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.

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.

Answer:

Earth, both on land and in water. Wherever they

live, plants provide food and oxygen to the

creatures that live nearby – including humans!

In this activity we will examine both a

terrestrial (land) plant and an aquatic (water)

plant. They have many things in common, but the

ways they get air, food and water change along

with the environments in which they live.

Explanation:

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.

(Chromosomes: A thread-like structure of DNA (nucleic acids and proteins) that carries genes.

The correct answer would be Asthenosphere.

The Asthenosphere is defined as the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.

Answer:

The answer is number 2. Fault.

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.

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.

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.

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.

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.

Answer:

absorption and circulation

Explanation:

While digestive enzymes are produced in numerous parts of the digestive system, the pancreas produces the majority of them.

In the digestive tract, digestion and absorption take place. All body cells may access the nutrients after they are absorbed, and the cells use them for metabolism.

The six actions, or functions, of the digestive system prepare nutrients for use by body cells.

The gastrointestinal tract, which was previously mentioned in this study, is a specialized sensory system.

In charge of detecting ingested glucose and relaying information to peripheral tissues or the brain to control glucose metabolism.

Therefore, In a human, the movement of glucose from the digestive tract to muscle cells is most directly a result of absorption and circulation.

energy pyramid

Explanation:

An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain.

The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ... At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.

-Membrane proteins may be enzymes to catalyze metabolic reactions within the cell.

-Channel proteins allow a specific molecule to cross the cell membrane that is unable to cross the phospholipid bilayer unassisted.

-Receptor proteins bind to ligands, initiated cell signaling pathways.

Explanation:

I did the assignment on USATestprep and got them right.

The statements accurately reflect the structure and function of the phospholipid bilayer are:

1. Membrane proteins may be enzymes to catalyze metabolic reactions within the cell.

3. Channel proteins allow a specific molecule to cross the cell membrane that is unable to cross the phospholipid bilayer unassisted.

4. Receptor proteins bind to ligands, initiating cell signaling pathways.

Phospholipids are distinct compounds with many uses. They are common and serve as the primary building blocks of cellular membranes.

Phospholipids, which are arranged as lipid bilayers, are crucial for the composition and operation of biological membranes. These layers contain proteins and carbohydrates that help in the transport of material from and to the cell.

Therefore, the correct options are 1, 3, and 4.
