Part 1: Which process does arrow F represent?
Part 2: Explain how matter is conserved during the process.
Part 3: Justify why this process is a recycling of carbon in the carbon cycle.
Use complete sentences to explain your answer.
Answer: Process F represents photosynthesis,
The AMOUNT of oxygen and carbon atoms released by photosynthesis are EXACTLY EQUAL to the atoms of these materials contained in carbon-dioxide converted.

Explain how diffusion is used to support the life processes of animals.
Answer:Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow.
Explanation:Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products. This table shows examples of substances required by cell and associated waste products.
where do women settlements flourish
Answer:
Favorable geographic as well as environmental conditions.
Explanation:
Human settlement flourish at that place where favorable geographic as well as environmental conditions are available such as availability of water , a suitable climate, fertile land etc. these resources attracts human to settle there due to availability of basic needs. If these natural resources are not present in a location so people does not came to settle there.

true
false
Answer:
TRUE
Explanation:
bacteria can also disrupt homeostasis in your body, and can make you sick. Any substance that causes the disease is called a pathogen. Your body reacts to pathogens to try and maintain homeostasis, and certain symptoms will appear as your body tries to get back on track.
Does the distance from earth to sun determine the seasons? please explain
Answer:
nope
Explanation:
Contrary to popular belief, the seasons are not determined by the earth's distance from the sun. The seasons are actually caused by the earth's tilted axis. Because the axis is tilted, when the Northern Hemisphere is tilted towards the sun, it's warm.

pls help me I need a answer asap
Answer:
The correct order is -
a. 5 > 3 > 4 > 1 > 2 .
Explanation:
In sedimentary rocks, the bottom layer of the rock form initial and the fossils found in them would be older and the layer on top deposited the latest so the fossils found in the top layer would be the youngest.
Newer layers form or deposited on the layers of the oldest or bottom layer of the sedimentary rocks. Hence, the fossils present in the bottom layer would be the oldest fossil and newer fossils will be above them and the youngest would be top.
Thus, the correct answer is - a. 5 > 3 > 4 > 1 > 2 .
One difference between gene mutation and chromosomal mutation that
Answer:
c. A chromosomal mutation can change the total number of chromosomes in the cell.
Explanation:
A gene mutation affects a single gene, and replication error is the main cause of gene mutation. A chromosomal mutation affects one part of chromosome or full chromosome. error in meiosis is the main cause of chromosomal mutation. Both mutations are responsible for a change in DNA. A chromosomal mutation leads to the change in total number of chromosomes in the cell.

Explanation:
During which phases of the cell cycle are chromosomes composed of two chromatids?
Answer:
The correct phases are S phase, prophase, anaphase.
Explanation:
The cell cycle, the sequence of events spanning the period from the completion of one cell division to the end of the next division, involves both the division of the cell nucleus (karyokinesis) and the division of the cytoplasm (cytokinesis). S phase, the next section of the interface, is marked by a dramatic increase in DNA synthesis and the synthesis of histones which are major cellular proteins bound to DNA. The cell is preparing for the start of mitosis. Chromosomes duplicate lengthwise, and each chromosome consists of two identical "chromatids."During prophase, the degree of packing of the chromatin increases, so the chromosomes become shorter and thicker and the centromeres begin to become visible. Each of the chromosomes, due to its duplication in S phase, is made up of two identical chromatids, called sister chromatids. Anaphase is the short phase, the sister chromatids begin to separate and migrate to the poles. Once the two chromatids separate, each is called a chromosome.

Pls help meee I will mark ❤️❤️❤️❤️
Answer: 1. Oxygen is used by cells to make energy.
2. Lungs, pharynx, larynx, trachea, bronchi, and diaphragm.
3. Blood carries oxygenated blood to the body and deoxygenated blood back to the lungs.
4. Increased amount of carbon dioxide lowers the pH of blood. Brain sends signal to the diaphragm to increase activity to get rid of carbon dioxide.
5. In the alveoli, oxygen and carbon dioxide move from high concentration to low concentration (this is also known as diffusion)
Explanation: Good luck! :D
Identify the two main processes through which carbon is cycled between the
atmosphere and living things.
Identify the main places carbon is stored.
Answer:
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them.

A population of wolves migrate North in search of food. As the wolves travel they enter a region that has long, snowy Winters. This makes them better able to sneak up on prey.
A.) Give two reasons that the population is not a Hardy Weinberg equilibrium.
C.) How are the allele frequency change in the wolf population
Answer:
A, This is the case of selective pressure of environmental factors like snow, due to which favored the expression of the allele that formed white coat phenotype. This is not a Hardy-Weinberg principle, in which no selective pressure is applied. The relative frequencies of the alleles change in the gene pool, due to selective pressure, and the expressed alleles are often significant for survival in those conditions.
b,HW equilibrium means no selective pressures like the long, snowy winters selectively favoring the white coat phenotype over the other coat phenotypes. Selective pressures change the relative frequencies of the alleles in the gene pool. It also means the population does not have either immigration or emigration to change the ratios of alleles in the gene pool The Hardy-Weinberg principle of genetic equilibrium tells us what to expect when a sexually reproducing population has no selection pressure, no gene flow, no nonrandom mating, not even genetic drift.
