6.what type of survivorship curve would you expect for a plant species in which only a few seeds are produced and most of these survive to produce adult plants?
Answers
A plant species that produces few seeds with high survival rates would exhibit a Type I survivorship curve.
A Type I survivorship curve is typically observed in species with high survival rates during early and middle life stages, followed by a sharp decline in survivorship as individuals reach old age. This pattern is commonly associated with species that exhibit parental care and invest significant resources in the survival and well-being of their offspring.
In the case of the plant species you described, where only a few seeds are produced but most of them survive to become adult plants, it suggests that the species has mechanisms in place to ensure the survival and growth of its offspring. This could include factors such as protective seed coverings, nutrient-rich seed reserves, or specific adaptations that enhance seed germination and early growth.
The high survival rate of the seeds leading to the development of adult plants indicates successful reproduction and efficient utilization of resources. This suggests that the species has evolved strategies to maximize the survival and growth of its offspring, resulting in a Type I survivorship curve.
Overall, a Type I survivorship curve in this plant species reflects a life history strategy that prioritizes the survival and successful reproduction of a relatively small number of offspring.

The question is in the file.
Answers
Answer:
Frequency of dominant allele is 0.9029
Explanation:
Total number of organisms = 12,845
Number of organisms representing dominant trait = 11,596. These organisms might have heterozygotes with one dominant allele and one recessive allele.
Hence, Number of organisms with recessive alleles = 12845 – 11596 = 1249
Frequency of recessive allele (q) = 1249/12845 = 0.0971
Frequency of dominant allele (p) = 1- q = 1- 0.0971 = 0.9029

Jason notices that his shower is covered in a strange green slime. His friend FeFe tells him that coconut juice will get rid of the green slime. Jason decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.
Answers
Answer:
This question is incomplete, the question is asking to identify the following aspects of the experiment:
Dependent variable: Amount/appearance of green slime
Independent variable: Coconut juice
Constant: Same shower
Control group: half of the shower sprayed with water
Experimental group: half of the shower sprayed with coconut juice
Explanation:
The independent variable in an experiment is the variable that is changed or manipulated in order to bring about an effect. In this case, the independent variable is the COCONUT JUICE.
Dependent variable is the variable being measured by the experimenter in an experiment. In this case, the dependent variable is the AMOUNT/APPEARANCE OF GREEN SLIME.
Experimental group is the group that received the experimental treatment in an experiment. In this case, the experimental group is the HALF PART OF THE SHOWER SPRAYED WITH COCONUT JUICE.
Control group is the group that does not receive the experimental treatment in an experiment. In this case, the control group is the HALF PART OF THE SHOWER SPRAYED WITH WATER.
Constants in an experiment are those variables that are kept the same for all groups in an experiment. In this case, a constant is the SAME SHOWER USED THROUGHOUT.

e. studies of similarity in sex orientation of identical twins could not be replicated
f. neurodevelopmental traits g. initial evidence focused mostly on gay men h. maternal immunization to sex-specific proteins
Answers
According to Mills, the genetic basis of same-sex orientation and sexual behavior has remained undiscovered by researchers due to the influence of each of the following except d. prenatal exposure to sex hormones and h. maternal immunization to sex-specific proteins.
Mills argues that there is a lack of conclusive evidence linking genetics to same-sex orientation and behavior due to several factors. One of the factors is the use of small and non-representative cohorts in studies, which limits the generalizability of the findings. Another factor is that the speculative evidence of a relationship with fraternal birth order is not backed by strong empirical evidence. Furthermore, twin and family studies showed no correlation, and studies of similarity in sex orientation of identical twins could not be replicated, this lack of replication suggests that there may be other environmental and non-genetic factors at play.
Lastly, Mills argues that neurodevelopmental traits may contribute to same-sex orientation, but their relationship to genetics is not yet well understood. In summary, while prenatal exposure to sex hormones and maternal immunization to sex-specific proteins have been ruled out as reasons why the genetic basis of same-sex orientation has remained undiscovered, other factors such as small sample sizes and inconclusive evidence still hinder progress in this field. So the correct answer is d. prenatal exposure to sex hormones and h. maternal immunization to sex-specific proteins.

