How do scientists use ice to study ancient climates

Answers

Answer 1
Counting the yearly layers can date them. The oxygen in the water molecules also holds a key to past climate. Scientists are able to use the oxygen atoms in the glacial ice as a proxy for air temperature above the glacier.
Answer 2

Answer: Ice is very important for studying ancient climates. Ice can preserve the remains of organisms such as a Wholly Mammoth, possibly for hundreds of thousands of years. The details and phenotype of the mammoth such as its fur, can provide evidence of Earth's ancient climate, and where it occurred (which is somewhere that contains ice).

Humans have 46 pairs of chromosomes, with half from each parent. Which of the following best describes why the offspring will receive only half of the parents' chromosomes?
A)Chromosomes assort independently, and crossing-over occurs.
B)Gametes contain homologous pairs from the mother and father.
C)Diploid eukaryotic cells become haploid before fertilization.
D)The cell cycle stops, allowing for extra haploid cells to be made.

Answers

Answer:

C

Explanation:

I am pretty sure answer is C.

Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell, and they contain all the genetic information of an organism because chromosomes assort independently and crossing-over occurs, as in option A.

What is the function of the chromosome in meiosis?

The chromosomes present in the parent cell duplicate in the S phase of the cell cycle, and in the meiosis phase of the cell cycle, the daughter chromatids segregate and form four haploid cells from the parent cell. The child or offspring is the result of the fertilization of the sperm and the ovum, and the zygote is formed from the process that develops into the offspring, and the zygote has half the genetic contents of the paternal and maternal parents. In this way the chromosomes separate in the meiosis.

   

Hence, Chromosomes are structures of nucleic acids and proteins found in the nucleus of a cell, and they contain all the genetic information of an organism because chromosomes assort independently and crossing-over occurs, as in option A.

Carbon-dioxide gas is essential for maintaining life on earth.

Carbon-dioxide present in the atmosphere comes from breathing of animals and volcanic eruption. this carbon-dioxide absorb by the plants (biosphere) in the process of photosynthesis. This carbon-dioxide is incorporated in the soil (geosphere) with the dead bodies of plants and animals and decomposition of these bodies occurs and carbon-dioxide gas again releases in the atmosphere. Carbon-dioxide gas is also dissolved in the water bodies where it is required by the plants for photosynthesis and made food for the marine animals.

The scientific name of an organism is made up of what two group names?

Answers

Scientific names follow a specific set of rules. Scientists use a two-name system called a Binomial Naming System. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species.

Answer:

Genus species

Explanation:

Scientists use a special naming system for organisms. It is made up of two words.

The first word is the genus of the organism and the second word is the species of the organism.

The first word, which is the genus, is always capitalized, but the second is not. Both words are italicized if possible, but if you are handwriting the scientific names, an underline suffices.
