What is the answer to everything hypothetically?
Which of the following is transported throughout the body by the circulatory system?
Please answer!!
Read the paragraph from the section "Types Of
Isolation."There are biological properties of organisms
that prevent breeding across different species. They are
known as reproductive isolating mechanisms (RIMs). A
mechanism is a process or method. Which option is the
BEST definition of "properties" as it is used in the
paragraph above?
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.

How are fern sporophytes and moss sporophytes different?
Answer
The main difference between mosses and ferns is the presence or absence of a vascular system.
Explanation:
The gametophyte is prominent is mosses, but the sporophyte is prominent in ferns. The sporophyte of ferns is differentiated into true leaves, stem, and roots. In contrast, mosses lack true leaves, stem or roots.

Maintaining blood glucose levels is an important homeostatic activity of the body, not specifically because every cell of the body must have glucose but primarily because the brain relies on glucose for its metabolism.
a. True
b. False
Answer:
a. True.
Explanation:
Even though the cells in our body rely on glucose as a source of energy, they can replace glucose's energy with lipids or proteins' energy. In the brain's case, this is not possible since the blood-brain barrier, which is a highly selective barrier between the blood and the extracellular fluid in the central nervous system, allows the passage of glucose as the only source of energy. This is why maintaining the correct levels of glucose is crucial for the metabolism in the brain.
What happened to North American coastal waters when the great white shark population decreased
If North American coastal waters when the great white shark population decreased then planktivore fish number increases.
What happens to marine systems when shark numbers decline?In the Ecosystem, the spatial controls and abundance, sharks indirectly maintain the seagrass and corals reef habitats. The loss of sharks has led to the decline in coral reefs, seagrass beds and the loss of commercial fisheries.
Thus, the number of planktivore fish increases.

What can you conclude about starch, glucose and their movement across the Visking tubing? , What implications does this have for starch and glucose in the small intenstine?
Answer:
Starch molecules is too large therefore cannot pass through pores of visking tubing, glucose molecules is small enough to pass through pores of visking tubing. Visking tubing is like small intestine in this experiment, where starch is too large to be absorbed through small intestine into bloodstream, glucose is small enough to diffuse through small intestine and to be reabsorbed into bloodstream.
Which of the following is an example of selective breeding?
A. Breeding tomatoes to increase fruit size
B. Crossing 2 plants w desirable traits
C. Inserting genes from one plant into another
D. Returning bred plants to their natural habitat
Answer:
b
Explanation:
they chose the best tomatoes to make even better ones
Breeding tomatoes to increase fruit size is an example of selective breeding. Therefore option A is correct.
Selective breeding, also known as artificial selection, involves the intentional breeding of plants or animals to promote desired traits. The process typically involves selecting individuals with specific characteristics and breeding them to pass on those traits to the next generation.
In the given options, breeding tomatoes to increase fruit size is an example of selective breeding. By carefully selecting tomato plants with larger fruits and allowing them to reproduce, breeders can gradually enhance the fruit size of future generations.
This process relies on natural genetic variation within the tomato population and human intervention to guide the breeding process toward the desired outcome.

The preparation of the soil by mechanical agitation such as digging, plowing, overturning, and other ways, in agriculture for the purpose of plantation and cultivation of crops.
Disadvantageous of Tillage:
causes an eventual loss of soil production.accumulating pollutants in topsoil due to the movement of the components present in the soil.Increases in erosion rates due to loose soil.The destruction of earthworm pathways and root channels leads to a decrease in the quality of the soil.Thus, the correct answer is - option. increase erosion

PLEASE HELP! (c) Complete the table to represent the relationship between volume and surface area of a spherical structure surrounded by a membrane.
Answer/Explanation:
Recall:
Volume of a sphere = ⁴/3πr³
Surface Area = 4πr²
✔️For radius (r) = 1 mm:
Volume = ⁴/3 × π × 1³ = 4.19 mm³
Surface Area = 4 × π × 1² = 12.57 mm²
Ratio of volume to surface area = 4.19 : 12.57 = 1:3
✔️For radius (r) = 3 mm:
Volume = ⁴/3 × π × 3³ = 113.1 mm³
Surface Area = 4 × π × 3² = 113.1 mm²
Ratio of volume to surface area = 113.1 : 113.1 = 1:1

Light waves are a type of electromagnetic wave.
The wavelengths of light range from 400 nm to 700 nm.
Light waves are transverse waves
• The speed of light is 3 x 108 m/s.
Which statement can be inferred from the data?
O Light waves can transport matter through mediums and empty spaces.
O Light waves transmit energy by compressing the particles in mediums.
O Light waves can travel with and without mediums.
O Light waves transfer the particles of mediums in the direction of travel.
Answer:
Light waves can travel with and without mediums.
Explanation:
Light waves are a type of electromagnetic wave. Some of the characteristics (properties) of light waves include;
I. The wavelengths of light range from 400 nm to 700 nm.
II. Light waves are transverse waves.
III. The speed of light is 3 x 10^8 m/s.
Therefore, from the aforementioned characteristics it can be inferred that light waves can travel with and without mediums.
This ultimately implies that, light wave is an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
