Answer:

an identical copy of the parent cell’s primary DNA

Explanation:

In this form of cell division, a cell replicates its DNA, increases in size, and divides into two daughter cells. Each daughter cell receives one copy of the replicated parental DNA.

During binary fission (d), daughter cells receive an exact copy of the parent cell's main DNA.

Definition. Deoxyribonucleic acid, commonly known as DNA, is indeed the molecule that contains the genetic information necessary for an organism's growth or operation. The structure of DNA consists of a double helix, which is made up of two linked threads that loop around one another to form a twisted ladder.

Many people think that the 1950s saw the discovery of DNA by English physicist Francis Crick & American biologist James Watson. This isn't in fact the case. Rather, Swiss chemist Miescher made the first official discovery of DNA in the late 1860s.

Answer:

The correct answer is - 3.3 g/L.

Explanation:

It is known that if endogenous metabolism is not important then,

µnet = µmax = 0.693/doubling time.

Given:

doubling time = 6.5 hr, therefore,

µmax = 0.693/6.5 = 0.1/h

Formula:

First, maximum dilution rate Dmax,

Dmax = µmax*[S0]/{Ks + [S0]}.........(1)

Steady-state cell concentration, X

X = Yx/s{[S0] - KsD/(meumax - D)..........(2)

Solution:

Yx/s = 0.33 g/g-substrate;

Ks = 12 x 10-3 g/L; [S0] = 10g/L,

puting value in (1)

Dmax = 0.1 * 10 / (12 x 10-3 + 10)

= 0.1/h.

Now it is given that operating D is 1/2 of Dmax, therefore,

D in our case will be = 0.05/h

concentration of protozoa cells from equation (2).

Therefore, X = 0.33*{10 - 12 x 10-3 * 0.05/(0.1 - 0.05)} = 3.3 g/L.

Answer:

Animal cell

Explanation:

Answer:

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.

Conventionally, a positive charge would go in the same direction as an electric current. As a result, the battery's positive terminal receives less current in the external circuit than its negative counterpart. Actually, electrons would go in the reverse direction across the cables.

A stream of charged particles, such as electrons or ions, traveling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated.

The cell phone, trains, ships, refrigerator, and the motors in appliances like food processors all run on electricity. To be useful, electric energy must be converted into other forms of energy like heat, light, or mechanical.

Conventionally, a positive charge would go in the same direction as an electric current. As a result, the battery's positive terminal receives less current in the external circuit than its negative counterpart.

Answer:

beaks

Explanation:

Answer:

The diagram below represents some stages in the life cycle of humans. The numbers in the diagram represent various processes in the cycle.

1. "The processes reduce the amount of genetic information from each parent by half."

During sexual reproduction, a specialized cell division process called meiosis occurs. Meiosis involves two consecutive divisions, resulting in the production of four haploid cells (gametes) from a diploid cell.

2. "Each parent only contributes half of the genetic information that is contained in his or her own cells."

As mentioned earlier, meiosis results in the formation of haploid gametes. Each gamete contains only one set of chromosomes, which is half the number found in the parent's diploid cells.

During meiosis, homologous chromosomes pair up, and genetic recombination occurs between them, shuffling and exchanging genetic information.

3. "Each egg (or each sperm) will carry only half of the genetic information contained in the parent's body cells."

This statement reiterates that gametes (eggs or sperm) are haploid cells containing only one set of chromosomes. When a cell undergoes meiosis to produce gametes, it divides twice, resulting in four cells with half the genetic information of the parent's body cells.

Explanation:

A C and D do not fit the picture.

Answer:

The correct answer is - 1133.

Explanation:

According to H-W equilibrium;

p2 +2pq + q2 = 1 ........... eq.1   and

(p+q)2 = 1 ..............eq.2

Here q = frequency of the recessive allele,

and p = frequency of the dominant allele in the population

The genotype of p2 + 2pq shows the dominant(taster) phenotype.

