DNA carries the code to make what organic compound
Answers
Answer:
DNA in the cell nucleus carries a genetic code, which consists of sequences of adenine (A), thymine (T), guanine (G), and cytosine (C) (Figure 1). RNA, which contains uracil (U) instead of thymine, carries the code to protein-making sites in the cell. To make RNA, DNA pairs its bases with those of the “free” nucleotides.

irst period class. Then describe why you are using each of those systems.
(Hint: use multiple systems in answer)
Answers
Answer:
Skeletal system and Nervous system.
Explanation:
All the organ systems we would be used for walking are:
The muscular system and Nervous system are used to walk from the front of the school to the first-period class.
• The muscular system has a specific function. This is used to walk because skeletal muscles control our body movements.
• Muscles are attached to bones so muscles cause the movement of those bones.
• So skeletal muscles involved in some activities are walking, running, writing and etc.
• The nervous system also very important which is comprised of the brain, spinal cord, nerves.
• Skeletal muscles are voluntary muscles without the brain's permission they can't work.
• So the Muscular system and Nervous system both are very important for movement because our body movements are regulated by the nervous system.

Small - sand/leaves or small things could be blown away, takes not that long. Large - flood takes rocks/other things away, takes a long time.
What are weathering and deposition?The process by which dead tissues break down and change into more fundamental biological forms is known as decomposition. Decomposition is the first step in the process of recycling nutrients that have been used by an organism to build its body.
Deposition comes after weathering and erosion. A deposition is the third step in the formation of sedimentary rocks. It happens as a result of sediments like pebbles, mud, sand, and small rocks weathering, eroding, and moving.
Therefore, sand, leaves, or other small objects could be blown away quickly. Large - flood takes a long time and removes rocks and other objects.

Which statement describes the effect that a DNA mutation most likely has on an organism?
A. The mutation results in a gene that codes for a different protein.
B. The mutation causes the cell to no longer produce proteins from altered genes.
C. The mutation causes the cell to reject the existing genes and proteins made from those genes.
D. The mutation produces extra copies of genes that the cell uses as backups during protein production.
Answers
The mutation causes the cell to no longer produce proteins from altered genes. So, the correct option is (B).
What is Mutation?A mutation is defined as a change in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA where the viral genome consists of DNA or RNA.
Mutations are of following types:
Chromosomal Alterations.Point Mutations.Frameshift Mutations.Mutation plays an important role in evolution where the ultimate source of all genetic variation is mutation. Mutation is important as the first step in evolution because it creates a new DNA sequence for a particular gene, creating a new allele.
Thus, the mutation causes the cell to no longer produce proteins from altered genes. So, the correct option is (B).

This is a preserved specimen and your teacher has tasked you with dissecting the mouthparts and laying them out on the dissecting pan with the appropriate labels. Based on the information in the chart, select the best microscope for the job, citing evidence.
A) The crayfish is dead, a preserved specimen, so it would be appropriate to use either electron microscope for the task.
B) You should use the compound light microscope, on the lowest power. You can dissect the mouthparts using a 2D view with this much magnification.
C) The crayfish is a relatively large specimen, even the mouth parts. Since you are dissecting the mouth parts, you need a 3D view: you should use the dissecting microscope.
