1. In the late 1800s, Mendel predicted the existence of units of hereditary information or factors. What do we call these units of hereditary information today?  

chromosomes or genes im not sure  

2. Which term describes the form of a gene that produces a specific trait, such as eye color?  

allele  

3. Which term describes a type of trait that is usually expressed only when an organism has two identical alleles for the trait?  

homozygous  

8. Refer to the following information to answer Questions 8 and 9.  

A certain species of grasshopper can have red stripes, yellow stripes, or red and yellow stripes. An RR grasshopper has red stripes, an YY grasshopper has yellow stripes, and an RY grasshopper has red and yellow stripes.  

Which type of inheritance is this an example of?  

codominance  

9. A grasshopper with red stripes mates with a grasshopper with yellow stripes. What ratio would you expect to see in the phenotypes of their offspring?  

all with yellow and red stripes  

10. Which of the following best describes the relationship between a gene and an allele?  

An allele is a variant of a gene.  

11. Which of the following is the best physical description of a gene?  

A gene consists of all of the DNA on a chromosome.  

12. Suppose you cross a true-breeding blue flower with a true-breeding yellow flower. In the next generation, all of the flowers are blue. What does this outcome tell you about the allele for blue flowers?

Ivenika [448]

Question: Describe how a single amino acid substitution causes hemoglobin molecules to stick together. Use what you know about the structure of Hb and HbS, the properties of glutamic acid and valine, and how hydrophobicity causes molecules to behave in water.

Answer:

A Single amino acid must be polar to attract, just like water.

Explanation:

Sickle cell is an genetic illness and it is began by a alteration that arises in the beta sub units of the haemoglobin. Haemoglobin is a tetrameric protein made up of 2 alpha sub units and 2 beta sub units and it is the important part of the blood accountable for oxygen passage. Sickle cell is a illness that consequences from a replacement of a polar amino acid identified as glutamate with a non polar one valine at site six of the beta polypeptide component of haemoglobin. The replacement occurs as a consequence of a alteration in one of the bases in the beta-globin gene from adenine to thymine  . As a outcome of this change, the beta polypeptide chains convert sticky in low oxygen circumstances since the valine sticks out of the chain and interrelates with neighboring non-polar amino acids.

Aneli [31]

Answer:

Twin studies document similarities and differences between twins. When two IDENTICAL twins raised under very DIFFERENT circumstances display similar personality traits, that suggests a strong GENETIC influence on personality. Critics of twin studies suggest that some documented similarities between twins are based on the fact that the twins are still the same age and may have some SIMILARITIES because of it.

Explanation:

It is not fully proved the genetic influence on the personality, and it is not the only factor wich modify the conduct.

It is stated that the personality is the result of a combination of different stimulus as genetic, socio-economic environment, parental education, upbringing rules, etc. Even the personal health can modify the personality.

two identical daughter cell result from mitosis and cytokinesis. In what ways are they " identical"?
erik [133]
They are identical because they are made up of the same materials. we had one cell to begin with, and it didn't so much as clone itself, but split in half to creat 2 daughter cells. ther have the same plasma, same organelles, and most importantly, the same dna in their chromosomes so that when they grow, they grow exactly the same way.

Imagine you have a raised garden
vazorg [7]

At first it will be filled with weeds and insects. In about 5 years, a wider variety of plants will be growing there and larger animals will live there. They are there because of the food and shelter. Then in 100 years, there would be more soil (because of decomposing dead organisms). WIth more soil, bigger plants could grow and larger animals could live.
