Answer:
Both release carbon into the atmosphere.Explanation:
Diffusion is the process whereby gases move from an area of high pressure to low pressure. This includes- Internal respiration - this is the movement in the internal tissues between cells and capillaries, and - External respiration - when gas is exchanged between the alveoli and lung capillaries. Perfusion refers to the blood flow to tissues and organs. Alveoli are perfused by capillaries so the diffusion of oxygen and carbon dioxide can take place.
Answer: Both release carbon into the atmosphere.

Why do the temperatures change over the months?
O A. Because the Moon is tilted on its axis, it reflects more sunlight on Earth during different times of Earth's yearly orbit.
B. Because the Sun is tilted on its axis, parts of Earth get more sunlight during different times of Earth's yearly orbit.
O C. Because Earth is tilted on its axis, the stars reflect more light during different times of the Earth's yearly orbit.
D. Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit.
Answer:
Answer
Explanation:
B because the more the sun is titled the more heat=different season.
Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit. As Earth orbits around the Sun, its axis is tilted at an angle of about 23.5 degrees. Hence the correct option is D.
Why do the temperatures change over the months?The temperatures change over the months primarily because of Earth's axial tilt. As the Earth rotates around the sun, the angle at which sunlight hits different parts of the Earth changes.
This is because the Earth's axis is tilted about 23.5 degrees relative to its orbit around the sun. When a particular hemisphere is tilted toward the sun, it receives more direct sunlight, resulting in warmer temperatures.
Conversely, when that hemisphere is tilted away from the sun, it receives less direct sunlight, resulting in cooler temperatures. This cycle repeats itself annually, causing changes in temperatures over the months.
Hence the correct option is D.

Explanation:
In 2-3 sentences, explain how crossing over and independent assortment in sex cells affect the appearance of the fully developed organism.
Answer:
Explanation:
Crossing over and independent assortment in gametes (sex cells) can lead to genetic variation in the DNA of these gametes and lead to offspring looking different from their parents. Crossing over is the exchange of DNA between a pair of homologous chromsomes (the mom and the dad) which results in recombinant chromsomes that have new combinations of genes. Independent assortment refers to the lining up of chromsoomes along the metaphase plate in meiosis 1, and this can lead to different combinations of gametes.

Name 3 stages of cell division, and give a brief description of what happens in each stage? please help I really need some help with this much appreciated
Answer:
Prophase
- Mitosis begins with prophase, during which chromosomes recruit condensin and begin to undergo a condensation process
Metaphase
- Next, chromosomes assume their most compacted state during metaphase, when the centromeres of all the cell's chromosomes line up at the equator of the spindle
Anaphase
- The progression of cells from metaphase into anaphase is marked by the abrupt separation of sister chromatids. Two separate classes of movements occur during anaphase. During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the second part of anaphase, the spindle poles separate as the non-kinetochore microtubules move past each other
Answer:
the 3 stages are: Interphase, Mitosis, Cytokinesis
Explanation:
Interphase is the phase of the cell cycle in which a typical cell spends most of its life. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions.
Mitosis: a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Cytokinesis: The cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
organize at least seven of your body's cell processes that require energy
Answer:
search up the question and you find lots of accurate results
Energy is required for a variety of vital biological and cellular functions, including ATP hydrolysis. These include active transport, Purinergic signaling, synaptic signaling, intracellular signaling, DNA and RNA synthesis, and muscular contraction.
What do you understand by cell ?
The fundamental units of all living things are cells. There are many billions of cells in a human body. They provide the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks.
Adenosine triphosphate molecules directly provide the energy needed for cellular functions (ATP). One adenosine molecule and three phosphate groups, or Pi for short, make up ATP. The chemical energy that is stored in each ATP molecule is not very large. By dissolving ATP into adenosine diphosphate (ADP) and a phosphate group, this energy may be released.
The energy process include active transport, Purinergic signaling, synaptic signaling, intracellular signaling, DNA and RNA synthesis, and muscular contraction.

Is DNA replication always a foolproof process? Explain your answer.
Answer: No. Although many proteins check the DNA for damage or errors, damaged regions can still be replicated. This may result in gene alterations and serious complications for the organism.
Explanation:
No, replication is not always a foolproof process although many proteins look for DNA damage or mistakes, damaged areas can still replicate. This can lead to gene rearrangements and serious problems in the body.
Some mutations are caused by mistakes in DNA replication. DNA replication isn’t always 100% complete. Sometimes, an incorrect base is inserted into the new DNA strand. This incorrect base can become permanent.
Breaks in DNA are caused by DNA replication errors, particularly those in regions that are difficult to replicate, known as fragile sites.
Breaks in DNA can cause cancer, mainly because they increase the risk of chromosome fragments rearranging themselves and activating genes that cause uncontrolled cell division.

Answer: 3 and 5 only
Explanation:
Adenine is a purine nitrogenous base and it pairs with thymine which is a pyrimidine nitrogenous base with a triple hydrogen bond in a DNA structure. The adenine binds with thymine directly and indirectly with a deoxyribose sugar which is attached with it in the back it forms the part of sugar phosphate backbone and in the front hydrogen bonding helps in the stabilizing the DNA structure by binding two separate strands of DNA in a stable double helical structure.

Compare the Three General patterns of population dispersion
Answer:
Explanation:
There is Uniform dispersion, where the individuals in a population are more or less evenly distributed. Also, there is Random dispersion in which individuals are distributed randomly, meaning there is no plan. Finally, there is Clumped dispersion, where individuals are just distributed in groups. Hope it helps x.
The three general patterns of population dispersion are as follows:
Clumped: Variance/mean is greater than 1.Random: Variance/mean is equal to 1. Spaced: Variance/mean is less than 1. What is Population dispersion?Population dispersion may be characterized as the process of spatial distribution and arrangement at any particular moment of the individuals of a certain species. It generally governs the spacing of individuals with the environment at a given time.
Clumped type is the most common type due to attraction. In a random type, the facts of attraction or repulsion do not favor. Spaced type of population dispersion is also known as uniform.
It is generally present in artificial ecosystems or cultivation. Uniform patterns of dispersion are generally a result of interactions between individuals like competition and territoriality.
Therefore, the three general patterns of population dispersion are well described above.
