The DNA codes for traits would not be known.
The protein codes for traits would not be known.
Some alleles are dominant, and some alleles are recessive.
Offspring receive two copies of each allele from each parent.
Answer:
Some alleles are dominant, and some alleles are recessive.
Explanation:
For a recessive allele to generate a recessive phenotype, the individual must exhibit two copies from each parent. An individual with a dominant and one recessive allele for a gene will exhibit the dominant phenotype. A cross between a homozygous recessive and homozygous dominant will always articulate the dominant phenotype, while still exhibiting a heterozygous genotype.
Why do you think it can be difficult for scientists to determine whether an apparent relationship between species is an example of symbiosis? Use evidence from the article to support your answer.
For scientists to determine whether an apparent relationship between species is an example of symbiosis, they must visualize that both are receiving equal shares of benefits.
What would a symbiosis be?The term symbiosis, from the Greek etymons sym (together with) and bios (life), was originally used by the biological sciences to designate a close, harmonious and productive functional relationship between two organisms, which interact actively with a view to mutual benefit.
With this information, we can conclude that for scientists to determine whether an apparent relationship between species is an example of symbiosis, they must visualize that both are receiving equal shares of benefits.

Describe the factors that influence an individuals phenotype
Answer:
Physiology, behavior and morphology are considered as phenotype of an individual as these attributes can be observed. Example of phenotypes include wing length, hair color, skin color and height.
There are basically two factors that influence the phenotype:
(1) Genotype or Genetic information of the individual: Some of the phenotypes such as height and skin color are transmitted genetically from generation to generation. Genetic information is the transfer of genes that carry some of the specific genetic information and pass it to another generation which is visible in their phenotype.
(2) Environmental influence: As the phenotype attributes are variable so they are highly influenced by the environment or surrounding they are living. Environmental condition such as temperature, diet, humidity, oxygen levels, and the presence of mutagens affects the phenotype of an individual.
Hence, Genotype and environmental factors influence an individuals phenotype.

1. A hot liquid or air that expands, becomes less dense, and rises or becomes more dense and sinks.
2. Radiation
3. When you are making soup and the water is rising and lowering.
4. conduction
5. Conduction
6. convection
Explanation:
1. Convection is one of the three methods of heat transfer involving the transfer of heat by the rise and fall of a fluid (liquid and gas) caused by difference in temperature. Based on this, a hot liquid or air that expands, becomes less dense, and rises or becomes more dense and sinks is a perfect definition of convection.
2. Another method of heat transfer called RADIATION involves the transfer of heat between surfaces without a contact between them. The sun heating the human body represents an example of radiation because there is no direct contact between the heat source (sun) and the heated surface (human body).
3. Making soup and the water is rising and lowering is an example of convection because it involves the rising and lowering of a liquid (soup) due to a temperature gradient.
4. Conduction is a method of heat transfer that involves the transfer of heat through a solid medium in direct contact with one another. The solid material is called the CONDUCTOR. The transfer of heat from a warm sand to the bare feet, acting as the conductor is an example of CONDUCTION.
5. Heat is transferred when one touches a fire. This represents CONDUCTION because the fire transfers the heat via a solid medium (hand) in contact with it.
6. The warm air near a room rises because there is transfer of heat, caused by a difference in temperature, through the fluid (gas) causing it to become more dense and rise.

The map shows the main streams and the rivers near City A and City B, as well as the nearby factories and farmland. The arrows in the diagram show the direction of the water flow. City A gets its water from the sunset River and City B gets its water from the Moth Lake. A liquid herbicide was applied to a farmland. Based on the information in the map shown, which city would most likely have the best water quality and why? Choose the best answer.
Select one:
City A because there are no pollution sources upstream.
City B because it is fed by two rivers instead of just one.
City B because it is next to a lake which would have more clean water available.
City A because it is farther North which means it is colder so the water is cleaner.
Answer:
A. City A because there are no pollution sources upstream.
Explanation:
Water pollution is th contamination of water. There are many means through which water is contaminated such as industrial waste, agricultural waste and domestic waste et-cetra.
City A and City B get water from sunset lake and moth lake which have factories (industrial waste) and farmland (agricultural waste) nearby them, which are responsible for the contamination of river water. due to this cities can recieve contaminated water which can affect their health.
But the quality of water in City A will be best than that of City B because according to the image, City A do not have nay upstream soooooource of pollution, as factories and farmland are located at downstream.
Hence, the correct option is A.

