What valuable information was gained from Mendel's dihybrid crosses?
Select all that apply.
1. Not all traits are controlled by genes. In most plants, genes only determine traits that affect
flower color.
2. Statistical and probability methods can be used to determine how likely an offspring is to inherit
certain traits.
3. Genes are inherited differently in plants than they are in animals.
4. Inheritance of one trait does not affect inheritance of another.
Answers
Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
What is a dihybrid cross?When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.
In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.
Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.
Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.

How are the DNA strands organized
Answers
Answer:
They are all composed of building blocks called nucleotides that are linked together in a row. its two complementary strands are chemically linked together and are spiraling around counterclockwise, forming a ladder-like double-stranded molecule.
Explanation:
Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Since all these offspring only have one trait for long fur, this trait stays hidden in their DNA and is not expressed in their phenotype. All the offspring will have short fur.
Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Answers
Answer:
test two:
some short fur and some long fur will be seen.
this is because in some cases, the offsprings have only have the trait for short fur or just one trait for long fur and so short fur is expressed in the phenotype. in other cases, the offsprings have only the trait for long fur and so long fur is expressed phenotypically.
test three:
all long fur is seen.
since all the offsprings only have the trait for long fur and no trait for short fur, long fur is expressed in the phenotype.
Assuming a diallelic gene coding for the trait and expressing complete dominance, 1) all short fur. 2)some short and some long fur. 3) all long fur.
According to the information that was provided, we can assume that the trait fur length is coded by a single diallelic gene
• dominant allele F codes for short fur
• recessive allele f codes for long fur
We can also assume that the gene expresses complete dominance.
What is complete dominance?It is the inheritance pattern in which the dominant allele completely masks the recessive allele.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant phenotype. The dominant allele is hiding the expression of the recessive allele.
Many genes show complete dominance.
Cross 1:
Parentals) FF x Ff
F1) 100% short fur
All short fur
Cross 2:
Parentals) Ff x Ff
F1) 1/4 FF + 1/2 Ff / 1/4 ff
75% short fur + 25% long fur
Some short fur, and some long fur
Cross 3:

Consider the numbers of species known to exist on Earth, including the numbers that are being discovered and
the numbers thought to be going extinct. What do these
numbers suggest about biodiversity on Earth?
Answers
Answer:
A high diversity of species is known to exist among insects and land plants; fewer species are known to exist among vertebrates, bacteria, algae, arachnids, Protists, nematodes, mollusks and crustaceans. However, much greater diversity is estimated to exist among insects, fungi, bacteria, algae, and arachnids. Vertebrates are the best-studied organisms but are relatively less diverse than other groups.

First a glucose molecule enters the body cell, and then a glucose molecule is broken down in the cytoplasm. Then, oxygen is used to break down smaller molecules, smaller molecules enter the mitochondrion. Finally, a large amount of energy is released.
Explanation:
After you ate an energy bar full of glucose, the molecules will first enter the cells, prepare to be broken down in the first site, cytoplasm. And now, oxygen takes a part in it, continue to break it down. The smaller molecules now enter the energy source of a cell, which is mitochondrion, the energy will be released here.

what triggers angry in the brain?
Answers
Answer:
amygdala
Explanation:
Answer:
Anger starts with the amygdala stimulating the hypothalamus, much like in the fear response. In addition, parts of the prefrontal cortex may also play a role in anger. People with damage to this area often have trouble controlling their emotions, especially anger and aggression. Epinephrine or adrenalin released by medulla of the adrenal glands, surges at the time of panic and emergency. It provokes stress response and brings out the arousal of extreme emotions like fear, anger or amusement.

Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Which phase of the cell cycle is helicase most likely active?
A) S
B) М
C) G1
D) G
Answers
Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Helicase is more active in the S phase of the cycle. Option A is the correct answer.
What are the events of the cell cycle?
The cell cycle consists of the interphase and the cell division phase, where the cell division takes a little time in comparison to the interphase. The parent cell spends the majority of its time in the cell cycle's interphase and less time in the cell division phase.
There are three phases in the cell cycle's interphase: G1, S, and G2. The cell grows in both the G1 and G2 phases, while the DNA replicates in the S phase.
Hence, helicase is an enzyme that is responsible for unraveling the double helix of DNA by breaking apart the hydrogen bonds between each base pair. Helicase is more active in the S phase of the cell cycle. Option A is the correct answer.

Pressure from similar environments on the organisms over time led to these similar analogous features because of the similar environmental conditions for organisms leads to the physical features that are similar in structure and function. Analogous structures are the structures which are similar in appearance in unrelated or different organisms. These structures have similarities because they perform the same job and not because they share common ancestry.
