Using data, provide evidence that evolution is an ongoing process.

Biology
1 answer:
Vlada [557]3 years ago
3 0

The major evidence that the evolution is still ongoing is mutations that occur. Those changes at gene level happen by chance during the process of copying DNA and change through the populations over time. Individuals who reproduced can pass that mutation to their offspring. When carriers with a specific mutation are better able to survive and reproduce, natural selection will favor them. That is the way of new variant to be passed down and spread through the population.

In the early years, when photo processing was a core activity for industry firms, Kodak was known to be better than most others
krek1111 [17]

Answer:

In photography the act of printing of developing a photograph is called photofinishing process.

In   the aspect of DNA the process whereby the exact copies of genes  sequences present in  DNA  is transferred and copied to the mRNA for subsequent synthesis of  needed protein is called Transcription.This is a process of gene expression in  the cells.Therefore if photofinishing involves the copying  or reproduction of images, then the reproduction of gene sequences  of DNA as RNA  can be linked to transcription of DNA to RNA.

1. Which of the following lists structures from smallest to largest?
ladessa [460]
<span>The correct options are as follows:
1. C.
The double helix, the neucleosome, the coil, supercoil and the chromosomes are all related to DNA although they differ in sizes. The neucleosome refers to a unit of eukaryotic chromosome, which is made up of a length of DNA coiled around histones. Coil and supercoils refers to the structures derived from the wrapping and folding of DNA structure. The chromosome is the the thread like structure composed of nucleic acid, which is found in the nucleus of living organisms.

 2. B.
Mitosis is a type of cell division in which two identical daughter cells are formed from a single parent cell. The process is divided into five stages, which are intephase, prophase, metaphase, anaphase and telophase. The G2 phase of mitosis refers to the second subphase of interphase. At this stage, the cell is preparing for mitosis by continuing to grow and producing new proteins.

3. The correct option is D.
The interphase stage of mitotic cell division is made up of G1, S and G2 phases. In G1 phase, the cell increase in size, produce RNA and synthesize proteins. DNA replication occurs during the S phase. During the G2 phase, the cell continue to produce new proteins in preparation for cell division.

4. The correct option is C.
At the metaphase stage, the cell chromosomes allign in the middle of the cell while the centrosomes prepare to separate the sister chromatids. The metaphase stage is the shortest stage in the cell cycle division, it only take about 4% of the time required to complete a whole cell cycle.</span>

What is the genotype for red hair?
Basile [38]

The genetics of red hair appear to be associated with the melanocortin-1 receptor (MC1R), which is found on chromosome 16. Eighty percent of redheads have an MC1R gene variant.

I cannot find this source for this I'm sorry. I meant to add it but I lost the site

Bone marrow transplant taken from a donor and infused through the central vein is coded to what icd-10-pcs code
slava [35]
The ICD-10-PCS code is 30240G4.

Firstly, select "Administration" (section 3) because the procedure is the administration of bone marrow to the patient. Secondly, select "Circulatory" (section 30) because it is being administered in a vein (circulatory system). Third, select "Transfusion" (section 302) because it is being done a transfusion of bone marrow. Then select "Central Vein" (section 3024) because that's the place of administration in the circulatory system. Lastly, go to "Bone Marrow" (section 30240G) as that is what's being transfused and then choose "Transfusion of Allogeneic Unspecified Bone Marrow into Central Vein, Open Approach" (<span>30240G4) because it is not specified what type of transfusion it is.</span>
