Answer;

an orange that has a prolonged shelf life

Explanation;

-Genetic engineering is the process of manually adding new DNA to an organism. The goal is to add one or more new traits that are not already found in that organism.

-Examples of genetically engineered (transgenic) organisms currently on the market include plants with resistance to some insects, plants that can tolerate herbicides, and crops with modified oil content.

-Genetic engineering works by physically removing a gene from one organism and inserting it into another, giving it the ability to express the trait encoded by that gene. It is like taking a single recipe out of a cookbook and placing it into another cookbook.

What is the general formula for fatty acids?
notsponge [240]

Answer:

Fatty acids are long chain carboxylic acids, they contain the carboxyl, COOH, functional group. The general formula for a fatty acid is R-COOH where R represents a long hydrocarbon chain. If the hydrocarbon chain, R, contains only single bonds between the carbon atoms, the fatty acid is said to be saturated.

An action potential triggers the release of synaptic vesicles into the synaptic cleft by _____ channels, allowing _____ ions to
noname [10]

Answer:

1. opening Voltage gated channels

2. Calcium

Explanation:

The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.

The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.

The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.

Thus, opening Voltage gated channels and Calcium is the correct answer.

Describe TWO environmental consequences, other than those related to the loss of boreal forest habitat, that result from the ext
Morgarella [4.7K]

Answer: The greenhouse gas emissions from the extraction of bitumen and the use of large quantities of water.

Explanation:

Bitumen is a natural flammable organic matter formed from kerogen in the process of petroleum generation, which is soluble in carbon disulfide. Asphalt and mineral wax are examples of hydrocarbons which are part of bitumen. Conventional oil is extracted by wells while <u>oil sands deposits are extracted using surface mining sectioning techniques, or are flowed to wells by in situ techniques that reduce bitumen viscosity by steam and/or solvents.</u> So, unlike crude oil extracted in oil wells, bitumen requires an open-pit mining operation, in which large tracts are washed with a mixture of water and chemicals to separate the bitumen from a mixture of sand and clay.

Two consequences of this practice are:

  • The greenhouse gas emissions from the extraction of bitumen are larger than the extraction of conventional oil. The emissions produced contribute  to enhance the greenhouse effect and cause global warming. The greenhouse effect occurs when certain gases retain part of the energy emitted by the earth's soil when heated by the sun's radiation. This phenomenon occurs naturally, and thanks to it, the average temperature of the Earth is about 14º C (57.2 °F). The problem occurs when these greenhouse gases increase in the atmosphere and the amount of energy that is not released into space also increases and, with it, the Earth's temperature.
  • The extraction of bitumen from oil sands requires the use of large quantities of water, and even though water used here can be recycled, only a small amounts is returned to the natural cycle. Also, spills from the transportation of the oil could damage soils and waterways, increasing water pollution. This toxic water  could get into surface.

Sidana [21]
1. theyre opposite because during photosynthesis CO2 is absorbed by plants and during respiration CO2 is emitted.
2. glucose is made during photosynthesis and serves as food for every (!) animal, and animals decompose glucose to CO2 during cellular respiration.
