A gardener performs experiments on her tomato plants. When graphing her data, which factor is an independent variable?
the number of fruit per plant
the amount of light each plant receives
the height of each plant
the average circumference of each plant’s fruit
Answers
Answer:
The answer is "the amount of light each plant receives
At the time of graphing the data, the factor that should be considered as the independent variable should be the light amount that each plant received.
What is the plant?The plant should be treated as a living thing that should be grown in the earth and contains the stem, leaves, and roots.
At the time when the gardener performed the experiments on the tomato plants so here, the factor should be the light amount that each plant received.
Therefore, the second option is correct.

Which of the following is NOT an example of evidence that supports the theory of evolution?
A. common genetic ancestors among diverse species
B. fossil evidence suggesting ancient genetic ancestors
C. unnecessary or nonfunctional organs in modern species
D. fossils of the same species found diverse geographic locations
Answers
The statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.
What do you mean by Evolution?Evolution may be defined as a gradual and continuous process that runs over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.
Common genetic ancestors may be diverse into the number of other species due to the theory of evolution. Unnecessary or non-functional organs may be eliminated or shortened due to evolution.
Therefore, the statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.

A. The biologist observed the squirrels and did not test variables.

C. 25%
D. 50%
3. Which statement is true about DNA?
A. DNA is an exact copy from parent to offspring
B. DNA contains genes that hold specific traits for an organism
C. DNA is not necessary for an organism to reproduce
D. Organisms create their own DNA sequence that is not like their parents
Answers
The biologist observed the squirrels and did not test variables. If two plants with the Tt genotype are crossed, 50% is the probability that offspring will exhibit the dominant trait. The correct options are A, D, and B respectively.
What is genetics?The study of genes, genetic variation, and heredity in organisms is known as genetics. It is an important branch of biology because heredity is essential to the evolution of organisms.
An experiment entails manipulating variables to see how they affect a dependent variable. In this case, the biologist observed and recorded what he saw rather than manipulating any variables.
Both plants in this scenario are heterozygous (Tt) for the tall trait, which means they each have one dominant allele (T) and one recessive allele (R) (t).
When they are crossed, each offspring has a 50% chance of inheriting the dominant T allele and displaying the dominant trait of tallness, as well as a 50% chance of inheriting the recessive T allele and displaying the recessive trait of shortness.
DNA (deoxyribonucleic acid) is a molecule that contains the genetic instructions for the development, function, growth, and reproduction of all living organisms.
Thus, the correct options are A, D, and B respectively.

A doctor harvests a single egg from her body. The genotype of her egg is LA. How did her chromosomes line up at the metaphase plate during meiosis
Answers
Answer:
Metaphase I:
Homologous chromosomes are placed in the equatorial planeChromosomes carrying the dominant alleles, L and A, face one of the polesThe homologous chromosomes, carrying the recessive alleles, l and a, face the opposite pole.Metaphase II:
Chromosomes carrying the dominant alleles, L and A, are placed in the equatorial planeOne of the chromatid sisters of each chromosome faces one of the polesThe other chromatid sisters of each chromosome face the opposite pole.You will find the image in the attached files.
Explanation:
During metaphase I, homologous pairs migrate to the equatorial plane. They randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
During metaphase II, fibers of the spindle apparatus take chromosomes toward the equatorial cell plane, where they line up. Sister chromatids are holden together until they reach the Anaphase, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again. Finally, cytokinesis occurs.
In this example, we will assume no crossing-over in the prophase. I will propose the two metaphase stages.
Metaphase I: Pole 1
Chromosome 1 ---------L---- -----------A--------- Chromosome 3
----------L---- -----------A---------
Equatorial plane.....................................................................................................
Chromosome 1 ---------l---- -----------a--------- Chromosome 3
---------l---- -----------a---------
Pole 2
In this scheme of Metaphase I, homologous chromosomes are already aligned in the equatorial plane. Each homologous chromosome is facing a pole. So, in the superior part of the scheme, we have chromosomes 1 and 2 carrying the dominant alleles L and A. Both chromosomes are facing pole 1. Then, we can recognize the equatorial plane, and on the other side, we find the homologous chromosomes 1 and 2, facing pole 2, and carrying the recessive alleles, l and a.
During anaphase I, homologous chromosomes will separate and migrate to different poles. In this example, we are interested in chromosomes carrying the dominant alleles that migrate to pole 1. LL and AA.
Metaphase II: Pole 1
Chromatid 1 ---------L---- -----------A-------- Chromatid 3
Equatorial plane.....................................................................................................
Chromatid 1 ----------L---- -----------A--------- Chromatid 3
Pole 2
During metaphase II, each chromatid sister carrying the dominant alleles faces a different pole. During anaphase II they separate and migrate again.
The total result of meiosis in this particular cell is the formation of 4 haploid cells -gametes-: LA, LA, la, la

Species richness determines the numbers of different species are present in an ecological community. It is a numerical value or count of different species present in a particular community.
The given information or data can only be used to estimate the species richness in the particular forest community as there is data available about the number of species presnt in this community.
Which of the following effects is least likely to be as a result of deforestation?
A: A greater risk of flooding.
B: An increase in biodiversity.
C: An increase in soil erosion.
D: An increase in the level of carbon dioxide in the atmosphere.
Answers
The effect that is least likely to be a result of deforestation is an increase in biodiversity. That is option B.
Deforestation is a practice that encourages the clearing of forests for other purposes such as agricultural croplands, urbanization, or mining activities.
This practice needs to be avoided because:
posses a greater risk of flooding as deforestation erodes the soil.they provide a protective cover for the soil against the action of wind and rain thereby preventing soil erosion.the level of carbon dioxide in the atmosphere decreases as it is cleared by trees during photosynthesis.But deforestation leads to a decrease in biodiversity instead of an increase.
Deforestation can lead to biodiversity loss. This occurs when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct.
