Using the human species as an example, explain what is meant by a variation of traits.
Explanation:
a variation of traits could be a variation of personality traits? everybody is different? what I do know Is that variation can be inherited or environmental which means that you get it from your ancestors through DNA or you get it from the environment around you and your choices eg a tattoo
Several genes in humans in addition to the ABO gene (I) give rise to recognizable antigens on the surface of the red blood cells. The Rh marker is determined by positive (R) and negative alleles (r) of gene R, where R is completely dominant to r. The presence of M and N surface markers are controlled by two codominant alleles of gene L (LM and LN). For each mother-child pair, choose the father of the child from among the males in the right column. (Assume that all mothers and fathers are HH.)

Imagine yourself as a naturalist. In your travels, you observe the toad and frog
shown here. Write two questions that might arise from these observations.
Answer:
1. What is the relationship between body shape and the habitat where they are most commonly found?
2. What is the difference between toads having a thicker skin than frogs?
Explanation:
Toads and frogs are amphibians that belong to the same family, live in lakes, rivers and wetlands and have some similar characteristics. Among their main differences are:
The skin of toads is rougher, drier and rougher. While frog skin is moist and smooth. Frogs live in humid areas, although they can go out to dry land for food. Whereas toads can survive longer on the ground away from moisture, as they have greater water control in the body. Frogs are characterized by long limbs that favor long hopping and swimming. On the other hand, toads have shorter legs. Toads tend to be more rounded, muscular and stocky. Frogs tend to be more slender.Most toads are poisonous. In contrast in frogs, not all species are poisonous.
Given these observations, two questions that may arise could be:
1. What is the relationship between body shape and the habitat where they are most commonly found? This is that frogs have longer legs which helps them to swim and that is why they are more commonly found in water. While toads have shorter legs that even allow them to burrow into the ground, they can survive longer on land.
2. What is the difference between toads having a thicker skin than frogs? Toads have thicker and more impermeable skin than frogs, which allows them to live in drier places. Also, the blood of the toad is of higher osmotic concentration than water.
Answer: what is the difference between the body’s and the habitat they are in?
Explanation:both have similar habitats and look the same

What are the possible results of breeding a dark brown mouse with a light brown mouse?
Can two species share the same niche? Why or why not?
Answer:
No
Explanation:
Because they'd be fighting for the exact same resources
Answer:
The competitive exclusion principle tells us that two species can't have exactly the same niche in a habitat and stably coexist. That's because species with identical niches also have identical needs, which means they would compete for precisely the same resources.

After chemical weathering, what happens to the chemical makeup of the weathered rock?
-The rock stays the same
-The rock gets larger.
-The rock changes form.
-The rock disappears.
Answer:
rock changes its form
Explanation:
Hope was helpful
If yes than plz ❤️
After chemical weathering, the rock changes form. Therefore, option C is correct.
What are weathering and its types?The breakdown or dissolution of rocks and minerals on the surface of the Earth is known as weathering. Once a rock has been disintegrated, the minerals and rock fragments are carried away by a process known as erosion. Weathering and erosion can be caused by water, acids, salt, plants, animals, and temperature changes.
Because it contributes to the formation of numerous different types of landforms on the surface of the earth, weathering is a crucial activity. For instance, weathering is the process that gives rise to mountains, canyons, and caves.
There are three types of weathering and that is physical, chemical, and biological weathering. After chemical weathering, the rock changes form. Therefore, option C is correct.

Sally is a 41 year old female with a history of unsuccessful weight loss attempts. In the past, Sally has tried "almost every diet known to man" and now wants to lose "at least fifty pounds" and "stop fighting with myself". Sally lives alone, and works as an accountant. Her hobbies include reading, spending time with her cat, and shopping. She describes her life as "pretty isolated" and rates her happiness at a 4 out of 10. She explains that when trying to change her behavior, she usually "falls off the bandwagon after a few days", and describes herself as "stuck". She has no history of injuries or preclusions to exercise and has recently had a clean physical exam, with the exception of needing to lose weight.
Describe what approach you would take with Sally to help her change her behavior?
Answer:
the approach has been described below
Explanation:
I will have to use motivation as a way of enhancing change in the life of Sally. From this question, she seems to be a lonely lady, with low self-esteem and no physical activity. The first thing I would do is to help to get her out of monotony by motivating her.
Once motivated, I would help plan her diet and add combinations of physical activities. These activities may include walking and running. With time an expert would take over her physical training.
She has to make time for other activities such as yoga or community work. The purpose for this is so she can meet and connect with other people, this would give her a sense of belonging. And would help boost her self image.
In conclusion, Sally needs a combination of physical and emotional therapy in order to change her lifestyle.

A cell in G1 of interphase has 12 chromosomes. How many chromosomes and DNA molecules will be found per cell when this original cell progresses to the G2?
Answer:
In G2 phase, there are 12 chromosomes and 24 DNA molecule.
Explanation:
There are two DNA molecules per chromosome. In G2 phase, there are 12 chromosomes and 24 DNA molecule.
In Prophase 1, Chromosome - 12, DNA - 24
In Metaphase 1 , Chromosome - 12, DNA - 24cell.
In Anaphase I chromosomes -12, DNA -24
In Prophase II, Chromosomes -6, DNA -12
In Anaphase II of meiosis - Chromosomes -12, DNA -12
If mitosis happens in our gonad cells that produce egg or sperm. How will it impact the progeny's chromosome number? Emphasize also the point why is meiosis so very important.
Who understand this
Explanation:
If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.
In cells, driving an unfavorable process by coupling it to a favorable one requires the availability of compounds that can undergo reactions with large negative free energy changes. Such substances can be thought of as energy transducers in the cell. Explain the reason that many of these energy-transducing compounds are organic phosphates such as ATP.
Explanation:
In the final stage of respiration, ATP is formed through a series of electron transfer reactions within the cytoplasmic membrane that drive the oxidative phosphorylation of ADP to ATP. Bacteria use various flavins, cytochrome, and non-heme iron components as well as multiple cytochrome oxidases for this process.

Diabetes is a disease characterized by the inability to break down sugars. Often a person with diabetes has a defective DNA sequence that messes up the code for making insulin. Suppose a person has a mutation in their DNA, and the first triplet for the gene encoding insulin is CCC (instead of CCA). Determine what amino acid the new DNA triplet codes
Answer:
The new CCC codon codes for proline, while the original CCA codon also encodes for proline
Explanation:
A synonymous substitution is a mutation produced by the substitution of one nucleotide for another in an exonic gene segment which doesn't modify the original amino acid in the protein sequence. Moreover, a silent mutation is any alteration in the nucleotide sequence that does not produce an observable effect on the organism's phenotype. The example above describes a synonymous substitution because the new codon (CCC) also codes for the same proline amino acid as the original non-mutated codon, thereby the resulting protein sequence remains unchanged. Consequently, in this case, mutations associated with diabetes are located at other gene regions. The genetic code is degenerate because different codons can code for the same amino acid.