ANSWER
we understand ourselves and our motivations. we may not u sweat and others and their motivations as easily.
hope this helps :)
Answer:
Responses may vary but should include some or all of the following information:
The actor-observer bias is a form of attribution bias in which a person is more likely to make an external attribution for behavior when acting and more likely to make an internal attribution for behavior when observing another. The actor-observer bias likely occurs because individuals are more likely to understand the constraints under which they act but are less likely to understand what constrains others.

Explain how traits can be affected by inheritance and the environment?
Final answer:
Traits are influenced by both genetic inheritance and environmental factors, with examples ranging from physical characteristics like height to behavioral aspects such as personality traits. While genetics provide the blueprint, environmental conditions play a crucial role in trait expression, exemplified by the coloration of Himalayan rabbits in different temperatures.
Explanation:
Traits can be influenced by both inheritance and environmental factors. Inheritance is the process through which genetic information is passed down from parents to offspring, which dictates potential traits such as eye color, height, and certain personality tendencies. However, the environment can significantly modify these traits. For example, while height has a genetic basis, factors such as nutrition can profoundly influence the ultimate stature an individual achieves. An illuminating example is the Himalayan rabbit, which develops different fur colors depending on the temperature of its environment; this demonstrates how environmental conditions can affect gene expression and result in different physical outcomes. Behavioral traits also illustrate the interaction between genes and the environment. No specific genes determine behaviors outright, but genetic predispositions can shape behavior which is then further molded by environmental exposure and experiences. For example, while personality disorders may have a genetic component, the likelihood of developing these disorders is also affected by environmental factors such as the presence of child neglect or sexual abuse. Ultimately, recognizing that genes provide the blueprint for potential traits and that the environment can either facilitate or hinder the expression of these traits is essential to understanding human development. This interaction between our genetic makeup and environmental factors contributes to the complexity of traits and is often summarized by the concept of nature through nurture instead of the traditional 'nature versus nurture' debate.

adaptation to avoid predators, while the release of bioactive chemicals by the plant to protect
The green color of a caterpillar often functions as a part of aposematic coloration— a biological adaptation warning predators of toxicity or distastefulness. Examples include the monarch butterfly caterpillar's bright colors and fire-bellied toads' red or orange bellies, both of which serve to deter predators using visual cues.
The green color of the caterpillar is an example of aposematic coloration, which is a type of adaptation used by some species to warn predators of their distastefulness or poisonous nature. This warning coloration involves bright and conspicuous colors that advertise to potential predators the unsuitability of the organism as prey. For instance, the monarch butterfly caterpillar sequesters poisons from its diet of plants and milkweeds, making it poisonous or distasteful. This is visually communicated through its bright yellow and black coloration, which serves as a deterrent to predators.
Similarly, fire-bellied toads have toxins that make them distasteful, and they display bright red or orange colors on their bellies to discourage predators from attacking. This strategy is effective only if the predator uses vision to locate prey and can learn from the negative experience of eating the poisonous or distasteful organism.

Answer: Sam, Tim, Bella, and Joshua
Explanation:
The family members who have red-green color blindness are Sam, Tim, Bella, and Joshua. The correct option is a.
What is color blindness?The only form that truly embodies the phrase "color-blind" is achromatopsia, sometimes known as "total color blindness." Achromatopsia is a condition in which a person can only perceive the world in shades of gray, black, and white.
In pedigrees, the degree to which the form is entirely covered by a certain color—in this case, orange—indicates whether a person exhibits a particular trait.
On the other side, if orange dominates half of the form, the individual is an allele carrier.
A family member's shape is empty if they do not possess or carry the characteristic. Shapes for Sam, Tim, Bella, and Joshua are entirely filled in. They are therefore color-blind to red and green.
