One structure that can be found is most plant cells is chloroplast. A plant cell may have around 0 to 20 chloroplast, depending on their location in plant or their function.
Chloroplast is the structure that photosynthesis occurs. Photosynthesis is the method that plant make food for themselves. They turn sunlight into food such as starch.
Plants are autotrophs, which means they make food themselves, they don't need food from other sources like animals. Therefore, chloroplast is not found in animal cells because we are heterotrophs, we feed on other food.
The menstrual cycle is practically controlled by a system of hormones that is necessary for reproduction, and when the hormone reaches a heightened level, something called estradiol is made, then the stimulation of the ovaries by a luteinizing hormone.
Once that hormone begins developing, the ovaries make an egg that quickly becomes an ovum. The ovary then releases one egg or two during ovulation. The endometrium (the part that sheds its own cells for the menstruation) peaks after ovulation and changes the lining of the uterus to prepare for the hectic process of pregnancy and child labor.

Answer:
The citric acid cycle is fundamental to produce the energy needed for aerobic cell metabolism, thereby mutations in the enzymes involved in this metabolic pathway would be lethal to the individual
Explanation:
In aerobic organisms, the citric acid cycle (also known as the Krebs cycle), is a key metabolic pathway used to remove electrons and uses them in the electron transport chain in order to generate adenosine triphosphate (ATP), the energy currency of the cell. The citric acid cycle depends on eight enzymes that oxidize acetyl-CoA into two molecules each of carbon dioxide (CO2) and water (H2O). Thus, the citric acid cycle is a series of chemical reactions that are key to breakdown carbohydrates, fats and proteins into CO2 and H2O in order to produce energy (ATP).
Answer: The peptide sequence that is essential for protein insertion, orientation in membrane and for travelling into particular organelle is called a topogenics.
Explanation: Integral membrane proteins are found in all cellular membranes and carry out many of the functions that are essential to life. The membrane-embedded domains of integral membrane proteins are structurally quite simple, allowing the use of various prediction methods and biochemical methods to obtain structural information about membrane proteins.
