what is a difference between a lens and a mirror

Answers

Answer:

hi

Explanation:

The lens is a material made of glass or plastic bounded by two surfaces. ... A mirror is a reflector that is shiny from one side and reflects the light rays coming from the object to make it appear as an image to the other side. The lens is of two types viz: Concave lens and convex lens.

have a nice day

Answer:

The difference between mirror and lens lies in how light reflects when falls over their surface. When light interacts with any surface, mainly two things happen; Reflection and Refraction. The main difference between mirror and lens is that image forms by reflection, as the light falls on a mirror. In lens, the image is formed by refraction.

Metabolic acidosis can occur as a side effect of taking acetazolamide because: Select one: a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized. b. chloride ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized. c. bicarbonate ions are wasted when sodium is reabsorbed into the tubule as it attracts hydrogen ions. d. chloride ions are wasted when sodium is reabsorbed into the tubule as it attracts hydrogen ions.

Answers

Answer:

a. bicarbonate ions are wasted when sodium is excreted into the urine, leaving behind acidic metabolic waste products that need to be neutralized.

Explanation:

Metabolic acidosis is an electrolyte disorder characterized by a pH of less than 7.40 and low bicarbonate (HCO3) levels in the blood. This disease may be due to 1-an increasing acid production, 2-loss of HCO3 (which acts as an acid buffer agent), and 3- by a decreasing ability of the kidneys to maintain normal acid levels. The kidneys contribute to maintaining the acid–base balance by excreting hydrogen ions (H+) into the urine and absorbing HCO3 from the urine. In metabolic acidosis, kidneys are unable to remove enough acid and conserve sodium ions (Na+), which is normally done by excreting ammonia in the urine.

Colorblindness is an X-linked recessive disorder. If Abby has normal vision (but her father was colorblind) and Ryan is not colorblind. What are the chances that their daughter is colorblind? SHOW ALL WORK FOR CREDIT. (To insert a table in your answer if necessary click on the three dots, click on the icon that looks like a table and you can customize the number and type of boxes you need)​

Answers

Answer:

Let ‘Xᶜ’ be the recessive allele for colour blindness and ‘X’ be the normal (dominant) allele.

Since Abby's father was colour blind, Abby must be a carrier for the same.

Which means Abby's genotype would be ‘XXᶜ’.

Now, Ryan is not colourblind which means his genotype would be ‘XY’.

Now, talking about their daughter, she would inherit a normal ‘X’ from Ryan and either ‘X’ or ‘Xᶜ’ from Abby.

Which means she wouldn't be colourblind but she might be a carrier of the disorder.

XXᶜ × XY

⬇️ ⬇️

X, Xᶜ X

↘️ ↙️

XX , XXᶜ

Their daughter will have either XX genotype or XXᶜ genotype.

And her chances of being colourblind thus, becomes zero.

Has the change in the environment (in this case the food preference of predators) caused natural selection to start occurring in this fish population?

Answers

Answer:

Yes.

Explanation:

Yes, change in the environment conditions leads to the initiation of natural selection in this fish population if the food preference of the predators changes because changes in the food preference of predator causes lowering of population which can't be eaten by the predator earlier. Changing rainfall and drought patterns reshaping the population and existence of fish by availability of type of food to predators which ultimately leads to natural selection among population of fish.
