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.
Which process cycles carbon through the
atmosphere?
Answer:
In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals.

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.

How is ATP made in photosynthesis?
Answer:
Light is absorbed and the energy is used to drive electrons from water to generate Nicotinamide adenine dinucleotide phosphate or NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.

If two people who are both heterozygous for the trait of a bent pinky finger have a child, what are the possible genotypes and phenotypes?
genotypes is 1:2:1 & phenotypes is 3:1
l hope this helps you
Answer:
When two people heterozygous for the trait of a bent pinky finger have a child, the possible genotypes CC, Cc and cc -in a ratio of 1:2:1- being the phenotypes bent pinkies: straight pinkies in a ratio of 3:1.
Explanation:
Bent pinky finger is due to a condition called Camptodactyly, characterized by sustained bending of a finger due to a deformity in an interphalangeal joint. Pinky finger camptodactyly is a trait that is inherited in an autosomal dominant pattern.
With camptodactyly (bent pinky finger) C Without camptodacilia (straight pinky finger) cThe parental generation is made up of two heterozygous individuals with bent pinky fingers:
♂ Cc
♀ Cc
The offspring of this hybrid cross, according to Mendelian heritage, can be seen in this Punnett Square:
Alleles C c

According to this the offspring will have:
Genotypes:
