Why do phospholipids make a phospholipid bilayer with the heads facing out towards water and the tails facing each
Answer: See below
Explanation:
Phospholipids are organized into two layers. The phospholipids have a head known as a 'hydrophilic' or water-loving head. Any water will come into contact with this region of the phospholipid. In contrast, the phospholipid tails are hydrophobic, or 'water hating'. They will position themselves such that they face inwards and are not in touch with any water. Because of these features, the bilayer is created with the phospholipid heads facing outwards and the tails facing inside.

Explain what happens to the available energy within each level when more organisms exist at that level.
Answer:
Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).
Explanation:
Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).
Energy can neither be created nor be destroyed. The available energy within each trophic level is lost as heat and only 10% of the energy is utilized.
The 10% rule can be explained as:
1. Energy in the different trophic levels is passed and the rest of the energy is lost as heat.
2. The law suggests that only 10% of the energy is transmitted to different trophic levels.
3. Approximately 80%-90% of the energy is lost in the form of heat. The organisms utilize energy for metabolic processes and keep them warm.
Thus, the rest of the energy is lost as heat and only 10% of the energy is transferred to the next trophic level.

amylase is a biocatalyst that hydrolyzes starch into simple sugar molecules in the pancreas. Which best describes amylase ?
Answer: The options are not given, here are the options.
A. lipid
B. protein
C. fatty acid
D. carbohydrate
The correct option is B.
Protein.
Explanation:
Protein best describes Amylase because it is an enzyme and Enzymes are biological molecules called protein that speed up the rate of chemical reactions. Therefore amylase is a biocatalysts or protein that breakdown starch into simple sugars molecules in the pancreas like glucose which can easily be absorb by the blood. All enzymes are protein and amylase is an enzyme in the digestive system.

How is carbon dioxide produced in a cement plant
Carbon dioxide is produced in a cement plant when limestone is decomposed.
Cement is produced using lime stone as raw material. The limestone is decomposed according to the reaction;
CaCO3(s) -----> CaO(s) + CO2(g)
The CaO is used to produce cement while CO2 is a waste gas that escapes.
Hence, carbon dioxide is produced in a cement plant limestone is decomposed.

What are Eicosanoids? Discuss the biomedical importance of Arachidonic acid and its derivatives
Explanation:
Eicosanoids are involved in vasodilation and vasoconstriction, promotion of sleep, pain and fever. They pay a role in up- or down-regulating inflammatory cytokines. What eicosanoids cells produce and their effects depend on the type of cell, the tissue in which that cell is found, and the cell's activation state.
Determine the amino acid sequence to AATACGGCC
Answer:
UUA UGC CGG
Explanation:
if its not that is there perhaps a table for the sequences
The amino acid sequence for the given DNA sequence AATACGGCC can be determined by transcribing the DNA into mRNA and then translating the mRNA into amino acids using the genetic code.
The given DNA sequence is AATACGGCC.
The mRNA obtained for this DNA sequence through transcription will be:
UUAUGCCGG.
Using the genetic code, each codon (triplet of nucleotides) is translated into its corresponding amino acid as follows:
1. UUA - leucine
2. UGC - methionine
3. CGG - proline
Therefore, the amino acid sequence for AATACGGCC is Leucine-Methionine-Proline or Leu-Met-Pro.

What three categories of energy expenditure make up the total energy expenditure? Define each briefly. For the average person, how much does each contribute to the overall required?
The categories of energy expenditure include the following:
Resting metabolic rate - This is the total number of calories burned when your body is completely at rest and accounts for 60-75 percentThermic effect of feeding - This happens during feeding in which the metabolic rate increases and heat is produced and accounts for 5-15 percentThe thermic effect of activity - the amount of energy burned during all physical activity and accounts for 15-30 percent.What is Energy expenditure?These are the processes which involves how energy is used or spent.

Which does an organism need to undergo cellular respiration?
A. food and oxygen
B. water and sunlight
C. sunlight and oxygen
D. carbon dioxide and energy
Answer:
C. sunlight and oxygen
Explanation:
Cellular respiration is quite simply the conversion of chemical energy from oxygen into ATP in order to release waste by-products.
Oxygen is needed for this process to take place because it helps break down the necessary nutrients which will in turn generate ATP, and other processes.
Therefore, an organism needs oxygen and sunlight to undergo cellular respiration.

the interactions of abiotic and biotic factors results in condition that are suitable for some oranisms but not for others?
Answer:
Abiotic factors can be extremely broad. Sunlight, air, soil, rock, minerals, water, etc. are all biotic factors. Sunlight provides energy that plants utilize to grow, which ultimately holds up the whole biotic community of an ecosystem. Air also interacts with plants, helping them grow by providing a source of carbon (CO2) and other nutrients.
In general, abiotic factors like rock, soil, and water interact with biotic factors in the form of providing nutrients. Just as humans mine mountains and cultivate soil, rock and soil provide resources for plants, and plants cycle the nutrients through so they (usually) end up back in the ground where they began. The water, phosphorus, nitrogen, and carbon cycles are examples of this.
Another way biotic and abiotic factors interact is that biotic factors often change the geology and geography of an area. Geologically, organisms create topsoil by breaking down rock layers and dying, which provides detritus with which to form new soil and return nutrients to the ground
