A mother has one allele for dimples and one allele for no dimples. What is the
probability that she produces a gamete with the allele for dimples?
A mother with a heterozygous genotype for dimples (Dd) has a 50% chance of passing the allele for dimples to her gamete.
The question is asking about the probability that a mother who has one allele for dimples and one allele for no dimples will pass on the allele for dimples. In genetic terms, dimples can be a dominant trait, and we might represent the allele for dimples as 'D' and the allele for no dimples as 'd'. If a mother's genotype is Dd, which means she is heterozygous for the trait, she has a 50% chance of passing on the D allele and a 50% chance of passing on the d allele to any given gamete (egg cell).
How does photosynthesis interconnect to the big idea of the cell
Answer:
Photosynthesis traps free energy present in sunlight that, in turn, is used to produce carbohydrates from carbon dioxide. Cellular respiration and fermentation harvest free energy from sugars to produce free energy carriers, including ATP. The free energy available in sugars drives metabolic pathways in cells. Photosynthesis and respiration are interdependent processes.
Cells and organisms must exchange matter with the environment. For example, water and nutrients are used in the synthesis of new molecules; carbon moves from the environment to organisms where it is incorporated into carbohydrates, proteins, nucleic acids or fats; and oxygen is necessary for more efficient free energy use in cellular respiration. Differences in surface-to-volume ratios affect the capacity of a biological system to obtain resources and eliminate wastes. Programmed cell death (apoptosis) plays a role in normal development and differentiation (e.g. morphogenesis).
Explanation:
Autotrophic cells capture free energy through photosynthesis and chemosynthesis.
Chemosynthesis captures energy present in inorganic chemicals.
Membranes allow cells to create and maintain internal environments that differ from external environments. The structure of cell membranes results in selective permeability; the movement of molecules across them via osmosis, diffusion and active transport maintains dynamic homeostasis. In eukaryotes, internal membranes partition the cell into specialized regions that allow cell processes to operate with optimal efficiency. Each compartment or membrane-bound organelle enables localization of chemical reactions.
Organisms also have feedback mechanisms that maintain dynamic homeostasis by allowing them to respond to changes in their internal and external environments. Negative feedback loops maintain optimal internal environments, and positive feedback mechanisms amplify responses. Changes in a biological system’s environment, particularly the availability of resources, influence responses and activities, and organisms use various means to obtain nutrients and get rid of wastes. Homeostatic mechanisms across phyla reflect both continuity due to common ancestry and change due to evolution and natural selection; in plants and animals, defense mechanisms against disruptions of dynamic homeostasis have evolved. Additionally, the timing and coordination of developmental, physiological and behavioral events are regulated, increasing fitness of individuals and long-term survival of populations.

What is produced when sugar is digested in an animal cell
Answer:
Carbon Dioxide
Explanation:
Glycolysis is the first step where glucose is broken down into two molecules. This occurs in the cytoplasm of the cell. By the end of the process, a molecule of glucose is broken down to carbon dioxide.
Final answer:
Sucrose is hydrolyzed into glucose and fructose, while lactose is hydrolyzed into glucose and galactose by specific enzymes. Many adults have difficulties digesting unfermented dairy due to insufficient lactase production.
Explanation:
Sucrose (table sugar) is hydrolyzed into glucose and fructose by the enzyme sucrase. Lactose found in milk is hydrolyzed into glucose and galactose by the enzyme lactase. The majority of the adult population have problems digesting unfermented dairy because they cannot produce sufficient amounts of the enzyme lactase - a condition called lactose intolerance.

What is The Convention on Biological Diversity?The Convention on Biological Diversity is an international treaty that aims to conserve biodiversity, sustainably use its components, and ensure the fair and equitable sharing of benefits arising from the use of genetic resources.
However, a limitation of the convention is that it does not include bacteria, fungi, or protists in its definition of biodiversity. This is because these organisms are not always considered in the same way as plants and animals, which are more visible and easily studied.
Bacteria, fungi, and protists play crucial roles in ecosystems and contribute to biodiversity, but they are often overlooked or undervalued compared to other groups of organisms.
Therefore, the Convention on Biological Diversity has been criticized for not adequately addressing the conservation of these groups of organisms.

