outline how impulses are transmitted from receptor to effector ...?
A receptor is a stimuli receiver. It receives an information and sends it through a sensory neuron to the spinal cord, as a part of the central nervous system. So, the spinal cord sends information received from the body to the brain. Further brain sends the processed information back to the spinal cord which relays it out through a motor neuron to the effectors (muscles or glands).

suppose a population is carrying a condition controlled by two alleles R (dominant) and r (recessive). if the frequency of the r allele is 15% and the frequency of the R allele is 85%. what will be the frequency of the RR genotype ,assuming evolution is not occuring?
Answer:
Frequency of the RR [tex]= 72.25[/tex]%
Explanation:
Given -
R is the dominant allele and r is the recessive allele.
The frequency of the r allele is [tex]15[/tex]%[tex]= 0.15[/tex]
The frequency of the R allele is [tex]85[/tex]%[tex]= 0.85[/tex]
As per Hardy Weinberg's equation-
[tex]p = 0.85[/tex]
[tex]q = 0.15[/tex]
Also, evolution is not occurring is the basic assumption of Hardy Weinberg's principle.
Frequency of the RR genotype is equal to [tex]p^{2}[/tex]
Substituting the value of "p" we get
[tex]p^{2} = 0.85^{2} \\= 0.7225\\= 72.25[/tex]

1. The bodys nonspecific defenses against invading pathogens include ?
A.antibiotics
B.mucus, sweat, and tears
C. antibodies
D. cytotoxic T cells
2. The body's most important nonspecific defense is ?
A. The skin
B. Cell mediated immunity
C. the inflammatory responce
D.permanent immunity
The most important part of the body that shows non-specific defense against invading pathogens is skin (A). They include sweat, acid, mucus, oil in non-specific defense (B).
Further Explanation:
Skin is the major organ of the body, which has several features that shield the body from infections. Skin plays a very important role in nonspecific defense against pathogens. The skin surface receives the secretions from the sweat glands which contains lysozyme. This enzyme is responsible for digesting the bacterial cell wall. This feature alone does not make the skin barrier to infections. The acidic pH and mucus secretion also contribute to the barrier properties of the skin.
The sweat glands and oils are accountable for the acidic pH of 3-5 of the skin surface. This pH is acidic enough to inhibit the growth of pathogenic microorganisms. The skin surface receives the secretions from the sweat glands which contains lysozyme. This enzyme is responsible for digesting the bacterial cell wall. The mucus that is secreted by the skin is a sticky fluid that is responsible for trapping the microorganisms.
The mucus that is secreted by the skin is a sticky fluid that is responsible for trapping the microorganisms. This is one of the few characteristic features of the skin that is responsible for acting as a barrier to infection.

Which of the following best describes the relationship between climate and latitude?
The greater the latitude, the colder the climate.
A latitude of 0o has a climate of extreme temperature ranges.
There is no relationship between latitude and climate.
The lower the latitude, the colder the climate.
Answer:
The best answer choice to the question: Which of the following best describes the relationship between climate and latitude, would be: A: The greater the latitude, the colder the climate.
Explanation:
The explanation is best given not with the understanding of latitudes and climate, but rather, the position of the Earth in regards to the Sun, and its movements, that will bring places further away from the equator (latitude 0), closer to the direct rays of the sun, or further away. However, it is also important to know that as locations move away from the equator, towards higher latitudes, meaning, towards the poles, these places will have lower temperatures, than those on the equator, and definitely will have temperature changes, going from high, to low, depending mostly, on Sun exposure, due to the changes in position of Earth. This also explains why places at greater latitudes experience seasons, and not those at the equator.
you can tell that this is an image of a dna nucleotide and not an rna nucleotide because you see a _____.
You can identify a DNA nucleotide by the presence of a deoxyribose sugar, instead of ribose, and the presence of the base thymine, instead of uracil like in RNA. The key components of a nucleotide are a nitrogenous base, a pentose sugar, and one or more phosphate groups. DNA and RNA differ in the type of pentose sugar and one of the bases they incorporate.
Explanation:You can tell that this is an image of a DNA nucleotide, and not an RNA nucleotide, because you see a deoxyribose sugar instead of ribose. Additionally, you can look to see if there is the base thymine present, which is in DNA, instead of uracil, which is in RNA.
Nucleotides are the building blocks of DNA and RNA. Each nucleotide comprises a nitrogenous base, a pentose sugar, and one or more phosphate groups. The carbon residues in the pentose are numbered 1' through 5' (with the prime distinguishing these residues from those in the base, which are numbered without applying a prime notation). The base is affixed to the 1' position of the ribose, and the phosphate to the 5' position. When a polynucleotide forms, like a DNA or RNA molecule, the 5' phosphate of the incoming nucleotide connects to the 3' hydroxyl group at the end of the growing chain.
The critical difference lies in the pentose sugar included in the nucleotide. DNA contains deoxyribose, which is similar in structure to ribose that is found in RNA. However, deoxyribose has an H instead of an OH at the 2' position.
Moreover, DNA nucleotides incorporate the four bases adenine (A), guanine (G), thymine (T), and cytosine (C). In contrast, RNA uses uracil (U) as a substitute for thymine (T). So, if you see a nucleotide with thymine, that is a direct indicator of DNA. By understanding the core differences between DNA and RNA nucleotides one can easily distinguish between them by examining a given image or model.

