Which statement explains the difference between a nerve that is connected to the skin and a nerve that is connected to a muscle? The nerve that is connected to skin is a motor neuron; the nerve that is connected to a muscle is a sensory neuron. The nerve that is connected to skin receives stimuli information from the external environment; the nerve that is connected to a muscle receives processed stimuli information from the brain. The nerve that is connected to skin is part of the central nervous system; the nerve that is connected to a muscle is part of the peripheral nervous system. The nerve that is connected to skin helps the body maintain homeostasis; the nerve that is connected to a muscle supports the body so it can stand upright.
Answers
The nerves connected to the skin are usually sensor neurons, more precisely their endings which react to heat and cold, touch, pressure, vibration or tissue injury. The nerves connected with muscles are motor efferent nerves which are responsible for sending out commands from the CNS to the body and thus, stimulating muscle contraction.

Darwin hypothesized that there are definite steps to natural selection. Consider the model of bacterial resistance to antibiotics. How would Darwin explain step I?
Question 1 options:
Bacteria adapt to environmental changes.
Some bacteria alter their DNA in response to environmental changes.
In any population, some individuals are weaker than others.
In any population, genetic variation exists.
Answers
Two main types of bacteria on the basis of colur have shown in figure. Red type bacteria are more resisrtant than orange type bacteria. According to Darwin theory of natural selection, resistant bacteria are more favoured by nature because they can survive and not affected by drugs. As a result they will survive while orange will finish with the passage of time. Now reb bacteria as they survive will produce offspring and increase their population because the are survival of the fittest.
What is likely phenotypic ratio resulting from a dihybrid cross with alleles showing epistatic interactions?
Answers
The answer is one (1) phenotype. This is because epistasis interaction of gene alleles involves the masking of one phenotype of an allele of a gene (at one or more loci) by the other. Alternatively, the epistatic alleles may interact to cause a modification of a phenotype.
Final answer:
The phenotypic ratio from a dihybrid cross which includes epistatic interactions differs from the non-epistatic 9:3:3:1 ratio, with the actual ratio depending on the specific nature of the epistatic relationship between the genes involved. One gene may mask the effects of another, altering the expected ratios of phenotypes in the offspring.
Explanation:
The phenotypic ratio resulting from a dihybrid cross with alleles that show epistatic interactions will differ from the classic 9:3:3:1 ratio seen in Mendel's dihybrid crosses with non-interacting genes. This is because epistasis is a form of gene interaction where one gene masks or modifies the expression of another. For example, if one gene's expression is completely dependent on another gene, you might see a modified ratio such as 9:3:4, where the 4 represents the epistatic effect.
In a case of epistasis similar to the one described by the figure, where one gene (C) masks the expression of another (A) for a trait like coat color, the presence of the C allele is necessary for color to be expressed. If it's absent (cc), no color is expressed regardless of the A gene's alleles. Here, the phenotypic ratio can deviate significantly from the typical 9:3:3:1 observed in a dihybrid cross without epistasis. The actual ratio will depend on the specific epistatic relationship between the genes involved.
It's important to remember that the independent assortment of genes and Mendelian inheritance can be altered by various genetic interactions, including epistasis, which must be taken into account when predicting phenotypic ratios in genetics problems.
Termites are insects that chew on wood. Based on a termites diet, which of the following statements would you expect to be true about its digestive system?
a.) The termite's digestive tract produces fast-acting meat-digesting enzymes.
b.) The termite has flattened molars that grind wood.
c.) The termite has a jaw bone and muscles that are adapted for side-to-side grinding movements.
d.) The termite has a symbiotic relationship with cellulose-digesting microorganisms in its digestive tract
Answers
Answer: d.) The termite has a symbiotic relationship with cellulose-digesting microorganisms in its digestive tract.
Explanation:
Termites are the wood eating parasites. They eat wood to meet their nutritional demands. Although there are enzymes present inside the termites which can partially digest the cellulose. But they exhibit a symbiotic relationship with the bacteria present in their gut. The bacteria helps in digestion of rest of the cellulose. In return the bacteria receives shelter and food.

