Answer:
The food chain describes who eats whom in the wild. Every living thing—from one-celled algaeto giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.
For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.
Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
Answer:
A food web?
Explanation:
Food webs are multiple food chains overlapped. (Usually in the same area)
paracrine signaling
endocrine signaling
direct signaling across gap junctions
Answer:
The correct answer is the third option - endocrine signaling.
Explanation:
The endocrine signaling takes place when endocrine cell organs or glands release hormones that flow through the bloodstream and that act on distantly located target cells in the body. The endocrine system includes several glands that release or secretes different hormones.
The pituitary gland transfers signals to other endocrine glands to release or inhibit their hormone production according to the brain signals. The adrenocorticotropic hormone (ACTH) is released by the anterior pituitary gland that stimulates cortisol release in the adrenal glands in stressed conditions.
Thus, the correct answer is option third - endocrine signaling.
The pituitary gland secreting hormones is an example of endocrine signaling, where hormones are secreted directly into the bloodstream and carried to target cells.
The secretion of hormones by the pituitary gland is an example of endocrine signaling. Endocrine signaling refers to the process where glands secrete hormones directly into the bloodstream, which are then carried to the target cells elsewhere in the body. In contrast, autocrine signaling involves cells responding to their own signals, paracrine signaling refers to cells communicating with nearby cells, and direct signaling across gap junctions involves communication between adjacent cells through specific channels.

Answer:
Plants Produce Oxygen, O2, Which is neccessary for Man to sustain life (Live).
Explanation:
When an atom has fewer neutrons than protons and more electrons than protons, such an atom is said to be an anion. Hence, it is negative ion.
Depending on the number of proton and electron, there are 3 types of atoms:
In this case, the atom has more electrons than protons and, therefore, is an anion. The excessive electron makes such atom to be negatively charge.
Therefore, an atom that has fewer neutrons than protons and more electronsthan protons is a negative ion.

Answer:
Negatively charged ion
Explanation:
Negatively charged ions are called anions and they have more electron than than protons and more protons than nuetrons.
b. has an established daily value that can be followed in a daily menu
c. does not appear to be linked to the development of chronic disease such as diabetes and coronary artery disease
d. a and b
e. none of the above
b. a visit to the dentist
c. a thorough clinical dental exam
d. a medical evaluation of a child or adult
Answer: a. A survey to access the oral needs of school children or adults including a visual inspection of the mouth.
Explanation:
The basic screening survey is a tool which was developed by the Association of the State and Territorial Dental Directors. This is conducted to monitor the oral health of the children as well as the adults. It involves the visual inspection, dental carries, oral examination for the tooth decay and other evaluations related to the oral health.
