Having a platelet count of 60,000/mirol is below the normal count of 150,000 which is called thrombocytopenia. With this low platelet count, our skin which is part of the integumentary system will show signs of Petechiae. Petechiae are formed and seen on the skin when capillaries underneath leaks blood due to low platelet count. Petechiae is commonly found on a person suffering from Dengue Hemorrhagic fever Disease where platelet count decreases.
The changes that occur during puberty are mostly a result of changes in hormone levels in the body.
<h3>Puberty</h3>
The transition from a child to an adult is caused by changes in the level of some hormones in the body.
In females, there is an increase in follicle-stimulating hormones as well as luteinizing hormones, leading to an increase in the production of progesterone.
In males, there is an increase in the production of testosterone hormone among many other hormones.
Both progesterone and testosterone are responsible for the development of physical features in females and males respectively.

Answer:
Independent variable: different amounts of second-hand smoke
Explanation:
The independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response.
In this question, a test is being carried out to determine the health effects of different amounts of second-hand smoke on one-year-old hamsters. Based on this, the independent/manipulated variable is the DIFFERENT AMOUNTS OF SECOND-HAND SMOKE because it is the variable being changed.
Many organisms that undergo chemosynthesis use ________ instead of ________ to fuel the processes that convert carbon dioxide into sugars.
a. energy; sunlight
b. hydrogen sulfide (H2S); sunlight
c. sunlight; water
d. sunlight; carbohydrates
e. sunlight; sulfuric acid
Answer:
b. hydrogen sulfide (H2S); sunlight
Explanation:
Some autotrophic organisms do not use the energy of sunlight to fix the inorganic simpler substances such as CO2 into the organic sugars. These organisms perform oxidation of chemical compounds. The energy released from the oxidation of organic or inorganic chemicals is used to fix CO2 into sugars. These organisms are called chemotrophs. Some chemotrophs such as sulfur-oxidizing bacteria use H2S as a source of energy to fix CO2.
Xerostomia
The medical term for this condition is xerostomia. Xerostomia
refers to abnormal dryness of the mouth which may be caused by a reduction in
the volume of saliva. Saliva is an important fluid in the body that assists to
protect and maintain oral health.
