B. total time and total distance
Why is the line graph a curve instead of a straight line?
Answer:If it's important to display the exact values, then the straight lines do a much better job. But often you'll find that what matters is the trend and the precise measurements are secondary. ... A straight line suggests that the value between the two measurements increased linearly, while a curved line suggests otherwise.

13. Which statement correctly compares a function of lipids to a function of proteins in the body?
A. Fats insulate the body, and proteins control contraction.
B. Fats cushion the organs, and proteins insulate the body.
C. Fats coordinate body activities, and proteins provide sugars.
D. Fats store energy, and proteins provide the primary fuel for cell respiration.
The correct answer is A.
Fats thermally insulate the body, while proteins like actin and myosin form myofibrils which are the anatomical support for contraction.
Lipids and proteins are the macromolecules present inside living cells. Lipids are made of fats that insulate and proteins are involved in contraction. Thus, option A is correct.
What are the functions of lipids and proteins?Lipids have been the polymers that make the larger molecules and have been constituted of glycerol and fatty acids (triglycerides). These are stored in the fatty tissues called adipose tissues and provide insulation to the body.
On the other hand, proteins are macromolecules constituted of amino acid sequences (polypeptide). These are involved in the muscle contraction that allows the movement and motion of the muscular and skeletal systems.
Therefore, option A. the fats and proteins are involved in insulation and contraction.

Introduction:
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.
Materials:
• Microscope
• Prepared slide of muscle tissue
• Prepared slide of some internal organ such as the kidney, liver, or heart
• Prepared slide of erythrocytes, or leukocytes (from blood)
Instructions:
1. Place one of the prepared slides of animal tissue on the stage of the microscope.
2. Focus the microscope on low power. Then change to the high-power objective. Focus on the tissue, and note the cells.
3. On a separate sheet of paper, draw an individual cell that you see in the tissue. Note the shape of the cell and its other distinctive characteristics.
-What do you think the function of this cell might be?
4. Repeat Steps 1 and 2 using the other prepared slides.
5. On a separate sheet of paper, draw individual cells from the other prepared slides examined.
Questions:
What do you think the functions of the other cells drawn might be?
- (i think this differs on person to person so may need to do it yourself)
If all of the different kinds of cells which you observed had been taken from the same organism or individual, would they have all had the same genetic information?
- Yes, the cells will have the same genetic information. However, the particular combination of genes that are turned on (expressed) or turned off (repressed) dictates cellular morphology (shape) and function. Essentially meaning that though the cells share the same genetic information they do not necessarily share the same functions.
Consider specialization: What biological concept or occurrence is demonstrated by the different kinds of cells which were observed?
- Though these cells have the same DNA, they all have different phenotypes. The phenotypes are different because the cells appear different under the microscope. The cells do this by expressing different genes at different rates. For example, the blood cell is expressing the gene to make hemoglobulin while the other cells are probably expressing different genes that allow them to be specialized. Cells differentiate which means that they are becoming more specialized. Epigenetics focuses on how cells become more specialized.
Why is it important?
- This is important because it allows different parts of the body to carry out their crucial functions necessary for the whole body to run properly.

Explanation:
During winter's freezing temperatures, some plants can remove water from their cells to reduce the amount of water that will freeze inside them. Why would plants need to do this
Answer:
The expansion of excess water as it turns to ice inside the cells would break the cells apart
Explanation:
We know that water expands anomalously. It expands between 4- 0°C.
Hence water expands upon freezing. Ice has more volume than liquid water and takes up more space in plant cells.
The expansion of excess water as it turns to ice inside the cells would break the cells apart

Answer:
Gametes from both dogs are needed to maintain the correct number of chromosome in the offspring
Explanation:
Reproduction in dogs is a sexual process. During the process, haploid gametes from both the male and the female (sperm from males and eggs from females) fuse together in a process known as fertilization in order to produce diploid offspring.
The haploid gametes ensure that the offspring produced during fertilization has the correct (diploid) number of offspring. Because the production of gametes involves meiosis and crossing over of genetic materials between chromosomes, offspring produced by sexual reproduction are usually genetically different from one another. The random fusion of gametes further ensures that offspring from the same parents are different from one another.

explain why plants do not burst when immersed in distilled water
Answer:
it becames turgid
Explanation:
Plant cells have plasma membrane and rigid cellulose cell wall. When the cell is placed or immersed in distilled water, the water is absorbed by osmosis. As the cell becomes turgid, the cell wall creates an inward force i.e wall pressure that prevents the cell from bursting.
Answer
According to EasyEliMu,
Plant cells have cells membrane and cell wall. When the cell is placed or immersed in distilled water, the water is absorbed by osmosis. ( This is the reason why plants do not burst!!! ) As cell becomes turgid, the cell created an inward force, wall pressure that prevents the cell from bursting. Isotonic solution- a solution which has the same concentration as the cell sap.

HELP ASAP
Answer:
Metabolism is the chemical reactions that take place inside a living organism. The reaction occurs in the cells. Digestion can be the best association to metabolism. The metabolic system recognizes which substances can be nutritious or poisonous. In order to complete this process, water is needed. The chemicals are dissolved in water and transported. Without water, no reaction can take place.
Metabolism is considered as the set of life-sustaining chemical reactions within the living organism’s body cells.

Question 5 (1 point) Which letter represents the trough of the wave? B
A
C
E
D
WILL GIVE BRAINLY
Answer:
D
because trough is the lowest or the minimum point and here D represents it.
:))
The point (D) represents the trough of the wave.
What do you mean by wave?In physics, mathematics, and related fields, a wave is a propagating dynamic disturbance of one or more quantities. Waves can be periodic, in which case those quantities oscillate repeatedly about an equilibrium value at some frequency.
Moreover, a wave is a disturbance that moves energy from one place to another. Only energy — not matter — is transferred as a wave moves. The substance that a wave moves through is called the medium.
Hence, the highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength.

What statement best describes symbiotic relationships?
O Different species live in close associations in an ecosystem.
Abiotic factors interact in an ecosystem.
O Saprophytes respond to abiotic changes in an ecosystem.
O Ecosystem feeding levels show changes in energy.
The statement that best describes symbiotic relationships is different species live in close associations in an ecosystem. The correct option is A.
What is the symbiotic relationship?Symbiotic relationships are those relationships in which two organisms live together and depend on each other for nutrition and space. In symbiosis, both organisms help each other.
For example, cattle and egret. The egret is a wading bird that feeds on the ticks or lice of the cattle. Eating them through the body helps clean the body of the cattle, and it also provides nutrition to the egret.
In an ecosystem, different organism lives together. Tress provides space and food for the animals. Animals help in the dispersion of seeds of various plants. In short, it is symbiosis.
Thus, the correct option is A. Different species live in close associations in an ecosystem.
