1 answer:

7 0

The groups of small cells better than one large cell at moving material in and out because they have a greater surface-to-volume ratio.

Option: A

Explanation:

This happened so as these smaller cells, unlike bigger cells, can quickly and willingly enter and move through the membranes of other cell membranes and permeable coverings. For these smaller and mini cells, it is also important to penetrate and move effectively, distribute and transport products and materials such as nutrients, oxygen and waste across the body without requiring enough energy and saving less space. They are cheaper, more effective and use less room for simple reasons, and most notably deplete less resources.

Evolution is sometimes a controversial:

Evolution is the most scientific explanation about how the life forms of earth originated and turned into the form that we see today.

I don’t think there should be a controversy because there is no other explanation that proves to be more logical than the theory of evolution. Evolution is a theory that has several supporting proofs and the theory itself was formed after several years of detailed study and observation.

I don’t think alternatives to evolution should be taught at schools. Alternative theories to evolution are based on various religious beliefs which lack a scientific basis.

Schools should be a place that enables students to do productive scientific thinking and teaching alternatives to evolution wouldn’t be a good idea.

Mariulka [41]

Answer:

within the cartilage divide and secrete new matrix

Explanation:

Chondroblasts also called as perichondrial cells form chondrocytes which are the cells of cartilage. They also secrete the cartilage matrix which forms the cartilage. This matrix consists of collagen, fibers, proteoglycans, hyaluronic acid, water and glycoproteins.

They divide within the formed cartilage too to secrete new matrix. They are called chondrocytes when they become a part of cartilage matrix. Here they grow the cartilage matrix by secreting more extracellular matrix rather than dividing. Once the cartilage formation is completed it is composed 10-20% of collagen fibers, 65-80% of water and rest is made by proteoglycan-hyaluronic acid aggregates.

Natural organic compounds produced by plants that are poisonous, particularly to insects, are known as?

svlad2 [7]

Natural organic compounds produced by plants that are poisonous, particularly to insects, are known as Botanicals.

Botanical insecticides are naturally occurring chemicals (insect toxins) extracted or derived from plants or minerals. They are also called natural insecticides. Organic gardeners will choose these insecticides, in some cases, over synthetic organic materials.

Pesticides are substances that are meant to control pests. This includes herbicide, insecticide, nematicide, rodenticide, bactericide, insect repellent, fungicide, and lampricide.

Examples of plants that are sources of commercially available botanical pesticides include pyrethrum (Tanacetum cinerariifolium), neem (Azadirachta indica), sabadilla (Schoenocaulon officinale), tobacco (Nicotiana tabacum) and ryania (Ryania speciosa)
