Explanation:

Answer:

S - Savannas are typically found in tropical or subtropical regions.

S - Savannas tend to have more trees and shrubs.

S - Savanna's climate is drier than that of a grassland.

G - Grasslands are found in temperature regions.

G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.

G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.

B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.

B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.

B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

At certain times of the year, five planets can be seen from the Earth in alignment. These are Mercury, Venus, Jupiter, Mars, and Uranus. So the correct option is option D.

When does the alignment of five planets occur and be seen in the sky?

Such a planetary alignment takes place when the planets come together on one side of the sun at the same time. This alignment occurs as a result of five planets coming in one line in the sky. These planets can be seen with the unaided eye and do not require a telescope to be seen from the Earth. This is because these planets are the brightest planets.

These planets change positions and go through certain phases where they can be sighted from the Earth except for Uranus which can be seen using a telescope in the evening sky. Uranus is the seventh planet in the solar system.

Answer:

Gills and lungs differentiate in many ways most certainly when it comes to breathing. Gills are used by aquatic animals such as; sharks, fish and octopi. Lungs on the other hand are mainly used by mammals such as; humans, dogs and hamsters.

Lungs help breathe in air for oxygen and gills help breath in the oxygen contained in the water.

There's many advantages you could have with breathing through gills and lungs, you could swim under water for much longer periods of time and you could obviously walk on land and easily breath the air.

The sentence “gametes are haploid cells” means that gametes/sex cells have a single set of unpaired chromosomes

“Gametes are haploid cells.” This sentence means that gametes contain half the total number of chromosomes that are present in the other cells of the organism.

Gametes are the reproductive cells of an organism that are involved in sexual reproduction. They are specialized cells that are produced with  the process of meiosis.

In animals, the male gamete is called sperm while the female gamete is called ovum or egg. Sperm is typically a smaller and motile gamete which fertilizes the egg to form a diploid zygote (2n) by the process called fertilization.

Gametes are important for sexual reproduction and the maintenance of genetic diversity in populations. They are also the key to the process of evolution, which can lead to genetic variations that can be passed on to the future generations.

The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.

Answer: between organisms in food webs from producers to consumers.

Explanation:

The skeletal system serves several important functions in the human body. These functions include:

1. Support: The skeleton provides the structural framework for the body, giving support and shape to the organism.

2. Protection: The skeletal system protects vital organs such as the brain, spinal cord, heart, and lungs. For example, the skull protects the brain, the ribcage protects the heart and lungs, and the vertebrae protect the spinal cord.

3. Movement: Bones act as levers for muscles, enabling body movement. The skeletal system works in conjunction with the muscular system to facilitate motion.

4. Mineral storage: Bones store essential minerals, such as calcium and phosphorus, which are necessary for various body functions.

5. Blood cell production: Red and white blood cells, as well as platelets, are produced in the bone marrow, which is found in some bones.

6. Energy storage: Yellow bone marrow, found in the medullary cavity of long bones, stores energy in the form of fat.

The human skeleton consists of 206 bones in adults. Some of the major bones include:

1. Skull: Comprised of the cranium and facial bones, it protects the brain and supports the structures of the head.

2. Spine (vertebral column): Consists of 33 vertebrae, which protect the spinal cord and support the upper body.

3. Ribcage: Includes 12 pairs of ribs, the sternum, and the thoracic vertebrae, which protect the heart and lungs.

4. Humerus: The long bone in the upper arm, connecting the shoulder to the elbow.

5. Radius and Ulna: The two bones in the forearm, connecting the elbow to the wrist.

6. Femur: The long bone in the thigh, connecting the hip to the knee, and is the longest bone in the body.

7. Tibia and Fibula: The two bones in the lower leg, connecting the knee to the ankle.

8. Pelvis: A basin-shaped structure that supports the spine and organs of the lower abdomen, and connects the spine to the lower limbs.

These are just a few examples of the major bones in the human skeleton.

Answer:

Explanation:skeletal system functions are diffrent of types . In addition to defining our shape and traits as humans, it:

enables movement: Your skeleton helps you stand and move by supporting your weight. Your bodily components are movable thanks to the cooperation of joints, connective tissue, and muscles.

Bone marrow, which makes blood cells, is found in bones. The bone marrow makes RBC AND WBC

supports and shields organs: Your ribs shield your heart and lungs, your backbone shields your spine, and your skull shields your brain.

Mineral storage: Your bones are where your body stores minerals like calcium and vitamin D.

Answer:

The answer is the second: Both Hutton and Lyell claimed that the Earth was very old and changed very slowly over time.

Explanation:

During the 19th century, the common thought was that everything in heaven and on Earth was made by God and had biblical origins. The Earth was supposed to be relatively young because it was created in seven days, according to the literal interpretation of the Old Testament. Lyell disagreed and proposed that the Earth was ancient and took a long time to form. Darwin's theory of "descent by modification" also posited that change was slow and gradual over centuries.

The bones, muscles, and sensory organs are grouped to all work together around a common goal: movement.

Sensory organs capture the information, the bones form the skeleton and the muscles that work harmoniously are inserted into the bones through the tendons, allowing the movement of the joints.

They all work together to support the body, keep it in shape and allow it to perform coordinated movements, thanks to the coordination exerted by the nervous system.

Therefore, we can conclude that the bones, muscles, and sensory organs are grouped to all work together around a common goal: movement.

During sexual reproduction, several alleles from both parent cells converge.

Whoever possesses a more dominant or recessive gene at the time the daughter cell is being formed will have an impact on the genetic material.

Due to the genetic and phenotypic diversity produced by sexual reproduction, people can choose partners based on whom best exhibits these traits.

Due to the options available to sexually reproducing animals, individuals compete with one another and are typically only able to pass on their genes to offspring who exhibit the desirable qualities.  

Therefore, during sexual reproduction, genetic material affected due to alleles transfer between parents.

Explanation:

It should take about 6 weeks to see the Germination, until then continue watering it and giving it sunlight

The seed germination investigation during the students' summer vacation involves selecting various seeds (e.g., beans, peas, sunflower) and setting up an experiment. They will place the seeds in different conditions, like light vs. dark or wet vs. dry, and pot the same seed in multiple pots. Throughout the investigation, the students are expected to carefully observe and document the changes that take place over time, including the growth of roots and shoots. This hands-on approach allows them to gain practical knowledge of seed germination and develop essential scientific skills in observation, data collection, and documentation.

Answer:

Genetic engineering is a type of biotechnology that involves manipulating the DNA of an organism to create desired traits. This can be done through various techniques, such as gene editing or gene splicing. One benefit of genetic engineering is that it can be used to create crops that are more resistant to pests and diseases, which can increase food production and reduce the need for harmful pesticides. However, one risk of genetic engineering is that it can lead to unintended consequences, such as the creation of superweeds or the loss of biodiversity.

For society, genetic engineering can also have both benefits and risks. One benefit is that it can be used to create medicines and vaccines that are more effective and targeted, which can improve public health. However, one risk is that it can lead to unequal access to these treatments, as they may be expensive and only available to those who can afford them.

In terms of the environment, genetic engineering can also have both benefits and risks. One benefit is that it can be used to create crops that require less water or fertilizer, which can reduce the environmental impact of agriculture. However, one risk is that it can lead to the spread of genetically modified organisms (GMOs) into the wild, which can have unknown effects on ecosystems.

Overall, while genetic engineering has the potential to bring many benefits, it is important to carefully consider the risks and unintended consequences before implementing it on a large scale.
