Which statement about luminosity is NOT true?
A. It is commonly measured in watts.
B. It is valued at 1 for our sun.
C. It stands for the total energy output of a star
D. It increases from top to bottom on an H-R diagrams
Answer: D. It increases from top to bottom on an H-R diagrams
Luminosity is defined in the wordbook as brightness of a celestial object. In astronomy, it stands for the total amount of energy emitted per unit time by a star, so C. is correct. It is measured in joules per second or watts so A is correct also. It is B, valued at 1 for our sun.
In an H-R diagram, the energy of a star is plotted on the vertical axis. The lower or more negative the measure, the brighter the star, D is therefore not true.
In plants, the cell wall forms as a young plant secretes polysaccharides onto the outer surface of its plasma membrane. Being thin and pliable, this primary wall allows the cell to enlarge and change shape. In mature woody plants, cells in some tissues deposit material onto the primary wall's inner surface. Why doesn't this secondary wall form on the outer surface of the primary wall?
The secondary cell wall is a structure found in many plant cells, located between the primary cell wall and the plasma membrane. The cell starts producing the secondary cell wall after the primary cell wall is complete and the cell has stopped expanding.
Secondary cell walls provide additional protection to cells and rigidity and strength to the larger plant. These walls are constructed of layered sheaths of cellulose microfibrils, wherein the fibers are in parallel within each layer. The inclusion of lignin makes the secondary cell wall less flexible and less permeable to water than the primary cell wall. In addition to making the walls more resistant to degradation, the hydrophobic nature of lignin within these tissues is essential for containing water within the vascular tissues that carry it throughout the plant.
The secondary cell wall consists primarily of cellulose, along with other polysaccharides, lignin, and glycoprotein. It sometimes consists of three distinct layers - S1, S2 and S3 - where the direction of the cellulose microfibrils differs between the layers.
Answer:
The secondary wall form on the outer surface of the primary wall due to presence of middle lamella.
Explanation:
Middle lamella is present between the primary walls of the adjacent plant cells. Middle lamella is a sticky layer that serves to cement the adjacent plant cells together.
Due to the presence of stick middle lamella towards the outer side of the primary cell wall, the deposition of material to form the secondary cell wall occurs towards the inner side of the primary cell wall only.
The liver can convert _____ into glucose that can be released into the bloodstream or stored as glycogen. vitamin d lactate atp fatty acids
The liver can convert lactate into glucose that can be released into the bloodstream or stored as glycogen.
Answer: Option B
Explanation:
The lactate in food is usually transported to the liver where the process of gluconeogenesis takes place, this process produces glucose that can be used in the glycolysis and the citric acid cycle to produce ATP that is the energy required for the cell to carry out various metabolic activities. Glucose is the major source of energy for any cell , any other forms of carbohydrates must be first converted to glucose to enter into the energy cycle.
Which form of prevention takes place after the precursors of disease interact with the host?
Secondary prevention is the type of prevention that takes place after the precursors of disease have interacted with the host. This often involves interventions such as vaccination, which induce immunological memory, and measures taken during the period of decline to prevent secondary infections.
Explanation:The form of prevention that takes place after the precursors of disease interact with the host is called secondary prevention. This falls in the phase of illness where symptoms have appeared and intervention is required to halt the process of the disease. A primary example of secondary prevention in action is the vaccination program. With vaccinations, your body generates immunological memory, allowing you to combat the disease more vigorously upon exposure in the future, because it can mobilise a strong secondary response.
Secondary prevention strategies also include actions during the period of decline, where the number of pathogens starts to decrease along with symptoms. Due to the immune system having been busy fighting off the primary infection, this period can leave an individual susceptible to secondary infections, which prevention measures should also aim to mitigate.
Therefore, secondary prevention occurs at the stage where the disease onset has already happened and early treatment is used to cure or stop the progression of the disease, thereby lowering its impact on the host's health.

cell structure varies depending on its what?
Answer:
The correct answer is function.
Explanation:
The structure of a particular cellular constituent has a lot to do with its activity. It can also be said that structure dictates function. Let us consider an example of chloroplast and mitochondria, it is only the compositions of these two organelles that permits the procedures of photosynthesis and cellular respiration to take place.
In both the organelles, the existence of the membrane permits for compartments to develop. These compartments can exhibit distinct hydrogen ions concentration, and it is because of these differences in concentration the formation of essential substances takes place.
Which inheritance pattern results when parents are crossed for pure traits and the resulting offspring have traits that appear to blend?
incomplete dominance
codominance
Mendelian inheritance
polygenic inheritance
The right answer is incomplete dominance
Incomplete dominance is when hybrids of the F1 generation have an intermediate phenotype (between the two phenotypes) compared to the parental P1 generation. This phenomenon occurs in heterozygous individuals.
Example: The color of snapdragon flowers.
The pink color obtained in the F1 generation is incomplete dominance. These flowers are heterozygous. When we cross the flowers obtained in the F1 generation to obtain the F2 generation, we obtain a ratio of genotypes and phenotypes that is the same or 1: 2: 1.

