Answer: Encourage students to set up a germination experiment by placing the seeds in different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to pot the same seed in more than one pot.

Explanation:

This option provides a clear and practical approach to the seed germination investigation. By setting up different conditions for the seeds, such as light vs. dark or wet vs. dry, the students can observe and compare how these conditions affect the germination process. Additionally, potting the same seed in multiple pots allows for a controlled comparison within the experiment.

By manipulating these variables, the students can gather valuable data and observations regarding the influence of light and moisture on seed germination. This approach promotes a hands-on and investigative learning experience, encouraging students to actively engage with the scientific process while documenting the changes that occur over time, such as the emergence of roots and shoots.

Explanation:

The statement that is not true regarding Ambulocetus is it lacked hind limbs. The correct option is B.

This cetacean ancestor was semiaquatic. It spent most of its time in the water but reproduced on land. Thewissen worries Ambulocetus natans resembled modern crocodiles in appearance and hunting style, consuming marine fish and maybe ambushing animals that wandered too near the water's edge.

It could have observed prey above water even while submerged thanks to the high, sideways-facing eyes on its head that resemble hippos.

2. Scientists can determine whether an extinct animal gave birth on land or underwater by the position of the head of the fetus.

3. Fossils of Basilosaurus resemble that of modern whales because there are similarities in both anatomy and size.

Therefore, the correct option is B, C, and A.

Answer:

Anacharis in High Light produces more mLof oxygen per min than Anacharis in Low Light Anacharis and in Medium  Light.

Explanation:

The increased  light intensity also increases the rate of photosynthetic activity. As photosynthesis occurs, the energy from sunlight, along with CO2 is converted to chemical energy in the form of glucose.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

or Carbon dioxide + water = energy (glucose) + oxygen

Photosynthesizing cells in green plants produce oxygen as a waste product. As this process is rate-limited, certain factors may increase the reaction rate. These include:

carbon dioxide concentration

water availability

ambient temperature

light intensity;

Answer: I think the answer would be D miohippus

Explanation:

Miohippus would be found in the uppermost layer of rock. Therefore, option (B) is correct.

Miohippus is an extinct genus of early horse that lived in North America during the Miocene epoch, around 23 to 5 million years ago. It was a small, three-toed horse that was slightly larger than its predecessor, Mesohippus.

Miohippus had a relatively short face, with a long, narrow skull and teeth that were adapted for grinding tough vegetation. It is believed that Miohippus was the ancestor of the modern horse, and that its evolution was characterized by an increase in size, a reduction in the number of toes, and changes in the shape of the skull and teeth that allowed for a more efficient grazing diet.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:

Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.

You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.

Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.

Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.

These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

MITOSIS:

Mitosis is the process whereby a single cell results in two daughter cells that are genetically identical to one another.

Mitotic division occurs in stages namely: prophase, metaphase, anaphase and telophase.

Prophase: Condensation of chromatids to more visible X-shaped structure called chromosomes.

Metaphase: Chromosomes line up at the cell's equator

Anaphase: Chromosomes are pulled apart by the spindle fibers that attached to their centromere.

Telophase: Reformation of the nuclear membrane.

According to this question, in the anaphase stage, spindle fibers start to pull away from the center of the cell to separate the chromosomes.

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.
