3.What are the functions of vacuoles, lysosomes, and the
cytoskeleton?

Answers

Answer 1

Answer:

In plant cells, vacuoles maintain water balance. Lysosomes break down excess or worn-out cell parts. The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.

Explanation:

Answer 2

Storage, waste disposal and structural support  are the functions of vacuoles, lysosomes, and the cytoskeleton.

The following are the roles of vacuoles, lysosomes, and the cytoskeleton: Vacuoles are membrane-bound organelles that can be found in the cells of fungus, protists, and plants. They serve a variety of purposes, such as: Vacuoles have the capacity to store a wide range of materials, including waste materials, pigments, water, and nutrients. They control the osmotic equilibrium and aid in maintaining turgor in plant cells. Vacuoles in plant cells can be used as a storage space for a variety of waste materials and poisons that are damaging to the cell. They keep these molecules apart and stop them from harming other cell components. Support for structure: In plant cells, the huge central vacuoles press on the cell wall to support structure and preserve the form of the cell. Lysosomes are membrane-bound organelles that can be found in cells.

how will an increase in number of malaria infection would affect the south african economy​

Answers

Malaria is one of the world's most serious tropical diseases and imposes very significant economic costs on some of the poorest nations on earth. This study estimates the direct and indirect costs of malaria to South Africa and examines the issues surrounding the use of DDT as an anti-malaria insecticide.

Early records of malaria cases by Europeans in the late 19th and early 20th centuries show that malaria was a severe inhibitor of economic development and caused large economic costs. The current malarial areas in South Africa today are about one fifth of the size they were at the beginning of the 20th century. The historical success in controlling malaria is due in very large part to the use of DDT in malaria vector control.

In recent years, however, there has been a sharp rise in the number of malaria cases in South Africa, and indeed throughout Southern Africa. This rise is due to a number of factors, such as high rainfall in recent years, increased migration and a reduction in the use of DDT in vector control. The rise in malaria cases imposes heavy costs on the local and national economies. The economic cost (direct costs include the costs of care and control of malaria, and indirect costs include the losses in productivity and lost future earnings from death) of malaria in South Africa is conservatively estimated to be around R124 million (US$20 million) in 1997/98. Malaria in selected Southern African countries could cost as much as US$1,000 million, or 4% of GDP in 1998. In South Africa, malaria usually occurs in rural areas with agricultural and labour intensive industries. The incidence of malaria in these areas has severe economic impacts and as in the past, continues to hamper economic development

For a number of reasons, DDT is being phased out of the malaria control programmes in South Africa. Numerous environmentalist organisations have lobbied strongly for the banning of DDT, despite the success of the insecticide in saving lives and preventing disease in developing countries. While DDT is not an ideal insecticide, it does have numerous advantages over the alternative insecticides and has a proven track record. Although DDT is currently used by a number of Southern African countries in malaria control programmes, the UNEP Governing Council is pressing for the banning of DDT and eleven other persistent organic pollutants (POPs).

The potential banning of DDT highlights a trend whereby environmental pressure from mostly developed countries imposes standards on developing countries where they are neither accepted nor appropriate. While there are alternatives to DDT, these are all more expensive and frequently more complicated to use than DDT. The banning of DDT would not only remove an important anti-malaria weapon, but will result in countless deaths and very significant economic costs (perhaps as much as US$480 million) on countries that can ill afford it. Hope this helps! Mark brainly!

What's a representation of all the producer and consumer relationships within a community or ecosystem?
A. food pyramid
B. food chain
C. food web
D. food log

Answers

I think it’s either a food chain or food web. A food web is a diagram of feeding relationships that include multiple intersecting food chains.

Hello!

Let's look at some definitions!

A food pyramid is levels of predators, in an pyramid shape to show the successive.

That does not match the definition your question provided, so we can move on.

A food chain is a series of animals who depend on each other for food/buisness.

Again, it does not match, this is a series, not an entire ecosystem.

A food web is a connection of food chains, which show the entire relationships of an ecosystem.

This definition is fairly close to the listed definition, lets keep this in mind.

A food log is a chart of what you eat each day.

Trick answer! This has nothing to do with the subject.

Answer:

You have a trait (plant color) and you have two possible outcomes for it (purple and white). You know that some alleles for white were present in one of the parent plants, so you know they must be present in the offspring too. But they're expression is covered up by the purple alleles from the other plant, so you know that purple is dominant to white.
