uncovering a cluster of Brachiopods You have a second group working about 300 feet above the bottom of the canyon, uncovering impressions from a variety of plants
such as fems and horsetails. While you are waiting for the exact age of the rock layers to be determined, what can you tell about the age of the fossils based on
where they are
A. You cannot determine anything yet.
B. They are all about the same age.
C. The plants must be older than the Brachiopods.
D. The Brachiopods must be older than the plante

Answers

Answer:

C

Explanation:

because the plants are farther down lol

Paleontology establishes the geological age of the organisms. Based on the height of the fossils discovered at the Grand Canyon, it can be concluded that plants were older than the Brachiopods. Thus, option C is correct.

What are fossils?

The dead remains and decaying materials of the plants and animals stored and preserved under the sediments and rock layers over a period of many years are said to be called fossils.

The fossils are evidence of the evolution as well are used to determine the geological age of the species based on their occurrence of them in the rock layers.

The fossils of plants like horsetails and ferns were found 300 ft above the Canyon while Brachiopods at 10 feet above Canyons that tell that plants were found earlier than the former species.

Therefore, option C. the plants existed prior to the Brachiopods.

Before Pasteur's experiments using beef broth and flasks with S-shaped tubing, most people thought that new cells formed by____

Answers

Answer:

spontaneous generation

Explanation:

Spontaneous generation is the idea that living organisms arise from nonliving matter. Louis Pasteur was a French chemist who designed a series of experiments to determine whether a sterile nutrient broth could spontaneously generate microorganisms. He added nutrient broth to two flasks, curved their necks into S shapes, and finally boiled the broth to eliminate any potential microorganism. Pasteur did not observe any microorganisms in the flasks with the S-shaped necks, thereby showing that microorganisms present in the air were responsible for contaminating nonliving material and thus rejecting the idea of spontaneous generation.

Communication between neurons occurs from contact between the two neurons. when the intensity of the action potential increases past a threshold. when action potentials trigger the release of neurotransmitters. because of the all-or-none response. through the selective permeability of the axon.

Answers

Answer:

The correct answer is - when action potentials trigger the release of neurotransmitters.

Explanation:

Communication between neurons takes place by signaling that can be either chemical signaling or electrical signals. Communication between neurons occurs at very small gaps known as synapses.

These synapses have two specialized cells that help two neurons communicate by one to another to allow for chemical transmission. The chemical that isreleased due to the stimulation of the action potential in order to communicate the neurons are known as neurotransmitters that allow for transmission.

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in the laboratory. Which statement best provides evidence that the substance is a mutagen? -The cells die within hours of being exposed to the chemical. -The cells grow more quickly than those that were not exposed to the chemical. -The cells change after being exposed to the chemical, and this change is passed to the next generation of cells. -The cells continue to divide at the same rate as before they were exposed to the chemical.

Answers

Answer:

The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

Explanation:

Mutation is a process that occurs from time to time to the genetic material of living cells. Mutation is a change in the nucleotide sequence of a DNA or gene. It is usually caused by errors during replication or induced by an external substance called MUTAGEN.

A mutagen is any substance that causes mutation in an organism. Hence, according to the question, the chemical substance which is thought to be a mutagen will change the cells after being exposed to the chemical, and this change is passed to the next generation of cells.

N.B: Since mutation affects the gene, it is passed on to the offsprings during reproduction.

Chylomicrons are synthesized in intestinal epithelial cells  to transport long-chain triglycerides to the tissues. Therefore, option (A) is correct.

What are chylomicrons?

Chylomicrons are lipoprotein particles made up of triglycerides, phospholipids, cholesterol, and proteins. They are also known as extremely low-density lipoproteins. They move dietary lipids from the intestines to other bodily parts.

Chylomicrons deliver lipids ingested from the gut to the adipose, cardiac, and skeletal muscle tissues, where their triglyceride components are digested by the action of the lipoprotein lipase, releasing the free fatty acids that may then be absorbed by the tissues.

In a cladogram (a type of phylogenetic tree), clades are groups of related organisms. In the past, phylogenetic lists built clades using the idea of parsimony, that the pattern that uses the fewest evolutionary changes is the most likely to be correct. Today, with the use of computers and DNA sequences, the explanation that is thought to be the best is ___________ .

Answers

Answer:

one with the fewest number of genetic differences in the nucleotide sequence.

Explanation:

A cladogram is a diagram capable of showing the relationships among different species and/or group of organisms. In a cladogram, the root indicates the common ancestor, while internal nodes represent the common ancestors of each group. In consequence, this diagram can be used to establish evolutionary relationships in which the start branch points represent common ancestors shared by the organisms found in the 'branches'. Nonetheless, the length of the branches in the cladogram does not represent evolutionary distances among groups. In recent years, cladograms based on DNA sequencing data have been combined with morphological data to establish evolutionary relationships among species.
