Answer:
1. Within
2. Among two different
Explanation:
There is more genetic variation WITHIN a population than AMONG TWO DIFFERENT populations. This is evident in the fact that phenotypic variation occurs at a greater length within a population resulting from natural selection based on survival and the ability to produce offspring strategy. This unlike populations that consist of two or more different populations mingled together.

What is the difference between Mutualism, Commensalism, and Parasitism?
Answer:
Mutualism: Both Benefit
Commensalism: One benefits but the other party is not harmed
Parasitism: One party is harmed while the other benefits.
Explanation:
Answer:
say big dripSo, to review, mutualism is where both organisms benefit, commensalism is where one benefits and the other is unaffected, and parasitism is where one benefits and the other is harmed.Mutualism is the interaction between two or more organisms where both organisms can benefit from the interaction. An example of mutualism is a Clownfish and a Sea Anemone. ... Parasitism is the interaction between two species where only one benefits from the other organism and the other is harmed in return.

A biology student wanted to determine if there is a relationship between resting heart rate and time spent exercising per week.He gathered information from 12 classmates and constructed the graph below.What is likely to be a resting heart rate for a student who exercises about 3 hours a week ?
A-69bpm
B-62bpm
C-81bpm
D-75
Answer:69bpm
Explanation:i just did it
From the graph, the likely resting heart rate for a student who exercises about 3 hours a week would be 69 bpm.
What is resting heart rate?It is the normal rate at which the heart pumps blood when in resting conditions.
From the graph, the resting heart rate is inversely proportional to the number of hours spent exercising per week.
For someone that exercises 3 hours per week, the resting heart rate hovers between 70 and 65 bpm.
Thus, the likely resting heart rate from the available option would be 69 bpm.

Explanation:
What would happen if the members of one homologous pair did not segregate to opposite poles, but instead both went to the same pole
Answer:
Daughter cells with abnormal number of chromosomes will be produced (aneuploidy)
Explanation:
Ideally, homologous pair of chromosomes are meant to separate into opposite poles during the anaphase I stage of meiosis. However, a failure to separate, a process called MEIOTIC NON-DISJUNCTION, will cause some daughter cells to have more than the required/normal chromosome number while some daughter cells will have less than the normal or no chromosome.
This abnormality in chromosome number caused by failure of chromosome to separate is called ANEUPLOIDY. In a nutshell, when this occurs, the daughter cells will possess abnormalities in chromosome number i.e trisomy, monosomy etc.

Arnoldo is a botanist studying inheritance in flowers. When he crosses pure breeding red carnations with pure breeding white carnations, the offspring in the F1 generation have pink flowers. In the F2 generation, some
flowers are red, some flowers are white, and some flowers are pink When he crosses blue poppies with yellow poppies, all the offspring in the Fgeneration have both blue and yellow petals In the F2 generation, some
have only blue petals, some have only yellow petals and some have both yellow and blue petals
Which of the following correctly identifies the inheritance patterns Arnoldo is observing?
Flower color in the poppies is polygenic, while flower color in the carnations is controlled by multiple alleles
Answer:
A is the answer
Explanation:
The statement that correctly identifies the inheritance patterns is the yellow allele is incompletely dominant over the blue allele in the poppies, while the red and white alleles in the carnations are codominant. The correct option is D.
What is inheritance?Genetic information is transmitted from parent to kid through inheritance. Members of the same family typically share traits in common because of this.
As it relates to genetics, the term "inherited" describes a feature or variation that is encoded in DNA and passed from parent to child during reproduction. The laws of Mendelian genetics govern inheritance.
Therefore, the correct option is D. The yellow allele is incompletely dominant over the blue allele in the poppies, while the red and white alleles in the carnations are codominant.

many plants can reproduce by vegetative reproduction. what is the main benefit of this form of reproduction?
Answer: Some plants can produce seeds without fertilization via apomixis where the ovule or ovary gives rise to new seeds. Advantages of asexual reproduction include an increased rate of maturity and a sturdier adult plant.
How can an organism maximize their kcal intake and minimize their energy output?
Answer:
arbohydrates, protein, fats, and alcohol—the dietary macrocomponents—are the sources of energy in the diet. Under normal circumstances, more than 95% of this food energy is digested and absorbed from the gastrointestinal tract to provide the body's energy needs. Studies of normal and overweight subjects have not shown any significant differences in the proportion of food energy absorbed. In some underweight subjects, however, malabsorption of nutrients is an important factor. Food energy is used to meet the body's needs, including protein synthesis; maintenance of body temperature, cardiac output, respiration, and muscle function; and storage and metabolism of food sources of energy. When more energy is consumed than is needed for metabolism and physical activity, the excess is stored, primarily as adipose tissue.

Some plants have leaves that are poisonous to some animals. Which kind of adaptation is this? (1 point)
Survival
reproduction
respiration
defense
Answer:
this is for defence
Explanation:
Defense is mechanism of adaptation by which some plants have leaves that are poisonous to some animals.
Poisonous plants are those herbs, flowers, shrubs or fruits that are toxic enough to harm the body of people as well as dogs, cats and other animals.
The defense mechanisms that plants have developed are very varied and among them are physical adaptations such as thorns or the synthesis of chemical substances that can inhibit consumption by predators and some with antimicrobial effects.
During the evolutionary process, all organisms have been attacked by viruses, bacteria and fungi; likewise, they are consumed as a source of nutrients by different herbivorous animals and vertebrates.
In response to external factors that limit the normal development of plants, they have developed various defense mechanisms ranging from anatomical adaptations to chemical defense.
The chemical substances produced by plants as defense, are very varied, have different functions, inhibit the action of pathogens and prevent their attack, others cause negative effects at different levels, such as irritation on contact, nausea or gastric disorders.
Some of these compounds are saponins, phenolic compounds that include phenolic acids, and complex polymers such as tannins and lignin have the ability to cause pharmacological and toxicological effects in animals.
Therefore, we can conclude that plants have developed various defense mechanisms as chemical defense by which some plants have leaves that are poisonous to some animals.
