Is the result of changes in a population over time due to the process of natural selection.

Biology
1 answer:
Andrews [41]3 years ago

Answer: Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

Explanation: my answer is an explanation in itself

What is the primary function of the carbon cycle
wlad13 [49]

The carbon cycle maintains the balance between the organic remains and carbon dioxide. In this cycle the the incorporation of carbon dioxide inside the plants by photosynthesis occurs and it is returned to the atmosphere by the process of respiration as well as the decaying dead organisms.

01. Bacteria are microscopic organisms present everywhere in our environment. They multiply by binary fission. In order to grow
Marina CMI [18]

Warmth, moisture, pH levels and oxygen levels are the four big physical and chemical factors influencing microbial growth. In most buildings, warmth and moisture are the most significant overall issues current

<h3>How the bacterial growth curve relates to what happens to the bacterial population?</h3>

The bacterial growth curve symbolizes the number of live cells in a bacterial population over a period of time. There are four different phases of the growth curve: lag, exponential (log), stationary, and death. The initial phase is the lag phase where bacteria are metabolically functional but not dividing.

<h3>What are 4 states of bacterial growth?</h3>

Bacteria can live in more burning and colder temperatures than humans, but they do best in a warm, moist, protein-rich atmosphere that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria flourish in extreme heat or cold, while others can stay under highly acidic or extremely salty conditions.

4. A polypeptide has the following amino acid sequence: Met-Ser-Pro-Arg-Leu-Glu-Gly In the mutant below, indicate the type of mu
MatroZZZ [7]

Answer:

4. c. Deletion/ frameshift mutation

5. a. Tyr Tyr Asp Ser Gly

6. A frameshift occurred which altered the identity of the amino acids following the initiator 6. methionine, but not the length of protein Q.

Explanation:

4)

A single base pair at the first position of the Arg codon i.e. CGA has been deleted. Due to the deletion, the reading frame has shifted one nucleotide backwards, altering the amino acid sequence of the protein.

5)

The genomic DNA sequence is 5'-ATG ATA CTA AGG CCC-3'. Therefore, the complementary mRNA will be 5'-UAC UAU GAU UCC GGG-3'. According to the genetic code, this mRNA sequence encodes the following amino acid sequence: Tyr Tyr Asp Ser Gly

6)

The wild type DNA sequence is:

5'-ACUGUAAUGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'

The mutant i.e. mRNA with the added G will be

5' ACUGUAAUGGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'  

This is a single base pair insertion and frameshift mutation that shifts the reading frame one base pair forwards. The codon that was originally GAG coding for glutamic acid (Glu) gets converted to GGA that codes for glycine. Therefore, the amino acid sequence has been altered but the polypeptide chain will still have 13 amino acids.

Light is an example of what in an ecosystem?
BlackZzzverrR [31]


<span>A. abiotic component</span>

An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.
