In which phase of the cell cycle is the DNA loose and not chromosomes?
Answer:
Interphase
Explanation:
During this phase, the DNA is uncoiled and called chromatin. A pair of centrioles are present (but inactive in the cytoplasm) and the nucleolus is visible. At this time the cell grows, the DNA replicates and organelles grow in preparation for cell division.
Hydrogen ions are important in the light-dependent reactions of photosynthesis because they produce a
difference in charge across the thylakoid membrane that allows
a. the production of ATP.
b. the release of water molecules.
c. light to enter the chloroplast.
d. the conversion of 3-carbon molecules into higher-energy forms.
Answer:
a. the production of ATP
Explanation:
Photosynthesis is type of biosynthesis that produces glucose from the reactants sunlight, carbon dioxide and water. It happens in two phases of the chloroplast, the light-dependent and light-independent reactions. In a light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths. Here,
Light energy stimulates photosystem complexes formed from chlorophyll. Photosystem II then absorbs and transfers light to a reaction core. Water undergoes hydrolysis or splitting to yield an electron, a proton (H+) and oxygen. energy is passed along the electron transport chain, where it forms builds up H+ and an electrochemical gradient in the thylakoid spaceThese protons pass through the ATPase enzyme embedded within the membrane, into the stroma, generating ATP from ADP.NADPH is generated from NADP+Which of these is an indicator of the age of a woody plant?

A cell turns glucose from the
food we eat into energy for our
body to use. What cell function
does this describe?

Answer:
[tex]\boxed {\boxed {\sf Cellular \ respiration}}\\[/tex]
Explanation:
The process of cellular respiration occurs in the mitochondria of cells. It goes through 3 stages: glycolysis, the citric acid/Krebs cycle, and the Electron Transport Chain.
The equation is:
[tex]C_6H_{12}O_6+6O_2 ->6CO_2+6H_2O+38 \ ATP[/tex]
In this aerobic process (requires oxygen), glucose (C₆H₁₂O₆) from the food animals eat or produced from photosynthesis and oxygen are converted into carbon dioxide, water, and useable energy (ATP).
So, the cell function described is cellular respiration.

Explanation:
Answer:
A topographic profile or topographic cut is a representation of the relief of the terrain that is obtained by cutting transversely the lines of a topographic map.
Explanation:
Each contour line can be defined as a closed line joining relief points at equal height above sea level. It is usually drawn on the same horizontal scale as the map, but the use of an exaggerated vertical scale is advisable to underline the elements of the relief. This can vary according to the slope and amplitude of the terrestrial relief, but is usually three to five times the horizontal scale.

Compare and contrast the two types of bonds
Answer:
An ionic bond is formed between a metal and a non-metal. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
Explanation:
There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.

Answer:
Acid end
Explanation:
The acid end of the pH scale contains solutions that have the most hydrogen ions.
A convenient scale for expressing the level of acidity or alkalinity of aqueous solutions is the pH or pOH scale . The pH of a solution is the negative logarithm to base 10 of the hydrogen ion concentration in the solution. The scale ranges from 1 to 141 is the lower limit and 14, the upper limitAcidic solution has a pH value less than 7. As pH decreases the hydrogen ions concentration increases.

Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins. Be sure to describe the steps in the process of protein synthesis. Use information from the lesson to support your response.
Answer:
The sequence of bases in a DNA molecule can determine the order of amino acids in a protein molecule. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene .
Explanation:
DNA is a genetic material that is made up of two polynucleotide chains.
The structure of a protein is determined by the structure of DNA :
DNA helps in protein synthesis by giving one template in it to produce the mRNA. So if there are any changes in the sequence of DNA, it will affect the protein sequence.
Process of protein synthesisThe process of protein synthesis happens in two phases:The first is transcription, in which the conversion of the DNA into mRNA happens.Transcription occurs in three steps, initiation, elongation, and termination.In the initiation, the DNA strands open up with the help of polymerase enzyme.In elongation, one template of the DNA acts as a template to produce mRNA. The mRNA produced.In the termination, the mRNA template is separated from the DNA and the termination code arrived.The second is translation, in which the mRNA is converted into protein.This is carried out in three steps, initiation, elongation, and termination.In the initiation, the ribosomal units combined with the mRNA.During the elongation, the ribosomal units continue to translate each codon.In termination, the stop codons are reached and there is no codons to translate so the process stop.Thus, that's how protein synthesis occurs.

What does the Teacher's Pet Video: Mitosis and Meiosis give as the main reason for the
production of haploid cells during meiosis?
because both the parents' and offspring's diploid cells will then be genetically identical to one
O because the two haploid cells will fuse together to make a new genetically different diploid cell
that will form the offspring
O because the sperm brings all of the father's genes to the egg allowing for the baby to have a
different number of chromosomes
O because the egg and the sperm will then be able to each form a new diploid offspring through the
process of meiosis
Answer:
The main reason for the production of haploid cells during meiosis is because the two haploid cells will fuse together to make a new genetically different diploid cell that will form the offspring.
Explanation:
In the context of sexual reproduction, meiosis is the process of cell division by which gametogenesis occurs. In this process, diploid cells are used to obtain haploid cells, called gametes.
The reduction of the chromosomal charge that occurs in meiosis is aimed at producing haploid cells —with half of the crosmosomes of a species— so that when the parents' gametes join, they form a diploide cell called zygote.
The zygote is the starting point for the development of a new individual, part of the offspring.
