Question Completion:
- a large carbohydrate with partial charges
- a phospholipid
- a nucleic acid carrying
- a negative charge
- a highly polar protein
Answer:
Based on this description, you would guess that the best thing to package the genetic material would be:
- a phospholipid
Explanation:
Since phospholipids work to provide pathways for various substances across cell membranes, they appear to be the best agents or packages for exporting the genetic material of a nucleic acid vaccine. As cell membranes, phospholipids can allow selective passage of some substances into and out of the cells, even though they act as barriers to other molecules and ions.

Without genetic variation, the mechanisms of evolutionary change will not occur. There are several sources of genetic variation
within a breeding population: sexual reproduction, mutation, and gene flow. Specifically, sexual reproduction contributes to
genetic variation and as a result, evolution, through recombination. Describe recombination and analyze how it contributes to
genetic variability. Choose ALL that apply.

When two gametes combine during fertilization to produce children with distinct DNA combinations, this variety is amplified even more, hence a, b, d is the correct option.
What is genetic variation?Crossing over and independent segregation occurs during meiosis I, DNA is exchanged between homologous chromosomes during prophase I when cells cross over.
New allele combinations are produced as a result, chromosomes can arrange themselves in a variety of ways on the metaphase plate, and this process is known as independent segregation.
In metaphase I, this happens, independent segregation but not crossing across occurs during meiosis II.
Therefore meiosis creates variation in the organism which leads to changes during evolution, hence a,b,d is the correct option.

Which of the following is NOT a place that releases enzymes for digestion?
Answer: D. esophagus
Explanation: Because esophagus uses muscles and does not use enzymes to digest. It only transports food to the stomach and then goes further into the digestive system.
Why not your mouth because it uses the enzyme Amylase, which helps break down complex carbohydrates. It is also produced by the mouth. Lipase, which breaks down fats. Protease is a protein-breaking enzyme that breaks down proteins.
Your stomach also uses enzymes as your intestine.

1. Common monosaccharides have a backbone of five or six carbon atoms and two or more
Select
groups.
Between three and eight carbon atoms can be found in a monosaccharide, although only those with five (pentoses) and six (hexoses) are typically seen in nature.
What are the monosaccharides?The most prevalent monosaccharide is glucose, often known as dextrose or blood sugar. However, glucose accounts for a very minor portion of the total carbohydrates in a regular diet.
The majority of the time, glucose is only consumed when it is joined with other sugars to form a poly- or disaccharide.
The three monosaccharides that are most prevalent are glucose, fructose, and galactose. The monosaccharide category also comprises sugar alcohols and pentoses in addition to these three sugars.
Therefore, monosaccharides have a backbone of five or six carbon atoms.

The products of the glycolysis of one molecule of glucose can drive the citric acid cycle
Answer:
Since glycolysis of one glucose molecule generates two acetyl CoA molecules, the reactions in the glycolytic pathway and citric acid cycle produce six CO2 molecules, 10 NADH molecules, and two FADH2 molecules per glucose molecule
The products of glycolysis alone are not sufficient to directly drive the citric acid cycle (also known as the Krebs cycle or the tricarboxylic acid cycle).
However, the output of glycolysis, specifically pyruvate, is a crucial substrate that enters the mitochondria, where it undergoes further processing before entering the citric acid cycle.
The energy carriers, specifically NADH and FADH2, play a crucial role in driving the electron transport chain, the final step of cellular respiration.
The electron transport chain uses the energy from NADH and FADH2 to generate a large amount of ATP through oxidative phosphorylation.
Thus, while the products of glycolysis do not directly drive the citric acid cycle, they contribute to the overall energy production and supply the necessary substrates, such as acetyl-CoA, which is essential for the initiation of the citric acid cycle.

When organic material is completely decomposed, what is left?
Answer:
Its speed is determined by three major factors: soil organisms, the physical environment and the quality of the organic matter (Brussaard, 1994). In the decomposition process, different products are released: carbon dioxide (CO2), energy, water, plant nutrients and resynthesized organic carbon compounds.
Explanation:
After many years of normal function, a cell begins producing different proteins than it produced before. Propose two different explanations for this change.
Answer:
Explanation:
In order to produce different proteins, mutations must occur in the genetic material of the cell. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations: deletion, duplication, inversion, and translocation.
Cells are the functional unit that has a specific activity to perform. The alteration of the cell function can be due to gene or chromosomal mutations.
What are gene and chromosomal mutations?A change in the sequence of the DNA of the gene causes gene mutation and affects the gene or the part of the DNA of the chromosome. They occur in a single place and are called point mutations.
The point mutation is the alteration, addition, deletion or inversion of the single nucleotide base pair of the gene.
The chromosomal mutation affects the whole chromosome and alters the shape and size of the chromosomes. It leads to the increase or the decrease of the ploidy and structural shape.
Chromosomal mutation can be due to translocation, deletion, inversion and duplication of the chromosomes. Their increase or decrease affects the genome as a whole.
Therefore, alteration of the cell can be due to chromosomal or gene mutation.

which of the following structures in a plant cell is responsible for the production of food
Answer:
chloroplastExplanation:
Chloroplasts are specialized organelles found only in plants and some types of algae. These organelles carry out the process of photosynthesis, which turns water, carbon dioxide, and light energy into nutrients from which the plant can obtain energy. There can be over one hundred chloroplasts in certain plant cells.
Chloroplasts are disk-shaped organelles that are surrounded by a double membrane. The outer membrane forms the external surface of the chloroplast and is relatively permeable to small molecules, allowing substances entry into the organelle. The inner membrane lies just beneath the outer membrane and is less permeable to external substances.
Between the outer and inner membrane is a thin intermembrane space that is about 10-20 nanometers wide. The center of the chloroplast that is enclosed by the double membrane is a fluid matrix called the stroma (you can think of this like the cytoplasm of the chloroplast).
Within the stroma, there are many structures called thylakoids, which look like flattened disks. Thylakoids are stacked on top of one another in vascular plants in stacks called grand. Thylakoids have a high concentration of chlorophyll and carotenoids, which are pigments that capture light energy from the sun. The molecule chlorophyll is also what gives plants their green color.
An unusually cold winter causes the squirrel population to decrease. This is an example of temperature as a
A. Carrying capacity
B. Limiting factor
C. Climax community
D. Pattern in space
Please and answer thank you!
Answer:
Most likely B
Explanation:
A - Carrying capacity is the amount of a species that can live in a given area with the given resources, weather does not apply.
B - Limiting factors are things such as food, mates, and competition with other organisms for resources, which can limit the maximum population. Temperature can be applied here, it is the best option.
C - Climax community is when an area's ecosystem is stable, so the term makes no sense used here.
D - To be honest I have no clue what this is. But making an assumption from the term, the winter being "unusually cold" does not make it a "pattern". So I don't think it's this option. I could be wrong, but I assume this is not the right choice.

If a scientist wanted to follow Mendel’s experiment with a different kind of plant, which type of plant would she examine?
Answer: Pure line plant
Explanation:
Pure line plants are those plants that are used for breeding and selecting organisms with a desire trait to a number of generations until the wanted trait is established. Mendel had chosen pea plant for his experiments and that was a pure line species. It was bred to many generations so as to obtain the desired trait in successive generation. The plants were utilized to study the laws of inheritance. Also it was noticed that one trait being recessive in one generation will be expressive in other generation.
