Answer:

Dragonflies are important for our environment.

Explanation:

Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.

Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.

Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.

Answer: A tumor

Explanation:

A mutation that prevents apoptosis can disrupt the normal cellular mechanisms that prevent tumor formation, and lead to the uncontrolled growth of cells that could ultimately cause cancer.

A mutation that prevents apoptosis, or programmed cell death, can have several consequences. One of the most significant consequences is the accumulation of damaged or abnormal cells, which can lead to the development of tumors and cancer. Apoptosis is a natural process that eliminates cells that are no longer needed or that are damaged beyond repair. This process is essential for maintaining tissue homeostasis and preventing the growth of abnormal cells.

When cells are prevented from undergoing apoptosis, they may continue to divide and proliferate uncontrollably, leading to the formation of a mass of cells known as a tumor. This is because cells that have undergone DNA damage or that have other abnormalities are normally eliminated through apoptosis to prevent the accumulation of cells that could become cancerous.

Explanation:

If you cross two heterozygous tomato plants, you get four base genotypes of (Respectively,) RR, Rr, Rr, and rr. That makes your percentage A. 50%.

If a dominant red fruit (RR) plant is crossed with a recessive over yellow fruit (rr), then the phenotype will be red fruit and the genotype Rr. It is a case of complete dominance.

In diploid organisms (2n), an individual is homo-zygous when it carries two copies of the same gene variant (i.e., the same allele).

Moreover, an individual is heter0zygous when it carries two different alleles for the same gene locus.

In complete dominance, the dominant allele completely masks the expression of the recessive allele in heter0zygous individuals.

Thus, That makes your percentage A. 50%.

Answer:

during this process the nucleic of the male and female gametes are fused in order to create a zygote .known as fertilisation.Gametes contain half the number of chromosomes of all other cells in the organism .Meaning they are haploid .

Cells responsible for fertilisation:

fertilisation is the fusion of the nucleus of a male gamete with the nucleus of a female gamete ,producing a new cell called a zygote

Huntington's disease is caused by an inherited defect in a single gene, meaning yes it is likely. more likely will get symptoms between the ages of 30-40s

Answer:

The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

I. Constante de resorte, k = 150 Nm.

II. Fuerza = 67.5 Newton.

Explanation:

Dados los siguientes datos;

Fuerza, F = 30 N

Extensión, e = 0.2 m

Para encontrar la constante del resorte;

Fuerza = constante de resorte * extensión

F = ke

30 = k * 0.2

Constante de resorte, k = 30 / 0.2

Constante de resorte, k = 150 Nm

A continuación, para encontrar la fuerza para una extensión de 0,45 m;

Fuerza = 150 * 0.45

Fuerza = 67.5 Newton.

Hairy skin which helps kakapo's ancestors to live in harsh climate of New Zealand.

Explanation:

New Zealand's early ecology greatly affected the population of kakapo's ancestors because the environmental conditions for kakapo's ancestors are favourable and there is no invasive species which reduces the population of kakapo's ancestors near to extinction. The traits that were selected for the kakapo's ancestors provides ability to live and survive in the temperate and subtropical climates of New Zealand. The flightless trait in this bird is also responsible for its extinction because this bird can't run away from their predators.

Answer:

True

Explanation:

Moving a book so the potential energy of the system decreases is a true statement.

A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.

A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.

Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.

Therefore moving the book to a lower shell change potential energy, which decreases.

Answer:

C) the sun's rays that fall on the moon's surface.

Explanation:

The moon has different aspects and appearance because of the sun's rays that fall on the moon's surface. The shape of the Moon does not change itself, it occurs due to the sunlight. We only see that part of moon which is lit by the Sun. The phases of moon occur because the Sun lit different parts of the moon when the Moon revolves around the Earth so we can say that sun rays are responsible for the changing of shapes of the moon.
