Some lipids are formed when fatty acids are linked to glycerol. these subunits are linked together by .
Lipids are formed when fatty acids are linked to glycerol via a process called esterification. This process forms an ester bond between the fatty acid and glycerol, resulting in a triacylglycerol, or a fat.
Explanation:Lipids are formed when fatty acids are linked to glycerol via a reaction known as esterification. This is a dehydration synthesis reaction (a type of condensation reaction) where water is removed, and the fatty acid is bonded to the glycerol.
This process occurs three times for each glycerol molecule, forming a triacylglycerol, or a fat. Specifically, the bond which links the fatty acid to the glycerol is called an ester bond.

Which event marks the end of one menstrual cycle and the beginning of a new cycle?
Answer:
Menstrual flow and ovulation
Explanation:
The menstrual cycle is the hormones regulated the complex process. In this process, endometrium (a thickened lining of uterus wall) ruptures. Rupturing of endometrium results into the menstrual fluid which contains blood, cells from the lining of the uterus and mucus. The flow of menstrual fluid from the vagina is called menstruation. This process is to prepare the woman for expected fertilization.
Menstruation marks the end of one cycle and the release of ova from one of the ovary is beginning of next menstruation that occurs almost 14 days before menstrual flow.
Capillaries are best described as
a. thin walled vessels that convey blood toward the heart.
b. microscopic vessels in which blood exchanges material with the interstitial fluid.
c. thick walled vessels that convey blood away from the heart.
d. thick walled vessels that carry blood rich in oxygen.
e. thin walled vessels that carry blood deficient in oxygen.

Vitamin e protects membranes in red blood cells, white blood cells, nerve cells, and lung cells. why are these cells in particular in need of high amounts of vitamin e?
Answer:
Vitamin E supplements may prevent coronary heart disease , support immune function, prevent inflammation , promote eye health, and lower the risk of cancer.
Red blood cells, white blood cells, nerve cells, and lung cells need high amounts of vitamin E due to their high polyunsaturated fatty acid content and exposure to oxidative stress. Vitamin E acts as an antioxidant, preventing lipid peroxidation in cell membranes and working in conjunction with selenium to maintain cellular health.
The cells such as red blood cells, white blood cells, nerve cells, and lung cells require high amounts of vitamin E because they are particularly susceptible to oxidative damage from free radicals. Vitamin E serves as a powerful antioxidant that protects the polyunsaturated fatty acids present in the cell membranes from oxidation. The cells' high degree of unsaturation in their membrane lipids makes them vulnerable to lipid peroxidation, which can be detrimental to their function and integrity.
Vitamin E, especially in the form of alpha-tocopherol, prevents the oxidation of these fats by acting as a free radical scavenger. It donates electrons to free radicals, stopping the chain reaction of lipid peroxidation. In addition, vitamin E works by sparing or reducing the need for, selenium, which is needed for the activity of glutathione peroxidase, an enzyme that also reduces lipid peroxides and protects the cell membrane. This synergistic action is essential for maintaining cellular health, especially in cells that are exposed to higher levels of oxidative stress, such as lung cells which are constantly in contact with oxygen, and white blood cells that engage in immune responses.

While washing her hair, Olivia noticed that she was losing a lot of hair. She visited a clinic, and the physician reassured her that her hair would grow back. How do you think Olivia’s hair will grow back? The hair will grow back by undergoing regeneration. The hair will grow back by undergoing meiosis. The hair will grow back by undergoing binary fission. The hair will grow back by undergoing mitosis.
The right option is; The hair will grow back by undergoing meiosis.
Meiosis is a type of cell division in which the number of parental chromosome is reduced by half, and there is formation of four haploid daughter cells that are genetically distinct from the parent cell that produced them. Meiosis only occurs when the cell needs to reproduce and it occurs in all eukaryotic, sexually-reproducing animals and plants.
Answer:
the hair will grow back from undergoing mitosis

Research shows that Mount Everest grows and average of 4 millimeters each year. How many years will it take to grow 720 millimeters
A. 40
B. 100
C. 180
D.720
Answer:
It will take C. 180 years to grow 720 millimeters.
Explanation:
The research shows that Mount Everest grows and average of 4 millimeters each year.
In order to calculate how many years it will take to grow 720 millimeters, we need to divide 720 millimeters by the average of 4 millimeters each year.
If we calculate it :
[tex]\frac{720mm}{4\frac{mm}{year}}=180years[/tex]
We found out that it will take 180 years. Therefore, the correct option is C. 180

Organs _____.
only exist in animals
are less complex than the tissues which make them
perform functions that tissues cannot carry out on their own
are made of only one type of tissue
Answer:
perform functions that tissues cannot carry out on their own
Explanation:
In the hierarchy of living system organs come after tissues and before organ systems. Hence, organs are complex then tissues and perform functions that tissues wont be able to perform on their own.
A organ is made up of various types of tissues. They can be divided into two categories, main tissue and sporadic tissue. Main tissue or parenchyma is unique to that organ and defines the function of the organ. For example: Cortex and medulla together form the main functional tissue in kidney. Similarly, myocardium is the main tissue of the heart. Sporadic tissue has blood vessels, nerves and connective tissues.

Hypothesize what potential impact a mutated egfr allele will have on a cell
Mutated EGFR can lead to cancer (especially lung cancer).
A mutation in EGFR is associated with uncontrolled tumor growth, which can accelerate cancer progression.
Epidermal Growth Factor Receptor (EGFR) receptors are found on the surface of tumor cells and their role is to send a growth signal to the nucleus of the cell. Some lung cancer tumors may contain a mutation in their DNA that affects the EGFR. The tumor is said to be "positive for EGFR mutations".
Tumor cells with EGFR mutations are highly sensitive to cancer treatments called "Targeted Therapies" or "EGFR Tyrosine Kinase Inhibitors".
