Answer:
During respiration, most atp is formed as a direct result of the net movement of protons flowing through a channel
in all organisms, certain genes are expressed at any given time while other genes are not. both prokaryotes and eukaryotes regulate gene expression at the transcription stage. however, the greater complexity of eukaryotic cells makes it possible for gene expression to be regulated at many other stages as well. the diagram below shows different stages at which gene expression may be regulated in eukaryotes.
Answer:
The process of turning genes on and off is known as gene regulation. Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for examp
2 What is the function of proteins in the cell membrane?
F Facilitate the movement of particles across the cell membrane
G Receive chemical signals from other cells to begin a process in the cell
H Code for specific structures found in the cell membrane
J Create a hydrophobic layer that forms a barrier between the inside and outside of the cell
What organs help to complete digestion in the small intestine?
Answer:
The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion.
What is a Objective Summary on Global Warming?
Answer:
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
Explanation:
Answer:
The study, published last month in the journal Geophysical Research Letters, found that climate change is making summers hotter and longer, while shrinking the three other seasons. ... They found that over the nearly 60-year period, summers grew from an average of 78 to 95 days long
Where would you most likely find terrestrial communities with temperate deciduous forests?

3. Hydrogen peroxide is used as an antiseptic to kill bacteria in cuts and abrasions. Many of these are catalase positive, yet they are still killed by the actions of hydrogen peroxide. Why does this occur
Answer: Hydrogen peroxide is used as an antiseptic to kill bacteria in cuts and abrasions. Many of these bacteria are catalase positive,
Explanation: that’s it
1. Describe the flow of energy from the sun to a producer, like grass, and then to a consumer, like a rabbit. Type your answer here:
Explanation:
The Sun then provides energy to the grass through the process of photosynthesis. The rabbit eats the grass, and the rabbit absorbs its energy. Finally, the snake eats the rabbit, and it absorbs the rabbit's energy. Energy travels from the Sun and moves through the ecosystem with each consumer along the chain.
A mineral is defined as a natural substance that is neither animal nor plant, has a

B. solid substance or element that is essential to human nutrition.
C. naturally occurring, crystalline, inorganic solid that contains only one element.
D. naturally occurring inorganic solid consisting of chemical elements in specific proportions, whose atoms are arranged in a repeated internal pattern.
Answer:
the answer is A. specific composition and structure, and contains one or more silicon-oxygen tetrahedrons.
Explanation:
how are neurotransmitters and hormones similar and how are they different?
Answer:
Both neurotransmitters and hormones influence our thoughts and motivations, as well as our ability to learn and concentrate. However, neurotransmitters are short-lived while hormones act for longer periods of time.
What are the states of energy? List the Laws of Thermodynamics.
Answer:
The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium.
Explanation:
Which part of a neuron is most similar to other cells in the body?
dendrite
axon
glia
body
Answer:
D. The Cell Body
Explanation:
The cell body has genetic information, keeps the neuron's structure, and gives it the energy it needs to do things. A neuron's soma, like other cell bodies, has a nucleus and other special parts.

Where is the protective covering of the axon?
Answer: myelin sheath
Explanation:
The axon is covered by a myelin sheath. The axon passes information to the next neuron or other cell in the body. A myelin sheath.
how are plant and animal cells similar in structure
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
What are two things that compose matter?
Answer:
All matter is made up of atoms, which are in turn made up of protons, neutrons and electrons. Atoms come together to form molecules, which are the building blocks for all types of matter. so it is like they all come together to make a group then they work together
Explanation:
How does energy flow in an ecosystem
Answer:
Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level. Producers are always the first trophic level, herbivores the second, the carnivores that eat herbivores the third, and so on.Hope this helps you !!Write a title for each step of primary

explain the effect of germination on pea seed respiration
Answer:
"The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is higher because the cells are growing/going through mitosis which requires energy/ATP in order to be carried out which is generated through the process of cellular respiration."
