Answer:

The mutation that takes place in the somatic cells are not carried from one generation to another generation. The mutation in the red blood cells cannot takes place because the red blood cells does not have nucleus in them.

Explanation:

Mutations occuring in somatic cells can not be carried from one generation to another. Mutations within red blood cells are unable to take place because the red blood cells themselves don’t contain a nucleus.

Answer:

Lungs.

Explanation:

Lungs are the organs that are responsible for gaseous exchange in humans. The lungs absorb oxygen from the air that is required for the process of respiration while on the other hand, carbon dioxide is transferred from the cells to the lungs through blood because carbondioxide gas is a waste material that is produced during respiration so it can be removed from the body with the help of lungs..

Explanation:

When your doing a physical activity like running Anaerobic respiration is used.

Answer:

Through facilitated diffusion

Explanation:

A molecule that finds it difficult to enter through the cell membrane's phospholipid bilyaer can be assisted in doing so through a process known as facilitated diffusion.

Ordinary diffusion will not permit the movement of molecules against a concentration gradient or molecules can be prevented from passing the phospholipid bilayer due to their sizes/charges. Within the phospholipid bilayer exists special passages lined with carrier or channel proteins.

These proteins facilitate some molecules that will ordinarily not pass through the bilayer to pass through their special passages. This process is referred to as facilitated diffusion.

Answer: phosphate

Explanation:

Deoxyribose nucleic acid, which is commonly referred to as DNA simply carries genetic information in an organism. The m DNA is made up of two nucleotides strands.

Nucleotides are simply the DNA's building block. It should be noted that the sides of the DNA consist alternating sugar molecules and the phosphate groups.

Answer:

parasitism is when one animal harms another like a parasite. for example mosquitos and humans have a parasitism relationship because mosquitos harm humans. in total parasitism means the relationship in which one benefits and the other is harmed. mutualism is when both benefit and no on is harmed. an example of mutualism is when oxpecker (a kind of bird) eats the bugs off of a rhino, the rhino gets pest control and the bird gets food. and competition is the relationship between organisms that need and search for the same resources in the same place. for example predators of different species search for the same prey.

i hope this helped!!

Explanation:

in total parasitism means the relationship in which one benefits and the other is harmed

mutualism is when both benefit and no on is harmed.

competition is the relationship between organisms that need and search for the same resources in the same place

There are three main stages in the cellular respiration

1.Glycolysis

Glucose is turned into two molecules of pyruvate. This process takes place inside the cytoplasm and does not require O2

2.Kreb's cycle(TCA cycle)

This proces takes place in the mitochondrial matrix.Electrons are incorporated in the molecules that will be used in the next step.

3.Electron transport chain

This process takes place in the mitochondrial membrane. Energy from the electrons resulted in the krebs cycle is used to pump protons in the inter membranous space to form an electro chemical gradient. This will lead to the oxydative phosphorilation(ATP synthesis)

Answer:

The correct answer would be- reduced human interference to the habitat.

Explanation:

The Tundra Biome is a biome with an extremely cold region with little precipitation, short growing seasons, very poor nutrients. The Tundra biome is at risk due to global warming, which harms, plants and animal species and the ecosystem of the biome.

low carbon emission by reducing planet-warming pollutants by reducing the fossil fuels  is key to safeguarding Earth's tundra habitats and liting industries are the

Answer: Tundra is the coldest biome on Earth.

Explanation:

It has become sensitive to the trend of global warming the surface air temperature has risen by 0.9 °C. Many regions have experiences the record breaking high temperature in otherwise winter months since 20 century. Tundra natural fires release carbon dioxide gas in the atmosphere. The climate of Tundra can be changed by human efforts. Some activities like reducing the use of fossil fuels which release green house gases like carbon dioxide, and others which warm up the atmosphere, banning the industrial activities nearby regions, and protection of certain species affected by the rising temperature.

Answer:

A Black surface will absorb all colors.

A green surface will absorb all colors and reflect green.

=> Any surface which absorbs all the colors appear to be black because no color is reflected.

=> A surface color is a color which is reflected by it.

For example:

If a surface is red colored, This means that it reflects red color. That's why it appears to be red.

If the size of a cell increases it will be more difficult (all other things being equal) for diffusion to transport materials out of the cell. Therefore, less of the cell's interior will be able to come in contact with the cell's surface. If less of it comes in contact, less of it can cross the cell membrane.

Answer:

Phylum Rhodophyta and phylum Ochrophyta.

Explanation:

Phylum Rhodophyta and phylum Ochrophyta are the phylum that contains the largest multicellular forms of algae.  Algae belongs to phylum Rhodophyta also called red algae are used for commercial production of food and gels while on the other hand, algae of phylum Ochrophyta also known as brown algae are used to produce alginates, which are used as food additives in different products and as a thickening material.

Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use

She has two different alleles for eye shape, one from each parent

You always receive 1 allele from each parent, and you're heterozygous, those alleles are different.

Sandra is heterozygous for eye shape, this means she has two different alleles for eye shape, one from each parent. The correct option is b.

Heterozygous means the person who has different alleles from each parent for the same type of character. There are two types of people, heterozygous, which contain different alleles for the same character. Homozygous, which means he has only one allele for one character.

Sandra has two alleles for eye shape, which means she got different eye shapes from her father and mother. She got two eye shapes, and now the allele which is dominant will be shown in her phenotype of Sandra. The other will be recessive.

Therefore, the correct option is b, She has two different alleles for eye shape, one from each parent.

Answer:

...

Explanation:

It is definitely organism A. Cellular respiration has a net of 32 molecules of ATP while glycolysis only has 2. This is because cellular respiration involves Kreb's cycle which causes the molecules to be constantly reduced and oxidized as electrons move from one molecule to another. This Is known as the electron transport chain. This releases a molecule of ATP every time a redox reaction occurs.
