Answer:
Breathing is a physical process that involves various organs like the lungs, windpipe, nose, and others for exchanging the gases that are inhalation or taking of oxygen and expelling the carbon dioxide in the body.
Respiration is a chemical process that takes place inside of the cell by breaking the sugar using oxygen taking from breathing to produce energy. These both processes are different, however, interrelated to one another as breathing provides oxygen for respiration, and respiration gives up carbon dioxide to expel out by breathing.

Which statement best descrſoes photosynthesis?
a. when plants produce their own water
b. when plants produce their own sugar
C. when plants produce oxygen and carbon dioxide
d. when plants self-pollinate
Answer:
b. when plants produce their own sugar
Explanation:
Let's look at the products of photosynthesis! During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).
Glucose provides plants with needed food through a process called photosynthesis. This process helps plants convert the energy they take in from sunlight into sugar to nourish the plant. Photosynthesis occurs when carbon dioxide, water and sunlight are combined. Plants use these to form glucose and oxygen.

Give an example of a physical change involving iron and a chemical change involving iron
Answer:
For example, toxicity, reactivity, combustion etc are all chemical changes. When iron rusts then an oxide layer of orange-brown color deposits on its surface due to chemical combination of air and moisture with iron. This is a chemical change.
Explanation:
Hope it helps
FOLLOW MY ACCOUNT PLS PLS
Answer:
As the rust forms on the surface of the iron, it flakes off to expose more iron, which will continue to rust. Rust is clearly a substance that is different from iron. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change.

A rock contains a radioactive isotope that decays to half of its original
amount in 5 million years. When this rock formed, it was made up of 100%
of the radioactive isotope, and 0% of the new element that it decays
If you find this rock and analyze it, and find that it contains only 50% of the
radioactive isotope and 50% of the new element, how old must this rock
be? *
1) 2.5 millon years
2) 10 million years
3) 5 million years
4) 15 million years
Answer:
3) 5 million years
Explanation:
The rock is 5 million years old because the rock contains only 50% of the radioactive isotope. We know that this rock decays to become half in 5 million years. Initially, the rock has 100% of radioactive isotope and 0% of the new element that forms with the decaying of the rock. But 50% of the radioactive isotope decays and 50% of the new element is formed so we can say that it reaches to its half age which is 5 million years.

Inactivation of a cell-surface receptor depends on: the activity of phosphatases in the cytosol. the release of the ligand from the receptor ligand binding site. the concentration of ligand surrounding the cell. the binding affinity of the receptor.
Answer:
the release of the ligand from the receptor ligand binding site.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Inactivation of a cell-surface receptor depends on the release of the ligand from the receptor ligand binding site. This ultimately implies that, the concentration of ligand surrounding a cell, as well as the binding affinity of the receptor significantly affects the inactivation of a cell-surface receptor such as receptor kinase.
The inactivation of a cell-surface receptor depends on solely the concentration of ligand surrounding the cell.
A ligand which has the ability to bind to and alter the function of the receptor that triggers a response is called a receptor agonist. On the other end, ligands that bind to a receptor but fail to activate the response are receptor antagonists.
Ligand cellligand is any molecule or atom that irreversibly binds to a receiving protein molecule, otherwise known as a receptor. When a ligand binds to its respective receptor, the shape and/or activity of the ligand is altered to initiate several different types of cellular responses.
Futthermore, molecules such as hormones and drugs that bind to a receptor are called ligands. The binding can be specific and reversible.A ligand may activate or inactivate a receptor; activation may increase or decrease a particular cell function

How does gravity affect objects of different mass close to Earth, and how does that effect
change as an object moves farther from Earth
Answer: Gravity is the universal force of attraction. ... This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. This means that as you move away from an object the gravitational force decreases.
Explanation:
In this question we are going to answer two questions about the gravitational force that keeps us grounded.
How does gravity affect objects of different mass near Earth?The force of gravity between two objects is the product of their masses divided by the square of the distance between them. That is, the more mass an object has and the closer it is, the greater its force of attraction on another object.
How does it affect change as an object moves away from Earth?The gravitational force decreases, and the object begins to be attracted by other gravitational forces besides that of the earth.
With this information, we can conclude that the gravitational force of the earth keeps us attached to it, and as we move away from the earth we lose these forces of attraction.

