A component of the cell that collects freshly generated proteins and other materials from the endoplasmic reticulum wraps them, and transports them to other areas of the cell is called the Golgi apparatus. The correct option is B.
What is the Golgi apparatus?Golgi apparatus is an organ of the eukaryotic cells. It is an irregular-shaped organ. It was discovered by Camillo Golgi. That's why its name is Golgi apparatus.
There are many functions of this organ. It helps in the packaging of proteins and lipids molecules. These proteins are then transported to other parts of the cell.
Thus, the correct option is B. Golgi apparatus.

Answer: The answer would be B
Explanation: All plants and animals release at least some amount of co2 into the atmosphere during cellular respiration
Both plants and animals release carbon dioxide into the atmosphere during cellular respiration can be determined based on the Carbon cycle model. So, the correct option is B.
What is Carbon cycle?The exchange and recycling of carbon in the Earth's biosphere, lithosphere, hydrosphere and atmosphere is known as the carbon cycle. All living things contain the element carbon, which is also an important component of many important compounds such as proteins, lipids, and carbohydrates.
Photosynthesis, respiration, combustion and weathering are just a few of the different processes that make up the carbon cycle. Plants use photosynthesis to take up atmospheric carbon dioxide and convert it into organic molecules. Plants and other organisms then use these molecules as a source of energy.
Therefore, the correct option is B.

What is the subject of a memoir? A. an experience or period in the author’s life B. a significant historical event C. a fictional adventure story D. an analysis of a certain topic
A. An experience or period in the author’s life.
Explanation:
A memoir is a story about an experience in someones life, but it has to be factual. A memoir can not be based on fiction, it has to be real and nonfictional.
Memoirs are usually told in first person, as it is recounting the occurrences that happened in ones life. It is different from an autobiography, as autobiographies usually focus on the whole lifespan of a person, while a memoir focuses on one topic or event that happened.
Memoirs also usually focus on personal growth throughout the writing, are truthful and keep track of the persons goals and influences.

which is not an example of inorganic fertilizer? A.nitrogen fertilizer B.phosphorus fertilizer C. Livestock waste
Answer:
Livestock waste
Explanation:
Fertilizers supplement the soil with macronutrients needed in large amounts: nitrogen, phosphorous and potassium. However, organic and inorganic fertilizers do so via different materials. Organic fertilizers contain only plant- or animal-based materials that are either a byproduct or end product of naturally occurring processes, such as manures, leaves, and compost.
Inorganic fertilizer, also referred to as synthetic fertilizer, is manufactured artificially and contains minerals or synthetic chemicals. For example, synthetic nitrogen fertilizers are typically made from petroleum or natural gas. Phosphorus, potassium and other trace elements in inorganic fertilizers are often mined from the earth. Balanced inorganic fertilizers, high in all three macronutrients, commonly include products like ammonium nitrate, ammonium sulfate, potassium chloride (potash), triple superphosphate, and magnesium sulfate (Epsom salts).

It does not contain chlorophyll which is needed to absorb light or energy.
Answer:
The parts without chlorophyll do not photosynthesise, and so they do not make starch and the iodine does not change colour.
The green parts contain chlorophyll and photosynthesise to make starch.
The white part of the leaf does not contain chlorophyll, so does not photosynthesise.

d. greater biodiversity of wetland species
e. better agricultural conditions in northern Alberta
f. improved air quality in urban areas

Answer:
a. more stable weather conditions --- NE
b. more wheat and less canola grown as crops ---E
c. greater threat to forests from insect pests ----E
d. greater biodiversity of wetland species ----E
e. better agricultural conditions in northern Alberta ----E
f. improved air quality in urban areas-----NE
Explanation:
The climate of Alberto change with the increase in temperature which disturb the weather condition of the region. This increase in temperature decreases the production of wheat crop so more wheat crop is cultivated for fulfilling the needs. This increase in temperature make the environment more suitable for different organisms. The climate is cold during winter so increase in temperature causes condition suitable for agriculture in northern Alberta. Improved air quality in urban areas is not possible due to more production of carbondioxide gas which leads to increase in temperature.

The presence of cosmic microwave background radiation is evidence for the Big Bang theory given by scientists. The correct option is D.
What is Big bang theory?The Big Bang theory exemplifies how the universe came into existence from a high density and temperature starting point.
It is the dominant cosmological model that explains the evolution of the observable universe from its earliest known periods to its subsequent large-scale form.
According to scientists, the universe should be filled with radiation that is literally the remnant heat from the Big Bang, which is known as the "cosmic microwave background," or CMB.

In photosynthesis, plants use _______ and release ________. *
A. carbon dioxide, oxygen
B. oxygen, carbon dioxide
Answer:
A. carbon dioxide, oxygen
Explanation:
Photosynthesis is a process that certain organisms (plants, algae and some bacteria) undergo to produce their own food. The equation for photosynthesis is:
water + carbon dioxide + light energy —> glucose + oxygen
In photosynthesis, the plant takes water, carbon dioxide and light energy from the sun and turns it into glucose (sugar, or the food) and oxygen.
Therefore, the correct answer is A. carbon dioxide, oxygen. The plant will use carbon dioxide and then release oxygen as a waste product.
what is the composition of gastric juice and their functions?
Answer:
Mostly HCl, Pepsin, Lipase, Water, and other Electrolytes
Explanation:
The gastric mucosa secretes 1.2 to 1.5 litres of gastric juice per day. Gastric juice renders food particles soluble, initiates digestion (particularly of proteins), and converts the gastric contents to a semiliquid mass called chyme, thus preparing it for further digestion in the small intestine. Gastric juice is a variable mixture of water, hydrochloric acid, electrolytes (sodium, potassium, calcium, phosphate, sulfate, and bicarbonate), and organic substances (mucus, pepsins, and protein). This juice is highly acidic because of its hydrochloric acid content, and it is rich in enzymes. As noted above, the stomach walls are protected from digestive juices by the membrane on the surface of the epithelial cells bordering the lumen of the stomach; this membrane is rich in lipoproteins, which are resistant to attack by acid. The gastric juice of some mammals (e.g., calves) contains the enzyme rennin, which clumps milk proteins and thus takes them out of solution and makes them more susceptible to the action of a proteolytic enzyme.
Answers:
It is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. It is found in all vertebrates.
Main function is to inactivate microorganisms.
