B. Proteins
Hence why body builds drink protein shakes in order to build muscle.

I'm pretty sure it's mutation accumulation.

The correct answer is:

tetrad

Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci. One homologous chromosome is inherited from the organism's mother; the other is inherited from the organism's father.

Explanation:

Homologous chromosomes are produced up of chromosome pairs that are almost the same length, centromere position, and staining pattern, for genes with the same like loci. Each pair of chromosomes called a tetrad or bivalent consists of four chromatids. At this time, the homologous chromosomes change transmitted material by the process of crossing over.

The answer is D. both a and c :)

I believe the answer is B. Zygote :)

Due to bonding interactions the nitrogenous bases on one strand of the DNA will always bind with another base on the other strand of DNA. This is due to many different enzymes that help DNA to take its structure

Succession allows ecosystems to d. All of the above.
Succession allows ecosystem to recover from disruptive events, reach a stable and sustainable point and establish complex communities. Succession by the way refer to the changes that happened in the ecosystem and develop over time.

Epidermis is made up of dermis.

the answer is false cuase the  blood circulation go in diffren ways

The substance in which an enzyme acts is called the substrate 

Answer: Chlorophyll in the chloroplast

Explanation:

The chlorophyll in the chloroplast is responsible for carrying out the process of photosynthesis.

This pigment helps in the trapping sunlight and make glucose with the help of carbon dioxide and water.

Oxygen is also released as a by-product which is released into the atmosphere to be used by the living animals and plants itself.

Hence, the correct answer is chlorophyll.

The human brain is the most complex organ in the human body

Answer: a. move.

Explanation:

Cholera is a kind of bacteria that uses bacterial flagellar motor composed by stator and rotor and flagellum (plural, flagella) to move. It is located in the plasma membrane and the movement generated is the rotation of flagellum attached to the rotor, driven by the flow of protons from outside to inside the cell. Flagella are long polymers because they are constituted essentially of thousand of identical protein sub units.

Eight / ocho   8          
thats the answer for 8          

Vertebrae are the scientific term for the backbones. 
All backbones are backbones... right? :'D 

However, the vertebrae are only a bone GROUP; there are other types of bones like joints, shafts and etc which don't come under the vertebrae clssification. 

Well, to know the answer to this question, you must know the meaning of vertebrae. Vertebrae are just a connections of bones that make up your backbone. These include about 24 ligaments that make up your spine. So all vertebrae are bones since they are ligaments and other bones that make up, well, your backbone! However, not all bones are vertebrae, because your finger bones, ribs, skull, and other bones in your body aren't part of your backbone.

Hope this helps!

What controls the inheritance and traits of an individual?
Parents pass on traits or distinguishing characteristics such as eye and hair colour to their children through their genes. Many health conditions and diseases are also genetic. Genes may also influence some behavioural characteristics, such as intelligence and natural talents.

Gene controls the traits of inheritance...

This is a statement not a ?

Answer:

Photosynthesis occurs in oceans due to presence of phytoplanktons in the surface water.

Explanation:

Phytoplanktons are the phototrophic organisms that are found in surface water of the oceans. These are very tiny organisms and are present in large number in ocean surface water.

The phytoplankton release oxygen during the process of photosynthesis. Presence of a large number of these organisms in oceans leads to the production of as much as half of the oxygen present in the atmosphere.

No, I expect forest dwelling plants to exhibit a more pronounced phototropism.

Anaerobic respiration

Eventing is an equestrian event where a single horse and rider combination compete against other combinations across the three disciplines of dressage, cross-country, and show jumping.&Combined Training, and the name persists in many smaller organizations

(A) Cell cytoplasm is the first stage of cellular respiration, glycolysis occur. It is wherein almost all of the cell activities occur like metabolic pathways that includes glycolysis and also cell division. It is comprised with cytosol and the organelles of a cell.

Answer: Environmental chemist.

Explanation:

People who study the effect of human activities on the earth, land, water and other abiotic and biotic components of the earth comes under the category of environmental chemist.

There are many effects on the population of plants and animals by the various activities that is carried out by human beings.

The consequences can be positive and negative as well, so all the activities are studied by the environmental chemist.

The cell will grow faster 

That it can send signals to diffrent people
