“Golden rice is a genetically modified, biofortified crop. ... Golden rice is genetically modified in order to produce beta carotene, which is not normally produced in rice. Beta carotene is convereted into Vitamin A when metabolized by the human body. We need Vitamin A for healthier skin and immune system”
Prokaryotic bacteria are surrounded by a cell membrane that contains the transport proteins to regulate the entry and exit of materials through the cell, the cell wall to help maintain cell shape and structure, and the capsule, which aids against drying out and protects bacteria from a host's immune system.
<h3><u>Explanation:</u></h3>
Bacteria are the prokaryotic organisms that are found in every part of Earth. These organisms do have an interesting ultrastructure. The coverings of the bacteria are three in layer. They are
A. The outer capsule.
B. The middle cell wall.
C. The inner cell membrane.
The capsule is the outermost covering of bacteria that is formed of different slimy materials. These materials contains hygroscopic substances which can absorb water from the surroundings even when the water concentration in outside is very very low. This layer of protection outside bacteria help them to protect themselves against drying out at dry conditions.
The middle cell wall is formed of polymers of N acetyl glucosamine and N acetyl muramic acid. This layer is chitin in nature and is strong enough to maintain the shape and size of bacteria irrespective of outer conditions.
The innermost layer of bacteria is cell membrane which is formed of proteins and lipids bilayer and this cell membrane contains different transport for proteins which help in transport of different substances like water and nutrients inside the cell by means of active transport or passive diffusion.

<h2>e) option is correct </h2>
Explanation:
Traveler's diarrhea is an intestinal infection that occurs as a result of eating or drinking contaminated food or water, food handlers who do not wash their hands after they use the bathroom can transmit the infection to people who consume the contaminated food
Due to diarrhea, kidney don't work properly and level of urea increases in blood
Due to the low carbohydrate intake, ketosis occurs in which stored fat is metabolized which results in build up of acids called ketones
If the body starts to use energy sources other than carbohydrates then it means it is using the stored energy, gluconeogenesis fulfills glucose requirement of cell by synthesis of glucose from non carbohydrate material
To supply with energy lipid metabolism occurs, fatty acids are oxidized and energy in the form of ATP is produced
Answer:
<h2>
Gastrin: stomach,
</h2><h2>
CCK- SI,
</h2><h2>
Insulin- pancreas,
</h2><h2>
Glucagon-pancreas. etc</h2>
Explanation:
1. Gastrin: secreted by stomach stimulating activity of the stomach
,
2. CCK: secreted by SI stimulating secretion of pancreatic enzymes; contraction of gallbladder and pyloric sphincter and inhibitory effects on stomach
3. Secretin: secreted by SI if material entering SI is acidic, triggering secretion of HCO₃-
.
4. Insulin: produced by beta-cells of pancreas and
stimulates storage of glucose in liver and muscle and it causes re-uptake of glucose when blood-sugar is high, lowering blood sugar
5. Glucagon- produced by alpha-cells of pancreas and
it stimulates release of glucose from liver when blood-sugar is low, and results in raising blood sugar.
