Answer:

Mitochondrion

Explanation:

The enzymatic reactions of cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria. Cellular respiration occurs in the double-membrane organelle called the mitochondrion. The folds in the inner membrane are called cristae.

Answer:

The biosphere is the sphere that oxygen in our blood is part of.

Answer:

Q2->They all form acids when combined with hydrogen. They are all fairly toxic. They readily combine with metals to form salts.

Q3->Because their outermost orbit is complete.  In Mendeleev's original periodic table there was no place reserved for noble gas.  They were discovered in end of 19th century.  So Mendeleev created zero group without disturbing original periodic table.

Explanation:

Answer:

Herbivore and carnivores.

Explanation:

This forest fire greatly affected two consumer populations such as herbivores and carnivores because herbivores has no food available due to forest fire. The unavailability of food for the herbivores leads to the decrease in herbivore population that also adversely affected the population of carnivore ( those organisms that feed on herbivores) so both are affected from the forest fire.

Answer:

they act like they have the right to treat you like dodo but if he is nice he will be prob either shy or hide his feelings.

Answer:

Carrier proteins can change their shape to move a target molecule from one side of the membrane to the other. ... The carrier proteins involved in facilitated diffusion simply provide hydrophilic molecules with a way to move down an existing concentration gradient (rather than acting as pumps).

Answer:

B

Explanation:

Answer: Shield, Cinder Cone, and Composite volcano.

Explanation: A shield volcano is a volcano that is formed with lava is very runny and spreads to a wide area and then cools to form a shield volcano. These are common at Hawaii.

A cinder cone volcano is the smallest volcano. It's made from minor eruptions and cinders. They're short and usually erupt for a short period of time. Mexico's Parícutin volcano, is a cinder cone.

Composite or stratovolcanoes are the most common type of volcano. They form from thick, less runny lava. Since it is so thick, it cools then makes the volcano taller. Mount st helens, in Washington state is a stratovolcano.

The plant is growing upwards, defying gravity so it is negative gravitropism

Answer: All of them but option 2

Explanation:

Answer:

Both answers are B.

Explanation:

Answer:

- Cell membrane

- Cytoplasm

- DNA

- Ribosomes

Muscle cells need more mitochondria to produce enough energy to function

Answer:

-The sun

-shadow

Explanation:

-The sun rises in the general direction of east and sets in the general direction of west every day, so you can use the location of sunrise or sunset to get an approximate idea of direction.

-The shadow will always move - or, more precisely 'grow' in the west-to-east direction. (Before noon, when the sun is rising, the shadow will grow shorter and after noon when the sun is setting, the shadow will grow longer)

Answer:

This is a map of a Mountain landform because the rings get smaller until the top of the mountain. Also the altitude goes up until it reaches the top.

Explanation:

Answer:

The correct answer is -

a. Amino acid

b. dipeptide

c. dehydration synthesis.

Explanation:

The monomer is a molecule that reacts with one or more monomer molecules to form a chain or polymer. In the given reaction the two amino acids react together to form a dipeptide.

The dimer is a molecule that is made up of two monomers and in this reaction, two amino acids form a dimer dipeptide. The dehydration synthesis is a reaction in which a water molecule is lost.

Answer:

Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.

Artificial selection, also called selective breeding, is the process where humans identify desirable traits in animals and plants and use these traits to develop desirable phenotypic traits by breeding. Natural selection is a natural process. Artificial selection is an artificial or human-made process.

Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. ... Selective breeding can be used to produce tastier fruits and vegetables, crops with greater resistance to pests, and larger animals that can be used for meat.

Explanation:

Hope it is helpful.....

Answer:

Selective breeding and artificial breeding are essentially the same thing because both terms mean to cause changes in animals and plants. Selective breeding and artificial breeding both occur when humans intervene with the natural selection process.

Answer: Carbon dioxide becomes a poisonous gas when there is too much of it in the air you breathe. Besides the effects it can have on the planet and the atmosphere, carbon dioxide poisoning can lead to central nervous system damage and respiratory deterioration in humans and other breathing creatures.
