Responsible farming and natural solution are needed to get carbon from atmosphere to ground.
What is reponsible farming?
We define "responsible farming" as methods that take into account the sustainability of the environment, animal health and welfare, the wellbeing of farm workers, the safety of the food being produced, and supply chain traceability.
Here are the various farming practises: Farming for milk. Commercial agriculture. Plantation agriculture.
While sustainability is undoubtedly a crucial component of ethical farming, we exclusively use the term to refer to the environment. Other areas of farming, like risk-reducing effective farm management techniques, supply chain traceability to safeguard the integrity of the product, worker safety and well-being, and animal health and welfare, are equally important in our opinion.

8 If all the red-tailed hawks, coyotes, and rattlesnakes are removed from the ecosystem, which BEST predicts the effect on the population of desert cottontails?
A
The cottontail population will experience rapid growth due to a lack of competition for resources.
B
The cottontail population will experience unlimited growth without predators to control their populations.
C
The cottontail population will experience rapid growth without predators but will eventually stabilize due to a lack of resources.
D
The cottontail population will experience growth due to an increase in resources but will eventually stabilize due to increased competition.
Answer:
C
Explanation:
Because there are no more predators in the ecosystem, the cottontails will reproduce with more offspring surviving. As time goes on, resources will be scarce, and the population will decline and stabilize.
Which of the following mechanisms is (are) used to coordinate the expression of multiple, related genes in eukaryotic cells? A) The genes share similar enhancer sequences, which allows appropriate activators to turn on their transcription at the same time. B) Environmental signals enter the cell and bind directly to promoters. C) The genes are organized into a large operon, allowing them to coordinately controlled as a single unit. D) They contain the same promoters.
Eukaryotic cells coordinate the expression of multiple, related genes by having similar enhancer sequences in the upstream region of the gene.
(Option A) The genes share similar enhancer sequences, which allows appropriate activators to turn on their transcription at the same time.Coordinating the Expression of Multiple Genes in Eukaryotic CellsCoordination of the expression of multiple, related genes in eukaryotic cells is achieved through the use of similar enhancer sequences. These enhancer sequences are located in the upstream region of the gene and are recognized by activators that bind to them and regulate the transcription of the gene. By having similar enhancer sequences, multiple, related genes can be turned on at the same time, allowing for the coordinated expression of these genes. This is in contrast to prokaryotic cells, which use operons to coordinated the expression of multiple, related genes.

Which of the following cells is formed by meiosis?
Answer:
Egg or sperm cellmeiosis can only produce egg and sperm cells for sexual reproduction. Meiosis begins following one round of DNA replication in cells in the male or female sex organs. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells

The sperm and the egg are formed by meiosis. The resulting cell contains only half the number of chromosomes as the parent cell so that the original number of chromosomes is restored when they fuse.
6. A sequence of DNA is shown below. Determine the complimentary strand.
7. Can you predict which base comes next in the strand of DNA above? Why or why not?
The complimentary stand sequence would be TGA TAC G.
No, the next base that comes cannot be predicted because there are no theories of laws that can be used for prediction.
DNA sequenceThe complementary sequence of a DNA strand follows the base pairing rule that says that A always pairs with T and G always pairs with C.
Thus, for the DNA strand ACT ATG C, the complementary base sequence would be TGA TAC G.

A lower than normal blood pressure will cause which of the following effects on the rate of plasma clearance of Substance A?
A) An increase, because the concentration of Substance A in the urine will increase
B) An increase, because the ADH levels will be very low
C) A decrease, because the decreased rate of urine output will allow more reabsorption by the kidney
D) A decrease, because ADH levels will be very high
Lower than normal blood pressure will cause which of the following effects on the rate of clearance of substance A is C. A decrease, because a decrease in the rate of urine output will allow more reabsorption by the kidneys
Kidneys are bean-shaped organs located behind the abdomen which function as excretory organs and play a role in blood control. The kidneys control blood pressure through regulation of extracellular fluid volume and renin secretion. Blood pressure can be caused by a lack of fluid which causes blood volume to decrease, causing a decrease in blood pressure.
Decreased kidney function is characterized by a decreased glomerular filtration rate based on measurements of creatinine clearance, caused by low blood pressure thereby reducing the filtration rate of the glomerulus. This causes the amount of substance A to decrease in the urine due to reabsorption by the kidneys.

Which kind of diet helps prevent cancer
A diet high in fruits, vegetables, and whole grains, that is low in processed foods, red and processed meats, and refined grains, is associated with a decreased risk of cancer.
Nutritious diet that includes a variety of fruits, vegetables, and whole grains includes key vitamins and minerals, as well as fiber and other important nutrients that can boost your body's defense against cancer. Eating a diet high in red and processed meats, as well as refined grains, on the other hand, may increase inflammation and free radicals, which may increase risk of certain types of cancer.
The scientific evidence for a correlation between diet and cancer prevention is supported by numerous studies. For example, a 2007 prospective study of over 50,000 people found that individuals with diets rich in fruits, vegetables and whole grains were 20% less likely to develop cancer than those who ate less of those foods. Other epidemiological evidence, as well as laboratory and animal studies, suggests that certain nutrients found in these foods (including natural antioxidants and phytochemicals) may play a role in decreasing cancer risk.

Eye Color is controlled via a polygenic interaction between two genes. They will be represented by gene “a” and gene “b”. The chart below shows how the genes interact with one another to code for a phenotype.
Polygenic Inheritance – Eye Color
Key:
AABB = Black
A-B- = Brown
A-bb = Hazel
aaB- = Green
aabb = blue
If a man with brown eyes(AaBb) mates with a female with green eyes(aaBb), what would be the chance of the following outcomes
Polygenic inheritance refers to traits that are coded by the interaction of several genes. The expected phenotypes in the exposed example are: 6/16 individuals are expected to have Brown eyes (A-B-). 2/16 are expected to have Hazel eyes (A-bb). 6/16 are expected to have Green eyes (aaB-). 2/16 Blue eyes (aabb).
What is polygenic inheritance?
Polygenic inheritance is a non-mendelian inheritance pattern that occurs when a trait results from the interaction of more than one gene.
The interaction between many genes and alleles can cause different combinations that result in phenotypic gradation. This gradation depends on the level of contribution of each allele.
In the exposed example, two diallelic genes are involved in eye color,
