Which of the following is true about the role of genetic and environmental factors in human health?
A) Genes are the only factor affecting whether or not an idividual will contract a disease.
B) Genetic factors are more important than environmental factors in determining an individual's
personal health risks.
C) Individuals can influence their health by controlling their genetic traits.
D) Environmental factors determine whether or not all genetic traits lead to health issues.
E) Certain environments can lead to an increased risk of developing certain diseases.
Answer: E) Certain environments can lead to an increased risk of developing certain diseases.
Explanation: This is the most logical answer since environmental factors, such as pollution, can increase one's risk of developing certain diseases.
A. is incorrect because genetic factors are not the only things that affect individual health. One's environment also factors in. If one lives a healthy lifestyle, they can help prevent themselves from developing disease that are more "encouraged" by their genes. An example would be a genetic trait that increases one's risk for heart disease. One can work to avoid heart disease by utilizing a healthier lifestyle.
B. is wrong because environmental factors play an equal role in determining if one will develop some genetically linked diseases.
C. is incorrect because as it stands, one cannot control their genetic traits.
D. is incorrect because some diseases, such as cystic fibrosis and sickle cell anemia are genetically inherited diseases which cannot be prevented by environmental factors. This is not to say that environmental factors are independent of all genetically linked diseases, but not all diseases can be prevented by environmental factors.

consider a cross between two individuals whose genotypes for two different loci are AaBb and AaBb. predict the outcomes of this cross. from the options below. select all that are possible from this cross
Answer:
It’s A,B,E!!
Explanation:
I just did it on USATestPrep!!
In dihybrid cross due to independent assortment if the cross between genotypes for two different loci is AaBb and AaBb, the outcomes are 1/16 progeny will be AABB and 1/16 is aabb, and 1/4 offspring will be AaBb like parents, hence option a,b,e is correct.
What is a dihybrid cross?In 1865, Gregor Mendel performed dihybrid crosses on pea plants and found the Property of Independent Assortment, a basic law of genetics.
He developed the dihybrid cross based on the same rules as a monohybrid cross. He determined the phenotypic ratio (9:3:3:1) seen in a dihybrid cross for a heterozygous cross from these investigations.
The Cross between AaBb and AaBb is shown in punnet square in the diagram below, and the outcomes are 1/16 progeny will be AABB and 1/16 is aabb, and 1/4 offspring will be AaBb.
Therefore due to independent assortment in the dihybrid cross, options a,b, and e is correct.

Explain a wedge and give 3 examples.
Answer: A wedge is basically an incline plane. Often portable used for many purposes
Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.
In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.
The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.
The wedge works on the principle of an inclined plane.

Hope this helps Have a awesome day❤️do all plants make the same kind of sugar? true or false
Answer:
same sugar different concentrations so yes true.
Explanation:
Technically they all make gluclose but different plants produce different amounts of it.
Yes, this statement is true.
Plants make same kind of sugar but the concentration of sugar is different.
All green plants produce sugars through photosynthesis, a natural process that turns sunlight into energy.Different parts of plants have different concentrations of sugars. These different concentrations form what are called concentration gradients. To move sugars to some areas or cells, up concentration gradients, plants need to use proton pumps, many which require phosphorus and other enzymes.Thus, the statement is true.

In 2006, an Ethiopian researcher announced the discovery of well-preserved 3.3 million-year-old fossil of a young female hominid. Refer to Figure (F) below. Considering the Hominid trend of evolution, choose which skull would most likely be that most primitive of the three.
Answer:
Skull three
Explanation:
the backlining is in more, and the jaw moves out more, resembeling that of a more gorilla like creature
It sounds like the description is referring to a hominid with a more pronounced facial structure, similar to that of a gorilla. This may indicate a more primitive stage of hominid evolution, as earlier hominids had more pronounced facial features and a more protruding jaw than later, more advanced hominids.
What is the basic evolutionary changes in the group mentioned ?As hominids evolved over time, their facial features became more refined, and their jaw became less protruding as they adapted to a diet that relied less on tough, fibrous vegetation and more on softer, cooked foods. This adaptation allowed for the development of a larger braincase and a more upright posture, both of which are hallmarks of later hominids such as Homo erectus and Homo sapiens.
It's worth noting that the evolution of hominids is a complex and ongoing area of research, and new discoveries and interpretations of existing evidence may change our understanding of the evolutionary timeline and the characteristics of different hominid species.
Over the course of hominid evolution, several important changes occurred that distinguish hominids from other primates. One of the earliest changes was the development of bipedalism, or the ability to walk on two legs. Bipedalism allowed hominids to free their hands for tool use and other tasks, and also facilitated the long-distance travel needed to explore new environments.
