Answers
Answer: Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help Balance the amount of water in your body.Balance your body's acid/base (pH) level .Move nutrients into your cells, Move wastes out of your cells, Make sure that your nerves, muscles, the heart, and the brain work the way they should. Sodium, calcium, potassium, chloride, phosphate, and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink. The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance. Treatment helps you to manage the imbalance. It also involves identifying and treating what caused the imbalance.
How are land plants adapted to survive on land? What are the benefits of living on land rather than in water?
Answers
Answer:
Sample Response: Plants that are able to survive on land developed specialized vascular tissue such as xylem and phloem. This vascular tissue aids in the transport of water and other resources needed by the plant. Land plants also developed a cuticle, or waxy layer, to prevent water loss and seeds to protect young plants. The benefits of living on land are greater access to sunlight and less competition with other plants for resources.

Vertebrate animals are organisms that have a spinal column and use bones to support their weight. Scientists consider bones to be an organ of the skeletal system. What organ of a plant is most similar to a bone in animals.
A. Stem
B. Root system
C. Cell wall
D. Phloem
Answers
Answer: The stem, the stem keeps the plant stable. Much like our skeletal system.
The stem cells of the organ of a plant is most similar to a bone in animals. Hence option A is correct.
What is vertebrate?Vertebrate is defined as any terrestrial animal, which is the most prevalent subphylum of the phylum Chordata. Vertebrate animals are those that have a backbone. There are many vertebrates on the planet today, and they are divided into 7 classes according to their physiological and anatomical characteristics.
Stem cells are defined as unique human cells that can differentiate into a wide range of cell types, from brain cells to muscle cells. Stem cells can differentiate in the body into a wide range of various cell types. They act as the body's system for repairs. Adult stem cells and embryonic stem cells are the two primary categories of stem cells.
Thus, the stem cells of the organ of a plant is most similar to a bone in animals. Hence option A is correct.

Sponges, members of the phylum Porifera, are sessile filter feeders that lack tissues or organs. Instead, specialized cells have unique functions like ingesting food, support, and reproduction. Such specialization within a sponge body is a result of
A) cytokinesis.
B) cell cleavage.
C) cell differentiation.
D) gamete fertilization
Answers
Answer:
C) cell differentiation.
Explanation:
Cell differentiation is a process undergone by a cell in which it changes to a specialized form. During the process of cell differentiation, some genes in a single cell becomes turned off or on in a process called GENE EXPRESSION to give rise to cells with specialized functions.
This is the case of this sponge whose specialized cells perform unique functions like ingesting food, support, and reproduction. The specialization of the cells within the sponge is as a result of the process of CELL DIFFERENTIATION.

Answer:At this point, it should be clear that eukaryotic cells have a more complex structure than do prokaryotic cells. Organelles allow for various functions to occur in the cell at the same time. Despite their fundamental similarities, there are some striking differences between animal and plant cells (see Figure 1).
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.

Answers
Various methods can be employed in the separation of heterogeneous mixtures from a solution comprising the solute and the solvent.
The correct answer is:
Option C. Particle Size.
This can be explained as:
Sand and gravel have two different sizes and can be separated on the basis of particle sizes.Sieving is a method that can be employed to separate gravel from sand.Sand particles being small will pass through the sieve while gravel being big in size will remain on the top of the sieve.Therefore, particle size will be the parameter by which sand and gravel can be separated.
