A cell membrane is very specific about what it allows to cross.how does this help the cell?
Answer:
The cell membrane is selectively permeable . It lets some substances pass through rapidly and some substances pass through more slowly, but prevents other substances passing through it at all. Some small molecules such as water, oxygen and carbon dioxide can pass directly through the phospholipids in the cell membrane
what is mitosis? In detail
Explanation:
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
The major purpose of mitosis is for growth and to replace worn out cells.

Explanation:
Which of the following statements is true? Which of the following statements is true? No archaea are capable of using CO2CO2 to oxidize H2H2, releasing methane. Prokaryotes have low levels of genetic diversity. Archaea and bacteria have identical membrane lipids. The cell walls of archaea lack peptidoglycan.
Answer:
The correct answer is - The cell walls of archaea lack peptidoglycan.
Explanation:
Archaea are the prokaryotes that are different from bacteria in various ways but the most important differences are the membrane lipids and the major component of the cell wall that lacks peptidoglycan found in the cell wall of bacteria.
These prokaryotes are able to use carbon dioxide to oxidize hydrogen, releasing methane. Archaea-like prokaryotes have a high level or complex genetic diversity.

Translate the sequence of amino acids in sickle-cell hemoglobin into (use third valine)
a) mRNA base codes
b) tRNA base codes
c) DNA base codes
Answer:
Sickle cell hemoglobin occurs in the beta chain of hemoglobin due to point mutation in the sixth codon which changes from glutamic acid to valine which is hydrophobic that causes the change in the size of the RBC in a crescent shape.
The protein or amino acid chain of this condition is as follows:
Protein with Sickle Mutation: VAL HIS LEU THR PRO VAL GLU
which is translated from mRNA sequence
mRNA with Sickle Mutation: G U G C A C C U G A C U C C U G U G G A G
mRNA sequence is the complementary sequence or anticodons of the mRNA sequence RNA:
tRNA with Sickle Mutation: C A C G U G G A C U G A G G A C A C C U C
mRNA sequence is transcribed from the transcription strand of DNA sequence:
DNA with Sickle Mutation: C A C G T G G A C T G A G G A C A C C T C
In arthritis, there is deposition of urate crystals in joints. If you want to treat the arthritis by decreasing the concentration of circulating uric acid, what will you do with its mechanism in kidney?
Answer and explanation:
If I'd wanted to decrease the concentration of circulating uric acid by altering its mechanism in the kidney, I would administer a drug that would inhibit uric acid reabsorption and increase its excretion through urine.
Arthritis is a condition characterized by inflammation of the joints and can be caused by many diseases. When the cause of this arthritis is the deposition of urate crystals in the joint because of an increase in the concentration of circulating uric acid (hyperuricemia) we are most likely talking about gout, a painful disease that can deform the joints.
Hyperuricemia and gout have many risk factors associated with them, such as genetic predisposition, unhealthy diet, and suffering from other conditions like Diabetes.
Several medications are used in the treatment of the symptoms and the prevention of the worsening of this disease, but the one that is most frequently used to increase the excretion of uric acid is Probenecid. Probenecid blocks the kidney's OAT (organic anion transporter) that reabsorbs uric acid in the kidney tubules, thus enhancing its excretion and decreasing uric acid's blood concentration.

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).

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.
