One redo our could be a body of water like a dam as such, and another is something like a retention pond, taking in water
Answer:
The correct answer is Option B (Carrying out research). The step that follows this step involves forming B.a conclusion
Explanation:
The Natural environment around us is a function of both the living things and the non-living things. So, environmental science is the study of the natural environment around us. This study includes how to tackle environmental problems and further study on how humans could be impacted by the interactions with their environment. The scientific method is a step taken towards ensuring development in a field by bringing new discoveries and challenging existing beliefs through scientific tests and research. Generally, for most scientific methods of many fields, it starts with:
1. Observations
2. Making inquiry which involves asking questions
3. Forming a hypothesis, which means making untested assumptions
4. Conducting an experiment to check the hypothesis
5. Analyze the results
6. Publish the results
The correct answer is Option B (Carrying out research). Because it involves the scientific method highlighted above. The step that follows this step involves forming B.a conclusion
Answer:
A fertilized zygote created through meiosis and sexual reproduction has a combination of genetic material
Answer:
17
Explanation:
In corn,
Smooth kernel (S) is dominant to rough kernel (s)
Purple kernel (P) is dominant to yellow kernel (p)
Since no information has been given about the cross here let us assume it to be a standard dihybrid cross.
The phenotypic ratio of dihybrid cross is 9:3:3:1. 9/16 will show dominant phenotype for both traits, 3/16 will show dominant phenotype for one trait, other 3/16 will show dominant phenotype for the second trait, 1/16 will have recessive phenotype for both the traits.
Here,
Purple rough (P_ss) = 52
Yellow smooth (ppS_) = 50
Both of them show dominant phenotype for one trait so they each form 3/16 of the progeny.
If the total progeny was z, 3/16*z = 50
z = (50*16)/3 = 267
Total progeny = 267 kernels
Yellow rough kernels (ppss) = (1/16*267) = 17
So approximately 17 corn kernels will be yellow and rough.
