How do cells in an embryo become different types of cells?

Answers

Answer 1

Answer:

The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. During cleavage, the zygote divides but maintains its size in the process. ... Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.

Explain your observations. What did you observe as you added phenolphthalein to the ammonia solution? What did you observe when vinegar was added?

Answers

Answer:

Liquid ammonia is liquefied ammonia and is basic in nature. It dissolves in water to give ammonium hydroxide which ionizes to give hydroxyl ions. Therefore it turns red litmus blue and phenolphthalein solution pink.

In chloroplasts, when the two photosystems work in series, electrons ejected from the photosystems do not return to them, which is known as ______. Multiple choice question. oxygenic photophosphorylation cyclic photophosphorylation noncyclic photophosphorylation NADPH based photophosphorylation

Answers

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.

Answers

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.

What events occur during protein synthesis?

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.

What are uses of water?

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.

Answers

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.

What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells? in your own words nothing from the internet

Answers

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.