if you cross two heterozygous yy pea plants, what fraction of the offspring will be heterozygous? chegg
Answers
If you cross two heterozygous yy pea plants, all of the offspring will be heterozygous.
In this scenario, the genotype of the two parent pea plants is yy, and they are heterozygous. The lowercase "y" represents the recessive allele for a specific trait. When two heterozygous individuals are crossed, each parent can pass on either the dominant or recessive allele to their offspring. Since both parents have only the recessive allele (yy), they can only pass on the recessive allele to their offspring.
As a result, all of the offspring from this cross will inherit one recessive allele (y) from each parent, making them heterozygous (Yy). The heterozygous genotype indicates that the offspring have one dominant allele (Y) and one recessive allele (y) for the particular trait.
It's important to note that this outcome assumes that the trait being considered follows a simple Mendelian inheritance pattern, where the dominant allele masks the expression of the recessive allele. Additionally, this answer assumes that there are no other factors, such as genetic linkage or interactions with other genes, influencing the inheritance of the trait in question.

Answers
The 1980 eruption of Mount St. Helens was a violent explosion that ejected a large amount of ash and rock debris, while a typical eruption of Hawaii's Kilauea Volcano is a non-explosive outpouring of fluid lava from the volcano's vent.
The 1980 eruption of Mount St. Helens was a highly explosive event that released a massive amount of energy and caused widespread destruction in the surrounding area. The eruption involved a vertical blast that ejected a large amount of ash and rock debris, as well as a lateral blast that triggered a devastating landslide. In contrast, a typical eruption of Hawaii's Kilauea Volcano is a relatively quiet event that involves the outpouring of fluid lava from the volcano's vent. These eruptions are not typically associated with explosions or the ejection of large amounts of debris.
The Hawaiian Volcano Observatory has been operating near Kilauea's summit for over 100 years because the volcano erupts frequently and provides an opportunity to study volcanic processes over a long period of time. In contrast, Mount St. Helens does not erupt frequently and was not as well monitored before the 1980 eruption. Overall, the eruptions of Mount St. Helens and Kilauea are very different in terms of their explosiveness, frequency, and associated hazards.

Answers
a. Children inherit two copies of each chromosome. c. Genes are segments of DNA located on chromosomes that code for traits. d. One chromosome comes from the mom and one from the dad.
The presence or absence of dimples is a trait that is influenced by genetic inheritance. To explain the situation where you have dimples while your siblings do not, the following factors apply:
a. Children inherit two copies of each chromosome: Each person receives one copy of each chromosome from their mother and one copy from their father. This includes the chromosomes carrying the genes responsible for dimples. Differences in the genetic information received from your parents can account for the presence of dimples in you but not in your siblings.
c. Genes are segments of DNA located on chromosomes that code for traits: Genes are the units of inheritance, and they are located on chromosomes. Variations in the specific genes related to dimples can explain why you have them while your siblings do not.
d. One chromosome comes from the mom and one from the dad: In sexual reproduction, you inherit one chromosome carrying the genes related to dimples from your mother and one from your father. Differences in the combination of genes received from each parent can result in variations in traits between siblings.
Option e is not applicable in this context since traits like dimples are generally inherited and influenced by genetic factors rather than being random mutations.
Overall, the combination of inheriting two copies of each chromosome, the presence of genes on those chromosomes that code for traits like dimples, and the variation in genetic information received from each parent can explain why you have dimples while your siblings do not.

A red bloom cell has diameter of 0.008mm. a model of the red blood cell has a diameter of 80mm. What is the scale of the model
Answers
Scale of the model: 1:10,000. To find the scale of the model, we need to compare the size of the model to the actual size of the red blood cell. Given that the diameter of the red blood cell is 0.008mm and the diameter of the model is 80mm, we can calculate the scale by dividing the diameter of the model by the diameter of the actual cell.
Scale = Model diameter / Actual cell diameter
Substituting the given values:
Scale = 80mm / 0.008mm
Simplifying the expression:
Scale = 10,000
Therefore, the scale of the model is 1:10,000.
1. Identify the diameter of the red blood cell: 0.008mm.
2. Identify the diameter of the model: 80mm.
3. Use the formula Scale = Model diameter / Actual cell diameter.
4. Substitute the values into the formula: Scale = 80mm / 0.008mm.
5. Simplify the expression to find the scale: Scale = 10,000.
6. The scale of the model is 1:10,000, indicating that the model is 10,000 times larger than the actual red blood cell.
