which of the following statements is true?rosalind franklin was awarded the nobel prize in 1962.oswald avery did not have evidence that dna is the molecule of heredity. with the exception of identical twins, each person has a unique dna sequence.dna is organized in a straight ladder design
Answers
The statement that is true among the options provided is: "With the exception of identical twins, each person has a unique DNA sequence."
Each person's DNA contains a unique sequence of nucleotides that make up their genetic code.
This uniqueness arises from the combination of genetic information inherited from both parents during the process of sexual reproduction. While siblings share certain genetic similarities, their DNA sequences are distinct from each other. The exception to this is identical twins, who develop from a single fertilized egg and thus have identical DNA sequences.
Regarding the other statements:
Rosalind Franklin was a pioneering scientist who made significant contributions to the discovery of the structure of DNA, but she was not awarded the Nobel Prize. The Nobel Prize in Physiology or Medicine in 1962 was awarded to James Watson, Francis Crick, and Maurice Wilkins for their discoveries related to the structure of DNA.
Oswald Avery, along with his colleagues, provided evidence that DNA is the molecule of heredity through their experiments on the transforming principle in bacteria.
DNA is not organized in a straight ladder design. It has a double helix structure, resembling a twisted ladder, with the two strands held together by hydrogen bonds between complementary nucleotides.

Answers
The diagram of the plasma membrane of your organism’s cell is shown in the image attached.
What is diffusion across the plasma membrane?
The movement of molecules or ions across the phospholipid bilayer that makes up the plasma membrane of a cell, from an area of higher concentration to an area of lower concentration, is referred to as diffusion over the plasma membrane. It is a passive process that doesn't need energy to be added.
Because the plasma membrane is selectively permeable, only some chemicals can pass through while others are prevented from doing so. When substances, like gases (oxygen and carbon dioxide) or tiny, uncharged molecules (water, ethanol), move through the plasma membrane along a concentration gradient, this is known as diffusion.

how does the calvin cycle function?drag the terms on the left to the appropriate blanks on the right to complete the sentences. not all terms will be used.
Answers
The Calvin cycle is a process that occurs in the stroma of chloroplasts and is responsible for fixing carbon dioxide into organic compounds.
The cycle begins with the enzyme RuBisCO catalyzing the attachment of \(CO_{2}\) to a 5-carbon sugar called RuBP, which forms a 6-carbon intermediate that quickly breaks down into two 3-carbon molecules called PGA.
ATP and NADPH from the light-dependent reactions are used to reduce PGA into \(G_{3}P\), which can be used to synthesize glucose or other organic molecules.
One \(G_{3}P\) molecule is exported out of the chloroplast to be used by the cell, while the rest of the G3P molecules are recycled back into RuBP using additional ATP.
The cycle is then ready to begin again with the attachment of another molecule of \(CO_{2}\) to RuBP.

In drosophila,dna replication in bacteria versus drosophila that could explain this is Eukaryotic chromosomes have many origins of replication, while bacteria have only one origin of replication.
In comparison to unicellular creatures, multicellular organisms have far more stable settings where nutrients are less likely to be scarce. These cells' size, meanwhile, still has a significant impact on how they behave. Blood cells, for instance, must retain a tiny enough size to fit through capillaries, and neurons must travel long distances to transmit impulses down the lengths of limbs.

mast cell stabilizers and leukotriene inhibitors are used prophylactically to control inflammation in asthma.
T/F
Answers
True. Mast cell stabilizers and leukotriene inhibitors are indeed used prophylactically to control inflammation in asthma.
Mast cell stabilizers, such as cromolyn sodium and nedocromil, work by preventing the release of histamine and other inflammatory mediators from mast cells, thereby reducing the likelihood of an asthmatic response. These medications are usually inhaled and help prevent asthma symptoms by reducing inflammation in the airways. Leukotriene inhibitors, such as montelukast and zafirlukast, block the action of leukotrienes, which are chemical substances that contribute to inflammation, bronchoconstriction, and mucus production in asthma. By inhibiting leukotrienes, these medications help prevent and reduce the severity of asthma attacks.
Both mast cell stabilizers and leukotriene inhibitors are considered preventive medications, meaning they are used to reduce the frequency and severity of asthma symptoms rather than for immediate relief during an asthma attack. They are often used in conjunction with other asthma medications, such as bronchodilators and corticosteroids, to provide optimal asthma control.

The descriptions below explain two ways that water is used by plants on a sunny day.
I. In a process called transpiration, some liquid water in leaves changes to water vapor. The water vapor is released into the air through tiny pores in the leaves. This allows more liquid water from the soil to be pulled up the roots and stem to replace water lost from the leaves.
II. Plants use some of this water in leaves in a process called photosynthesis. During photosynthesis, water and carbon dioxide break apart and recombine to form two new substances, oxygen, and glucose.
Based on the above description of transpiration and photosynthesis, which type of change happens to water during each process?
A. In transpiration, because some of its properties change, water undergoes a physical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a chemical change.
B. In transpiration, because some of its properties change, water undergoes a chemical change but keeps its identity. In photosynthesis, because its identity changes, water undergoes a physical change.
C. In transpiration, because its physical properties change, water undergoes a physical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a chemical change.
D. In transpiration, because its chemical properties change, water undergoes a chemical change and loses its identity. In photosynthesis, because it keeps its identity, water undergoes a physical change.

