Answer 1

Answer:

detail is given below

Explanation:

We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. Proton has positive charge  P⁺   and neutron is neutral  n⁰ .

The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The number of protons and electrons are always equal to make the atom electrically neutral and when an atom loses its valance electron the number of protons increases and thus positive charge increased and atom form cation.

Cation formation:

X → X⁺ + e⁻

When an atom gain electron negative charge increase because of more number of electron thus atom form negative ion or anion.

Anion formation:

X + e⁻ → X⁻

1) If an atom loses an electron, it becomes... (positive ion)

2) If an atom gains an electron, it becomes... (negative ion)

3) A hydrogen atom loses an electron. It becomes...(positive ion)

4) A sodium ion (Na) can ionically bond with which?

Sodium ion (Na⁺) can ionically bonded with Cl⁻ , thus both form salt which sodium chloride. Sodium ion can not bonded with hydrogen and potassium because both are also form cation.

5) If an atom gains or loses a neutron, the charge of that atom changes.

The given statement is false because neutron is neutral so when it added or removed from an atom there will be no effect on charge.

6. If an atom gains or loses an electron, the atomic mass of that atom changes.

The given statement is also false because atomic mass is sum of number of neutron and protons. So when electron is added or lost by an atom there will be no effect on atomic mass.

7. If an atom gains or loses a neutron, the atomic mass of that atom changes.

The given statement is true. Atomic mass is sum of number of neutron and protons. So when neutron is added or lost by an atom there will be effect on atomic mass. The atomic mass will be increase or decreased.

8. An atom with  valence electrons can covalently bond with another atom.

The given statement is true. The valance electrons of an atom are involved in bonding. It could ionic, covalent or any other type.

Answers

Most digestion in humans occurs in the first 25 centimeters of the 6-meter length of the small intestine called the duodenum.

What is digestion?

In order to be absorbed into the watery blood plasma, large, insoluble food molecules must be broken down into smaller, water-soluble food molecules during digestion. These tiny molecules enter the bloodstream through the small intestine in some organisms. Based on how food is broken down, digestion, a type of catabolism, is sometimes separated into two processes: mechanical digestion and chemical digestion.

When a huge food item is physically broken down into smaller bits so that digestive enzymes may reach them, this process is referred to as mechanical digestion. Mastication in the mouth and segmentation contractions in the small intestine are two examples of mechanical digestion. Enzymes break down food into little molecules that the body can use during chemical digestion.

spontaneous activity of the mitochondrial apoptosis pathway drives chromosomal defects, the appearance of micronuclei and cancer metastasis through the caspase-activated dnase

Answers

In cancer cells, there are smaller nuclei called micronuclei that store DNA. The immune sensor axis GAS/STING recognizes micronuclei, promoting the spread of cancer. By experimentally activating the mitochondrial apoptosis system to a non-apoptotic level, Caspase-activated DNA can cause the emergence of micronuclei (CAD). Micronuclei and chromosomal misalignments were decreased in tumor cell lines and intestine organoids by inhibiting mitochondrial apoptosis or CAD, respectively. Blocking mitochondrial apoptosis or removing CAD decreased. As a result, low-level mitochondrial apoptosis machinery activity affects cancer metastasis significantly through activating STING and CAD-dependent gene induction.

Answers

To pass from the blood into the capsular space in the renal corpuscle, the substance must pass through the capillary endothelium, the basement membrane, and the podocytes.

To pass from the blood into the capsular space in the renal corpuscle, the substance must pass through the capillary endothelium, the basement membrane, and the podocytes.

The renal corpuscle is the initial part of the nephron in the kidney where blood filtration takes place. The glomerular capillaries in the renal corpuscle are surrounded by three layers: the capillary endothelium, the basement membrane, and the podocytes.

The capillary endothelium is the innermost layer of the glomerular capillaries and consists of a single layer of endothelial cells. The basement membrane is a thin layer of extracellular matrix that surrounds the capillary endothelium. The podocytes are specialized cells that have foot-like projections called foot processes that wrap around the capillaries and form filtration slits.

As blood flows through the glomerular capillaries, small molecules such as water, electrolytes, and waste products are able to pass through the capillary endothelium and basement membrane. However, larger molecules such as proteins and blood cells are generally too large to pass through these layers.

The podocytes further regulate the filtration process by controlling the size of the filtration slits between their foot processes. This helps to prevent larger molecules from passing through into the capsular space.

In summary, to pass from the blood into the capsular space in the renal corpuscle, the substance must pass through the capillary endothelium, the basement membrane, and the podocytes

what is the correct order of protein production?
1) ribosome
2) endoplasmic reticulum
3) secretory vesicles
4) golgy apparatus

a) 1,2,3,4
b) 2,4,3,1
c) 1,2,4,3
d) 3,2,4,1

Answers

Answer:

The correct order of protein production is:

c) 1,2,4,3

Ribosome: Protein synthesis begins in the ribosomes, which are located either in the cytoplasm or attached to the endoplasmic reticulum.

