Many scientists say that there is a good reason for gaps in the fossil record. Can you explain why some extinct animals and plants were never fossilized?
Answer:
For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying. When an organism is buried quickly, there is less decay and the better the chance for it to be preserved.

A person touches a hot object and immediately moves her finger away from it. Which of the following structures is the first to receive an impulse triggered by the stimulus? and why
A Synapse
B Ventral root ganglion C Motor neuron
D Sensory neuron
E None of the above
The Sensory neuron is the structure that first receives an impulse triggered by the stimulus. Thus, the correct option is D.
What are Sensory neurons?Sensory neurons may be characterized as nerve cells that are activated by sensory input or external stimulus from the environment.
When a person touches a hot object and immediately moves her finger away from it. This is because sensory neurons are activated by an external stimulus, which is sent to the central nervous system of the body, and a motor response is sent out to the skeletal muscles that regulate this movement.
Therefore, the correct option for this question is D.

The genetic code is redundant, with more than one codon for some amino acids, and nearly universal—the genetic code is shared by organisms from the simplest bacteria to the most complex plants and animals.
The genetic code is a set of rules that dictates how the sequence of nucleotides in DNA and RNA is translated into the sequence of amino acids in proteins. One of the essential features of the genetic code is its redundancy. There are 20 different amino acids used in protein synthesis, but there are 64 possible codons (combinations of three nucleotides) in the genetic code.
The genetic code is nearly universal. This means that the same codons code for the same amino acids across different organisms, from bacteria to plants to animals. This universality of the genetic code is a strong indication of the common ancestry of all living organisms on Earth. Despite the vast diversity of life, the fundamental genetic code remains highly conserved and shared among all organisms.

What happens to species diversity WITHOUT Pisaster? *
Answer:
The starfish Pisaster ochraceus is a keystone species in the rocky marine intertidal communities off the northwest coast of North America. This predatory starfish feeds on the mussel Mytilus californianus and is responsible for maintaining much of the local diversity of species within certain communities. A keystone species is an organism that helps define an entire ecosystem. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche.

name and describe the process occurring in the nucleus wich results in the formation of an mRNA molecule.
Answer:
The correct answer is - transcription.
Explanation:
Transcription is the process that takes place in the nucleus and the final result of the process is an mRNA molecule that encodes the information of a specific DNA sequence.
Transcription in prokaryotes is carried out in three stages.
Initiation: Here, RNA polymerase binds to the promoter region and transiently binds to the ‘initiation factor’ to initiate transcription.
Elongation: This is the step where the RNA strand starts getting longer. RNA polymerase “walks” along one strand of DNA. For every nucleotide recognized on the DNA template, it adds a complementary RNA nucleotide to the growing RNA transcript.
Termination: Transcription stops once the RNA polymerase reaches the terminator region. At this region, the RNA transcript and the RNA polymerase, both fall off. RNA polymerase transiently associates with the ‘termination factor’ to stop transcription.
What is Nuclear Transplantation?
Answer: Nuclear transfer is a form of cloning. The steps involve removing the DNA from an oocyte, and injecting the nucleus which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining in a pluripotent state.Nuclear transfer is a form of cloning.

based on the information on the map where are the most stable ecosystems usually found?
The correct answer is C. Near the equator.
Explanation
The image shows a world map in which there is a horizontal black line in the middle that represents the equator line and some red areas. These areas are the most stable ecosystems in the world since due to their proximity to the equator the incidence of the sun's rays is more direct. Also, in these areas, there is no weather pattern defined by seasons, but climates are defined by altitude, that is, meters above sea level. Therefore, the correct answer is C. Near the equator.

The following Punnett Square is a monohybrid cross. It takes the genotypes of the parents and predicts the genotypes of their offspring. Fill in the punnett square. Each square will have 2 letters
Answer:
For the 1st block on the left I think there are 2 dominants for that would be BB. The 1st block on the right would be 1 dominant and 1 recessive and that would be Bb. The bottom on the left would be the same as the first block on the right. That would be Bb. The last block that would be the bottom right would be 2 recessives and that would be bb. I hope this might help.
Explanation:
When you are doing punnet squares, you have dominant and recessive traits. There are ways you can do that. If you have 2 alleles of each parent of that offspring, there will be a genotype and a phenotype that represents a genetic trait of each genotype. I hope this helps your question.

2. Which agricultural specialist is most likely to perform research to understand factors impacting the pH of soil?
A. Entomologist
O B. Animal scientist
C. Plant pathologist
D. Agronomist
Answer:
D. Agronomist
Explanation:
Agronomists are professionals that study how to make soils more productive (in terms of food) around the world. Soil pH is an index that calculates the acidity/alkalinity of the soil, which is indicated on a 14-point scale (pH equal to 7 = neutral; pH below 7 = acidic, pH higher than 7 = alkaline). In this regard, it is well known that the pH of the soils drastically affects plant development, and thereby a proper soil pH is fundamental to ensure optimal plant growth (required for nutrient intake). For this purpose, agronomists are in charge of studying and researching the pH of the soils in order to increase crop yields. Nowadays, the pH of the soils can be easily measured by digital soil pH pocket testers that utilize a pH electrode in order to calculate the pH value.

If a physician orders that a patient be given 4 grams of a medication that it is only available in 1000
milligram tablets, how many tablets should the natient hominen?
Answer:
4 tablets
Explanation:
Based on the information in this question, a doctor/physician orders that a patient be given 4 grams of a medication. However, the medication is only available in 1000 milligram (mg) tablets.
Since 1000mg = 1g
This means that one of the available tablet is 1g.
Hence, in order to give exactly 4grams of a 1g tablet, 4/1 = 4 tablets must be given to the patient.

what is the process when an embryo embeds itself into the endometrium
Answer:
Implantation is a process in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth. The lining of the uterus (endometrium) prepares for the developing blastocyst to attach to it via many internal changes.
Explanation:
☁️ Answer ☁️
Implantation
1. Implantation is the process where the embryo attaches to the uterine lining (endometrium) and embeds itself into the tissue. This happens around Day 5 or so of the embryo’s development.
