The functional unit of the kidney that filters blood and forms urine is the ____.

Answers

Answer 1
Answer:

The functional unit of the kidney that filters blood and forms urine is the Nephron.

What is Nephron?

Nephron, a functional component of the kidney, is the organ responsible for producing urine as waste and extra chemicals are eliminated from the circulation.

The kidneys (pronephros) of early vertebrate embryos, amphibian larvae, and primordial fish have the most basic nephrons. Only somewhat more advanced in structure are the nephrons present in the kidneys (mesonephros) of frogs, most fish, and more advanced vertebrates during late embryonic development.

The adult kidneys, or metanephros, of land vertebrates like reptiles, birds, and mammals have the most developed nephrons.

Therefore, The functional unit of the kidney that filters blood and forms urine is the Nephron.

Answer 2
Answer:

Final answer:

The nephron is the functional unit of the kidney. It filters blood and forms urine through a process involving the renal corpuscle and the renal tubule.

Explanation:

The functional unit of the kidney that filters blood and forms urine is the nephron. Kidneys contain millions of these tiny structures, and each nephron consists of two main parts: the renal corpuscle and the renal tubule. Blood enters the kidney through the renal artery, which splits to form a vast network of tiny capillaries. These capillaries form a tuft inside a cup-like structure known as the Bowman's capsule, which is a part of the renal corpuscle. The blood gets filtered here, and the filtrate moves into the renal tubule, where essential nutrients are reabsorbed, and wastes and excess water are concentrated into urine to be excreted.

The protist known as an Euglena is sometimes considered an animal-like protist and other times a plant-like protist. Why would scientists classify it as a plant-like protist?a. presence of chlorophyll
b. the way it moves
c. presence of an eye spot
d. none of these

Answers

The correct answer is A. They are classified as a plant-like protist because of the presence of chlorophyll. They resemble plants by having a cell wall, chlorophyll and the capability of carrying out photosynthesis. All plant like protist live in water and have the same reproduction and movement.

Answer:

the correct answer is A.

What is the minimum number of data points an experiment should gather?

Answers

Answer;

3 data points

Explanation;

  • The minimum number of data points that an experiments should gather is 3 points.
  • Data points are discrete units of information in a scientific experiment. In statistics or even scientific experiments a data point is determined by measurement or research and may be represented numerically or graphically.
  • Data points may also refer to information that is gathered in a scientific experiment, that needs to be analyzed for the purpose of deriving possible results or conclusions. An experiment requires a minimum of three data points from which a graphical representation can be obtained from.
The minimum number is 3

Consider the following events of photosynthesis. 1. Light energy excites electrons. 2. Water molecules are split. 3. NADPH is formed. In which locations do each of these events occur? 1. photosystem II 2. photosystem I 3. photosystem I 1. photosystem II 2. photosystem II 3. photosystem I 1. photosystem I 2. photosystem I 3. photosystem II 1. photosystem I 2. photosystem II 3. photosystem II

Answers

Answer: Option B. 1. photosystem II 2. photosystem II 3. photosystem I

Explanation:

Photosynthesis is the process by which plants make their own food in the presence of light utilizing carbon dioxide and water. this process occurs in chloroplast which contains green pigments called chlorophyll.

Photosystem are defined as the cluster of chlorophyll pigments found on the thylakoid membrane ( in chloroplast) which functions to collect energy and concentrate it to reaction center which further uses the energy to excite electrons and pass on to enzymes.

Photosystem II absorbs light and energy which allows the excitation of electrons and creates an electron deficiency in Photosystem II. the deficiency filled by Z protein which contain manganese that stimulates splitting of two water molecules.

NADPH formation takes place in Photosystem I. Photosystem I accepts energy from light which excites an electron and passed on to an electron acceptor called FeS.  FeS then passes its e- to Ferrodoxin which donates its electron to NADP+ reductase. NADP+ reductase donates electron to NADP+ and add a proton  to form NADPH to get stabilized.

Hence, the correct option is B.

Mike grows vegetables on his farm. The tomatoes that he grows are of good quality, but they are small. What can he do to increase the size of the tomatoes?

Answers

To increase the size of the tomatoes, one thing he could do is to prune side stems. These are the new branches that grow from the main stem of the plant which signifies overgrowth. Overgrowth will mean that these leaves will not get enough sunlight to grow bigger and also it weighs down the plant. However, when you take out these side stems more of the leaves are exposed to the sun thus they make more energy for the plant which then produce larger fruits.