Endoplasmic Reticulum: After the initial stages of protein synthesis in the ribosomes, the newly synthesized protein is transported into the endoplasmic reticulum (ER) for further processing and modification.

Golgi Apparatus: The proteins synthesized in the ER undergo further processing and modifications in the Golgi apparatus. This includes sorting, packaging, and modifying the proteins to their final functional forms.

Secretory Vesicles: Once the proteins are properly processed and modified in the Golgi apparatus, they are packaged into secretory vesicles. These vesicles transport the proteins to their destination, such as the plasma membrane for secretion outside the cell.

Therefore, the correct order is 1, 2, 4, 3.

Answer:

The correct order of protein production is ribosome, endoplasmic reticulum, Golgi apparatus, and secretory vesicles. So the correct answer would be c) 1,2,4,3.

Many proteins destined for the endoplasmic reticulum, the Golgi apparatus, lysosomes, the plasma membrane, and secretion from the cell are synthesized on ribosomes that are bound to the membrane of the endoplasmic reticulum. The Golgi apparatus then distributes these proteins and lipids that it receives from the ER.

Answers

A pathogenicity island is a segment of a microbial chromosome that contains virulence genes. These genes enable the microbe to cause disease in a host organism. When analyzing a microbial genome, there are several indicators that can suggest the presence of a pathogenicity island. However, one of the options provided in the question is NOT a good indication of a pathogenicity island.

One indication of a pathogenicity island is a GC/AT ratio that is different from the rest of the chromosome. Pathogenicity islands often have a higher or lower GC/AT ratio than the surrounding genomic region. This is because pathogenicity islands often have a different evolutionary origin than the rest of the chromosome.

Another indication of a pathogenicity island is the presence of clusters of virulence genes. These genes may be unique to the pathogen or may be present in other related organisms that also cause disease.

In summary, a pathogenicity island can be identified by several indicators, including a different GC/AT ratio, the presence of clusters of virulence genes, and the flanking of residual phage genomes. However, the presence of RNA nucleotides alone is not a good indication of a pathogenicity island.

what is the role of messenger rna in protein synthesis

Answers

The role of messenger RNA (mRNA) in protein synthesis is to carry the genetic information from the DNA to the ribosomes, where it serves as a template for protein synthesis. mRNA is transcribed from the DNA in the nucleus during a process called transcription.

After transcription, the mRNA molecule carries the genetic code, which consists of a sequence of nucleotides (adenine, cytosine, guanine, and uracil), to the ribosomes in the cytoplasm. The sequence of nucleotides in the mRNA is a complementary copy of the DNA sequence, with uracil (U) replacing thymine (T).

At the ribosomes, mRNA acts as a messenger or intermediary between the DNA and the synthesis of proteins. The ribosomes read the sequence of nucleotides in the mRNA and use it as a blueprint to assemble amino acids in the correct order, forming a polypeptide chain. This process is called translation.

The process of fusing two or more DNA molecules to produce a hybrid is known as recombinant DNA. Restrictions endonucleases and ligases are two classes of enzymes that enable the technique.

When a restriction endonuclease detects a particular DNA sequence, it makes cuts inside or near that sequence. The recognition sequence of a restriction enzyme will haphazardly appear on every (1–4)n bases along a random DNA chain. The equation states how many fragments ends (measured in moles) are produced when a restriction enzyme cuts DNA.

Moles of DNA ends =2x(grams of DNA)/(number of bp)(660 g/mol / bp).

The equation describes how many ends are produced when circular DNA is digested by a restriction enzyme.

Mole ends=2x(moles DNA)x number of restriction sites.

Answers

When potassium channels open and potassium rushes out of the cell, it triggers a hyperpolarization phase in the action potential.

When potassium channels open and potassium rushes out of the cell, it triggers a hyperpolarization phase in the action potential. This occurs after the depolarization phase, where sodium channels open and sodium rushes into the cell. During the hyperpolarization phase, the membrane potential becomes more negative than the resting potential, making it less likely for the neuron to fire again. This is due to the high concentration of potassium ions outside the cell and the low concentration inside, creating an electrochemical gradient that drives potassium out of the cell. The steps of this process involve the opening of potassium channels, the movement of potassium ions down their concentration gradient, and the restoration of the resting membrane potential.

Answers

Nitrifiers are bacteria that generate nitrites or nitrates. The correct option is (a)  

Nitrifiers are a group of bacteria that play an important role in the nitrogen cycle by converting ammonia (NH₃) into nitrites (NO₂⁻) and nitrates (NO₃⁻) through a process called nitrification.

This process is important for the cycling of nitrogen in ecosystems, as it converts ammonia, which is toxic to most plants, into forms that can be readily taken up and used by plants.

Nitrification is a two-step process, with ammonia being first oxidized to nitrite by bacteria such as Nitrosomonas and Nitrosococcus, and then further oxidized to nitrate by bacteria such as Nitrobacter and Nitrospira. Without nitrifying bacteria, the nitrogen cycle would be incomplete, and the availability of nitrogen for plant growth would be severely limited.
