Answer:
When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts.

approximately how much dna is found inside the nucleus of a typical human cell if it were unwound and stretched end to end
Answer:
2 meters (3 Gb of base pairs)
Explanation:
The human genome is composed of 3 billion (3 Gb) base pairs, which are organized in 23 pairs of chromosomes. Within the nucleus, DNA is compacted by histone proteins to form nucleosomes and these structures are then organized in chromatin fibers that undergone higher-order compaction. The compaction of chromatin fibers is accomplished by proteins and Matrix attachment DNA regions (MARs) that bind specifically to the nuclear matrix. In an unwound state, each cell nucleus in the human body has approximately 2 meters of DNA (if the DNA molecule would be stretched end-to-end).

A plasmid that encodes resistance to ampicillin and tetracycline is digested with the restriction enzyme PstI, which cuts the plasmid at a single site in the ampicillin-resistance gene. The DNA is then annealed with a PstI digest of human DNA, ligated, and used to transform E. coli cells. What antibiotic-resistance phenotype(s) (characteristics) will be found on the plate
Answer: Tetracycline.
Explanation:
A plasmid is a small circular DNA molecule found in bacteria that is separate from the bacterial chromosome and replicates independently of it. They encode for certain genes that play a key role in antibiotic resistance. Restriction enzymes are endonucleases that catalyze the cleavage of phosphodiester bonds in different regions located within a DNA strand. PstI is an example of an endonuclease, it is a type II restriction enzyme produced by the microorganism Providencia stuartii that possesses a restriction target in double-stranded DNA dependent on an unmethylated, palindromic, asymmetric sequence, and in this example, it cuts the plasmid at a single site in the ampicillin-resistance gene. After that, the DNA is annealed with another fragment of DNA and this new recombinant molecule is used to transform E. coli cells. Transformation is a key step in DNA cloning because it occurs after restriction enzyme digestion and ligation treatments and transfers newly made plasmids into bacteria. So these bacterias will have a new fragment of DNA, which still has a tetracycline resistance gene but it no longer has the ampicillin resistance gene because it was disrupted by the restiction enzyme. Thereby, the antibiotic resistance phenotype is the tetracycline resistace.

In an energy pyramid, which level has the most available energy?
A.Producer level
B.First level consumer
C.Second level consumer
D.Third level consumer
Answer:
The correct answer is -A. producer level.
Explanation:
the first trophic level is the level of photosynthetic organisms they produce their food and energy on their own from the ultimate source of energy, the Sun. This is why they are called producers.
Producers have the most energy in any ecological ecosystem as all other organisms get food from these directly or indirectly. Only 10 percent of total energy is transferred from one trophic level from producers to the next tropic level through consumers of different trophic levels.

what are all the steps of the water cycle
Answer:
Brainliest please!
1. Evaporation - During this process, surface water turns into water vapor. This is done by the transfer of heat energy. Water absorbs this heat energy and turns into its gaseous state.
2. Condensation - Water vapor rises into the atmosphere and is changed into water droplets. When gas is chilled, it turns back into a solid state. These water particles that form in the atmosphere then come together to form clouds.
3. Sublimation - Ice directly converts into water vapor without first converting into a liquid. This process accelerates when the temperature is low or pressure is high.
4. Precipitation - It is the result of evaporation and condensation. Precipitation describes any liquid or solid water that falls to Earth as a result of those two processes. It includes rain, hail, snow, sleet and a bunch more.
5. Transpiration - When precipitation happens, the soil absorbs some of the water. While in the soil, the roots of plants will take in the water and push it towards the leaves where it is used for photosynthesis.
6. Run Off - This happens as a result of precipitation, so it is again, technically not a process. As water pours down, it leads to runoff. This is the action of water running over the surface of the Earth. As water runs over the ground, it can displace the topsoil with it and move minerals along lakes, seas and oceans.
7. Infiltration - This last process happens when water does none of the things stated above after precipitation. Sometimes, some of the water will move deep into the soil. Avoid the plants, avoid evaporation, avoid runoff, everything. The water instead seeps down and increased the level of the groundwater table. It is called pure water and is 100% fresh and drinkable.

A few years ago, the labels from one class section's experimental treatments plants fell off in the greenhouse and got swept away! One group was the only group in the section to test the effects of indole acetic acid (IAA) on bean plants. The IAA group applied lanolin paste to one side of their bean stems. What should they look for in order to identify their experimental plants from other groups
Answer:
The group needs to find signs of apical dominance, growth in response to light, vascular tissue differentiation, formation of lateral and adventitious roots, etc.
Explanation:
Lanolin is a solvent used to study physiological processes in plants by diluting hormone growth regulators (in this case, indole acetic acid). Indole acetic acid (IAA) is the most important auxin hormone in plants. Auxins are essential plant hormones synthesized in expanding shoot tips that move down the stem to the roots. These hormones coordinate cell division, elongation and identity during plant body development. IAA hormone is well known to regulate different plant developmental processes including, among others, apical dominance (where the central stem grows more strongly than other lateral stems), tissue differentiation, stem elongation, phototropism (growth in response to light) and gravitropism (response to gravity). For instance, under the application of IAA, it is expected that bean stems grow to imitate the response to light (phototropism) by bending away from the side where lanolin was applied.
An old alternative hypothesis for the evolution of infanticide was that parents killed offspring (including their own) when food was short for the good of the group. On the basis of a modern view of adaptation, why is this not a good explanation for the evolution of infanticide
Answer:
On the basis of gender preference.
Explanation:
In the modern view of adaptation, the main cause of infanticide is not the food but the gender preference. In many societies, people killed their infant when they knew that the infant is a girl. They thought that having a girl is curse or shameful thing so they kill the infant. These type of people wants male baby or prefer male child so that's why they kill the infants. In the ancient times, infants were killed that were abnormal or having any defects but today it happen due to gender preference.

Answer:
B
Explanation:
But instead of it being RNA it would be DNA->mRNA->protein
The correct order of steps in gene expression is DNA to RNA to protein, The correct option is B.
What is gene expression?The process by which the information stored in a gene is used to create a functional product, such as a protein, is referred to as gene expression. This procedure is divided into two stages: transcription and translation.
From DNA to RNA to protein, This is known as molecular biology's central dogma and describes the flow of genetic information within a biological system.
Through a process known as transcription, DNA serves as a template for the synthesis of RNA. In turn, RNA serves as a template for protein synthesis via a process known as translation.
Thus, the correct option is B.
