It must be fixed or converted by bacteria in the ground into a useable form for plants called nitrates
Answer:
The description regarding the central nervous system(CNS) control of the Autonomic nervous system (ANS) is correctly matched below.
Explanation:
The central nervous system(CNS) is composed of the brain (which consists of the hypothalamus, brainstem and cerebral cortex) and the spinal cord. The rest of the nervous tissues that is found throughout the body make up the peripheral nervous system which is further divided into somatic nervous system and autonomic nervous system (ANS).
Below is parts of the Central Nervous System(CNS) with the correct description of how it controls the autonomic nervous system (ANS):
1. Cerebral Cortex: This is the part of
--> Emotions can invoke autonomic responses
--> sexual thoughts or images can increase blood flow to the genitals.
2. Hypothalamus:
--> It activates the fight-or-flight response
--> it's the major control center of the ANS. it's the integrating center for thermoregulation
3. Brainstem:
--> it's the integrating centers for reflexes controlling heart rate and blood pressure
--> it's the integrating center for the pupillary reflex.
4. Spinal Cord:
--> it's the integrating center for urination, defecation, erection, and ejaculation reflexes.
Answer;
Kingdom Eubacteria
A unicellular kingdom that does not have a nucleus would belong in the kingdom Eubacteria.
Explanation;
Kingdom Eubacteria is the kingdom of prokaryotic, single-celled organisms that lack a membrane-enclosed nucleus and can be classified by shape.
Prokaryotes are organisms that lack nucleus and other membrane bound organelles, such as mitochondria. Unicellular means that the organism is made of one cell.
Based on the four demographic characteristics relating to biotic potential, humans generally have a low biotic potential.
<h3>What is biotic potential?</h3>
Biotic potential refers to the maximum reproductive capacity or potential of an organism under optimum environmental conditions.
The demographic characteristics relating to biotic potential are:
- usual number of offspring per reproduction- it contributes to low biotic potential because humans usually produce one offspring per reproduction
- chancesof survival until age of reproduction - contributes to high biotic potential since humans have high chances of survival
- how often each individual reproduces - contributes to low biotic potential since humans have usually reproduce at least once every nine months
- age at which reproduction begins - contributes to a low biotic potential since humans begin to reproduce at a later age of at least 12.
Therefore, humans generally have a low biotic potential.