2. In Africa, Nile crocodiles can often be seen lying in the sun, their jaws held open. Small white egrets perch on the crocodiles’ backs or hop in and out of their mouths. The birds also peck at the crocodile’s teeth, feeding on the scraps of food embedded there. Although crocodiles do eat some birds, they do not eat egrets.
a. What is the term for the relationship between the crocodiles and the egrets?
b. Explain this relationship.
Answer:
Mutualistic symbiotic relationship
Explanation:
1. The relationship between egrets and the crocodile is a form of symbiotic relationship that is predominantly mutualistic relationship
2. In a mutualistic symbiotic relationship , two species associate with each other in order to benefit each other. Here egrets feed on food scrap stuck in the teeth of crocodile to feed itself while on the other hand crocodile is also benefited as the waste left out of food stuck in its teeth is cleaned off.
Sunlight is a form of energy called _____.
Sunlight is a form of energy known as electromagnetic radiation or solar energy, and the portion that humans can see is termed visible light. It travels in waves, measurable by their wavelength.
Sunlight is a form of energy called electromagnetic radiation or solar energy. This solar energy is composed of tiny packets of energy known as photons. While the Sun radiates a vast amount of this energy, the part that humans can see is called visible light. Solar energy travels in waves, which can be measured in terms of their wavelength - the distance between two consecutive points like crest to crest or trough to trough.
The sun is the Earth's primary source of energy and it emits light and heat through a process called nuclear fusion, where hydrogen is converted into helium, releasing vast quantities of energy. This energy travels across space and reaches Earth mostly in the form of visible light, which we can harness and utilize as an energy resource.
Photosynthetic algae create sugars that will eventually be broken down during which process?
1.glycolysis, during respiration
2.the Calvin cycle, during photosynthesis
3.electron transport chain, during respiration
4.the Krebs cycle, during photosynthesis
The correct answer is:
glycolysis, during respiration
Photosynthetic algae create sugars that eventually be broken down during : A. Glycolysis, during respiration
During this process, Algae produced 2 ATP and 2 NADH, which is used in forming energy.
Explanation:
The cleavage down of sugars is called glycolysis. The prefix glyco- means sugar, and the suffix -lysis means breaking down. It's part of a three-step method in respiration, the other two is The Krebs Cycle and Electron Transport Phosphorylation. In the manner of glycolysis, 2 ATP and 2 NADH are designed. Glycolysis is the metabolic pathway that transforms glucose C₆H₁₂O₆, into pyruvate, CH₃COCOO− + H⁺. The free energy released in this manner is used to form the high-energy molecules ATP and NADH.
what prefix would you add to lysis to mean separate or split using water?
To indicate the splitting or separation of a compound using water, the prefix 'hydro-' is added to 'lysis', forming the word 'hydrolysis'. This chemical reaction is crucial in breaking down polymers into their monomeric units.
The prefix you would add to lysis to mean separate or split using water is hydro-. The complete term is hydrolysis, which is a chemical process where water is used to split a substance into smaller molecules. In the context of polymers, hydrolysis plays an essential role by breaking the covalent bonds between monomers, splitting them into smaller units, often through the addition of a hydrogen ion (H+) to one monomer and a hydroxyl group (OH) to the other, effectively dismantling the polymer chain.
