Answer:

Meiosis

Explanation:

Pollen grains are produced through the process of meiosis, during which cells divide and grow in number. The grains of pollen are often located in pollen sacs on the ends of the stamen which is the male parts of the flower, which typically surround the carpel; the female parts of the flower

The digestive tract is essentially one long tube. Write down order of the structures

Angelina_Jolie [31]

Answer:

It consists of the mouth, or oral cavity, with its teeth, for grinding the food, and its tongue, which serves to knead food and mix it with saliva; the throat, or pharynx; the esophagus; the stomach; the small intestine, consisting of the duodenum, the jejunum, and the ileum; and the large intestine, consisting of the cecum, a closed-end sac connecting with the ileum, the ascending colon, the transverse colon, the descending colon, and the sigmoid colon, which terminates in the rectum. Glands contributing digestive juices include the salivary glands, the gastric glands in the stomach lining, the pancreas, and the liver and its adjuncts—the gallbladder and bile ducts. All of these organs and glands contribute to the physical and chemical breaking down of ingested food and to the eventual elimination of nondigestible wastes.

In the citric acid cycle, the enzyme succinate dehydrogenase catalyzes a reversible reaction using FAD/FADH2 as an oxidizing/red

Aliun [14]

The statement which best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions is; Choice D: The change in the biochemical standard reduction potential is small.

Discussion:

A reversible process is one in which the system and environment can be restored to exactly the same initial states that they were in prior to when the process occurred, if we go backward along the path of the process.

However, the necessary condition for a reversible process is therefore the quasi-static requirement.

The quasi-static requirement in this case is that the change in the biochemical standard reduction potential is small.

Drag each label to the correct location on the chart. Classify each process as weathering or erosion. PLEASE HELP me (I'm stuck)

Andreas93 [3]

Lets do numbering of the labels to make labelling clear.

1. The Colorado River carves land in Arizona to form the Grand Canyon.

2. Cracks form in a sandstone wall surrounding a house.

3. A marble statue near the science museum is changing color due to rainfall.

4. After a rainstorm, soil and rock pieces litter the roadways.

5. The sand dunes in the Sahara Desert are changing shape.

Answer:

Weathering:

2. Cracks form in a sandstone wall surrounding a house.

3.A marble statue near the science museum is changing color due to rainfall.

Erosion:

1. The Colorado River carves land in Arizona to form the Grand Canyon.

4. After a rainstorm, soil and rock pieces litter the roadways.

5. The sand dunes in the Sahara Desert are changing shape.

Explanation:

Weathering and erosion, in both the processes rocks are broken down into particles but both the processes are different from each other. Weathering can be physical, chemical or biological process in which rock particles degrade without any movement while erosion is purely a movement of sediments in which particles move from one place to another under the influence of water and wind.

So, on the basis of this difference we can classify each label to the correct location:

Weathering (no movement of particles after degradation):

2. Cracks in a sandstone wall of a house.

3. Changing color of marble statue due to rainfall.

Erosion (Movement of particles from one place to another):

1. Formation of Grand Canyon, when the Colorado River carves land in Arizona.

4. Soil and rock pieces litter on roadways after rainstorms.

5. Changing shape of dunes in sahara desert.
