How deep are cactus roots

2 answers:

Roots. Many cacti have roots that spread out widely, but only penetrate a short distance into the soil. In one case, a young saguaro only 12 cm (4.7 in) tall had a root system with a diameter of 2 m (7 ft), but no more than 10 cm (4 in) deep.

Hope This Helps! :-)

In other words they can't penetrate that deep.

How are the terms nucleotide, nitrogenous base, and nucleic acid related to each other?

hoa [83]

A nucleic acid is made of nucleotides, and nitrogenous bases are a part of a nucleotide.

DNA is a nucleic acid. The nucleotides in DNA are made up of a sugar (deoxyribose), a phosphate group, and one nitrogenous base (which will be either adenine, guanine, cytosine, or thymine).

Hope this helps!!

Answer:

F1: Aa Bb Cc: 4.5 lbs

F2: Too many to list: Between 3 lbs and 6 lbs

Explanation:

F1: Aa Bb Cc, will be the genotypes and will weigh 4.5 lbs, the reason for that is because each capital letter allele adds half a pound to the base weight of 3 lbs.

F2: There are many different genotypes that can be present in the second generation, for example (AA BB CC, AA BB Cc, AA BB cc, etc.) each of which will allow the plant to grow to a certain height. The majority of phenotypes will be 4.5 lbs. There will be one who is AA BB CC, and another one person who has the code, aa bb cc.

Mrrafil [7]

Answer:

The correct answer would be B. semi-permeable.

Plasma membrane of any cell including red blood cell is semi-permeable in nature as it is made up of lipid bilayer.

It permits the passage of certain substances across the membrane while it blocks other substances.

Gases, small uncharged or non-polar substances such as oxygen, carbon dioxide, et cetera can easily pass through the cell membrane of a cell.

Large or charged molecules such as proteins, sodium ions, potassium ions et cetera can not pass through the cell membrane. They require carrier proteins to pass through the membrane.