Describe the general structure of the monomers
Answer:
The monomer is an amino acid, and I will describe it below. :)
Explanation:
Rubisco is an enzyme found in plants, and its job is to fix carbon. Since we know it is an enzyme, we also know it is a protein since pretty much all enzymes are proteins. The monomer of proteins is the amino acid.
The structure of an amino acid looks like this (see the picture). On one side we have a basic amino group, on the other side we have an acidic carboxyl group. The combination of the amino group and acid group gives us the name amino acid. Also notice that there is the R group. Each amino acid has the same basic structure (with the amino group and carboxyl group), but the unique R group is what gives the particular amino acid its unique characteristics. There are about 20 different kinds of R groups which is why there are 20 different types of amino acids.
So, having a non-polar R group would allow it to interact with a hydrophobic amino acid in another Rubisco molecule.
Monomers are the basic unit of polymers. They are composed of carbon, oxygen, and hydrogen atoms, joint by covalent bonds. There are different monomers which vary in structure, such as nucleotides and amino acids.
-------------------------------------------------------------------
Monomers are the basic unit of polymers. When many monomers join through chemical bonds, through the polymerization process, they form a polymer.
There are many types of monomeric molecules. To name a few, we can mention
Monomer Polymer
Monosaccharide ⇒ CarbohydratesFatty acid ⇒ LipidsAmino acid ⇒ ProteinsNucleotide ⇒ Nucleic acids
Monomers are organic molecules of reduced molecular mass. They are basic units relatively simple, with a defined structure.
Monomers are composed of carbon, oxygen, and hydrogen atoms, which establish covalent bonds.
For instance,
Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.Amino acids are monomers composed of a central carbon, one hydrogen atom, one carboxyl group, one amine group, and one R group. The composition of the R group is what makes them different from each other.Every monomer has a free H atom and a hydroxyl group (-OH) in the extremes. When two monomers get together, the H atom and the -OH join to form a water molecule, which is released. The result is a polymer of two monomers and H₂O.

D. The response of a plant to gravity
Gibberellins are plant hormones involved in various growth processes, including seed germination. Therefore, the use of gibberellin would most likely be seen in the development of new seedlings.
Explanation:Gibberellins are a category of plant hormones that play an essential role in different growth processes, including seed germination, stem elongation, and leaf and fruit development. In light of these functions, the option A. The development of new seedlings most likely involves the hormone gibberellin. During the seed germination process, gibberellins stimulate the growth and development of seedlings by helping in the mobilization of stored food in the seed and sending signals for the seed to break dormancy.

#SPJ12
The situation that most likely involves the hormone gibberellin is A. The development of new seedlings.
Gibberellins are plant hormones that stimulate several processes, including shoot elongation, seed germination, and fruit and flower maturation. Specifically, gibberellins break dormancy in seeds, which is typically a state of inhibited growth and development.
These hormones do so by activating the transcription of genes encoding for enzymes like amylase which break down stored starches in the seed into simpler sugars necessary for the growth of the seedling. Moreover, gibberellins promote the cell elongation of young roots during the germination process.
When water is available, it activates gibberellins, leading to seed germination; conversely, the absence of water leads to increased abscisic acid which inhibits gibberellins and thus prevents germination.
Which of the following statements is true of the process shown below? A. The cells formed at the end of the process only have half of the chromosomes as the original cells. B. The cells formed at the end of the process are identical to the original cells. C. The cells formed at the end of the process do not contain any of the genetic material from the original cells. D. The cells formed at the end of the process contain the same number of chromosomes as the original cells.
The statements is true of the process shown below is that the cells formed at the end of the process only have half of the chromosomes as the original cells. Thus, option A is correct.
Where the formation of cell takes place?The cells formed at the end of the process are identical to the original cells. The cells formed at the end of the process do not contain any of the genetic material from the original cells. When a cell undergoing cellular division identifies that a chromosome misalignment had taken place the cell cycle stops until the error it's corrected.
Option two of the question states that the cell cycle will proceed uncontrollably, this is not the case for the error at hand. Although this can be a problem for cells and leads to the appearance of cancer, it is not caused by chromosome misalignment.
The stop or delay in the cell cycle is what normally takes place in these situations. This stoppage is done by the spindle checkpoint, which prevents duplicate chromosomes from separating.
Therefore, The statements is true of the process shown below is that the cells formed at the end of the process only have half of the chromosomes as the original cells. Thus, option A is correct.
