Heat energy is transferred through solids, liquids, and gases. How is heat transferred throughout the world’s oceans?
Answer: Radiation, convection, and turbulent heat exchange, as well as evaporation and condensation of water vapor above the ground or ocean, transfer heat between the sea or ocean's surface and the atmosphere.
Explanation:
A skeleton is found that has a narrow pelvis, large occipital protuberance, and a sloping forehead. Is the skeleton a biological male or female? Justify your answer with an explanation on how you came to your conclusion.
(Forensics)
Answer: Male
Explanation:
The pelvis is narrow in males, the pubis arch is 90 degrees in angle. It is broad in case of females to support pregnancy and child birth. Also the pubis arch is more than 90 degrees in angle. An occipital protuberance is a region that connects the head to the neck and it is generally larger in males than in female. In males the forehead is sloping in the cranium whereas that in females it is vertical and flat.
Hence, the skeleton have the features that can be indicated towards the features of a male.
Explain how the disruption can disturb the cycling of carbon ?
Answer:
Humans have breached this cycle by digging up fossil fuels and burning them, leading to carbon dioxide building up in the atmosphere faster than natural systems can soak it up. This has led to a net increase in greenhouse gases in the atmosphere, causing the planet to heat up.
Explanation:
according to the passage an advantage of selective breeding is
The advantage of selective breeding is the ability to produce offspring with more desirable traits. Therefore, option A is correct.
What is selective breeding?Choosing parents with specific traits to breed with one another in order to generate kids with more desired traits is known as selective breeding. For thousands of years, humans have carefully bred a variety of animals and plants, including crop species that produce more.
Through artificial selection, several fruits and vegetables have been enhanced or even created. For instance, selective breeding was used to create broccoli, cauliflower, and cabbage from the wild mustard plant.
offspring can be produced with more desirable characteristics by selective breeding. Therefore, option A is correct.

what is produced by mitosis?
When a parent cell splits to create two identical daughter cells, the process of the nuclear division known as mitosis takes place in eukaryotic cells.
What is meant by mitosis?
DNA, a molecule found on chromosomes, is the genetic information carrier. They are linearly arranged genes that are present in couples in the cell's nucleus. Genes also are arranged in pairs, and each pair produces a coding that results in the production of a distinct protein.
Mitosis is a sort of cell division that makes sure each new daughter cell formed when a cell splits possess the same genomic structure.
Two cells referred to known as daughter cells are created during mitosis. Any newly formed daughter cells must have genetic material that is similar to that of the parent cell, and the number of chromosomes must stay constant.
Therefore two identical daughter cells are produced as a result of mitosis.

Explain the various phase of menstrual cycle with reference to changes in ovary and uterus and hormonal cycle.
Answer:
In the follicular phase, the follicles grow inside the ovary. The ovulatory phase is the time of greatest fertility for women. In it, estrogen levels peak just before the egg is released. In the luteal phase, after ovulation the follicular structure that remains in the ovary reorganizes and becomes a gland known as the corpus luteum. The self-determined life of the corpus luteum causes it to degenerate after 14 days and end a menstrual cycle. At the end of the luteal phase, progesterone and estrogen levels drop and menstruation occurs.
Explanation:
The follicular phase is where follicles develop (fluid-filled cavities in the ovary that contain an undeveloped egg) that will eventually house the egg. For the development of follicles, the body sends a signal to the brain to start the production of follicle stimulating hormone (FSH), the follicles begin to develop and produce estrogen. In the ovulatory phase, the level of estrogen in the body continues to rise, causing a rapid rise in LH. This increase causes the secretion of proteolytic enzymes that will degrade the follicular tissue allowing the maturation process of the ovum and its release to finish, a fact known as "ovulation". Ovulation usually occurs between 24 and 36 hours after the LH surge, so luteinizing hormone is a good factor for measuring the period of maximum fertility and knowing the fertile days of the woman. In the luteal phase, the corpus luteum develops that will last until a possible pregnancy or menstruation occurs, starting the next cycle. The egg, after being released, travels through the fallopian tube to the womb. It can survive up to 24 hours and sperm up to 5 days inside the uterus, therefore the days before ovulation and the day of ovulation itself, which can be calculated with the ovulation calendar, are those of maximum fertility and higher chances of pregnancy. After ovulation, the follicle begins to contract but continues to produce progesterone and begins to produce estrogen in order to continue preparing the uterus to receive the embryo.

An object at rest will ____________________ if no outside forces are applied
A. stay at rest
B. increase velocity
C. decrease mass
Answer:
A. Stay at rest
Explanation:
Since no other forces are applied to the object, there is nothing that can move the object since the forces are balanced.
Answer:
A. stay at rest
Explanation:
This is true because for example if a feather is left alone it will not move but if an outside force such as your hand or the wind applies force on it it will move.

hypothesis stated: the density of a liquid affects properties and how it interacts with other liquids.
How does density affect the position of a liquid relative to other liquids?
Answer:
The density of a liquid is shown by the object sinking or floating. Therfore, using this information if the object sinks then the object is more dense than the object that floats. When it comes to the density of liquids if the liquid sits on top of the water and does not mix, the liquid is less dense than water. If the liquid sinks into the water and the water sits on top, the liquid is more dense than the water.

Which is NOT true of the purpose of the alcohol in Gram staining?
A. It binds the crystal violet into the cell wall.
B. It decolorizes the cells.
C. It dries out the cells.
D. It shrinks the cell wall.
Answer:
the answer to this question is a
The statement which is not true of the purpose of the alcohol in Gram staining is as follows:
It binds the crystal violet into the cell wall.Thus, the correct option is A.
What is Gram staining?Gram staining may be defined as a methodology that is utilized for the classification of bacterial species such as gram-positive and gram-negative.
In gram staining, ethyl alcohol or acetone is used as a decolorizer that dehydrates the peptidoglycan layer. It involves the shrinkage or tightening of the cell wall.
In this process, the large crystal violet-iodine complex is not able to puncture this tightened layer of peptidoglycan.
Therefore, the correct option for this question is A.

Explanation:
Suggested evidence of natural selection at work in humans is the observation of Select one: a. low hemoglobin levels despite high elevation in Tibetan populations over generations b. increase in hemoglobin level when the average person travels from low to high elevation c. an increase in body fat in preparation for winter months at high elevation d. increase in muscle mass from extensive weight training over several months e. mountaineers using oxygen tanks when climbing at high altitude
Answer:
a. low hemoglobin levels despite high elevation in Tibetan populations over generations.
Explanation:
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
A suggested evidence of natural selection at work in humans is the observation of low hemoglobin levels despite high elevation in Tibetan populations over generations. This is as a result of a low level of oxygen in the blood of a living organism such as humans.
