Answer:
C. Population shrinks; 15 birds in the end
Explanation:
Let us understand some of the given terms;
immigration is a form of migration in which organisms comes into a territory.
emigration is a form of migration in which organisms leaves a place
population is a group of organisms of the same species
Given:
Population = 21 birds
Immigrant = 3 birds
Emigrants = 9 birds
Population change = total number of birds + immigrant - emigrants
= 21 + 3 - 9
= 15 birds
The population will shrink giving 15 birds in the end
An exothermic action releases heat.
Answer: Antipararell strands
Explanation:
The feature of the DNA is antipararell strands
Continuous and discontinuous replication is as a result that the two strands in a DNA molecule runs antipararell, which means one strand run in the 5' to 3' direction, while the other is in the 3' to 5' direction.
The strand which is discontinuously synthesized is referred to as the lagging strand.
Discontinuously synthesized strand produce small DNA molecules attached to its own primer RNA called the okazaki fragments.
Answer: Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins, along with your liver that makes a digestive juice called bile, which helps digest fats and some vitamins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. It also absorbs water with other nutrients. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.
Explanation:
Mouth. The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
Vascular plants reproduce with seeds, nonvascular plants do not, therefore it is C.
