Part A: Organize Your Information
After you’ve gathered your research and answered all your questions, create an outline in the answer space. Use the outline to organize your presentation in whatever way you think is best. Following these guidelines for writing a five-paragraph essay may help you structure your outline. Make sure your outline includes a works cited screen at the end to document the authors and websites you consulted.

Part B: Select Audio and Video
An audio-visual presentation uses both pictures and words to present information. Follow these tips as you build your presentation:

Limit text: Insert key words or phrases highlighting your points instead of typing your entire speech on the slide.
When possible, use pictures instead of words: Use representative figures such as pictures, graphs, and charts to convey information or evidence rather than huge blocks of text.
Fill in the speaker’s notes: Presentation software includes a notes section where you can add speaker’s notes for your own reference. In this section, you can cover all the details you want to talk without showing them on your slides. Your speaker’s notes should be clear and coherent enough so that someone else could deliver the presentation to an audience. You must complete your speaker’s notes to get full credit for the assignment.
Identify two to three audio, video, or photo resources that you wish to use in your presentation. Use the Insert Image button to add any images you selected.

Make sure you complete the presentation within the time allotted. Speak audibly and clearly. Maintain eye contact with your audience or the camera throughout the presentation.

Submit your presentation to your teacher along with this activity.

Answers

Answer 1

1. The protection of forest is important to preserve resources.

2. The advantage of reforestation is that it preserves species native to the area and the disadvantage is that it can lead to a reduction in biodiversity.

3. New trees don't provide the same resources for animals in the forest as adult trees do.

What is reforestation?

Reforestation can lead to a decrease in biodiversity, increased soil erosion, and a loss of water resources if it is done improperly

They protect us from erosion, clean the water we drink, and serve as a critical barrier against climate change. A large portion of the world's diverse array of plants and animals can be found in forests, which also provide essential natural resources like food, medicine, and timber.

Newly planted trees are unable to support habitats for wildlife, endangered species, or biodiversity. An existing forest, however, is already full of sturdy, old trees that can absorb much more carbon; all they require is protection from logging.

The arrangement of each pair of homologous chromosomes on the metaphase plate during metaphase I is random with respect to the arrangements of other pairs

Answers

During metaphase I, the arrangement of the each homologous chromosome pair just on metaphase plate is random in comparison to the layouts of other pairs.

Meiosis is a form of cell division that occurs in sexually reproducing organisms and results in a reduction in the number of chromosomes inside gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, with two sets of chromosomes (one from each parent). To sustain this condition, the sperm and egg that combine during fertilisation must be haploid, meaning they have a single chromosome set. During meiosis, every diploid cell divides twice to produce four haploid daughters cells — the gametes.

Alleles segregate, meaning separate, during meiosis, such that each gamete has an equal chance of receiving either of the two alleles existing in the diploid person. Mendel referred to this phenomenon as the law of segregation, which might also be seen in a monohybrid cross.

in the cell on the left, how many chromosomes are present during prophase?

Answers

6 chromosomes are present during prophase in the cell on the left.

During prophase, each cell contains twice as many chromosomes as a parent cell would normally have. Before going through mitosis, a parent cell first copies its DNA.

Human cells, for instance, typically contain 46 chromosomes. There are 92 chromosomes total during replication.

Prophase is the initial stage of mitosis, which divides the duplicated genetic material present in a parent cell's nucleus into two identical daughter cells. The chromatin, or DNA and protein complex, that makes up the nucleus condenses throughout prophase.

The 92 sister chromatids, which are housed within the cell's nuclear envelope, start to disintegrate during prophase.

Answers

If the uterus is cut in a vertical fashion (superior to inferior), the resulting outcome for the patient would be a complete uterine incision or hysterotomy.

This type of incision is typically used in cesarean delivery (C-section) procedures, and it allows the surgeon to access the uterus and deliver the baby through an incision in the abdomen and uterus. Because the uterus has circular fibers that aid with contractions and the bottom portion becoming horizontal, the incision is typically made through the lower segment of the uterus, which is thinner and less muscular than the upper segment. This allows for a less traumatic incision and reduces the risk of bleeding and injury to the mother and baby. This incision also allows to minimize the risk of damage to the muscles of the uterus, which can affect future pregnancies.

What gas is required in order for photosynthesis to occur?

Answers

Carbon dioxide gas is required in order for photosynthesis to occur.

During photosynthesis, shops take in carbon dioxide( CO2) and water( H2O) from the air and soil. Within the factory cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

6 motes of carbon dioxide are needed, one for each carbon snippet in glucose. 6 motes of oxygen are produced as a by-product of water oxidation. Sun provides the free energy demanded to make the endergonic pathway do.

What is venous blood flow?

The blood pressure in the vessels lowers when blood flows from arteries to veins.

Many larger veins have valves that provide one-way blood flow toward the heart to aid in venous blood flow.

Contracting skeletal muscles massage veins, which forces blood toward the heart. The valves close as a result of the blood flowing backward as the muscles relax. Venous blood flow can also be aided by respiratory motions.

The ratio of the pressures in the thoracic cavity and abdominal cavity during inspiration.

Due to the pressure differential, blood moves from the abdominal cavity to the thoracic cavity during inhalation.

Due to the shortage of oxygen during this process, the blood pressure in the vessels falls. Many of the bigger veins include valves that provide one-way blood flow toward the heart to help with venous blood flow.

By doing this, blood backflow is reduced. In addition, as the skeletal muscles contract, blood is forced toward the heart by a massage of the veins. The valves close when the muscles relax, preventing backflow. Venous blood flow can also be aided by respiratory motions.

Many bigger veins include valves that enable blood to flow in one direction only, towards the heart, to aid in venous blood flow.The blood is pushed toward the heart when skeletal muscles contract by massaging the veins. Blood flows backward as the muscles relax, closing the valves as a result.Venous blood flow can benefit from respiratory motions as well.

They are also known as transmembrane proteins because they span the entire width of the membrane, with one or more segments of the protein extending into the hydrophobic interior of the lipid bilayer and one or more segments extending into the hydrophilic exterior.

Integral membrane proteins play a variety of roles in the cell, including transport of molecules across the membrane, cell-to-cell signaling, and structural support. They can be divided into several categories based on their function and structure, including channel proteins, receptor proteins, and structural proteins.

Channel proteins are a type of integral membrane protein that form a pore through the membrane, allowing ions or small molecules to pass through. These proteins are selective, meaning they can only allow certain types of molecules to pass through.

Domestic horses have a greater diversity of coat colors than that of wild horses. The process that led to a greater diversity of coat colors in domestic horses is (1) selective breeding (3) gene alteration (2) random mutation (4) natural selection

Answers

Choosing parents with specific traits to breed with one another in order to generate kids with more desired traits is known as selective breeding.

For thousands of years, humans have carefully bred a variety of animals and plants, including crop species that produce more.

There are two types of horses in this situation: domestic horses, which are raised and produced by people, and wild horses, which are found in the wild. Selective breeding, also known as artificial selection, is a method used by humans to create new offspring with suitable and desirable traits, and it can be used to explain why domestic horses have different coat colors. These breeders choose to mate two parents who have advantageous phenotypic features, resulting in offspring with the desired attributes like strength and coat color as described.
