Answer:
Diagram, in attachments
Explanation:
From the left side of the screen to the right,that is from a structure with a sugar structure with two other molecules attached to it.
The first molecular structure is Nucleotides. Reasons it contains the middle ribose sugar(5-carbon)connected to the phosphate group and Nitrogenous bases.This is the structure of nucleotides and when this is joined by phosphodiester bond between one a nucleotide, to the phosphate group of another nucleotide molecule it forms a nucleic acid molecule.
The second structure from left to right with long carbon chains, it is a lipid.That js an Ester formed from the reaction of fatty acids with alcohol glycerol.
However, the presence of Phophate group in structure makes it different from a normal tryglycerides.The phosphate group has replaced one of the the three fatty acid molecules.Therefore it is called Phospholipid.With one hydropholic ends(phosphate ends) and the hyrophobic end the carbon chain,with one unsaturated. The lipids molecules are held together my ester bonds.
The next structure is the protein structure(dipeptide).Genrally amino acid is made up of the central Alpha carbon connected on the right by the Carbonyl group(coo-) on the left by the Amine(NH2) group.The R-group which determines the type of amino acids and hyrdogen atom.In the above structure condensation reaction has occurred between the hydrogen atom of the amine group and carbonyl group of the other amino unit to form a dipeptide.The bond formed from the condensation is the peptide bond.
The last structure on the far right are the carbohydrate -ring structure and the straight chains.The functional groups of the CHO -Carbonyl group and hydroxyl group are glues to this.

Answers
Answer:
Slow Growth
Explanation:
The age structure diagram is a method of understanding the population. It is used by the demographers to estimate the growth, fall, or change in the population of an area. The data required is the distribution of the age and the sex of an area. When the diagram is constructed and made into a pyramidal shape, it represents that there is a rise in the population of the area. a stable population can be estimated by there is straight up and down. The rapid growth model represents a rapid decrease in the population with age. The slow growth model represents a steady decrease in the population with age

b. organic matter absorbs the oxygen from the water
O c. the space occupied by the organic matter reduces the volume that could be occupied by the
oxygen
d. organic matter results in waste heat
Answers
Answer:
A.
Explanation:
Just took the test, and I was told A.
Dumping of organic wastes into a lake may result in anaerobic conditions in the lake because some microorganisms use the organic matter to respire aerobically, reducing the oxygen content of the water.
What do you mean by organic wastes?"Organic waste is any material that is biodegradable and comes from either a plant or an animal."What do you mean by anaerobic conditions?It is a condition when the oxygen level decreases or disappear.Aerobic respiration- It is the process of respiration that takes place in the presence of oxygen gas to produce energy from food.When organic wastes are dumped into lake, the microorganism starts decomposing it by utilizing the oxygen present in water. The disappearance of oxygen is faster than its production by photosynthesis. So, the lake will now have an anaerobic condition.
Hence, the correct option is a. some microorganisms use the organic matter to respire aerobically, reducing the oxygen content of the water."

Answers
i think its ionic bond not sure but ionic means, deffinition: Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds. It is one of the main types of bonding along with covalent bonding and metallic bonding. Ions are atoms with an electrostatic charge.
A double covalent bond joins two oxygen atoms. So the correct option is E.
What is a covalent bond?
When two atoms share an electron pair, it forms an interatomic connection known as a covalent bond in chemistry. The electrical attraction of their nuclei for the identical electrons is what causes the binding. When the linked atoms' combined energies are lower than those of widely spaced atoms, a covalent connection is created.
The inorganic elements hydrogen, nitrogen, chlorine, water, and ammonia (H2, N2, Cl2, H2O, NH3) as well as all organic compounds are examples of molecules with covalent connections. Covalent bonds are denoted as solid lines joining atom pairs in structural representations of molecules.
A single line denotes a bond between two atoms (i.e., one electron pair), a double line (=) denotes a double bond between two atoms (i.e., two electron pairs), and a triple line () denotes a triple bond, such as that found, for instance, in carbon monoxide (CO).
Therefore the correct option is E.

Which statement describes prey? They provide energy for dead organisms. They are killed by predators for energy. They obtain energy from dead organisms. They obtain energy from predators.
Answers
Answer:
the answer is B
Explanation:
The statement that describes prey is they are killed by predators for energy. The correct option is b.
What are prey and predator?Predators are often carnivorous creatures that hunt smaller animals for food. Predators hunt, capture, and eat the animals that make up their prey. When there are more predators in a particular environment, there will be less prey overall.
Predators lose population when they move to new locations in search of food, which increases the population of prey in the area from which they migrated. In other words, a cycle of events starting with a decrease in prey and ending with an increase in prey results from an increase in predators.
Therefore, the correct option is b, They are killed by predators for energy regarding the statement that describes prey.

The mechanism that accounts for high frequencies of sickle cell hemoglobin in malarial environments is:
Answers
Answer:
Selection -Selective advantage
Explanation:
Sickle cell hemoglobin result from the sickle shape of red blood cell instead of the ameboid shaped cell.
Malaria is a deadly disease that result from mosquito bites.
Sickle cell hemoglobin has a selective advantage because of the presence of AS genotype, the s allele in a sickle cell is an harmful recessive allele that remains in the gene pool it becomes expressed when the s allele is expressed in SS form after an AS individual have mated with either an AS or SS individual.
AS genotype has a high resistance against malaria, they have the ability to thrive making the allele s that is recessive for sickle cell thrive well in the environment of malaria in an AS individual.
Which of the following is an efferent neuron that is responsible for releasing a neurotransmitter that stimulates a muscle cell to contract?
a) Motor neuron
b) Sensory neuron
c) Interneuron
d) Neuroglia
Answers
Answer:
A. Motor Neuron
Explanation:
Motor neurons which can also be referred to as the lower/alpha motor neurons, furnishes skeletal muscle and causes the muscle to contract, this thereafter generates movement. Motor neurons releases neurotransmitter acetylcholine at the neuromuscular junction that stimulates muscle cells to contract.
At the point when the acetylcholine ties to acetylcholine receptors on the muscle fiber, an activity potential is proliferated along the muscle fiber in the two ways. The activity potential triggers the contraction of the muscle. On the off chance that the end of the muscle are fixed, keeping the muscle at a similar length, at that point the compression results on an expanded power on the backings which is referred to as isometric contraction. On the off chance that the muscle abbreviates against no obstruction, the constriction brings about steady power which is referred to as isotonic contraction. The engine neurons that control appendage and body developments are situated in the front horn of the spinal line, and the engine neurons that control head and facial developments are situated in the engine cores of the brainstem. Despite the fact that the engine framework is made out of various kinds of neurons dispersed all through the CNS, the engine neuron is the main manner by which the engine framework can speak with the muscles.
Ultimately, every movements will rely on the activity of the alpha motor neurons.
