Two control systems of the body
Endocrine and Nervous
Endocrine and nervous system similarities
-Work together to maintain homeostasis
-Release ligands (chemical messengers) that bind to cellular receptors on particular target cells
Endocrine and nervous system differences
Endocrine system: -Transmits hormones through blood
-Targets any cell in the body with the correct receptor
-Very widespread
-Exhibits longer reaction times and has longer-lasting effects
Endocrine System
-Composed of ducts and glands that synthesize and secrete hormones
-Hormones are released into the blood and transported throughout the body
Endocrine system regulation growth and development
-Changes measured from birth to puberty
-Hormones help regulate embryonic cell division and differentiation
-Hormones regulate metabolism
How does the endocrine system maintain homeostasis or blood composition and volume
-Hypothalamus
-Hormones regulate blood solute concentrations (ex glucose ions)
-Hormones regulate blood volume, cellular concentration, and platelet numbers
The endocrine system controlling digestive processes
-Trigger digestion when food is in the stomach
-Hormones influence secretory processes and movement of materials in the digestive tract
Endocrine System controlling Reproductive Activities
-Make sure sperm and egg make it to each other
-Hormones affect the development and function of the reproductive system and the expression of sexual behavior
Endocrine Glands
Contain epithelial tissue that makes and releases hormones within a connective tissue framework
Endocrine Organs
-Glands with solely endocrine functions
-Ex: Pituitary, pineal, thyroid, parathyroid, and adrenal
Endocrine Cells
-Found in clusters in organs with another function
-Examples in Hypothalamus, Thymus, Heart, Stomach, Liver, Pancreas, Small Intestine, Adipose Connective Tissue
-Pancreases is not an endocrine gland, but it does release hormones

Explanation: behavioral barrier
Cornell University recently conducted a study that estimated that honeybees pollinate more than $14 billion worth of crops each year. The study suggested that nearly seventy-five percent of all global crops that are grown for food, fiber, beverages, condiments, spices, and medicines are pollinated. Produced with the help of pollinators, agricultural products including legumes, vegetables, fruits, berries, nuts, herbs, spices, oils, seeds, grains, clover, and cotton make a significant contribution to the economy. As the human population increases, so does the demand for pollination; sadly, the honeybee population is decreasing. Within the past thirty years, parasites, predators, and disease have weakened both wild and managed populations of honeybees. In fact, around the globe, honeybees are being decimated by an epidemic known as colony collapse disorder (CCD).
According to this article, who collected information to research the honeybees?

Cornell University collected the information used to research the honeybees.
Because they create multiple alleles, mutations can cause
A. cell division.
B. damaged DNA to repair itself.
C. overproduction of offspring.
D. variations in traits.
Because they create multiple alleles, mutations can cause D. variations in traits.
Gene mutations and evolutionThe production of mutations in DNA molecules is known as mutagenesis. Changes in DNA sequence or chromosome rearrangement are just two examples of mutations that can occur in DNA. These mutations can happen on their own, as a result of mistakes made during DNA replication or mitosis. Natural selection requires genetic variety, which is produced by spontaneous mutations.
The process by which populations of organisms change over generations is known as evolution. These modifications are caused by genetic differences. Different features in an organism can be introduced by genetic differences that modify gene activity or protein function. If a characteristic is beneficial and helps an individual survive and reproduce, it is more likely to be handed down to the following generation (a process known as natural selection).

nitrogen cycle in steps
“Nitrogen Cycle is a biogeochemical process which transforms the inert nitrogen present in the atmosphere to a more usable form for living organisms.”
Process of the Nitrogen Cycle consists of the following steps –
Nitrogen fixation, Nitrification, Assimilation, Ammonification and Denitrification.
Nitrogen Fixation Process
It is the initial step of the nitrogen cycle. Here, Atmospheric nitrogen (N2) which is primarily available in an inert form, is converted into the usable form -ammonia (NH3).
Nitrification
In this process, the ammonia is converted into nitrate by the presence of bacteria in the soil. Nitrites are formed by the oxidation of ammonia with the help of Nitrosomonas bacteria species. Later, the produced nitrites are converted into nitrates by Nitrobacter. This conversion is very important as ammonia gas is toxic for plants.
Assimilation
Primary producers – plants take in the nitrogen compounds from the soil with the help of their roots, which are available in the form of ammonia, nitrite ions, nitrate ions or ammonium ions and are used in the formation of the plant and animal proteins. This way, it enters the food web when the primary consumers eat the plants.
Ammonification
When plants or animals die, the nitrogen present in the organic matter is released back into the soil. The decomposers, namely bacteria or fungi present in the soil, convert the organic matter back into ammonium.
Denitrification
Denitrification is the process in which the nitrogen compounds make their way back into the atmosphere by converting nitrate (NO3-) into gaseous nitrogen (N). This process of the nitrogen cycle is the final stage and occurs in the absence of oxygen. Denitrification is carried out by the denitrifying bacterial species- Clostridium and Pseudomonas, which will process nitrate to gain oxygen and gives out free nitrogen gas as a byproduct.
