The cell membrane:

The cell membrane is a cellular structure that separates the cell from its surrounding environment.

The cell membrane is mainly composed of lipids, i.e., phospholipids and cholesterol (steroids).

However, the cell membrane also contains membrane proteins (both integral as peripherical proteins) and carbohydrates (i.e., glycoproteins).

In conclusion, the cell membrane is mainly composed of lipids, although this structure also contains proteins and carbohydrates (glycoproteins).

Answers

Answer:

The allele for dark blue fish must be dominant and the dark blue parent fish must be homo-zygous dominant;

This would mean the dominant allele would necessarily be inherited by all offspring and since it is dominant, it would be expressed over the other allele (light blue fish)

container in direct sunlight. The scientist observes small bubbles on the surfaces of the plant's leaves on days 1 and 2, but no
bubbles on day 3. The scientist concludes that the bubbles were caused by photosynthesis. Which substance should be
added to the water in order for the bubbles to reappear? (1 point)

Answers

Answer: Are there any options? you either add C02 because it has run out gas or you and in minerals that also contain C02.

Explanation: you need C02 to have photosynthesis, so with a closed off lid,  the gas is going to eventually run out.

Carbon dioxide should be added to the water in the container in order for the bubbles to reappear in the glass container while placed in sunlight. Carbon dioxide is a component of photosynthesis.

What is Photosynthesis?

Photosynthesis is the process by which plants prepare their own food in sunlight and in the presence of carbon dioxide gas. Photosynthesis process takes place in the chloroplast of cells.

Photosynthesis is an anabolic reaction in which carbon dioxide and water reacts in the presence of sunlight which is trapped by the chlorophyll present in the leaves of plant to produce glucose (carbohydrate) and oxygen gas, which is later utilized in the process of respiration.

b. Which types of reproduction are followed in sugar cane plant and in mango tree?

Answers

Sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.

Sugar cane is usually reproduce by using asexual reproduction i.e. by the use of pieces of stem of sugar cane called setts that contain at least one node. It is necessary that these cuttings contain a node because when they are placed and covered in the ground, primary roots arise from these nodes.

While on the other hand, the mango trees can be propagated both by sexual and asexual reproduction. Sexual reproduction involves the fusion of male and female sex cells during flowering stage. Grafting, Cutting, Layering and Budding are the asexual means for the propagation of mango tree.

Among these the grafting technique is considered as the most suitable method of vegetative propagation of mango so we can conclude that sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.

What effect does increase salinity have on the density of water?

1. No affect unless temperature also changes

2. Decreases density

3. Increases density

Answers

Answer:

3

Explanation:

For example,The density of seawater depends on the content of salt. It is known that the density of salt is 2.165g/cm3, so the more salt, the greater the density of mixed liquid.

Answer:If you know that dissolution of salt only marginally affects the volume of the solution, how would you expect the density to evolve? It should reasonably increase.

Explanation:

at a given temperature, Should salts be dissolved in the water, and the volume remains reasonably constant, the density

. A solute binds water molecules around itself in a coordination sphere, and should a salt be dissolved, both anion and cation must be solvated; hence an increase in solution density with respect to water.

Read the passage.It might not be well known, but there is a desert in North America. It spans along the western side of the continent, from southern Oregon to northern Mexico. It is mostly contained in the arid area between the Rocky Mountains to the east and the fertile coast of the Pacific Ocean to the west. Researchers estimate that the desert is between 500,000 and 730,000 square miles.Differences of latitude, elevation, climate, topography, vegetation, soil, and human use have divided the desert into a cold region and a hot region. The cold region of the desert is known as the Great Basin Desert. This area covers almost all of Nevada, western Utah, and sections of the neighboring states. South of this basin is the Mojave Desert, which is the hot region of the North American Desert. This area covers much of California, southern Nevada, and some of Mexico.As a desert, the area is arid because of high evaporation, extreme temperatures, high winds, localized storms, and sun-beaten land. Life in the desert is a struggle for humans. People do live in this desert, but the pockets of people are dispersed and isolated. Native Americans and European settlers have added to the population of the region. Despite the harsh conditions, a surprising number of plants, animals, and reptiles make the desert their home. In fact, some species can only be found in the desert.Which information best supports the idea that the desert is a difficult place to live?A. There are differences of latitude, soil, and climate among the deserts.B. The desert has pockets of people that are dispersed and isolated.C.
