What is the function of the cellular structure labeled “A” in the diagram below.

The algae, walleye pollock, and orca populations could have all affected the moon jelly population. What additional evidence do

STALIN [3.7K]

Answer:

There is a balance of resources, shelter, and number of species inside the region which is under consideration. While, the moon jelly's population may increase due to lack of presence of the competition for the resources that are present by means of other consumers of zooplankton that would enhance the growth of the moon jelly's.
Along, with that the decrease in the number of predators which are mainly the big marine animals inside the region that would increase the level or growth of the moon jelly's.

Differentiation occurs when: the sperm and ovum meet. cells begin to specialize. the combined material from both gametes meshes

musickatia [10]

Answer:

The correct answer is option - cells begin to specialize.

Explanation:

Embryonic differentiation is a process in which the cell begins to divide and to be destined to make a specific cell line different from another cell. Each differentiated cell has fate to perform a specific function in later development in the body.

The embryonic cell differentiation takes place when the cell begins to specialize which is occurs after the cleavage of a zygote which triggers the differentiation process.

Thus, the correct answer is option - cells begin to specialize.

What form a spindle shaped structure of protein fibres on which the chromosomes move during nuclear division?

frez [133]

Function of centrioles

An organelle that forms a spindle-shaped structure of protein fibers on which the chromosomes move during nuclear division are called the centrioles. Centrioles are part of the animal cell organelles. Hence, they are a small part of the microtubules organized and set in a particular course. Microtubules include 9 sets. Centrioles contain a cylindrical structure, packed with protein which is described as tubulin. Found mostly in eukaryotic cells beside the nucleus.

The Earth's biodiversity is determined by the variety of all living organisms on Earth. In recent years, ecologists and other sc

bogdanovich [222]

Answer-:

Preserving the biodiversity of Earth is important because biodiversity increases the efficiency of ecosystems where every species, no matter how small, has an important role to play. A greater number of species of plants means a larger range of crops. Greater diversity of organisms guarantees ecological survival for all lifeforms

Explanation:

REASONS WHY PRESERVATION OF THE EARTH'S BIODIVERSITY IS IMPORTANT-

ECOSYSTEM PRODUCTIVITY - One of the key reasons we should continue to concentrate on biodiversity protection is that it helps to improve the efficiency of the ecosystem. Naturally, a properly working ecosystem would be more immune to extreme environmental factors, such as climate change.
HEALTH DETECTIONS -The vast number of medical advances waiting to be made is one of the most significant reasons why we should continue working on saving biodiversity. To develop new cancer therapies and more, scientists use observations of plants , animals, and even microbes. As a matter of fact, all human drugs must first be tested before being tested on humans in laboratory animals. This is essential for determining their toxicity, dosing, as well as effectiveness. In some of the most remote sections of the planet, many of the animals used in these discoveries are also included.
Recreation and Natural Beauty -  The value of natural beauty is another great explanation why we should continue focusing on protecting biodiversity. There are several historical sites around the country that need to be preserved to maintain their status for future generations to enjoy, such as the redwood forest. These trees regularly have a lifespan of 600 years in the case of the redwoods. Some are as old as 2,000, too. Their growth is extremely sluggish, however. Wild and natural environments provide ways to get away from urban environments. In addition, people can enjoy outdoor activities such as bird watching, canoeing, hiking, and photography of nature.
The Ecosystem 'Survival - With a few exceptions, to survive, each species on Earth relies on the services of other species. This partnership is part of the idea of what an ecosystem is. The relationship between soil, plants , and bacteria is a pertinent example. This is known as the period of nitrogen. Other examples which are important include -: Animal waste which nourishes the soil, Crops also produce straw, which is an animal food source, As natural nitrogen fixers, algae represent and Aerate the soil with rats.
Economic Benefits -: Many advantages have been provided to humans through biodiversity, and many come in the form of products. These products are extracted and sold, and everything from crops to medicines is included.

Hence, preservation of the biodiversity of Earth is important from all aspects of life.
