How can polyploidy cause speciation in plants?

Plants can sexually reproduce only when they are polyploid. Having the condition is normal in plants.
Plants can asexually reproduce or pollinate themselves. This allows polyploid individuals to reproduce.
Plants can repair polyploidy and obtain healthy cells. This allows plants to survive and reproduce.
Plants are not affected by polyploidy. Plants with the condition can reproduce normally.

Answers

Plants can asexually reproduce or pollinate themselves. This allows polyploid individuals to reproduce, this results develop cause speciation in plants, hence option B is correct.

What is polyploidy in plants?

Polyploidy, which occurs when two or more genomes fuse within one nucleus, causes each cell to possess more than two pairs of homologous chromosomes.

Most angiosperms exhibit polyploidy, which is crucial for the survival of the agricultural crops on which people depend.

Three or more sets of homologous chromosomes are present in polyploid plants. These plants' increased chromosome count is the outcome of a genome duplication event.

Therefore, plants can asexually reproduce or pollinate themselves. This allows polyploid individuals to reproduce.

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.

Given these choices, the correct answer is:

Food Web

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.

B. Mitochondrion because it is the powerhouse of the cell and it is where sugar is broken down into ATP

The organelle that converts sugars into energy is the mytochondrion, which is the powerhouse of the cell, so the correct option is B. mitochondrion

Which organelle converts sugars into energy?

The mitochondrion is often referred to as the "powerhouse" of the cell because it is responsible for generating energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration.

During cellular respiration, glucose (a sugar) and oxygen are metabolized within the mitochondria to produce ATP, which serves as the primary energy currency of the cell. The mitochondria are present in most eukaryotic cells and play a crucial role in energy production.
