What is the likely origin of chloroplasts

Answers

Answer 1
Answer: Chloroplast is once a single cell organism, a prokaryotic cell that will engulf in a eukaryotic cell. This eukaryotic cell containts a mitochondria that is developed inside a eukaryotic cell. After the two cell engulf, photosynthesis takes place which makes the prokaryotic cell evolves into a chloroplast organelles.

Answers

It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosisproduces new cells, and replaces cells that are old, lost or damaged. In mitosis a cell divides to form two identical daughter cells.
Mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same.

Which of the following processes does not occur in both plant and animal cellsPhotosynthesis

Anaerobic respiration

Aerobic respiration

Cellular respiration

Answers

Answer:

The correct answer would be photosynthesis.

Photosynthesis is the process by which occurs only in plants and not in animal cells. Rest of the processes can occur in both plants as well as animal cells.

It is the process by which plant cells synthesize their food (glucose) from simple substances such as carbon dioxide and water in presence of chlorophyll and sunlight.

Chlorophyll is an essential element for the process of photosynthesis which is present in plant cells but absent in animal cells.

Final answer:

Photosynthesis does not occur in both plant and animal cells, while anaerobic respiration, aerobic respiration, and cellular respiration occur in both types of cells.

Explanation:

The process that does not occur in both plant and animal cells is photosynthesis. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Animal cells do not have chloroplasts, the organelles required for photosynthesis, so they cannot perform this process.

On the other hand, both plant and animal cells undergo anaerobic respiration and aerobic respiration. Anaerobic respiration occurs in the absence of oxygen and is less efficient than aerobic respiration. Aerobic respiration requires oxygen and is the most efficient way for cells to produce energy.

Cellular respiration refers to the overall process by which cells generate energy from glucose. It includes both anaerobic and aerobic respiration. Therefore, cellular respiration occurs in both plant and animal cells.

What quadrant is the number –14 – 5 located on the complex plane?I
II
III
IV

Answers

I think the correct answer from the choices listed above is the third option. The points (–14, – 5) is located in quandrant III of  a complex plane. This is because both values are negative and from the plot the points in the said quadrant are all negative.

Genes are segments of a chromosome that are responsible for specific hereditary traits. Please select the best answer from the choices provided.a. True
b. False

Answers

True. Genes are part of chromosomes and they contain DNA. Inheritance of traits occurs when genes - discrete units that can be inherited - are passed along in reproduction, from parents to offspring. Alleles are variant forms of genes that give rise to differences between people.

Answers

The correct answer is a dichotomous key. Basically, you use the key to decide what species an organism is by looking at what traits it has, and if it doesn't have some traits you can instantly rule out a large number of species which brings you closer to your answer of what the species is that you're looking at.
