The property (quality) of fossils allows scientists to determine the relative ages of rock layers are fossils show change over time as species evolve.
What is the minimum age of a fossil?A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch. Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.
Chemistry is present in this process, more precisely the element Carbon. The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).

How many major categories are fossils grouped into?
Answer:
Fossils are remnants or impressions of ancient organisms that are naturally preserved in stone. While there are hundreds of fossil types, they are often grouped into two major categories: Body fossils, which are the preserved remains of plants and animals; and Trace fossils, which are records of an animal’s behavior, such as footprints.

O B Expanded agricultural regions
O Expanded tourism in cold regions
O Increased frequency of severe weather
Answer:
Option C - Expanded tourism in cold regions
How non human organisms impact nature?
Examine how the circulatory and respiratory system work together to move oxygen through the body.
Answer: The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
Chromosome's tightly coiled structure enables them to be
properly segregated during ____
Answer:
Chromosomes are coiled structures made of DNA and proteins. Chromosomes are the form of the genetic material of a cell during cell division. It is this coiled structure that ensures proper segregation of the chromosomes during cell division. During other phases of the cell cycle, DNA is not coiled into chromosomes
Chromosomes' tightly coiled structure enables them to be properly segregated during cell division.
Chromosomes:Chromosomes are coiled structures made of DNA and proteins.Chromosomes are the form of the genetic material of a cell during cell division. It is this coiled structure that ensures the proper segregation of the chromosomes during cell division.During other phases of the cell cycle, DNA is not coiled into chromosomes. It exists as a grainy material called chromatin.
Thus, we can conclude that during cell division chromosomes' tightly coiled structure enables them to be properly segregated.

[ Choose ] Corals have a _________________ relationship with algae. [ Choose ] Corals are classified as _______________ due to their relationship with algae
Answer:
The correct answer is -
1. Archaea are prokaryotic cells. These are one of the two prokaryotic organism domain. the other is eubacteria.
2. Eubacteria cell wall contains peptidoglycan which is composed of sugar and amino acids.
3. Eukaryotic cells have membrane-bound nucleus or organelles. which distinguishes it from prokaryotic cells.
4. All archaea domain organisms found in extreme conditions such as halophiles, extremophiles, and thermophile.
5. The cell wall of the plant is made of cellulose, a polymer of glucose units.
6. Eubacteria are considered to be the first living organism or form found on earth.
7. Fungi cell walls are made up of a chitin cell wall. which is makes it different from eubacteria and plants.
8. Fungi uses absorption to obtain nutrients. Most of the fungi uses haustaurium to absorb nutrients.
9.Fungi are organism that do not fit in other eukaryotic category. Hence they were classified as separate kingdom in 5 kingdom classification.
10.plants are classifies as autotrophs because they make their own food.These autotrophs serve as primary producers.
11.Corals have a symbiotic relationship with algae. Algae provide food for coral through photosynthesis where as coral provide protection to algae.
12.corals are classified as autotrophs due to their relationship with algae.They are mixotrophs generally because they act as autotrophs with association of algae and capture prey by tentacles thus making heterotrophic nutrition.

A)
The genetic diversity for islands A and C is reduced after genetic drift.
B)
The founder effect is a mechanism of evolution that includes a random
factor that influences allele changes.
Islands A and C had founding members with very different allele
combinations than the original mainland population.
D)
The members of the founding population for island B are the most
representative of the original population on the mainland.
Islands A and C have undergone natural selection, which reduced the
genetic variation of the alleles on each of those two islands,
E)
The statements which are supported by the information in the model of evolution are given below:

If the left primary sensory cortex were damaged along the longitudinal fissure, a person could have trouble detecting sensation in the __________. If the left primary sensory cortex were damaged along the longitudinal fissure, a person could have trouble detecting sensation in the __________. tongue left hand right foot right buccal area
Answer:
right foot
Explanation:
The primary sensory (somatosensory) cortex is a region of the brain that receives nerve signals, which is located in the anterior part of the parietal lobe. The primary sensory cortex processes somatic sensory info from receptors for pain, pressure, touch, and temperature. The primary somatosensory cortex on the left side of the brain coordinates the sensory data of the right side of the body, while the primary somatosensory cortex on the right side of the brain coordinates the sensory data of the left side of the body.

the founder effect.
Answer:
founder effect
Explanation:
When a few individuals are isolated from the rest of the population and can have very different gene frequencies, it is called the Founder Effect. The founder effect is a type of genetic drift in which a small population is isolated. Due to this isolation, the population may have different gene frequencies than the rest of the larger population.
