Answer:
C (Chlorophyll)
Explanation:
Adenosine triphosphate (ATP) is an energy carrying molecule in all living cells. It is the usable form of energy by cells. Organisms are able to carry out cellular functions using the energy carried by ATP molecules. ATP like other molecules is made up of components that make up its chemical structure.
ATP is composed of three structural components; A five-carbon sugar called RIBOSE at the core of its structure, attached to a nitrogenous base called Adenine and phosphate group (three in ATP). The energy in ATP is released when it loses its phosphate component.
Chlorophyll is a pigment found in the Chloroplast of plant cells. It is another molecule that is made up of its own components e.g nitrogen, magnesium etc.
Answer: As estrogen and testosterone levels fall in later life, the frequency of intercourse decline or decrease and the frequency of sexual fantasies also decrease or decline.
The sex hormones have an impact and regulate or direct the male and female physical development of the sexual characteristics. The hormones testosterone and estrogen are present both in males and females but the males have higher testosterone levels and females have higher estrogen levels.
In humans the hormones impact the sexual behavior at a lower level once the sufficient level of hormones is present. In the later part of life, with the decline in level of the sex hormones the frequency of intercourse as well as the sexual fantasies decline.
Answer:
1. 1 g/kg body weight
2. 5 g/kg body weight
3. 8 g/kg body weight
4. 10 g/kg body weight
Explanation:
Carbohydrates are one of the most important food groups together with lipids and proteins, and they must be consumed to have a healthy diet. Carbohydrates can be classified into three subtypes: monosaccharides (e.g., sugars), disaccharides (e.g., lactose), and polysaccharides (e.g., starches), which are broken down and absorbed as monosaccharides in the small intestine. These different types of carbohydrates are found in fruits (sugars), milk (lactose), and cereal grains (polysaccharides). Carbohydrate intake in the diets ranges from 6 to 10 g/kg bodyweight depending on the gender and the fitness characteristics of the person, as well as his/her daily energy expenditure. It has been proposed that carbohydrate intake should provide 45–65% of daily calories regardless of age or sex of the individual.
In the spermatheca, females of many insect species, including honeybee queens, can store gametes secreted by their sex partners.
<h3>What is Spermatheca ?</h3>
The female insect's spermatheca is an ectodermal structure that receives, stores, and releases sperm for egg fertilization. According to the species, spermathecae differ in size and shape.
- They often come from the median oviduct, which is located close or on the genital chamber. A secretory duct called the ductus seminalis connects the spermathecal sac, also known as the receptaculum seminis, to the genital chamber, where the sperm are released.
- The number of spermathecas varies among taxa, however the majority of insects only have one. Depending on the species of insect, the spermatheca has different morphologies. The spermatheca is composed of the spermathecal gland, duct, and reservoir. Both of these fluids feed the sperm. Both the spermathecal glands and the male accessory glands secrete substances that feed the sperm.
So lastly we can say that, t females of many insect species, including honeybee queens, can store gametes shed by their mating partners in - the spermatheca.

The answer is meiosis. meiosis is the process that is responsible for the independent assortment of alleles. the role of this process is to separate the chromosomes and it's alleles. thus process is required to produce egg and sperm cell for sexual reproduction.
