Why are viruses to be nonliving
Answer:
Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
all of the cells in a persons skin liver heart and kidneys contain the exact same?
Answer:
no
Explanation:
Which stage of the cell cycle occurs after mitosis in which the cell creates a cleavage furrow.
Interphase
G2
Anaphase
Cytokinesis
Answer:
Anaphase
Explanation:
After anaphase, a cleavage furrow forms in the equatorial cortex in typical animal mitosis. To divide the two daughter cells, this furrow then progresses inwards.
The sister chromatids differentiate from each other in anaphase and are pulled toward opposite ends of the cell. The "glue" of protein that binds together the sister chromatids is broken down, causing them to separate. Each one now has a chromosome of its own.
We know that the formation of chemical bonds results in a release of energy. In the process of aerobic cellular respiration, the energy ________ from the formation of carbon dioxide and water is ________ than the energy needed to break the bonds in sugar and oxygen.
1. released, greater
2. absorbed, greater
3. released, less
4. absorbed, less

Explanation:
Which factor determines carrying capacity?
A. Species diversity
O B. Limiting factors
O C. Population density
O D. Feeding relationships
Answer:
D
Feeding relationship I guess
Answer:limiting factors
Explanation: limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.

If an atom contains one electron and one proton, will it carry any charge or not if not explain
Answer:
That atom will not contain any charge because one negative charge of single electron and one positive charge of single proton are neutralized by each other.

Plz help will mark brainlest plzzz thxx
Answer:
1. Gravitational potential energy is the energy that an object has because of its height and is equal to the object's mass multiplied by its height multiplied by the gravitational constant (PE = mgh). Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point.
2. Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared (KE = 1/2 mv2). Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.
3.Initially, before the big bang, the universe-ball was at rest. Now, after the big bang, it is falling: light and matter exist, and they are moving. And yet, because of the negative energy built into the gravity field created by these particles, the total energy of the universe remains zero.
4. When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
5. When the skater is dropped onto the ramp from above, the potential energy decreases and the kinetic energy increases. Every time the skater bounces from the impact, thermal energy is gained, and both potential and kinetic energy are lost.

explain why cells must divide rather than grow. explain how surface area and volume as well as transport across the cell membrane are related to cell size and homeostasis
Answer:
Cells must divide rather than grow in order to replace damaged cells and reproduce unicellular organisms. The surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. Along with this, cell transport helps cells maintain homeostasis by keeping conditions within normal ranges inside all of an organism's cells.

Recently, scientific researchers have been delving into how culture and human behavior are affected by our DNA. One field that studies genes is the field of epigenetics. Identify the correct description of what the field of epigenetics studies.
Answer:
the ways in which gene expression is influenced by a person's environment
Explanation:
Epigenetics may be defined as the field of study where one studies about the heritable changes in the gene expression which do not involve the changes in the underlying sequence of the DNA. It literally means above the genomes.
Scientist and researchers have delving into how human behavior and culture are affected by the DNA. Epigenetics is the study that correctly describes the ways in which the gene expressions are influenced by the individual's environment.

What would happen to the cycling of nutrients, including water, oxygen and carbon
dioxide, if plants died out on Earth?
Answer:
Water would become less used and more abundant, oxygen would be less produced, and carbon dioxide would become more abundant because the plants won't take it in to produce glucose.
When blood glucose levels are high and the glucose is not utilized for cellular respiration, the human body will store this glucose in the liver and muscles. In what form is this glucose stored?
Answer:

Explanation:
glycogen is a polysaccharide composed of many molecules of glucose. The liver turns glucose into glycogen through glycogenesis

Answer:
Materials like concrete can absorb very little energy, making them very suseptible to minor earthquakes.
The gene that codes for albumin protein in humans is 25,000 base pairs from the beginning of the protein coding sequence to the end of the protein. However, the mRNA for this protein is only 2100 base pairs long. What could account for the large difference
Answer:
RNA splicing
Explanation:
RNA splicing is the mechanism by which messenger RNA precursors (pre-mRNAs) are processed to generate mature mRNA transcripts in eukaryotic genomes. During RNA splicing, the non-coding regions of the pre-mRNA sequence (i.e., introns) are removed, while coding regions (i.e., exons) are joined together. In consequence, the resulting mature mRNA is shorter than the pre-mRNA. RNA splicing reactions are catalyzed by the spliceosome, an RNA-protein complex that removes introns from the pre-mRNA. After RNA splicing, the mature mRNA is used as template to produce a specific amino acid sequence, where triplets of RNA nucleotides (codons) in the mRNA are used to assemble specific amino acids in order to form a protein.

Why is the core of the earth solid, despite its extreme temperature?
Answer:
Pressure
Explanation:
The pressure from the other layers makes it impossible for any liquid to flow, but since it is getting pressed from all around, it is solid.

Number 12
Number 19
Number 16
Answer:
12) When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution
16) In other words, plasma membranes are selectively permeable—they allow some substances through but not others. ... The most direct forms of membrane transport are passive. Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement.
19) To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.
