During which era did the earth form
Answer:
Hadean Eon
Explanation:
About 4.5 billion years ago, they began to turn into the planets that we know today as Earth, Mars, Venus, Mercury, and the outer planets. The first era in which the Earth existed is what is known as the Hadean Eon.
The formation of the Earth occurred during the Hadean Eon. The Hadean Eon is the earliest geologic eon, lasting from approximately 4.6 billion to 4 billion years ago.
It is named after the Greek god Hades. it reflects the harsh conditions that characterized this early period of Earth's history, including intense heat, volcanic activity, and frequent impacts from asteroids and comets.
The Hadean Eon marks the formation of the Earth, the accretion of its early materials, and the development of its initial atmosphere and oceans. It marks the earliest stage of the Earth's existence.

Imagine taking a bite of a pizza. Briefly discuss the role that each part of the brain takes in this simple act. Medulla, Pons, Cerebellum, Thalamus, Hypothalamus, Amygdala, Hippocampus, Parietal Lobe, Occipital Lobe, Temporal Lobe, Frontal Lobe.
Answer:
- Medulla: transmits signals between the spinal cord and higher brain levels
- Pons: transmits impulses related to the voluntary skeletal movements from the cerebrum to the cerebellum
- Cerebellum: coordinates skeletal muscle contraction, conscious/subconscious movements, maintains muscle posture, and balance
- Thalamus: regulation of the human nervous system
- Hypothalamus: maintains the overall homeostasis of the body
- Amygdala: processes fearful and threatening stimuli
- Hippocampus: regulates learning, memory encoding and consolidation, and spatial navigation
- Parietal Lobe: processes information from the outside world (e.g., touch, taste, temperature)
- Occipital Lobe: interprets information from the eyes
- Temporal Lobes: process sensory information (i.e., pain and auditory stimuli)
- Frontal Lobe: higher cognitive functions (e.g., memory, problem-solving, emotions, impulse control, etc)
Explanation:
The medulla (medulla oblongata) is the lowest portion of the brainstem, which is linked by the pons to the midbrain and continues with the spinal cord. The medulla is known to transmit signals between the spinal cord and higher brain levels, thereby controlling autonomic activities (e.g., heartbeat and respiration). The pons is a mass of transverse nerve fibers that links the medulla with the cerebellum, it transmits signals from the forebrain to the cerebellum. The pons is involved in different functions, e.g., sleep, respiration, hearing, equilibrium, taste, eye movement, swallowing, bladder regulation, facial expression, etc. The cerebellum is a small part of the brain involved in physical movements (e.g., posture, balance, coordination), which receives sensory information from sensory systems, the spinal cord, and different parts of the brain. The cerebrum is the largest part of the brain, it is involved in speech, thinking, reasoning, problem-solving, emotions, initiating/coordinating movements, regulating temperature, learning, etc. The thalamus is a mass of gray matter located in the forebrain which is involved in diverse functions (i.e., relay of sensory signals, regulation of consciousness, sleep, alertness, etc). The hypothalamus is a small, central, area of the brain that connects the nervous to the endocrine system that acts to maintain the overall homeostasis of the body. The amygdala is a structure located in each hemisphere of the brain that processes fearful and threatening stimuli. The hippocampus is a structure located in the depths of the temporal lobe that regulates learning, memory encoding and consolidation, and spatial navigation. The parietal lobe is located at the upper back area in the skull, it is involved in processing sensory information from the surrounding world (e.g., touch, taste, temperature). The occipital lobes are responsible for transmitting visual information to the temporal lobes, and they are also associated with memory skills. The frontal lobe is the most anterior part of the brain, which is involved in higher cognitive functions (e.g., social interaction, motor function, memory, emotions, impulse control, problem-solving, etc).

