how does studying earths rocks and meteorites support the age of earth?
Answer:
Thousands of meteorites, which are fragments of asteroids that fall to Earth, have been recovered. These primitive objects provide the best ages for the time of formation of the Solar System. There are more than 70 meteorites, of different types, whose ages have been measured using radiometric dating techniques.
Meteorites that fall to Earth represent some of the original, diverse materials that formed planets billions of years ago. By studying meteorites we can learn about early conditions and processes in the solar system's history.
Umm.. maybe my answer is not what you needed
I'm sorry ❤️
Answer:
Scientists think that meteorites can get chemicals such as isopropyl cyanide from a space cloud. So, it’s possible that a meteor that had acquired isopropyl cyanide struck Earth and brought life to the planet.

Answer:
The Golgi apparatus is especially developed in cells that have functions related to the secretion of substances, such as cells of the nervous or endocrine system.
Explanation:
The Golgi apparatus is the organelle responsible for most of the modifications that lipids and proteins undergo once their synthesis in the endoplasmic reticulum (ER) has been completed, that is, the Golgi apparatus is a cellular organ whose function is to manage the proteins synthesized by the endoplasmic reticulum in order to transform and export them to the rest of the body. It is made up of flattened cisterns (middle zone) with an entrance zone or face and an exit zone. The proteins enter the Golgi apparatus and are later transported to these cisterns where they are modified by enzymes.

ADP is a molecule related to the energy-storing ATP and it is repeatedly regenerated back into ATP by having a phosphate group added to it.
- True
- False
Answer:
True
Explanation:
ADP is when ATP loses a phosphate group
It is true that ADP is a molecule related to the energy-storing ATP and it is repeatedly regenerated back into ATP by having a phosphate group added to it.
ADENOSINE TRIPHOSPHATE (ATP):
Adenosine triphosphate also known as ATP is a biological molecule that stores and releases energy for use in living cells. ATP stores energy in its phosphoanhydride bonds that holds its constituent phosphate groups together. This energy is released for use during phosphorylation when one phosphate bond is broken to form ADP molecule (adenosine diphosphate). Therefore, it is true that ADP is a molecule related to the energy-storing ATP and it is repeatedly regenerated back into ATP by having a phosphate group added to it.Learn more at: https://brainly.com/question/3194235?referrer=searchResults

Sexual reproduction in animals depends on the production of gametes. Which of these processes produces gametes in animals?
Answer options:
Mitosis Fertilization Meiosis Binary FissionAnswer:
Meiosis
Explanation:
Meiosis is a specialized type of cell division that produces gametes. Diploid parent cells, after DNA replication, undergo two rounds of meiosis to produce four haploid gametes.
Mitosis produces daughter cells for growth and repair of organisms. It produces two identical daughter cells from a parent cells.
Fertilization is when two gametes fuse to create a zygote.
Binary fission is when bacteria undergo asexual reproduction to produce two identical daughter cells.
Option C is correct. the gametes in animals are produced by Meiosis.
Meiosis:
It is a type of cell division in which a cell divide to form four Haploid daughter cells.
It usually occurs in the germ cells to produce gametes.Meiosis is completed in 2 phases.Gametes fertilise to form zygotes.In binary fission is cells divide to form 2 nearly identical cells. In Mitosis, cells divide to form two identical diploid cells.Hence, Options A, B, and D are incorrect.
Therefore, option C is correct. the gametes in animals are produced by Meiosis.

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is responsible for the change in the mRNA base?
silent
missense
nonsense
insertion
Answer:
is a
Explanation:
The type of mutation is responsible for the change in the mRNA base is missense mutation. The correct option is B.
What is missense mutation?A genetic change in which a single base pair replacement changes the genetic code in such a way that such an amino acid other than the customary amino acid at that location is produced.
The main distinction among both nonsense as well as missense mutation is that the former introduces a stop codon into the gene sequence, resulting in premature chain termination.
While the second tries to introduce a distinct codon into the gene sequence, rather than a stop codon, resulting in a non-synonymous amino acid.
A missense mutation can be lethal or potentially cause Mendelian disease; it can also be mildly harmful, effectively neutral, or beneficial.
Thus, the correct option is B.

Since a protist reproduces asexually, the offspring can inherit the parent's mutation
A. False
B. True
Answer: B. True
Explanation:
The statement "Since a protist reproduces asexually, the offspring can inherit the parent's mutation" is true.
What is mutation?A mutation is changing or modification in the nucleic acid or DNA sequence of a person. This is a natural process that occurs due to mutagens.
One parent participates in asexual reproduction, which results in kids that are genetically identical to both the parent and each other. Two parents participate in sexual reproduction, which results in children with distinct genetic makeup.
In budding, organisms reproduce by severing new individuals from existing ones, creating organisms that are genetically identical to one another. Since identical children are born via sexual reproduction, the offspring will inherit the mutation. As a result, the answer to this question would be accurate.
Therefore, the statement is true.