Answers
Mutualism
Mutualism is a relationship between organisms of two different species in which each benefits. From the question given above, the relationship between the termites and the unicellular organism can be described as mutualism because both organisms benefit from each other.
The relationship between the termites and the unicellular organisms in their intestines is an example of mutualism, a type of symbiotic relationship where both organisms benefit. The protists help digest cellulose from the termite's wood diet, providing nourishment for both organisms.
Explanation:The relationship between the termites and the unicellular organisms in their intestines is an example of mutualism. In this symbiotic relationship, both organisms benefit. The unicellular organism known as protists, which survives in the termite's gut, assist the termites in breaking down the ingested cellulose from their wood-based diet into a digestible form that provides nourishment for both the termite and the protists.
This process represents a mutualistic relation because while the protists are obtaining a safe habitat and a constant supply of food from the termite, they are also essential in processing cellulose from the wood, aiding the termite in deriving essential nutrients. Without this digestive assistance by the protists, the termite cannot obtain energy from its food.
Furthermore, the protists themselves are able to digest cellulose due to the presence of symbiotic bacteria within their cells that produce the cellulase enzyme. This results in a complex mutualistic interaction where both the termite and the protists (and the bacteria within the protists) derive strategic survival advantages from each other.

According to the hardy-weinberg principle, if 75% of the alleles in the gene pool are a1 and 25% are a2, what is the proportion of individuals with genotype a1a2 in this population?
Answers
Frequency of allele a2 is 25%, q=0.25
If a population is in Hardy-Weinberg equilibrium then:
p2+2pq+q2=1
p2 is the frequency of genotype a1a1 (homozygous),
2pq is the frequency of genotype a1a2 (heterozygous),
q2 is the frequency of genotype a2a2
The proportion of individuals with genotype a1a2 is then 2*0.75*0.25=0.375 (37.5%).
According to the Hardy-Weinberg principle, the proportion of individuals with genotype a1a2 in a population can be calculated using the formula 2pq, where p is the frequency of allele a1 and q is the frequency of allele a2.
Explanation:According to the Hardy-Weinberg principle, the proportion of individuals with genotype a1a2 can be calculated using the formula 2pq, where p is the frequency of allele a1 and q is the frequency of allele a2. In this case, the frequency of a1 is 0.75 and the frequency of a2 is 0.25. Therefore, the proportion of individuals with genotype a1a2 is 2(0.75)(0.25) = 0.375, or 37.5%.

When plants make "food" by photosynthesis, they change the energy in sunlight to?
Answers

Pray this helps you. :)
Plants change sunlight into chemical energy through photosynthesis, creating glucose and oxygen from water and carbon dioxide.
When plants make "food" through photosynthesis, they change the energy in sunlight into chemical energy. This fascinating process involves plants taking solar energy and using it to combine water (H₂O) and carbon dioxide (CO₂) to create glucose (C₆H₁₂O₆), which is a carbohydrate, and oxygen (O₂). The light energy harnessed from the sun is transformed into chemical potential energy stored in the glucose molecules. Autotrophs, like plants, capture a specific wavelength of sunlight through chlorophyll and use it during photosynthesis to build these carbohydrate molecules. The glucose produced can then be used by the plant for its growth and development or stored for later use, supporting the energy needs of the plant itself and herbivores that consume the plant matter.

Answers
Fungi are heterotrophic organisms which feed by absorption. Their structures hyphae secrete digestive enzymes, which break down the substrate. Their nutrition is parasitic (obtaining food from the host) or saprobic (feeding on dead organic remains).
Animals use holozoic nutrition meaning that they eat their food whole. They processed the food via a special digestive system and this consists of 5 stages, ingestion, digestion, absorption, assimilation and egestion.
