What type of fuel does each energy system produce?.
Answer:
carbon?
Explanation:
Energy systems produce ATP, during every process cellular respiration is the major process of the system.
How ATP as fuel produce by each energy system?During cellular respiration, all the metabolic intermediates finally produce ATP, and in glycolysis, the Kreb cycle produces reducing products which finally oxidize in the electron transport chain.
The electron transport chain produces fuel as ATP, it is an enzymatic chain reaction that produces an electromotive force that is responsible for the production of ATP.
ATP is a major fuel for every cellular process which acts as an energy form that is extracted from metabolic intermediates.
Therefore ATP is a major fuel produced by the system.

In terms of atomic structure, how are the elements of a periodic table group related?
If you take a look at the s-, p-, and d-block elements part of the periodic table, you'll see that they are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. And because of this, elements in the same group often display similar properties and reactivity.

if we have red veins and red blood how do we have blue veins in our bodies FIRST ONE TO ANSWER AND EXPLAIN GETS BRAINILEST PLEASE HELP
Answer:
The colors we see are the result of which wavelengths of light are reflected back to our eyes. Veins appear blue because blue light is reflected back to our eyes.
Blue light does not penetrate human tissue as deeply as red light does. As a result, veins that are close to the surface of the skin will be more likely to reflect blue light back to the eye.”
In short, our veins appear blue because of a trick that light plays on our eyes and how the light interacts with our body and skin. All color works this way as light is a combination of all colors and when it reflects off of certain materials, it absorbs some colors and bounces back others to our eyes.

What does dna have that determines all my traits
Answer:
These sections of DNA that contain information that determine your physical features are called genes. Since you have two pairs of chromosomes, you also have two pairs of genes, one from your father and one from your mother. These pairs of genes then determine certain physical features or traits.

When does a zygote become an embryo?
once the embryo forms a heart, lungs, and brain
a few minutes after the male and female gamete fuse
once the zygote enters a safe environment either inside or outside of their mother
once the zygote starts dividing by mitosis and cell differentiation occurs
Answer:
Explanation:
The transformation of a zygote into an embryo adheres both to nature and to nurture: not only genetics but also environment determines the outcome. This idea has assumed many forms. A territory in the early sea urchin blastula contains clones of founder cells, and each clone contributes exclusively to one territory (Cameron & Davidson, 1991). Both the lineage of a founder cell, i.e. its nature, and the position of a founder cell, which determines how it is nurtured, contribute to its fate. Fertilisation, the topic of the first Forum, fixes the genes; interblastomere communication, the topic here, regulates gene expression. Blastomeres communicate like any other cell – via ligand-receptor interactions and through gap junctions. Saxe and DeHaan review these mechanisms. The definition of ligands and receptors becomes broadened in this context, and cell adhesions as well as gap junctions enter into the story. In spite of these entanglements, it appears that nature uses the same sorts of mechanisms to get cells to specialise that she uses to keep them talking. Thus, neurons and glial cells signal to one another via glutamate receptors and gap junctions (Nedergaard, 1994). Likewise, we expect neurotransmitters (and neurotransmitter transporters) to help signal differentiation. The biophysicist may ask whether electrical properties also play a role, but that we reserve for another Forum. If gap junctions figure in development as fusion pores that pass small molecules and electrical signals between blastomeres, another parallel suggests itself. Brian Dale asked in the first Forum: How does a spermatozoon activate an oocyte? This question, which concerns gamete communication, has produced two schools of thought and remains controversial (Shilling et al., 1994). Do sperm activate oocytes via contact-mediated mechanisms or through fusionmediated mechanisms? Or do both mechanisms occur, as they appear to in development?

The sum of the genetic traits in this population is called its V gene pooly. COMPLETE In guinea pigs, fur length is controlled by one gene. The Fallele generates long fur and the f allele generates short fur. Because only one F copy is needed to show the trait, if a guinea pig has the FF or Ff allele combination, they will have long fur. If they have the ff allele combination, they will have short fur. There is a total of 7 8 alleles in this population, There are 5 Falleles in the population. There are 3 ✓ falleles in the population. Look at the data for a guinea pig population to answer the following questions. COMPLETE Guinea pig 1: Long fur (FF) Guinea pig 2: Short fur (ff) If having long fur helps a guinea pig survive, what would you expect to see change in the population as it evolves? Guinea pig 3: Long fur (FF) DONE Cuinas nin 1. Innn fuar (Cf)
If having long fur helps a guinea pig survive, then it is expected to see the F allele is more common in the population as it evolves.
What is natural selection?Natural selection can be defined as the process of differential survival and reproduction of the fittest organisms.
The fittest organisms are life forms that have allele combinations favoring their survival and reproduction.
In this case, the F allele is an adaptive allele associated with higher fitness in the population.

Elisabeth is an oceanographer. On which of the following research expeditions would she travel from the photic zone to the aphotic zone?
A.) A snorkel trip from the intertidal zone to 55 feet off the beach
B.) A scuba trip from the surface down 100 feet
C.) A submersible traveling from the ocean surface to the abyss
D.) A research vessel from the beach to the open ocean
A research expedition traveling from the photic zone to the aphotic zone, is a submersible traveling from the surface of the ocean to the abyss.
What is aphotic zone and photic zone?Depending on the lighting, the waters are divided into:
PHOTIC ZONE → up to 200 m deep. DYSPHOTIC ZONE → between 200 m and 400 m deep. APHOTOTIC ZONE → below 400 m depth.With this information, we can conclude that a research expedition traveling from the photic zone to the aphotic zone, is a submersible traveling from the surface of the ocean to the abyss.

Scientists have observed that in the Antarctic ecosystem Adélie and Chinstrap penguin populations have decreased in the past 40 years by about half. However, Gentoo penguin populations have remained steady and are possibly increasing.
