Explain the concept of growth using these terms: differentiate, meristem, elongation, and vascular cambium.

Answers

Answer: Well for one, Differentiate is when a cell matures and is used in a specific function. Meristem is a cell which never differeates and constantly divides so it is a mitotic cell. Elongation is the plant growing length wise therefore the meristem elongates the plant. Vascular cambium is the cambium which starts out in vascular bundles of the plant and then grows to form a ring inside the stem of plants that live for more than year- it causes and increase in thickness of the stem and branches.

why do fungi need to live in moist areas? A. they absorb water and nutrients through their filaments B. they are unable to photosynthesize C. they have a large surface area and dry out easily D. they can reproduce only asexually

Answers

Answer:

B

Explanation:

they are heterotrophic. This means that they rely on food from their environment to obtain energy.

They play an important role in decomposition. Fungi help catabolism of complex organic matter into simple available inorganic forms. In other words they breakdown organic matter to obtain energy. This process of decomposition requires aerobic ambient and moisture therefore they are mostly found in moist habitats rich in detritus.

Fungi need to live in moist areas because they have a large surface area relative to their volume, which makes them susceptible to drying out quickly in dry environments, which is option C.

What is a fungus?

Fungi are heterotrophs, which means they cannot make their own food like autotrophs (e.g., plants and algae) do, and instead, they obtain nutrients by absorbing organic matter from their surroundings. Fungi release digestive enzymes from their hyphae, which break down complex organic matter into simpler compounds that can be absorbed by the hyphae. To reach and break down sources of food, the hyphae need to grow and spread through the substrate (e.g., soil, wood, or another organism).

Hence, fungi need to live in moist areas because they have a large surface area relative to their volume, which makes them susceptible to drying out quickly in dry environments, which is option C.

Carbohydrates are the body's main source of energy. Without carbohydrates, your body will use up fat and protein in place of carbohydrates. These other sources of energy are harder to use. Carbohydrates provide energy for everything you do, whether it be running or breathing. Carbohydrates also provide important fiber for protection against disease. Extra carbohydrates (not used for energy), broken down as glucose, can be converted to glycogen, which is important for good muscle and liver health.

MARK me brainliest please and follow my page

If a nonnative species of squirrel is introduced into a forest, one of the things that can prevent it from reaching an invasive status is if the squirrel competes with stronger organisms for resources.

Competition is one of the factors that limit the growth of organisms' populations.

All other factors being equal, a combination of some of the following will make the squirrel attain an invasive status:

The absence of natural predators means that the squirrel's population is not threatened in any way.Low biodiversity in the forest ecosystem means that the squirrel will experience very little to no competition for resourcesReproducing quickly in the ecosystem means that the population will boom in no time.

[Anatomy, heart] The blood circulating through the heart muscle is called the cardiac circulation, which blood vessel does this system empty into that then leads into the right atrium? (Two words)

Answers

The heart pumps blood through the aortic valve into the aorta, the blood vessel empties this system, then into the right atrium where it flows to the rest of the body.

What is Aorta?

The aorta is defined as the largest artery of the body and carries blood away from the heart to the circulatory system which consists of several segments: the aortic root, the transition point where blood first exits the heart and functions as the water main of the body.

Blood leaves the heart through the aortic valve which then travels through the aorta forming a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles, and other cells.

Thus, the heart pumps blood through the aortic valve into the aorta, the blood vessel empties this system, then into the right atrium where it flows to the rest of the body.

you have learned that during a solar eclipse the moon passes between the sun and the earth. During a lunar eclipse, the earth passes between the sun and the moon. In this experiment you will simulate both a solar and lunar eclipse.


These supplies are needed:

A large ball about the size of a basketball to represent the earth
A small ball about the size of a tennis ball to represent the moon
A strong light of about 100 watts or more
A method for darkening the room

Note: If your room is difficult to darken, you may use the sunshine as a source of light. You may also want to use cardboard circles in place of balls. Cut one large circle about 8 inches in diameter to represent planet earth. Label it earth. Cut one small circle about 3 inches in diameter. Label it moon.

Procedure:

1. Place the large ball (basketball) about 12 feet from the light source. Then, place the small ball (tennis ball) in the shadow of the large ball. If you are using cardboard circles in place of the balls, hold the large cardboard circle up in the sunshine. Then, place the moon (small cardboard circle) in earth's shadow. When you have lined up the balls or cardboard in this manner, you have made a shadow fall on the moon. This shadow represents an eclipse of the moon.

2. Now, shift the balls or cardboard to make the shadow fall on the basketball or largest cardboard. In effect, the sun is being darkened. If you were an observer on the earth, this condition would be a solar eclipse. When the moon comes between the sun and planet earth, a solar eclipse occurs.

The preceding illustration shows how an eclipse can be artificially made. The moon (tennis ball) is darkened by a shadow. This shadow represents a lunar eclipse (moon eclipse). You can reverse the position of the tennis ball and the basketball to represent a solar eclipse.

What did you observe?

Answers

Answer:

A solar eclipse happens when the Moon passes between the Sun and Earth, casting a shadow on Earth that either fully or partially blocks the Sun's light in some areas. This only happens occasionally, because the Moon doesn't orbit in the exact same plane as the Sun and Earth do.

Explanation:

I am guessing in your experiment there, the ball had a complete shadow over it, to show you how a solar eclipse works or looks.

DNA replicates by which of the following models? a. conservative b. semiconservative c. dispersive d. none of the above

Answers

Meselson and Stahl were able to confirm that DNA is reproduced semi-conservatively based on the patterns of DNA labeling they saw.

How does DNA replication work conservative, liberal, or dispersed?

Because one strand of a newly created double-stranded DNA molecule will come from the original template molecule, DNA replication is a semi-conservative process. There will be a novel synthesis of one strand.

Which model of DNA replication is accurate?

The semi-conservative model makes the most sense on an intuitive level since the two strands can be separated into two templates, each of which has the entire information of the original molecule. Also, it ends up being the right choice (Meselson & Stahl 1958).

Which taxonomic group of land plants, still in existence today, was the dominant group of land plants when the angiosperms began their rapid increase in speciation and distribution?

Answers

When the angiosperms started their rapid expansion in diversification and range, the dominant group of terrestrial plants—the gymnosperms—was still in existence.

Gymnosperms predominated between 252.2 million and 66 million years ago, during the Mesozoic Era, giving origin to numerous of the modern families (Pinaceae, Araucariaceae, Cupressaceae). Gymnosperms dominated the environment in the early (Triassic) and middle (Jurassic) Mesozoic epoch. Gymnosperms had been eclipsed as the most common plant class in the majority of terrestrial biomes by angiosperms by the middle of the Cretaceous (approximately 100 million years ago). The increase in angiosperm variety that occurred throughout the Cretaceous epoch  led to the replacement and frequently extinction of gymnosperms and ferns.
