Answer:

What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells?

Explanation:

1.The cell membrane holds the cell's internal contents from its environment

2.the nucleus, the cell's "brain", holds the cell's DNA in the form of chromosomes, and makes protein codes that tell the other organelles to function in a certain way once the codes are made into literal proteins and passed around the cell

3.The cytoplasm is the gelly fluid inside the cell. It is the place for chemical reaction, and provides a place where other organelles can operate within the cell properly, and the cytoplasm keeps the cells from moving around.

4. The main job of the mitochondria is to convert nutrients into energy through cellular respiration, making ATP. the mitochondria are known as the powerhouse of the cell.  In addition to supplying energy, the mitochondria is involved in a range of other processes,like signalling, cellular differentiation, cell death, as well as control of the cell division cycle and cell growth.

Answer: Bees have a number of specialised adaptations that help them to be great pollinators. Their bodies carry an electrostatic charge that attracts pollen (see photo below). They have special hairs that are arranged to form pollen 'baskets' on their hind legs. These adaptations allow them to carry large amounts of pollen.

Agricultural, Commercial, Public, and Domestic

The three main areas where water may be used in a society is agricultural, domestic and household activities.

Our communities rely heavily on water to function. There wouldn't be any local commerce or industry without water. Public swimming pools, city parks, and firefighting all require a lot of water.

To deliver a consistent supply of water to our taps each day, a variety of pipes, canals, and pumping stations operated by our public water systems are necessary.

Every day at home, the typical American household uses more than 300 gallons of water. About 70% of this use takes place indoors.

Therefore, The three main areas where water may be used in a society is agricultural, domestic and household activities.

Mitochondria are cellular organelles that are in charge of oxidative phosphorylation, which is the critical process of turning nutrients into adenosine triphosphate (ATP) molecules that power normal cell operations. At least hundreds of mitochondria are found in each neuron. Because nerve cells are postmitotic, any mitochondrial damage received will accumulate over time and produce malfunction. Cells die as a result of widespread mitochondrial damage because they can no longer create adequate energy.

The chemiosmotic hypothesis states that the energy for the production of ATP during photosynthesis comes from the Mitochondria.

The mitochondria is regarded as very important and the power(energy) house of the cell as a lot of ATP synthesis activities takes place in this organelle.

The hypothesis was used to prove that most of the ATP production that takes place in respiring cells comes from the electrochemical gradient present  across the inner membranes of mitochondria.

ATP is formed from the break down of the molecules rich in energy such as glucose and the use of energy of NADH and FADH₂ which are formed from its breakdown.

Answer:

The correct sequence of events that occurs during protein synthesis? A

Explanation:

2. DNA is used as a template to create mRNA, which leaves the nucleus

4. mRNA molecule binds to a ribosome

1. tRNA brings the correct amino acid specified by the mRNA codon

3. Amino acids are bonded together to make a polypeptide (protein)

5. The ribosome releases both the mRNA molecule and the polypeptide (protein)

During protein synthesis, all the machinery for synthesis occurs in a sequential manner and the first need is a DNA template, so the correct option is a.

Protein synthesis occurs in the ribosomal machinery and the process is called translation and starts after transcription.

DNA acts as a template for transcription and makes mRNA which translates into protein. mRNA act as a messenger for protein synthesis, this mRNA converts into protein with the help of ribosomal machinery.

In the process tRNA act as an adapter molecule adding an amino acid to the protein chain according to the codon on mRNA. In the last step protein and mRNA are released by the ribosome.

Therefore protein synthesis starts with DNA, hence option a is correct.

Answer:

When the water gets too warm, the algae can no longer live inside corals, so they leave. The corals then turn from green to white, called coral bleaching. Climate change has been causing the Earth's air and oceans to get warmer. With warmer oceans, coral bleaching is becoming more widespread.

Explanation:

When the water temperature rises too high, algae can no longer live inside corals and leave. Coral bleaching occurs when the corals turn from green to white.

A coral reef is an underwater ecosystem characterized by corals that build reefs. Reefs are made up of coral polyp territories hosted along by calcium carbonate.

The vast bulk of coral reefs are mainly composed of stony corals, which have polyps that coalesce together.

Coral reefs grow in shallow water with temperatures ranging from 68° F to 97° F. The Indo-West Pacific biogeographic region contains more than 90% of the world's coral reefs.

When the temperature of the water rises too high, algae can no longer live inside corals and must leave. Coral bleaching occurs when corals alter color from green to white.

The Earth's air and oceans are becoming warmer as a result of climate change. Coral bleaching is becoming more common as the oceans warm.

Thus, this is the effect of water temperature on corals from inshore and offshore reefs.

When electrons do not return to the photosystems, it is because of a process known as oxygenic photophosphorylation, a process that is key to photosynthesis.

Photosynthesis is the process by which plants get their energy. This process involves many steps taken in order to turn energy from light, into sugar and molecular energy known as ATP, needed for plants to survive. This process uses a variety of important and complex steps, among which is included oxygenic photophosphorylation.

Oxygenic photophosphorylation is one of the key processes to photosynthesis. It involves the use of photosystems one and three, located in the thylakoid membrane of plant cells, in order to produce NADPH and ATP. These systems enter a state of photoactivation, releasing an electron to be carried by the NADPH molecule towards the Calvin cycle where the electron can be placed onto a carbon atom, for long-term storage, often as a carbohydrate.
