In 4-5 sentences, explain why it is important for our cells to undergo the cell cycle.

Answer: Scientists say that energy can neither be created nor destroyed, so therefore it is impossible for there to be an energy crisis.

Explanation:

I'm pretty sure I'm right

Answer:

There is a problem because if energy is created as machines worked everything would speed up until it breaks, and if energy was destroyed as machines worked everything would eventually slow down and stop. So in both cases the world would end, a whimper in one a bang in the other.

Explanation:

The correct answer is B. Traits or features that take effect.

Explanation

Property is a word to designate any quality that identifies identifying something or someone, distinguishing it from its peers. It can refer to different issues such as its characteristics, capabilities, possibilities, physical appearance, among others. According to the text, "There are biological properties of organisms that prevent breeding across different species". So the answer is B. Traits or features that take effect.

Answer:

1. In ecology and Earth science, a biogeochemical  cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic and abiotic compartments of Earth.

2. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds.

3. Heated by sunshine, the ground heats the air just above it. That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense. ... The air cools as it rises, and eventually clouds form.

Answer:

1) NADP is the reducing agent produced by the light reactions of photosynthesis and is consumed in the Calvin cycle of photosynthesis and used in many other anabolic reactions in both plants and animals.

3) Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes. There are two kinds of photosystems: photosystem I (PSI) and photosystem II 

● PhotosystemSII acts first during the light transformation process in photosynthesis.

● Photosystem1 is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from 

plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by carrier NADPH.

Answer:

a. the second nucleotide is wrong. It is a U but should be an A. No other nucleotides were effected by this, only the one was effected. This is a Point (Substitution) Mutation.

b. the third nucleotide is wrong. It is a T that was inserted. As you can see, the rest of the nucleotides are right, but since the T was added, it will mess up how the rest of the sequence is read. It will be read UAT GGC GAA... instead of UAG GCG AAU... see how it messed it up? This is an Insertion (Addition) Mutation.

c. the second nucleotide was deleted. This is called a Deletion Mutation. It will mess up the rest of the sequence, similar to how the example above did.

I hope that helped you understand!

Because the total of neutron and proton/electron is the atomic mass. So if you wanna find proton/electron and you know the neutron, just minus the atomic number with the neutrom and you will get the proton

Here if you need the formula

Atomic number = Total neutron + Total proton or electron

Answer:

The sulfur cycle describes the movement of sulfur through the geosphere and biosphere. Sulfur is released from rocks through weathering, and then assimilated by microbes and plants. It is then passed up the food chain and assimilated by plants and animals, and released when they decompose.

Not sure what the options are, but artificial selection would be when farmers/breeders choose only to plant/breed the organism with desired characteristics in order to cause the evolution of the trait while natural selection is when organisms that are better adapted to their environment usually survive and produce offspring, causing the evolution of their traits which help them to survive.

Answer: In Photosynthesis, carbon dioxide and water is yielded to glucose and oxygen. In respiration, glucose and oxygen is yielded to carbon dioxide and water. C6H12O6 (glucose) + O2(oxygen) → CO2(Carbon Dioxide) + H2O(water) + ATP energy. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

The ecosystem services are all the benefits provided by the ecosystem to human. Otion A) habitat for wildlife is not an ecosystem service.

When talking about ecosystem services, we are referring to the goods and services offered by ecosystems to human populations

There are different types of ecosystemic services:

These are the products obtained by nature to be used or consumed, directly or with previous processing.

Among them, we can mention food, clear fresh-water, fertile soils, geotic materials, raw materials (used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, and others.

Explanation:

Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

There is a supply of undeveloped eggs in the ovaries. At the beginning of the menstrual cycle, between 6 and 12 undeveloped eggs in the ovaries start to mature. A layer of cells grows around them. At around day 5 of the menstrual cycle, the biggest follicle will continue to grow for another week. At around day 14, the follicle breaks apart, and the wall of the ovary ruptures. The egg is released from the ovary into the fallopian tube, where it can get fertilized. This process is called ovulation. The uterus also changes during the course of the menstrual cycle. It has a lining of cells on the inside, kind of like a cushion with a lot of blood vessels. Fallopian tubes connect the ovaries and the uterus. The uterine cycle begins with menstruation. This is the process through which most of the lining and blood from the last uterine cycle are cleared out of the uterus to prepare for a new attempt at pregnancy. Starting at around day 5, the lining starts to grow. It builds back up to prepare a place for the egg to grow if it gets fertilized. After ovulation, the egg reaches the oviduct. If sperm cells have entered the vagina during intercourse, fertilization may occur at any time in the next two weeks. Then the fertilized egg will move into the uterus and implant itself into the lining, where development will begin.

The events in the menstrual cycle are primarily triggered by hormonal signals from the body. The menstrual cycle is a complex process regulated by the interplay of hormones produced by the hypothalamus, pituitary gland, and ovaries.

1. Hypothalamus: The hypothalamus, a region of the brain, releases gonadotropin-releasing hormone (GnRH) in a pulsatile manner. GnRH stimulates the pituitary gland.

2. Pituitary gland: In response to GnRH, the pituitary gland secretes two important hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH).

3. Follicular phase: At the beginning of the menstrual cycle, FSH stimulates the growth and maturation of ovarian follicles, which contain the developing eggs (oocytes).

As the follicles grow, they produce estrogen, a hormone that helps prepare the uterus for a possible pregnancy.

4. Ovulation: As the estrogen levels rise, it triggers a surge in LH production by the pituitary gland. The LH surge leads to the release of a mature egg from the ovary, a process called ovulation.

5. Luteal phase: After ovulation, the ruptured follicle in the ovary transforms into a structure called the corpus luteum. The corpus luteum produces progesterone, which prepares the uterus for potential implantation of a fertilized egg.

6. Menstruation: If pregnancy does not occur, the levels of estrogen and progesterone decline. This drop in hormone levels triggers the shedding of the uterine lining, resulting in menstrual bleeding.