A.. Compare and contrast the morphology of the ghost crab and a typical trilobite in terms of their main body parts. Consult available references and see the Appendix (p. A-14) to compare their appendages. How are these organisms similar? How are they different? Similarities: Differences: B. The hole in the sand into which the ghost crab disappears is the entrance to a burrow made by the crab as a dwelling place ("domichnion"). The burrow is surprisingly long (up to a meter) and has a side branch leading to the surface. Why would the crab go to the extra work of making two entry ways?
Answers
A. Morphology of ghost crab and a typical trilobite in terms of their body parts:
Ghost crab is a crustacean and possesses a hard exoskeleton that provides protection against predators. It has five pairs of legs. Its body is divided into two segments: the cephalothorax and the abdomen. The cephalothorax is covered by a carapace that protects the gills and internal organs. The eyes of the ghost crab are located on stalks that allow the crab to have a 360-degree vision.
A trilobite is an extinct arthropod that lived during the Paleozoic era. It has three parts: the head (cephalon), the thorax, and the pygidium. The cephalon was the most developed part of the trilobite and had a pair of compound eyes and antennae. The thorax was composed of a series of segments, each of which had a pair of legs. The pygidium was composed of a series of segments and served as the tail. The trilobite had an exoskeleton that was divided into three parts: the dorsal part, the ventral part, and the pleural part.
In terms of appendages, both ghost crab and trilobite have jointed appendages.
However, there are some differences. The appendages of the ghost crab are specialized for walking and digging. The first two pairs of legs are pincers that are used for capturing prey. The last three pairs of legs are used for walking and burrowing. The appendages of the trilobite are more varied and are specialized for different functions. Some appendages were used for swimming, some for crawling, and some for capturing prey.
Similarities: Both ghost crab and trilobite are arthropods. They have jointed appendages and a hard exoskeleton that provides protection against predators. Both have an anterior cephalothorax and a posterior abdomen.Differences: The body plan of ghost crab is bilateral, while that of trilobite is radial. Ghost crab is a living organism, while trilobite is extinct. Ghost crab has five pairs of legs, while the number of legs in trilobites varied. Trilobite has a more complex morphology with specialized appendages.
B. The reason why the ghost crab goes to the extra work of making two entryways: The crab makes two entryways to its burrow to improve ventilation and prevent the accumulation of toxic gases. The side branch allows fresh air to enter the burrow, while the main entrance allows the crab to exit quickly if it senses danger. The side branch also helps the crab to dispose of waste material. The burrow also serves as a protection against predators and harsh environmental conditions. The burrow provides a stable temperature and humidity that is necessary for the survival of the crab. The long burrow allows the crab to move deep into the sand where it can stay moist and avoid desiccation.

1. Hair grows about __________________ millimeters each day- or about ____ centimeter per month. Why?
Answers
Answer:
Explanation:
Hair grows about 0.3 to 0.5 millimeters each day, or about 1 centimeter per month on average. The rate of hair growth can vary slightly depending on factors such as age, gender, genetics, and overall health.
Hair growth occurs in three stages: anagen, catagen, and telogen. The anagen phase is the active growth phase, during which new hair cells are produced and hair grows. This phase can last anywhere from 2 to 7 years, depending on the individual. The catagen phase is a transitional phase that lasts for about 2 weeks, during which hair growth slows down and the hair follicle starts to shrink. The telogen phase is the resting phase, during which hair growth stops and the old hair falls out. This phase lasts for about 3 to 4 months before the cycle starts again.
Based on this hair growth cycle, the average hair growth rate of about 1 centimeter per month can be calculated. However, it's important to note that individual hair growth rates can vary based on the factors mentioned above.

bla
Answers
Answer:
Explanation:
To calculate how much more blood flows per minute to the skeletal muscles during intense exercise than during rest, we need to use the following formula:
exercising - resting = increased blood flow
Substituting the given values, we get:
exercising - resting = increased blood flow
exercising - 1,200 cm³/minute = 4.CC
To solve for exercising, we need to isolate the variable on one side of the equation. Adding 1,200 cm³/minute to both sides, we get:
exercising - 1,200 cm³/minute + 1,200 cm³/minute = 4.CC + 1,200 cm³/minute
exercising = 4.CC + 1,200 cm³/minute
Therefore, the equation to calculate how much more blood flows per minute to the skeletal muscles during intense exercise than during rest is:
exercising = 4.CC + 1,200 cm³/minute