A group of researchers are studying stem length inheritance in the garden pea plant (Pisum sativum). They obtain a tall pea plant of unknown ancestry, allow it to self-pollinate, and collect 80 of its seeds. After planting the seeds, they observe the growth of 61 tall plants and 19 dwarf plants. Which of the following best explains the stem lengths seen in the offspring?
A. Stem length is inherited through incomplete dominance.
B. Dwarf stem length is a recessive trait.
C. Stem length is a sex-linked trait.
D. The tall plants likely received more nutrition than the dwarf plants.
Answer:
The answer is B
Explanation:
just cause lol
The study of a living being is called biology.
The correct answer is B.
The characters in the plant are controlled by the genes which are present on the chromosome. The genes are always present in pairs and a single gene is known as an allele. The alleles are as follows:-
DominantRecessive.According to the question, most of the offspring are tall in height due to the dominant allele while the number of the dwarf plant is less as this character is shown by the recessive genes.
The dominant plant suppresses the character of a recessive gene and hence the number of the dominant plant is always more.
Hence, the correct answer is B. Dwarf stem length is a recessive trait.

A population of tree frogs living in the Amazon rainforest have two skin color phenotypes controlled by the same gene. Hozygous dominant and heterozygous individuals have green skin while hozygous recessive individuals have blue skin. In the first generation, analysis of the alleles for this gene shows that 70 alleles of this gene are green, and 130 alleles of this gene are blue in the population. In the second generation, 90 alleles are green and 110 alleles are blue. Finally, in the third generation, 120 alleles are green and only 80 are blue. Based on this data, which description best describes this population of tree frogs?(1 point)
A) The green skin color is being selected over blue skin color.
B) The frogs are randomly mating with each other.
C) The population size of frogs is very large.
D) There are no individuals migrating into or out of the population.
Answer:
A
Explanation: You can see that the green colored frogs were once lower than the blue and as time started progressing the green started getting a higher population over the blue, as the blue decreased.
For the frogs, the green skin color is being selected over blue skin color. This leads to the abundance of the skin color in the third generation.
What is natural selection?
Natural selection refers to a situation in which traits that enable organisms to better survive and adapt in their habitat tend to persist whiole other traits gradually disappear.
In this case, we can say that the green skin color is being selected over blue skin color.

What is the final product of transcription?
A gene
An amino acid
An mRNA molecule
A stop code
here is the paragraph to read from:
Transcription is the process by which an RNA copy of a gene sequence is created. This copy, known as the mRNA, travels from the cell nucleus to
the cytoplasm. There, it directs the synthesis of the protein. The base code in the mRNA controls the order of the amino acids in the protein.
There are 20 amino acids used to make proteins and different codes for each acid. The tRNA reads the code. Then it brings a specific amino acid to
attach to the growing chain of amino acids. Each tRNA carries only one type of amino acid. It only recognizes one specific code. tRNA is released
from the amino acid until it comes to a stop code. Then the protein is set free from the ribosome.
Answer:
An mRNA molecule
Explanation:
Transcription is a process by which the information stored in a specific fragment of DNA called 'gene' is used to produce a complementary RNA molecule, usually a messenger RNA (mRNA). Subsequently, this mRNA is used as template to produce a polypeptide chain (i.e., a sequentially ordered amino acid chain) through the process of translation. A stop codon, also known as termination codon, is a triplet of nucleotide bases within an mRNA that signals the end of the protein when it is synthesized in the ribosome. There are three stop codons (UAG, UAA, and UGA) that are capable of stopping protein synthesis.
