Explain how scientists got the space station up in space. What problem did they
encounter and how was it solved?
Answers
Answer:
scientists got the space station up in space in to small pieces.
Explanation:
The main problem which was faced by the scientist was that there was no powerful rocket which has the ability to lift the whole space station due to its more weight and carry it to the space against the powerful force of gravity. So for solving this problem, space station is taken into pieces into the space and then these pieces should be join to build the space station.

What is tonicity of cells ?
The cell of a red blood cell (RBC) shrinks when placed in a concentrated saline solution that contains more solute. Due to the diffusion process, which states that water moves from a high water concentration (RBC) to a low water concentration (saline water) when a cell is placed in a concentrated solution. As a result, a concentrated saline solution shrinks a red blood solution that has lost water.Because there are more solute particles outside the salt water than inside the cytoplasm, it is a hypertonic solution when compared to the internal liquid of the cell. As a result, the concentration gradient will cause water to osmosis out of the cells, causing them to shrivel up.The water molecules will osmosis into the RBCs from the solution if the salt solution is hypotonic in relation to them (salt solution is rarer in osmotically active particles than intracellular plasma), and this could cause the RBCs to rupture.The water molecules will osmosis out of the RBCs if the salt solution is hypertonic—the opposite of hypotonicity—leading to plasmolysis—the extensive shrinkage of the RBCs caused by a hypertonic environment.However, there may also be isotonicity—the concentration of osmotically active particles being the same in both the intracellular and extracellular fluids—between the two. There is no net movement of water molecules between the fluids due to this isotonicity. The approximate 0.3M (molar) NaCl solution yields this isotonicity.

What are some examples of suitable environments for bacteria?
How might bacteria avoid dying if an environment is not suitable?
How are bacterial cells different from plant and animal cells?
Describe how bacteria reproduce. How can bacteria acquire new characteristics?
Answers
Answer:
bacteria are found everywhere even in hot springs. Bacteria are different from other organisms because they don't have membranes bound organelles .they replicates to produce
Explanation:
Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
How might bacteria avoid dying if an environment is not suitable?Many types of bacteria, if environmental conditions become unfavourable (lack of water, increase in temperature, etc), will go into a sort of dormant state, called an Endospore.
How are bacterial cells different from plant and animal cells?Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or Golgi apparatus.
Describe how bacteria reproduce. How can bacteria acquire new characteristics?Bacteria reproduce through a process called binary fission. During binary fission, the chromosome copies itself, forming two genetically identical copies. Then, the cell enlarges and divides into two new daughter cells. The two daughter cells are identical to the parent cell.

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.

Explanation:
if the wind force is going to be pushed. by air whoch cretaes an atmosphere with water
Answer:
The correct answer is - waves.
The frictional force of the winds is the force with which the winds influence a surface. The smoother a surface is the lesser the friction, and vice versa. The water is a smooth surface, so the winds frictional force is not very big on it, but it is big enough to cause the occurrence of the waves. By constantly influencing the water with their frictional force the winds manage to move and disrupt the surface of the water, with the end result being the waves. Depending on the strength of the winds and the frictional force accordingly to that the waves can be very small, only few mm in height, or can be up to several meters in height.

PLZ thank and five star
and a brainliest would be nice:-)
Answer: D. the amount of space something takes up
============================================================
Explanation:
For example, if you have a 2 inch by 3 inch by 5 inch rectangular block, then the volume it takes up is 2*3*5 = 30 cubic inches. We can fit 30 smaller unit cubes in this 2 by 3 by 5 block.
Another example of volume would be saying that a container can hold 5 gallons, which is the amount of liquid inside the container when it's completely full.
----------
Extra info:
Choice A is false because a substance that does not have a definite shape would be a liquid. Liquids can flow and form to fit any volume. This also applies to a gas as well.Choice B is false because this refers to a solid. A block of ice has a definite shape which is in a block or cube form. Melting that ice will turn it into a liquid which then doesn't have a set shape.Choice C is false as this likely is talking about temperature. Temperature is the measure of how fast a particle is moving. The faster the particle, the more energy and higher temperature it has. On a cold day, the air particles aren't moving as fast compared to a much warmer day when they speed up more.Given the corn field snapshot and the incomplete table below, what could the missing values be?

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.
