Graduate students monitoring the benthic organisms of a freshwater lake take samples at different depths throughout the lake and identify the invertebrate species present. In a deep region of the lake, they discover a crustacean that appears to be a new species. They decide to study its natural history. What is the first thing they should do in this study?
Answer:
Do a literature search to find natural history information on closely related species.
Explanation:
In the context, few graduate students monitored the benthic organisms from the fresh lake water samples and identified the invertebrate species that are present.
They also discover a crustacean which appears to be the new species for which they decided to do a study on its natural history. The first thing that the graduate student should do is to do a literature search for finding a natural history on the information that are closely related species.

Investiga un uso beneficioso (medicina o industrial) para las bacterias, virus y Hongos microscópicos. Explica brevemente su utilización.
Answer:
- Hongos: antibiótico penicilina
- Bacterias: producción de insulina para uso humano
- Virus: vectores basados en adenovirus para el desarrollo de vacunas
Explanation:
Los microorganismos son fundamentales para el desarrollo de diferentes tipos de aplicaciones industriales y medicinales. Por ejemplo, la penicilina es una sustancia sintetizada por el hongo Penicillium notatum, la cual es ampliamente utilizada como antibiótico debido a sus propiedades antibacterianas. Las penicilinas son antibióticos del grupo de los betalactámicos que tienen como núcleo un anillo central de beta-lactama, las cuales son capaces de destruir una amplia variedad de bacterias. Por otra parte, las bacterias pueden ser usadas para la generación de moléculas orgánicas con fines médicos. Por ejemplo, cepas de Escherichia coli han sido modificadas mediante técnicas de ingeniería genética con el objetivo de producir insulina humana, una hormona central en el metabolismo de la glucosa. Mediante técnicas de recombinación genética, el gen responsable por sintetizar insulina humana ha sido introducido en bacterias. Las cepas de E. coli son relativamente fáciles de cultivar en el laboratorio y por lo tanto permiten obtener grandes cantidades de esta hormona (insulina). Finalmente, existen ciertas tipos de virus inocuos para nuestro organismo los cuales han sido recientemente utilizados como vectores para el desarrollo vacunas. Mediante esta técnica de ingeniería genética, un determinado vector viral (por ejemplo, un virus de la familia de los adenovirus) es modificado genéticamente con el objetivo de insertar un fragmento de un agente infeccioso o 'antígeno' el cual individualmente es incapaz de producir daño. Las vacunas diseñadas a partir de vectores virales son inofensivas para el organismo pero son capaces de desencadenar una respuesta inmune contra el antígeno recombinante, generando de este modo una memoria inmunitaria en contra el agente infeccioso.

Which student provides the best explanation of how to determine whether Cell A or Cell B is a plant or animal cell? Rusty- "cell A is an animal cell because it contains more organelles than a plant cell, Cell B" Kristin- "Cell A is a plant call because it has large vacuole in the middle of the cell to provide support, structure, and storage for the cell" Darryl- " Cell B is an animal cell because it has nucleus" Eleanor- " Cell B is a plant cell because is has a larger cytoplasm then cell A which stores a plants water and minerals."
Answer:
Kristin's answer is the best.
Explanation:
It is the only correct answer.
The student that best explains whether Cell A or Cell B is a plant or animal cell is Kristin who said that "Cell A is a plant call because it has large vacuole in the middle of the cell to provide support, structure, and storage for the cell".
Distinctive features of plant and animal cellsCell is the structural and functional unit of the living organism which contains organelles that carry out specific functions.
The plant cells can be distinguished from an animal cell through the following features:
it possess a larger vacuole which is centrally placed and helps in the storage of cell wastes.It possess cellulose cell wall that provides support and structure to the cell.They also possess chloroplasts which are not seen on animals cells.Therefore, the student that best explains whether Cell A or Cell B is a plant or animal cell is Kristin who said that "Cell A is a plant call because it has large vacuole in the middle of the cell to provide support, structure, and storage for the cell".

Proteins secreted by Gram-negative cells face multiple obstacles, including _____. Multiple choice question. moving across the periplasmic space underlying the thick peptidoglycan layer of the cell wall moving across the plasma membrane moving across the plasma membrane and the thick peptidoglycan layer of the cell wall moving across both the plasma membrane and the outer membrane
Answer:
moving across both the plasma membrane and the outer membrane
Explanation:
Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.

Answer:
well for one you can find a lot for examples like if the light of a blazing hot sun was reflecting on a wooden stick the spot where the sun is reflecting would have a red mark with smoke comming out the stop
this part too #stresscrying
Explanation:
It could be that both the parents were heterozygous, meaning having a dominant and recessive allele for example Aa..after these are paired you would see that they will form a white fur offspring.

Express this sense sequence as a polypeptide. Use the three letter abbreviation and separate the amino acids with a dash - e.g. Trp-Thr-Ala. If there is a stop codon - you may add an asterisk to the sequence - e.g. Trp-Thr-Ala-* ATTTTAGCCATGCCCGGGAAAATACGCCGCCCTCCCGGTACACCATTGTTCGGCAAATAAAAATAAAAT polypeptide sequence [answer1] what is the DNA sequence of the 5' UTR? [answer2] what is the RNA sequence of the 3' UTR [answer3]
Answer:
- Protein sequence: Met-Pro-Gly-Lys-Ile-Arg-Arg-Pro-Pro-Gly-Thr-Pro-Leu-Phe-Gly-Lys-*
- DNA 5' UTR: ATTTTAGCC
- RNA 3' UTR: UAAAAAUAAAAU
Explanation:
Transcription is the process in which a DNA sequence (e.g., a gene) is used as template (transcribed) in order to synthesize an RNA molecule, usually a messenger RNA molecule, which is then used as template to produce a polypeptide sequence (protein) in the ribosomes. In RNA, Thymine (T) bases are always replaced by Uracil (U) bases. An mRNA strand is formed in the 5′ to 3′ direction. Each triplet of nucleotides is referred to as a codon and the resulting mRNA strand is translated starting from codon AUG (Methionine), while there are three different stop codons or 'or termination codons' in the genetic code that terminate translation: UAG, UAA, and UGA.
Compare photosynthesis and cellular respiration. In what types of cells do these processes occur?
Answer:
Cellular respiration occurs in both plants and animals.
But photosynthesis occurs only in plants. But photosynthesis can happen to 4 animals. It is only an exception, however. Sea slug and pea aphid may perform photosynthesis, oriental hornet, spotted salamander.
Explanation:
ATP is the main energy source of the cell. The most important final product of cellular respiration.The two main final photosynthesis products are glucose and oxygen.
Some of the cellular respiration enzyme reactions occur in the cytoplasm but the bulk is in the mitochondria. Inside the chloroplast, photosynthesis occurs.NADH is the high-energy cellular respiration electron carrier, while NADPH is photosynthesized as a powerful electron carrier.In the cell chloroplasts, photosynthesis is carried out. This process gives energy directly or indirectly to all living organisms. Life on Earth would be no longer there without it.
Although photosynthesis needs energy and produces food, cellular breathing breaks food down and releases energy. Photosynthesis and respiration are carried out by plants while animals can only breathe.
Those who argue that objectivity is impossible are known as activitists.
