. In a salt marsh in Agusan, the quantity of solar radiation reaching the ground during the summer is 7,000,000cal/m2/day. The gross productivity of the producers in the salt marsh (mostly microscopic algae) is 0.0040 g/cm2/day. The average rate of respiration (the respiration requirement) is 35% of the gross primary productivity. Ecologists have found that 1 gram of salt marsh producers (the algae) is equivalent to 2,920 calories.
Answers
The algae in the salt marsh are very efficient in their use of the solar radiation they receive.
What is solar radiation?Solar radiation is the energy emitted by the sun in the form of electromagnetic waves. These waves consist of visible light, infrared radiation, and ultraviolet radiation. Solar radiation is important for life on Earth as it provides the energy for photosynthesis and drives the water cycle.
The amount of solar radiation reaching the ground in a salt marsh in Agusan during the summer is 7,000,000cal/m2/day. This energy is used by the producers (microscopic algae) to photosynthesize and produce organic matter. The gross primary productivity (GPP) of the producers in the salt marsh is 0.0040 g/cm2/day. This means that the algae are able to produce 0.0040 grams of organic matter per square centimetre of salt marsh every day.
The respiration requirement for the algae is 35% of the GPP. This means that in order for the algae to survive, they must use 35% of the GPP for respiration. This leaves 65% of the GPP to be used for growth and other metabolic needs.
Finally, ecologists have found that 1 gram of salt marsh producers (the algae) is equivalent to 2,920 calories. This means that 1 gram of algae in the salt marsh contains enough energy to provide 2,920 calories. This indicates that the algae in the salt marsh are very efficient in their use of the solar radiation they receive.

A cross was carried out between pure breed tall pea plant with pure dwarf pea plant and F¹ progeny was obtained
Answers
Answer:
This is an example of a genetic cross in biology, specifically a monohybrid cross. The F1 progeny are the offspring of the cross between the purebred tall and purebred dwarf pea plants, and they exhibit a phenotype (observable physical characteristics) that is a combination of the traits of both parents. This type of cross allows for the examination of dominant and recessive traits, as well as the study of inheritance patterns.
Explanation:
Answer: A cross was carried out between pure breed tall pea plants with pure dwarf pea plants and F¹ progeny is obtained.
Explanation:
When tall plants were crossed with the dwarf pea plants in Mendel’s experiment, then in the first generation i.e. F1 progeny, only tall plants were obtained and no dwarf plant was obtained.
In F2 progeny, there were both tall and dwarf pea plants. The ratio of dwarf and pea plants was found to be 3:2.
In F2 progeny, there were both tall and dwarf pea plants. The ratio of dwarf and pea plants was found to be 3:2 which confirmed that in F2 progeny, both the characteristics were inherited and the tall character of the pea plant was found to be dominative and dwarf to be recessive. This was the law of segregation which says that when plants of different traits were crossed, then in the first progeny only the dominant character was observed whereas, in the F2 progeny, both dominant and recessive traits were obtained.

Answers
The correct answer is C. The role of a centromere is to connect sister chromatids before cell division.
What is cell division?It is the process by which a single cell divides into two or more daughter cells. It is a fundamental process that allows living organisms to grow, develop, and repair tissues. Two types of cell division are : mitosis and meiosis. During cell division, chromosomes need to be replicated and separated into two daughter cells. The replicated chromosomes consist of two identical copies, called sister chromatids, that are held together at the centromere. The centromere is a specialized region of the chromosome where the kinetochore, a protein structure, forms and attaches to the spindle fibers that pull the sister chromatids apart during cell division.

The shaded individuals in the pedigree diagram below are color-blind. The

vision.
What is true about the mother?
A. She must have normal color vision.
B. She must be color-blind.
C. She could be homozygous for normal color vision.
D. She could be heterozygous for color blindness.
Answers
The correct answer is D. She could be heterozygous for color blindness.
What is Color Blindness?
Color blindness is a condition in which a person's ability to perceive colors is impaired. Most cases of color blindness are genetic and are caused by a defect or absence of the color-sensitive pigment in the cones of the retina. This defect or absence can affect one or more of the three types of cones that are responsible for detecting red, green, and blue light.
In the pedigree diagram, the shaded individuals are color-blind, which is a recessive X-linked trait. This means that the individuals in the pedigree who are shaded must have inherited a color-blindness allele from both of their parents, and that the mother of the first generation could be either homozygous for normal color vision (XX) or heterozygous for color blindness (XbX).
If the mother in the first generation had normal color vision, she would have to be homozygous for normal color vision (XX), and all of her sons would also have normal color vision because they would inherit a normal X chromosome from her. However, this would mean that none of her daughters would be color-blind, and there are shaded females in the pedigree. Therefore, it is not possible for the mother to have normal color vision.
If the mother in the first generation is heterozygous for color blindness (XbX), she would have a 50% chance of passing on the color-blindness allele to each of her children. This means that all of her sons would have a 50% chance of being color-blind, as shown in the pedigree, and that her daughters would have a 50% chance of inheriting one copy of the color-blindness allele and being carriers, but they would not be color-blind themselves. This is consistent with the shaded females in the pedigree who are carriers of the color-blindness allele.

