What is the principle of superposition? A. The layers of sediment on the bottom are the oldest. B. All layers of sediment are identical. C. In a given region, all layers of sediment form at the same time. D. The geologic processes of today are very different from those in the past.​

Answers

Supperposition = the oldest layer in a sequence of undisturbed sedimentary rock is on the bottom

The principle of superposition is the layers of sediment on the bottom are the oldest. Hence option A is correct.

What is superposition?

Superposition is defined as a quantum system's capacity to exist in several states simultaneously up until it is measured. It is used to transform any circuit into its Thevenin or Norton equivalent. The theorem can be applied to networks of linear sources, linear passive elements, linear transformers, and linear dependent sources.

The original horizontality concept serves as the foundation for the superposition principle. According to the principle of superposition, each layer of sedimentary rock is older than the one above it and younger than the layer below it in a series of unaltered rocks.

Thus, the principle of superposition is the layers of sediment on the bottom are the oldest. Hence option A is correct.

Answers

First of all the cross you made at number 7 is incorrect

top left is correct

top right is wrong, it should be HH since you combined allele H with allele H

bottom left is correct

bottom right should be Hh since you combined allele H with allele h

8. If you cross two parents with HH and HH the offspring can't manifest the recessive gene since it's not present in both parental genotypes.

J The DNA double helix is unzipped, and each strand codes for a single protein.

Answers

Answer:

The information from DNA is used to determine the amino acid sequence of proteins

Explanation:

DNA is the genetic material of living organisms, which serves as a storage molecule for the genetic information needed to synthesize useful products (proteins). The information in the DNA, however, must undergo GENE EXPRESSION in order to be decoded.

The process of gene expression involves two major processes viz: transcription and translation. Transcription is the process by which DNA is used as a template to synthesize mRNA molecule while Translation is the process by which mRNA is used to synthesize amino acids, building blocks of proteins. Hence, the information from DNA is used to determine the amino acid sequence of proteins.

Answers

Answer:

Chloroplasts in the cytoplasm of the cell

Explanation:

The options you were given are the following:

nucleus is located inside of the cell numerous cilia on the outside of the cell chloroplasts in the cytoplasm of the cell a thin membrane around the edge of the cell

The organelles that would indicate that the observed cell belongs to a plant rather than an animal are chloroplasts. Chloroplasts are organelles that conduct photosynthesis - a process in which plants (and some other organisms that possess chloroplasts) get food. In this process, with the help of sunlight, plants transform carbon dioxide, water, and minerals into oxygen, which is released into the atmosphere, and glucose, which they feed on.

Both animal and plant cells have a cell membrane and the nucleus located inside of them.

The cilia are usually found in animal cells.

This is why the third option is the correct one.

All of them repulsion of positive and negative charges.

Answers

Answer: diffusion of ions as a result of their concentration gradients.

Explanation:

Resting membrane potential can be defined as the basic charge of the cell. It is defined by the concentration difference between the ions due to the action of the ion pumps. The differential permeability of the membrane is because of the charge on the ions and leads to the creation of the ion channels. The negative charged ions accumulate on the inner side of the cell.

Compare the carrying power of a small, mountain stream in the mountains with that of a slow large river that is about to enter the sea.


(Note: Needs to be detailed) [this is more of a Geology question]

Answers

Answer:

The carrying power of a small, mountain stream in the mountains with that of a slow large river that is about to enter the sea is explained below in details.

Explanation:

A mountain stream is a river or stream, normally with a sheer slope, running down a mountainside. Stream velocity is most noted in midstream near the exterior and is crawling along the stream bottom and shores due to friction.

The river stalls down at the entrance, so it doesn't have the energy to carry all the sand, dirt, and clay anymore. These deposits create the flat, regularly triangle-shaped tract of a delta.

Most of which type of electromagnetic radiation is given off by Earth's surface at night?
1
gamma rays
2.
ultraviolet light
3.
visible light
4
infrared rays

Answers

Answer:

infrared rays

Explanation:

Infrared A radiation (IR-A) accounts for almost a third of total solar radiation.

Infrared radiation is a part of the spectrum of electromagnetic radiation that continues to the red part of the visible spectrum.

Most of the absorbed energy of the Sun's radiation is converted by the Earth into heat. The surface of the Earth thus heated emits its electromagnetic radiation back into the atmosphere, in the infrared region of the spectrum (long-wave radiation).

Answer:

infrared rays

Explanation:

The majority of the energy collected by the earth in a day is re-emitted, and the majority of this outgoing radiation is infrared.

infrared rays: -

Heat- longer wavelength than the red part of the spectrum.Absorbed by water, carbon dioxide clouds in the earths atmosphere.

Gamma rays :-

Nuclear explosions and lightning are the primary sources of gamma rays. Before they reach the ground, they are absorbed by the earth's atmosphere.

Ultraviolet light :-

The sun is the only source of UV radiation. Vitamin D is produced in the presence of ultraviolet radiation. It is generally filtered out by the earth's atmosphere; otherwise, it might harm living organisms. It is most readily absorbed by all living things on the planet.

visible rays :-

A portion of the electromagnetic spectrum that is visible to the human eyes.These are not re-emitted back from earth surface.

a. most similar to the frog the egg cell came from
b. most similar to the frog the skin cell came from
c. different from both frogs that the cells came from
d. identical to both frogs that the cells came from

Answers

Answer: most similar to the frog the skin cell came from

Explanation:

I just took the test

The tadpole produced by the cloning process will be genetically most similar to the frog the skin cell came from. Thus, the correct option for this question is B.

What is the Cloning process?

The cloning process may be defined as a type of technique that scientists significantly use to construct exact genetic copies of living things. This process is used to create an exact genetic replica of another cell, tissue, or organism.

The copied material, which has the same genetic makeup as the original, is referred to as a clone. The skin cell of the frog is divided through the process of mitosis which produces cells that are genetically identical to the parental cell.

The process of meiosis is carried out by gamete cells or germ cells which produce daughter cells that are not genetically identical to the parental cell.

Therefore, the tadpole produced by the cloning process will be genetically most similar to the frog the skin cell came from. Thus, the correct option for this question is B.
