Can a gene mutation that does not influence phenotype be considered an adaptation? Why or why not?
Answer:
No; only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.

Many Learners Perform Well In Grade 12 But still not accepted into Universities.Explain Two Reasons For This
Answer:
1. Confusion
2. Financial issue
Explanation:
1. The reason I say this is that many of them are not really sure about what they want they want to do in their later future making them a little confused on what to do.
2. It is a common issue which has taken away so many bright minds away from their future in helping the world and their individual community to prosper in different ways.
The reason why many students from grade 12 are not accepted in universities is that they may not be ready to pursue a given career or their parents may not be able to afford it.
Why are grade 12 students not accepted in universities?In the whole of North America, grade 12 is the senior class or the highest class in high school.
Some grade 12 students may not be admitted into university even though they performed well because;
Some of the students who have finished well in grade 12 do not yet have clear cut career orientations.Also, some of them may not have parents that can afford to send them to the university.Hence, a good performance in grade 12 do not guarantee university admission.

Which option lists materials in order by their ability to allow the flow of
electrons, from least easily to most easily?
A. Insulator, semiconductor, conductor
B. Conductor, semiconductor, insulator
c. Semiconductor, insulator, conductor
O D. Semiconductor, conductor, insulator
The correct option that lists materials in order by their ability to allow the flow of electrons, from least easily to most easily, is Insulator, Semiconductor, and Conductor, which is in Option A.
What are an electron, an insulator, etc.?The ability of a material to conduct electricity depends on the number of free electrons that are available to move through the material. In an insulator, there are very few free electrons, which means that the material does not conduct electricity very well. Insulators are typically used to prevent the flow of electricity, for example, in electrical wiring, where plastic or rubber coatings are used to insulate the copper wires.
Hence, the correct option that lists materials in order by their ability to allow the flow of electrons, from least easily to most easily, is Insulator, Semiconductor, and Conductor, which is in Option A.

What are your top 3 favorite lifeforms and why? What adaptations help these living things to survive in their environment?
please help
I will give brainliest for the best answer
Answer:
so it's saying what are your favorite animals or plants or living things and how do they survive
hi!! here's ur answer!!
my top 3 favourite lifeforms are- polar bears,tigers and ducks. :D
1) polar bears- are well adapted for survival in the Arctic. Their adaptations include: a white appearance - as camouflage from prey on the snow and ice. thick layers of fat and fur - for insulation against the cold.
2) tigers- striped coat helps them blend in well with the sunlight filtering through the treetops to the jungle floor. The tiger's seamless camouflage to their surroundings is enhanced because the striping also helps break up their body shape, making them difficult to detect for unsuspecting prey.
3) ducks- possess an oily coating that keeps water from settling in their feathers, helping them in staying dry and keeping themselves warm. Their webbed feet, designed like paddles, provide more surface area to push against the water and help them swim.
hope it helps:)
Explore the three different types of ground tissue cells in detail and complete the chart below.
Answer:
parenchyma have primary cell walls (thin) and are unspecialized and metabolically active (photosynthesis, respiration)
collenchyma have primary cell walls (unevenly thick) which provide a level of structural support in areas of high growth, they are alive so have a protoplast
sclerenchyma have secondary cell walls which means they have lignin and are thick, they are functionally dead at maturity so provide support in areas that are done growing and are involved in transport of water
