identify the explanations researchers suggested to explain differences in health and mortality by gender.
The differences in health and mortality by gender is a phenomenon for which researchers have many possible explanations.
There have been studies that have indicated that there is enough variation in the average health of males and females to conclude that there are factors at play that are affecting health.
Amongst the many possibilities, scientists have mentioned:
Gender-reliant genetic vulnerability Hormonal factorsDifferences in physiologyas the main possible reasons.
Hormones play a big part in the health of each individual and are vastly different between genders, along with the endless differences in physiology at a molecular level. These factors together may explain why some members of a gender are more vulnerable to genetic illness.

An irrigation system is a structure made of tubes, hoses, and sprinkles; Its function is to water plants or crops with the correct amount of water and in an evenly way.
A simple irrigation system that will help grow plants at home is a plastic bottle with small holes connected to a hose with a tube that can lead the water from the hose to the bottle without losses. The bottle with its holes works as a sprinkler.
In conclusion, irrigation systems are in lawns, fields, or gardens, and they water the plants evenly so that they can grow. There are many types, but we can build a simple one with a bottle.

In camellia plants, flower color is controlled by a single gene with codominant alleles. A camellia plants with red flowers (RR) is crossed with a camellia plant with white flowers (WW). What are the expected phenotypes of the offspring of this cross?
Answer:
All will have both red and white flowers because the incomplete dominance have two combined alleles given for the offspring with intermediate phenotypes. Then offspring will be pink coloured while in codominance all alleles are expressed in phenotype in the offspring together so the red and white flowers both will be shown.

why is the digestive tract of the frog well vascularized
The digestive tract of the frog is well vascularized because it aids in the absorption of nutrients.
The digestive tract of a frog is a hollow long tube that extends from the mouth to the anus which helps in the ingestion and digestion of food.
The digestive tract of frog has the following characteristics:
alimentary canal of the frog is not long, that is, it is short. It has accessory organs of digestion such as liver, gall bladder and pancreas.All the digested food substances are absorbed at the small intestine due to the presence of microvilli.
This microvilli is made up of a central core that is vascularized, that is, it contains artery, vein and lymphatic capillary.
Therefore, the vascularized microvilli of the small intestine of frog help in the absorption of nutrients.

Question 1 options:
Decreasing energy
Stored energy
Elastic
Movement
Answer:
elastic
Explanation:
The kinetic energy of a body can be decreased in two cases: When it is stored in the form of potential, for example: elastic or gravitational energy. Or when there are dissipative forces capable of transforming it into other forms of energy, as does the friction force. Which transforms kinetic energy into thermal energy.
