what organelle processes and sorts proteins to be shipped

Answers

Answer: The Golgi apparatus

Explanation: The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell.

The organelle that processes and sorts proteins to be shipped is the Golgi apparatus. The Golgi apparatus is a stack of flattened sacs that is located near the nucleus of the cell.

It is responsible for processing and sorting proteins that have been made by the endoplasmic reticulum. The Golgi apparatus modifies proteins, packages them, and then ships them to their final destinations.

The Golgi apparatus has three main functions:

Modification: The Golgi apparatus modifies proteins by adding sugars, phosphates, and other molecules to them. This modification changes the properties of the proteins and makes them more functional.

Sorting: The Golgi apparatus sorts proteins into different vesicles. These vesicles are then transported to different parts of the cell, where the proteins are used.

Shipping: The Golgi apparatus ships proteins to different parts of the cell by fusing the vesicles with the cell membrane.

What evidence of climate change on continents supports the theory of continental drift?

signs that glaciers existed in South Africa
similar coal fields on different continents
change in atmospheric temperature over time
same animal fossils found on different continents

Answers

Answer:

A

Explanation:

Edge2022

The evidence of climate change on continents that supports the theory of continental drift is similar coal fields on different continents. Hence option B is correct.

What is continental drift theory?

The theory of continental drift suggests that the Earth's continents were once joined together in a single landmass called Pangaea, which began to break apart around 200 million years ago.

This idea was first proposed by German scientist Alfred Wegener in the early 20th century, who noticed the striking similarities between the coastlines of Africa and South America.

Coal is formed from the remains of plants that lived millions of years ago, and its distribution can provide clues about how continents were once connected.

Coal fields found on different continents that match in age and composition indicate that the continents were once joined together in a larger landmass.

This supports the theory of continental drift, which states that the continents were once part of a single supercontinent that later broke apart and drifted into their present positions.

This evidence suggests that coal-forming swamps once existed in locations that are now separated by oceans and that these locations were once connected.

Hence option B similar coal fields on different continents is correct.

Which organism carries out autotrophic nutrition

Answers

Answer:

Autotrophs is the answer

Example : plants

Plants and some bacteria (e.g., cyanobacteria) carry out autotrophic nutrition, synthesizing their own organic molecules using light or inorganic substances.

Organisms that carry out autotrophic nutrition are capable of producing their own organic compounds and energy sources using inorganic substances. One example of an organism that performs autotrophic nutrition is plants. Plants possess specialized structures called chloroplasts that contain chlorophyll, a pigment responsible for capturing sunlight energy.

Through the process of photosynthesis, plants convert carbon dioxide and water into glucose, a form of stored energy. This energy is then used by the plant for growth, development, and other metabolic processes. Additionally, some bacteria and protists are also capable of autotrophic nutrition. These organisms utilize different mechanisms such as chemosynthesis or photosynthesis to synthesize their own organic compounds and derive energy from non-organic sources, such as inorganic chemicals or light, respectively.

Answers

Answer: 3

Explanation:

Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow. But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits. Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems. Understanding the Nitrogen Cycle—how nitrogen moves from the atmosphere to earth, through soils and back to the atmosphere in an endless Cycle—can help us grow healthy crops and protect our environment.
