If an animal fossil was found in a rock, what would be the best way to determine its absolute age?

Biology
1 answer:
LiRa [457]3 years ago
3 0

Answer:

D

Explanation:

Absolute age is defined as the numeric age of fossils.

To identify the absolute age of a fossil,  the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.

Hence, the correct answer is "D".

Classify each of the following as homozygous dominant, heterozygous, or homozygous recessive.
mario62 [17]
First, we will elaborate the terms that are being used.

Heterozygous:
This means that the organism has a set of alleles which are different from one another. One copy may be for the dominant trait and the other for the recessive one.

Homozygous: 
The organism has two copies of the same allele

Dominant:
An allele that will express itself even if only one copy of it is present. These are usually represented by capital letters.

Recessive:
An allele that requires both copies to be expressed. These are usually represented by lower-case letters.


A: Heterozygous

B: homozygous recessive

C: Homozygous dominant

D: Homozygous recessive

E: Homozygous dominant

How many daughter cells result from a parent cell in meiosis?
masha68 [24]

Answer:4 haploid daughter cells

Explanation:

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring.

Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

sergij07 [2.7K]

Answer:

Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Every earthquake is recorded on numerous seismographs located in different directions.
