The data have high precision but poor accuracy because of a systematic error. Thus, the correct option is A.

<h3>What is systematic error?</h3>

An error that is not caused by chance, but rather by a system-wide inaccuracy (in terms of observation or measurement).

The accuracy of a value refers to how close it is to its genuine value. An arrow's proximity to the bull's-eye center is an example. A measurement's precision refers to how repeatable it is. A systematic error has occurred.

Which is an example of population density?
Rudik [331]

Answer:

D: two jaguars per thousand hectares.

Explanation:

Population density refers to the computation of population by unit area. It is usually implemented in living organisms, generally in humans. It is a key geological term. In easy form, population density implies to the number of people existing in an area per square kilometer or hectare, etc.

So, two jaguars per thousand hectares is an example of population density as it involves the number of jaguars (population) per thousand hectares (per unit area).

What modern day practice helps prevent an inadequate production of thyroid hormones?
Mama L [17]

Iodized salts helps to prevent an inadequate production of thyroid hormones .

<h3>What is iodized salts ?</h3>

Iodized salt is a table salt . it is a mixture of very little amount of sodium iodide and potassium iodide .

It helps to prevent iodine deficiency .

It is a micronutrient and dietary mineral that is naturally present in the food supply .and also it is a heavy element .generally found near sea coasts .

Iodine deficiency disease includes hypothyroidism .

<h3>What is hypothyroidism ?</h3>

It occurs due to less secretion of thyroid hormone caused by iodine deficiency .it causes stunted growth . it shows low rate of metabolism .

Hypothyroidism includes diseases like myxoedema or gull's disease , cretinism .

Inadequate supply of iodine in diet causes enlargement of the gland known as simple goitre.

<h3>Thyroid hormones :</h3>

It is secreted by endocrine glands known as thyroid gland . it includes two types of hormones known as thyroxine and calcitonin .

Thyroxine is an iodine containing hormone known as tetra-iodothyroxine(80%) and tri-iodothyroxine (20%).

calcitonin is secreted from thyroid gland and is polypeptide hormone .

Tanzania [10]

Answer:

Photosynthesis produces: <em>glucose </em><em>and </em> O_{2}

                 ...from  CO_{2}, energy (light) and H_{2} O

Respiration produces: energy (ATP),CO_{2}, H_{2} O  

                ....from <em>glucose </em><em>and  </em>O_{2}<em />

<em />

Explanation:

These end products, namely O_{2} and glucose are then used in respiration...

Using energy in the form of solar energy, plants, phytoplankton, algae, and other microorganisms produce chemical energy via photosynthesis. This complex mechanism is central to these species.

They combine light energy from the sun, water, and carbon dioxide.

6CO_{2} + 6H_{2} O + (energy) →C_{6} H_{12} O_{6} + 6O_{2}

In the mechanism of cellular respiration, organisms extract energy from food. Sugars in the form of glucose are broken down into carbon dioxide and water during aerobic respiration in mitochondria to produce energy in the form of ATP (adenosine triphosphate).

<h3>C_{6} H_{12} O_{6} + 6 O_{2}  _{\to \ 6CO_{2} + H_{2} O + energy (ATP)</h3>

The waste products, CO_{2} and H_{2} O,  result from respiration, these are used as reactants in the photosynthetic process. In turn, its products are the reactants O_{2}  and C_{6} H_{12} O_{6} in respiration.
