2. Cell Membrane

3. Cytoplasm

Answer:

The correct answer is = 2.5× 10^7.

Explanation:

Colony Forming Units/ml (CFU/ml) in the original sample can be calculated by the countable plate is multiplied by 1/FDF.

Given:

colonies counted on the plate = 250

Forming dilution factor = 10^5

solution:

CFU/ml = 250  x 1/1/100000

= 250 CFU x 100000

= 250,00,000 CFU/ml

= 2.5× 10^7

Explanation:

As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.

Only the dominant one is expressed.

Answer:

Trees and including all plants use the energy of sunlight and including the process of photosynthesis they take with the carbon dioxide or know as ( CO2) from the air and water from the ground. In this process of converting this into wood they can relase oxygen into the air.

Answer:

First off, chromosomes are thread like structures found in the nucleus of a cell containing genes, which determine a certain characteristic, and DNA which is the chemical that is the basic unit of inheritance.

All human cells ( excluding people who has cell abnormalities etc. ) contain 46 chromosomes. However there's this one pair of chromosomes called the sex chromosomes ( X and Y chromosome ) which defines whether the person is a make or female.

A male will have XY chromosomes, but a female will have XX chromosomes. That's how you differentiate.

Answer:

Antiviral drugs are a class of medication used for treating viral infections.[1] Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses.[2] Unlike most antibiotics, antiviral drugs do not destroy their target pathogen; instead they inhibit its development.

Antiviral drugs are one class of antimicrobials, a larger group which also includes antibiotic (also termed antibacterial), antifungal and antiparasitic drugs,[3] or antiviral drugs based on monoclonal antibodies.[4] Most antivirals are considered relatively harmless to the host, and therefore can be used to treat infections. They should be distinguished from viricides, which are not medication but deactivate or destroy virus particles, either inside or outside the body. Natural viricides are produced by some plants such as eucalyptus and Australian tea trees.[5]

Answer:You may feel hungry frequently if your diet lacks protein, fiber, or fat, all of which promote fullness and reduce appetite. Extreme hunger is also a sign of inadequate sleep and chronic stress. Additionally, certain medications and illnesses are known to cause frequent hunger.

Explanation:

"Hunger hormones" (ghrelin) in your blood and an empty stomach signal the brain when you're hungry. Nerves in the stomach send signals to the brain that you're full, but these signals can take up to 20 minutes to communicate -- and by that time, you may have already eaten too much.

Answer:

Parent 1 = RrBb

Parent 2 = RrBb

Explanation:

This question involves two genes in guinea pigs. The allele for rough coat (R) is dominant to smooth coat (r), and the allele for black coat (B) is dominant to white coat (b).

According to this question, two rough black guinea pigs when bred together produced two offsprings. One of the offsprings is rough white (R_bb) and the other is smooth black (rrB_). This means that, to produce such offsprings, the parents must be both heterozygous for both genes (RrBb). Please find the punnet square for this cross attached

[tex] \huge \sf{strain}[/tex]

A strain is a genetic variant or subtype of a microorganism (e.g., a virus, bacterium or fungus). Microbial strains can also be differentiated by their genetic makeup using metagenomic methods to maximize resolution within species.

Type strains are descendants of the original isolates used in species and subspecies descriptions, as defined by the Bacteriological Code [14], that exhibit all of the relevant phenotypic and genotypic properties cited in the original published taxonomic circumscription

Answer:

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.

Most traits are determined by more than two alleles. Multiple forms of the allele may exist, though only two will attach to the designated gene site during meiosis. Also, some traits are controlled by two or more gene sites. Both possibilities multiply the number of alleles involved.

Answer:

2

Explanation:

Everyone carries 2 alleles in Mendelian genetics. The exception to this is in polygenetic genes such as height. Alleles can be dominant, which is represented by a capital letter, or recessive, which is lowercase. A person can either have two recessive (aa), two dominant (AA), or a mix (Aa).

Answer:

Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. ... Minerals in a rock buried in soil will therefore break down more rapidly than minerals in a rock that is exposed to air.

Answer:

d isotope concentration

Explanation:

A fossil can be defined as the mineral impression or remains of living organisms such as plants and animals that are prehistoric in nature.

Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic.

We can accurately determine the age of a rock or fossil by measuring its isotope concentration. This can be achieved through the use of radiometric dating.

In Science, this process is known as absolute dating and it can be defined as a process used to accurately determine the age of a rock or fossil by measuring the decay of isotopes associated with the rock or within the fossils.

Hence, these informations when properly obtained is used to determine the age of a rock or fossil because the parent material decays into a stable daughter elements at a constant decay rate.

Answer:

The male's genotype is homzygous short (LL)

Explanation:

This question involves a single gene coding for hair length in guinea pigs. The allele for short hair (L) is dominant over the allele for long hair (l). This means that a heterozygote will have short hair (Ll) while a guinea pig with long hair will have genotype ll.

According to this question, a female guinea pig with long hair (ll) mates and have all heterozygous offspring (Ll). This means that the male guinea pig provided only the allele for short hair (L) that made the offsprings all short. In other words, the male's genotype is LL i.e. homzygous short.

Answer and Explanation:

The main environmental factors that can modify the life cycle not only of insects, but of all living beings are temperature, water availability and human activity, as variations in these factors can both prevent the life cycle from being completed, how you can accelerate and delay the phases of this cycle in different ways.
