Which of the following is an example of the endocrine system maintaining homeostasis? (3 points)
-Detecting a pain stimulus and sending a signal to the spinal cord to perform an automatic response
-Discharging an excessive amount of hormones in the blood and not sending a signal to stop production
-Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low
-Using sense organs to get information about the outside world and direct an appropriate body response release
Answers
Answer:
-Discharging an excessive amount of hormones in the blood and not sending a signal to stop production
Explanation:
Endocrine system is regulated by negative feedback mechanisms that work to maintain homeostasis.
Concentration of hormones, and how they effect other body systems, are controlled in this manner.
For instance, the blood glucose regulation is controlled by insulin and glucagon, hormones produced by the pancreas.

Answers
About the question:
You will find the model of the cell cycle in the attached files
Answer:
A. Arrow 1 represents interphase, and Arrow 2 represents mitosis.
Explanation:
When we talk about the cell cycle, we refer to the interphase and the cell division (mitosis or meiosis).
Interphase: Represented by arrow 1.
The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.
• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures also double. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi complex and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
• During the S stage, the DNI replication process occurs. This is the only stage in which the DNI molecule replicates. The synthesis of histones and other associated proteins also occurs.
• G2 stage is the interphase last step. DNI molecule begins to slowly condensate. The centrioles duplication process completes. The spindle fibers get assembled.
Once the whole interphase is completed, mitosis occurs.
Mitosis: Represented in the cycle by arrow 2.
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced. During mitosis, the whole-cell first duplicates and then separates. Mitosis is divided into four phases (these phases are shown in the cycle with different gray color tones). During prophase, chromosomes condensate, and the nuclear membrane breaks. During the metaphase, fibers of the spindle apparatus take chromosomes toward the equatorial cell plane, where they line up. Sister chromatids are holden together until they reach the Anaphase, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole. Finally, cytokinesis occurs.

How does a single fertilized egg cell develop into all the different cells of your body? Use cell division and differentiation in your answer.
Answers
Answer:
Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.
Explanation:

A zygote is formed when an egg is fertilized. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation.
What is Differentiation?This is the process in which cells acquire different structure and function from one another to form distinct cell types.
When a zygote is formed, cell division takes place which helps to trigger differentiation of cells.

The ovarian cycle is the monthly series of changes that occur in a female's ovaries, specifically in the development and release of an egg (ovulation).
The cycle is regulated by several hormones produced by the hypothalamus, pituitary gland, and ovaries, and is divided into three main phases: the follicular phase, the ovulatory phase (or ovulation), and the luteal phase.
