Farmers need to make many decisions about how they grow their crops. One of these decisions is whether to use synthetic fertilizer or organic fertilizer, such as manure.
An advantage of using synthetic fertilizer instead of organic fertilizer is that
A synthetic fertilizer can provide more targeted macronutrients to the crops
B) synthetic fertilizer remains in the soil longer than organic fertilizer does, reducing the volume needed and, therefore, the cost to the farmer
c) synthetic fertilizer adds to soil texture and increases the soil's water-holding capacity
organic fertilizer runs off more readily into waterways, leading to nutrient overload
An advantage of using synthetic fertilizer instead of organic fertilizer is that
synthetic fertilizer can provide more targeted macro nutrients to the crops.
Synthetic fertilizers are used by farmers to increase crop yield. The fertilizer
are specially formulated to ensure all the macro-nutrients are present in the
right proportions for optimal yield of the crops.
This is the advantage synthetic fertilizers have as organic fertilizer don't
contain all the targeted macro nutrients in the right amounts.

Which of the following metabolic pathways does NOT directly produce lots of ATP (also called anaerobic cycle)?
A. Glycolysis
B. Krebs cycle
C. Citric acid cycle
D. Electron transport chain
Answer:
A. Glycolysis
Explanation:
Glycolysis is the first stage of cellular respiration, which occurs in the cytoplasm of the cell. Glycolysis does not require oxygen to occur, hence, it is carried out by both prokaryotic and eukaryotic organism.
Glycolysis, among the other stages of cellular respiration, produces the least ATP (2). Hence, Glycolysis is the metabolic pathway that does NOT directly produce lots of ATP.
What are some functions of the Thalamus.
Answer:The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. The primary function of the thalamus is to relay motor and sensory signals to the cerebral cortex
Explanation:
The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that: Are substrate level phosphorylations Are irreversible. Are regulated steps. Operate close to equilibrium. g
Answer:
The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that Are regulated steps.
Explanation:
Glycolisis and gluconeogenesis are two mechanisms related to the carbohydrates metabolism. Sometimes they are considered reverse processes. However, they are different because of the control points they have where reactions are irreversible.
Glycolisis and gluconeogenesis share 7 common reactions, that are reversible. Thses reactions are coordinated and regulated by F-2 and 6-BP as the answer to the hormonal action.
Glycolisis happens in the muscle, while Gluconeogenesis happens in the liver. Together they form the "Cori Cycle".

A 66-year-old man has difficulty controlling voluntary movements. He can clearly state what he intends to do, describe how he would do it, and initiate or stop the movement. However, he has poor coordination and often misses his target. If his difficulty arises from a defect in one particular area of the central nervous system, which area is most likely to be involved
Answer:
Cerebrum
Explanation:
Cerebrum is the part of central nervous system that is responsible for the voluntary movement. If there is poor coordination between cerebrum and the muscles so the person has difficulty in controlling his voluntary actions or movement. Somatic nervous system is a part of the peripheral nervous system responsible for the voluntary movements of body parts through the use of skeletal muscles so we can say that both cerebrum and somatic nervous system is responsible for voluntary actions.

What are some causes of CO2 levels being higher in some areas than others?
Answer:
human activities for example the burning of fossil fuels in cars or the clearing of forests for agriculture or development
In some areas, human activity is high for burning fossil fuels so these areas create more carbon dioxide.
What are the causes of CO₂ levels?Growing concentrations as a result of human activities including burning fossil fuels in vehicles and power plants, and industrial operations.
Destroying forests for development or cultivation may increase carbon dioxide levels because plants consume CO₂ in photosynthesis and during respiration CO₂ released into the atmosphere.
Plants absorb more carbon dioxide via photosynthesis than they emit through respiration throughout the day or in the spring and summer, the amount of carbon dioxide in the air decreases.
Therefore human activities produce more CO₂ by burning fossil fuels some area level is high than others.

Which of the following is the reason in how the anterior pituitary differs from the
posterior pituitary?
O A) the hypothalamus controls the release of posterior pituitary hormones but not the anterior
pituitary
B) the anterior pituitary makes its own hormones; the posterior pituitary releases hypothalamic
hormones
C) the posterior pituitary works independently of the hypothalamus
D) the anterior stores hormones produced by the posterior pituitary
Answer:
B) the anterior pituitary makes its own hormones; the posterior pituitary releases hypothalamic hormones
Explanation:
The pituitary gland is referred to as "master gland" because it coordinates the activities of other endocrine glands. The pituitary gland is composed of two lobes namely: anterior pituitary and posterior pituitary. These two lobes are individually controlled to release several hormones by the HYPOTHALAMUS.
However, one major difference between the anterior and posterior pituitary lobe is that; the posterior pituitary DOES NOT MAKE ITS OWN hormone, hence, releases the hormones (oxytocin and ADH) it stores but produced by the HYPOTHALAMUS. On the other hand, the anterior pituitary PRODUCES ITS OWN hormones but waits for hypothalamic signal to release them.
A random mutation occurs and the GGA codon is changed to CGA, what effect does the substation have on amino acid
Answer:
The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Explanation:
Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into mRNA,called point gene mutations.
In the case presented, the substitution of the guanine base by cytosine in the GGA codon--resulting in a CGA codon--generates a change in the coding amino acid resulting in arginine instead of glycine.
The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.
Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.
All organisms must regulate by turning genes on and off in different cells at different times.
a. True
b. False
Answer:
a. True
Explanation:
The genome can be defined as the complete set of genetic information of an organism which is responsible to produce all the biological components required to carry out its metabolic functions (i.e., development, growth, reproduction, etc). These genes are transcriptionally expressed to produce mRNAs which are subsequently used to synthesize specific proteins (i.e., enzymes and structural proteins) by the process of translation. All organisms (i.e., either unicellular or multicellular organisms) exhibit specific gene expression programs by which such genes are regulated over time. Within the cell, gene regulation is essential to carry out biological processes ranging from development and differentiation to cell cycle arrest. These gene expression programs are acutely regulated via genetic (e.g., transcription factor binding) and epigenetic (e.g., DNA methylation) mechanisms, which work together in order to turn on/off genes during development.

You are tasked with characterizing responses to Epidermal Growth Factor (EGF) treatment of HeLa Cells. You grow HeLa cells then replace the culture media with media containing EGF at various concentrations, then harvest samples for Western blot analysis using an anti-phospho-MAPK antibody as a readout of receptor tyrosine kinase activity. As expected, your control (EGF treated cells) show a strong phopho-MAPK signal on your Western blot. What do you hypothesize will happen if you pre-treat HeLa cells with siRNAs (RNAi) against Ras prior to adding EGF and performing Western blot analysis with anti-phospho-MAPK
Answer:
The answer is "The EGF receptor will be activated but the signal will not be appropriate transduced"
Explanation:
It induces the replication of cell types, especially fibroblasts or epithelial cells. It enhances neuron variety's telling the difference, ripening, and survival. The proinflammatory cytokines of the EGF family are described by four disulfide bonds that confer adhesive properties. The EGF sensor is switched on and the signal is not transmitted correctly.
