As a body cell grows, the ratio of _______ to volume _________. Before it grows to large, a cell will divide into two ________ cells. So that each new cell receives its own genetic instructions, the cell ________ or copies, all of its DNA.
Answers
Answer: As a body cell grows, the ratio of SURFACE AREA to volume INCREASES. Before it grows to large, a cell will divide into two DAUGHTER cells. So that each new cell receives its own genetic instructions, the cell REPLICATES or copies, all of its DNA.
Explanation:
As a body cell grows, the ratio of surface area to volume decreases. Before it grows to large, a cell will divide into two daughter cells. So that each new cell receives its own genetic instructions, the cell replicates or copies, all of its DNA.
The volume of a growing cell increases at a larger pace than the surface area. Hence the ratio of the surface area to the volume of the cell keeps decreasing. At a certain point, the signal to divide is given and this leads to the division of the cell into two daughter cells.
Just before the division, the genetic material of the cell is replicated and other important biomolecules are synthesized before the final call can be made.

State the functions of the skeletal system, including the number and the major bones in the human skeleton.
Answers
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.
Look at the diagram of the digestive system, write down in order . the organs that food passes through as it moves through the digestive system
answer as a 7-6th grader please
Answers
The order of the digestive system is:
1) the mouth
2) the esophagus
3) the stomach
4) the small intestine
5) the large intestine (colon)
6) the anus
First it enters the mouth then goes down the esophagus ( a long tube made of smooth muscles) I after that, it enters the stomach where it is further broken down by acids. The useful enzymes are sent to the liver to be circulated by the blood vessels. The rest is then sent down to the intestines where the small intestine secretes enzymes ne the large intestine collects waste. The anus and rectum push waste out the body, this waste is known as feaces.

Which light produces the most glucose in the plant? (remember that glucose is a food product (sugar) made during photosynthesis in a plant.)
blue
green
yellow
red
Answers
Answer: Red light
Explanation: Plants absorbed white light best than any other light, however, red light is better light than other lights after the white light due to its long wavelength and the right amount of energy to excite or stimulate the electrons of the light center of the chlorophyll and transit to a higher energy level which increases the rate of photosynthesis.
Red light is a light with a longer wavelength which helps in radiate and heat the chlorophyll than its counterpart. A high rate of photosynthesis results in more glucose production.

Scientists sometimes work on research to create better plants. These plants have traits that are more useful to people than are the traits found in wild plants. A scientist might start by choosing a trait to change. Then, the scientist must decide on a breeding strategy to change that trait. If the scientist chooses a good trait and a good strategy, the result might be a new and more useful plant. Imagine for a moment that you are about to start working on a similar project. Explain your self in a paragraph or 2 of no less that 5 sentences.
Question — Identify one trait of a plant that could be changed by selective breeding.
Question — Explain how the change you describe would make the plant more useful.

This is an illustration of a typical food web. You might see a food web like this where you live. The organisms responsible for changing sunlight into food would be the Response area. Grass is one of these. You can see that the grasshopper and rabbit eat the grass and the bird and the shrew eat the grasshopper. Imagine that there was a big increase in the number of snakes in this area. We would then expect the Response area numbers to drop. In this food web, we consider the hawk a Response area. If the hawk population increases, we would see a drop in birds and shrews and snakes! The fungi and bacteria in the food web are examples of Response area. They break down any and all dead organisms. This helps to recycle matter.

A pedigree chart is used to _______.
predict percentage of offspring with a trait
predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents
Answers
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.

Answers
Answer: invasive species
Explanation: When you introduce a new animal into a system that it wasn't in before, you run the risk of that species becoming invasive.
That is when it starts to dominate. Once the organism starts to dominate,it starts to have all the other species in that food chain crumble. Once the food chain in that area starts to collapse it causes the whole environment to destroy itself. Soon the environment's animals are all gone causing the plant growth to explode.
