Answer:

The splitting of a uranium atom releases energy. This process is called “nuclear fission”, since the centre of an atom is called its nucleus. When a uranium atom splits it gives off more neutrons, which can then split more atoms, and so the energy level rapidly multiplies

Explanation:

The splitting of a uranium atom releases nuclear energy by the process called nuclear fission, releases more neutrons, which can then split atoms, and energy level multiply rapidly.

The Energy is stored in the core of atom  called nuclear energy.

The mass of an atom refers to the mass of nuclear elements like total mass of neutron and proton present in it.

Nuclear reaction can either be nuclear fission or fusion which releases  the nuclear energy.

The process in which atoms combine to form a larger atom called nuclear fusion, while the process in which the the breakdown of atoms with the release of energy called nuclear fission.

Nuclear power plants produce energy by nuclear fission where as Sun produces energy by nuclear fusion.

Answer: False

Explanation: I think it's false because, hurricane damages are caused by storm surges, strong winds and associated tornadoes.

Answer: The options are not given, here are the options.

A. One species is much better competitor than the other.

B. Periodic disturbances allow for coexistence.

C. Two species tended to use different resources.

D. The two species experienced interference competition and not exploitative competition.

The correct option C.

Two species tended to use different resources.

Explanation:

From Gause experiments on competing paramecium pairs, He found out that most times both species persisted and sometimes only one did because the two species uses different resources.

Organisms normally compete for limited resources in order to survive and one intend to compete well while other suffer. Both in the case of competing paramecium pairs, the pair use different resources which make the to persist and survive well. Once the resource of one finishes, the other one will persist because it is still surviving on its available resources.

Answer:

180,000 nucleotide pairs = 180 kilobase pair (kbp) =  0.18 Megabase pairs (Mbp)

Explanation:  

Synthesis rate = 1,000 nucleotides (nts) x second

1 minute = 60 seconds  

30 minutes = 60 x 30 = 1,800 seconds

>> 1,800 seconds x 1,000 nuleotides per second = 180,000 nts  

A typical bacterial genome contains approximately 5 Mbps of DNA that conforms a circular chromosome localized in the cytoplasm. In consequence, in this case the bacterial genome is small (0.18 Mbp).

DNA replication is a process in which the fragment gets replicated to form two indistinguishable replicas of itself. It is vital for the growth and passing of hereditary information to the newly produced daughter cells.

180,000 nucleotide pairs are formed in the replicating bacteria.

This can be calculated by:

[tex]\text{Synthesis rate} & = 1,000 \;\text{nucleotides (nts)} \times \text{ second}[/tex]

[tex]\text{1,800 seconds} \times \text{ 1,000 nucleotide per second} & = 180,000 \;\text{nts}[/tex]

The bacterial genome thus produced will have 180,000 nucleotide pairs or 180 kilo-base pairs (kbp) or 0.18 Megabase pairs (Mbp) in the chromosome.

Answer:

Its Eurasian

Explanation:

This boundary is between the African Plate and the Eurasian Plate.

This boundary is known as a convergent plate boundary. Convergent plate boundaries occur when two tectonic plates move toward each other.

In the case of the African Plate and the Eurasian Plate, they are colliding, and one plate is being forced beneath the other in a process called subduction.

As the plates converge, the intense pressure and friction cause seismic activity, leading to earthquakes and volcanic eruptions in the region.

These collisions also result in the formation of mountain ranges, such as the Himalayas, as the crust is pushed upward and folded.

Studying this convergent plate boundary is essential for understanding the geological processes shaping our planet's surface and the associated hazards like earthquakes and volcanoes.

Answer:

The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.[

Explanation:

Answer: It has peptidoglycan

Explanation:

The kingdom Eubacteria is the domain of prokaryotic bacteria. These are unicellular and prokaryotic organisms. Their cell membrane is made up of lipids. The cell wall is made up of peptiodoglycan which gives rigidity to the cell wall. It gives the structural strength to the bacterial cell wall, gives the strength to the bacteria, and it will counteract the osmotic pressure develop in the cytoplasm.

Lactobacillus acidophilus possess the peptidoglycan in the cell wall this establishes its relationship with kingdom Eubacteria.

Answer:

The ATPs produced during Chemeiosmosis, in the chloroplast is needed during Calvin cycle to fix carbon for production of CHO, protein and fats  during conversion of 3C-glyceride phosphate(GP) to 2C- triose phosphate.(TP) .

The ATPs is needed for this reduction to take place in the presence of NADPH(which is oxdized to NADP).

Therefore, if the final electron acceptor is removed, there will be no electron transport chains which generated the PMF, for pumping H+ across into the thylakoid membrane of the chloroplast, to generate the electrochemical gradients, needed for  the energy for ATPase synthase enzymes,to synthesize ATPs production.

Therefore, the removal of the electron acceptor (oxygen) leads to stoppage of electron transport chain, and hence loss of ATP s, and therefore, no Carbon fixation as CHO, or protein, or fats.

The correct answer is "strengths: inexpensive, easy to culture, short life cycle, large number of offspring; weaknesses: invertebrate model, some diseases such as immunological cannot be modelled, anatomical features are very different from humans"

Explanation:

The fruit fly Drosophila melanogaster is one of the most used animal model for genetic and biomedical studies. There are many advantages of using Drosophila as model, including that it is very inexpensive to handle, it is easy to culture, it has a short life cycle allowing to observe the changes in phenotype very quickly and its large number of offspring allows to include several repetitions per trait in a study. However, there are some weaknesses of using Drosophila to study human biology. First, obviously the fruit fly is very different from humans, it is an invertebrate and its anatomical features are very different, which makes impossible to model some disorders such as immunological diseases.

Answer:

Explanation:

If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have

2 possible gametes for each five = 2 to the power of 5 = 32 gametes

Then genotypes = 3 to the power of 5 = 243

The same also for 10 genes

2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes

Then genotypes = 3 to the power of 10 = 59,049

The same also for 20 genes

2 possible gametes for each 20 = 2 to the power of 20= 1,048,576

Them genotypes = 3 to the power of 20 = 3,486,784,401

Many traits (phenotypes), like eye color, are controlled by multiple genes. In the following scenario, the number of genes are:

a. 5 Genes: 243 genes

b. 10 Genes: 59,049 genes

c. 20 Genes: 3,486,784,401 genes

Genes are small hereditary materials bound in tiny beads like fashion and make a chromosome.

Now, the number of genes in the given scenario is:

a. 5 Genes: If there are 5 genes, let us assume that they are in the alternative forms, with 2 possible gets for each five.

So, 2 possible gametes for each five = 2 to the power of 5 = 32 gametes

The genotypes combinations = 3 to the power of 5 = 243

b. 10 Genes: 2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes

The genotypes combinations = 3 to the power of 10 = 59,049

c. 20 Genes: 2 possible gametes for each 20 = 2 to the power of 20 = 1,048,576

The genotypes combinations = 3 to the power of 20 = 3,486,784,401

Therefore, the number of genes is:

a. 5 Genes: 243 genes

b. 10 Genes: 59,049 genes

c. 20 Genes: 3,486,784,401 genes
