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.

A chemist weighed out 101. g of beryllium. Calculate the number of moles of beryllium she weighed out.
Answer:
The correct answer is - 11.209 moles.
Explanation:
According to the definition of moles,
moles = weight/molecular weight
given:
weight of beryllium = 101 g
the molecular weight of beryllium = 9.01
∵ 9.01 g weight of beryllium = 1 mole
∴ 1 g weight of beryllium = 1/9.01 moles
∴ 101 g of beryllium =101/9.01 moles
The = 11.209 moles.

Sheila, 32 years old, has been referred to a registered dietitian following her 6-week postpartum check-up following her third pregnancy, as she has concerns about her goals of weight loss and still being able to meet her daughter’s nutritional needs through breastfeeding. This pregnancy was complicated by gestational diabetes, as was her second pregnancy. She gained 37 lbs and states she understands the need to lose her pregnancy weight to reduce the risk of developing type 2 diabetes; she wasn't successful with losing the weight from her second pregnancy. Her daughter was 9 pounds 11 ounces at birth and has been gaining weight appropriately. Sheila breastfed her first two children until they were approximately 5 months old. Her current weight is 223 lbs and her height is 5'5". She reports she hasn't started exercising yet, but she was medically cleared to do so by her physician. Sheila's 24-hour recall shows an estimated calorie intake of 2700 kcal with limited fruits and vegetables, one cup of milk, and portions of high-fat and sugary foods. She has been maintaining her weight with her current calorie intake.

Explanation:
If a diploid eukaryotic cell contains 14 pairs of chromosomes for a total of 2n=28, how many chromosomes will be in the resulting products of cellular division if the cell undergoes:
Mitosis?
Meiosis?
Answer:
Mitosis = 28 chromosomes
Meiosis = 14 chromosomes
Explanation:
- Mitosis is the type of cell division in which the daughter cells are genetically identical to the parent cell and possess the same number of chromosome as the parent cells. For example, a diploid parent will produce a diploid daughter cell after mitosis.
- Meiosis, on the contrary, is the cell division that produces daughter cells that are genetically different from the parent cell. Each daughter cell have a reduced number of chromosomes (by half).
According to this question, a diploid eukaryotic cell contains 14 pairs of chromosomes i.e. 2n=28. After mitosis, each daughter cell will have same 28 chromosomes as the parent cell. Meiosis on the other hand, will produce daughter cells that possess 14 chromosomes each.
Down syndrome in humans is due to ________ of the 21 st chromosome.
Answer:
Down syndrome in humans is due to ADDITIONAL, PARTIAL OR FULL COPY of the 21 st chromosome.
Explanation:
Down syndrome is a genetic disorder in which an individual has a total of 47 chromosomes instead of 46 that is, 23 pairs of chromosomes which is found in normal individuals. This occurs as a result of the presence of additional, partial or full copy of chromosome 21. There are generic variations that occurs in chromosome 21 leading to down syndrome, these include:
-->Trisomy 21 : the individual has three copies of chromosome 21 instead of two copies due to abnormal cell division that occurred during development of sperm or egg.
--> Mosaic Down syndrome: the individual has some cells with an extra copy of chromosome 21 and it's caused by abnormal cell division after fertilization.
--> Translocation down syndrome: This type of down syndrome occurs when chromosome 21 gets attached to another chromosome which occurs during or after conception.
Generally the symptoms due to the presence of this extra genetic material includes:
--> short heights
--> poor muscle development
--> short neck
--> short fingers with small hands and feet
--> increased risk to development of dementia
--> greater tendency to develop obesity

What word means "between the dorsal wall and peritoneum” and refers to the location
of the kidneys?
Answer: The kidneys are situated in between posterior abdominal wall and partial peritoneum.
Explanation:
Kidneys are located at the dorsal side of the body of vertebrates including humans. These are located opposite to the spine. The location of the kidney is the retroperitoneal space that lies in between the posterior abdominal wall and partial peritoneum. Peritoneum is the serous membrane which forms the lining of the abdominal cavity. It also covers the kidneys from the dorsal side. The kidneys are well protected by muscles and fat at the dorsal side.

