Answer:
False
Explanation:
The process of primary succession can take hundreds, if not thousands, of years. In contrast, the process of secondary succession can reestablish an ecosystem's climax communities in as few as 50 years. The ecosystem's animal populations are also established more quickly during secondary succession.
Hope this helps!

Answer: The correct answer is TRUE
Explanation: Primary succession takes hundreds to thousands of years, and secondary succession is much shorter.
The following genotypes of two independently assorting autosomal genes determine coat color in rats:
A—B—(gray); A—bb (yellow); aaB—(black); aabb (cream)
A third gene pair on a separate autosome determines whether or not any color will be produced. The CC and Cc genotypes allow color according to the expression of the A and B alleles. However, the cc genotype results in albino rats regardless of the A and B alleles present. Determine the F1 phenotypic ratio of the following crosses:
a. AAbbCC x aaBBcc
b. AaBBcc x AABbcc
c. AaBbCc x AaBbcc.

removal of forests for land development
three frogs jumped a total of 115 centimeters how far could each frog have jumped
Answer:
38.33 repeating
Explanation:
If the total was 115 centimeter all together and there were 3 frogs than you would want to divide the number by 3
115 centimeters divided by 3 is 38.33 repeating
if it is rounded just 38.3
or rounded to the nearest whole number it will just be 38

Over time, three types of cells derived from this single-celled animal have emerged with specialized functions and they interact as a multicellular organism.
Type 1: Launches the toxin-loaded vesicles. Non-motile
Type 2: Detects the toxin, moves, and hunts the prey.
Type 3: Engulfs the bacteria, breaks them down, and stores the parts. Non-motile
Required:
What organelles do each type have?
Answer:
Golgi bodies, endoplasmic reticulum and lysosomes.
Explanation:
Many vesicles are formed in the Golgi bodies and the endoplasmic reticulum, that is responsible for the transportation of materials from one part of the cell to another. Endoplasmic reticulum is the organelle that launches the toxin-loaded vesicles or in other words it is responsible for detoxification i. e. removal of toxic substances from the cell. Lysosomes is the organelle that act against the microorganisms such as bacteria , virus etc.

How do volcanic eruptions create rock?
Answer:
Once the Magma has cooled of it will turn into hard solid rock (or if you put cold water on it)
It has also created our different islands that we have today because of volcanoes.
Explanation:
Hope that helps
Answer:
magma is sometimes pushed up toward the surface, notably during volcanic eruptions. As it cools, the magma solidifies in the form of magmatic rocks such as basalt. So the rocks of Earth's crust are constantly being transformed as part of the geological cycle that lasts millions of years.

What is vega? A- Fusing hydrogen at its core B-It has lost its outer shell and only retained hot core that is slowly losing its brightness C- it’s temperature has decreased but it shining brighter than before
Answer: It is fusing hydrogen at its core.
Explanation: Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars.
At its core, it is fusing hydrogen. The explanation is that the centres of main sequence stars fuse hydrogen atoms into helium atoms.
What is Vega?The sun is one of the majority of main sequence stars, which make up about 90% of all stars in the universe.
Astronomers have spent a lot of time studying Vega, which has led to the claim that it is "arguably the next most important star in the sky after the Sun."
Around 12,000 BCE, Vega was the northern pole star; it will be again around the year 13,727 when its declination occurs. The first star other than the Sun whose picture and spectra were captured was Vega.
Therefore, At its core, it is fusing hydrogen. The explanation is that the centres of main sequence stars fuse hydrogen atoms into helium atoms.

Explanation:
Answer:
Cells make up tissues, tissues make up organs, and organs make up organ systems.
Explanation:
The cell is a fundamental component of all organisms. A group of cells that have the same structure and function make up a tissue. There are four types of tissues in our body: muscular, connective, nerve, and epithelial. Several types of tissue connect into an organ. The organs collectivley make an organ system. The 12 systems in the body are nervous, digestive, cardiovascular, muscular, skeletal, endocrine, urinary, immune, integumentary, respiratory, excretory, and reproductive.
