Explanation:
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.

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.
what are the four primary uses or benefits of the nguni breed amongst South African communities?
Answer:
Utility: The Nguni cattle are used for milk and meat; their socio-cultural functions are also important. The body conformation of the Nguni is more of a dairy than beef type but it is principally used for beef production and for work.
Explanation:
How has the human population grown in the last 200 years? Why has human population growth accelerated in the last 200 years?
Answer:
1. The size and growth rate of the human population has changed in the past 200 years because reproduction rates have increased due to the large number of people in the world. 2. Human population has grown exponentially over the past century. It has done so largely by producing large amounts of food, and learning how to control disease. Ten thousand years ago, when humans first invented agriculture, there were maybe one million humans on the planet.

Which organism in the food web below is likely to store the most energy?
boa constrictor
beetle
coati
poison dart frog
sloth
strangler fig
fungus
fruit bat
A. Strangler fig
B. Boa constrictor
C. Beetle
D. Poison dart frog
Answer:
Beatle
Explanation:
Beetle in the food web below is likely to store the most energy. So, the correct option is (C).
What is Food Web?A food web is defined as the natural interconnection of food chains and is a graphical representation of what-eats in an ecological community. Food web is also known as consumer-resource system.
A food web consists of many food chains while a food chain follows only one path as animals find food. For example, Falcon eats snake, which has eaten frog, which has eaten grasshopper, which has eaten grass. Thi shows the many different pathways that plants and animals are connected.
In this, the lower trophic level organisms have more energy than the upper trophic level because only 10% of the energy flows from one trophic level to the next. In the above case, beetles have the highest energy compared to other organisms.
Thus, Beetle in the food web below is likely to store the most energy. So, the correct option is (C).

Which organism, roadrunner or the owl, competes more for its food?
Support your answer with evidence from the food web.
The roadrunner and the owl are both predators and compete for similar prey, such as small mammals, birds, reptiles, and insects. However, the extent to which they compete for food depends on various factors such as their habitat, size, behavior, and hunting techniques.
What do you mean by predators ?
Predators are animals that hunt, kill, and consume other animals (known as prey) for their sustenance. Predation is a common form of interaction between different species in many ecosystems. Predators come in many different forms, such as mammals, birds, fish, insects, and reptiles.
Predators are typically characterized by certain physical and behavioral adaptations that help them hunt and capture prey. For example, many predators have sharp teeth, claws, or beaks that are used to kill and consume their prey. Others may have specialized hunting techniques or strategies that make them highly effective predators.
The roadrunner and the owl are both predators and compete for similar prey, such as small mammals, birds, reptiles, and insects. However, the extent to which they compete for food depends on various factors such as their habitat, size, behavior, and hunting techniques.
Roadrunners are known to be opportunistic hunters and can feed on a wide range of prey items. They are ground-dwelling birds and use their speed and agility to catch their prey. Roadrunners are also known to eat eggs and young of other birds, including owls.
Owls, on the other hand, are nocturnal predators that are known for their exceptional hearing and vision, which enables them to hunt in low light conditions. They are also skilled hunters and can catch a variety of prey, including rodents, small mammals, and birds.
Therefore, both roadrunners and owls are capable of competing for food, but the level of competition depends on the availability of prey, habitat, and other factors. In general, the competition between these two species is likely to be limited, as roadrunners are diurnal (active during the day) and owls are nocturnal (active at night).

what is the smallest unit of DNA molecule that can be altered by a mutation and cause a change to the coding of polypeptide
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.
