Which of the following must be true to consider something to be alive?

1. In a certain plant population, yellow seed color is recessive to green seed color. If a yellow seeded plant is crossed with a

Nuetrik [128]

Let's use A as the dominant allele for green seed colour and a as the recessive allele for yellow seed colour.
If a yellow seeded plant is crossed with a heterozygote,
aa X Aa

the yellow seeded plant would only produce one type of gamete (a) while the heterozygote would produce two different types of gametes (A and a)
If we put this into a Punnett square, we will see that there two two possible genotypes for the offsprings. Either Aa or aa.
Since the allele for green seed is dominant, Aa will exhibit the green seed colour phenotype.
Hence, the chance of getting an offspring with green seed colour is 1/2, or 0.5

Two organisms with genotype aabbccddee mate. These loci are all independent. What fraction of the offspring will have the same g

UNO [17]

Answer:

100%

Explanation:

The given parental genotype is homozygous for all the genes. According to the given information, both the parents are homozygous for five genes and have genotype "aabbccddee". Since both the parents are homozygous for all the loci, meiosis during gamete formation would result in the formation of all same types of gametes from both the parents.

Both the parents will form all the gametes with an "abcde" genetic constitution. The random fusion of gametes with a given genotype will form all the progeny with genotype "aabbccddee". Therefore, the given parents will produce 100% genetically identical progeny to them.

Explain why the process of mitosis is important to you eukaryotic <br> organisms

vichka [17]

The eukaryotic organisms have the process of mitosis but differently than the process of the prokaryotic because the prokaryotic organisms dont have the dna enclosed in a nucleus. Mitosis needs to occur in eukaryotic organims because the cell could keep growing an it is going to be less efficient in moving material across the cell membrane. They reason why mitosis happens is because volume and surface are do not increase at the same rate.

Frontal lobe

Phineas gage, a railroad foreman, suffered damage to a large part of the brain responsible for emotion regulation, planning, and decision making-namely, the frontal lobe.

The frontal lobe is the section of the brain that functions mainly in voluntary movement. The frontal lobe contains the primary cortex which controls activities such as walking. The frontal lobe is also responsible for memory, language, emotion control, good decision making and good communication ability.
