How are humans circulatory system similar and different to other animals
Answer:
Humans have a heart with two atria and two ventricles that pushes blood in one direction. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle or a cardiovascular system that can push blood in two directions.
Humans circulatory system is similar due to presence of artrium and ventricles and different to other animals due to number of heart chambers.
How human circulatory system similar and different to other animals?Humans have a heart with two atria and two ventricles that prevents bactward flow of blood. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle that can push blood in two directions.

Suppose if all the bones of the skull (facial bones) are fused together, which function would you not be able to carry out?
Answer:
to masticate food
Explanation:
In adults, all the bones of the skull, except one, are fused together by immovable joints referred to as sutures. The sutures are fibrous joints which hold the bones of the skull together to form a rigid and strong structure that protects the brain. Skull bones fuse around two-years (18 to 24 months after birth). The only skull bone that is not fused by sutures in adults is the mandible, which is used to masticate food.

The Rock Cycle is happening all the time on Earth.
Some processes of the Rock Cycle take a long time.
O All rocks were once Metamorphic Rocks.
O Most rocks on Earth are Igneous Rocks.
Answer:All rock were once metamorphic rocks
Explanation:
Melted rock deep inside Earth forms igneous rocks. Sand, silt, plant and animal skeletons make sedimentary rocks. Heat and pressure underground convert rocks into metamorphic rocks. Therefore, option (C) is correct.
What is rock cycle?The rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the various applications of heat and pressure over the course of time. Igneous rocks are rocks that are formed by volcanic eruptions, while metamorphic rocks are formed when heat and pressure are applied to preexisting rocks. Shale, a type of sedimentary rock, can be transformed into slate with the use of heat and pressure, for instance.
The rock cycle is an important component of our dynamic Earth because it allows rocks to shift from one type of rock to another based on their location and circumstances. It recycles rocks to build new structures when plate tectonics changes the Earth's surface.

What happens to most of the sunlight
energy that reaches the earth?
Answer: In explanation
Explanation:
Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.

Usable fresh surface water is relatively scarce. To many people, streams and lakes are the most visible part of the water cycle. Not only do they supply the human population, animals, and plants with the freshwater they need to survive, but they are great places for people to have fun.
Answer:
True.
Explanation:
Usable fresh surface water is scarce. Freshwater is not in excess on our planet. We can find it on lakes, lagoons, rivers, and swamps, but it is only 3% of the totality of Earth's water. The importance of this water is that it is the one that is suitable for humans, a large number of plants, and animals. This is why there are different methods to store and distribute fresh water amongst all the population and places that need it. Besides, the places where freshwater is, are great for activities, such as swimming, sailing, rafting, diving, fishing, etc.
Since freshwater is scarce and has so many uses, we must take care of it.

b. Review and master the procedure in using the thermometer
c. Review the procedure in using a psychrometer
d. Review the procedure in using a refractometer
Answer:
a. Recall and master the procedure in using a salinometer
Explanation:
Salinometer, which is also known as salimeter is a laboratory equipment used to measure the salinity of a solution. Salinity refers to the concentration/amount of salt in a solution.
According to this question, a student was instructed by his/her teacher to measure the salinity of brine used in curing fish. This means that to do this, the student will have to make use of a SALINOMETER. In order to use the salinometer, the student has to recall and master the procedure in using a salinometer.

Two parts of the food chain are described below:
Part #1: These organisms are the ending of the food chain.
Part #2: This passes energy to plants and animals.
Which statement is true about these two parts of the food chain?
A) Part 1 are consumers, Part 2 is the sun
B) Part 1 are consumers, Part 2 are producers
C) Part 1 are producers, Part 2 is the sun
D) Part 1 are producers, Part 2 are consumers
(DONT ADD ANY LINKS)
The correct statement is B) Part 1 are consumers, Part 2 are producers.
What are the two parts of food chain?Part 1 of the food chain describes organisms that are the end of the food chain, which would typically be consumers or animals that feed on other organisms, including plants and other animals.
Part 2 of the food chain refers to something that passes energy to plants and animals. This is typically the sun, which provides energy through photosynthesis to producers, or plants, that convert light energy into chemical energy stored in food. Producers form the base of the food chain, providing energy to all other organisms in the ecosystem through the food they produce.

Answer: process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other
Explanation: sperm cells
CROSSING OVER:
Crossing over is a unique process that occurs only during meiotic division. Crossing over, also called recombination, occurs during prophase I of meiosis. Crossing over is the process by which non-sister chromatids of homologous chromosomes (a pair of similar but non-identical chromosomes from each parent). Crossing over ensures genetic diversity in the gametes (daughter cells) produced from meiosis:MEIOSIS:
Meiosis is the type of cellular division employed by sexual reproducing organisms to create sex cells or gametes. Meiosis produces four genetically different daughter cells called gametes. Sperm cells are gametes produced by male organism while egg cells are gametes produced by female organisms.Learn more: https://brainly.com/question/18824252?referrer=searchResults

how does it make you feel to know you have likely eaten a genetically modified food?
Answer:
Feels kinda weird knowing that we are eating not organic food but modified. Tastes a bit different.
Explanation:
A mutation is least likely to affect a cell when the mutation --
A mutation is least likely to affect a cell when the mutation is silent in nature or is not associated with an exon, it is least likely to affect a cell. Any mutation that happens to the introns does not affect the cell's function.
What is the function of cells and mutation?As genetic materials, nucleic acids encode information about the cell's structure and function, its proteins, receptors, and so on. The mRNA that is formed from the gene has roles in the formation of the receptor, the enzymes, etc., so if any mutation happens to the gene that is in the coding region, then it can show its impact, but if the mutation is of the silent type, then it has no impact on the cell.
Hence, when a mutation is silent in nature or is not associated with an exon, it is least likely to affect a cell. Any mutation that happens to the introns does not affect the cell's function.
