Why are the four macro molecules important?

Biology
1 answer:
adell [148]3 years ago
4 0

These molecules - proteins, lipids, carbohydrates, and nucleic acids - make up every component in living things. Lipids are used as energy and form making membranes that all living things have. Carbohydrates are the primary source of energy for many living things. Proteins are used to build tissues or enzymes. Nucleic acids are used for the genetic material to be transferred to offspring.

Answer:

Explanation:

1. Which chamber receives blood from all the body veins?

= Right atrium

2. The blood passes from this chamber into the ...

= Right ventricle

While this is happening, the valve between the right atrium and right ventricle is (open OR closed)

= open

3. The blood in the right ventricle is high in (oxygen OR carbon dioxide)

= carbon dioxide

4. The body (can OR cannot) and low in (oxygen OR carbon dioxide) use this blood.

= cannot

= oxygen

5. Where must this blood go to get a fresh supply of oxygen?

= lungs

Hope this helps!

What must occur for protein translation to begin?
Ronch [10]

The correct answer is D) The codon AUG must be identified.

What must occur for protein translation to begin is that the codon AUG must be identified.

The process starts when the 5AUG or start codon is identified. In the polypeptide chain, the 5AUG is the first amino acid. We are talking about Transition, the process when the genetic code in an RNA molecule has to be decoded in a polypeptide chain in order to deliver an amino acid sequence. In this complex transition system, there are important components included such as ribosomes, transfer RNA, and mRNA.

A species of oak tree grows in deciduous, hardwood forests. This species grows and germinates in close proximity to one another
kifflom [539]

Answer:

clustered distribution (clumped)

Explanation:

In ecology, species distribution refers to the way in which a biological taxon is spatially arranged in a particular geographic area. Species patterns of distribution are fundamental to analyze ecological systems. The main distribution patterns include 1-clustered (clumped) distribution, 2-uniformed distribution, and 3-randomized distribution. The clustered distribution is the most common type of dispersion pattern in nature and occurs when species tend to form small sets of three or more individuals clustered together. A clustered distribution may be due, for example, when resources (e.g., water) are not evenly distributed in the environment (unequal distribution of the resources). Moreover, a uniform distribution occurs organisms keep a uniform, constant, distance from each other (e.g., due to competition for limited resources), while a randomized distribution occurs when individuals are randomly distributed because resources are not limited.

The polymerase chain reaction (PCR) is used to generate: multiple copies of a targeted region of DNA. a single copy of a targete
Naddik [55]

Answer: multiple copies of a targeted region of DNA.

Explanation: Polymerase chain reaction is a technique used in molecular biology to produce millions of copies of specific DNA segment. This involves taking a minute sample of DNA segment and hugely amplifying it to produce multiple copies of the segment. PCR procedure has three step:

1). Heating the double stranded DNA containing the targeted DNA region to be amplified in order to separate the strands.

2). Allowing the strands to cool and adding synthetic oligonucleotide primers.

3). Addition of thermostats DNA polymerase to catalyze 5'->3' DNA synthesis.

The process is repeated in about 25 to 30 cycles and the amplified DNA can be cloned.

PCR was invented in 1983 by Kary Mullis.
