¿Qué importancia tiene el agua en las reacciones químicas?

Answers

Answer 1

Answer:

El agua es un medio ideal para reacciones químicas, ya que puede almacenar una gran cantidad de calor, es eléctricamente neutral y tiene un pH de 7.0, lo que significa es que no es ácida ni básica. Además, el agua participa en muchas reacciones enzimáticas como agente para romper enlaces o, al eliminar de una molécula, para formar enlaces.

A true reversion occurs when the wild-type DNA sequence is restored to encode its original message by a second mutation at the same site or within the same codon. Which of the following isoleucine codon(s) could be mutated once to form a methionine codon, and then mutated at a second site to restore an isoleucine codon?
A. AUC.
B. AUU.
C. AUA.
D. None of these codons.

Answers

Answer:

The correct answer is option d- none of these.

Explanation:

The genetic code for methionne is AUG and genetic code for isoleucine are AUC, AUA, AUU. As we can see that there are first two codons are similar for both methionine and isoleucine.

So mutation at to any other site other than third psostion not possible that can convert isoleucine to methionine and this same mutation site is the only mutation position mutation can revere back methionine to isoleucine.

Thus, none of the given can restore an isoleucine codon.

When an organism encounters nitrate in its environment, which condition will determine whether the nitrate is used in an assimilatory or dissimilatory manner?

a. low concentration or ammonia
b. low concentration of sulfate
c. oxygen present
d. low temperature
e. oxygen absent
f. high concentration of nitrite

Answers

Answer:

Dissimilatory- oxygen absent

Assimilatory- high concentration of nitrite

Explanation:

In assimilatory nitrate reduction, ammonium is produced and subsequently incorporated into biomass to build up e.g., proteins and nucleic acids. Dissimilatory nitrate reduction is a process for energy conservation, in which nitrate is used as an electron acceptor in the (near) absence of oxygen . Dissimilatory nitrate reduction and nitrate storage in particular are physiological life traits that provide microbes with environmental flexibility (i.e., metabolic activity under both oxic and anoxic conditions) and resource independence (i.e., anaerobic metabolism without immediate nitrate supply), respectively. Such life traits are especially important in environments that are temporarily anoxic and/or nitrate-free and they may have developed as a “life strategy” in both prokaryotes and eukaryotes

assertion: empty milk pouches are biodegradable Reason: they cannot be used in biogas formation​

Answers

Answer:

The pollutants like heavy metals, organic solvents present in pesticides exist in small amounts in the atmosphere. During the process of the food chain, the concentration of these pollutants progressively keeps on increasing through different trophic levels. For example, fish eats a lot of planktonic growth may retain the pollutants in their tissues, birds or people that eat the fish might concentrate the pollutants still more. This process of accumulation of pollutants at different trophic levels is called as biomagnification. So, the correct answer is 'Assertion is correct but Reason is incorrect'.

perform photosynthesis

Answers

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.

Conifer Leaf.  

Microphyll Leaf.  

Megaphyll Leaf.

A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.

The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

For the following three cultures, using any resource find out if they are obligate aerobes, facultative anaerobe, or obligate anaerobe- o Escherichia coli o Micrococcus luteus o Clostridium sporogenes

Answers

Answer:

Escherichia coli - Facultative anaerobe

Micrococcus luteus - Obligate aerobe

Clostridium sporogenes - Obligate anaerobe

Explanation:

In simple terms, obligate aerobes are organisms that require oxygen to grow and metabolize molecules such as fats and sugars to produce energy. Many animals fall under this category. Other examples are Mycobacterium tuberculosis and Micrococcus luteus.

Facultative anaerobes are organisms (usually bacteria) that can grow both in the presence and absence of oxygen. The most example of this are the Escherichia coli.

Obligate anaerobes are organisms (usually microorganisms) that cannot survive when exposed to normal atmospheric concentration of oxygen. Examples are Clostridium sporogenes and Clostridium botulinum.

Which of the following requires constant agonist-antagonist muscle contractions?
Core integration
Postural development
Dynamic balance
Neuromuscular strength

Answers

Answer:

Postural development

Explanation:

The agonist muscles are sets of muscles responsible for causing joint motion, whereas antagonist muscles are muscles that directly opposite agonist muscles (i.e., antagonist muscles generate an opposing joint torque to the agonist muscles). In a given movement, agonist muscles exhibit concentric contractions while antagonist muscles show eccentric contractions in order to stabilize the joint. Postural development is achieved by concerted adjustments of dorsal muscles and ventral muscles. The dorsal muscles are activated when the body sways forward and the muscle fascicles shorten. During backward sway, these muscles lengthen, while ventral muscles are primarily activated.

Dynamic balance is the condition that requires constant agonist-antagonist muscle contractions.

The agonist-antagonist muscle contraction is the movement where one muscle contracts while the other muscle is relaxing or lengthening. The muscle contracts are agonist whereas the muscle that relaxes is the antagonist here.

Core integration: In such conditions, the constant movement of muscle contraction and relaxation does not require. It is a specific movement and increased stability of the movements.Postural development: continuous development and growth of postural muscles comprising the nervous systemDynamic balance: It would be the ability to balance in motion or changing positions. In this case, muscles require constant both agonist and antagonist contractionsNeuromuscular strength: motor commands according to the central nervous system to the ability to move in the nervous system, hence it does not require constant muscle movements.

Thus, the correct answer is - Dynamic balance.
