Answer:
Genotype frequencies25% DD
50% Dd
25% dd
or
1 DD: 2 Dd: 1 dd
Phenotype frequencies75% Dark brown, 25% light brown
or 3 dark brown: 1 light brown
Explanation:
Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.
D d
D DD Dd
d Dd dd
25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown, since it has two copies of the dark brown fur allele (DD)
50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown fur (d).
25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)

1. John observed bacteria at 100X under the oil immersion and then decided to go back to 40X
objective by raising the oil objective a little to avoid the damage to objective lens. Critique his
technique. (1 pt.)
Answer:
See the answer below
Explanation:
In the first instance, the 100X objective does not have any business touching the slide on the stage so that there would not be any reason to raise it a little in order to go back to a lower objective. At higher objectives, only the fine adjustment should be used to bring the object into focus so as to avoid the objective lens from touching the slide which can damage the objective and or break the slide on the stage.
For the X100 objective to be raised in order to avoid a damage to it, it means John allowed the objective to come too close to the slide in the first place. This should not have been so.

Loss-of-function mutations in the coding region of the homologous gene in humans result in loss of hair, teeth, and sweat glands, as in the toothless men of Sind (India). What does this suggest about hair, teeth, and sweat glands in humans? Select the two correct answers. a) The phenotype of loss of Eda function in humans indicates that Eda has been co-opted by evolution to control different aspects of development, as it does in sticklebacks. b) The phenotype of loss of Eda function in humans indicates that human Eda protein and stickleback fish Eda protein contain structurally similar DNA-binding domains. c) The phenotype of loss of Eda function in humans indicates that Eda controls multiple aspects of human development, either directly by controlling each tissue type independently or by controlling a tissue that is a developmental precursor to the affected tissue types. d) The phenotype of loss of Eda function in humans indicates that human hair and teeth might be homologous to stickleback fish bony plates. e) The phenotype of loss of Eda function in humans indicates that hair, teeth, and sweat glands are homologous structures.
Answer:
c) The phenotype of loss of Eda function in humans indicates that Eda controls multiple aspects of human development, either directly by controlling each tissue type independently or by controlling a tissue that is a developmental precursor to the affected tissue types.
e) The phenotype of loss of Eda function in humans indicates that hair, teeth, and sweat glands are homologous structures.
Loss-of-function mutations in the coding region of the homologous gene in humans result in loss of hair, teeth, and sweat glands, as in the toothless men of Sind (India). This suggestion in their hair, teeth, and sweat glands indicates that a) The phenotype of loss of Eda function in humans indicates that Eda has been co-opted by evolution to control different aspects of development, as it does in sticklebacks. c) The phenotype of loss of Eda function in humans indicates that Eda controls multiple aspects of human development, either directly by controlling each tissue type independently or by controlling a tissue that is a developmental precursor to the affected tissue types.
Ectodysplasm A (EDA) is known as a transmembrane protein in the human body that is responsible for the development of ectodermal tissues of the human skin and teeth.
The cooption of Eda with evolution is likely to bring about changes in the development which results in phenotypic loss of Eda. Various genetic studies reveal the orthologous nature of the Eda gene, indicating a comparable method of development, and Eda plays a part in the control of embryonic ectoderm growth, which is essential for the formation of teeth, hair, as well as the sweat gland.
Therefore, we can conclude that Option A and C are both correct from the following options.

Answer the question - Why is it important for scientists and engineers to work together to solve problems?
Answer:
it is important for them to work together because they can come together with the results form each person and see which is right and which is wrong and learn for their mistakes
Explanation:
Using cases to reason—Scientists and engineers often have to solve problems that others have confronted before. When scientists and engineers work to solve a problem, they may write up their experience as a case study for others to learn from. They will even write up the case study if their solution did not work.

Chameleons have a long tongue used to catch insects. The five toes on each foot are bound in two separate groups: one group of two toes and one group of three toes. This allows chameleons to grasp onto branches. Chameleons also have a flexible tail they use to hold onto branches, and they can change the color of their skin to communicate with other chameleons and for camouflage.
Which statement about chameleons refers to the expression of a trait that is most influenced by the environment?
Answer: Chameleon change the color of their skin to communicate with other chameleons and for camouflage.
Explanation:
The statement that refers to the expression of a trait that is most influenced by the environment is: The chameleon changes its skin color to match its surroundings, option A is correct.
The ability of chameleons to change their skin color is a remarkable adaptation that allows them to blend into their environment for both communication and camouflage purposes. This trait is highly influenced by the environment because the chameleon's color change is a response to external stimuli such as light, temperature, and the presence of other chameleons.
When a chameleon is in a green environment, for example, it can change its skin color to green, effectively camouflaging itself. Similarly, when it needs to communicate or display aggression, it can change its color to brighter or darker shades. This color-changing ability is an essential survival mechanism that allows chameleons to adapt to their surroundings and avoid predators or attract potential mates, option A is correct.
