.g., air, water, soil, organisms).

Carbon, Nitrogen, and Phosphorus are examples of nutrients. Thus, the correct option for this question is B.

Nutrients are important for organisms in order to furnish the source of energy that is ultimately required by the animals for the accomplishment of metabolic functions like tissue repair, building, and growth of cells, reproduction, etc.

These nutrients form complex compounds like carbohydrates, fats, vitamins, minerals, proteins, etc. The function of each complex compound is very specific. For example, carbohydrate is known as energy-deriving molecules which deliver immediate energy to the cells of living organisms, proteins are required for cell and tissue repairment, etc.

Therefore, carbon, Nitrogen, and Phosphorus are examples of nutrients. Thus, the correct option for this question is B.

Answer:

C

Explanation:

The correct answer here would be that the peptidyl transferase breaks the bond between the growing polypeptide chain and the tRNA in the P site, but there is no new charged tRNA in the A site, which results in the termination of translation and release of the polypeptide.

The translation process stops when the stop codon in the mRNA being translated enters site A in the translation complex. When this happens, the release factor recognizes the stop codon and makes the enzymes that form peptide bonds to add water to the last amino acid on the chain.

The addition of water leads to the breaking of the peptide bond by peptidyl transferase, causing the separation of the polypeptide chain from the tRNA and the eventual release of the protein.

Hence, the correct option would be C.

the two main reasons for variation between organisms of the same species are

Inheritance and mutation

as in same species no of chromosomes are same but variation occurs in genetic sequence so variation occurs in organisms.

Answer:

during cell division (meiosis)

Explanation:

During meiosis, DNA double-strand breaks (DSBs) between homologous chromosomes are induced and, after the exchange of DNA pieces, breaks are jointed by specific DNA-repair enzymes (such as DNA glycosylases). DSBs can be repaired by two different mechanisms: non-homologous end-joining (NHEJ) and homologous recombination (HR), which have different functional consequences. These mechanisms of recombination have potential for increasing the genetic variation since the resulting gametes will contain a different set of chromosome fragments.

Explanation:

Answer:

Green house gases like carbon dioxide, carbon monoxide, carbon tetra chloride, methane, sulphur dioxide, nitrogen dioxide, etc .. are responsible for Global warming and Chlorofluorocarbons and nitrides of oxygen are responsible for Ozone layer depletion.

Explanation:

One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, or CO2.

Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).

Answer:

This is an example of replication.

Explanation:

Getting a similar outcome when a trial is rehashed is called replication. Replication is significant in science so researchers can check their work. The consequence of an examination isn't probably going to be very much acknowledged except if the examination is rehashed ordinarily and a similar outcome is constantly acquired.

Hence, This is an example of replication.

Answer: c. replication

Answer:

Increase volume; decrease osmotic concentration

Explanation:

Nephron is the functional unit of a kidney.

The juxtamedullary nephrons is responsible for the development of the osmotic gradients. The osmotic gradient helps in ensuring the urine is well concentrated and helps in adequate water reabsorption.

The absence of juxtamedullary nephrons affect the volume of urine and its osmotic concentration by Increasing the volume and decreasing the osmotic concentration.

Answer:

Interaction between hydrophobic (nonpolar) amino acid side chains is due to hydrophobic interactions.

Repulsion between negatively charged backbone of DNA double helix is due to electrostatic repulsion forces.

Interaction between water and carbonyl oxygen of guanine is due hydrogen bonding

Explanation:

The hydrophobic effect refers to the tendency of non-polar substances forms aggregates in an aqueous solutions in order to avoid interactions with water molecules. This results in a favorable entropy increase.

For non-polar amino acids, hydrophobic interactions are important in stabilizing their structure wherein they are densely packed within the core of a protein while those with with polar groups are found in the exterior.

The phosphate backbone of DNA is negatively charged. Since like charges repel, therefore, electrostatic repulsion forces of the ions are responsible the repulsion of the backbone DNA double helix.

Hydrogen bonds are formed between electronegative oxygen atoms and hydrogen atoms of neighboring molecules due to the partial negative and positive charges on each of the atoms.

This hydrogen bonding is responsible for the interaction between water and carbonyl oxygen of guanine as the hydrogen atoms of the water molecules are attracted to the oxygen atoms of the guanine molecules due to the partial charges on each of the atoms.

Answer: Organization

Explanation: A piece of petrified wood was once part of a living organism that has had its tissues replaced by minerals. Which property of life will still be present in the wood?

a) homeostasis

b) response to stimuli

c) growth and reproduction

d) organization

e) metabolism

A petrified wood has had its organic remains or tissues replaced by minerals, a start to the slow process of being replaced with stone. The property of life still present in the wood would be that of organization which simply indicates that the petrified wood are made of cells--the most basic unit of life. As such, it still remains a highly organized, specialized entity with coordinated parts.

Explanation:

Answer: Only after the first cytokinesis, when the daughter cells of meiosis I are fully separated, are the cells considered haploid. Following this first division, the cell begins meiosis II with prophase II, making this the first haploid meiotic stage.

Explanation:

The stage of meiosis is when the daughter cells first become haploid is meiosis I, after cytokinesis.

Meiosis is a process of cell division that occurs only in germ cells, during the process of reproduction. It is divided into meiosis I and meiosis II. The process completes in eight stages.

After the process of cytokinesis, the daughter cells become haploid and have their chromosome paired up.

Thus, Meiosis I, the first step of meiosis after cytokinesis, is when the daughter cells initially become haploid.

Answer:

Independent variable: varying amounts of light

Dependent variable: plant growth

Explanation:

The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.

The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).

Answer:

These are the thylakoids

Explanation:

The thylakoids which contains the chlorophyll is  the primary site of photosynthesis. It  is covered by layers of cell called the thylakoid membrane.These are the actual site for light dependent reaction.This membrane contains both photosytem I and ii, ATPase enzymes, and Cytochrome b6f complex.While the photosystem i and ii transfer elecrons during photosynthesis, the ATPase enzyme control the catalysis the phosphorylation of ADP to ATP needed for the light independent stage, the Cytochrome  proteins  acts as the ETC. involved in the transfer of electron during light dependent stage.

When thylakoids are packed together in disc shape they are refer to as Grana,(singular -granum).Each  grana are linked together by intergrana.Thus two or more grana are linked by intragrana to form a single photosynthetic functioning unit.The entire structure is bath continuously by the fluid medium-Stroma.

Their stacked and  disc shape is to increase the surface area available to accommodate enough  ETC, needed to transport electron for chemiosmosis needed for photosynthesis.

Answer:

Evolution

Evolution is considered a unifying theory of biology. It explains the unity and diversity of life.

Answer:

Charles Darwin's work followed the rules of hypotheses creation and testing.

In order to prove a scientific suspicion, a true scientist has to follow the above methods.

So Darwin probably theorized that the offspring of certain living entities were by either environmental conditioning or by natural selection different genetically from their parent.

He tried this hypothesis over time and using the results he got, modified his theory.