The genotype of q2 shows the recessive(non-taster) phenotype.

q^2 = (2400 - 1482)/2400

= 0.3825  

= 0.618

using eq. 2 we get p= 1-q

=0.382

2pq = No. of heterozygotes/2400

No. of heterozygotes = 1133.1648

Answer:

In most cells, DNA directs the production of a molecule of mRNA which then enters a ribosome. The ribosome produces the final product, a protein. Retroviruses do the opposite. They use the enzyme reverse transcriptase to use a template of mRNA to produce DNA.

Explanation:

The central dogma of molecular biology describes how a cell uses its genetic information to synthesize a protein. The first step called 'transcription' consists of using an RNA polymerase enzyme and a fragment of DNA (i.e., gene) as a template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, the genetic code in the mRNA sequence is read by the ribosomes in order to produce a protein, a process known as 'translation'. Retroviruses are viruses that have the ability to integrate into the host genome by using a reverse transcriptase enzyme that allows reverse transcription of mRNA to complementary DNA, which then integrates into the host's genome.

The correct options in the blanks are DNA, mRNA, Protein, mRNA, and DNA respectively.

It is the process by which cells produce protein from DNA molecules. DNA produces RNA which contains codes to produce amino acids.

The mRNA enters the ribosome which produced protein using the codons of mRNA.

Retroviruses have special machinery to produce the DNA from mRNA.

Answer:

Explanation:Coastal wetlands in the southeastern U.S. provide many important ecosystem goods and services. In addition to supporting important fish and wildlife habitat, they maintain coastal fisheries, store carbon, improve water quality, protect coastlines, and provide recreational opportunities. In many ways, coastal wetlands are dynamic and resilient ecosystems; however, they are being subjected to tremendous environmental change at the regional (e.g., hydrologic alterations, nutrient enrichment) and global scale (e.g., climate change).

One aspect of global change that is expected to have a substantial impact on coastal wetlands is winter climate change. Salt marshes and mangrove forests are common coastal wetland ecosystem types that occupy similar estuarine environments but have different climatic tolerances. In warmer climates, mangrove trees often outcompete salt marsh grasses. However, mangrove forests are sensitive to freezing temperatures, and within the region, mangrove forests are currently found only in Florida, Louisiana, and Texas (though isolated individuals have been reported in Mississippi). Salt marshes are more dominant along colder coastlines where mangroves are not able to survive freeze events. Future climate change is expected to result in increased winter temperatures and, potentially, reductions in the intensity of freeze events which could lead to mangrove forest replacement of salt marsh in parts of the Gulf of Mexico and southeastern Atlantic coast.

From a functional perspective, salt marsh grasses and mangrove trees are foundation species that control ecosystem dynamics and, in stressful and highly dynamic environments, provide the structural properties needed by other species; hence, the ecological and conservation implications of grass-to-tree conversions in coastal wetlands could be large (in both positive and negative ways). Dr. Mike Osland, USGS Research Ecologist and GCPO LCC staffer, along with 4 collaborating scientists, has initiated a study that addresses the following question: how might winter climate change impact the distribution and abundance of salt marshes and mangrove forests in the southeastern U.S.?

Their results begin to illustrate the vulnerability of salt marshes in the southeastern U.S. to mangrove forest expansion and quantify the amount of salt marsh habitat within each state that could be impacted by mangrove forest expansion under various winter climate change scenarios. The preliminary results are striking in terms of the potential for mangrove forest range expansion and coastal marsh displacement in the region. The hope is that these analyses stimulate additional discussion, research, and planning regarding the potential ecological and conservation implications of winter climate change for coastal wetlands in the southeastern U.S.

Answer:

Salt marshes are coastal wetlands found throughout the world on protected shorelines and on the edges of estuaries where freshwater mixes with seawater.

Mangrove forests are those which contain Mangroves which are trees and shrubs that grow in saline (brackish) coastal habitats in the tropics and subtropics.