What renal and hormonal factors will cause an increased release of aldosterone from adrenal cortex?
Answer:
Renin; angiotensin I and angiotensin II
Explanation:
Renin is a key hormone involved in the renin-angiotensin-aldosterone system (RAAS), which is responsible for regulating blood pressure in response to changes in blood volume. Renin is secreted primarily by the kidneys to promote the production of the peptide hormone angiotensin in the blood vessels. Subsequently, angiotensin stimulates the release of aldosterone from the adrenal cortex, stimulating sodium retention by the kidneys. Renin acts on its substrate angiotensinogen to yield angiotensin I, which is then converted to angiotensin II by the angiotensin-converting enzyme (ACE). Finally, angiotensin 2 promotes the release of aldosterone by the adrenal cortex, which acts on renal tubules, leading to the reabsorption of sodium and water and the excretion of potassium.
Amanda does fast once a month, How is the glucose homeostasis in her body maintained while she is
fasting?
A.The blood sugar level decreases while fasting, the alpha cells in Amanda's pancreas releases glucagon into
the blood that stimulates the liver to breakdown glycogen and releases glucose in the blood. In this way, the
blood glucose level rises and maintains homeostasis.
B.The blood sugar level increases while fasting, the beta cells in Amanda's pancreas releases insulin into the
blood that stimulates the liver to take up glucose and convert it into glycogen also the body cells absorb more
glucose. In this way, the blood glucose level declines and maintains homeostasis.
C.The blood sugar level neither increases nor decreases while fasting; the beta cells in Amanda's pancreas
releases glucagon into the blood that stimulates the liver to breakdown glycogen and releases glucose in the
blood. In this way, the blood glucose level rises and maintains homeostasis.
D.The blood sugar level neither increases nor decreases while fasting the beta cells in Amanda's pancreas

Unlike DNA, which typically forms a helical structure, different molecules of RNA can fold into a variety of three-dimensional shapes.This is largely because RNA A)contains uracil and uses ribose as the sugar. B)bases cannot form hydrogen bonds with each other. C)nucleotides use a different chemical linkage between nucleotides compared to DNA. D)is single-stranded. Multiple Choice
Answer: This is largely because RNA is single-stranded. The correct option is D.
Explanation:
RNA ( Ribonucleic acid) is a single stranded nucleic acid which is composed of:
--> A nitrogenous base: RNA consists of four nitrogenous bases which includes adenine, cytosine, uracil, and guanine. Uracil is a pyrimidine that is structurally similar to the thymine, another pyrimidine that is found in DNA (Deoxyribonucleic acid).
--> A five-carbon sugar: it contains ribose as its pentose sugar and
--> A phosphate group.
The main function of RNA is to convert the information stored in DNA into proteins.
RNA strand can undergo significant intramolecular base pairing to take on a three-dimensional structure. This is because it is single-stranded. This is due to the presence of a hydroxyl group at the 2' position of the ribose sugar. The presence of this functional group causes the helix to adopt the A-form geometry rather than the B-form most commonly observed in DNA.
How does the renal portal system differ from the hypothalamo–hypophyseal and digestive portal systems.
Answer:
The correct answer is - The renal portal system has an artery between the first and second capillary bed. The others have a vein.
Explanation:
A portal system is a system in which is used blood collected from one set of capillaries bed passes through a large vessel or vessels, to another set of capillaries bed before returning to the systemic circulation as the heart can not use these to transfer from all the parts of bodies.
There are several portal systems such as the renal portal system, the hypothalamo–hypophyseal and digestive portal systems, however, The renal portal system has an artery whereas others have a vein.

In sexual reproduction, what is true about the DNA of the offspring?
A. It is the same as the fathers DNA.
B. It is a different from either parents DNA.
C. It is the same as the mothers DNA.
Answer:
[tex]\boxed {\boxed {\sf B. \ It \ is \ different \ from \ either \ parent's \ DNA}}[/tex]
Explanation:
Sexual reproduction is one kind of reproduction. It involves two parents to produce offspring. This kind of reproduction occurs when gametes combine. Gametes are sex cells or the egg and sperm. These cells are created in a process known as meiosis. Meiosis is a type of cell division. Cells undergo two divisions and a process known as crossing over. Genetic material is exchanged between two chromosomes, which helps maintain genetic diversity. The 2 divisions result in 4 haploid cells, meaning they have half of the genetic material. After meiosis, there are 4 genetically unique and haploid cells.
When an egg and sperm combine during fertilization, a zygote forms. This is a fertilized egg. It is very unique because each parent contributes half of the genetic material to create a diploid organism with a full set of unique DNA.
You can look similar to your parents and siblings, but (unless you have an identical twin), there is typically some difference because the DNA of offspring is different from either parent's DNA.
