Disinhibition of the lateral geniculate nucleus may be responsible for vivid visual hallucinations in what condition?
a) behavioral variant frontotemporal dementia
b) schizophrenia
c) Alzheimer's disease
d) peduncular hallucinosis
Answer:
d) peduncular hallucinosis
Explanation:
One of the most striking symptoms of perpendicular hallucinosis is the existence of very vivid, colorful, and recurrent visual hallucinations. These hallucinations occur due to lesions of the brainstem and thalamus, which can influence a disinhibition of the lateral geniculate nucleus. The hallucinations provoked can be very debilitating for the person suffering from this illness and can completely disassociate him from reality.

As a result of this process, offspring 1 and offspring 2 will have *
(2 Points)
Answer: A
Explanation:
they will have different traits because they will each have different dna but the same amount of genes
Offspring 1 and offspring two will have the same number of genes but different traits. So, the correct option is A.
How the same number of genes?When a sperm fertilizes an egg cell, each parent contributes 23 chromosomes with genetic information to the offspring. This means that each cell of the offspring's body has 23 chromosomes that contain instructions for their development, including their traits.What are the different traits?Parents pass on traits, such as eye color and blood type, to their offspring through their genes. Some health conditions and diseases can be passed on. Sometimes, one characteristic has many different forms. For example, blood type can be A, B, AB, or O.Eye color is based on the amount of pigment melanin in the iris. Every gene has an allele from its parents, so many variations are possible. Because of this, even if parents have blue eyes, offspring can have brown or green eyes, or one offspring can have blue, and others can have different eye colors from their family.Thus, we can conclude that two offspring will have the same genes but different alleles.

Which structure is the first to collect the urine?
→ Metabolic waste is considered urine first in the collecting duct of the nephron. From the collecting duct, the urine will travel to the minor and major calyces and then the renal pelvis before leaving the kidney via the ureter.
I hope it's helps ╮(＾▽＾)╭
#CarryonlearningThe structure that is the first to collect urine is the calyx. The correct option is B.
What is calyx?The name "calyx" refers to the flower's outermost whorl. The calyx is made up of sepals because they serve as the calyx's functional building blocks.
Urine travels through the renal calyces, which are kidney chambers. The apex of the renal pyramids is surrounded by minor calyces. Each pyramid's renal papillae are surrounded by a little calyx that collects urine from that particular pyramid.
A major calyx is formed when several minor calyces come together. Urine travels from the main calyces into the renal pelvis and then into the ureter. The majority of the sepals' color is green, and they serve to shield the flower's internal organs from damage, mechanical harm, and desiccation.
Therefore, the correct option is B) calyx.

Marco is given an immortal cell line of epithelial cells to dilute. The initial concentration is 12.5 million cells. If he does four 1:10 serial dilutions, what will be the concentration of the last serial dilution
Answer: 12.5 x 10^6/10000 = 1250 cells.
Explanation:
A serial dilution is the step-by-step reduction of the concentration of a solution. Usually, the dilution factor at each step is constant, resulting in a geometric progression of the concentration, which is logarithmic. Serial dilutions are used to create very dilute solutions by accurately reducing the concentration of a substance.
It is usually carried out in experiments where highly dilute solutions are needed, for example, those involving logarithmic scale concentration curves or those used to determine the density of bacteria. To do this, prepare several test tubes with, for example, 9 ml of dilution liquid and first add 1ml of the undiluted sample to the first tube and then make serial dilutions in the following tubes. The first tube will contain a 1:10 dilution, the second 1:100, the third 1:1000, the fourth 1:10000 and so on.
Use 1 ml of undiluted (stock) solution with a pipette into the first test tube, containing 9 ml of a liquid, which can be for example water, Phosphate-buffered saline (PBS) and mix. This is the 1:10 solution. For the second dilution, take 1 ml of the dilution from the 1:10 tube and add it to the 9 ml of liquid to make the 1:100 tube and mix. The third tube is prepared with 1 ml of the 1:100 solution and 9 ml of liquid and this will be the 1:1000 dilution. The last one is prepared with 1 ml of 1:1000 and 9 ml of liquid and it will be 1:10000 (the fourth dilution).
So, if you start with 12.5 million cells and dilute four times with serial dilutions of 1:10 each, the final concentration will be four times lower:
12.5 x 10^6/10000 = 1250 cells.
The inheritance of genetic traits from parents to children follows predictable rules. Knowing that each parent contributes genes equally to each child, what determines an inherited trait such as eye color? Select one: a. Only the interaction between dominant genes. b. Only the interaction between recessive genes. c. The interaction between dominant and recessive genes does not determine inherited traits. d. The interaction between dominant and recessive genes.
Answer:
The correct answer is - D. The interaction between dominant and recessive genes.
Explanation:
The inheritance of genetic traits come from both parents and based of their gene it can be predicted what traits might found in the offspring. There two types of traits of a single gene, known as alleles. These alleles can be dominant which means they can mask the effect of another allele if present together. The allele that get masked by the dominant allele called the recessive allele. The interaction of both recessive and dominant alleles determines an inherited trait such as eye color.

The correct sequence of Mitosis are Interphase – Prophase – Metaphase – Anaphase – Telophase. Therefore, Anaphase happens after metaphase. So, the correct option is D.
What is Mitosis?Chromosomes that have been duplicated are split into 2 new nuclei during the cell cycle phase known as mitosis. Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Hence, equational division is another name for mitosis.
A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. The cell's contents are often evenly separated into two daughter cells with identical genomes after mitosis.
Interphase, Prophase, Metaphase, Anaphase, and Telophase are the proper phases of mitosis. Anaphase therefore follows metaphase.
Therefore, the correct option is D.
