One conclusion drawn from the experiment was that life span differences were independent of reproductive investment. If that is the case, then which of the following statements is true? Females that exhibited catch-up growth and produced many eggs had longer life spans than females that exhibited catch-up growth and produced few eggs. Females that exhibited catch-up growth and produced few eggs had longer life spans than females that exhibited catch-up growth and produced many eggs. Females that exhibited slowed growth and produced many eggs had longer life spans than females that exhibited slowed growth and produced few eggs. Females that exhibited slowed growth and produced few eggs had longer life spans than females that exhibited slowed growth and produced many eggs. Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Answer:
The correct answer is - Females that exhibited slowed growth and produced few eggs had similar life spans to females that exhibited slowed growth and produced many eggs.
Explanation:
According to the question, the life span differences were independent of reproductive investment, on the basis of this experiment, it is clear that the sexual gametes or egg which is a reproductive investment are independent of the lifespan of a female.
The life span of females could be slow growing or not but it will not affect the production of the gametes or eggs. Eggs production is dependent upon hormones produced.

How does variation affect an organism?
Answer:
Explanation:
Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment. An example would be moths of the same species with different color wings.
The genetic code was elucidated through the use of polyribonucleotide's synthesized either enzymatically or chemically in the laboratory. Given what we now know about the genetic code, how would you make a polyribonucleotide that could serve as an mRNA coding predominantly for may Phe residues and a small number of Leu and Ser residues?
What other amino acid(s) would be encoded by this polyribonucleotide, but in smaller amounts?
Answer:
The genetic codes are responsible for coding the amino acids. The messenger RNA (ribonucleic acid) consists of triplet codons, which is responsible for the synthesis of respective amino acid sequences. The UUU codes for the phenylalanine amino acids. Similarly, the incorporation of 5 mixtures such as ADP, GDP, CDP, and UDP can alternatively produce the mRNA polymer with the serine and lysine residue in a small amount.
EXPLANATION:
The genetic codes are responsible for coding the amino acids. The messenger RNA (ribonucleic acid) consists of triplet codons, which is responsible for the synthesis of respective amino acid sequences. The formation of the RNA stand is done by using ADP, GDP, CDP, and UDP (adenosine, guanosine, cytosine, and uridine diphosphate). It requires no template for the formation of polymers. Therefore incorporation of UDP is done by the incorporation of polynucleotide phosphorylase, which will result in the formation of poly U. The UUU codes for the phenylalanine amino acids. Similarly, the incorporation of 5 mixtures such as ADP, GDP, CDP, and UDP can alternatively produce the mRNA polymer with the ser and lysine residue in a small amount. For example in the stretch of polynucleotide UUU presence of one of the following codon UUA, UUG, CUU, CUC, CUA, CUG as well as UCU, UCC, UCA, UCG, and AGU can synthesize leucine and serine residues. (UUC)n can synthesize the polymer of phenylalanine, serine, and incorporation of few A and G will synthesize leucine. However, the presence of A, C, and G can also synthesize a small amount of tyrosine, isoleucine, and cysteine residue.

Answer:
-- individual damaged nucleotides that minimally impact the helix structure.
-- single stranded breaks
Explanation:
The Base excision repair is popularly known as the BER. It is defined as the cellular mechanism which repairs the DNA that are damaged throughout the cell cycle. It helps in correcting the the small base lesions which do not distort the helix structure of the DNA significantly. It is also responsible for fixing the single stranded breaks of the DNA.

Answer:
Hi how are you doing today Jasmine
Answer:
Yes, an animal can adapt into a new species through a process called speciation. Speciation occurs when a population of animals undergoes significant changes over time, leading to the formation of a new species that is different from the original one.
Explanation:
REASONThe main reason for this adaptation and the emergence of a new species is natural selection. Natural selection is the process by which individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Over many generations, these advantageous traits become more common in the population, while individuals without these traits become less common.
When a population of animals faces different environmental conditions or habitats, it can create diverse selection pressures. Some individuals may possess traits that allow them to better adapt to these new conditions, giving them a higher chance of survival and reproduction. As these advantageous traits become more prevalent in the population, they can eventually lead to reproductive isolation.
Reproductive isolation occurs when individuals from the original population can no longer mate and produce fertile offspring with individuals from the newly adapted population. This can happen due to genetic differences and changes that have accumulated over time. When reproductive isolation is complete, the two populations are considered separate species.
SUMMARYOverall, the process of adaptation and the formation of new species is driven by natural selection, which favors traits that enhance an organism's chances of survival and reproduction in specific environments. Over time, these changes can accumulate, leading to the development of distinct species.

©2021 Illuminate Education Inc.
Answer:
hmm
Explanation:
On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
Plausible solution to human activities contributing to increasing amounts of carbon dioxide(carbon emission) in the atmosphere are :
Use only alternative energies for the production of electricityCarbon emission (greenhouse gas emissions) from human activities strengthen the greenhouse effect, causing climate change. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution.
Alternative energy is energy that is collected from renewable resources that are naturally replenished on a human timescale, hence contributing to betterment of environment.To know more about carbon emission here

To survive, an organism must be able to maintain stable internal conditions in a changing environment. This process is called homeostasis. The Human Homeostasis Gizmo™ allows you to explore how the human body stays at a nearly constant temperature in different conditions. Notice the Air temp. and Body temp. thermometers representing the air temperature and body temperature.
1. What is the initial air temperature?
2. What is the initial body temperature?
3. Next to each factor listed below, write "increase," "decrease," or "same" based on how you expect that factor to affect body temperature.
A. Raising air temperature: __same____Sweating: __decrease___.
B. Lowering air temperature: ___increase___Shivering: __increase___.
C. Adding clothing: __increase_____Exercising: ___increase_____.
Answer:
1. Initial air temperature: 0 °C (32 °F)
2. Initial body temperature: 37 °C (99 °F)
3. The expected effect of different factors on body temperature are:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Adding clothing: Increase
D. Exercising: Increase
Explanation:
The question is incomplete, it is necessary to look for a software related to this homework.
Homeostasis is a property of organisms that consists in their capacity to maintain a stable internal condition by compensating for changes in their environment through the regulated exchange of matter and energy with the exterior. It is a a dynamic equilibrium controlled by a mechanism of feedback that constitute the self-regulating mechanisms. Examples of homeostasis are temperature regulation and the balance between acidity and alkalinity (pH)
The Human Homeostasis Gizmo™ is a software that allows you to explore how the human body stays at a nearly constant temperature in different conditions. To use it, you have to set the air temperature at 0 °C (32 °F) and the body temperature at 37 °C (99 °F), and click Play. After a simulation of 1 hour, then click Pause and gather the information. Then, do the same cprocedure to test the effect of other factors and Click Reset between each trial. To determine the effect of different factors on body temperature, you have to compare the final body temperature to the final body temperature while there is no specific movement or change.
Then:
1. Initial air temperature: 0 °C (32 °F)
2. Initial body temperature: 37 °C (99 °F)
3. The expected effect of different factors on body temperature are:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Adding clothing: Increase
D. Exercising: Increase
This is for a logical reason, anything you do to heat it or generate heat, will increase the temperature. And anything you do to generate cold, will lower the temperature.
The effect of different factors on body temperature according to Gizmo:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Click Add to a sweatshirt, hat, pants, and parka. Then, adding clothing:
Maintained
D. Set the Exercise level to 70%, then exercising: Increase
When the temperature increases, it is because you are able to record the results from the software and you see temperature goes from 99 °F to 100 °F. When the temperature decreases. it is because it goes from 99 °F to 97 °F. When it is maintained, there is no change.
