Answer:
Well I don't like killing things but lionfish are technically taking over the ocean since they are traveling everywhere and a hurricane caused six fish from an aquarium to accidentally get swept out into the Atlantic Ocean. Female lionfish produce thousands of eggs at a time, which has allowed their population to increase rapidly in the Atlantic. There’s no firm estimate of the number of lionfish in the Atlantic Ocean right now. However, it might be as many as 375 to 1,000 lionfish per acre of the ocean. These fish have predators such as sharks and scorpionfish in their natural habitat. However, they don’t have many natural predators in the Atlantic Ocean, where the typical predatory animals don’t seem to recognize lionfish as food, so it probably is ethical.
How doe water change the shape of earth surface?
Answer:
water is constantly moving across the earth. The water is strong enough to break down soil in tiny pieces. What’s happening is a process called erosion. Erosion is: the process of eroding or being eroded by wind, water, or other natural agents.
"the problem of soil erosion".
Water also carries sand and moves it around, this obviously changes the shape of the earths surface!

Which type of deposition creates sandbars? glacial river wave wind
Answer:
C / Waves
Explanation:
I took on exam got 100%
The type of deposition that creates sandbars is waves. Waves build sandbars far from shore, until they rise above the water's surface
What is sandbars?A sandbar or offshore Bar is submerged or partly exposed ridge of sand or coarse sediment that is built by waves offshore from a beach.
Deposition that creates sandbarsThe type of deposition that creates sandbars is waves.
As waves break, this pulls material from the shoreline, migrating further into the ocean. During heavy storms, large waves can build sandbars far from shore, until they rise above the water's surface.Thus, the type of deposition that creates sandbars is waves. Waves build sandbars far from shore, until they rise above the water's surface.

Answer:
Label A - G1 (growth phase)
Label B - S phase (DNA synthesis)
Label C - G2 phase (Growth and preparation for mitosis)
Label D - M phase (Mitosis - cell division)
Label E - Interphase
Explanation:
Label A refers G1 phase - In this phase metabolic changes occurs in the cell and cell get prepare for cell division. The cell grow in size only and moves into the S phase.
Label B refers S phase - In this phase DNA synthesis occurs in which genetic material replicates and form two sister chromatids in each chromosome.
Label C refers G2 phase - All the metabolic changes occurred prepare for mitosis and cytokinesis.
Label D refers M phase - In this phase, Mitosis occurs in which nuclear division and cell division (cytokinesis) takes place.
Label E refers to interphase - All the stages from G1 to G2 phases come under the interphase of cell division.
Hence, the correct answers are:
Label A - G1 (growth phase)
Label B - S phase (DNA synthesis)
Label C - G2 phase (Growth and preparation for mitosis)
Label D - M phase (Mitosis - cell division)
Label E - Interphase

Organisms’ characteristics can be used to determine the evolutionary relationships among them. The more closely related two organisms, the more characteristics they have in common. These shared characteristics, along with the fossil record, indicate that organisms have evolved over time from a common ancestor.

A dihybrid cross is created from plants that are heterozygous for both round seeds and yellow seed color. What is the ratio of offspring that have round seeds and yellow seed color?
Answer:
9:16
Explanation:
The ratio of offspring that have round seeds and yellow seed color in a dihybrid cross is 9 out of 16.
WHAT IS A DIHYBRID CROSS:A dihybrid cross is a cross between two individuals that are are heterozygous for two genes. In this question, a gene involving seed color and seed shape is used. The allele for round shape (R) and yellow seeds (Y) are dominant over wrinkled (r) and green seeds (y).A cross between two dihybrid i.e. RrYy × RrYy will result in the following offsprings:
R_Y_ - 9R_yy - 3rrY_ - 3rryy - 1Therefore, the ratio of offspring that have round seeds and yellow seed color in a dihybrid cross is 9 out of 16.
