Answer:the tough outermost membrane enveloping the brain and spinal cord
Explanation:
Hi there!
Dura matter is a thick membrane made of dense irregular connective tissue that surrounds the brain and spinal cord.. It’s also the outermost of the 3 layers of membrane called the meninges that protect the main nervous system. The nervous system has 2 main parts.

Answer:
The top left is the diploid parent cell
In the meiosis, the upper-most cell is the diploid parent cell; the below image explains the crossing over, and then independent assortment is seen in the order to make two haploid daughter cells at the end of meiosis I, and in meiosis II, four daughter cells will be formed.
What role does meiosis play in gamete formation?Meiosis is a type of cell division that occurs in organisms that reproduce sexually and plays a crucial role in the formation of gametes, which are the cells that are involved in sexual reproduction, during this process, a cell's DNA is replicated, and then the cell divides into four daughter cells, each with half the number of chromosomes as the parent cell and this process is important because it ensures that the gametes produced by an organism will have the correct number of chromosomes, which is necessary for the proper development of the offspring.
Hence, in the meiosis, the upper-most cell is the diploid parent cell; the below image explains the crossing over, and then independent assortment is seen in the order to make two haploid daughter cells at the end of meiosis I, and in meiosis II, four daughter cells will be formed.

The Galapagos island has a variety of tortoises with different physical characteristics. Can a Domed tortoise survive that lives on Isabella survive on the Island of Espanola? Explain.
Explanation:
Shell size and shape vary between populations. On islands with humid highlands, the tortoises are larger, with domed shells and short necks; on islands with dry lowlands, the tortoises are smaller, with "saddleback" shells and long necks.
Answer:
Probably not. This is because the islands at Galapagos islands are all diverse and the turtles that live on each island have characteristics that help them survive on their island and not any other island so if you were to move one of the turtles locations it probably wouldn't survive because it doesnt have the needed characteristics do survive.

what is energy?How dose energy work
Answer:
energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.

Answer:
Profundal zone is the deep water zone of any lentic water body i.e. lake or a pond where the light can no longer penetrate because it is located below the range of effective penetration of light mostly below the thermocline. The lack of light and oxygen determines the type of biological community living there

What are the 3 possible outcomes in the life of a star?
Answer:
stars spend most of their lives on the main sequence fusing hydrogen gas to helium gas. stars eventually swell up to form a red giant star. stars like the Sun end their lives as planetary nebulae and white dwarfs.
Explanation:
Answer:
The way a star dies depends on how much matter it contains—its mass. As the hydrogen runs out, a star with a similar mass to our sun will expand and become a red giant. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant.

natural elements is called
Answer:
Weathering.
Explanation:
Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.
The process when rocks break into smaller pieces due to exposure to natural elements is called weathering.
What is weathering?Weathering can occur through physical, chemical, or biological means.
Physical weathering involves the mechanical breakdown of rocks into smaller fragments without changing their chemical composition. Chemical weathering, on the other hand, involves the breakdown of rocks through chemical reactions, resulting in the formation of new minerals. Biological weathering is caused by living organisms, such as plants and animals, that can physically break down rocks or release chemicals that can alter the rocks' composition.

Group of answer choices
Predators will abandon the habitat as humans are the top predator in any ecosystem.
The ecosystem will be destabilized as abiotic resources like available space are reduced.
The costal ecosystem populations will decline until new species evolve that are adapted to live new humans.
Key species found on the barrier island will move to a new habitat.
Answer:
The ecosystem will be destabilized as abiotic resources like available space are reduced.
Key species found on the barrier island will move to a new habitat.
Explanation:
Due to living of humans on the barrier Island with adversely affected the organisms present on that Island because the loss of habitat occur due to living of humans and the important species migrated to other habitats where no humans are present. So this action greatly change the environment of barrier Island and the ecosystem will be destabilized.

1- how does modern technology provide evidence that all organisms have a common ancestor?
2- what new discoveries about evolution have modern technology made possible?
Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.

what types of cells are made by meiosis
Answer:
Meiotic cells
Explanation:
Answer:
The cells made by meiosis genetically differ from the ones made by mitosis. When a cell is created by meiosis, the cell's chromosomes are greatly reduced thus producing four Gamete cells. Gamete cells are reproductive cells and are used either as sperm or egg cells.
