Fed [463]

Answer:

These are the basic steps of urine formation.

Explanation:

The first step comprises creating a filtrate in the glomerulus.

During the second stage, the filtrate flows through the tubules, and useful substances are reabsorbed.

Waste products will then be secreted by the tubules.

Whereas, the final stage is the conservation of water that occurs in the renal tubule.

There are four major stages in the formation of urine.

Which cell organelle determines if an organism is an autotroph?
otez555 [7]
The correct answer is chloroplast. If an organism has chloroplasts then it will be an autotroph because it will be able to make its own food by the means of photosynthesis. This is common for plants but there are some bacteria that can photosynthesize as well. If you don't have them you have to feed on other organisms that have energy for you.

Can you guys please help me I have a test tomorrow
shtirl [24]

Answer:

11. b.

Explanation:

Photosynthesis stores energy in carbohydrates, cellular respiration releases energy from carbohydrates.

Glucose, C₆H₁₂O₆, is a carbohydrate.

Write out the equations:

<u>Photosynthesis</u>

carbon dioxide + water + light energy => oxygen + glucose/sugar

CO₂ + H₂O + light => O₂ + C₆H₁₂O₆

The carbohydrate is stored in the plant until it needs it, like to perform cellular respiration.

<u>Cellular Respiration</u>

oxygen + glucose/sugar => carbon dioxide + water + ATP energy

O₂ + C₆H₁₂O₆ => CO₂ + H₂O + ATP

The carbohydrate is used to make energy. Energy is released from carbohydrates.

Glucose, C₆H₁₂O₆, is a carbohydrate.

Fault in other options:

a. Photosynthesis and cellular respiration both occur in plants. Plants have mitochondria for cellular respiration.

c. Photosynthesis uses carbon dioxide and cellular respiration releases carbon dioxide.

d. Photosynthesis uses carbon dioxide, cellular respiration uses oxygen.

An enzyme that breaks DNA, dispels the tension, and reseals the strand ahead of a DNA replication growing fork is called a(n):
qaws [65]

Answer:

Topoisomerase

Explanation:

Topoisomerases are enzymes that produce changes in the topology of the DNA during replication, transcription, traduction, or reparation processes. They can cut one or both strands and in order to relieve torsional stresses in the supercoiled structure of DNA. With this, they help to maintain the chromosome's integrity. There are two types of topoisomerases: topoisomerase I (it cuts only one strand of DNA) and topoisomerase II (it is able to cut both strands of DNA).
