Explanation:

Nitrogen fixing bacteria: They are defined as the micro-organism which are capable of transforming atmospheric nitrogen into fixed nitrogen, this nitrogen is used by living organisms. They are basically two types:

1) One is free living bacteria such as blue-green algae (cyanobacteria), Azotobacter, and Clostridium.

2) Second is symbiotic bacteria such as Rhizobium which are symbiotic relationship with leguminous plants.

The variable affecting the enzyme action is temperature.  

Catalase is the enzyme which acts upon the "substrate hydrogen peroxide", breaking down them into water and oxygen gas.  Each and every enzyme is a protein, which has a tertiary structure which is essential for the enzyme action. The tertiary structure of the enzyme provides the site of enzymatic action where the substrate do gets attached for the enzymatic action to take place.  

Temperature, or heat, changes the protein structures irreversibly after a certain range. So if the beef liver is boiled, then the enzyme structure gets permanently changed, which is why the catalase cannot breakdown the peroxides, after boiling.  

In the given experiment, the variable affecting enzyme function is temperature. The high temperatures achieved through boiling lead to the denaturation of the catalase enzyme in the beef liver, thus inhibiting its ability to breakdown hydrogen peroxide.

In this experiment, the variable affecting enzyme function is the temperature. By boiling the beef liver, which contains the enzyme catalase, the heat alters the enzyme's shape or denatures it, thereby inhibiting its ability to function and interact effectively with its substrate - hydrogen peroxide. Enzymes like catalase are proteins, and their functionality is deeply tied to their structure. When the structure is altered due to high temperatures as in this case, the enzyme loses its ability to catalyze the reaction - hence, no breakdown of hydrogen peroxide.

The factor affecting the enzyme's activity here - temperature - is what is referred to as an environmental condition that impacts enzymatic function, alongside others such as pH and substrate concentration.

Answer:Spurs on it's hindlimbs

Explanation:the duck-billed platypus is has Spurs on it's hindlimbs that's secretes venom.this venom is for mating purpose and it's present only in males

The male duck-billed platypus has sharp spurs on its hind legs that deliver venom, causing severe pain and swelling. This is mainly used during territorial disputes in the mating season.

The duck-billed platypus delivers its venom through a pair of sharp spurs on the hind legs near the ankle, which are connected to a venom-producing gland in the thigh. This venom consists of a mixture of neuroactive peptides, which are short proteins. The male platypus uses his venomous barbs predominantly during mating season when competing for territory. While not typically lethal, a platypus's venom can cause severe pain and swelling that persists for an extended period.

Answer:

b. Synergistic dominance

Explanation:

The stabilizing muscles will always be synergistic, since only from the synergies (hence the term synergist) that arise from joint work is efficient and controlled movement possible. However, not all synergists will be stabilizers. Stabilizer will be one that, thanks to the geometric arrangement of its fibers, will have the ability to maintain alignment in the joint and stable the axis of rotation.

In the case of knee extension, we would have as stabilizers all the antagonists who, because the flexion axis is virtual and not physical, must maintain the stability of said axis. If the axle were physical, such as the wheel in a horse carriage, or on a skateboard through the bearings, the antagonistic muscles would not be necessary for this purpose, because the fixed axis would maintain the position. Since the joints of living beings do not have a fixed physical axis, it is the muscles themselves, specifically the antagonists, who must be responsible for maintaining the stability of the joint creating a virtual axis on which rotation occurs.

Question: All your cells contain proto-oncogenes, which can change into cancer-causing genes. Why do cells possess such potential time bombs?

A. Cells produce proto-oncogenes as a by-product of mitosis.

B. Proto-oncogenes are necessary for the normal control of cell growth and division.

C. Proto-oncogenes protect cells from infection by cancer-causing viruses.

D. Proto-oncogenes are unavoidable environmental carcinogens.

E. Proto-oncogenes are genetic junk that has not yet been eliminated by natural selection.

Answer:

B. Proto-oncogenes are necessary for the normal control of cell growth and division.

Explanation:

The process of cell division is under tight regulation by a family of extracellular growth factors, specific proteins that trigger cell division and the tumor suppressor genes that normally inhibit cell division. Defects in these genes can lead to cancer.  

For example, the protein encoded by tumor suppressor gene p53 stimulates the synthesis of p21 which in turn inhibits the cyclin-cdk2 to block entry of G1 cells into the S phase until the DNA is repaired. Mutations in tumor suppressor genes retinoblastoma and p53 allow cells to proceed to the S phase irrespective of DNA repair.

Likewise, a mutation in ras proto-oncogene encodes a protein with no GTPase activity. The mutant Ras protein is always in its activated form, regardless of the signals from normal receptors. This makes the cells to divide in an uncontrolled manner.  

Proto-oncogenes are genes essential for normal cell function, however, when mutated, they may cause uncontrolled cell division leading to cancer. Other factors, such as underactive tumor suppressor genes and epigenetic changes, can also contribute to cancer development. Active research is underway to utilize the reversibility of these changes for cancer treatment.

Every cell in our body contains proto-oncogenes, which are essential for normal cell function and growth. However, these can mutate into oncogenes, setting off the equivalent of biological 'bombs' by causing uncontrolled cell proliferation, leading to cancers such as Burkett's Lymphoma. Proto-oncogenes and tumor suppressor genes work in tandem, like the accelerator and brakes of a car, to control cell cycle. Unwanted cell division and proliferation can occur due to three main scenarios: proto-oncogenes becoming overactive, tumor suppressor genes becoming underactive, or through epigenetic alterations.

Epigenetic changes such as methylation and deacetylation can silence genes, and these changes are common in cancer. Because these changes are temporary and reversible, designing drugs and therapies that can reverse these changes is an area of active research in cancer treatment.

