The element lithium has two common isotopes: Li–6 and Li–7 If the average atomic mass of lithium is 6.94004 u, determine its percent isotopic abundances. Step by step and explain.
First we need to determine the average atomic mass of these isotopes.
The atomic masses of Lithium-6 and Lithium-7 are 6.0151amu and 7.0160amu respectively.
Now that we have that, we need to set up the relative abundance problem.
We can do that using the formula (M1)(x) + (M2)(1-x) = M(E)
Because you asked for details, I'll explain what each variable stands for-
M1 = the mass of one isotope
x = the relative abundance
M2 = the mass of the second isotope
M(E) = the atomic mass of the element from the periodic table
Therefor all we do now is plug in our respective variable.
M1 = 6.0151amu (Lithium-6)
x = unknown relative abundance
M2 = 7.0160amu (Lithium-7)
M(E) = 6.94004amu
Now the formula plugged in will look like this:
6.0151x + 7.0160(1-x) = 6.94004
Now doing some quick math, we can determine that x=0.07589
For the last step we need to find the percent abundance of each element, which is quite simple. We take X and multiply it by 100 to find Lithium-6, so 0.076 x 100 = 7.6%
and since then we use 1 - X, so 1 - 0.076 = 0.924
We take that and also multiply it by 100, so 0.924 x 100 = 92.4%
Conclusion:
The abundance of the Lithium-6 isotope is 7.6%, and the abundance of the Lithium-7 isotope is 92.4%.

If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is:
Answer:
It is dominant over "dwarf plant."
Explanation:
If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is it is dominant over "dwarf plant."
What is dominant traits?Dominant traits are always explained when the related allele has dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
The frequency of expression of dominant and recessive traits can be Dominant traits = always / Recessive = sometimes.
According to the question if there is self cross TT×tt then there is TT, Tt, Tt and tt, which means there is a 75% possibility of dominant trait and 25% recessive.
A dominant trait has an inherited trait or characteristic that appears in an offspring and covers the effects of another allele and/or prevails or exhibit its trait above another.
Therefore, If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is it is dominant over "dwarf plant."

Which is the BEST statement about joint flexibility?
Answer : D
Explanation : It varies from joint to joint.
Hope this helps you!
The amount of flexibility can vary greatly from joint to joint and is affected by various factors such as joint structure, muscle strength and elasticity, age, and physical activity level. Hence option D is correct.
What is joint flexibility?Joint flexibility refers to the range of motion (ROM) of a joint or a group of joints. It is the ability of a joint to move through its full range of motion without causing any pain or discomfort.
Joint flexibility is an important aspect of physical fitness and is essential for performing daily activities and participating in sports and exercise.
Joint flexibility is determined by several factors, including the anatomy of the joint, the length and elasticity of the muscles surrounding the joint, and the presence of any injuries or medical conditions affecting the joint.
Some joints, such as the shoulder joint, are naturally more flexible than others, like the knee joint.
Flexibility can vary between individuals and between different joints in the same individual. For example, someone may have very flexible hip joints but limited flexibility in their shoulder joints.
Similarly, an individual's joint flexibility can also be influenced by age, gender, and activity level.
Hence option D, It varies from joint to joint. is correct.

Fill out the data table below with the range of each factor that will produce the optimal number of oxygen bubbles.
The optimal ranges for the formation of oxygen bubbles vary between each plant, however, only water, c02, and temperature are limiting factors for photosynthesis.
This question is based on observations made during the course of an experiment designed to measure the optimal ranges at which oxygen bubbles form, given that these are an indication of photosynthesis.
Due to this, the information given will be generalized. Firstly, there is no exact optimal range of light for the formation of oxygen bubbles (photosynthesis) given that this is not a limiting factor.
Excess of light will have no effect on photosynthesis, only the lack of light can cause negative effects, therefore any light past the minimum threshold is fine.
On the other hand, water, light, and C02 are in fact limiting factors and have optimal ranges. For water, this optimal range varies greatly and therefore I cannot offer a general value, but an excess of water will "drown" plants by not allowing the formation of air pockets in the soil.
C02 sits at an optimal range of 1,000-1,300ppm for the best results. Lower concentrations cause a lower rate of photosynthesis given that it is the primary substrate for the process to begin. At too high levels, plants will have to adapt which can slow the process.
Finally, temperature is also a limiting factor for photosynthesis. Its exact value cannot be given since it varies greatly between plant species.
However, in general, terms, since it is an enzyme-dependent reaction, we can apply the general temperature at which enzymes function best which is around 37 degrees.

In sexual reproduction, will an offspring show a recessive trait if just one of its parents has recessive alleles for that trait? Explain your answer.
Answer:
No, they will not
Explanation:
In this question, we assume that the parents have genotypes of rr and RR (I use "r" out of convenience). If we cross both of these parents, it is impossible for any of the offspring to be rr like the one parent. They would all be heterozygous. If the other parent had a single recessive allele, then it would be possible.

Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms; the genes they contain; and the ecosystems they form on land and in water. Biological diversity is constantly changing. The source of this diversity is evolution, the process of gradual change during which new species arise from older species. Evolutionary biologists study the evolution of living things in everything from the microscopic world to ecosystems. There are so much duversity in life on the Earth because there are great numbers of species on the earth, the present day organism are the end product of about 3.5 billion years of organic evolution on earth.
What are MAD (mitotic arrest deficient) proteins and when are they important in the cell cycle?
Answer:
The mitotic arrest deficient protein MAD2B (MAD2L2) is a member of a MAD family of proteins and shows 48% similarity to MAD2 (MAD2L1) [1], [2]. Both MAD2 and MAD2B can bind to the anaphase promoting complex or cyclosome (APC/C), which is a downstream target of the mitotic spindle checkpoint.MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.
The cell cycle ensures the duplication of the genome and its distribution in daughter cells by passing through a coordinated and regulated sequence of events.
A series of checkpoints guarantee the orderly progression of the phases of cell division and the correct distribution of the duplicated genetic material in the daughter cells.
The checkpoints during mitosis are:
At the end of stage G1 and before S.Before anaphase in mitosis.DNA damage checkpoints in G1, S or G2.The checkpoint before anaphase in mitosis guarantees the separation of chromosomes, and operates by activating the Mad2 protein that prevents the degradation of segurin, until the conditions are appropriate.
That is, the Mad2 protein prevents the segregation of sister chromatids until they have all bound to the spindle.
Therefore, we can conclude that MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

If two alleles of different genes are in close proximity with each other on the

Meiosis is the type of cell division that takes place in gamete( sperm and egg cells) production. The alleles are responsible for the phenotype of an
