At mid-ocean ridges, new rock is formed from magma, which is essential for plate tectonics to continue.
Explanation:Mid-ocean ridges play a vital role in the dynamic process of plate tectonics. These underwater mountain ranges are located at divergent boundaries, where tectonic plates are moving apart from each other. At these locations, new rock is formed through a process involving magma.
Magma, which is molten rock beneath the Earth's surface, rises up from the mantle to fill the gap created by the separating tectonic plates. As the magma approaches the ocean floor, it encounters lower pressure, causing it to melt and form new rock. This process is known as decompression melting. The newly formed rock solidifies upon contact with the cold seawater, creating fresh oceanic crust.
Over time, this continuous cycle of magma rising, solidifying, and forming new rock contributes to the expansion of the seafloor. As new crust is generated at mid-ocean ridges, it pushes the existing oceanic crust away from the ridge in both directions, driving the movement of tectonic plates and influencing the shape and size of Earth's continents.

3. The goal of meiosis is to produce gametes, or sex cells for reproduction. Each
gamete will have?
Answer:
Each gamete will have half the number of chromosomes in a regular cell, so for humans, the sex cells will have 23 chromosome halves.
hope this helps :)
Final answer:
The goal of meiosis is to produce haploid gametes, each containing half the number of chromosomes as the parent cell. This ensures that upon fertilization, the zygote has the correct number of chromosomes. Variation is introduced during meiosis through processes like crossing-over and random chromosome alignment.
Explanation:
The goal of meiosis is to produce gametes, which are sex cells essential for reproduction. The process of meiosis involves two divisions, resulting in four haploid cells, each containing half the number of chromosomes compared to the original parent cell. These haploid cells ensure that when two gametes, such as a sperm and an egg, unite during fertilization, the resulting zygote has the correct number of chromosomes for the species, typically restoring the diploid state.
During sexual reproduction, the genetic material from two parents combines to create an offspring. The introduction of variation in the produced gametes is ensured by mechanisms such as crossing-over during prophase I of meiosis, where sections of DNA are exchanged between homologous chromosomes, and random alignment of chromosomes during metaphase I. Therefore, each gamete will have one set of chromosomes, which is half as many as those found in regular body cells.
In humans, for example, gametes contain 23 chromosomes, one from each homologous pair, making them haploid. This contrasts with the typical human body cells, which are diploid and contain 46 chromosomes. The production of gametes by meiosis is critical for maintaining the genetic continuity and diversity of sexually reproducing populations.

D) make and store energy
Answer:
A) move and capture food
Explanation:
Amoeba is madeup of single cell and having a true nucleus or membrane around the nucleus. Amoeba belongs to kingdom protista because it has some characteristics of animals such as it can move from one place to another. Amoeba used phagocytosis which is a type of endocytosis in which large substances are entered into the cell. Pseudopod is part of amoeba body which is responsible for the movement and capturing the food.

Which of the following is NOT a carbohydrate
Glucose
Sucrose
Glycine
Cellulose
Answer:
Glycine
Explanation:
Glycine is an amino acid, not a carbohydrate.
Glycine is not a carbohydrate. Therefore, option (C) is correct.
What are carbohydrates?Carbohydrates are one of the main classes of macronutrients that are essential for the human diet. They are molecules composed of carbon, hydrogen, and oxygen in a ratio of approximately 1:2:1, and are used primarily as a source of energy in the body. Carbohydrates are found in many foods, including fruits, vegetables, grains, and dairy products.
There are two main types of carbohydrates: simple and complex. Simple carbohydrates, such as glucose and fructose, are made up of one or two sugar molecules and are quickly digested and absorbed by the body. Complex carbohydrates, such as starch and fiber, are made up of many sugar molecules and take longer to digest, providing sustained energy.

Students treated a population of bean plants with fertilizer. They observed that these plants, on average, were taller than another population of the same kind of bean plants that were not treated with fertilizer. These observations lend support to which of the following conclusions?
A. Not all plants respond to fertilizer the same way.
B. Fertilizer can affect the growth of bean plants.
C. Survival of bean plants is dependent on fertilizer.
D. Only fertilizer can make bean plants larger.
Answer:
B
Explanation:
Because the excessive use of fertilizer can affect the growth of the bean plant
Final answer:
Observations where treated bean plants grew taller than untreated ones support the conclusion that (option B) fertilizer can affect bean plant growth.
Explanation:
Students observed that bean plants treated with fertilizer were taller on average than those not treated with fertilizer. This observation lends support to the conclusion that (option B) fertilizer can affect the growth of bean plants. While it is possible that not all plants respond to fertilizer in the same way, the data provided specifically shows that the treated bean plants were taller. This suggests that fertilizer has a positive effect on growth, at least for this type of bean plant. It does not, however, support the conclusion that survival is dependent on fertilizer or that only fertilizer can increase plant size, as this would require further testing and data.

Volume of Rectangular Prisms
A rectangular prism has a length of 14m, a height of 6m, and a width of 20m. What is
its volume, in cubic m?
Answer:
1,680 cm.
Explanation:
--> LxWxH.
--> 14x6x20.
Final answer:
To find the volume of a rectangular prism with dimensions of 14m in length, 6m in height, and 20m in width, you multiply these dimensions to get 1680 m³.
Explanation:
The question involves finding the volume of a rectangular prism. The formula to find the volume of a rectangular prism is to multiply its length, width, and height. Given a rectangular prism with a length of 14 meters (m), a height of 6 meters (m), and a width of 20 meters (m), the volume is calculated as follows:
Volume = Length × Width × Height
Volume = 14m × 20m × 6m
Volume = 280m × 6m
Volume = 1680 cubic meters (m³)
Therefore, the volume of the rectangular prism is 1680 cubic meters (m³).