Explain how competition for food can cause natural selection.
Answer:
Competition for food happens when there is a limited amount of food resources available. The members of a species that eat that food who are best adapted to access the food are more likely to reproduce and pass on their genes to the next generation.
For example, we have a bird feeder with a narrow opening for food. The small-headed birds can reach the food, the bigger-headed birds cannot. If this was the only food source for this area, then over time, there would be more smaller-headed birds than large-headed birds, due to the competition for food and success/lack of success.

D. Energy transferred due to temperature differences
4. An unknown object is placed in contact with a heat
source. It was observed that the object did not increase
its temperature Which of the following explains why?
A. The object is heated too much.
B. The object is heated via radiation.
C. The object is a thermal insulator,
D. The object is a thermal conductor.
Answer:
1. C. Why a handle of a metal spoon also gets hot when placed on a steamy soup.
2. D. It determines the hotness or coldness of an object.
3. D. Energy transferred due to temperature differences.
4. C. The object is a thermal insulator.
Explanation:
Convection is the transfer of heat energy through the movement of a liquid or gas from one place to another. If we place a metal object at a distance from the hot body so the fumes that comes out increase the temperature of the metal that is present on the hot body. Temperature determines the hotness or coldness of an object not the heat. The heat energy transferred from one body to another due to difference in temperature of both objects. Insulator are those materials which no ability to transfer heat energy from one place to another.
1) You can see two moths in this image, Living on the bark of trees. They
are the same species of moth; they differ in color. If the habitat of the
two moths does not change, predict what will happen to the moth
population in this area and explain why.
A)
If the habitat does not change there should be no
change in the moth population.
B)
The lighter moth population will have better chance
of survival due to camouflage. Light moths will
increase: dark moths will decrease.
C)
The population will shift to the to favor the light
moth. The light moth population will increase
because the dark moths will leave the area.
D)
As the seasons change, both moths will be hidden by
foliage growing on the trees. We would predict no
big change in the moth populations, light or dark.
The Correct answer Is B.
this is because of natural selection
hope this helps !
The lighter moth population will have a better chance of survival due to camouflage. Light moths will increase and dark moths will decrease due to industrial melanism. Therefore, option B is correct.
What is industrial melanism?Industrial melanism is a phenomenon in which the frequency of dark-colored or melanistic individuals in a population of organisms increases as a result of environmental pollution.
This phenomenon was first observed in the 19th century in industrialized regions of England, where the population of peppered moths shifted from mostly light-colored to mostly dark-colored in response to pollution from industrial activities.
Thus, the lighter moth population will have a better chance of survival due to camouflage. Light moths will increase and dark moths will decrease. Therefore, option B is correct.

Streptococcus pneumoniae causes all of the following EXCEPT ________. Group of answer choices meningitis. lobar pneumonia. bronchopneumonia. necrotizing fasciitis. bacteremia.
Answer:
The correct answer is ''necrotizing fasciitis.''
Explanation:
Streptococcus pneumoniae belongs to the Streptococcaceae family. It is a Gram positive bacterium, normally facultative anaerobic, catalase negative, immobile, with an oval shape, surrounded by a capsule (does not present Lancefield antigens) and is usually grouped into chains of two (diplococcus) or more bacteria. It can give rise to a wide range of manifestations, among them, the most frequent but the least serious are upper respiratory tract infections, such as: otitis media, sinusitis, etc; while the less frequent but the most serious are: pneumococcal pneumonia, invasive pneumococcal disease, meningitis and septicemia. Necrotizing fasciitis is a rapidly progressive infection that affects the skin, subcutaneous cellular tissue, superficial and deep fascia, causing tissue necrosis and severe systemic toxicity, which, if not treated in a timely manner, is invariably fatal. The most common germs in immunocompetent people are Streptococcus pyogenes and Staphylococcus aureus. In patients with a defined gateway in the skin, the incidence of S. aureus is high. Deep necrotizing processes can be mono- or polymicrobial. In monomicrobial processes, pathogenesis is largely mediated by toxins (FN by S. pyogenes, FN by S. aureus, clostridial myonecrosis). In polymicrobial processes there is a synergism between aerobic and anaerobic germs. The most common aerobes are Enterobacteriaceae, Streptococcus group A, and S. aureus. The predominant anaerobes are Peptostreptococcus spp, Bacteroides fragilis group, Prevotella sp, Porphyromonas spp and Clostridium sp. Streptococcus pneumoniae belongs to the Streptococcaceae family.
