What happens to the states of matter when the temperature changes

Answers

They may either release heat or gain heat. With a temperature increase, the kinetic energy increases and the state of matter will increase (example, ice to water aka solid to liquid)

If the temperature decreases, then the kinetic energy decreases and the state of matter will decrease (example, water vapor to water aka gas to liquid)

What is a food chain.

Answers

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another. In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.

Analyses of the protein ______ can be used to study evolutionary relationships among species because most organisms produce this protein for the electron transport chain in mitochondria.

Answers

Evolutionary relationships among species can be studied when similar structures or materials eg the wings of a bat and the arm of a bird or similar proteins between two different species. This proves to show relationship among organisms.

Analyses of the protein Cytochrome C can be used to study this types of evolutionary relationships.

Cytochrome C is an antioxidative enzyme that is a part of the electron transport chain in mitochondria. Mitochondrion is an organelle that majority of living organisms share in common. This protein is therefore found present in almost all organism carrying out cell respiration. Therefore this protein can be used to analyze and study evolutionary relationship among organisms with this protein.

The cells that have the general role of interacting with target cells and then inducing changes in them are ______.

Answers

The cells that have the general role of interacting with target cells and then inducing changes in them are called T-cells.

What do you mean by Target cells?

Target cells may be defined as a cell that is acted on selectively by a specific agent.

T-cells involve helper T cells (TH cells) and cytotoxic T cells (TC cells) which are represented by a cluster of differentiation CD4+ and CD8+ respectively.

Therefore, the cells that have the general role of interacting with target cells and then inducing changes in them are called T-cells.

Where does respiration take place?

Answers

Answer: respiratory system

Explanation:

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide

Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell's cytoplasm. The energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move.

Answers

Answer:

Deletion

Explanation:

because one base is deleted.

The mutation from A T A C G G T A G C A A to A T C G G T A G C A A is a deletion mutation.

MUTATION:Mutation is referred to as any change in the nucleotide sequence of DNA molecule.

Mutation can be of different types namely: deletion mutation, substitution, insertion mutation etc.

Deletion mutation is a kind of mutation that involves the removal of one or more nucleotide base from the DNA sequence.

According to this question, an original sequence is given as: A T A C G G T A G C A A, mutation occurs and results in the following sequence: A T C G G T A G C A A.

Nucleotide base "A" was removed from this sequence, hence, it is an example of deletion mutation.

what parts of a cell are most likely involved with inherited traits?

Answers

Chromosomes are most likely involved with inherited traits.

What are Chromosomes?

A chromosome is defined as the long DNA molecule which contains part or all of an organism's genetic material. Most chromosomes consist of very long thin DNA fibers coated with packaging proteins where the most important of these proteins in eukaryotic cells are histones.

These structures are found in the nucleus of cells which contain long pieces of DNA. DNA is the material that holds genes and is the building block of the human body.

Chromosomes also contain proteins which help the DNA stay in the proper shape.

Thus, Chromosomes are most likely involved with inherited traits.

Environmental factors typically activate genes in a cell by causing the cell to --
A.produce identical daughter cells through mitosis
B.form haploid gamete cells through meiosis
C.fuse with another cell to increase the size of its genome
D.transcribe specific DNA segments to mRNA for translation

Answers

Environmental factors typically activate genes in a cell by causing the cell to transcribe specific DNA segments to mRNA for translation.

This interaction is an example of environmental factors affecting genetic expression. In these situations, the environment causes specific segments of DNA to be expressed, meaning they are transcribed to mRNA and subsequently used to form proteins.

Meanwhile, other parts of the genome remain or are forced to be silent. This can be a result of mutations or simple biochemical reactions between the environment and the genome.

right lymphatic duct in a radical mastectomy, lymph nodes in the nearby axilla and surrounding region are removed along with the cancerous breast to try to prevent the spread of cancer cells via the lymphoid system. lymphatic vessels from the limb on the affected side are tied off, and because there is no place for the lymph to drain, over time lymphedema causes swelling of the limb.
