Novosadov [1.4K]

Answer:

Each biome has a unique set of environmental conditions and plants and animals that have adapted to those conditions. The major land biomes have names like tropical rainforest, grasslands, desert, temperate deciduous forest, taiga (also called coniferous or boreal forest), and tundra.

Explanation:

A biome is different from an ecosystem. An ecosystem is the interaction of living and nonliving things in an environment. A biome is a specific geographic area notable for the species living there. A biome can be made up of many ecosystems. For example, an aquatic biome can contain ecosystems such as coral reefs and kelp forests.

Why was helium and hydrogen the first elements to show up in the universe?
laiz [17]

Hey there! I could help you out with your question.

°.✩┈┈┈┈∘*┈┈୨♡୧┈┈*∘┈┈┈┈✩.°

According to research it claims that "Within about 3 minutes after the Big Bang, conditions cooled enough for these protons and neutrons to form hydrogen nuclei. ... This is when recombination occurred — neutral hydrogen (and helium) finally appeared because they could “recombine with” (hold on to) electrons without easily losing them to stray radiation."The Big Bang created the elements on the periodic table, building blocks that help make up the universe. ... In stars, hydrogen atoms fuse to create helium — the second most common element in the universe, according to Encyclopedia.com. Helium has two protons, two neutrons and two electrons. Hydrogen is known to be the first element in the periodic table of elements. It has one proton in its nucleus and one outter electron. It is a very light gas and also flammable. ... Its atomic symbol is H and its atomic number is one.

What occurred during immune system development to result in the presence of antibodies that can bind to the thyroid receptor? g
almond37 [142]

Answer:

If the immune system has a destructive and autoimmune response, it produces specific antibodies, which bind to the receptors of the thyroid cells and destroy them thinking that they are antigens or factors not characteristic of the body.

Explanation:

This happens because the thyroid cells do not present on its surface the histocompatibility complex, which is a surface protein similar to the proper and non-proper "seal", that is, it is the demarcation by which the antibodies and the cells are guided to recognize what foreign to the organism.

The histocompatibility complex is sometimes absent or rather mutated, thus generating that these cells are considered not their own and that the antibody is a receptor in order to generate the autolysis pathway or even the immune defense pathway.

USPshnik [31]

When we want to get a bacterium to make a chemical normally made by a human, we take the gene from the human and put it into the bacterium by using a bacterial enzyme known as <u>DNA ligase</u>

<h3>What is are bacteria?</h3>

Bacterial are microscopic unicellular organisms which are made of prokaryotic cells. They reproduce asexually.

Some bacteria which are saprophytes; organisms which feed on dead and decaying organisms while some bacteria are parasites.

So therefore, when we want to get a bacterium to make a chemical normally made by a human, we take the gene from the human and put it into the bacterium by using a bacterial enzyme known as <u>DNA</u> <u>ligase</u>
