The Australian giant burrowing cockroach (Macropanesthia rhinoceros) is the heaviest cockroach in the world. You are the leading expert on the genetics of this species and are working to domesticate them for food production. Your starting population (G0) has a mean body mass of 30 g and variance of 0.674 g2. You select the largest roaches from this population to breed the next generation (G1). The selected breeders have a mean body mass of 32.4 g and a variance of 0.215 g2. If the narrow sense heritability (h2) of body mass in your cockroaches is 0.35, what will be the expected mean body mass of the G1 population? Round your answer to 2 decimal places.
For an Australian giant burrowing cockroach is the heaviest cockroach in the world, the expected mean is mathematically given as
M= 31.56g
What will be the expected mean body mass of the G1 population?
Generally, the equation for the Narrow sense heritability is mathematically given as
h^2=R/S
Where
S= Selection differential
R= Selection response
R = M-30
S = (32.4-30)
S= 2.4g
In conclusion
(h^2) = R/S
h^2= 0.65
h^2= (M-30)/2.4
Hence
M = (30+1.56)
M= 31.56g

How do fossils help the support the theory of evolution
Answer:
Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils.

Plants may control the quantity of water and solutes they contain by using guard cells, which use osmotic pressure to open and close stomata. Thus, option A is correct.
What is the major function of guard cell in photosynthesis?Guard cells adjust the efficiency of leaf gas exchange in response to shifting environmental factors, and changes in atmospheric CO2 concentration, light intensity, humidity, and the drought hormone abscisic acid regulate their turgor.
Stomata, which are pores in the plant epidermis, serve as passageways connecting the intercellular gas spaces to the outside world.
Each stomatal hole is surrounded by two guard cells, and variations in the turgor pressure of the guard cells control the pore aperture size.
Therefore, it allows the intake of gases necessary for photosynthesis.

Why were Mendel's experiments important to biology?
Select all that apply.
they showed that all traits are either dominant or recessive
they showed that DNA contains the genes that control traits
they showed that inheritance was a random process
they showed that mathematical models could be used to explain inheritance
Answer:
a
Explanation:
During mendel's pea plant experiment he discovered recessive and dominant traits.
They showed that all traits are either dominant or recessive, They showed that inheritance was a random process. They showed that mathematical models could be used to explain inheritance.
What is inheritance?Inheritance is the process by which genetic information is passed down from one generation to the next.
Mendel's experiments with pea plants in the mid-1800s helped to establish the field of genetics and provided a foundation for understanding how traits are passed down from generation to generation.
Through his careful observations and experiments, Mendel was able to identify several key principles of inheritance, including the concept of dominant and recessive traits, the inheritance of traits independently of one another, and the random assortment of alleles during the formation of gametes
Thus, these findings were significant because they challenged prevailing ideas about inheritance at the time and provided a basis for further research into the molecular basis of genetics.

During the day, an area of high / low air pressure forms over water and a sea / land breeze occurs
Answer:
Explanation:
The specific heat of water is more than that of sand, thus air above land becomes hot quickly and rises up. The cold air above water then move towards land. This is called sea breeze.
A high air pressure area forms on the water during the day, resulting in the sea breeze. The sea breeze is when the wind flows from the sea towards the land during the day.
What is a sea breeze?
During this time, the earth receives sunlight, which raises the temperature of the atmosphere. Between the sea and the land, the land gets hotter in less time than the water by the sun's light, and this is because the water has a high heat capacity.
The water needs a lot of energy to raise the temperature, and this is due to the water's high specific heat, but in comparison to water, the land has a low specific heat, so it gets warmer quickly. As a result, the air present on the land gets lighter and goes up. As a result, cooler air flows from the sea to the land, causing the sea breeze.
As a result, during the day, a high air pressure area forms over the water, resulting in a sea breeze.
