Explain how Carbon is passed from photosynthesis to cellular respiration then back.
The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

1. Name the 4 biomolecules that are found in different foods:
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.

There are several different types of cells in our body including bone, cartilage, blood, muscle, and nerve cells. Regardless of the type of cell they all have the same ___ [ Select ] ___ but different ___ [ Select ] ___
Answer:
This question is incomplete
Explanation:
This question is incomplete and hence makes it difficult to be accurate because of the absence of options. However, for the first blank space, what human cells have in common (with each other in the same body) is the genetic composition thus it can be said that regardless of the the type of cells, almost all of them have the same DNA or genes. However, presence of the same DNA does not mean they carry out the same function. This is as a result of a process known as differentiation.
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.

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.

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.

Si durante la division de las celulas de la raiz de una planta se aplica una sustancia x que destruye el complwjo de golgi de estas celulas¿cual sera el efecto esperado en dicho tejido
Answer:
cada célula tendrá dos núcleos
Explanation:
El complejo o aparato de Golgi es un organela compuesta por un grupo de membranas apliladas una sobre la otra formando una serie de sacos aplanados. El complejo de Golgi tiene diversas funciones: maduración, modificación (glicosilación), transporte y secreción de proteínas. En células vegetales, el aparato de Golgi sintetiza vesículas que forman parte del tabique telofásico el cual sirve para dividir el citoplasma de células vegetales durante la citocinesis. En consecuencia, si se eliminara esta organela, el tabique telofásico no se formaría y las células resultantes estarán compuestas por dos núcleos.
As the average kinetic energy of the particles in a gas increases, which of the following
occurs? (1 point)
The temperature of the gas increases.
The temperature of the gas decreases.
The number of particles increases.
The number of particles decreases.
Answer:
Amontons’s law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure
Why can't the air just rise and go up?
it's sinking
it's spinning
Air does rise and go up. For example, hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air much like wood floats on water because wood is less dense than water. keep this in consideration though, as the hot air cools and sinks back to the surface of the earth, there it gets warmed by the ocean only to rise again. This is called a convection current. In conclusion, air does indeed rise and go up.

B.
arachnids, crustaceans, myriapods
С
crustaceans, insects. molluscs
D insects, myriapods, nematodes
Answer:
Arachnids, crustaceans, myriapods.
Explanation:
Arthropods are animals that form the phylum Euarthropoda. This phylum includes the arachnids, crustaceans, myriapods, and insects. The defining characteristic for an animal to be considered an arthropod is that it has to have an exoskeleton, meaning that the skeleton of the animal is acting as a shell to the body, covering it from the outside.
At present, all of the species of arthropods are small in size, though in the distant past there were speciemens that can be considered as medium-sized or even large. The exoskeleton has its advantages and disadvantages. An advantage is that it is very hard and it covers fully the internal organs, thus protecting them. A disadvantage is that it limits the size to which these animals can grow as the exoskeleton cannot support the weight of the body after certain point.

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.
