The cuticle maintains salt balance in a marine environment.b. The cuticle provides protection against predators.c. The cuticle prevents water loss in a terrestrial environment.d. The cuticle allows for improved gas exchange.

Answer:
The humans are the dominant consumers. They influence food chains and food web through agriculture, production of energy, habitat destruction, pollution, hunting, and overfishing. This is generally done in order to fulfill the demands for food and shelter along with the growth of population. In long term, it influences aquatic and soil ecosystems.
In case if due to human activities if one community of animals gets extinct then there will be a chain reaction of animals getting extinct. The animals live in harmony to thrive and without which it will proliferate into more extinct animals. Ultimately the majority of the animals will no longer be alive.

Transcription occurs along a 3'-5' template forming an mRNA in the 5'-3' direction.
WHAT IS TRANSCRIPTION:
- Transcription is the process by which a mRNA molecule is synthesized from a DNA template.
- Transcription occurs in the nucleus of eukaryotic organisms where the information stored in the DNA molecule is used to produce a complementary mRNA sequence that conveys it to the ribosome.
- Transcription occurs in the 3'-5' direction, and since the mRNA molecule is complementary, it'll be in the 5'-3' direction.
Therefore, transcription occurs along a 3'-5' template forming an mRNA in the 5'-3' direction.

Answer:
3' to 5'; 5' to 3'
Explanation:
The DNA strand with 3' to 5' polarity serves as a template for the process of transcription. Using the 3' to 5' DNA template strand, the enzyme RNA polymerase catalyzes the formation of RNA. The ribonucleotides are bonded together by phosphodiester bonds that are formed in 5' to 3' direction only. The formation of RNA occurs in 5' to 3' direction. The DNA template strand has a complementary nucleotide sequence to the newly synthesized RNA.

Final answer:
Bill needs to solve a system of linear equations based on the nutritional content of each food item in order to find out how many cups of rice, tofu, and peanuts he should consume to meet his specific nutritional goals. Keep in mind the caloric density of foods and the importance of a balanced diet.
Explanation:
To determine the number of cups he should eat, we would first need to set up a system of linear equations based on the nutritional content of each food item.
Let's denote R as the number of cups of rice, T as the number of cups of tofu, and P as the number of cups of peanuts. From the information given, we can create these equations:
42R + 4T + 34P = 350 (for carbohydrates)
0R + 11T + 75P = 311 (for fats)
1R + 23T + 35P = 168 (for proteins)
He needs to solve this system of equations to get the values of R, T, and P. Keep in mind, nutritional goals are important but it's also vital to consume foods high in micronutrients, fiber and have a balanced diet. Remember that fatty foods are calorie-dense compared to carbohydrates and proteins, meaning they have more calories per unit mass. This can be a healthy and sustainable meal plan for Bill if he also incorporates sufficient fruits, vegetables, and exercises regularly.

Monosaccharides
Fatty acids and glycerol
Amino acids
Water
Ca2+ , Na+ , Ca2+
Answers
Answer:
The absorption of monosaccharides takes place via facilitated and cotransport mechanism and is transported through blood capillaries present in the villi.
The absorption of glycerol and fatty acids takes place through diffusion and the majority of them are transported via lymph capillaries, while some are transported through blood capillaries.
The absorption of amino acids takes place via a cotransport mechanism with sodium ions and is transported through blood capillaries.
The absorption of water takes place by the process of osmosis via diffusion and is transported with the help of blood capillaries.
The absorption of calcium and sodium ions takes place via an active transport mechanism, while the absorption of chlorine takes place via the process of diffusion. The transportation of all these ions takes place with the help of blood capillaries.
Final answer:
Monosaccharides, amino acids and ions are generally absorbed through active transport into the blood capillaries, while fatty acids and glycerol are transported into the lymphatic capillaries. Water is absorbed via osmosis into both the blood and lymph capillaries.
Explanation:
The absorption mechanisms of the various food breakdown products are different and determine whether they move into the blood capillaries or into the lymphatic capillaries. This absorption is either through passive or active transport.
- Monosaccharides like glucose are absorbed through active transport into the blood capillaries.
- Fatty acids and glycerol are also absorbed into the cells lining the small intestine, they are then reassembled into fats and transported into the lymphatic capillaries.
- Amino acids are absorbed through active transport into the blood capillaries.
- Water is absorbed mainly via osmosis, a type of passive transport, into both the blood and lymph capillaries.
- Ions (Ca2+, Na+, Ca2+) are absorbed through active transport into the blood capillaries.
