Which critter trait is affected by an environmental factor, such as light, temperature, or
diet? Explain.
Answer:
Tallness.
Explanation:
Tallness is the critter trait that is affected by an environmental factor, such as light, temperature, or diet because the organism remains short if they are not getting food properly as well as temperature. Food provides essential nutrients that contribute in the growth of organism. Suitable temperature of the body allows the different functions in the body to be done which directly affects the growth of the body and the organism becomes taller.

Calculate the number of neutrons in atoms of the isotope 3919K
With working out
Answer:
20 neutrons
Explanation:
In the atom of an element, there exists three subatomic particles namely; proton, neutron and electron etc. The sum of the number of neutrons and number of protons (a.k.a atomic number) in an atom makes up the mass number.
In this question, an element was given as follows: 39- 19 K meaning that the mass number is 39 but the atomic number is 19.
Hence,
no of. neutrons = mass no. - atomic no.
39 - 19 = 20 neutrons.
The islets of Langerhans are surrounded by
A-exocrine cells that produce digestive fluid.
B-endocrine cells that produce digestive fluid.
C- exocrine cells that produce glycogen
D-B and C
PLEASE HELP ME ITS REALLY URGENT CAUSE I HAVE EXAMS TOMORROW!!!
Answer:
A-exocrine cells that produce digestive fluid.
Explanation:
The pancreas is composed of both exocrine cells (capable of producing digestive enzymes) and endocrine cells (involved in the production of hormones that control glucose homeostasis). The islets of Langerhans are clusters or 'islands' of pancreatic endocrine cells, which consist of α-cells that produce glucagon, β-cells that secrete insulin and δ-cells that produce somatostatin. These islets are surrounded by: 1-exocrine cells called 'acini' that produce digestive enzymes such as chymotrypsin, trypsinogen, lipase, and elastase; and 2-bile ductules, which are tubes that carry bile from the liver and the gallbladder through the pancreas.

What is the answer with explaining
Answer:
EeWw
Explanation:
The allele for the earlobe is depicted as e while that of the hairline is w.
A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.
The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww
eeWW x EEww
During meiosis, each genotype will form gametes.
eeWW: eW, eW, eW, eW
EEww: Ew, Ew, Ew, Ew
These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:
eW x Ew
offspring
100% EeWw (see the attached image for the Punnet's square)
The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline.

Explanation:
Why do you think type 2 diabetes occurs so much more often than other inheritable diseases? Propose a hypothesis for why this allele has not been eliminated by natural selection.
Which type of species best describes a mouse: opportunistic or equilibrium? Explain why a mouse or rat population would continuously grow while other mammals (cheetahs) are nearly extinct.
Answer:
This allele has not been eliminated by natural selection because it may confer an adaptive advantage for particular environmental conditions
Mice and rats are opportunistic species. These species can rapidly adapt to different environmental conditions, while cheetahs are unable to adapt to changing environments.
Explanation:
An allele is a gene variant that may be beneficial, neutral, or deleterious for a particular environment. Different alleles are not eliminated by natural selection against other alleles (even when a priori seem to be deleterious) because they confer a selective advantage in a given environment. For example, the allele for sickle cell anemia is caused by a point mutation which is lethal in homo-zygous individuals, but heterozygous individuals are less likely to die of malaria, thereby this allele has been positively selected in geographic areas where malaria is an endemic disease. Moreover, mice and rats are opportunistic species, i.e., they are species that rapidly adapt to varied living conditions. These species are characterized to have high growth rates and produce many offspring. On the other hand, the cheetah is a highly specialized species that is unable to adapt to changing environments. In consequence, cheetah populations are more prone to become extinct than rat and mice populations.
What is the probability that a hybrid individual with the genotype AabbCcddEeFf will produce a gamete that has the genotype abCdeF
Answer:
6.25%
Explanation:
Find the number of different gametes that can be produced
number of gametes produced = 2^n
n is the number of allele pairs that are heterozygous
there are 4 heterozygous allele pairs, these are: Aa, Cc, Ee and Ff
2^4 = 16
abCdeF is one of the 16 genotypes that could be produced
to find the percentage, divide 1 and 16 and multiply by 100
1 ÷ 16 = 0.0625
0.0625 × 100 = 6.25
Quadrupedal monkeys __________ Group of answer choices have long arched spines for flexible movement when leaping. hold their bodies parallel to the ground (pronograde posture) when walking have narrow rib cages with scapula on the side, limiting the range of motion in the shoulder All of these traits characterize quadrupedal monkeys
Answer:
All of these traits characterize quadrupedal monkeys
Explanation:
Quadrupedal monkeys have long arched spines that is used for flexible movement when jumping to a height. They hold their bodies parallel to the ground because of pronograde nature means these monkeys walking with the body by using four legs. While walking they have narrow rib cages with scapula on the side that limits the range of motion in the shoulder.

