what is unique about HIV?
Answer:
HIV is called a retrovirus because it works in a back-to-front way. Unlike other viruses, retroviruses store their genetic information using RNA instead of DNA, meaning they need to 'make' DNA when they enter a human cell in order to make new copies of themselves.

You are learning about mimicry in entomology. Which microscope would be best to look at the wings of two different butterflies to determine which is a Monarch Butterfly and which is a Viceroy Butterfly?
The greatest tool to use to compare the wings of two distinct butterflies and identify which is a Viceroy butterfly and which is a Monarch butterfly is a scanning electron microscope, hence option C is correct.
What is a scanning electron microscope?A focused stream of electrons is used by an electron microscope known as a scanning electron microscope (SEM) to scan a sample's surface and produce images of the material.
Various signals that reveal information about the sample's surface topography and composition appear as the electrons make contact with the sample's atoms.
The electron beam is scanned using a raster scan pattern, and an image is produced by fusing the position of the beam with the intensity of the signal that is detected.
Therefore, to compare the wings of two distinct butterflies and identify which is a Viceroy butterfly and which is a Monarch butterfly with a scanning electron microscope, hence option C is correct.

12. During the process of photosynthesis, energy from the Sun is converted into A. chemical energy in the bonds of inorganic molecules B. chemical energy in the bonds of organic molecules C. enzymes used to produce inorganic molecules D. enzymes used to produce organic molecules
Eliminate and explain pls
Answer:
Explanation:
A. Inorganic molecules are rarely present in the human body, and the products of photosynthesis only contain one inorganic molecule (a molecule without carbon), [tex]O_2[/tex].
B. This is correct because when looking at the photosynthesis equation you have [tex]H_2O[/tex] + [tex]CO_2[/tex] + Sunlight = [tex]C_6H_{12} O_6[/tex] + [tex]O_2[/tex] Now illustrating this conversion, the [tex]O_2[/tex] Was made from the breaking of the bonds, so no new bonding was formed, this is the only inorganic molecule. The organic molecule, glucose, or the C6H12O6, was made combining the ingredients H2O and CO2. In order to combine the components used to make the glucose, the energy from the sun helps with the exchange of electrons and facilitates the bonding to make the organic molecule glucose.
C. Sun energy can not be converted into energy used to create enzymes
D. Same as C

explain the effect of germination on pea seed respiration
Answer:
"The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is higher because the cells are growing/going through mitosis which requires energy/ATP in order to be carried out which is generated through the process of cellular respiration."

Answer:
No, Her parents carried it from other family members because brown is dominant
Explanation:
hope this helps
No, Her parents carried it from other family members because brown is dominant Dad has blue eyes and Mom has blue eyes. Their daughter, Bonnie, has brown eyes.
What is a phenotype of eye color?The allele for green eyes is always dominant over the allele for blue eyes, which is always recessive. You will have brown eyes if at least one of your two copies is brown (Bb), which is what dominance signifies.The allele for brown eyes is the most dominant one and is always dominant over the other two alleles.
Geneticists refer to the various eye color gene variants as B for brown and b for blue, if your mom has blue eyes, your dad has brown eyes, and you have brown eyes.
Therefore, a quarter of the offspring will be born with blue eyes, and three-quarters will be born with brown eyes if both parents have brown eyes but also carry the gene for blue eyes.
Therefore, No, Her parents carried it from other family members because brown is dominant Dad has blue eyes and Mom has blue eyes. Their daughter, Bonnie, has brown eyes.

differences between the structure of the wall of the stomach and the structure of the wall of the ileum
Answer:
Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.
wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.

Pharmacodynamic tolerance involves changes in _____________ while metabolic tolerance involves changes in _____________. Group of answer choices A. enzymes / neurons B. neurons / enzymes C. brain / neuron D. neuron / brain
Answer:
B
Explanation:
Pharmacodynamic tolerance involves changes in neurons, while metabolic tolerance involves changes in enzymes.
What is pharmacodynamics?
"Pharmacodynamic interactions" are interactions in which substances directly affect one another's effects. Sedatives, for instance, typically potentiate one another.
Neurons are the cells of the nervous system the cell plants are branch-like structures like the roots of a plant, they contain absorb information using electrical impulses and transport it into different areas of the brain.
The central nervous system contains the brain and the hypothalamus, and the peripheral nervous system contains all the neuron cells.
Therefore, while metabolic tolerance affects changes in enzymes, pharmacodynamic tolerance involves changes in neurons.

the sequence of events that produces another generation of organisms.
The sequence of events which produces another generation of organisms is called as the Life cycle.
What is Life cycle?Life cycle is defined as the series of changes which members of a species undergo from the beginning of a given developmental stage to the beginning of the same developmental stage in a subsequent generation.
In many simple organisms including bacteria and various protists, the life cycle is completed within a single generation where an organism begins by fragmentation of an existing individual and the new organism grows to maturity which then splits into two new individuals, so the life cycle is complete.
Thus, the sequence of events which produces another generation of organisms is called as the Life cycle.
