1 a What substances must a plant take in, in order to carry
on photosynthesis?
b Where does it get each of these substances from?
Answer:
a .carbon dioxide(Co2) and water (H2O)
b. air and soil
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Long Answer:
What is RNA? How is RNA produced?RNA is a nucleic acid that is single stranded and comparable to DNA. DNA is also known as deoxyribonucleic acid, whereas RNA is short for ribonucleic acid. The word "ribo" in the name refers to the kind of sugar that makes up the nucleic acid backbone. Although RNA comes in a variety of forms, the three primary kinds all play crucial roles in the cell's translation of the DNA code into functional proteins. A copy of a gene's DNA sequence, known as messenger RNA, exits the cell's nucleus. A ribosome converts the sequence in the mRNA into a polypeptide (unprocessed protein). RRNA is used to make ribosomes (ribosomal RNA). The polypeptide's building blocks, amino acids, are joined to tRNAs (transfer RNAs). Transfer RNAs ensure that the right amino acid is delivered to the polypeptide that the ribosome is producing by matching with their complement bases on the mRNA.
What is transcription in biology?Transcription is the biological process through which a complementary RNA strand is created using DNA as a template. This is the initial phase of either the creation of proteins or the transfer of information inside a cell. Genetic information is stored in DNA, which is subsequently used to transmit it to RNA during transcription and then control the synthesis of proteins during translation. Messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA are the three forms of RNA that may be produced (rRNA). Pre-commencement, initiation, elongation, and termination are the four phases of transcription. By attaching to a promoter region at the 5' end of a DNA strand, the RNA polymerase subunit starts pre-initiation, also known as template binding. The enzyme can access the template strand because the DNA strand is denatured, which separates the two complementary strands. Partner strand refers to the opposite strand. The DNA strand's promoter sequences are essential for the effective start of transcription.The identification of some of these motifs, including TATAAT and TTGACA in prokaryotes and TATAAAA and GGCCAATCT in eukaryotes, has been determined. Promoter sequences are particular sequences of the ribonucleotide bases making up the DNA strand (adenine, thymine, guanine, and cytosine). These patterns are referred to as cis-acting elements. For RNA polymerase to more easily attach to the promoter region in eukaryotes, an extra transcription factor is required.
What is the process of transcription and translation within biology? What are some examples?First, the double-stranded DNA unzips, and the mRNA strand generated (the sense transcript) will be complementary to the original strand of DNA (therefore containing particular codons/triplets of bases) and connected to the DNA through hydrogen bonds between complementary bases. Following this, the mRNA generated will separate from the DNA, exit the nucleus through a hole, and enter the cytoplasm. Then it will connect to a ribosome, which is where translation takes place. Specific amino acids are delivered to the ribosome via tRNA anticodons that are corresponding to the mRNA codons (as they have specific amino acid binding sites). When two tRNA molecules are present in the ribosome, they keep the amino acids in place while a condensation process creates peptide bonds between them to form a dipeptide. This procedure is repeated to create a polypeptide chain or protein by condensation polymerization, which has a certain primary structure because it contains a particular amino acid sequence or order. The translation step is now. Due to specific interactions (such as ionic bonds, disulfide bridges, covalent bonds, and hydrogen bonds) between particular R groups, this structure folds in a specific way, resulting in the secondary structure, which can be an alpha helix or a beta pleated sheet, and then the functional tertiary (3D) protein, which has a specific structure and consequently a specific function. As a result, it influences a cell's structure and functionality, leading to its specialization. A quaternary structure can be created by making further changes to the tertiary structure. This happens when the tertiary structure is linked to another polypeptide chain (for example, collagen is a fibrous protein made up of three polypeptide chains wound around one another and joined by hydrogen bonds) or another non-polypeptide group via covalent bonding or London forces/permanent dipole forces/ion dipole forces to form a conjugated protein (for instance, the conjugated globular protein haemoglobin contains the prosthetic group Fe2+). Thus, some proteins with a particular structure and consequent function are generated during translation. These proteins alter the structure and function of the cell, leading to its specialization.

A scientist wants to test the effect of water temperature on the success of developing frog embryos. The scientist monitors developing embryos in different water temperatures and counts the number of embryos that mature into tadpoles.
Why should the scientist keep all variables except water temperature constant?
to ensure at least some embryos develop into tadpoles
to protect the developing embryos
to test multiple variables at once
to ensure that the results only reflect changing temperature
The scientist should eep all variables except water temperature constant because to ensure that the results only reflect changing temperature. Thus, the correct option is D.
What is Embryo?An embryo may be defined as an unborn or unhatched offspring in the process of development. It is also characterized as the early stage of the development of multicellular organisms.
Here, scientists should keep all the variables except water temperature constant because they are analyzing the effect of only water temperature on the growth and maturation of a frog's embryo into mature tadpoles.

a carbohydrate 7 monomers long has how many glycosidic bonds?
The bond between monomers of carbohydrates, e.g. glucose and fructose is a glycosidic bond-forming in this case a sucrose molecule (disaccharide). A glycosidic linkage is a C-O-C bond (ether). The underlying reaction is a condensation reaction where 1 OH- and 1 H+ are split off resulting in the formation of H2O.

What is respiration?Inhalation:
On inhalation, the pressure in the alveoli is high, hence the Oxygen diffuses to the nearby blood through the membrane.
Exhalation:
It is the process in which a person releases the air collected in the lung. During exhalation, the pressure in the alveoli is low, hence the carbon dioxide present in the blood is diffused out into the alveoli.
Therefore, the expandable structure of alveoli helps the respiratory system to follow its function.

how does research in Social Psychology help to understand why sometimes our actions (behavior) do not match our attitudes (feelings often influenced by our Beliefs
Answer:
According to psychologist Gordon Allport, social psychology uses scientific methods "to understand and explain how the thoughts, feelings, and behavior of individuals are influenced by the actual, imagined, or implied presence of other human beings." What social psychology does is that it teaches us how people's social behavior is, and how we can match certain aspects of our emotions to uncalled attitudes. For example, someone may lash out at someone they truly love when they don't mean it, solely because they are upset. Social psychology can teach us how our feelings are coordinated with our beliefs and how we can react to them appropriately.