Discuss who is impacted by desertification including which continents are impacted and the role of an increasing population.
Answer:
Africa and Asia.
Explanation:
Africa and Asia are the most affected regions in the world which is greatly affected by desertification. The climate change and human activities has a great impact in these areas which causes desertification as compared to other areas in the world. The increase in population increase the rate of depletion of natural resources which causes more pollution in the environment that leads to desertification in these areas.
When you pushed the diaphragm up what change occurred in chest cavity pressure? Explain how this change in chest cavity pressure affected the lungs.
Answer:
positive pressure
Explanation:
Exhalation is a passive process during which the intercostal muscles and the diaphragm relax. The ribs move downward and inward, while the diaphragm rises. This movement causes the chest to decrease in size and positive pressure to build inside the chest cavity. The positive pressure pushes air out of the lungs.

It was found that the C4 protein promotes synaptic pruning during brain development in the teenage years. This is a normal process in brain development that is important for removing unnecessary connections between neurons and establishing a mature brain structure. However, high expression levels of a certain allele of C4 can lead to too much pruning, which may promote the onset of schizophrenia. The variation observed at the C4 gene which leads to the greatest increase in risk was found to cause a 25% increase in the risk of developing schizophrenia. The baseline risk in the population is 1%. What is the risk of an individual with this variant developing the condition?a. 0.25%.
b. 1.25%.
c. 25%.
d. 26%.
Answer:
b. 1.25%
Explanation:
Variations observed in C gene has increase in risk of 25% to develop schizophrenia. It is a kind of an abnormality in which a person interprets reality unrepresentative. The baseline risk in population is 1% then there is 1.25% risk associated with an individual to develop this condition.

Assignment 1 - Provide a narrative for the following scenarios. Use complete
sentences and be careful with spelling and grammar. 20 Points (5 points each)
1. The physician orders urine C&S on a patient. The patient asks why it is
necessary to do this test. How would you, the medical assistant, clearly
explain this to the patient?
2. A patient is asked to bring in a first morning urine specimen for testing.
You, the medical assistant, provide the patient with a container for the
collection and explain that it needs to be refrigerated if they cannot bring
it to the office right away. How do you explain to the patient the need
for a first morning specimen and the request to refrigerate?
3. A patient is being treated for diabetes. This patient asks you, the
medical assistant, why it is necessary a urine specimen is collected each
Answer:
1.Urine culture and sensitive is used to identify the microorganism that is causing the infection, and to identify the antibiotics, sensitive to the microorganism, if the urinary tract is not treated promptly it can lead to recurrent urinary tract infection.
2. First urine sample of the morning is more concentrated form as urine is present in the bladder for almost 8 hours. It contains an increased number of protein or urinary casts. The sample is placed in the refrigerator to get refrigerated as holding it at room temperature and if infected with bacteria present in the urine it uses the glucose and alter the results.
3. diabetic ketoacidosis is one of the many complications if you are having diabetes. Another complication is diabetic nephropathy inorder to check the urine acetone as well as protein in urine we advise for urinalysis each time you visit.

what are the qualities of woollen fabric that makes it suitable for winter
Answer:
Heat conductivity
Explanation:When wool fibres are exposed to heat, moisture, and strain, they interlock and contract. Felting is aided by the scale-like exterior of the fibres. Heat conductivity: Since wool fibre is a weak conductor of heat, fabrics made from it are best suited for winter wear
If the complex cholesterol- HRP would not be commercially available, use the knowledge you learnt and internet to determine an alternative way for detecting cholesterol.
Answer:
Classical chemical methods, enzymatic assays, gas chromatography (GC), liquid chromatography (LC), and mass spectrometry (MS)
Explanation:
Classical chemical methods, enzymatic assays, gas chromatography (GC), liquid chromatography (LC), and mass spectrometry (MS) are the alternate methods used for the detection of cholesterol. These methods are used when HRP would not be commercially available for the analysis or detection of cholesterol in the patient's body so these methods can be used for the purpose of detection of cholesterol.
