Answer:
convergent plate boundary.
Explanation:
When they collide this is what is makes.
Answer:
d. With the direction of gravity
Explanation:
- Geotropism or gravitropism is a coordinated process of plant growth in fungi and plants to respond to the changing gravity. It a general feature that are found in higher and lower altitude plants.
- The roots show positive gravitropism and the stem negative gravitropism this they appear to be bend upside on a hill or slope. Can be seen with a potted plant, was the woody stems are capable of bending.
Trawling refers to the process of fishing that uses a fishing net through the sea water behind one or more boats. It is a common method of extraction of sea living resources.
It is the main cause of the degradation of the seabed which threatens the biodiversity. It kills a number of corals, sponges, fishes and the microflora on the seabed. Corals, particularly are damaged wouding the tissue and making them susceptible to infection. It also removes certain economically important sea weeds. The ocean sediments are disturbed causing the suspended solids to enter the seawater and causing turbidity affecting the penetration of sunlight. The suspended soilds can also cause growth of harmful algae causing algal blooms affecting the other biotic factors of the sea. The disturbance in the ocean sediments due to trawling causes the harmful pollutants like DDT that are trapped in the sediments reach the water column and enter the food chain of the living organisms.
Answer:
2) 25%
Explanation:
Let the traits for the black coat color be = BB
Let the traits for the brown coat color be = bb
Let the traits for heterozygous black coat color be = Bb
Now; the question says what is the probability of producing a rabbit with brown coat color from two rabbits that are both heterozygous for black coat color.
This implies that if two rabbits that are both heterozygous for black coat color cross together;
i.e Bb × Bb ;
The offspring will be (BB, Bb, Bb, bb)
BB (rabbits with black coat color) = 1/4
Bb (rabbits that are heterozygous for black coat color) = 2/4
bb (rabbit with brown coat color) = 1/4
Lets focus on ''bb'' ;
bb = 1/4 × 100%
= 25%
Answer: The aluminum atom loses electrons to form an ion.
The ion that is formed is <u>positive</u>
<u></u>
<u>Second Part of the question:</u> What is the name of the aluminum ion?
<u>
</u>Answer : <u>Al+3</u>
Explanation: <em>An aluminum ion has a charge of +3. It is not a neutral atom. It has a + charge, the electrons must have been taken away (electrons have a negative charge). Since the atomic number is 13, the number of protons is thirteen. In a neutral atom, there would be thirteen electrons. You take away 3. There is 10 electrons in Aluminum Ion. </em>
