b. Homologous recombination between the mutant DNA and the corresponding gene in the mouse genome

Explanation:

The Cre-lox recombination system is a versatile mammalian gene-editing tool used to produce site-specific recombination events in specific cell lines (e.g., embryonic stem or 'ES' cell lines) by facilitating the integration of a circular mol­ecule in genomic DNA. This system makes use of a Cre recombinase enzyme from bacteriophage P1 that has the ability to recombine specific sequences referred to as Lox sequences. By using this system, it is possible to generate knockout mice by crossing a strain of mice expressing Cre recombinase strain with a targeted loxP-flanked (floxed) mouse strain. The generation of a floxed mouse consists of 1-generation of a targeting construct containing homologous sequences with the mouse genome and loxP sites flanking the gene sequence of interest, and 2-homologous recombination of the targeting construct with the endogenous target gene sequence in the mouse genome.

Answer:

I think Gametes are mature male or female reproductive cells that fuse together resulting in a zygote during sexual fertilization. The key difference between somatic cells and gametes depends on the ploidy of the genome. Somatic cells consist of diploid (2n) genome while gametes consist of a haploid (n) genome.

Hope it help you!:)

Answer: Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.

Answer: B and C

Explanation: The sun always rotates on its axis because the Sun is fluid not solid, it spins faster at its equator (27 days) than at the poles (35 days). The Sun spins in the same direction as the planets orbit around it, which is not surprising as the Sun and the planets condensed from the same rotating disc of gas.

Answer:

At high temperatures or in the presence of catalysts, sulfur dioxide reacts with hydrogen sulfide to form elemental sulfur and water. This reaction is exploited in the Claus process, an important industrial method to dispose of hydrogen sulfide.

Because there is a limited amount of compost with a limited amount of minerals. In the garden there is loads of soil and loads of minerals. because of decomposition and absorption minerals can easily be replaced in the garden soil, unlike in a plant pot.

Answer: A

Explanation:

The fusion between 4 hydrogens (H) nuclei into a helium (He) atom releases the energy in main-sequence stars. In the Sun, it produces by proton-proton chain reactions.

In conclusion, energy is produced in the cores of main-sequence stars when lighter elements undergo the fusion into heavier elements (Option A).

Answer:

The correct answer is - 4. AMP has one phosphate molecule.

Explanation:

AMP or adenosine monophosphate is the secondary messenger and major component of ATP (the cellular energy form). As suggested by the name it has only one molecule of phosphate, unlike ADP that has two and ATP where three phosphates are attached to one sugar molecule and nucleobase adenine.

AMP has the least energy in comparison to the ADP and ATP as more energy releases when bonding breaks. It is interconverted to ADP and ATP in metabolic processes.

Which environmental factor would cause the greatest decrease in the number of species of plants and animals living in some of the lakes in the United States is acid rain

Acid rain refers to the precipitation of acidic components from the atmosphere to the Earth's surface. Some of the most common acidic components are sulfuric acid and nitric acid.

In conclusion, ACID RAIN is the environmental factor that causes the greatest decrease in the number of species of plants and animals living in lakes in the USA.

Answer:

See the answer below

Explanation:

A gene is made up of a pair of alleles that can be the same or different. When a gene is made up of the same allele, such gene is said to be homzygous and an individual is said to be true-breeding for that gene. When a gene is made of different alleles, such a gene is said to be heterozygous.

An allele, on the other hand, represents the alternate form of a gene. For example, height can be tall or short. Tallness represents one allele while shortness represents another allele. When the two alleles for a height are tall or short, it is homzygous, when it consists of one tall and one short allele, it is heterozygous.

Explanation:

The gravity of a planet is related to its mass and size. So, the correct option is (A).

Gravity is a fundamental interaction caused by the mutual attraction between all things that have mass or energy. The force of gravity keeps all the planets in orbit around the Sun.

It is a property of matter where all the matter is attracted to all other matter. The more matter there is, and the closer the objects are to each other, the greater the force of attraction and unlike electricity and magnetism, which can either repel or attract, gravity always pulls things together.

The magnitude of gravity depends upon the mass of each object and the distance between the centers of the two objects along with the he weight of an object is determined by the pull of gravity on it.

Thus, the gravity of a planet is related to its mass and size. So, the correct option is (A).

Birds, crocodiles and dinosaurs have much in common – including, it turns out, their breath. The hyper-efficient breathing system of birds is shared with alligators, and probably evolved in archosaurs, the common ancestor of crocodilians, birds and dinosaurs.

Answer:

No.

Explanation:

The characteristic of narrow leaves is present in desert plants but shallow roots are not present because water is not available in the upper layer of soil due to faster leaching of water. Desert plants have deep root system which helps them to extract water from the deep layers of soil. Narrow leaves prevent transpiration of water from the plant body which helps the plant to store more water inside its body and remain turgor.

Answer:

100%

Explanation:

My biology teacher taught me the FOIL method. F=first, O=outside, I=inside, and L=last.

TT x tt

The first letter of each parent together would be Tt, T=tall so the plant would be tall, 25%

The outside letter of each parent together would be Tt, T= tall so the plant would be tall, 25%

The inside letters of each parent together would also be Tt, T=tall so the plant would be tall, 25%

The last letter of each parent together would also be Tt, T=tall so the plant would be tall, 25%

Each outcome has a T, and that is dominant so therefore, the plants will always be tall. You could also think about it as a letter has to be passed down to each child and the first plant only has capitals to pass and the second only has lowercase to pass down.

100% of the offspring will be tall.
