Explanation:

Answer:

Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.

we need it because without heat we would not have any warm feelings.

Explanation:

Excessively heat can damage the plasma membrane and disrupt subcellular structures such as membrane proteins and enzymes.

The following are the primary subcellular structures found in animal cells: The nucleus is where genetic material is stored.

Cell membranes regulate what enters and exits the cell. Mitochondria: aerobic respiration site. Ribosomes are the sites where proteins are synthesized.

Protein denaturation occurs at high temperatures and affects protein folding, bonding, and other types of behavior.

Furthermore, membrane proteins play an important role in cell function regulation. If these are disrupted, the system will be unable to maintain homeostasis, or a stable internal environment.

Heat can damage the plasma membrane and disrupt subcellular structures like membrane proteins and enzymes.

Thus, this way, retaining too much heat can be a disadvantage to an organism.

Answer:

110 kg

Explanation:

Given

Acceleration (a) = 3m/s²

Force (F) = 330N

Required

Determine the mass of the motorcycle

This question is an illustration of Newton's second law and will be solved using:

Force = Mass * Acceleration

F = m * a

This above implies that force applied on the motorcycle is a product of its mass and its acceleration

Substitute values for F, and a

330N = Mass * 3m/s²

Make Mass the subject

Mass = 330N/3m/s²

Mass = 110kg

Hence, the calculated mass of the motorcycle is 110kg

Answer:

Answer:

The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Explanation:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

If a person possesses the genotype Bb, either the B or the b alleles can be passed on to their progeny. So, the correct option is C.

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries inside a specific gene or genetic region are also referred to as the genotype.

The term "genotype" relates to an organism's whole gene pool, or, in other words, the genetic make-up of that creature. The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning. Symbols can be used to symbolise it. For illustration, BB, Bb, and bb could be used to denote a certain gene variant.

If a person has the genotype Bb, as in the example above, then either the B or the b alleles can indeed be passed on to their progeny.

Therefore, the correct option is C.

Answer:

Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

Explanation:

Answer:

first is the right answer

Answer:

Los genotipos de los parentales son:

- pp (homicigota dominate con flores púrpura)

- bb (homocigota recesivo con flores blancas)  

Explanation:

Alelos:

p: púrpura y b: blanco

Genotipos parentales:  

- pp: homocigota dominante (flores púrpura)

- bb: homocigota recesivo (flores blanca)

Cruzamiento parental: pp X bb

F1: 100% pb  

Cruzamiento F1: pb X pb

F2: 25% pp (flores púrpuras), 50% pb (flores púrpuras) y 25% bb (flores blancas)

En este caso, el alelo que determina el color púrpura es dominante sobre el alelo que determina el color blanco. Es por esta razón que en la F1 todas las plantas heterocigotas exhiben un fenotipo con flores púrpura. En la F2 la proporción fenotípica será 1:2:1 (1 homocigota dominante, 2 heterocigotas y 1 homocigota recesivo), mientras que la proporción genotípica será 3:1 (3 plantas con flores púrpuras y 1 planta con flores blanca).

Answer:

Explanation:

The antidote entered into Jared's cell and targeted the cyanide that was disrupting his Electron Transport Chain. The antidote changes the cyanide into a molecule called thiocyanate. Jared’s body can now remove this molecule through his excretory system. As the cyanide is removed, electrons can now leave the ETC by reacting with O2 to make water. His ETC can now get new electrons from NADH this then means he is able to move more H+ into the inter-membrane space. Jared’s cells can now make ATP again.

The antidote binds cyanide. This binding impedes cyanide to inhibit the cytochrome oxidase action. As the cytochrome reactivates, electron transport reactivates as well, and ATP is synthesized again.  

---------------------------------------------------------------------

Ion cyanide inhibits cellular respiration by binding to the ferric ion of cytochrome oxidase and blocking the electron transference.

Because the electron transporter chain is interrupted, there is no ATP production, and muscles do not get enough energy.

The antidote enters Jared's cells and targets cyanide.

When the antidote meets cyanide, it binds to this last one and blocks its effect on cytochrome oxidase.

As cyanide can no longer bind the ferric ion of cytochrome oxidase, the enzyme remains active, and the electron transport is reactivated.

As electrons move along the chain, protons are pomped to the intermembrane space.

ATP production reactivates again as well because the proton gradient is used to produce ATP molecules.

Explanation:

If originally, sedimentary rocks are exposed to energy from the sun, no changes will occur to them.

One will hardly spot any difference in their mineralogical composition as such.

Igneous rock will be produced from the sedimentary rock if the sedimentary rock was exposed to energy from Earth’s interior for millions of years.

The temperature of the sun does not make any significant changes on sedimentary rocks.

Answer: the sequence of three bases that codes for a specific amino acid

Explanation: I took the test and i got this answer correct so i hoped this helped!!

Codons are generally a sequence of three bases in the DNA and RNA that codes for specific amino acids. So option C is correct.

A genetic code is a set of information that helps to convert the genetic information stored inside the genetic material into a defined sequence of amino acids called a protein.

Though the DNA has nucleotide sequences that contain information for producing the proteins, the DNA cannot directly synthesize the proteins. It is first converted to mRNA in order to be translated into a specific protein.

There are in total 64 codons, out of which 61 code for specific amino acids while the remaining three codons are known as stop codons and are used in terminating the process of translation of proteins.
