Why can the geologic time scale change?

Answers

Answer 1

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.

Answer 2
Because it’s different time

Describe the organisms reproductive strategy:



discuss how this strategy is an adaptation for this organism:

Answers

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.

Answers

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.