As electrons are passed through the electron transport chain associated with photosynthesis, they lose energy. what happens to this energy?
a.it is used to phosphorylate nad+ to nadph, the molecule that accepts electrons from photosystem i.
b.it is lost as heat,
c.it is used to establish and maintain a proton gradient.
d.it excites electrons of the reaction center of photosystem i.
Low-energy electrons destroy oxygen molecules and produce water as they move through the electron transport chain, losing energy as they do so. Thus, option C is correct.
What proton gradient cause in electron transport chain?The electron transport chain in particular utilizes the energy from the electrons on NADH and FADH2 to pump protons (H+) into the intermembrane gap.
As a result, there is a proton gradient between the mitochondria's matrix and intermembrane space.
Hydrogen is pumped out of the matrix space by the energy released. As a result, a gradient is produced that forces hydrogen back through the membrane via ATP synthase.
Therefore, electron transport chain associated with photosynthesis, they lose energy because it is used to establish and maintain a proton gradient.

What is the central dogma of biology identify and describe the molecular processes that accomplisht he flow of genetic information described in the central dogma?
Final answer:
The central dogma of biology outlines the flow of genetic information from DNA to mRNA to protein, primarily through the processes of transcription and translation. Transcription makes an RNA copy of a gene, and translation uses that RNA to build a protein.
Explanation:
Central Dogma of Molecular Biology
The central dogma of molecular biology describes the flow of genetic information in cells from DNA to RNA to protein. The genetic information is first transcribed into messenger RNA (mRNA) during transcription, and then the mRNA is translated into a protein during translation.
Transcription
Transcription is the process by which a segment of DNA is copied into mRNA. This occurs when the cell needs a particular protein, and the gene responsible for that protein is activated. As the DNA is transcribed, nucleotides are matched to synthesize the single-stranded mRNA molecule.
Translation
Translation is the process whereby the sequence of the mRNA is used to dictate the correct order of amino acids that make up the protein. This involves reading the mRNA nucleotides in groups of three, known as codons, with each codon corresponding to one specific amino acid. Thus, a protein's structure is determinate by the nucleotide sequence of the gene.
(05.01 MC) How do wetlands abiotically help to protect the water quality of a marine ecosystem? They cause areas to flood into larger water bodies. They cause the water to be filled with tannins. They filter sediments and other material from runoff. They prevent water from being stored in their areas.
Answer:
They filter sediments and other material from runoff
Explanation:
Wetlands are places that are mostly ‘wet’ most of the time of the season and are filled with aquatic plants and riparian vegetation. Most of the time this water is still and anoxic. Wetlands are important because they allow the sediments in the still waters to settle, and also the ecosystem takes out the nutrients/dissolved molecules hence purifying the water before it is released into the water bodies such as oceans and lakes.

In one family, all three children are homozygous for a recessive gene. What can be concluded about the parents?
Both parents are likely homozygous recessive as well for the gene in question, as each child inherits one allele from each parent and all children are homozygous for a recessive gene.
If all three children in a family are homozygous for a recessive gene, it can be concluded that both parents are at least carriers of the recessive allele. Given that each child has inherited two recessive alleles (one from each parent), both parents must possess at least one recessive allele each to pass on to their offspring. Since all the children are homozygous recessive, this suggests that both parents are likely homozygous recessive as well for that particular gene.
Jenna made this model to show the processes which resulted in the formation of oceans.
Which of these statements best describes a flaw in Jenna's model?
Water filled the basins after sea floor spreading.
Water filled the basins after segments of Earth's crust moved.
Earth's crust was formed after water filled the basins.
Earth's crusts were broken down after the process of sea floor spreading.
The answer is Earth's crust was formed after water filled the basins.
There is a flaw in this statement because the earth’s crust is the top-most layer of the earth that occurs across the whole of the earth. Actually, the reverse happens, the oceans sit on top earth’s crust therefore cannot be formed after water filled the basins.
