1. Give one example of an organic substance.
2. Which inorganic substances does a plant use to make carbohydrates?

Answers

Answer:

1)Carbohydrates 2)Green plants make their own food. They use simple inorganic substances – carbon dioxide, water and minerals – from the air and soil.

Answer: examples- carbohydrates, liquids, proteins, nucleic acids. plants use carbon dioxide, water, and minerals to make carbohydrates

Explanation:

Summarize photosynthesis and describe how it is part of the carbon cycle

Answers

Photosynthesis is when plants take in carbon dioxide and create glucose and oxygen. It is apart of the carbon cycle because it removes carbon from the air and turns it into oxygen.

Photosynthesis is the action of plants taking in sunlight to make their food. Just like us humanos make our own food they do the same thing when they get sunlight. This is part of the carbon cycle because during photosynthesis plants absorb sunlight and Carbon dioxide and in the end and let out oxygen.

Summarize cellular respiration and describe how it is part of the carbon cycle.

Answers

During cellular respiration is when a living organism takes in oxygen made from plants during photosynthesis. This is apart of the carbon cycle because it then releases carbon dioxide into the air.

Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. ... Some of the energy is used to make ATP in the mitochondria during cellular respiration, and some is lost to the environment as heat.

1. What is a correct way of naming an organism using the binomial system?
A. Common buttercup
B. ranunculus acris
C. Ranunculus acris
D. Ranunculus sp.

2.When a substance is added to meat, amino acids are produced. What is this substance?
A a hormone
B an enzyme
C an oil
D water

Which group of compounds ensures that metabolic reactions take place effectively?
A carbohydrates
B enzymes
C fatty acids
D hormones

Answers

Answer:

Question 1 :

Ans - C

Explain - Binomial system is made up of Genus (Capital letter) and species (small letter).

# order needs to be correct, Genus

species

Question 2 :

Ans - B

Explain - Meat contain protein where enzymes break down protein into amino acids.

Question 3 :

Ans - B

Explain - Enzyme is a biological catalyst where they speed up chemical reaction.

1. The correct way of naming an organism using the binomial system is Ranunculus acris.

2. When an enzyme is added to meat, amino acids are produced.

3. Enzymes ensures that metabolic reactions take place effectively.

What is binomial system?"Binomial system/nomenclature is the biological system of naming the organisms in which the name is composed of two terms, where, the first term indicates the genus and the second term indicates the species of the organism."The first letter of genus should be in capitals.The species name should be in small letters.What is an enzyme?Enzymes are biological catalyst that increases the rate of metabolic reactions.What are amino acids?"Amino acids are molecules that combine to form proteins."Meat is abundant in protein and when protein digestive enzymes are added it breaks down into its simpler form i.e., amino acids.

Hence the correct answers are: 1. C. Ranunculus acris, 2. B. an enzyme and 3. B. enzymes.

how do fossils give evidence of continental drift? List 2 examples using fossils found on different land masses.

Answers

Answer:

Explanation:

There are many examples of fossils found on separate continents and nowhere else, suggesting the continents were once joined. If Continental Drift had not occurred, the alternative explanations would be:

The species evolved independently on separate continents – contradicting Darwin’s theory of evolution.

Please help, these questions on my hw are confusing to me.

Answers

10. before replication begins, the strands of DNA are separated and used as templates for the new strands. the replication process creates 2 identical double helixes, each has 1 new strand and 1 old one.

11. without dna replication, damaged cells could not be replaced/repaired and cells need dna, cells would become mutated without dna replication.

12. mutations are rare because dna polymerase proofreads the strands but if the process occurred incorrectly and was not corrected by the polymerase, the cell would become mutated and could be really harmful.

hope this helped!

11.) each of the newly replicated helics is formed from a semi-conservative parent strand and one daughter strand

12.) because it creates the next copy of DNA that have to into one of the two daughter cells when a cell divides. Without it each cell lacks enough hereditary fabric to give instructions for crating proteins vital for bodily purposes.

13.) proteins might not function normally or at all. They can cause mutations like disorders or cancer.

Conduction is the transfer of heat between substances with different temperatures. Heat moves from the warmer to the cooler substance through direct contact.

Which feature forms as a result of conduction between magma and water?

di ke
hot spring
caldera
batholith

Answers

Answer:

hot spring

Explanation:

im not entirely sure tbh

Hot springs are formed as a results of conduction of heat between the magma and water. Thus, the correct option is B.

What is Heat conduction?

Heat conduction is the transfer of the internal thermal energy of a system by the collisions of microscopic particles and movement of electrons within a body. The microscopic particles of the body in this heat conduction can be molecules, atoms, and even electrons. Internal energy includes the kinematic and potential energy of the microscopic particles of an object.

Hot springs are formed when the rainwater or the groundwater heats upon by coming in contact with the rocks which have been heated up by the magma, deep beneath the Earth's surface, Hot Spring is formed. This form of geothermal spring generally occurs in the areas near volcanic activities on the planet.

Therefore, the correct option is B.
