When a substance is added to meat, amino acids are produced.
What is this substance?
A) a hormone
B) an enzyme
C) an oil
D) water
The answer is B an enzyme ！
Answer:
[tex]\boxed {\boxed {\sf Enzymes}}[/tex]
Explanation:
Meat is a good source of protein because it is the main component. Hormones, oil, and water won't really produce a substance when added to meat. Enzymes break down different substances. The right enzyme can break down proteins. The monomer, or building block, of protein is an amino acid. Therefore, when a protein is broken down, amino acids are produces.
So, from the information above, we can assume that the substance is an enzyme. Enzymes break down meat/protein into amino acids.
Organ systems maintain which of the following at
just the right
levels to support life processes?
a.) pH
b.) Carcinogens
C.) Temperature and pH
d.) Carcinogens and pH
Answer:
C.) Temperature and pH
Explanation:
Organ systems maintain the right temperature and pH levels to support life processes.
This is known as internal regulation or homeostasis.
Processes that support life requires some amount of fairly constant conditions for optimum level of metabolism to be attained. When the conditions are poor or in excess, reactions can greatly suffer. The ability of complex organism to maintain the right levels to support life processes is called homeostasis. pH and temperature are very important to all living organisms.Answer:

Select the correct locations on the image. The diagram illustrates the evolution of the universe, starting from the big bang. Each concentric circle represents a stage in the evolution as stated by the big bang theory. The arrows illustrate the changes that happened after the big bang and leading up to the stage where gases were formed that later led to the formation of stars and galaxies. Choose the inaccurate statements on the diagram.
Answer: the universe keeps expanding
Explanation:
Universe kept expanding is an inaccurate statement on the diagram.
What is big bang theory?The most popular theory for how the universe came into being is called the Big Bang Theory. Simply expressed, it states that the universe as we now understand it originated from an unimaginably hot and dense single point and expanded over the course of 13.7 billion years, initially at unfathomable speeds and subsequently at a more palpable pace.
The universe's expansion, cosmic microwave background radiation, abundances of the lightest chemical elements, age of the earliest known stars, and abundances of these elements are some of the major evidences for the big bang idea.

During cellular respiration what is the direct source of the energu used in the cells of consumers?
Answer:
Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids, and amino acids.
Explanation:
Heterotrophs are consumers; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.) made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.
Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration: C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
Sexual reproduction in animals depends on the production of gametes. Which of these processes produces gametes in animals?
Answer options:
Mitosis Fertilization Meiosis Binary FissionAnswer:
Meiosis
Explanation:
Meiosis is a specialized type of cell division that produces gametes. Diploid parent cells, after DNA replication, undergo two rounds of meiosis to produce four haploid gametes.
Mitosis produces daughter cells for growth and repair of organisms. It produces two identical daughter cells from a parent cells.
Fertilization is when two gametes fuse to create a zygote.
Binary fission is when bacteria undergo asexual reproduction to produce two identical daughter cells.
Option C is correct. the gametes in animals are produced by Meiosis.
Meiosis:
It is a type of cell division in which a cell divide to form four Haploid daughter cells.
It usually occurs in the germ cells to produce gametes.Meiosis is completed in 2 phases.Gametes fertilise to form zygotes.In binary fission is cells divide to form 2 nearly identical cells. In Mitosis, cells divide to form two identical diploid cells.Hence, Options A, B, and D are incorrect.
Therefore, option C is correct. the gametes in animals are produced by Meiosis.

E. Other
Answer:
I think cell membrane is answer
Viruses are able to invade cells after first attaching to their Cell membrane.
What are viruses?A virus is an infectious microorganism made up of a protein-coated segment of nucleic acid (either DNA or RNA). A virus can't multiply by itself; it has to infect cells in order to utilise the host cell's components to make copies of itself.
A virus frequently causes harm to the host organism by killing the host cell in the process. AIDS, COVID-19, measles, and smallpox are well-known examples of viruses that cause human disease.
Viruses can infect people. But in reality, viruses infect a wide variety of organisms. For example, there are viruses that infect fungi and viruses that infect bacteria.
Therefore, Viruses are able to invade cells after first attaching to their Cell membrane.

Answer:
Carbohydrates, proteins, lipids and nucleic acids.
Explanation:
Biomolecules are organic and are carbon containing and are of four types which are carbohydrates, proteins, lipids and nucleic acids.
Carbohydrates are part of our major diets and are found in grains, fruits and vegetables and so on.
Carbohydrates are energy producing food through glucose.
Lipids contain both fat and oil and they are hydrocarbon and non polar molecules that don't dissolve in water. They provide energy, insulation in the environment and are major constituent of plasma.
Proteins are organic molecules found in meat, milk, beans, cheese e.t.c.
They are body building food or serve as building blocks.
They are enzymes and hormones which are involved in body mechanisms.
Nucleic acids are composed of deoxyribonucleic acid(DNA) and ribonucleic acids. They are the genetic constituent of living organisms and they carry the genetic information.
Describe three environmental considitons that increase the rate of transpiration in plants, explaining how they operate:
Explanation:
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for support C. nitrogen-fixing bacteria and the roots of legumes D. pigs feeding at a trough
Answer:
A. red blood cells containing malaria
Explanation:
Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.
When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.
Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.
FOR THE SECOND TIME-----Ughhh can someone answer this dang biology question I cant!!!!! I will mark you brainliest!!Referring to the graph, what phases together would account for approximately 25% of the time spent from a cell in the cell cycle?
A) M phase and S phase
B) S phase and M phase
C) G1 phase and M phase
D) G2 phase and M phase
Answer:
D. G2 phase and M phase
Explanation:
If we are looking for what takes up 25% of the graph, that would be the last option. If you look at G1, it takes up about 50%. So, G1 phase and M phase would take up more than that, and we want 25% not 50+. The M phase and S phase would take up about a third, so no. The G2 phase and M phase takes up roughly 25% or, it's the closest to this.
Why do heart cells have different characteristics than skin cells???
Heart cells have different DNA than skin cells.
Heart cells reproduce by mitosis.
Heart cells express different genes than skin cells.
Heart cells reproduce by cell differentiation.
Answer:
Heart cells express different genes than skin cells
Explanation:
Cells contain instructions for their gene expression within stretches of DNA called genes, which is expressed and translated into protein.
Somatic cells are cells which contain the organism's chromosome number. They contain the entire karotype- and divide/ replicate through mitosis. In several stages of mitosis, DNA becomes condensed, is unwound and replicated, then packaged into two identical daughter cells.
All somatic cells start out undifferentiated (as stem cells). AFter the process of differentiation, they undergo changes in gene expression to become specific cell types, through processes like methylation and gain maturity.
