Earths inner core:__as earth's outer crust:liquid

Dahasolnce [82]

Answer:

The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly composed of basalt. The inner core is made from Iron and Nickel.

In a biological reaction, succinate dehydrogenase catalyzes the conversion of succinate to fumarate. The reaction is inhibited b

Rama09 [41]

Answer:

a. It is a competitive inhibitor.

Explanation:

A competitive inhibitor competes with the substrate for the active site of the enzyme. Binding of the competitive inhibitor to the active site of enzyme forms enzyme-inhibitor complex and does not allow the substrate to bind to the enzyme. This inhibits the reaction. However, the competitive inhibition is overcome by increasing the concentration of substrate around the enzyme to facilitate its binding to the enzyme's active site.

According to the given information, malonic acid competes with succinate for the active site of enzyme succinate dehydrogenase and inhibits the reaction. This inhibition is overcome by increasing the succinate concentration around the enzyme. This makes malonic acid a competitive inhibitor to succinate dehydrogenase.

After people have been drinking: ✗

mario62 [17]

For the first Question: The right answer is only A.

After people have drunk, it will be harder for them to make quick decisions, as is the case in driving, since motor coordination and judgment are impaired,

It can take up to two hours or more to get rid of the alcohol (it depends on the ethnicity of the person and whether it is a regular drinker or not), so it would take a lot more than an hour to get rid of alcohol in the body.

For the second question: the right answer is All above

According to the National Institute on Alcohol Abuse and Alcoholism in the USA, one standard drink contains approximately 14 grams of pure alcohol, which represents the measures mentioned in the MCQ.

For the third question:

When the victim has just absorbed too much toxic, he initially has troubles of consciousness and a ventilatory stop that can change, in the absence of first aid, to death.

As soon as you discover this toxic abuse, call the SAMU (15) and do the first aid:

In case of disturbances of consciousness, carefully tilt your head backward.

Check for the presence of breathing movements, and place the casualty in the lateral safety position.

In the presence of respiratory arrest, after having checked the presence of a carotid pulse, practice mouth-to-mouth.

In all cases, surveillance of the victim is mandatory until the arrival of medical aid.

The trait for medium-sized leaves in iris is determined by the genetic condition PP'. Plants with large leaves are PP, whereas p

loris [4]

Answer:

See the answer below

Explanation:

Medium size leaves genotype = PP'

Large leaves genotype = PP

Small leaves genotype = P'P'

Red flower genotype = RR

Pink flower genotype = RR'

White flower genotype = R'R'

Two plants each with medium-sized leaves (PP') and pink flowers (RR') were crossed.

PP'RR' x PP'RR' (let PP' = Aa and RR' = Bb)

Progeny and expected phenotypes

1 PPRR - large leaves, red flower = 1/16 x 640 = 40 seedlings

2 PPRR' - large leaves, pink flower = 2/16 x 640 = 80 seedlings

2 PP'RR - medium leaves, red flower = 2/16 x 640 = 80 seedlings

4 PP'RR' - medium leaves, pink flower = 4/16 x 640 = 160 seedlings

1 PPR'R' - large leaves, white flower = 1/16 x 640 = 40 seedlings

2 PP'R'R' - medium leaves, white flower = 2/16 x 640 = 80 seedlings

1 P'P'RR - small leaves, red flower = 1/16 x 640 = 40 seedlings

2 P'P'RR' - small leaves, pink flower = 2/16 x 640 = 80 seedlings

1 P'P'R'R' = small leaves, white flower = 1/16 x 640 = 40 seedlings
