True, the inner cell mass of the blastocyst becomes the embryo, while the outer cell layer of the blastocyst forms part of the placenta.
What is a blastocyst?A blastocyst is a fertilized egg's clump of dividing cells. It's an embryo in its early stages. A blastocyst is one of the steps that lead to pregnancy.
Five to six days after a sperm fertilizes an egg, a blastocyst develops. Cell layers of the blastocyst divide and separate. They will eventually evolve into structures that will safeguard and nourish the developing embryo.
A fertilized egg's blastocyst stage is critical for in-vitro fertilization (IVF). IVF is the procedure of developing an embryo outside of the body of the birthing parent in order to aid in pregnancy.

What is the shortest part of the cell cycle?
The M phase of the cell cycle is referred to as the shortest phase. The stages of a cell's life that make up the cell cycle.
The cell cycle consists of four major stages: gap 1 (G1), synthesis (S), gap 2 (G2), and mitosis (M). Occasionally, cells will also enter a stationary phase known as G0 after exiting the cell division cycle.
Mitosis is the cell cycle's shortest stage. Cells grow and perform their functions within the body for the majority of their lives during the G1 phase.

water being pulled into the roots by osmotic pressure provides the force needed to raise water to the highest leaves in a plant. a. true b. false
It is false that "Water being pulled into the roots by osmotic pressure provides the force needed to raise water to the highest leaves in a plant" because the vacuum created by the loss of water form the leaves is what causes the pull.
Transpiration is basically a process of water evaporation through the specialized openings in the leaves which are known as stomata. This evaporation of water creates a negative water vapor pressure which is developed in the cells which are surrounding the leaf.
Due to this water is pulled inside the leaf from the vascular tissue, which is the xylem in order to replace the water which has transpired from the leaf. This pulling of the water, or we can say the tension, builds up a negative water pressure. Finally, the negative water pressure that occurs in the roots will result in an increase of water uptake from the soil.

what is the name of the follicle that achieves full maturity under fsh stimulation and then forms a thin-walled blister on the surface of the ovary?
The follicle that achieves full maturity under FSH stimulation and then forms a thin-walled blister on the surface of the ovary is called the Graafian follicle.
The Graafian follicle, a mature ovary-based structure named after the pioneering Dutch physician Regnier de Graaf, embodies the epitome of fertilization readiness.
Stimulated to full maturity by the potent hormone follicle-stimulating hormone (FSH) produced by the anterior pituitary gland, the Graafian follicle swells to a staggering 20-25mm in size, its walls transforming into a delicate and vulnerable blister-like state.
At the peak of its maturity, the Graafian follicle ruptures, releasing the egg into the waiting arms of the fallopian tube in a triumphant ovulatory burst, ready for potential fertilization.
In the absence of fertilization, the remnants of the Graafian follicle transmute into the corpus luteum, which wields hormonal power to regulate the intricacies of the menstrual cycle.

Electron transport, the Krebs cycle, and glycolysis are the three primary biochemical pathways of cellular respiration.
A series of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily reactions. Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three main processes that take place during cellular respiration. In the cytoplasm, glucose is first broken down into pyruvate, a three-carbon compound.
The pyruvate is then transported into the mitochondrial matrix, where it undergoes a conversion process known as pyruvate oxidation. Pyruvate dehydrogenase does this by converting three-carbon pyruvate to two-carbon acetyl-CoA. Acetyl-CoA joins a four-carbon oxaloacetate to create the six-carbon citrate, which starts the TCA cycle.

the likelihood of osteoarthritis affecting a single joint is ______________ that of rheumatoid arthritis.
The likelihood of osteoarthritis affecting a single joint is Lower that of rheumatoid arthritis.
Osteoarthritis is a degenerative condition which impacts a single joint. It is caused by the deterioration of the cartilage, which ordinarily acts as a buffer between the bones, resulting in pain, rigidity, and swelling.
On the other hand, rheumatoid arthritis is an autoimmune disorder in which the body's own immune system mistakenly attacks the joints, leading to inflammation and harm to the joint tissue. This is a systemic issue, meaning that it can influence various joints throughout the body.

over a period of several years, a large hospital kept track of the number of births of babies displaying achondroplasia, a rare condition caused by an autosomal dominant allele that results in dwarfism with abnormal body proportions. after 120,000 births, it was noted that 27 babies had been born with achondroplasia. one physician was interested in determining how many of these dwarf babies resulted from new mutations and whether the apparent mutation rate in this geographical area was higher than normal. he looked up the families of the 27 dwarf births and discovered that 4 of the dwarf babies had a dwarf parent. what is the apparent mutation
Let's assume that the total number of births from families without a dwarf parent is 120,000 - 4 = 119,996.
The number of dwarf births from families with a dwarf parent is 4.
The number of dwarf births from families without a dwarf parent is 27 - 4 = 23.
Therefore, the apparent mutation rate is 23 / 119,996 = 0.000192 or 0.019%.
This apparent mutation rate is higher than the normal mutation rate for achondroplasia, which is estimated to be around 1 in 15,000 to 1 in 40,000.
What is achondroplasia?
Achondroplasia is a hereditary condition that affects bone growth in the body and results in improper cartilage and bone development. As a result, they are short-statured, have short arms and legs, and have larger-than-average heads. It is the most prevalent type of dwarfism and is brought on by a hereditary FGFR3 gene mutation. As a dominant genetic illness, achondroplasia increases the likelihood that one of the parents will pass the gene to their offspring by 50%.
