Practicing three point shots to improve free throw accuracy contradicts the SPECIFICITY principle of exercise.
The specificity principle of exercise states that, to become an expert in a particular exercise or skill one should perform that exercise or skill. That is, the things that one do during physical activity should be relevant to one desired outcomes, thus, the training regimen must go from general to specific during training.

Deficiencies of carnitine, carnitine acyltransferases, or carnitine/acylcarnitine translocase affect the metabolism of long‑chai

vovikov84 [41]

Answer:

CPT-1 deficiency can cause:

Symptoms of low blood sugar (hypoglycemia)

Liver problems, such as an enlarged organ

Damage to the nervous system, caused by liver (liver) problems

Coma and sudden death

Heart failure

CPT-2 deficiency can affect each person differently, depending on how well the CPT-2 protein is working. Symptoms can be mild to severe. For certain periods, people with this deficiency may not have any symptoms. Very serious forms can affect newborns or babies. These are rarer.

The myopathic form of CPT2 deficiency causes milder symptoms. It does not cause heart or liver problems. People with this form generally have a normal life expectancy. Symptoms can start at any time up to age 60. They can appear if you skip meals, exercise a lot, or get sick. Symptoms may include:

Symptoms of low blood sugar (hypoglycemia)

Temporary muscle pain

Muscle damage

Muscular weakness

Dark urine

So, it can be said that the myopathic form is the least severe and is characterized by recurrent episodes of rhabdomyolysis, muscle pain and weakness triggered by prolonged physical exercise, fasting, viral illness or extreme temperatures. The severe infantile form is characterized by severe intolerance to fasting, leading to metabolic disorders such as hypoketotic hypoglycemia and hepatic encephalopathy. The neonatal lethal form presents with symptoms of the infantile form as well as dysmorphic manifestations (eg, cystic renal dysplasia).

Explanation:

Carnitine palmitoyltransferase (CPT) deficiency is a rare condition that causes muscle weakness and other symptoms. It occurs due to a problem with one or two enzymes, CPT1 or CPT2.

<h2>Lac operon </h2>

Explanation:

Lac operon present in prokaryotic chromosomes whose product involves in transportation and catabolism of lactose

Lac operon consists of three structural genes called Lac Z,Lac Y and Lac A and a regulatory element(promoter and operator)
Lac I gene is present outside the Lac operon,act as regulatory gene and control the expression of Lac operon genes
Lac Z codes for β galactosidase which converts lactose into allolactose
Lac Y codes for Lac permease which act as a membrane transporter and transport lactose into the cells
Lac A codes for transacetylase which neutralize the toxic effects of lactose

Lac operon in absence of lactose

In absence of lactose Lac operon exists in switch off state
Lac I gene produces Lac repressor which binds to operator region and prevent binding of RNA Polymerase thus blocks transcription

Lac operon in presence of lactose

In presence of lactose Lac operon exists in switch on state
In presence of lactose few molecules of Lac operon enzyme catalyse conversion of lactose to allolactose
Allolactose act as an inducer,binds to the Lac repressor and induce conformational changes causing dissociation of Lac repressor from operator
In absence of Lac repressor RNA Polymerase binds to the promoter and starts transcription of genes which catabolize lactose

Lac promoter is a weak promoter and direct transcription of Lac operon genes in very low level in presence of lactose

For higher level expression of Lac operon genes,operon system require conversion of weak promoter to strong promoter which is always mediated by catabolite protein-cAMP complex(CAP-cAMP complex)
CAP cAMP complex binds to the upstream of promoter called CAP binding site and stimulate expression of Lac operon genes by facilitating binding of RNA Polymerase
Catabolite activator protein(CAP) or cAMP receptor protein(CRP) activate when cAMP binds
cAMP is a secondary messenger synthesized from ATP and act as co-activator of CRP
With respect to CAP cAMP complex Lac operon system is positively controlled
In prokaryotic cell cAMP is very low when glucose concentration is relatively high and vice versa
At high concentration of glucose the growth rate is maximum and lactose catabolism is repressed called catabolite repression

Which of these is NOT something found in the fossil record that has been used by scientists to understand human evolutionary pat

Makovka662 [10]

Answer:

The correct answer is option (d)-"All of these are found in the fossil record and have been used by scientists to understand human evolution".

Explanation:

There is plenty of evidence that supports the proposal of how humans has evolved during past times. The fossil records that scientists has used understand human evolutionary patterns include the following. Ardipithecus ramidus bones that revealed advances in upright walking, even tough they had a small brain that measured between 300 and 350 cm3. Australopithecus lack of an opposable big toe suggest that they lived on the ground instead of in trees. Homo erectus was the first species to use and control fire, as suggested by evidence of microscopic traces of wood ash.
