why do farmers use a mixture of manures and fertilizers in the field
Answer:
Farmers use a mixture of manures and fertilizers in the field for several reasons. These reasons are primarily related to soil health, crop yield, and environmental sustainability.
Soil Health
1. Nutrient Supply: Both manure and fertilizers provide essential nutrients to the soil that are necessary for plant growth. Manure, which is organic matter derived from animal waste, is rich in nutrients such as nitrogen, phosphorus, and potassium. Fertilizers, on the other hand, are typically synthetic substances that contain specific proportions of these same nutrients. By using a combination of both manure and fertilizers, farmers can ensure that their soil has a balanced nutrient profile.
2. Soil Structure: Manure also contributes to the physical structure of the soil. It increases the soil's ability to hold water and improves its texture, making it easier for plant roots to penetrate. This is not something that synthetic fertilizers can do.
3. Microbial Activity: Manure is also beneficial because it promotes microbial activity in the soil. These microbes play a crucial role in nutrient cycling and help make nutrients more available to plants.
Crop Yield
4. Increased Productivity: The use of both manure and fertilizers can lead to increased crop yields. The nutrients provided by these substances promote healthy plant growth, leading to more productive crops.
5. Sustained Yield Over Time: Using a combination of manure and fertilizers can also help sustain high crop yields over time. This is because manure helps improve the long-term health and fertility of the soil, while fertilizers provide a quick boost of nutrients that can be immediately used by plants.
Environmental Sustainability
6. Recycling Waste: Using manure as a fertilizer allows farmers to recycle animal waste, turning it into a valuable resource.
7. Reducing Chemical Use: By using manure in addition to synthetic fertilizers, farmers can reduce their reliance on chemical inputs. This can have benefits for the environment, such as reducing runoff pollution.
8. Promoting Biodiversity: The use of organic matter like manure can also promote biodiversity in the soil, which has benefits for the overall ecosystem.

Suppose Maria wants to breed parakeets that are yellow with patterned feathers. However, when she bred several parakeets that were yellow with patterned feathers, she found that there were four different offspring phenotypes.
Phenotype Number
patterned yellow wings 18
solid yellow wings 6
patterned white wings 6
solid white wings 2
Number of genes and alleles?
2 genes; 2 alleles each
1 gene; 4 alleles
4 genes; 1 allele each
Which phenotypes are coded for by the same gene? Different genes are separated by semicolons?
yellow and white; patterned feathers and solid
yellow and patterned feathers; white and solid
all by the same gene
each by a separate gene
Answer:
Explanation:
First let's define a few things.
An allele is a variant form of a gene, each gene can have two or more possible alleles, one inherited from each parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known as alleles. A given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual. Alleles can sometimes result in different phenotypes (observable traits), with certain alleles being dominant. (overriding the traits of other alleles)
Let's make a table of our bird's alleles.
We can see from the phenotype of her bird's offspring, yellow is dominant over white, and patterned is dominant over solid.
Let's use Y for dominant yellow, w for recessive white, P for dominant pattern, and s for recessive solid. I know dominant and recessive traits usualy use the same letter with recessive traits being lower case, but in this case it makes it easier to determine phenotype.
Our parent birds are dihybrid cross which involves 2 genes coding two traits, with dominant yellow pattern both represented by PPssYYww.
So look at the chart. It has then been color coded by the traits the bird will exhibit. We have:
9 birds with Patterned Yellow Wings
3 birds with Solid Yellow Wings
3 birds with Patterned White Wings
1 bird with Solid White Wings
This is the same ratio Maria found in the phenotypes of her birds.
Now we can answer the questions:
Number of genes and alleles? We can see that there are 2 genes, one gene for pattern, and one gene for color, but there are also 2 alleles the variant of the Pattern and the variant of the color.
Which phenotypes are coded for by the same gene?
yellow and white; patterned feathers and solid - This one as you can see from the phenotype chart, and as discussed earlier, there are 2 genes, one for color, the other for pattern.
yellow and patterned feathers; white and solid
all by the same gene
each by a separate gene
Pyruvate dehydrogenase deficiency is a genetic disease most commonly linked to a mutation in the a -subunit of the mitochondrial enzyme that causes the enzyme to cease functioning. As a result of the mutation, affected individuals build up dangerous amounts of lactic acid. Which of the following best explains the buildup of lactic acid in individuals with the mutation?
a. Cells use lactic acid to shunt electrons from pyruvate to the electron transport chain in the mitochondria.
b. Cells undergo glycolysis because there is a buildup of pyruvate in affected individuals.
c. Cells cannot transport pyruvate to the mitochondria in the absence of pyruvate dehydrogenase activity, so the pyruvate is broken down to lactic acid and ethanol
d. Cells undergo fermentation because pyruvate cannot be metabolized to proceed into the Krebs cycle.
Answer: The correct option is D ( Cells undergo fermentation because pyruvate cannot be metabolized to proceed into the Krebs cycle).
Explanation:
Pyruvate dehydrogenase is the enzyme that converts pyruvate to acetyl CoA which enters the Krebs cycle in glucose metabolism. The deficiency of Pyruvate dehydrogenase can be caused by genetic origin most commonly linked to a mutation in the a -subunit of the mitochondrial enzyme that causes the enzyme to cease functioning. As a result of the mutation, affected individuals build up dangerous amounts of lactic acid.
The increase in the level of lactic acid occurs due to the Increased action of lactate dehydrogenase enzyme. In the absence of Pyruvate dehydrogenase enzyme, the level of blood pyruvate increases. Excess pyruvate is then converted to lactic acid by lactate dehydrogenase enzyme in a process called lactic fermentation. This results in a buildup of lactic acid in the blood leading to a condition called lactic acidosis .
Therefore, cells undergo fermentation because pyruvate cannot be metabolized to proceed into the Krebs cycle.

which of the following correctly lists the progression of species present during primary or secondary succession? fungi, nonvascular plants, gymnosperms, animals nonvascular plants, angiosperm, gymnosperms, fungi animals, fungi, nonvascular plants, angiosperms angiosperms, nonvascular plants, animals, gymnosperms gymnosperms, angiosperms, fungi, nonvascular plants
the following correctly lists the progression of species present during primary or secondary succession : fungi, nonvascular plants, gymnosperms, animals.
There is a similar progression of species in both primary and secondary succession, beginning with fungi, then nonvascular plants, gymnosperms/angiosperms, and animals.
Primary succession occurs when newly exposed or recently found rock is colonized for the first time by living things. Secondary succession occurs when a previously occupied area by living creatures is disturbed and then re-colonized. Primary succession is the method by which a community emerges in an otherwise lifeless area devoid of soil. Secondary succession occurs after a disruption that demolishes a community but does not destroy the soil.
Both primary and secondary succession are dominated by smaller primary producers with fewer animals present. Both of these producers alter the landscape, allowing other species to thrive.

Which one of the following is a trait that increases the chances of survival for an endangered species?
A: large size
B: long life span
C: widespread distribution
D: small number of offspring
Option C is correct : widespread distribution is a trait that increases the chances of survival for an endangered species
An endangered species with a widespread distribution has a greater chance of survival than a species that is confined to a small, isolated area. A widespread distribution allows a species to occupy multiple habitats, increasing their chances of finding food, water, and other resources needed for survival. It also reduces the risk of natural disasters or human activities affecting the entire population at once.
While a large size or a long life span may provide some advantages for an individual, they do not necessarily increase the chances of survival for an entire endangered species. In fact, a species with a small size or a short life span may have a higher reproductive rate and adaptability, allowing them to recover more quickly from population declines.