What causes the urge to defecate?
Question 11 options:
a stretched rectum
dehydration in the small intestine
muscle movement in the ascending colon
contractions in the ileum
Answers
Answer:
a stretched rectum
Explanation:
The urge to defecate is caused by the stretching of the rectum. The rectum is the last part of the large intestine and it is where feces are stored until a person has a bowel movement.
When the rectum is stretched by the accumulation of feces, the muscles in the rectum walls contract, creating an urge to defecate. This is known as the gastrocolic reflex, and it is the body's way of signaling that it is time to have a bowel movement.
The stretching of the rectum stimulates the nerves in the rectal walls, which then send a signal to the brain to initiate the urge to defecate. The contractions of the rectum also help to move the feces towards the anus, which makes it easier to pass them out of the body.
It is important to regularly have bowel movements to prevent the accumulation of feces in the rectum and maintain good digestive health.

The most common reason that introduced species cause trouble is because they are larger than native species. True or False

The fact that introduced species can result in biological exponential multiplication does not mean that they are a threat to biodiversity.
Biodiversity is defined as the variety of all living things, including various plants, animals, and microorganisms. It is often investigated at three levels: genetic diversity, species diversity, and ecological diversity. We cannot have healthy ecosystems, which we rely on to provide the air we breathe and the food we consume, without a variety of animals, plants, and bacteria. One reason why introduced species are a hazard to biodiversity is that they have the potential to become invasive species that supplant native species and prey on native species, causing unnatural reductions in native species populations. Even if imported species have the potential to multiply biologically exponentially, this does not necessarily entail that they endanger biodiversity.

Estimate the probability of this disorder occurring in the offspring of a marriage between first cousins. Enter your answer as either a fraction or a decimal. Part B Compare this probability to the population at large. Inbreeding increases the probability of this disorder. Inbreeding decreases the probability of this disorder. Inbreeding does not change the probability of this disorder.
Answers
Part A -The likelihood of having Autosomal Recessive Disorder is 1 in 10,000 people = 0.0001.
Part B - Inbreeding increases the probability of disorder.
Autosomal Recessive Disorder inheritance is the way genetic traits or conditions are passed from parent to child. Genetic conditions can occur when a child inherits a mutated (altered) copy of the gene from each parent. Parents of children with an autosomal recessive disorder usually do not have the disorder. Consanguineous offspring may be at increased risk for recessive diseases due to the expression of autosomal recessive gene mutations inherited from a common ancestor.
The following Genotypes can be found in the first two cousins:
A stands for dominant allele.
a denotes a recessive allele.
1) AA X AA
Normal for all offspring.
There are no problems.
2) AA X Aa
Genotype of offspring = AA and Aa.
Because the phenotype is normal, the condition does not exist.
3) Aa X Aa
Genotype of offspring = AA, Aa, and aa.
The condition affects one-quarter of all offspring.
1/4 are typical,
Half of them are carriers.
4) aa X aa
All offspring are afflicted by the condition.
If we assume the cousins to be carriers[because their genotype is not indicated, we will consider them to be carriers], affected kids are generated.
Carriers' probability = 0.02
By 1/2, both cousins are carriers.
And the likelihood that the child may be impacted - 1/4 or 25%
Total Probability is equal to 1/2 * 0.02 * 1/2 * 0.02
= 0.0001
As a result, the pair might have afflicted offspring by 0.0001.
Possessing the normal alleles has no effect on 25% of people; carrying one impacted and one unaffected allele has no effect on 50% of people. Carrying the afflicted Alleles affects 25% of the population.

Red blood cells carry antigens on their surfaces coded for by alleles of the gene designated by the letter i. Ia is dominant to i and produces antigen a on the surface of red blood cells. The ib allele is also dominant to the i allele and produces antigen b on the surface of red blood cells. The i allele does not produce surface antigens.
Answers
Red blood cells carry antigens on their surfaces that are determined by alleles of the gene designated by the letter "i". The Ia allele is dominant over the i allele and produces antigen "a" on the surface of red blood cells.
The ib allele is also dominant to the i allele and produces antigen "b" on the surface of red blood cells. The i allele does not produce any surface antigens. This information can be useful in blood transfusions and understanding the immune system, as an individual with the Ia allele will have red blood cells with antigen "a" on their surface and an individual with the ib allele will have red blood cells with antigen "b" on their surface. These antigens can trigger an immune response if mismatched during a blood transfusion, so it is important to match blood type based on these antigens.

A researcher suggests that the Irish monoculture (growing a single crop) of the Lumper potato did not significantly change the overall resistance of the potato crop in Ireland to diseases. Which of the following observations best refutes this null hypothesis?
A - Before the arrival of the potato blight, there were already two other potato plant diseases in Ireland.
B - The number of fatalities from the Irish potato famine was greater than the rest of the European countries combined.
C - During the early nineteenth century, the vast majority of people in Ireland depended on the Lumper potato for food.
D - Growing more varieties of potatoes increases competition for available resources, which may yield fewer potatoes.
Answers
The number of fatalities from the Irish potato famine was greater than the rest of the European countries combined. Thus the correct answer is option (B).
Irish potatoes' genetic homogeneity made the potato famine that wiped out Ireland's population and economy worse. Evolutionary theory warns against relying on crops with little genetic variety. We might be able to stop significant crop loss caused by shifting environmental circumstances if we pay attention to expert advice and historical lessons. The Irish were able to feed their expanding population in the 1800s by cultivating potatoes. They grew only the "lumper" variety of potato. Furthermore, because potatoes can be replicated vegetatively, all of these lumpers were identical clones. For a while, the lumper gave Ireland food, but it also created the circumstances that resulted in significant economic and social catastrophe. According to evolutionary theory, populations with lesser genetic diversity are more vulnerable to changing environmental conditions than populations with higher genetic diversity. When the ecology of the country changed and a potato disease appeared there in the 1840s, the potatoes (and the people who depended on them) were destroyed. It is likely that the Irish potato clones had little genetic variation.
