The images below show the same cell, before and after reaching equilibrium. Which statement best describes what happened as the volume of the cell increased
The missing part of the question and group of options is attached as an image.
Answer:
The correct answer is - D - The number of solvent particles outside the cell decreased.
Explanation:
As the solution reached equilibrium the concentration of the solute is equal inside the cell and outside the cell, so the number of particles of the solvent must increase inside and decrease outside of the cell.
The cell volume increased due to the flow of the solvent from outside to the inside of the cell this type of diffusion of solvent is known as osmosis which leads to the swollen or bigger cell.
Answer:
The number of solvent particles outside the cell decreased.
Explanation:
In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth and are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov. The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots. A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.
Number of:
Solid:____
Fewspot:_____
White Overo:______
Answer:
Hello your question is incomplete below is the missing part

As part of an experiment, you grow some plants in an environment including carbon dioxide with radioactive carbon isotope 14C as a tracer. After a few days you take the plants out and look for the tracer. You find it primarily in the roots. How did it get there? Why is it in the roots?
Answer:
Plants make their own food with the help of photosynthesis, in which the organic carbon is formed from the inorganic carbon. Organic carbon is used as a source of energy and helps in various cellular functions.
Organic carbon mostly stored in the form of starch and other carbohydrates and also helps in forming the structure of the plants. The starch is stored mainly in the roots, fruits and stems. The main source of starch is in roots in tubers of the plants. The radioactive carbon that is found in the plant roots in the experiment is the excess carbon that stored in the roots of the plants

How are Gymnosperm and Angiosperm plants different?
Answer:
Hey! :D
Explanation:
The gymnosperms, also known as Acrogymnospermae, are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. The term "gymnosperm" comes from the composite word in Greek: γυμνόσπερμος, literally meaning "naked seeds". The name is based on the unenclosed condition of their seeds. The non-encased condition of their seeds contrasts with the seeds and ovules of flowering plants, which are enclosed within an ovary. Gymnosperm seeds develop either on the surface of scales or leaves, which are often modified to form cones, or solitary as in yew, Torreya, Ginkgo.

5. Besides being part of the composition of bone, why else do mammals need calcium?
Answer:
It's important for the contracting muscle
Explanation:
Besides being part of the composition of bones, calcium is needed by mammals for the following processes:
Formation of skeletons and teeth.Muscle contraction.Regulation of normal heart rate and nerve functions. Blood clotting. What is Calcium in living organisms?Calcium in living organisms may be defined as an important nutrient that all living organisms require, including humans in order to develop various organs like teeth and bones as well as for metabolic processes.
Apart from being part of the composition of bones, calcium is also required for the proper development of teeth and skeletons. The movement of calcium ions plays an essential role in the contraction of muscles.
The influx of calcium ions into the cells of the heart significantly enhances the heart rate of an individual in the range of 1.6 to 14.10 mm.
It also plays a critical role in blood clotting.

Why do heart cells have different characteristics than skin cells?
Heart cells have different DNA than skin cells.
Heart cells express different genes than skin cells.
Heart cells reproduce by cell differentiation.
Heart cells reproduce by mitosis.
Answer:
Heart cells express different genes than skin cells. B
Heart cells have different characteristics than skin cells because heart cells express different genes than skin cells.
Humans as multicellular organisms possess different cells in our body system. These cells perform varying functions in the body. The different functions performed by different cells is attributed to the cellular differentiation. Cellular differentiation is the process whereby an undifferentiated cell becomes specialized. The cellular differentiation occurs due to the difference in gene expression in each specific cell. All cells contain the same DNA sequence, however, they are expressed differently. Therefore, heart cells have different characteristics than skin cells because heart cells express different genes than skin cells.Learn more at: https://brainly.com/question/18546772?referrer=searchResults

The epidermis is the most superficial layer of the skin. It is composed of stratified squamous epithelium. Within the epidermis, there are five distinct layers with different features and roles. Match the appropriate skin layer with its description.
a. Stratum corneum
b. Stratum granulosum
c. Stratum lucidum
d. Stratum basale
e. Stratum spinosum
1. : Deepest layer; site of rapid cell division and melanin production
2. : Live keratinocytes connected by desmosomes produce pre-keratin
3. : Cells flatten and fill with keratin, resulting in a grainy appearance
4. : Clear layer found only in thick skin; cells full of keratin
5. : Thick superficial layer of flat, keratinized, dead cells; responsible for dandruff
Answer:
a. Stratum corneum 5. : Thick superficial layer of flat, keratinized, dead cells; responsible for dandruff.
b. Stratum granulosum 3.: Cells flatten and fill with keratin, resulting in a grainy appearance.
c. Stratum lucidum 4. : Clear layer found only in thick skin; cells full of keratin.
d. Stratum basale 1. : Deepest layer; site of rapid cell division and melanin production.
e. Stratum spinosum 2.: Live keratinocytes connected by desmosomes produce pre-keratin
Explanation:
The epidermis has five layers, starting from the deepest one they are:
The stratum basale: is the layer that has the germinative cells, called keratinocytes.
The stratum spinosum: the keratinocytes are connected, and they produce the precursor of keratin and lipids.
The stratum granulosum: the name of this stratum is due to the appearance of the cells. They produce keratohyalin, and the lipids produced in the previous layer are released, creating the layer that protects the skin against dehydration.
The stratum lucidum: They are only in thick skin, like the one that is in the sole of our feet. The cells do not have a nucleus. They are filled with keratin, which is the component of thick skin.
The stratum corneum: the more superficial layer, it is made of dead cells filled with keratine. When new cells ascend to this stratum, the old ones have to be removed by exfoliation or natural peeling.
The five distinct layers of the epidermis with different features and roles are given below: a) Stratum corneum- 5, b) Stratum granulosum- 3, c) Stratum lucidum- 4, d) Stratum basale-1, e) Stratum spinosum- 2.
The epidermis (outer layer of the skin) is the part of the skin that’s visible to the unaided eye and works to protect the body. The epidermis doesn’t have any blood vessels, so it relies on the dermis (the layer of skin directly beneath the epidermis) for nutrients and waste disposal.
The epidermis protects the internal organs, the muscles, the nerves, and the blood vessels. The epidermis also creates new skin cells and produces melanin, which gives the skin its color and reduces the absorption and effect of UV radiation. It protects the body physically, and it also protects the immune system.