Other proteins that influence the cell cycle, in addition to cyclins and cell-surface receptors for growth factors, have potential oncogenetic properties. An example is the Cdk gene, which when altered, can speed up cell cycle progression.

Answer:

9:3:3:1   ( 9 dominant pod color and shape, 3 heterozygous pod color and  homozygous recessive pod shape, 3 homozygous recessive pod color and heterozygous  pod shape and 1  recessive homozygous pod color and pod shape)

Explanation:

Mendel's law of independent assortment posits that the alleles of two (or more) different genes get assorted into gametes independently of one another. This implies that the allele  a gamete receives for one gene does not influence the allele received for another gene.

In the question  given;

We will take a critical look at the  cross between  two pure-breeding pod color and pod shape:

Pod color (green) = C

Pod color (yellow) = c

Pod Shape (smooth) = S

Pod shape (constricted) = s

The F1 progency of the cross between the heterozygous pod color and pod shape will be:

Cc  × Ss

= CS, Cs, cS, cs

From the question, we are to complete the punnett square of the results of the F1 generation, i.e if the F1 progeny assorts independently, what will be the results (F2 generation)

 i.e :  CS, Cs, cS, cs × CS, Cs, cS, cs

The Punnet Square is in the attached file below.

The results of this dihybrid cross are as follows:

CCSS, CCSs, CCSS, CcSs, CCSs, CcSs, CcSS, CcSs, CcSs  (all dominant pod color and shape) "9"

CCss, Ccss, Ccss  (heterozygous pod color and  homozygous recessive pod shape) "3"

ccSS, ccSs, ccSs (homozygous recessive pod color and heterozygous pod shape)

ccss (recessive homozygous pod color and pod shape)

We can therefore conclude that the results of the Punnet Square of the F1 generation is in the ratio of 9:3:3:1

Answer:

The correct answer is- Leukopenia

Explanation:

White blood cells are present in our blood which protect our body from foreign antigens like bacteria, viruses, etc. When these white blood cells decrease abnormally in number then this condition is called leukopenia.

White blood cells contain different cell which protect our body from different type of infections. So there are different types of leukopenia according to the particular white blood cell whose number became low.

For example when neutrophils number in the body decrease it is called neutropenia. So the correct answer is leukopenia.

Leukopenia is the term for an abnormally low white blood cell count which increases individual's risk for disease due to immune system weakness.

The term for an abnormally low white blood cell count is Leukopenia. This condition occurs when too few leukocytes (white blood cells) are in the blood. A low white blood cell count leaves the individual at a higher risk for disease since these cells play a significant role in the immune system. Their production begins in the bone marrow, and abnormalities with this can cause deficient counts. Matters are further complicated when abnormally low lymphocyte counts occur, as a result of chronic illness or immunosuppression.

Answer:

D (Cell gamete)

Explanation:

A gamete is a sex cell while the other three cells in the options are somatic or body cells. The bone, kidney and nerve cells are regular types of body cells that do not perform any reproductive function. Hence, they contain two set of chromosomes (diploid) since they replicate through mitosis, which is a kind of cell division that gives rise to daughter cells with identical genetical composition. The animal has a diplontic life cycle, meaning that it is a diploid organism, hence it undergoes mitosis in its somatic cells to produce diploid somatic cells, which has the same genetic composition as the parent cell.

On the other hand, gametes are sex cells that arise from the meiotic division of reproductive cells. Meiosis, in contrary to mitosis, is a type of cell division that produces daughter cells with a reduced number of genetic material (chromosomes). The reproductive cells of a diploid (2n) animal undergoes meiosis to produce haploid (n) gametes (sperm in male, egg in female). These gametes contain half the number of chromosomes as the parent cell, making them genetically different from the parent cell.

These haploid gametes (sperm and egg) fuse together to result into a diploid organism.

Answer:

The correct answer is A. breaking down organic matter

Explanation:

Bacteria and archaea are the domains that come under prokaryotes. These organisms lack nucleus. They play an important role in the nutrient cycle. Most of these organisms are heterotrophs and consume organic matter to gain energy.

They play an important role in breaking down the organic matter and releasing the nutrient from them in the environment so they helps in circulating the nutrients in the ecosystem.

For example, different methanogens and acid-forming bacteria decompose organic waste of industry and agriculture and produce manure and biogas during anaerobic decomposition. So the correct answer is A.

The primary ecological role of prokaryotes is to break down organic matter, which is crucial in the carbon and nitrogen cycles for maintaining balance within ecosystems.

Primary Ecological Role of Prokaryotes

The primary ecological role of prokaryotes is breaking down organic matter. Prokaryotes are essential in nutrient cycling, particularly in the carbon and nitrogen cycles. They decompose dead organisms, returning vital nutrients to the environment, and fix nitrogen to make it accessible to plants. Additionally, some prokaryotes are involved in bioremediation, where they clean up pollutants from the environment. Prokaryotes also contribute to the production of oxygen and some even inhabit human bodies, providing health benefits and aiding digestion. In ecosystems, they play various roles that are critical to maintaining the balance and supporting life.

Answer:

The correct answer is- Histone

Explanation:

DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.

Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.

DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.

Answer:

D - Its genetic diversity is very low

Explanation:

An extinction vortex can be defined as the process which populations in decline pass through to drive them into a vortex of smaller populations, endangering their survival as they tread the path to extinction.

Populations that fall to extinction vortex already have small populations which is usually as a result of certain powerful genetic factors, which cause the populations to continue to decline in size.

During genetic drift which occurs in all populations, small populations tend to lose genetic diversity as a result of the random nature of gamete sampling.

This is because any change in alleles in a small populations can have dastardly effects on the populations size due to a small gene pool.
