Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale. The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.
A model of a gene, DNA, and a chromosome is shown here. A researcher tags the gene with a heavy radioactive isotope (P-32). Which statement predicts the outcome of the radiolabeling on the gene, DNA, and chromosome while differentiating between the three components of the model?
Answer:
The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes
Explanation:
Genes are made of DNA, but there are many (numerous) genes found along chromosomes. Only a small portion of the chromosome will be radiolabeled.
The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes.
What is the relationship among DNA a gene and a chromosome?
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body.
Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Thus, The gene will be radiolabeled, but only a portion of the chromosome will display P-32 because genes are smaller than chromosomes.

Explain why Calix having X chromosomes from his mother AND father meant chromosomal rearrangement was not the cause.
Answer:
Chromosomal rearrangment was not the cause because it wouldn't lead the mass of DNA per cell in Calix to appreciate by 40fg. It also wouldn't explain how he ended up with an additional sex chromosome altogether.
Explanation:
Chromosomal rearrangement occurs when one chromosome receives additional DNA while a different chromosome is missing DNA.

Each gene in a cell's DNA codes for a specific protein. True of False
Answer:
True
Explanation:
Answer:
true
Explanation:
The genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.

Good and conducive environment should be provided for the animals.
Routine cleaning to avoid outback of diseases
Adequate resources should be provided this include food to avoid eviction of important species.
Geosphere is made up of the crust they form the layer of soil that support growth of plant and also supply nutrients.
Atmosphere is made of gas some of which help sustain life. Example is oxygen, carbon dioxide
Hydrosphere form the liquid portion of the earth it included large water bodies that serves as habitat for aquatic organism.
Oxygen and carbon are been released into the atmosphere where they are been taking up by plant or animal dead and remains of this organism lead to the release of this gases in both organic and in organic form back into the soil where it is taken up by plants back into the atmosphere and some are washed in the water bodies.
Plants takes in carbon-dioxide from atmosphere, absorbs nutrients from the soil through their root and water from the water table needed fro their growth.

Describe the organisms reproductive strategy:
discuss how this strategy is an adaptation for this organism:
Answer:
I will go with sponges :)
Sponges reproduce asexually. The parent begins budding, when the buds grow to a certain point, they break off and drift with the oceans current to a new place, settle down into the sand or rocks, and start the cycle all over again. Since sponges are stationary organisms (meaning that they cannot travel on their own.) They rely on the oceans current to spread their species across the oceans.
Answer:
I would do a Moon Jellyfish
Explanation:
Moon jellyfish reproduce during two different stages in their life cycle. During the medusa stage, they reproduce sexually by releasing sperm and eggs into the water. The method of reproduction used by jellyfish polyps is known as budding, and it does look like a plant growing a new bud for a flower. The polyp essentially clones itself. The clone buds out of the original polyp and detaches to float freely in the water.
