Answer:
The correct answer would be - 25%.
Explanation:
It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.
BbTt is a heterozygous condition and a cross with itself will produce :
Gametes: BT Bt bT and bt
BT Bt bT bt
BT BBTT BBTt BbTT BbTt
Bt BBTt BBtt BbTt Bbtt
bT BbTT BbTt bbTT bbTt
bt BbTt Bbtt bbTt bbtt
Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%

Each of your cells has a set of chromosomes, including
autosomes and sex chromosomes. Explain the main
differences between these two types of chromosomes.
Answer:
in the 46 chromosomes in our body, the autosomes are the first 22 homologous pairs of chromosomes that do not influence the sex of an individual, while sex chromosomes are the 23rd pair of chromosomes that determine the sex of an individual

What is the name of a group of connected and related organisms?
A. Flow
B. System
C. Energy
D. Matter
Answer:
system
Explanation:
Movement of chromosome segment to a non-homologous chromosome. This type of chromosomal mutation occurs when one chromosome swaps genetic information with a different chromosome (this is NOT Crossing Over). O Inversion O Duplication O Deletion O Translocation
Answer:
The correct answer is ''Translocation.''
Explanation:
Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.

When glucose is being formed during the Calvin Cycle, which
molecule/substance provides the carbon in order to make the glucose?
rubisco
water
carbon dioxide
ATP
Answer:
Rubisco.
Explanation:
Las reacciones del ciclo de Calvin añaden carbono (del dióxido de carbono en la atmósfera) a una molécula sencilla de cinco carbonos llamada RuBP. Estas reacciones usan la energía química de la NADPH y del ATP que se producen en las reacciones luminosas. El producto final del ciclo de Calvin es la glucosa.

When a squirrel hears a strange noise that might indicate the presence of a predator, fight-or-flight hormones are released into its system. The hormones help prepare the squirrel's body to do strenuous physical activities, like quickly climbing up a tree, more efficiently. Which statement describes how two organ systems work together to help a squirrel respond to a possible external threat?
Answer:
The flight-or-flight hormones are released by the endocrine system in response to environmental changes detected by the nervous system.

Answer:
The population of peppered moths thrived, because they camouflaged with the bark of the trees, thereby they were not easily seen by predators. Black moths were easily seen by predators and they were eaten as a result. Because the black moths did not survive, they were unable to reproduce offspring with those traits. However, peppered moths were able to reproduce offspring that were also peppered. During the industrial revolution, the colour of the bark darkened. This meant the peppered moths were easily seen by predators, so they were eaten. Black moths camouflaged with the bark, so now they weren't easily seen by predators. Now that the black moths survived, they could reproduce more black moths. But peppered moths weren't able to reproduce more peppered moths because most didn't survive. This is an example of how an abiotic factor, such as bark can affect a population of a species. Because the bark influenced the survival of the moths, some moths with the desirable traits survived, and others with the undesirable traits died.
