PLEASE HELP PLEASE What Is True About Smooth Muscle Cells?

Answers

Answer 1

Smooth muscle, also called involuntary muscle, muscle that shows no cross stripes under microscopic magnification. It consists of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike striated muscle, contracts slowly and automatically.

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?

Answers

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.

PLEASE HELP! (c) Complete the table to represent the relationship between volume and surface area of a spherical structure surrounded by a membrane.

Answers

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

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

Answers

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

Answers

"If the sharks disappear, the little fish explode in population, because nothing's eating them," Daly-Engel told Live Science. "Pretty soon, their food — plankton, microorganisms, little shrimps — all of that is gone, so all the little fish ultimately starve."

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.

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

Answers

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.

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.

Answers

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.
