Why is an atom said to be electrically neutral? Please i need further explanation​

Answers

Answer 1
Atoms are electrically neutral because they contain equal quantities of positively charged protons and negatively charged electrons. Electrons and protons have equal but opposite charges, so the result is no net charge.

how will you explain the importance of it in completeness of the biological organization?

Answers

The importance of biological organization is that it allows the study of natural balance between all organisms in a simple way.

The biological organization is a biological term that refers to the hierarchy of complex biological structures and systems that define life through a reductionist approach.

In this form of organization, the traditional hierarchy begins in the atom, this being the lowest level, and ends in the biosphere as a superior system.

The integrality of this organization focuses on the reciprocal relationships between each level, because the higher levels are more complex, but contain each of the organisms and parts that make up the lower levels. This type of organization must be understood as a whole.

Answers

Answer:

more active transport occurs in cell A then cell B

Explanation:

hope this helps ;)

The possible conclusion that can be made drawn about the activity of these two cells is that more active transport occurs in cell A than in cell B. The correct option is B.

What is transport?

Active transport is a type of transport that cells use to move molecules up and down cell membrane concentration gradients.

Moving actively is carried out using a variety of membrane proteins known as carrier proteins that are connected to an energy source, such as ATP, for example.

The energy needed to move molecules or ions up or down a concentration gradient is provided by the hydrolysis of ATP during this process, known as active transport. The other transport is passive transport, which is reverse.

Therefore, the correct option is B. more active transport occurs in cell A than in cell B.

The connective tissue layer that surrounds an entire muscle is called ______. Multiple choice question. epimysium endomysium perimysium

Answers

Answer:

the answer is epimysium

Explanation:

The connective tissue layer that surrounds an entire muscle is called the epimysium, which is the first option as it is composed of dense, irregular connective tissue and serves to protect the muscle.

What is epimysium?

The epimysium plays a role in transmitting force from the muscle to the surrounding structures and connects to the tendons and other connective tissues that attach the muscle to bone and other structures, and the epimysium is just one of the three connective tissue layers that make up the structure of a skeletal muscle; the other two layers are the perimysium and the endomysium, and together, these three layers of connective tissue provide the necessary structural support for skeletal muscles to function properly.

Hence, the connective tissue layer that surrounds an entire muscle is called the epimysium, which is the first option.

Which Organelle assembles amino acids to create proteins?

A. Ribosome
B. Lysosome
C. Chrolorplast
D. Cell membrane

Answers

The answer should be A - Ribosome because during protein synthesis, ribosomes assemble amino acids into proteins and ribosome’s are the cellular structures responsible for protein synthesis.

hope this helps!

Ribosomes assembles amino acids to create proteins. The correct option A.

Ribosomes are the organelles responsible for assembling amino acids to create proteins in cells. Ribosomes are composed of RNA and proteins, and they exist either freely in the cytoplasm or attached to the endoplasmic reticulum (ER).

During protein synthesis, the ribosomes read the genetic information encoded in mRNA (messenger RNA) and facilitate the process of translation. Transfer RNA (tRNA) molecules transport amino acids to the ribosomes, where they are joined together in the correct sequence to form a protein chain.

Thus, the ideal selection is option A.

In translation, the dehydration synthesis reaction is catalyzed by DNA polymerase enzyme. Therefore, the correct option is B.

What is DNA polymerase?

DNA polymerases are a group of enzymes that are responsible for catalyzing the synthesis of DNA. Their main function is to replicate the DNA. These enzymes work in pairs and a responsible for replicating two strands of DNA  in a tandem. DNA polymerases α and δ are primarily responsible for nuclear DNA replication. There are at least 15 DNA polymerases known to exist in humans.

Translation is the process by which the genetic code carried by mRNA is decoded to produce a specific sequence of amino acids that will form a protein. This process involves the ribosome, which is responsible for assembling the protein chain by joining amino acids in a specific order dictated by the mRNA sequence. Therefore, the correct option is B.

A 15 °C and 35 °C B
35 °C and 45 °C C
35 °C and 55 °C D
45 °C and 55°C

Answers

Answer:D

Explanation:

The optimum temperature for the enzyme is between 45 °C and 55°C. Therefore, option (D) is correct.

What is an optimum temperature for enzyme?

Most enzymes perform best at a temperature of around 98.6 degrees Fahrenheit (37 degrees Celsius). Additionally, some enzymes function well both at low and high temperatures. For instance, while animals in desert climates have enzymes adapted to higher temperatures, those in the Arctic have them adapted to lower optimal temperatures.

The reaction rate will accelerate as more hydrogen peroxide is added to the mixture because more substrate molecules can interact with the enzyme and produce more product as a result. As you increase the amount of H2O2 in your reaction, more foam is generated in your cup as a result.

This human disorder, called Ambra's Syndrome, shows X-linked dominant inheritance. The
mother of the boys is also affected by Ambra's Syndrome, although her excessive hair growth
occurs in various, scattered patches on her skin rather than a continuous coverage like her sons.
What is the most likely explanation for the patchy expression of hairlessness on the mother's
skin?

Answers

The most likely explanation for the irregular expression of hairlessness on the mother's skin is codominance

Codominance is a biological term to refer to the hereditary pattern that is characterized by:

In the heterozygous state, there is no recessive allele, but both behave as dominant. Codominance is characterized by the manifestation of both characteristics as dominant, without mixing.

According to the above, the irregular expression of the lack of hair in the mother is a manifestation of the codominance of the hair gene and the hairless gene that do not mix but are seen independently.

No

Arteries typically carry oxygenated blood, which is bright red in colour. The exception is the pulmonary artery which carries deoxygenated blood from the heart to the lungs.

Answer:

Venules carry deoxygenated blood. All blood in humans is bright red when oxygenated, but, a darker red when deoxygenated. Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated).
