How do archaea and bacteria differ?​

Biology
1 answer:
Lunna [17]4 years ago
4 0

Answer:

The archaea and the bacteria both are prokaryotes. However, the genetic makeup of the archaea is more similar to the eukaryotes. Moreover, they have differences, in their metabolic pathways, genes and the enzymes possessed by them.

Explanation:

The differences between Archaea and bacteria:

1. The cell wall of the bacteria consist of peptidoglycan, while the cell wall of the archaea consist of pseudo-peptidoglycan.

2. The bacteria are capable of spore formation, which can lie dormant for long periods of time until a suitable condition is found for their growth. The archaea are not known to form such spores.

3. The genes of the archaea are more similar to the eukaryotes than the bacteria.

4. The bacteria are found everywhere where the living conditions are suitable (soil, air, living beings, non-living things). the archaea are capable of surviving in extreme conditions (hot springs, salt brine).

5. The bacteria use the process of glycolysis and follows Kreb's cycle for glucose break-down. The archaea do not undergo glycolysis or Kreb's cycle.

<span>Homeostasis Body's tendency to maintain a steady internal state; physiological equilibrium or balance around an optimal set point. [hot=sweat, cold=shivers] Janice sweating on the treadmill in order for her body to cool off is an example of Homeostasis. Homeostasis is the body's ability to keep a steady internal temperature, state, equilibrium or balance around the ideal set point. This means when you are hot, you sweat to cool the body down and when you are cold your body shivers to help warm it up.</span>

Some species of moose are adapted to eat grasses and flowers in the summer and pine needles in the winter.
Shtirlitz [24]

Answer:

The moose are adapted to live in cold regions where it snows throughout the winter.

Explanation:

These moose have adapted this way because in the winter there is snow on the ground so they do not have access to the grass and flowers they are used to eating. They then adapt to eating pine needles when the ground is covered in snow.

Which DNA fingering technique examines the length variation of DNA repeat sequences in human DNA?
DiKsa [7]

Answer: The question is incorrect, below is the correct question

Which DNA FINGERPRINTING technique examines the length variation of DNA repeat sequences in human DNA?

The correct answer to the question is option D

mtDNA (mitochondrial DNA) analysis

Explanation: DNA fingerprinting technique is a laboratory technique used by geneticists.it entails placing of DNA samples into wells,these wells are then placed in a slab of gels and thereafter passing a current through the gel.This is done to ascertain the uniqueness of a DNA pattern and thus be able to differentiate people of same species.

There are several methods of DNA fingerprinting as outlined in the options given with the question.

In mtDNA (mitochondrial DNA) analysis,The Genetic samples are extracted from the biological materials, these samples extracted are total genomic DNA like hair,tooth or samples of blood, Several copies of these genomic DNA are then produced using a polymerase chain reaction and flanking primers inorder to examines the length variation of DNA repeat sequences in human DNA.

Does personality exist in a social vacuum? That is to say, can we describe individual differences in personality in the abstract
Hoochie [10]

Answer:

Personality can not exist in a social vacuum, thus there aren't any individual differences in personality that exist independently of the social context.

Several authors which have written about personality, relationships and health such as Markey and Markey (2013), states the importance of interactions and relationships to determine personality and its grade of conscientiousness.

Other components of personality in the 5-Factor Model of personality like Extraversion, Agreeableness, among others, examine health and social relationships for understanding disorders of personality.

Nevertheless, a social vacuum is a theoretical construct that can not be studied in reality, therefore there is not a personality that exists in a social vacuum.
