Answer.

Chemosynthesis is a biological process that takes place in some bacteria and derives energy from the inorganic chemicals, in the absence of solar light. It involves oxidation of inorganic molecules to make organic molecules, such as  glucose.

Chemosynthesis is performed by bacteria that around methane seeps and hydrothermal vents, where sunlight is not present.

Thus, the correct answer is option (A).

During periods of rapid environmental change, what may happen to a species that was well-suited to the former environment?
Hunter-Best [27]

Answer:

The environment usually refers to all the biotic and the abiotic components that are surrounding us. This environment undergoes changes depending upon various factors which can be natural and/or due to the anthropogenic activities.

When there occur rapid environmental changes, then it directly affects the lives of species, in different ways, such as-

  • Those species that are comparatively weaker in adapting according to the environmental changes that occur, will not be able to cope up with the new environment. They may become extinct.
  • Some variety of species will be able to adapt to the new environment because of their easily adapting capabilities.
  • The traits that will be developed within the species in the new environment will be more successful in terms of reproduction.
  • The previously existed traits may have a harmful impact in the newly formed environment.

What is an example of hierarchy representation of information
enyata [817]

Answer:

What is hierarchy? A hierarchy is a way of organizing things that goes from high to low. It can be used to refer to a wide number of systems, organizations and even physical objects that represent a hierarchical structure. Keep reading for hierarchy examples that you see every day.

Everyday Hierarchy Examples

Hierarchy systems rank categories from top to bottom. For example, in a typical family system, the parents have the most authority, followed by the children, then followed by the pets. Take a look around you; you may find more hierarchy examples than you think!

The human body itself is a hierarchy. We are made up of systems of organs, which are made up of individual organs. Those organs are composed of tissues, then cells, then organelles. The final category of a human body hierarchy are the atoms that make up the organelles.

Political systems are hierarchies. In America, the hierarchy starts at the top with the president, and then the vice president, then the speaker of the house, then the president of the Senate, followed by the secretary of state.

Your family tree is a hierarchy starting back with your first ancestors. Their children had children, then those children had children, and so on until your family produced you. You are the child of two distinct genetic parents, and your children will be the next category of this hierarchy.

Human needs are often represented as a hierarchy (such as in Abraham Maslow's Hierarchy of Needs). The most important are your physical needs, such as eating, drinking and sleeping, followed by security. After that is a sense of love and belonging, then confidence and esteem, and finally, self-actualization — the stuff that makes you who you are like creativity, values, acceptance of facts.

The military is a hierarchy. At the very top of the Army, for example, is the authority of the general, followed by the lieutenant-general, followed by the brigadier general, then general, colonel, lieutenant colonel, major, captain, first lieutenant, second lieutenant, master sergeant, sergeant, corporal, then private.

More Examples of Hierarchy Systems

Take a look at even more hierarchy examples that you may already know and use. You'll find that much of science and geography depends on hierarchies as well!

The classification of living things is developed as a hierarchy. Kingdom, phylum, class, order, family, genus, and finally species are the levels of organization in the field, which is known as taxonomy.

Babushka dolls, also known as matryoshka dolls or Russian nesting dolls, are a Russian toy in one large doll holds a smaller doll. That smaller doll holds an even smaller doll, which holds an even smaller doll, and so on. This is known as a nested hierarchy and is used to describe things other than matryoshkas.

Every postal address in our country is a hierarchy with the highest level being the country itself — the United States. After that, the postal address is listed by state, city, street, building, and sometimes the apartment or room number.

Similarly, our political boundaries are hierarchies. It begins with the federal government, then the state government, then city, town, and then borough or municipality, depending on the location.

The workplace is typically a hierarchy. The titles begin with CEO and then descend down the executive ladder to the COO, then to a president, a vice president, a manager, an assistant manager, and then individual employees.

Churches are often hierarchical systems. For example, the Anglican Church has the monarch at the top, followed by the archbishop of canterbury, then the archbishop of york, then the bishops, followed by deaneries, and finally a vicar.

Poker hands are often grouped in hierarchies, with the royal flush as the most valuable hand. It is followed by the straight flush, the 4 of a kind, the full house, the flush, the straight, the 4 of a kind, the 3 of a kind, the 2 pairs, 1 pair, and finally a high card.

If we inserted an anabolic Tryptophan (trp) operon with GFP for amino acid synthesis instead, what would happen if we grew the b
nignag [31]

Answer:

Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.

Explanation:

Understand the following.

The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.

The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.

The dominant allele H reduces the number of body bristles in fruit flies, giving rise to a hairless phenotype. In the homozygous
DerKrebs [107]

Answer:

a. 3:1 (normal bristles to hairless)

b. 2:1 (normal bristles to hairless)

Explanation:

a.  If H allele is present, the fly will be hairless. But H allele is lethal at homozygous condition, so all hairless flies will be heterozygous for H locus (Hh). S allele has no effect on bristle number, but in presence of H allele, S produces a "normal" phenotype and is also lethal at the homozygous condition. So genotypes and phenotypes will be like this:

- SSHH: No viable- Lethal

- SSHh: No viable-Lethal

- SShh: No viable-Lehtal

- SsHH: No viable-Lethal

- SsHh: Normal

- Sshh: Hairless

- ssHH: Normal

- ssHh: Normal

- sshh: Normal  

A cross between two normal flies carrying the two alleles (SsHh) will produce (according to the attached Punnett Square):

6 Normal (SsHh, ssHh, and sshh)

2 Hairless (Sshh)

Therefore, the ratio of flies with normal bristles to hairless individuals will be 3:1.

b. When the hairless progeny of the previous cross (Sshh) are crossed with one of the parental normal flies from part a (SsHh), it will be produced (according to the second Punnett Square):

8 Normal (SsHh, ssHh, and sshh)

4 Hairless (Sshh)

So, the ratio of flies with normal bristles to hairless individuals will be 2:1.
